A Mazda Dealership should me a Mazda cx5 2019, in 2023, at nearly 38k miles, right about where many have reported a cracked cylinder issue due to a manufacturing issue in age, and in milage. There is a lawsuit ongoing regarding the turbo version, however many reporting the same issue in the non turbo versions. My engine started smoking while on the highway causing a highly dangerous scenario to which I was barely able to make it to a mechanic where all the oil spilled out upon arrival. I got a diagnostic from a reputable mechanic confirming the cracked cylinder.

My wife's vehicle has a "Infotainment screen" (dashboard touch screen). There is a class action suit (CSP13d dealer letter) for issues regarding the screen performing tasks (Ghost screening touch) on its own. In lieu of a Mazda vehicle mass recall, they agreed to "FIX" the issue with a software update and replace the CMU Module of the vehicle to rectify this issue. I am here to report / advise you that MANY Mazda owners are NOT happy and have taken it upon themselves to disconnect these screens and do other "work around self repairs (removing/ disabling the unit) in order to fix the issues that occur. I have directly contacted Mazda in regards to my issues and they stat they can ONLY do what was advised on the court ordered settlement and NOTHING more to fix the issue. I want to advise you first hand, their FIX for this issue does NOT fix the problems. In fact, it is making it much worse! NOW my wife's vehicle is operating this screen by itself, WHILE driving, creating a MAJOR distraction. This "Ghost Touching" is actually going into the braking system settings and trying to change/ alter them AS she is driving! A MAJOR SAFETY ISSUE. She has had to, on several occasions, pull over /off the road, shut down the vehicle and try to "reset" what has occurred and check her system for ANY altered setting..if possible. As a retired Police Officer, I can tell you first had that if we ever encountered such thing/ safety issues reported by drivers, we would NOT allow them to travel any further with the vehicle and have it safely towed to a dealer or mechanic for repair. For their safety as well as the rest of the publics safety!! Mazda has refused to fully fix this issue and you can even see on numerous social media posts of MANY others reporting similar issues, disabling their devices on their own and doing other work arounds to mute or disable their devices totally. I Implore you to do a FULL RECALL of ALL affected vehicles to fix the problem ASAP!

Today I was using this vehicle and the cars my pocket got stuck in between the car seat dial for the movement of the car seat and the door and as I was in reverse the car seat started to move and pushed me all the way to the steering wheel as I was in a drive situation mode so I had to break it all off disconnected and everything

Engine has a crack in the head, well under 100,000 miles. It's a known defect but Mazda refuses to do anything about it. It is currently a very expensive paperweight sitting under our carport.

My 2019 Mazda CX-5 with approximately 78,000 miles developed a sudden major engine oil leak. The Mazda dealership diagnosed the issue as a cracked cylinder head and quoted approximately $5,600 for repair. The vehicle was properly maintained and this failure occurred without warning. A cylinder head failure at this mileage appears premature and may represent a defect. The oil leak created a large puddle under the vehicle and could pose a potential safety hazard due to loss of engine oil.
Engine, Mar 9, 2026
2019 Mazda CX5 has a cracked cylinder head. This is causing oil to leak out. The oil is leaking out onto the exhaust manifold which is causing the manifold to smoke and has the possibility to catch fire. Mazda is aware of this issue and issued CSP 11( customer service program). This does not cover the oil leak, only coolant leak. Several Class Action Lawsuits have been filed. Local Mazda dealership has inspected the car and confirmed the issue. The issue occurred suddenly with no warning. Again, Mazda is aware of this issue but has failed to issue a recall or service program to fix it, this is a dangerous issue as it can lead to a fire with the oil leaking onto the exhaust manifold.
Engine, Mar 5, 2026
My 2019 Mazda CX-5 started to smoke from the engine and I could smell oil burning. My car was due for an oil change so I brough it to a mechanic. After a diagnostic, they determined that there was a major oil leak and that the cylinder head was cracked and suggested I take it to the dealership. I did and they confirmed that there was a cracked cylinder head causing the massive oil leak. The technician even said in a video sent to me that the oil is leaking "in the same place as the others". I was then quoted 5,960.75 to make this repair. I did research and found that this is a manufacturing defect that is long known to Mazda. There is a TSB and a CPS that extends the warranty for this issue but only for turbo engines, not my non-turbo engine. My car is 2 years past the warranty but I only have 32K miles on it. I asked if Mazda could cover all or some of the cost since it is a defect, not caused by anything I did or didn't do. I was then told that because I didn't take my car there regularly for service, that they wouldn't cover it. I regularly took my car in for oil changes and other maintenance to a local shop as the nearest dealership was almost 30 miles away so it was very inconvenient. It's outrageous that Mazda won't issue a recall or extend the warranty for the same issue in the non-turbo engines. Asking me to pay 6K for a defect they caused is unconscionable.

My VIN indicates the 2.5L non-turbo SKYACTIV engine. Many 2019 CX-5 Touring models with this engine used cylinder deactivation, which is the version that has had some cylinder head cracking complaints. The engine type has documented failures my mileage (96k) is not extremely high for an engine The repair cost is very high (5,500) Mazda is refusing to help me out of goodwill assistance and ive only had the car for a year. They know this is a problem and fixed it for the turbos but not the non turbos! This is ridiculous, i expected a car to last more than 96k miles this can cause a fire or a stall and can cause a crash
Engine, Mar 5, 2026
I am reporting a premature engine failure on my 2019 Mazda CX-5 with approximately 55,000 miles. The vehicle developed a significant engine oil leak that was diagnosed by a repair facility as a casting failure in the cylinder head behind the timing cover. Due to the location of the leak and the nature of the defect, the entire cylinder head assembly had to be replaced. The total repair cost was $5,262.32, which I paid out of pocket. The repair documentation indicates that Mazda has issued a Technical Service Bulletin addressing this condition, but there is currently no recall or warranty extension covering the issue for my vehicle. A cylinder head casting failure at such low mileage appears premature and not consistent with normal wear and tear on a properly maintained engine. An engine oil leak of this nature could potentially create safety risks, including oil contamination of engine components or the possibility of oil leaking onto hot engine parts. Because this issue appears to be documented by Mazda through technical service guidance and has resulted in a costly major engine repair at relatively low mileage, I believe it should be investigated to determine whether a broader manufacturing defect exists that could affect other vehicles. I am submitting this complaint so that the issue is documented and can be evaluated for potential safety concerns or a future recall if similar failures are occurring in other vehicles.
Engine, Mar 3, 2026
The head on the 2.4L engine of the 2019 Mazda CX5 has shown a manufacturing defect that Mazda has addressed in certain models, but not all of the models with this engine. This leaves a large amount of vehicle owners with the financial liability to pay out of pocket for Mazda's engineering and manufacturing defect that they know about. The oil leaks onto the exhaust manifold creating a fire hazard. When driving our car, we cannot use outside air on the vents, A/C because the intake pulls in smoke coming from the engine compartment. I brought the car in today to Mazda and was denied any help in the repair, I am continuing with Mazda corporate to try and reach a resolution. Currently this will be roughly a $7000 repair. I do not have an estimate yet from the dealership.
Vehicle speed control, Fuel/propulsion system, Forward collision avoidance, Feb 27, 2026
I purchased a 2019 Mazda CX-5 (As is) on July 20, 2015. On September 11, 2025, as I was traveling on a three lane highway. I attempted to pass another vehicle. As I was attempting to go around the vehicle, my Mazda suddenly began braking and quickly losing acceleration. The speed limit on the highway was 70 mph. I estimated my speed at the time was between 70 and 75 mph as I attempted to pass. Pressing on the accelerator pedal did nothing. I had to try and very carefully steer the car to the right hand side of the road while trying to avoid oncoming traffic approaching from behind. When I finally got the car off the road, this is when I noticed that the car had stalled. The car started right back up and I continued to my appointment. The "radar cruise control" was activated at the time of the incident. On September 15, 2025, I contacted the dealer where the car was purchased and explained what happened. I was asked to bring the car in that same day. The car was supposedly looked over and connected to the Service Dept.'s computer to see if any error sign appeared. Nothing showed up. I service technician was then asked to ride with me to see if the car would replicated the same stalling as it has previously done. We could not get the car to stall as it had previously done. Before leaving, a salesman asked me if I wanted him to explain the "radar cruise control" to me some more. I agreed. The salesman then proceeded to tell me that "the car did not stall, it was simply braking from the activation of the radar cruise control". Being an experienced driver, I told the salesman that the car had stalled as evidenced by the fact that I had to restart it. The situation was not resolved to my satisfaction, but no other offers were made by the dealer. I requested additional diagnostic work to be done, but the dealer refused to cooperate. I did take the car to another Mazda dealer, but could get no offer but to connect the car to their computer.

The engine cylinder head cracked and is leaking engine oil. This component is available for inspection at Liberty Mazda or by an independent certified mechanic upon request. The cracked cylinder head caused significant engine oil leakage, which created the following safety risks: Sudden loss of engine power or stalling while driving Smoke emission from the engine bay Potential fire hazard if leaking oil contacted hot engine components These conditions placed both the driver, passengers, and others on the road at risk. The cracked cylinder head and associated oil leak were diagnosed and confirmed by Liberty Mazda, the authorized dealership that performed prior repairs on this vehicle. The dealership documented the issue and provided a repair estimate of approximately $5,400. No independent service center has inspected the vehicle at this time. The vehicle and cylinder head have only been inspected by Liberty Mazda. Mazda Corporate has not physically inspected the vehicle, but all service records and documentation of prior repairs have been submitted to them during the warranty dispute process. There has been no inspection by police, insurance representatives, or other third parties May 2025: The vehicle intermittently struggled to accelerate. At that time, no dashboard warning lamps illuminated, and the dealership initially reported no issues. June 2025: Following the timing cover repair, the vehicle experienced engine oil leakage due to incorrect sealant installation, which was documented. February 10, 2026: The dealership repaired the oil pan seal and replaced the sealant, refilling engine oil. February 14–15, 2026: Approximately four to five days after the February 10 service, the cylinder head cracked, causing a significant oil leak. All symptoms and related service events are documented in Liberty Mazda’s service records.
Fuel/propulsion system, Feb 25, 2026
My fuel pump burned out after only 60k miles.... very expensive repair. Mazda said the problem was only with the early 2019 models so mine wasn't included yet my fuel pump did exactly what the ones included in the recall did, but I was left with over $1700 repair bill to replace the fuel pump. Obviously the "improved design" used in the second half of the year isn't really improved, and I've never had to replace a fuel pump on a vehicle with so few miles on it. We were sitting idle waiting for food at a restaurant and the engine just died and we were unable to re-start the vehicle. No issues prior to this, always kept fuel at least 1/4 tank or more full and no engine warning lights until AFTER the engine died.
Electrical system, Feb 16, 2026
The touchscreen digitizer on the Mazda Connect infotainment system has developed a known defect causing constant phantom/ghost touch inputs. The screen registers random touches without any physical contact, causing the system to navigate through menus, change vehicle settings (including safety-related settings such as blind spot monitoring and heads-up display), exit navigation mid-route, change radio stations, and initiate phone calls to contacts without driver input while connected to Apple CarPlay. This is a significant driver distraction and safety hazard. When the system begins making random inputs, the driver must divert attention from the road to attempt to regain control of the infotainment system or end unintended phone calls. The issue occurs most frequently when the vehicle is stopped or at low speeds but also affects the system while driving. This is a well-documented hardware defect affecting 2017-2020 CX-5 models, acknowledged by Mazda under TSB 09-003/22. The cause is a failing touchscreen digitizer, not a software issue. Mazda has not issued a formal recall despite widespread reports. The component is available for inspection upon request. The vehicle has not yet been inspected by a dealer for this specific issue. No warning lamps or messages preceded the failure — the phantom touch inputs developed gradually and have worsened to the point that the infotainment system is nearly unusable. Current mileage is approximately 60,000-80,000 miles.

The vehicle's cylinder head has developed a structural crack at on the casting, a known manufacturing defect identified by the manufacturer in Service Advisory SA-037/23. This failure is causing pressurized engine oil to leak directly onto the hot exhaust manifold while the vehicle is in operation. The leaking oil is pooling on high-temperature exhaust components, creating a significant risk of fire while driving. The leak generates heavy smoke and noxious burning oil fumes that are entering the passenger cabin through the HVAC system, causing respiratory issues

Oil is leaking from the front timing chain cover and the vehicle is available for inspection upon request. The issue was caught early enough before it was an acute safety issue, however this issue can cause smoke while driving and cause the vehicle to lose function while driving, endangering those in and around the vehicle in motion. The vehicle only has 35,000 miles on it, has been confirmed and documented by an independent service center, and this is a widespread well-known issue - the service center has had three vehicles in this week with the same exact issue, and Mazda issued a technical service bulletin detailing the issue and stating the root cause is a lack of sufficient sealant applied during manufacturing. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives - only a service center. There were no warning lamps or messages of the problem prior to failure - I was lucky to have this caught during a routine inspection.

The vehicle has suffered a crack of the Cylinder Head Assembly which leads to engine oil leaking onto hot exhaust and fire hazard. This defect is officially documented by the manufacturer in Service Alert SA-031/21, which identifies a trend of aluminum heads cracking and leaking pressurized oil directly onto the hot exhaust manifold. Although Mazda has issued a 10-year/120,000-mile warranty extension (Program CSP11) for the exact same casting failure in its Turbo-equipped models, it has refused to provide similar "Goodwill" relief for my vehicle, despite it suffering from the identical engineering flaw. Mazda’s refusal to cover a verified latent manufacturing defect that poses a significant fire hazard is arbitrary and unfair. I am requesting that Mazda North American Operations provide full reimbursement for the $6,788.51 repair

I am being told there is a crack in the cylinder head that is a known issue for these vehicles. I have done some research online and it says that they installed defective cylinders in vehicles that were made between the years 2018-2020 leaving vehicle owners to pay thousands of dollars out of pocket due to a manufacturing defect. My car was smoking and smelling like something burnt even inside the car causing the driver to inhale those fumes, I took it to the shop and it turns out that the cylinder head is cracked and leaking the oil.
Electrical system, Other or unspecified, Jan 3, 2026
The vehicle is experiencing a “ghost touch” malfunction within the infotainment system, wherein the touchscreen registers unintended inputs. As a result, the system intermittently initiates phone calls, changes radio stations, and alters other settings without driver interaction. This erratic behavior is highly distracting and presents a potential safety concern while the vehicle is in operation.

Drove 39 miles, around ~55 minutes. Parked the car, realized that I parked a little too far from the spot, car just stalled while rolling. Pressed accelerator, nothing. Turned off the car, tried to start again, it cranked but didn't start. Had to tow it to the nearest mechanic (total of ~2 hrs until my car got picked up and dropped off), mechanic calls me and tells me my car started fine. I'm thinking it could be 5321K recall but not sure as my VIN is not in the recall nor did I get any recall notice. What component or system failed or malfunctioned, and is it available for inspection upon request? - No idea. How was your safety or the safety of others put at risk? - Got stranded for hours in the parking lot. Has the problem been reproduced or confirmed by a dealer or independent service center? - No Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - Yes, fuel cap like icon and check engine light were on when trying to start the car after it stalled. The car would crank but not start.

1. What component failed, and is it available for inspection? Component: The Engine Cylinder Head. The Failure: The cylinder head failed due to a structural crack caused by overtightened bolts (manufacturing defect), resulting in an engine oil leak. Confirmation: The defect is confirmed and resolved. Wayne Mazda (NJ) acknowledged the failure and replaced the cylinder head under the CPO Warranty last month. The issue has not returned since the replacement, proving this was indeed a hardware defect. 2. How was your safety put at risk? Fire Hazard: Before the repair, for a duration of one year, the vehicle leaked engine oil onto the hot exhaust manifold, creating a persistent fire risk. Toxic Exposure: My family and I were forced to inhale burning oil fumes inside the cabin for months due to the dealer's delayed diagnosis. This posed a significant health hazard. 3. Has the problem been reproduced or confirmed? Yes. The defect was initially identified by independent service centers (when the dealer failed to find it) and was ultimately verified and repaired by Wayne Mazda. The fact that the dealer performed the repair under warranty is an admission of the manufacturing defect. 4. Financial Damages & Request for Reimbursement: Since Mazda has admitted liability by fixing the vehicle, I request reimbursement for the losses incurred due to the delay in diagnosis: $2,000+ in Independent Repairs: Because Wayne Mazda initially failed to diagnose this warrantable defect, I was forced to pay independent shops to diagnose and attempt to fix the oil leak to keep the vehicle safe. These costs were a direct result of the dealer's inability to identify the manufacturing defect. $159.29 in Uber Fees: Mazda failed to provide a loaner vehicle during the major powertrain repair, forcing me to pay for my own transportation. Conclusion: I am filing this report to: Document this safety defect (Overtightened Cylinder Head Bolt / Oil Leak) for NHTSA records, as it poses a fire

On 12/10/25, my 2019 CX5 NA had major oil leak after smelling a burning smell for a few days. Took it into local mechanic and he couldn’t find the leak, did an engine wash and additional testing before identifying a crack in the cylinder head; the leak was coming from the exhaust manifold. There was oil all over the engine and the underbelly of the vehicle; according to the mechanic, I was lucky the car didn’t start on fire with the amount of oil. I was informed that this is a common problem with the turbos and the NAs but the extended warranty only included the turbo engines. Contacted Mazda customer experience and set up an appointment. Vehicle went to the Mazda dealership on 12/15 and it was confirmed that there was a crack in the cylinder head and received an estimate of $11,000 needed for repairs. $7000 of that was for a new cylinder head. This was after an independent mechanic inspected my vehicle and stated everything looked good besides the main issue and needing new rear breaks in the next few months. 12/15-contacted Mazda customer experience and and case file was opened. 12/16-contacted customer experience back due to not receiving a call and received the name and extension of the assigned case manager. 12/17- still had not received a call back and left voicemail for case manager. Requested a call back to myself and the dealership; received a call back a few hours later and I was never asked what happened but was informed that Mazda corporate could not help me due to the warranty being expired. I am now required to pay over $250 to the dealership for an inspection of the vehicle I never requested. There were initially no warning signs but then the low oil light came on after 3 days of smelling something burning.

The 2019 CX-5 AWD with the 2.5L NA engine (with Cylinder Deactivation) has an engine oil leak coming from the cylinder head area. The Mazda dealer confirmed the leak source and found burnt oil on the exhaust. The component is available for inspection. The leak location and symptoms are consistent with the known porous/cracked cylinder-head defect documented in this engine family. Full confirmation requires teardown. In early Dec 2025, a burning oil smell began, then thick white smoke came from under the hood while driving and after stopping. This created an immediate fire risk, and rapid oil loss could cause sudden engine failure or stall in traffic. The issue was inspected and confirmed by an independent mechanic, who noted the leak could only be traced after removing the exhaust manifold. The Mazda dealership then inspected it and confirmed the leak source at the cylinder-head area and the burnt oil residue. The problem has been reproduced and confirmed by both the independent mechanic and the Mazda dealer. No warning lights or messages appeared prior to the smoke. Mazda has an extended warranty program for the same cylinder-head defect on the Turbo engine, but no equivalent coverage exists for the NA engine, despite the identical safety risks.

While driving a short distance, my engine overheated and there was a strong burning smell. The cylinder head was cracked, causing a significant oil leak. The car is currently at the dealership but is available for inspection upon request. The defective cylinder head is leaking engine oil directly onto hot exhaust components. This creates an immediate risk of engine fire and causes smoke to enter the vehicle cabin, impairing visibility and driver health. The vehicle was diagnosed by an authorized Mazda dealership. They confirmed the cylinder head is cracked and requires replacement. My mechanic advised this type of leak could lead to engine overheating, sudden power loss, or potential fire risk and should not be driven. Mazda has issued prior Technical Service Bulletins and warranty extensions for similar cylinder head/manifold cracking issues on the 2.5L turbo engine, but no program exists for the non-turbo engine, despite identical problems. Mazda should be held responsible for this safety issue. Mazda is aware of this manufacturing defect but has not recalled these engines to be repaired or replaced if they are outside of their warranty period, placing costly repairs and potentially life-threatening situations on their customers. The repair is replacement of the cylinder head/sleeve or replacement of the engine block, which has since been modified by Mazda to resolve this issue. Mazda’s refusal to extend reimbursement to non-turbo owners is unfair and leaves affected customers with no support for a known manufacturing flaw. I urge NHTSA to investigate this recurring engine defect in non-turbo 2019–2020 Mazda CX-5 models and encourage Mazda to offer equal reimbursement.
Electrical system, Dec 4, 2025
Summary of Issue: The infotainment system in my 2019 Mazda CX-5 has been malfunctioning for a long period of time, and the issue has now escalated to the point where the system is unsafe and distracting while driving. Details: The infotainment screen intermittently “ghosts” and activates functions on its own—clicking through menus, changing settings, and moving erratically without any driver input. The system has also frozen and rebooted while the vehicle is in motion. This creates a serious distraction and safety concern. I previously reported this issue to the dealership, where they attempted a reset and told me to come back if the problem returned. The issue persisted and worsened. I recently returned, and the dealership diagnosed a communication failure between the CMU and the infotainment screen. However, they cannot identify any cause, and the screen itself has no physical damage and has never been struck. Mazda has declined to cover this under warranty, even though this appears to be an internal failure of components that should not fail at this mileage. Additionally, infotainment failures in Mazda vehicles have been the subject of prior complaints and service bulletins. Safety Concern: The malfunction causes the screen to operate unpredictably while driving, which distracts from the road and creates a risk of an accident. Because the system controls access to vehicle settings, Bluetooth, audio, navigation, and backup camera interfaces, the failure presents a potential safety defect. Requested Action: I am requesting that NHTSA investigate whether this infotainment / CMU communication failure is a broader defect affecting 2019 Mazda CX-5 vehicles, as dealerships cannot identify the cause and the failure poses a clear distraction hazard.
