Vehicle speed control, Engine, Sep 17, 2026
I leased my 2017 Hyundai Elantra new in July 2016 and later purchased it. As of September 2026, it has approximately 77,000 miles. I am reporting two unresolved safety concerns despite repeated repairs and more than five months of seeking assistance from Hyundai. Multiple ignition coils have failed during my ownership. Most recently, I paid approximately 400 for service after another coil failure. Although the check engine light is no longer illuminated, the vehicle continues to struggle to accelerate and abruptly jerks or “burps,” particularly around 30 mph. At times, I must press the accelerator nearly to the floor to gain enough speed to safely merge onto the highway. I commute approximately 40 miles round trip, including stop-and-go highway traffic, and am concerned about my safety. When I reported that the symptoms continued after the repair, the Hyundai dealer said I would need to pay another diagnostic fee while also stating their equipment might not identify the problem without an illuminated check engine light. My driver-side exterior door handle is also completely inoperable. This issue was previously repaired by Hyundai under warranty and a known issue with the model year, but the repair has failed and the driver’s door cannot be opened from outside. To enter my vehicle, I must climb through the front passenger door, lower the driver’s window, exit, walk around the vehicle, reach through the window, and open the door using the interior handle. After more than five months of contacting Hyundai and seeking service, both issues remain unresolved. I am concerned about the safety of continuing to operate this vehicle and about the failure of a previously completed recall repair. I am requesting that NHTSA document and review these safety concerns.

I bought my 2017 Hyundai Elantra SE earlier this year with about 119,000 miles. It had good maintenance records when I bought it, and it now has about 128,000 miles. Since buying it, I've had two oil changes done along with new spark plugs, coils, front brake pads, and tires. About two days before the engine failed, I noticed the car had suddenly burned through a significant amount of oil. There was no visible oil leak. The car stopped running, so I had it towed instead of continuing to drive it. Oil was added, and afterward it started and seemed to be running fine.The next day, I was driving approximately 70 mph on the interstate when the car suddenly lost acceleration and warning lights came on. There was smoke while I was driving, including smoke/fumes coming into the car. Afterward, there was oil everywhere. The car had to be towed again and is no longer drivable.What concerns me most is how quickly this happened. The car went from suddenly consuming oil with no visible leak to losing acceleration and experiencing a major engine failure while I was traveling 70 mph on the interstate. Losing power at that speed was dangerous, and the amount of oil and smoke also made me concerned about the possibility of a fire. Hyundai has told me the vehicle is no longer under warranty. I have not paid for an extensive engine teardown yet. My grandfather looked and he said it appears the engine threw a connecting rod through the side of the engine block. With the valve cover off, the engine looked brand new. I'm filing this complaint because an engine suddenly losing power at interstate speeds, along with oil and smoke, is a serious safety concern, especially with the potential for a fire. I hope NHTSA will compare this incident with other complaints involving engine failure and excessive oil consumption in 2017 Hyundai Elantras. Currently, it's available for inspection.

The contact owns a 2017 Hyundai Elantra. The contact stated that while driving 50 MPH, there was an abnormal knocking sound coming from the engine. The contact pulled over to the right side of the road, turned off and restarted the vehicle, and the vehicle operated as intended. No warning light was illuminated. An independent mechanic was contacted. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the engine needed to be replaced. The engine was replaced, and the vehicle was repaired. The manufacturer was not notified of the failure and referred the contact to the BBB to report the issue. The approximate failure mileage was 108,404.

Vehicle stalled while driving on a highway without warning. The car was able to start back up, would go a few feet and stall again. Had it towed to a Hyundai dealership to repair. They replaced the exhaust camshaft and timing components. They released the car, saying it was fixed. Less than 12 hours later, the car stalled again while driving through Washington DC. Once again, it would start up again but stall every few feet. We took it to another Hyundai dealership. They replaced the oil pump (saying the oil pressure was too high). That did not fix the issue and the dealership stated that the intake camshaft needed to be repaired. The third party warranty company would not approve that repair, as they are saying the engine needs to be completely replaced. We bought the car in March. The first incident occurred in June and the second incident was 12 hours later. The car has been at the dealership for 'repairs' ever since.

While operating my 2017 Hyundai Elantra under normal driving conditions at approximately 70,000 miles, the engine suffered a sudden, catastrophic loss of motive power and stalled completely while moving in active traffic without any prior warning. This severe stalling event occurred despite the vehicle being strictly and meticulously maintained according to all manufacturer guidelines and scheduled service intervals. Prior to the stall, the Check Engine Light illuminated. A comprehensive diagnostic scan completed at an authorized Hyundai dealership confirmed active trouble codes P0014 (Exhaust Camshaft Position Timing Over-Advanced) and P0017 (Crankshaft-Camshaft Position Correlation Error). The internal physical engine timing assembly and Variable Valve Timing (VVT) components slipped out of synchronization, forcing an abrupt, automatic engine shutdown while navigating active roadways. This failure created an immediate, severe safety hazard and high collision risk due to the sudden loss of vehicle propulsion, power steering assist, and vacuum brake booster pressure, leaving me vulnerable in traffic. This structural timing deviation caused chronic engine misfires and forced raw, unburned fuel directly into the exhaust stream. This unburned fuel completely fouled and destroyed the primary Oxygen (O2) Sensor due to heavy carbon contamination and extreme thermal stress. The failed sensor and incorrect valve timing totally disrupted the electronic control unit's air-fuel management, inducing the unpredictable stalling hazard and causing an immediate, automatic state emissions/smog inspection failure. Repairing this underlying manufacturing and metallurgical defect at the official Hyundai dealership required an extensive mechanical teardown and replacement of the timing components, costing approximately $2,500 out of pocket. This exact failure pattern, cascading O2 sensor damage, and diagnostic trouble codes match hundreds of existing complaints with NHTSA.

1. The engine architecture suffered a catastrophic mechanical failure. Specifically, severe, systemic internal oil consumption/vaporization starved the hydraulic timing chain tensioner of critical hydrostatic pressure. This caused the tensioner to collapse, creating slack in the steel timing chain, which then "jumped time" (skipped a tooth on the camshaft sprockets), causing the engine to instantly seize and lose all motive power. The vehicle and engine are fully intact and available for inspection at Pohanka Hyundai of Fredericksburg. 2. The vehicle suffered a sudden, complete loss of motive power and engine seizure while being driven at night on an unlit, dark secondary roadway. The driver (my daughter) was left suddenly stranded without power in a highly vulnerable, pitch-black location with passing traffic, presenting an immediate collision hazard and a severe personal safety risk before emergency assistance could arrive. 3. Yes. The vehicle was towed to an authorized Hyundai dealership (Pohanka Hyundai of Fredericksburg), where service technicians officially diagnosed that the engine had "jumped timing" and suffered a complete failure of the timing system, alongside a noted lack of engine oil volume due to vaporization. 4. The vehicle has been formally inspected and diagnosed by the authorized Hyundai dealership service department under Hyundai Motor America Corporate Case #[XXX]. No police or insurance inspections were required as no collision occurred. 5. No dash lights or warnings before failure. However, for a year prior, the engine exhibited severe internal oil vaporization, requiring constant top-offs between scheduled oil changes to maintain safe levels. There were zero external fluid leaks on the engine or ground; oil burned entirely internally. This chronic volumetric oil loss directly caused the sudden drop in pressure, hydraulic tensioner collapse, and catastrophic engine seizure.

I own a Hyundai Elantra with approximately 103,000 miles. The vehicle has developed an intermittent issue where the engine will suddenly stall while driving. This most often occurs when I am decelerating and turning, such as when entering or navigating roundabouts. At the time of the stall, multiple warning indicators appear simultaneously, including the check engine light, battery warning light, and a “no key detected” message. There are no prior warning signs before the failure occurs—no unusual noises, no loss of power leading up to the event, and no dashboard warnings in advance. The stall is sudden and unexpected. When the vehicle stalls, I must quickly shift into park and restart the engine. The car restarts immediately without hesitation, and all warning lights disappear. The vehicle then operates normally again until the issue randomly reoccurs. This has happened multiple times. This issue creates a safety risk because the vehicle loses power unexpectedly while in motion, particularly during low-speed turns and in roundabouts, which could increase the risk of a collision due to sudden loss of propulsion and reduced control. The problem has not yet been formally diagnosed by a dealer or independent repair shop, but based on research and similar reported cases, it may be related to an intermittent engine or electrical signal failure. The issue has not yet been inspected by the manufacturer, police, or insurance representatives. UNKNOWN as to the exact failed component, but the failure appears to involve a sudden loss of engine operation without warning, followed by immediate recovery upon restart.
Electrical system, Other or unspecified, Engine, Apr 11, 2026, fire
Component or system failed: The electrical and/or engine system failed spontaneously. Gray smoke originated from under the hood, followed by black smoke and an intense fire. The vehicle is NOT available for inspection as it was declared a total loss and scrapped 30 days after the incident. Safety risk: My safety was at immediate risk as I was inside the vehicle when the fire began. Public safety was also threatened; the Bloomingdale Fire Department had to evacuate a Wendy’s restaurant and its customers for two hours due to the intensity of the fire and smoke. Confirmation of problem: The problem was confirmed as a Total Loss due to fire by the Bloomingdale Fire and Police Departments on the scene. Inspections: The vehicle was inspected at the scene by police and fire officials. No manufacturer or dealer inspection was possible because the fire occurred only 7 days after purchase and the vehicle was destroyed. Warning symptoms: There were no warning lamps, messages, or symptoms prior to the failure. The smoke appeared suddenly while the vehicle was parked and idling.

I am filing a formal complaint regarding my 2017 Hyundai Elantra SE (VIN: [XXX] ). The vehicle is currently experiencing severe safety issues, including unexpected engine stalling and loud mechanical rattling, alongside a P0014 diagnostic code. These symptoms align directly with the defects described in Recall 203 (NHTSA 21V301000) involving improper piston ring heat treatment and Service Campaign 966regarding engine bearing wear. As a consumer, I am extremely concerned about the risk of a crash due to sudden loss of power. I am really concerned for my son and I as I drive my vehicle. I am requesting: 1. An immediate inspection and confirmation of eligibility for an engine replacement at no cost to me. 2. Verification of the lifetime long-block warranty extension associated with the KSDS (Campaign 966) update. 3. Provision of a loaner vehicle or rental reimbursement while my primary vehicle is unsafe to operate. Please assign a case manager to this matter and provide a timeline for resolution.

Car was constantly losing power, called Hyundai dealer about the OBI system thinking that could be the cause they told me no, and then in 2 years ago the car started stalling when you slowed down and on the way home from work it completely died. Car still turns over but car will not go, engine and transmission are completely done. It’s been at my house sitting since. Hyundai dealer is a joke a wouldn’t help when the issue first arised.

After no previous issues, car stalled out multiple times on short drive to work. No warning lights and no subsequent diagnostic codes were reported. Upon final restart, engine started knocking severely. Upon investigation, the oil stick showed no oil in the pan. Vehicle was towed to trusted, licensed mechanic for evaluation where we were informed about the potential of a failure due to rapid oil consumption. The mechanic confirmed the engine failure to to oil loss. Vehicle had received regular, documented maintenance and fluids were checked periodically between cycles. There was no low-fluid indicator prior to the mechanical failure. Dealership-level conversations confirmed the rapid oil consumption issue for the 2017 Elantra is common, but because the vehicle VIN was not listed as part of a prior recall no assistance could be provided to repair the engine. The dealer provided a full cost quote of $9,000 to replace the engine block with a remanufactured unit.

Driving on the highway in the far left lane. Check engine light came on, car stopped accelerating. Car came to a stop, car shut off. Smoke was coming out from under the hood and flames were seen underneath the car. Police and fire department arrived. Report states an electrical fire. Had car towed to Hyundai. Hyundai stated that the engine seized followed by the starter catching on fire. Car was only 2,000 miles in from last oil change. Was up to date on maintenance and safety inspection. Hyundai also stated there was a hole in the engine block. No prior issues with the car. The car would need roughly $16,000 in work done, confirmed by Hyundai. Car is now totaled. Car only had 121,000 miles on it.

With no 'low oil' warning, the car's engine started may a knocking noise. Then, all kinds of warning lights started. Parked the vehicle and checked the oil the next day and there was NO OIL in the engine. This should not have been the case considering this car gets regular oil changes. Also, there was no oil spots or stains on the driveway to also indicate an oil leak. This happened to my son while driving home from work on the interstate at 10:30 at night. That is concerning.

While driving, pressing the accelerator pedal, the vehicle hesitated and stalled. No warning lights came on until after I attempted to turn the vehicle back on then the check engine light and low oil light were illuminated. My vehicle was towed to a local mechanic and I was informed that the engine was blown and to tow my car to a Hyundai dealership as I was still under the 10 year/100k mile warranty. After getting my car to Hyundai, I was told I had to get a combustion cleaning for $800 whether the cleaning worked or not before any warranty work could be completed. The cleaning did not work and it was then found that a pin was sheared off inside the engine. My engine was then replaced under warranty but I still had to pay for the cleaning. A second mechanic looked over my paperwork after getting my car back 2 months later and noted that the engine failure could have been diagnosed without the cleaning as the cleaning would not have affected where the pin was sheared off. My 2017 Elantra had 90,315 at the time of this incident.

to whoever it is that can help, I am reaching out to submit a formal complaint regarding my 2017 Hyundai Elantra due to ongoing mechanical and structural issues that began very shortly after I purchased the vehicle, which have progressively worsened. I made the purchase in January 2024 for approximately $13,000 with 60,000 miles. The vehicle now currently has approximately 108,000 miles. Since purchasing the car, I have experienced consistent time consuming and serious issues that I believe indicate defects in manufacturing or design. First, the thermostat had failed during the first winter season I owned the Elantra, despite replacement the vehicle’s heating system still does not function properly. I’m not a fan of the cold. Also, the engine burns oil at an extreme rate. I am required to add oil literally every 2–3 days to prevent the engine from running dry, which presents a serious risk of engine failure and potential safety hazards while driving. And is also costly as oil is not cheap. In addition, the vehicle’s headlights developed spiderweb pattern cracking and shattered from the inside after approximately nine months of use, without any external damage. The paint has chipped across the vehicle, including in door jambs and other protected areas, suggesting poor paint quality. And recently, the lower engine underbody cover has completely broken down and disintegrated over time due to clips constantly falling out. Given the age of the vehicle and the normal use, the amount and severity of these issues are unacceptable. These defects have caused significant financial burden and raise serious concerns on vehicle safety and manufacturing quality. I am requesting that this complaint be reviewed for potential defects or recalls. I would also like Hyundai to be held accountable, either through compensation for the repairs required or replacement. Thank you for your time and attention to this matter. Sincerely, Owner of the 2017 Hyundai Elantra

Component or System Involved Engine and internal lubrication system. The engine and related components are available for inspection upon request. Description of the Problem In January 2025, this vehicle experienced a catastrophic engine failure and seized. An independent repair facility inspected the engine and reported metal fragments in the engine oil, indicating internal engine damage. The vehicle was then transferred to a Hyundai-authorized dealership for major engine repairs, which were completed on January 18, 2025. Less than one year later, the vehicle developed excessive oil consumption. In October 2025, the engine stalled and was found to have no oil, despite having received an oil change approximately one month earlier. The vehicle is currently undergoing Phase 2 of Hyundai’s oil consumption testing. The dealership has indicated a full engine replacement will likely be required. Oil consumption has been measured at approximately 1.5 quarts per 1,000 miles. This vehicle is not currently included in Hyundai’s engine recall or warranty extension, despite being the same make, model, and model year as vehicles that are covered and exhibiting the same failure characteristics. Hyundai and NHTSA have documented similar engine defects on other Elantra models due to piston oil ring issues, resulting in excessive oil consumption and engine failure. My vehicle exhibits the same symptoms and failure mode. Safety Risk Excessive oil loss can result in sudden engine stalling or seizure without warning, creating a risk of loss of propulsion while driving, including at highway speeds. Confirmation or Reproduction of the Problem The failure has been confirmed by an independent repair facility and by a Hyundai-authorized dealership through inspection and ongoing oil consumption testing. Inspections by Others The vehicle has been inspected by both an independent repair facility and a Hyundai-authorized dealership.

I've owned a 2017 Hyundai Elantra for a few years now, and it has been a headache. Over the course of the past year and a half, the engine has went out (seized) not once, not twice, but three times without any warning. I go to start the car one day and the engine bay starts shaking and power of the engine goes either completely out or down significantly. It feels like a gamble every few months of if my car will simply stop working. I've had the engine rebuilt twice already and will probably have to have it rebuilt again for the same issue (the timing).
