Exterior lighting, brake lights, switchNov 16, 2015
Hyundai Motor America (Hyundai) is recalling certain model 2011-2012 Sonata vehicles. The brake pedal stopper pad can deteriorate allowing the brake light switch plunger to remain extended when the brake pedal is released.
If the brake light switch plunger does not retract as it should when the brake pedal is not being pressed, the brake lights may stay illuminated preventing accurate communication to rearward following vehicles that the vehicle is slowing or stopping. Additionally, if the brake switch plunger is not retracted, then the transmission can be shifted out of PARK without depressing the brake pedal. Either condition increases the risk of a crash.
Hyundai will notify owners, and dealers will replace the brake pedal stopper pad with an improved part, free of charge. The recall began on January 6, 2016. Owners may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for this recall is 136.

Hyundai Motor America (Hyundai) is recalling certain model year 2011-2012 Sonata vehicles manufactured December 11, 2009, to April 12, 2012 at Hyundai Motor Manufacturing Alabama and equipped with either a 2.0 liter or 2.4 liter Gasoline Direct injection engine. In the affected vehicles, metallic debris may not have been fully removed during manufacturing of the engine crankshaft. If the debris was not completely removed, oil flow may be restricted through the connecting rod bearings, causing connecting rod damage. A worn connecting rod bearing will produce a metallic, cyclic knocking noise from the engine and possible engine failure.
Engine failure would result in a vehicle stall, increasing the risk of a crash.
Hyundai will notify owners, and dealers will inspect the vehicles and replace the engine assembly, as necessary, free of charge. Additionally, Hyundai Motor America will increase the warranty for the engine sub-assembly (short block) to 10 years/120,000 miles for both original and subsequent owners of 2011 and 2012 Sonatas manufactured at Hyundai Motor Manufacturing Alabama equipped with 2.0 liter and 2.4 liter Gasoline Direct injection engines. Interim notifications were mailed to owners starting on October 8, 2015. A second notification will be mailed when parts are available.

Power train, automatic transmissionJul 18, 2014
Hyundai Motor Company (Hyundai) is recalling certain model year 2011-2014 Sonata vehicles manufactured December 11, 2009, through May 29, 2014. In the affected vehicles, the transmission shift cable may detach from from the shift lever pin.
If the transmission shift cable detaches, the transmission gear selection may not match the indicated gear and the vehicle may move in an unintended or unexpected direction, increasing the risk of a crash. Furthermore, when the driver parks the vehicle, despite selecting the 'PARK' position, the transmission may not be in 'PARK.' If the vehicle is not in the 'PARK' position and the parking brake is not applied, there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
Hyundai will notify owners, and dealers will inspect and, as necessary, repair the connection between the shift cable and shift lever, free of charge. The recall began in September 2014. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 123.

Hyundai Motor Company (Hyundai) is recalling certain model year 2006-2009 Accent, model year 2007-2011 Azera, Sonata and Sante Fe,2006-2011 Tucson, 2009-2011 Elantra Touring, 2007-2010 Elantra, 2008-2011 Veracruz, 2009-2011 Genesis, 2010-2011 Genesis Coupe, 2007-2008 Entourage, and 2006-2008 Tiburon vehicles. Originally, in April 2013, Hyundai recalled 1,059,824 model year 2007-2009 Accent and Tucson, model year 2007-2010 Elantra, model year 2007-2011 Santa Fe, model year 2008-2009 Veracruz, model year 2010-2011 Genesis Coupe, and model year 2011 Sonata vehicles. In September 2013, Hyundai informed the agency that it was adding more vehicles to this campaign, representing an additional 652,512 units. The total number of vehicles being recalled is now 1,712,336. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake transmission shift interlock feature, preventing the shifter from being moved out of the PARK position and cause the Electronic Stability Control (ESC) malfunction light to illuminate.
Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of Park without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
Hyundai will notify owners, and dealers will replace the stop lamp switch, free of charge. The safety recall began on April 22, 2013. Owners may contact Hyundai at 1-800-633-5151. Hyundai's recall campaign number is 110.

I had taken my Sonata to Mike Miller Hyndia in Peoria,I'll and they agreed to do the recall although they had my vehicle for two weeks. They did not service it and when I picked it up they said I had to drive it till the service engine light come on. I was driving it five days later and heard a loud noise and car started malfunctioning I was stuck in a middle of a intersection and I had to push vehicle off road. I broke my right hand in this process and I have also lost my job I am very concerned why they did not service it after they agreed too and sent me off in it in that condition ..The car is currently parked and unsure what to do with it ..

The vehicle suffered an internal connecting rod bearing failure, a known manufacturing defect affecting the Theta II GDI engine. The failure was explicitly diagnosed via the manufacturer - specific OBD-II fault code p1326 Knock Sensor Detector System. This defect causes sudden engine stalling poses an immediate risk of catastrophic engine failure or fire while driving. Hyundai Motor America has denied financial reimbursement for the required engine repair because the work was completed by an independent shop and third-party arbitration deadline (BBB Auto Line) communicated to me. The manufacturer is actively refusing to remedy an acknowledged safety defect.

On the freeway at night when headlights and back lights quit working. Got off freeway and were able to temporarily fix it. A few months later while parked in driveway and not in use for a couple of days, lights came on without our knowledge and drained our battery. Neighbor alerted us to the situation.

Intermittent and sudden loss of power steering nearly caused an accident for both of sons when each one was driving on two separate occasions this past week. "EPS" and traction control warning lights both illuminate on the dash when steering goes out. Sometimes the codes will clear themselves out after restarting the vehicle, but not always. Had it inspected by an independent service center and they cleared out the codes with their scanner. Steering worked fine for a few days afterwards, but then suddenly lost power steering again yesterday. It is very dangerous to drive and it is very unpredictable. I see that there was a recall for this issue for certain manufacture dates for 2011 Hyundai Sonata, but mine was not part of the recall. I believe that it should be part of that recall before someone dies or is injured.

I test drove the vehicle at an auction, watched several other people test drive the vehicle. Before the auction I test drove it one more time and put my obd scan tool on it to make sure there were no hidden codes or problems. I won the bid,and picked up the vehicle. I drove it approximately 6 miles from the auction and the falshing engine light popped on. I immediately pulled over in heavy freeway traffic. Put my scan tool on it and found out the knock sensor had triggered. The vehicle was shaking and making a terrible racket. It was inoperable in the worst possible spot on Highway 51 during rush hour traffic. I managed to slowing coast down the offramp and roll into a parking lot. I then called Purdy Hyundai and spoke with a service advisor and provided the VIN#. He (Vue Kue) informed me that the vehicle qualified for the recall and warranty work based on exactly that issue. I had the vehicle towed to the Purdy dealership on July 8th 2026. I was told today that it was unlikely that Hyundai would honor the recall because I did not have service records of a vehicle I had owned for 6 miles of driving. I filed a complaint with Hyundai corporate. Claim#43010067 and awaiting the reconciliation of this situation. Of which they appear to to be avoiding.

I purchased fgis car from a used car dealership, for over $6,000.00 , which is not a ton of money, but plenty enough to not have instant issues. Since my purchase in june 30, 2026, i have already had all of these issues occur. There is white smoke coming from the left tail pipe, it is sluggish when you push on the gas, there is black soot constantly on my rims that is extreamly hard to remove, the high pressure fuel pump jas failed, I can tell because the oil is higher then it was when o had the oil freshly changed, and it smells of gasoline.inside the oil. The exhaust has stron smell of gasoline. My steering wheel has a loud clinking noise everytime I go over a speed bump on pull into my driveway. Just so many items consistently needing repair or replacement, even though I just had the fuel system cleaned, the oil changed, and filters, and.oil filter too. I checked to see if any of my issues are covered by a recall warranty, because they all are recalled items for my car year, make, and model, but apparently Hyunfai is only covering these dangerous recall items for ul to 10 years. These items shkuld be covered longer, because my carfax states that at least one of these recalled items had already been changed in 2018, and is already broken again!! Hyundai should have covered these extreamly high wear out car parts for a longer period of time, or for the life of the vehicle, if every 5 years your replacing a $1000.00 part, not including labor, like the (HPFP) I was quoted by auto zone for over that price point!! "Ridiculous"! Another item is the air bag cover on the driver side windows area, of the body frame it is loose and keeps un-clipping, i am afraid that it is going to possibly just go off and kill me or something!! Very disappointed right now, that i cannot get any of these recalled items replaced by the manufacturer!!

I was heading to work when suddenly smoke started pouring from the air conditioning vents, and the ABS and traction control warning lights came on. I hit the brakes to pull over, only to realize I had lost braking power. I managed to steer to the side of the road as carefully as possible and bring the car to a stop—despite having no brakes and a fire burning under the hood. I tried downshifting to slow the vehicle, but the transmission didn't respond, and the cabin began filling with smoke. Once I stopped, there was nothing I could do to extinguish the fire, as the car was completely consumed within seconds. It was a fire in the engine bay; I lost the brakes, and the ABS and traction control lights lit up. I assume it was a critical failure in the braking system, most likely involving the ABS module.

Now I cannot control the radio, phone or even toggle to see mpg, mileage driven, use cruise control etc. I read there was an extended warranty regarding this issue and my vehicle was or is affected.

My 2011 Hyundai Sonata (VIN [XXX] ) was brought to Gateway Hyundai in [XXX] for the mandatory P1326/KSDS engine recall inspection. I had a confirmed appointment on XXX at 7:30 AM. The dealership acknowledged the P1326 code and that the KSDS test was required.Instead of performing the recall, the dealership refused to inspect the vehicle. They contacted a third party who was not in possession of the vehicle and released the vehicle to that person without my authorization. The plates were removed and the vehicle was later sold without my consent. The recall was never performed and the engine defect was never inspected.This is a failure to perform a required safety recall and a violation of chain-of-custody procedures. A vehicle with a known engine failure risk was put back into public circulation without inspection. This creates a safety hazard for the public.I also suffered financial harm including $1,500 in towing, parts, labor, and storage fees. I have a signed tow invoice showing the VIN and the total amount paid.I am requesting that NHTSA investigate Gateway Hyundai’s handling of recall vehicles, review their authorization and release procedures, and take enforcement action if violations are found.

On my 2011 Hyundai Sonata GLS, both rear tail lights have melted to the point that the lightbulbs cannot be extracted and the brake and tail lights no longer work. When I looked into this, I found out this is a common issue on 2011 Hyundai Sonatas. It is almost always caused by excessive heat from the standard incandescent bulbs, which damages the wiring harness and deforms the plastic housing. When I called the closest Hyundai dealer (in Chico, California), they told me the warranty had expired last year and that I should have received a notice about it after I obtained ownership of the car in March 2025 (a little over a year ago). However, I did not receive a notice about this. Since the tail lights do not work properly as a result of this problem, it is a safety issue as it could cause an accident. It should be a recall repair instead of a warranty that expires. My car is still well under the 200,000 mile limit that was set on the extended warranty, but they're refusing to honor that because of the warranty being expired.

The vehicle’s airbag warning light is illuminated. The steering wheel also makes a clicking noise, which appears related to an internal clock spring/coil connector failure. This defect may prevent the driver airbag from deploying properly in a crash, creating a serious safety risk. I contacted O’Brien Hyundai of Normal on 4/23/2026 and was denied repair assistance solely due to vehicle mileage. The vehicle has been well maintained, and this issue involves a critical safety component that should not fail under normal use. I am submitting this complaint due to concerns about airbag system failure and occupant safety.

On March 18, 2026 I brought my vehicle to AutoNation Hyundai for an oil change and full diagnostic. Your dealership’s own diagnostic report showed no knock sensor code, no engine issues, and no active warning lights. My car was fully drivable when I dropped it off. Within 30 minutes of picking my vehicle up, the check engine light began blinking and the car became completely undrivable. It has not moved since March 20, 2026 at the dealership. The dealership did an additional diagnostic and found a knock sensor that was not there during the first diagnostics and have stated that my engine has too many miles to be covered uder warranty.

The contact owns a 2011 Hyundai Sonata. While driving at an undisclosed speed, the vehicle lost power, an alarm sounded for the braking system, and the vehicle went into LIMP Mode and the vehicle failed to exceed 15 MPH. After originally paying out-of-pocket for an ABS module at the dealer and was informed that the engine needed to be repaired and the brakes needed to be replaced. The vehicle was towed to the residence where an independent mechanic repaired the vehicle. There was a recall for the ABS module and the contact returned to the dealer, and the dealer confirmed that the independent mechanic had correctly installed the part. The dealer performed the official recall repair and refused to reimburse the contact for the previous expenses. Three months later, the braking system failed again. The contact stated that the vehicle temporarily returned to normal after a restart, but the failure worsened and required a return trip to the dealer for another repair. In January 2026, the failure recurred for a third time with a loud squealing sound. The dealer was not notified of the third failure. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 80,000.

The vehicle suddenly stopped and died while driving. The mechanic confirms that the engine is gone, contact Hyundai. Ourisman of Rockville and Hyundai Motor America (HMA) refuses to replace the engine for free. The vehicle has now developed a severe engine knock consistent with the well-documented defect affecting Hyundai’s Theta II engines. Hyundai has publicly acknowledged this issue and issued a major recall covering approximately 470,000 vehicles with the following specifications: • Model Years: 2011–2012 • Engines: 2.0L and 2.4L • Manufacturing Period: December 11, 2009 – April 12, 2012 Hyundai and federal regulators identified the safety concern as manufacturing debris that could restrict oil flow to rod bearings. This defect can lead to engine knocking and eventual engine failure. Critically, Hyundai has acknowledged that engine failure may stall the vehicle while driving, significantly increasing the risk of a crash. Hyundai’s official remedy for this defect required dealerships to: • Inspect engines for bearing noise • Replace the engine if necessary • Honor Hyundai’s extended engine warranty of 10 years / 120,000 miles for affected vehicles. This issue has also been the subject of significant litigation, including the class action lawsuit Case No. [XXX], filed January 23, 2018, against Hyundai Motor America (HMA), Kia Motors America, Inc. (KMA), Hyundai Motor Company (HMC), and Kia Motors Corporation (KMC). Despite these well-known issues, Ourisman of Rockville failed to disclose any of the following when selling my daughter's this vehicle: 1. The widespread engine defects associated with the 2011 Hyundai Sonata. 2. The recall and safety concerns related to debris restricting oil flow to rod bearings. 3. The extended Hyundai engine warranty covering affected vehicles up to 120,000 miles. This omission is particularly concerning because this defect presents a serious safety hazard and a clear and present danger.

Engine, Mar 16, 2026
My 2011 Hyundai Sonata experienced sudden engine failure and the engine is now locked up. The vehicle became inoperable and had to be taken to a Hyundai dealership. The dealership confirmed the engine is locked and not drivable. Hyundai denied the engine replacement claim stating the vehicle has A04/A08 branding indicating the engine originates from a scrapped or rebuilt vehicle. However, Hyundai refused to provide any documentation supporting this claim. They also refused to verify the engine serial number against the VIN to confirm whether the engine is original to the vehicle. A NMVTIS vehicle history report shows the title status as ACTIVE with no salvage, junk, or rebuilt branding. Despite this, Hyundai continues to deny the claim without documentation. This vehicle contains the Hyundai Theta II engine that has been the subject of recalls and settlement actions related to premature engine failure. The failure pattern in this case matches the known defect where engines seize or lock up unexpectedly.
