Selected complaints filed with NHTSA by 2012 Hyundai Sonata owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2012 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the driver's side seat belt unexpectedly detached. Several attempts were needed to secure the seat belt while driving. The contact stated that while the vehicle was parked, the driver's seat belt became inoperable and failed to latch properly. An independent mechanic was contacted. The vehicle was not diagnosed or repaired. The dealer was also contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 127,819.
My 2012 Hyundai Sonata (VIN: [redacted] ) experienced complete engine failure at 241,433 miles on August 7, 2025. The failure aligns with known safety defect symptoms described under NHTSA Recall Campaign 15V568000 and 17V226000, which cite premature bearing wear due to metal debris during engine manufacturing. My vehicle had previously received the knock sensor update under Campaign T3G and failed the BCT (bearing clearance test), confirming bearing damage. Despite this, Hyundai denied my engine replacement claim, stating the issue was related to a fuel pipe and not a rod bearing issue-this is contrary to their own recall documentation and dealer diagnosis. Hyundai continues to deny engine replacement, in violation of their federal recall obligations under 49 U.S.C. 30120. Their refusal endangers public safety by ignoring engine failures that can lead to stalling and crashes. …
Our 2012 Hyundai Sonata Limited had some kind of seat belt recall done in 2017. Not sure what as we were not given any documentation. We are having problems engaging the Driver's seat belt that started in the last month of 2022. Hyundai keeps referring us to the local dealer to see if indeed it is part of that recall. The local dealer insists on charging $160.00 inspection fee, if it's covered Hyundai will be charged. A knowledgeable mechanic should be able to sit in the driver's seat and attempt to buckle the belt and know if it is covered, without charging $160.00. Pease help.
The passenger side curtain and front airbags popped with no crash or reason, yes Hyundai will be able to inspect upon pick up. My safety risk was fortunately at minimal during times of explosion because I had just parked the vehicle when curtain side air bags went off first then slowly reserving when the front passenger side air bags went off good thing I wasn't on highway going highway speeds. The manufacturer said some one will reach out to me in 2 business days. No there were no warnings lights or anything
My seatbelt in the front seat does not work effectively. My airbag light is on Recall 169 ANCHOR PRETENSIONER INSPECTION is the recall I see that is associated with my seatbelt Recall 174 AIRBAG CONTROL UNIT Is the recall that I see associated with the airbag light Both recalls say they are completed. I called the Hyundai Dealership and they said reach out to the manufacturer because there are no open recalls on my car. Both are safety concerns that I hope can get addressed.
front Seat belts do not fasten properly and air bag light stays on. I don't see a pending recall, however did notice certain models recalled. This is a huge safety issue that is very concerning to me. I would appreciate if someone could get in touch with me to discuss further. Thank you. [redacted]; [redacted]
Driver's side seat belt frequently unlatches on own while driving vehicle. This places the driver at risk for significant harm should this occur during a collision. This problem has not been inspected or confirmed by the manufacturer or other professionals. The only warning lamp possibly associated with this is the airbag warning lamp.
My vehicle is experiencing several recall issues. The seat belt in driver seat randomly pops unlocked which is very dangerous while driving, the headlights and brakes lights go out once a month due to some electrical issues with the vehicle, the tire bearing clocks when the vehicle is turning
Seat belt doesn't latch properly. It's been happening for a while now. I have to fidget with the metal clip into the slot several times, and sometimes I just can't wear it at all because it doesn't latch.
It first started when the engine needed to be replaced, I spent thousands trying to get it repaired, soon after they fixed the engine everything started going wrong ( I truly think they put in a faulty or wrong engine @ Hyundai) the car was overheating, I would take it in they would say it's one thing pay thousands and it wasn't it, changed the coolant that goes into the cabin, there's always been a chemical smell since...still overheats, they said maybe it's the thermostat, spent more money still didn't fix it, the battery now won't stay charged(trunk battery) not sure if they hooked it up wrong...the seatbelt hasn't worked in years, I take it in they say it's fine, it never clicks, I have to click it in to the passenger seat for safety. They always say it's fine! …
