general problems of the 2010 Hyundai Sonata

Subject: non-collision engine compartment fire - 2010 Hyundai Sonata (VIN: 5npeu4af3ah630796) ?"on Dec 19 2025, my 2010 Hyundai Sonata suffered a sudden, non-collision fire that originated in the engine compartment. While there are currently no 'open' recalls on this VIN, I am formally reporting this incident as it matches the failure patterns documented in NHTSA defect petition dp18-003 regarding non-crash fires in Hyundai/kia vehicles. ?preliminary inspection of the damage shows characteristic signs of a manufacturer defect, specifically potentially related to a connecting rod bearing failure leading to an engine block puncture and oil ignition, or an electrical short in the abs module—both of which have been subjects of major Hyundai fire investigations and class-action settlements (e. G. , engine ii settlement).

Car has had check engine light on for 3 + years. Have taken it to several mechanics including a Hyundai dealership and none of them can figure out what is wrong. Have replaced water pump, belts x2 in a year (same belt) and thermostat x 3 again (all within 2 years). Dash fuel gage and dash heating/cooling gage are completely erratic. Cruise control does not work. Due to chronic check engine light and mechanics unable to pin point the problem, car has become hazardous to drive. With that in mind, today (9/10/2025) while exiting the high way, car stalled and behaved like it was in neutral. Steering wheel also locked up at this time. Luckily was able to stop. Had to restart car and then it occurred again while driving on a side street at 35mph. The codes that are still popping up are ones that I have spent thousands trying to fix and find the root cause of the problem. What could the issue be if no mechanic can seem to diagnose and fix the issue?.

While driving 60–70 mph on [xxx] just north of sylmar, I suddenly heard a loud, deep “pop” from the lower part of the car. Within seconds, the engine began steaming heavily and leaking oil everywhere. I immediately turned on my hazard lights and began maneuvering toward the right shoulder, crossing multiple lanes with semis and fast-moving traffic approaching behind me. I felt unsafe and feared the car could catch fire or explode, especially with smoke and oil present. After safely exiting the vehicle, a mechanic later told me the rod bearing blew and punched a hole through the bottom of the engine block, calling it a total engine failure. He said it would require a full replacement and matched known issues with this model. There was no warning before the failure. I’m having it inspected at Hyundai of downtown los angeles on July 28. I believe this event posed a serious safety hazard to me and others on the road. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I purchased a 2010 Hyundai Sonata in February 2022 from the original owner. In July of this year, my engine failed due to the oil consumption defect found in many of Hyundai's engines produced at the alabama factory. My oil and check engine light came on before it was time for my following oil change, despite making on-time synthetic oil changes during ownership. The vehicle hesitated and jerked on my commute to work, potentially causing harm to myself and other motorists. I went to take my vehicle to the mechanic on my lunch break. The car failed to turn over and has been inoperable ever since. I need my engine replaced at no charge. It's unconscionable that corporate would turn me away because the engine has 146k miles, which is nowhere near the industry standard 200k. Hyundai has inspected the vehicle and confirmed that an engine replacement is needed.

Recently at the Hyundai dealership in plantation,florida I had them repair 2 recalls which were the lamplight switch & crossmember. These recalls were not done correctly and caused my esc light to come on and my car shakes while driving. I never had these items before until they worked on my recalls. Now the Hyundai dealer service is refusing to fix the damage they caused. I need help right away. The recall repair appointment was on June 12, 2022 and had them check the recalls again on August 29, 2022. My car is still at the Hyundai service in plantation, florida.

Car has only 77,000 miles and was well maintained. On August 27, I had driven the car late afternoon, parked. Later after a couple of hours when I went to start it, it would not start, jump start did not work. Mechanic replaced the starter and still would not start. He checked the engine and told me that the engine has seized. I took it to the Hyundai dealer who confirmed that engine has seized. I contacted Hyundai as the complaint is similar to other car engines that seized when driven between 60,000 and 90,000 miles. Hyundai motors is not willing to fix this major issue.

Engine light was coming on took car to shop the engine light was on code po449 evap system fault failure in vapor canister housing performed diagnostic and pinpoint testing found said it needed canister close valve and canister easy the work was done but the engine light still comes on.

Car was running with no problems. Started up went down the street and it turned off on me all dash lights work. Mechanic said engine is siezed up. Car had oil no over heating or smoking. No warning of engine issue.

I have been having a problem with the engine light coming on for a while now and I have taken it to have it checked out, it has been put on the diagnostic machine to see what came up on the report. This has been done a number of times and whatever report shows up I have had it fixed but the engine light still would come on and it was suppose to be fixed, I would like some help in finding out why this problem continues this becoming costly and still not fixed could I please get some help with this. Would appreciate a response. Thanking you in advance yulanda johnson 2010 Hyundai Sonata. This problem has been going on for 1 year and 3 months without any kind of solution to the problem.

Starter failed. Car was exhibiting no problems. Parked at a store. Came out and wouldn't start. Battery was not a problem. Had to have car towed. Needed a new starter at 75,621 miles. Keffer Hyundai svc ctr stated they have had complaints, even issued statement to other automotive repair shops of what to look for should cars be brought to them for service (ours was). Keffer svc ctr further stated they "should probably issue recall".

Delays in acceleration linked to a computer program that controls the transmission, shifting from 1st to 2nd gear automatic transmission, there may be a 2 to 3 second lag in acceleration due to the transmission control module programming or transmission.
