2022 Hyundai Sonata Engine Problems

The engine on a 2022 Hyundai Sonata developed rod knock at approximately 99,460 miles. The vehicle had been serviced exclusively at an authorized Hyundai dealership for its entire life with 12 documented service visits. What failed: The engine lubrication system. Two prior events at the dealership are documented in the service records: (1) approximately 20,000 miles before the rod knock, a dealership technician damaged the oil filter cap during a service visit, causing an active engine oil leak while the vehicle was being driven. The dealership repaired this at no charge, indicating fault. (2) The dealership placed an oil change reminder sticker in the vehicle specifying an interval that their own service advisor later acknowledged was set incorrectly. The vehicle was brought in approximately 660 miles past that sticker date. Safety risk: Rod knock indicates internal engine bearing failure. The engine continued to be driven at the dealership's instruction ("keep driving, come back if you hear it again") with unresolved internal damage. The knocking sound has since returned, creating risk of sudden engine failure while in operation. Confirmed by dealer: Yes. The rod knock was confirmed by the dealership's technician on the date of the diagnostic visit. The diagnosis noted the engine was low on oil and recommended an oil change, but no repair was performed. Warning lamps/prior symptoms: The engine oil warning light illuminated during the prior oil filter cap leak incident. At the rod knock visit, the knocking sound was the presenting symptom. No oil pressure warning light was noted at that visit. Inspection status: Inspected by authorized Hyundai dealership. Warranty claim was denied by dealership and no response has been received from Hyundai Motor America after formal escalation.

Our 2022 Hyundai Sonata experienced multiple issues related to recalls affecting the vehicle’s reliability and operation. Due to these ongoing problems, the vehicle was taken to a dealership and has remained out of service and in dealership possession for approximately 90 days. The issues were confirmed by the dealership, and Hyundai Motor America was involved in the case. As a result, Hyundai approved a full buyback of the vehicle, indicating the problems could not be resolved in a reasonable timeframe. Despite this, the vehicle remains out of service and unusable. Hyundai has failed to complete the buyback process and has not provided a resolution within a reasonable time. There have been repeated delays and missed timelines. The extended period without a functioning vehicle creates reliability concerns and potential safety risks, as the vehicle could not be safely depended on for regular use prior to being removed from service. The vehicle is currently still in dealership possession and unavailable for use.

While driving around 20 mph my cars rpms will rev and my car will take off then my automatic breaks will kick on and today around [XXX] I was going under 25 mph and there was a car in-front of me and it really scared me as I went to hit the breaks my car already did. My car has done this twice now, both on residential roads. The first time I figured it could have been a me error but now I know this is something seriously wrong with my vehicle. I have had my car for years and I know my car and it never just takes off how it has been there’s always a delay when I go to accelerate. This is very concerning and I’m scared to drive my car now.

Driving on the highway ih35N at 75 mph, my car's engine randomly started violently jerking and then shut off and wouldn't start back up. Had it towed to Hyundai (2022 Hyundai Sonata ~33k miles) took a few days but they repaired it under warranty saying it was bad fuel injectors and they replaced all 4. My car just dying on the highway could of caused a bad accident at that speed. Moving to present day (June 28th, 2025) car is at 56,400 miles and its starting to jerk at low speeds and is getting terrible gas mileage again. I'm taking it back in as I am still under warranty but everything points to fuel injectors again. Only warning lights I get was when the car died on the highway. Just a check engine light.

My car has been experiencing air defects when it would randomly stop working. Last month my car air stopped working after I picked my pet up from the groomers and all together on the service road my car shut down. After being towed to Hyundai dealership I was being demanded that I ride on E and that it could’ve been my fuel injector. After realizing it was not that they claimed it was a failed fuel pump. After paying and recording my car back not even 8 hours later my car would not turn over again with no air causing me to get towed a second time. The dealership couldn’t diagnose what’s wrong with my car so they tried to throw false accusations as to my old gas can that stays in my truck that the smell of gas is the reason why they can’t properly diagnose my car. After getting my car back and driving it home, after turning it off and back in case duplicated the same problems with me. Wouldn’t turn over or produce air. Dealership refuse to comment on the paperwork if the problems they ran into but rather called me. After keeping my car a week to drive it the problem didn’t duplicate. I’ve had my car for about 3 weeks now and the air still give me problems and don’t want to come on every now And then

I leased my brand new Sonata at the end of August in 2022. in November 2022 I was driving on the highway and my vehicle started to decelerate. I stepped on the gas pedal and it just went slow and slower. I was able to make it home but after shutting the car off it would not start again. I had it towed to my dealer and they fixed something with fuel injection. in February 2023 the same thing happened with only 4500 miles on the car except this time my car decelerated so badly I pulled to the side of the road and it immediately died. I had the car towed again and they fixed it again. The car was good for a while but on [XXX] of 2024 the deceleration issue happened again. it did not stall out on me and I was lucky enough to be able to get the car to my dealer to have them do a diagnostic check. They did not find anything. This is baffling to me. I guess I need to break down again for, something to be fixed with this car. my complaint is that while driving my car and if I break down it is unsafe for me and other cars on the road if my vehicle just dies. I do have a job and also like to travel out of town sometimes. I do not feel safe with this car. It broke down twice in the first year so it did not qualify for the lemon law in my state of Pennsylvania. Please provide some information on what I need to do to keep myself and other drivers safe. Thank you very much. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While I was driving the vehicle late last year (2022) I pulled out of the parking lot of my office and my vehicle did not accelerate even though I was pressing the gas pedal. I pulled over, turned off the car, restarted the car, and everything was normal again. This morning (8/15/23) as my wife was driving my son to school, the car did the same thing and the vehicle did not accelerate even though the gas pedal was pressed and the RPM's were registering but there was no drive power. She had to pull over and restart the car as well.

My 2022 hyundai sonata sel completely shuts down while driving, most recently it happened twice in the middle of an intersection when I was trying to make a left turn it is very very scary and dangerous. I purchased the vehicle in July 2022 and since then it has had consistent idling issues meaning if it's parked too long it will just turn off but now it is turning into while I'm actually driving at the engine dies and again recently it's been in the middle of intersections which is very scary. My check engine light came on it only 4000 miles on new car - very concerning. I encourage anyone having intermittent engine stalling in any way to make sure we are reporting this.

Our 2022 Hyundai Sonata completely shuts down while driving. We purchased the vehicle in May 2022 and since then it has died over 10 times and has almost caused multiple accidents. We have 3 video footage that we have shown Hyundai corporate and the dealership service technicians. They drive the vehicle a few miles and give it back unable to duplicate it. Hyundai refuses to buyback the vehicle due to safety concerns. We do not know what more we can do and have been working on this since August. We no longer drive this vehicle as it is too dangerous and will eventually cause an accident.

On multiple occasions, the car has intermittent acceleration issues and hesitates when the automatic transmission is shifting to the next gear. Without warning, the car completely turned off - engine failed - while driving and in the middle of making a turn, and luckily oncoming traffic stopped in time before we were in an accident. The local dealer has been unable to replicate the problem; however, there is an open recall on the same make and model but my VIN is not currently included in this recall. This is not a coincidence and this vehicle is not safe to drive. I also already contacted Hyundai directly but the case manager has yet to resolve the issue, just says the VIN is not part of the recall.
