2022 Hyundai Sonata: engine stalls while driving

Filed Jun 17, 2026 · Fuel system, Seats · TX

The vehicle’s fuel tank system failed catastrophically. The vehicle is currently grounded and has been inspected at the Hyundai dealership service center where it was towed. My safety and the safety of everyone on the road was put at extreme risk due to a severe fire and explosion hazard. Additionally, the defect caused the vehicle to suddenly lose power, sputter, and threaten to stall out while driving on a major interstate, creating an immediate risk of a high-speed rear-end collision. When attempting to add fuel, the pressurized tank forcefully spit gasoline back out of the filler neck, creating an active chemical and fire hazard at a public gas station. I was able to drive it home and called via Hyundai Roadside Assistance to have it towed to an authorized Hyundai dealership service department. On June 15th, 2026, the dealership service technicians officially confirmed the failure, stating that the fuel tank had expanded, the back floor base of the car was melting, and the vehicle was on the verge of exploding.

In November of 2024, I had a Check Engine Light for a Cylinder 2 misfire and a fuel to air mixture ratio. Had it towed to a Hyundai Dealership. Got a call the next day saying it was fixed. Picked the car up and 50 miles later it popped back up. Had it towed back again. They said my fuel injector was cracked. They had to order the fuel injector directly from Korea. Took 5 days to get the part and it installed. Fast forward to September 2025, Cylinder 2 misfire showed up again(same cylinder the fuel injector was replaced) and now the car shakes violently when accelerating and stalled at a stop light. Massive safety concern due to risk of an accident. Car to be towed to another dealership for the same issue less than a year apart.

First owner, sporadic acceleration problems reported from approx 6k miles. Documented with dealership.. “couldn’t reproduce” issue every time I brought it in after an occurrence. Dangerous when entering highway, as I never knew when it would fail/stall. Eventually broke down on busy interstate highway, replaced 1 fuel injector, and guilt tripped me into “needing” to have fuel injector cleaning because the others might fail as well. 27k miles was the first breakdown. 38k was the second breakdown and almost caused a serious accident when I was unable to accelerate. Replacing all 4 fuel injectors but not covering the oil change due to their faulty fuel injectors.

Car frequently stalls out when coming to a stop. Car has to be shut down and restarted in traffic. No warning lights and no OBDII codes. Dealership states they cannot find an issue and cannot reproduce symptoms.

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)

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.
