What 88 owners told NHTSA about the 2022 Hyundai Sonata Hev

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.

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.

2022 Hyundai Sonata N Line, VIN [XXX] , purchased August 15, 2025 with low mileage under original manufacturer warranty. Within 3 months, recurring transmission and drivability failures began. Six repair visits since November 2025; 71+ cumulative days out of service within 8 months. Visit 1 (11/24/25, 14,748 mi): Hesitation/failure to accelerate from stop. Could not duplicate. Visit 2 (12/4/25, 14,800 mi): Same concern. Fault codes found; auxiliary pump and relay replaced. Visit 3 (1/19/26, 15,982 mi): Check engine light, jerking. External oil pump leaking; replacement required. Visit 4 (1/30/26, 16,025 mi): Check engine light. TCU update, DCT learning performed; declared resolved. Visit 5 (2/19/26, 16,119 mi): Check engine light returned. Transmission oil pump failed; replaced. Visit 6 (4/14/26, 16,945 mi — OPEN 44+ days): Post-repair lurching, infotainment failure, ongoing jerking. On 5/28/26, the service manager at McDonough Hyundai (McDonough, GA) stated the vehicle likely requires a complete transmission replacement and disclosed approximately 4 additional vehicles at the same dealership with identical unresolved issues. Hyundai Motor America refuses to authorize repairs or Techline escalation unless the dealership confirms the intermittent concern — a structural barrier that prevents warranty resolution. Safety concern: repeated failure to accelerate normally from a stop creates direct risk of rear-end collision or inability to clear intersections.

The cars fan is constantly running even when the car is cool. I think it has to do with the ITMS I contacted the dealer and they said there’s nothing they can do about it this happens every time the vehicle is started even when I am parked. The fan is constantly running at 100%.

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.

I brought this car 2022 Hyundai Sonata with 41k miles on it and only had it for 6 months. It has cut off 3x so far after putting gas in the tank. Always the same thing, oh nothing is wrong. Obviously there is and I see there is a recall on this car however my VIN isn’t coming up as a recall. This has to be fixed.

I purchased the car new and three times since then, the latest last week, the automatic brakes kicked in briefly for no apparent reason. I feel that if a vehicle would have been directly behind me this could very well have caused an accident. Each time it happened it was during daylight and fair weather although I can't remember if the sun was shinning. After the second time it happened I reported it to the dealer and they said they had no recalls on it and no explanation but if it happened again I should record all circumstances to investigate the cause. A couple years went by and it didn't happen again until last week. Now the warranty has expired on my car. No one has inspected my car; It has driven fine except for when the automatic braking problem occurs. There were no warning or indicator lights that I noticed at the time.

My windshield cracked with no discernable impact or reason. The windshields for the vehicle are too thin for use on a highway and crack too easily. This puts my safety and the safety of others at risk, as well as affecting safety mechanisms related to or mounted to the windshield. It has been replicated by myself as it's happened twice in the last 4 months of owning the car. The first windshield was replaced by my dealer at Laird Noller in Topeka.

I was pulling into a parking space at my church, same place I routinely parked. I was moving forward slowly with foot on brake alternating lifting foot to move forward until I was all the way in. As I lifted my foot from the brake, the car suddenly accelerated forward, going over the cement parking block, on to the grass and sidewalk before it stopped. Two metal handrails along the steps into the larger parking lot. Fortunately, no one was hit or injured, including myself. The result was major damage of the left side. Aside from the exterior, the car worked as it always has. I reported the collision to my insurance company, State Farm, and they directed me to a Hyundai repair shop. I know the fault was not mine for 3 reasons: 1) Once I turn into a spot to park, I always move slow, using the method mentioned above. I never use the gas pedal once I'm facing straight in the parking space; 2) My word would, of course, not be enough to relieve me of the responsibility for what happened. However, if I had stepped on the gas, though I know I didn't, the car would not be able to go from just stopping its forward move to the sudden and very fast acceleration that normally would require several seconds to reach that speed; and, 3) This was the 2nd time sudden acceleration happened, the 1st time was in June 2024 during a 3-point turn on a residential street. I completed the turn, ready to go forward, when the car suddenly and rapidly accelerated, jumping a curb and hitting a fire hydrant. My left front grill sustained damage, but since the car worked well, I did not report this to State Farm, waiting until I was willing to pay the deductible. This 2nd episode had me researching the Internet to see if there were others who experienced sudden accelerating with resulting fatalities. I believe my car has a defect and gives no warning when it will occur. My driving record is excellent. I don't speed and I drive defensively. My 2 brothers and 2 male in-laws said I'm a good driver

My 2022 Hyundai sonata hybrid started blowing white smoke from the exhaust. Took it to the dealership and was advised the valve that controls antifreeze failed and leaking antifreeze in exhaust. This caused the engine to overheat and would cause the engine to blow up. My car has 83,000 and was told the manufacturer warranty only covered to 80,000 and extended warranty would not cover the part. Was told it would cost 2659 to fix. This is part of the hybrid power train and should be covered under the 100,000 Hyundai warranty. I have seen the same issue with other sonata hybrids on the internet that is doing the same as mine. Hyundai needs to recall for this since it is a needed component for the engine.

My 2022 Sonata has had to have its fuel injectors replaced two times in the 3 years I've had it. On 12/18/2025 My car started to become very slow and could not reach over 20mph, and started to smell like gasoline and shake slightly. I had to get it towed to the hyundai dealership and there they told me that the fuel injectors need replacing. I had the same exact problem with this car before where I had to get the car towed to hyundai and then they had to replace the fuel injector.

I was driving the car home from Massachusetts when, after 6 hours of driving, the car started to shake and would not accelerate. It was also emitting a burning smell. I exited the highway and called for a tow truck. I was told by the Hyundai dealership that, at 4,100 miles, a fuel injector and high pressure rail had failed.

Initially vehicle battery is drained after three days of sitting in driveway and not being used. Vehicle has been taken in to dealership in July 2025 and found the 12v integrated battery was faulty and was replaced after being on backorder for three weeks. After battery was replaced the vehicle battery is drained after five days of sitting in driveway and not being used. No lights are left on, no aftermarket accessories are plugged in or attached to the electrical system. This has been an ongoing issue and the dealership I initially worked with has now had my car 3 different times and over four weeks and have stopped returning my phone calls. I have just sent my car do a different dealership and have been told it may take up to 2 months to diagnose the issue. I cannot open the door or start the car without using the emergency key, when I gain access to the car the 12v battery reset button rarely works to power the vehicle again. This is something that the dealerships are aware of, but have no idea what the actual problem is. Please for the love of God help.

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.
