“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.

“The fuel tank assembly became pressurized with compressed air due top worn purge control system check valve. This caused the tank to deform and the deformation of the tank led to the fuel pump being pushed out and the back seat of the car was completely unattached and no longer secured. There was a strong presence of gas smell in the car as well. The check engine light came on and the car began to drive poorly. It was taken directly to a Hyundai dealership where it remains as of today. This could have resulted in the car catching on fire and potentially killing everyone in the car. My [XXX] daughter and 2 friends was driving the car from Louisiana to Mississippi when this occurred. The dealership in MS told her she needed to call and find someone to come and get her because the car was not safe to drive. My daughter was stranded in another state and had a college friend come and get them since I did not have a car and I was in Louisiana. After several hours her friend was able to pick them up which she remained stranded in MS for an additional 4 days. I had to get a friend to meet them halfway and bring her home because the dealership said there was nothing…”

“The passenger compartment climate control blower motor circuit suffered a severe thermal overload. The terminal overheated, shorted out, and physically melted the primary engine wiring harness (Part #91400-L0051) inside the main fuse block connector housing while the vehicle was operating. This caused an immediate smoke/fire hazard in the cabin and a total loss of window defogging and climate control functionality. This structural breakdown is directly tied to the electrical failures documented in Hyundai TSB #WTY037 / 25-EE-002H.”

“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…”

“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.”
