2022 Hyundai Sonata Complaints

ENGINE — Filed 05/31/2025

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.

POWER TRAIN,ELECTRICAL SYSTEM — Filed 11/24/2025

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.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER — Filed 05/14/2026

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%.

ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM — Filed 02/07/2026

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.

FUEL/PROPULSION SYSTEM — Filed 12/23/2025

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.

FORWARD COLLISION AVOIDANCE — Filed 03/09/2026

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.
