2022 Hyundai Sonata Complaints

ELECTRICAL SYSTEM — Filed 08/20/2026

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.

FUEL/PROPULSION SYSTEM — Filed 06/02/2026

RECALL REMEDY FAILURE AND MANUFACTURER COERCION My Certified Pre-Owned 2022 Hyundai Sonata Limited has been held completely out of service at an authorized Hyundai facility since June 2, 2026, due to severe fuel tank expansion under active NHTSA Safety Recall 25V-796 (Hyundai Campaign 286).The dealership confirmed that the defective expanding plastic fuel tank ballooned with enough force to structurally warp and buckle the unibody center floor pan and frame rails. Rather than providing a safe, timely remedy under federal recall guidelines, Hyundai Corporate and the dealership are attempting to coerce me into an unfair, non-statutory "voluntary trade-in" that simply pays off my remaining loan balance ($22,000) while completely wiping out the $9,000 in cash equity ($3,000 down payment and $6,000 in monthly payments) I have invested into the car. Upon rejecting this predatory trade-in offer, the manufacturer immediately threatened an additional 6 to 8-week delay to attempt a massive structural frame and unibody pull, which would bring the total out-of-service time to over 90 to 110 cumulative days. Furthermore, the dealership is actively withholding the internal diagnostic write-ups and structural alignment prints from me. I am requesting that the NHTSA investigate this recall remedy failure. Hyundai is using extreme delays (90+ days) and structural frame threats to force consumers to abandon their financial equity rather than issuing lawful, purchase-price repurchases for vehicles deemed structurally unsafe due to a manufacturing defect. I can't provide any documents as they have refused being able to provide me with any. Was told I would be emailed a copy from the dealership several times and they never end up sending over any information.

SEATS — Filed 06/16/2023

The driver's power seat drive cable on the left-hand track rail snapped internally. The motor only advances the right side, causing the seat to twist violently to the left and jam. This mechanical failure occurred prematurely at 9,000 miles. Because the seat framework is structurally compromised and twisting out of alignment, it poses a severe occupant safety hazard in a collision. And interferes with positioning the seat to operate the vehicle safely. The dealer has inspected the complaint and was able to reproduce the complaint. But did not cover it under warranty. There where no warning signs before the premature failure.

STRUCTURE — Filed 07/26/2026

The contact owns a 2022 Hyundai Sonata. The contact stated that while driving approximately 65 MPH, there was an abnormally loud bang coming from the vehicle. Upon inspection, the contact became aware that the sunroof windshield visor had shattered. The vehicle was taken to a local dealer where it remained for further inspection. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 61,000.

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.

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.

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.

VEHICLE SPEED CONTROL — Filed 06/04/2024

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

I was driving down the street and I hit a car because I felt that I lost the control of the car momentarily and it happened as it is described on this recall - 22V746000: The vehicle's "fail-safe" limited-mobility drive mode may be impaired, when prompted by a transmission oil pump malfunction, which can result in a complete loss of drive power. As a result the car crashed into another vehicle. Have the car since 24th of March. Have been feeling at times that I fight to be the driver with the car. Spoke to friends about the issue and they were concerned about that too.
