Fuel/propulsion system
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…

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.

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…

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.
