I parked the vehicle in an outdoor parking lot and the vehicle remained parked and turned off for approximately four hours. At approximately 9am, I was notified that my vehicle was smoking. A person who was walking past the vehicle observed the smoke, obtained a fire extinguisher, and extinguished the fire. The fire department subsequently responded, disconnected the vehicle battery, and opened the rear of the vehicle to ventilate it. The fire and resulting heat damage were concentrated on the driver's side rear of the vehicle, directly behind the driver's-side rear tire and in the area of the rear bumper. The plastic at the base of the bumper melted, and melted bumper material was observed dripping onto the ground. The responding fire marshal inspected the vehicle and indicated that the electrical box located in this area may be associated with the origin of the fire. Wiring from this area runs to a…”

Hyundai covered this under warranty, but the cost was $8,000. - In early spring 2025, all coil packs had to be replaced due to misfires, costing approximately $500. - September 4, 2025, The car stalled while I was driving on a main road and I had to pull over. There were no warning lights and I started home. About a mile from home check engine light came on so contact mechanic. Ended up towing to a dealership and was told the engine must be replaced because the oil had burned off without any warning from the oil light indicator. The turbo also needs replacement. - The combined cost is $14,000. These…”

“Continuous issue of front driver passenger power seat front level button failure. Continuous Headlights, fog lights getting fused every 4 months. Indoor back roof light works and sometime just does not work for months.”

“For the past month my car has been stalling in traffic. The car stalls and then turns back on a few seconds later. It also stalls when I am accelerating after stopping for a red light. This situation is very dangerous and it means that I cannot drive my car expecting to be safe at all. It seems like the motor and the transmission are involved which makes the stalling very dangerous as those are major systems.”
