Suspension noise over bumps

I am reporting a serious and ongoing safety issue involving my 2023 Kia Forte GT. The vehicle has experienced persistent mechanical problems, including a check engine light and multiple diagnostic trouble codes, including P0420 (catalyst system efficiency below threshold – Bank 1), P0300 (random/multiple cylinder misfire), P0304 (cylinder 4 misfire), and P0301 (cylinder 1 misfire). These codes have appeared as stored, pending, and permanent, indicating ongoing and unresolved engine and emissions system issues. In addition to these mechanical problems, the vehicle is emitting strong and concerning chemical fumes into the cabin during operation. These fumes are noticeable while driving and create a hazardous environment for occupants, raising concerns of toxic exposure and making the vehicle unsafe to operate. The vehicle also exhibits drivability issues, including jerking and performance irregularities when accelerating. Despite multiple attempts to have the vehicle diagnosed and repaired under warranty at authorized Kia dealerships, including All Star Kia East and All Star Kia Seigen Lane, the dealerships have refused to properly diagnose or repair the vehicle. I have been informed that my vehicle or account is “flagged in all systems,” and service has been denied on that basis. The refusal to address an emissions-related defect, combined with active misfires and the presence of chemical fumes entering the cabin, presents a serious safety risk. I am requesting that this issue be investigated as a potential safety defect affecting this vehicle.

The front driver side door is ‘popping’ open while driving. In addition, the seatbelt randomly releases while driving.

My son, [XXX] , has opened a complaint/Case #XXX with Kia. His 2023 KIA Forte had been idle for at least 24 hours when the engine compartment caught fire. He became aware of this when the Fire Department knocked on his apartment door around 4:00 PM 12/26/25 and said they were evacuating the building because a car was on fire. He went outside and was shocked, to say the least, that it was his car. The Fire Department had taken off the hood to extinguish the fire. He removed his belongings once the fire was out. He contacted his insurance company but since it was a holiday weekend, he did not get a call back until 12/29/25. He then filed a claim with State Farm Insurance which was required to get his car towed to a Kia repair location. On 1/9/25, [XXX] [XXX] t Castrucci Auto Shop in [XXX] [XXX] he car was totaled. I talked with [XXX] who was [XXX] between the auto shop and State Farm, told me that once the repair exceeded the value of the car, he was instructed by State Farm it was totaled and there was no need to continue. On or around 3/4/26, Kia sent engineers to assess the damaged vehicle. Kia determined it was an engine fire and the cause was undetermined due to the condition of the engine department.

My car suddenly accelerated while I was pulling into my canopy carport causing me to crash into an old basketball goal and then the wall of my cottage. When this happened I was slowly pulling in to park when the car suddenly accelerated on its own and kept moving forward despite me pressing the brake. The RPM gauge continued to rev after the impact and the only way that I was able to make it stop was by putting the car into park and pushing the button to turn the car off. No warning lights illuminated on my dash. I have video of the incident from my security camera in my backyard.
