    I went to the Garden Grove Kia to get my new 2016 kia optima repaired for their knock sensor settlement repair. By their own terms of the agreement all original and subsequent ow ers can get vehicles repaired. They took my vehicle information, I gave them all details of my ownership of the vehicle and they said they would fix it. The next day I rented a trailer to take the vehicle to get repaired (vehicle still runs but don't think it's safe to drive like that) and upon arriving, a worker comes out and tells me that they will not repir the vehicle because I just purchased the vehicle. Craig, the manager, also refused to see ownership documents but gave me 2 things; legal advice saying that I should sue where I bought the vehicle from and a paper that said they will not fix cars owned by dealers and auctions. I am neither am neither nor. Craig, also stated that Kia wont cover the repairs.

    The check engine light came on in the car. Upon having it checked at a local automotive shop, we discovered that the thermostat assembly is malfunctioning. This can cause the engine to overheat and shut off at any time which of course would be a severe danger. Additionally, a bad thermostat assembly in Kia vehicles can lead to engine overheating or overcooling, potentially causing engine damage and even a fire risk. Upon searching, this appears to be a common issue with the 2016 Kia Optima.

    Valve 3 does not have compression sent to private mechanic. Sent to KIA was told this is not covered under warranty for new engines went to say that intrest rates are down for new used cars. After some research this could be caused by engine recall.

    The car caught on fire while I was driving. No warning lights came on and the car didn't show it was running hot. I tried to engage the brakes, and they malfunctioned. I coasted the car to the side of the highway, where the fire and smoke plumed from under the car. I immediately exited the car and ran. As I was running from the car the grass was on fire. The car was totally destroyed by fire. The car has not been inspected by my insurance or Kia. Kia has a class action settlement for car fires the year, make, and model of mine.
