My car has been acting up almost every winter. Bought brand new and within two years would not start. Triple A had to get it started. Next winter it shook and the check engine light came on. There was a misfire. I called Kia of Queensbury and they just told me to keep the gas cap off for a bit and than drive it after putting it back on. I believe the fuel injectors were a problem at that point because at times when starting it would shake and it would lag in power. The check engine light did go off but it kept lagging and I had to put fuel in it more often. They did not diagnose it. The next winter it shook and felt like it was going to shut down. I took it in for diagnosis while it was under warranty. They denied anything was wrong. This winter it did it again. It shook and the check engine light came on. Even though I told Kia service in Queensbury NY that a computer said there was a misfire in cylinder 4 they insisted that if the check engine light was not flashing I could drive it. They wanted me to wait almost two weeks to get it diagnosed. Had I driven it as they stated I could have ruined the engine, it could have caused a fire or for me to have an accident. I called back told them it was shaking and dangerous to drive. They allowed me to take it in earlier. I had it towed in. Now that it is out of warranty and 64000 miles they admitted the fuel injectors had to be replaced and the spark plugs. Because of the issues I had experienced from the beginning, I believe the fuel injectors had been faulty for a long time and could have been a serious risk for myself and other drivers. It was dangerous. The fuel injectors and spark plugs have since been replaced out of pocket. I asked for the fuel injectors and spark plugs that were taken out of my vehicle to be given to me, but the service department did not comply with my request.
The contact owns a 2020 Kia Soul. The contact stated while driving 30-35 MPH, the check engine warning light illuminated. The vehicle was taken to the dealer where the fuel injectors were replaced; however, the failure later reoccurred while refueling the vehicle. The vehicle was taken to a second dealer Gunther Kia (1900 S State Rd 7, Fort Lauderdale, FL 33317) on four different occasions where the spark plugs were replaced and the fuel tank was drained; however, the failure persisted. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 90.
