The contact owns a 2017 kia Forte. The contact stated while making a stop the vehicle stall, but the vehicle continued to operate normally. The vehicle was taken to a mechanic who replaced the fuel pump, but the failure occurred several times. At a different occasion the vehicle stalled and shut down completely and the vehicle would not start. The vehicle was towed to a repair stop where they replaced the vapor canister purge valve and the canister solenoid, but it did not repair the vehicle, so the vehicle was towed to a kia dealer where they did a fuel injector service and clear codes and a transmission fluid flush on the vehicle, but the failure reoccurred, and the dealer was not sure what the failure was. The manufacturer was not contacted. The failure mileage was 94,777.

Our 2010 kia Forte ex lost 90% of power repeatedly (rpms drop to idle, regardless of throttle position) at speeds from 0-35mph. This is not the first occurrence, but I think it is the same problem. This is very dangerous if you are making a left turn and you lose acceleration, you can be in the way of oncoming traffic by losing power. About 2 years ago (25,000 miles or so) the tps (throttle position sensor) went out. Kia could not diagnose it until it threw a code (lame). Now we get the same issue, the vehicle is stalling, or "stumbling" when the speed should be constant or accelerating, but there is no engine code for the code reader to pickup yet, so the mechanics can't figure out what to do. Apparently this is a problem on many models of kia/Hyundai and the mechanics don't recognize it so they can't fix it, and you are stuck with a dangerous condition. I think there should be a recall of these faulty tps sensors. Kia/Hyundai should at least issue a safety TSB (technical service bulletin) to clue in their mechanics as to what the problem is. .
