I recently purchased this 2020 Kia Soul at the end of April 2023. About 2 weeks ago while I was stopped for a red light in a busy intersection and the "restart" feature was engaged as I had the brake pedal pressed but then as the light turns green and I move my foot from brake to gas (that step is supposed to restart the engine) it did not start immediatley as it should have, Which left me in the lane of traffic vulnerable to possible accidents until it restarted. It finally started after what seemed to be forever and embarassment caused by the restart failure. This event could have had a different outcome if the car wouldn't have restarted. I am taking the car to the dealer tomorrow to have it inspected. I wasn't that there was even a problem until this happened there were no warning lights. …
The vehicle started with what felt like the car was going gently slower and faster as if it was almost out of fuel but had a full tank. This happened a couple times and I had the dealership check it out but they were unable to recreated the problem. This progress to a more obvious gear shifting harder or not when it should. There are times where when I try to accelerate, it shutters and doesn't want to go. I just recently had an issue after stopping for gas, where it lost power all together and started to almost redline. I pulled off to the side of the road and made several attempts to get going again and it would rev up but was not giving any power to the wheels. I shut off the vehicle and let it sit for a for moments and turned it back on and tried again and was able to get moving again. It didn't act up again until a few days later when I was heading to work. …
