Appropriately April 2024, The engine service light came on at about 115,000 miles, followed by the 2020 Kia Soul X-line engine stopped running. I tried turning off the key and attempting to restart the car however it would start but for only a few seconds. After 5 or 6 tries to restart the car, I finally turned off the car, waited about 3 minutes and then restarted the car in as it continued to run. The check engine light remained on but I noticed that there was a drop in power when I tried to accelerate. Since then I have notice the engine check light go on and off several times. I recently brought my car in to have an oil change only to find out that there was no oil on the dipstick. I signed a form stating this and got the oil change completed. …

Car subject to theft SEE NHSTA press release Feb. 14, 2003 The press release announced a fix had already been achieved (EMPHASIS ADDED): Hyundai and Kia HAVE developed theft deterrent software for millions of their vehicles that lack an immobilizer and will provide it FREE of charge to vehicle owners Unless your PIO totally muffed, this has been an EXTREMELY SLOW ROLLOUT. Two local dealers deny having any information about by vehicle from Kia. The Kia consumer line is jammed and I have not received any callbacks. Now I have gotten a a threatening letter from my insurer. Get on Kia's ass. This is a safety issue.

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. …
Our vehicle experienced every dash light on the board coming on intermittently. At time, we could not use the remote control and had to open the door and crank the car manually. Windshield Wipers and headlamps did not work, nor did any of the safety features on the car or indicator lights. When all illuminated, we took the vehicle to local Kia dealership and eventually they replaced the electrical panel. The side and rear collision indicators never worked again even after repairs were done. The car continued to display every light on the dash after the electrical panel was replaced and local dealership could not fix it. None of the indicator lights showed problems with the engine and regular maintenance to the vehicle was maintained on schedule. Four years into the life of the vehicle, the car started burning all the oil in the engine and oil indicator light did not come on. …
Complaint Regarding Mechanical Failure and $315 Service Charge on Recent Vehicle Purchase I'm writing to formally express my concern and disappointment regarding the recent service experience involving my vehicle purchased on April 12, 2025. A few weeks after purchase, I returned to the dealership with concerns over a check engine light. I was reassured by your service department that nothing was wrong with the vehicle. However, the car recently died while I was driving on the highway, putting me in an unsafe situation and requiring a tow. Now I am being told that spark plugs need to be replaced before further diagnosis can occur, and that I am responsible for a $315 charge. The technician noted that cylinder 2's spark plug was loose and melted-an issue that clearly could have caused the breakdown. This is not typical wear and tear. …
The vehicle has experienced intermittent stalling and near-stalling while driving. The problem began after a prior Kia engine replacement related to DTC P1327/P132700. After the engine replacement, the vehicle developed additional drivability and warning-light concerns, including P0420 and communication/CAN faults. An authorized Kia dealer later documented that the vehicle had stalled a few times, identified P0420, reported a clogged catalytic converter, and found 11 additional lost-communication/CAN-related codes. The dealer stated that approximately eight additional diagnostic labor hours would be required to investigate the remaining faults. The vehicle was returned with the intermittent stalling condition unresolved. The stalling presents a safety risk because the vehicle can lose motive power unexpectedly while being driven. The vehicle remains available for inspection. …

The contact stated that the front windshield wipers failed to work intermittently. The contact took the vehicle to the local dealer; however, the mechanic was unable to duplicate the failure. The failure persisted. The manufacturer had been informed of the failure. The failure mileage was unknown.
I purchased this car (Used) on 8/1/2023 and on 8/7/23 I called Kia and stated that the car started shaking while driving and I took the car to the dealership on 8/10 and they stated they could not find any problem, they would have if they had taken it out for a drive. After waiting all day from 9:30 until 4pm they found nothing. I saw my car just sitting there and no one doing any work or anything on my car. My car still shakes so bad while driving that even the steering wheel is shaking and now when I stop at a red light the car takes a few minutes before it will move. I have had this car for a month and 2 weeks and they will not return my calls to setup an appointment. Kia Corporate can't even get them to respond. What can I do to get help with this. I am even afraid to drive this car (2020 Kia Soul). I need some advice on what I need to do. HELP
