Motor will not turn over, starter/electrical failure.

Filed Mar 3, 2026 · Electrical · CA

The car has completely shutdown on 3 separate occasions. It wouldn't start and all the electrical did not work. It started the next day. All this in a span of 5 out of the 8 months we purchased it. The last time, we found the fuse box was burnt when the tow truck showed up to take it to the dealership. The dealership is trying to blame us because we changed the battery after the second time and not honoring the warranty. They are trying to charge us $18,000. The car had already shut down two times before we even changed the battery. We contacted Kia corporate and nothing has been done, but just phone call saying they will call us back after they talk to the dealership. I got so scared for my wife because she was the one driving the car. This is such a dangerous problem with the fuse box. I researched car problems with Kia Sorentos and sure enough other Sorentos have been recalled, but not ours.

My 2021 KIA Sorento, has literally cut off on me several times in the last 3 three months, when I am at a stop ight/sign the vehicle will just shut off, it will not turn back on, after 3-4 attempts of trying to get the vehicle to start it would, but later on the same day it would do the same thing. On the third incident I took the vehicle to the Kia dealership in Victorville, Ca. After keeping the vehicle for several days, they said they could not find anything wrong and that i should replace the battery because it had a low cell. So I bought the battery and paid for the diagnostic. the same day I picked of the vehicle drove to Las Vegas , Nevada, the vehicle did the same thing it would not start, we had to get a jump to get it started, was terrified to drive the vehicle back to California. Call the dealership about the issue but never received a call back. Now here it [XXX], the vehicle cuts off at a 4 way stop light, we were in the turning lane!!!! the vehicle would not start, there virtually no power, had to move the vehicle to a parking lot around the corner, called a tow truck and had the vehicle towed to the Kia dealership. They are saying it will take 3-5 days before they can get a diagnosis done. There is something going on with this vehicle, and I do not feel safe driving it even a short distance. This problem needs to be investigated before some get hurt/accident. I have not a seen a recall on my VIN number but there is something on wrong very similar to the transmission problems the Kia is having. I would like to have this issued looked at immediately to find out the root cause of this problem with a resolution. Will be awaiting a response, my vehicle is still at Valley Hi Kia, Victorville, Ca INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Transmission has to be replaced. Car shut off, redlined when gears switched, struggled between gear shifts, would not start.

In 2 instances the car shut off without warning. Once After the car had been shut off, ( would not restart.) Then again while the car was in drive sitting at a red light. (Engine shut off without warning). Dealership could not figure out cause. When trying to restart the dash lights would come on with all codes being thrown as failure for multiple systems but engine would not start or try to start. The car did think it was running though as the dash would say car will shut off in alloted time frame that was set in car settings. Both times after the car being towed to the dealership and sitting for the night it started back up next morning like nothing ever happened. I ended up getting traded out of the vehicle at 18,500 miles after owning the car for 30 days. I’m assuming that’s why previous owner traded it. It’s a lemon.
