“This car is registered under my sons name, [XXX]. I helped him buy the car as we paid cash for it ( Money was provided by my ex-wife). We bought it on XXX and was sold as-is but then the seller said theres no problem with it. A week after we bought it as my son was driving it on [XXX] it drove it suddenly loss power then it stop. He was in the middle lane in a 45 mph road. He said it started to run again after a few minutes after a several minutes of turning it off. After that the car randomly kept giving error messages regarding the Hybrid system, losing power and telling driver to stop car and turning it off while driving on the freeway. We called the seller (Jalal) about the issue and he recommended for us to take it to his mechanic nearby. We took it to his mechanic and he did some test on it. We dont really know everything he did but a day or two later it started giving the same error message and a few days after it give another warning to stop and turn off the engine as it lost power again. After that we got in touch with the seller (Jalal) again to let him know that we were still having the same problem. In XXX we agreed again to his recommendation to…”

Electrical system

6 reports
“The Hybrid Warning light came on. This was the third time this has happened. The first time Kia said it was the Air Box and I paid $600 to repair. The second time the shop mistakenly cleared the codes before determining the cause. The third time they say it is the Wiring Harness and will cost $4,550 to report if they have the harness. This vehicle has recall for the connecting rod in the engine which I suspect is the real issue due to clicking noise it makes just before the lights come on, but each time I take it in I am told it is something else. Since it is the Wiring Harness this time it could be a fire hazard especiall on a Hybrid with Lithium batteries, I am not going to repair it as it has left me on the road too many times and I am sure it has the connecting rod issue. I hope nobody else has this issue and unfortunately Kia does not seem interested in repairing it, it was in the shop for 6 weeks before they diagnosed it.”
