Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

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.
