Recalls, owner-reported complaints, investigations and safety data

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.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

Had some noise coming from the front of the car, had my mechanic look at it, he said we needed a control arm. When he took off the cover to replace the control arm, he found the sub frame had rotten and was cracking. As I looked online, I saw that KIA had a recall for this issue. When I contacted KIA, their response was "as my car is not under warranty, they are not required to repair the car" The car in question has 70, 558 miles on it. We are the 2nd owner.

Door lock/unlock mechanism has failed. Unable to unlock and open door from outside or inside. This defect causes the door to stay locked and unable to open. This can trap people inside of the car if they are unable to crawl out a window or exit from another door. There are many reports of this on Kia forums and general Google search. There was no warning that this part was wearing out until it became impossible to open the door.
