Suspension

3 reports
“Finally got car back from previous repairs and it was making a loud groaning noise all the time. Took it back to dealership and they said they had to repair the rack and pinion system and the gears were shredded. Employee says they now have another niro with the same problem as my original symptoms when transmission was replaced twice. Car has consistently had problems with the RPMs being incredibly high at low speeds but the dealership can’t seem to replicate the problem. Car randomly switched over to manual mode after a long drive. Video of problems given to employee and just said he’s going to give them to his field technician. Car has now been at the dealer for over 4 months and was finally returned because they can’t reproduce the problem.”

Electrical system

“Transmission was replaced but then completely shut down as I was making a right turn. Multiple indicators on dash went off and safety errors kept scrolling across dash. Vehicle then wouldn’t shift at all. TCM was replaced but vehicle has high RPMs at low speeds. Has been at the dealership now for over 90 days.”

Vehicle speed control

2 reports
“I was slowly driving in the parking lot of the Meadowmeer Golf course on [XXX] today, Monday XXX at about 11:30AM. As I began the turn to pull into a parking space, at about 5 miles an hour, the car rapidly and unexpectedly accelerated. I immediately slammed on the brakes, leaving skid marks on the payment. Before the car stopped it drove into a curb around a flower garden. The i-pedal was not engaged. Myself and the passengers were frightened but not injured. No one has inspected the car as yet. There were no messages. I am trying to reach the dealer Kia of Bremerton, WA but they have not yet been responsive. The car has been driven about 9500 miles in total. I bought it as a certified used car from Kia on XXX.”
