Power train
19 reports
“The dealership is falsely reporting to Kia Corporate and the NHTSA that Recall SC276 is 'completed' by only replacing a fuse. They are refusing to replace the actively leaking, fire-hazardous Hydraulic Clutch Actuator unless I pay an out-of-pocket diagnostic fee. They are violating federal recall safety mandates by trying to release a vehicle with an active, un-repaired recall leak.”
Electrical system

“My kia niro 2018 backup camera takes a few seconds to start up when the vehicle is put in reverse. the time it takes differs from a second to sometimes 5 seconds. I know of accident caused in a McDonalds drive through where someone was backing up but the cam didn't turn on right away and they got in a small accident.”

“On April 21, 2026, Go Kia Renton performed an oil change on my 2018 Kia Niro Touring (VIN). The car was in perfect condition just two weeks earlier — North Seattle Transmission did a full service on April 6, 2026 at 283,649 miles with no issues noted. Later that night while driving, the red oil light flashed. I pulled over immediately and called AAA. AAA towed the vehicle from Belltown [XXX] ) at 12:11 AM on April 23 to my house then at 9:14 AM towed it straight to Go Kia Renton. The AAA driver found oil leaking all over his tow truck. The car now has a dead battery and is showing Hybrid Control System / Low Voltage DC/DC Converter and Engine Control System codes. This appears to be a sudden engine seizure caused by oil loss shortly after dealer service.”
