What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Car accelerated on its own, rpm's revving while driving down a major highway. Could not get car to slow down so had to steer car into a concrete barrier. Problem existed before the accident doing the same thing(rpm's revving) in park or reverse or accelerating on its own without pushing the gas pedal.
The seatbelt didn't catch, nor did the airbag deploy, and my head hit the steering wheel, chin first.
We ran into a telephone poll at about 25 miles an hour and the air bags did not deploy and seat belts did not look, passenger hit the windshield with head and driver hit his chest into the steering wheel and hurt chest.
The vehicle has excessive oil consumption despite being consistently and properly maintained. I have been meticulous about maintenance because the vehicle has a lifetime powertrain warranty, and I have documentation and receipts for required maintenance, including regular oil changes and other scheduled services.
The airbag warning light and the ABS warning light turned on simultaneously while driving. This is a severe safety hazard as both critical, life-saving safety features are currently compromised.
The GDI 1.6L engines are manufactured with a flaw that affects piston rings and makes oil consumption go up which in turn can make the engine run dry and damage the engine, which if you're in a bad location could be dangerous. My car has been dealing with the issue and I searched yet found no recalls for the engine.
Our granddaughter bought this car from a private seller. My son is a mechanic and when he inspected the undercarriage he found a small leak in the seam of the gas tank. The local KIA dealer said it is not covered. This, to me, is a safety and emissions issue. Please assist.
The contact received notification of NHTSA Campaign Number: 23V652000 (Service Brakes, Hydraulic) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair.
