Engine

4 reports1 crash
“Since April I have been having the same issue. Sometimes when I am stopped and the autostop is supposed to shut down the engine, the engine just sputters and if I hit the gas nothing happens. I have to put the car in park and shut it down then restart it. I try to shut the auto stop off when I get in the car but sometimes I forget. It has happened at over 20 times that I have documented over the last couple of thousand miles, many times in dangerous locations, in the middle of interactions or waiting for a light. The engine light has also gone on and off over the last couple of months. The car is now at the dealership and they say the high pressure fuel pump is leaking. I see there has been a recall in specific Kia Stingers, should my car be involved in this recall? The issue began around 45000 miles and continues at 52000.”

Service brakes

4 reports1 crash
“At certain times when I am braking the brake "skips" it's like i am unable to brake so I end up braking late. It's become a safety hazard since there are times when I have almost hit another car. Also, the other is the silver trim on the exterior looks completely faded probably from the sun but I've seen multiple stingers with this issue and should be replaced and yes the car is dirty but that is not dirt.”

Fuel/propulsion system

3 reports
“My car started skipping or stalling when I'd press the accelerator. Then the check engine light came on. I took it to an Independent mechanic and it showed high pressure fuel pump or system. The spark plugs were changed, but the problem remained. I checked and noticed that there was a recall for that particular problem. I called the dealership and they said my VIN wasn't attached to it. But I do think it should be.”

Electrical system

2 reports1 related recall
“After failed first fix at 300 miles, wife was driving an ran out of gas on highway around 800 miles on O/D. Told this time the entire instrument/gauge cluster is bad. Dangerous situation to run out of fuel on a highway. Kia roadside assistance driver would not come and get her as she was on an Express Lane. Had to fill up car with fuel myself (after scrambling down highway embankment) while standing in traffic lane (fuel fill cap is on driver's side).”

Suspension

1 report
“Bought this vehicle from Carvana.com and have been trying to get it repaired since then. There is something wrong with the steering/braking/suspension system. According to License Mechanic Derek Hartfield at Monroe (248) 980-3262 after a road test - told me the vehicle is not safe to drive. He attempted to repair vehicle and Carvana denied the repair. Carvana instructed me to take car to Dealership, dealer has a wait list, I have a family and need to work. It feels like no one wants to help, and just keeps expecting me to drive from repair shop to repair shop. I just want to drive or they can take the car back if it is a lemon. At present the car has alot of issues and I dont know where else to turn. Issue: Vibration driving, vibration stopping, sounds awful when slowing down from highway driving, shakes with or without brakes, the rear wheels both lean inward when looking at the vehicle from the rear. Note: There was a sticker on the undercarriage of what looks like a repair on this vehicle on the rear right , which is odd because there is no history of accident. But accordingly, some repair was made on or about [XXX] to the Right Rear portion of the vehicle.…”
