Lost power,unable to accelerate. Engine labored forced to drive at slow speed to dealer shop. Car at dealers shop for 7 days. Unable to get a pick up date. Car has 16500 miles was in shop for factory recall prior to this problem
Engine just lost almost all power,car has only 5000 miles, had same problem when we first bought new car after 24 hrs took it back and they gave US this one ,someone is going to get seriously hurt if not killed with engine losing power,car is in Kia shop now ,very dissapointed in this car, have been a Kia owner15 yrs with 5 new cars
Vehicle was slowed to a stop for a traffic signal. The vehicle then lunged forward in unintended acceleration requiring maximum break pressure to stop the vehicle. The engine was accelerating so the vehicle was shifted into park and turned off. Waited 30 seconds and restarted the engine with no further problems
There has been two occasions in which the car turn off. Lucky it has been while the car was park. One of the occasion we had just pull over when suddenly the car turn off. I find that unusual since this is a new car and it should be happening. Has there been any other complaints about this model?
I cranked my car, put it in drive, and started to pull out of my driveway when my car shook and stalled. All of my lights came on. I then tried to restart my car but it continued to crank over without starting. I gave it a minute and tried it again. The car started, I drove away, stopped at the stop sign, and the car stalled again.
