Just bought my car this year with 26350 miles on it. When it got to 30000 needed new tires. The car check engine light keeps coming on. I have took it to the shop and they turn it off. Then when I drive it and it comes back on again. It has broke down on the road four times. Twice I called road side help the other two times someone has helped me. It runs hot because it is bubbling if I drive for more then a hour. Bought the car from power of bowser

I have a 2012 Kia Optima hybrid of which I purchased at the local Kia dealer (Ontario, ca) and even purchased an additional "platinum 100K mile protection." On December 31st my car started to move while in park and the ignition on. I hit the breaks and there was no break pressure at all. The car started to flash codes regarding the brakes and I had to engage the emergency break to stop the vehicle. The dealer could not find the issue and returned the car. Another month later the car did the same thing and I video taped it. The gauges started illuminating and delluminating repeatedly and all the lights on the dash started to flash. The "check brake" code came up again! I now have proof of the vehicle doing this and brought my car back to the dealer now they have admitted something is wrong but they're still unable to duplicate the error. They are keeping the car for further diagnosis but have not done anything but tell me they do not know what is wrong with it yet and that my warranty "may not" cover it. They have told me repeatedly that they will not be able to fix it or do anything for me until they know what is wrong, nor have they offered me a rental car. I want my car back but it is unsafe! what if the brakes go out at a high rate of speed?! please help me NHTSA so we can save lives of others that may experience this problem as well.

The contact owns a 2012 Kia Optima. The contact stated that while driving approximately 20 mph, the tire pressure sensor, ABS, and the stability control warning indicators illuminated until the engine was turned off. The failure occurred when driving through a car wash and during rainy weather conditions. The vehicle was taken to an authorized dealer and they were unable to duplicate the problem. The manufacturer was notified of the problem. The approximate failure mileage was 18,000.

While moving forward at approximately 5mph, brakes were applied to stop vehicle and brake warning light illuminated. So far the dealership has replaced the brake boost pump- 3 times, the brake vacuum pump- 1 time, and the parking brake switch- 1 time. None of these fixes has fixed the problem.
