| Wiper problems |
Engine does not reach normal operating temperature, possibly failed thermostat. Front window does not defrost properly and ices up while driving for 10 minutes after warming up for 15 minutes.
Windshield wiper motor started to operate slowly and at times stops with wiper blades in middle of windshield.
On a dark or dimly lit road the low beam headlights create a sharp boundary looking through the windshield with headlight illumination on the lower area and darkness on two thirds down from the top of the viewing area. It is as if the windshield has a line horizontally across it two thirds down in the field of view. The line bounces when the car bounces and dark upper portion can not be properly viewed through to see the road ahead. It is a safety issue due to poor visibility. The dealer has said a few times there is no issue and no reported issue. All they could do was adjust the headlights an inch. It didn't help. I don't drive it at night unless I have no choice and only very short distance. It got much worse recently. I won't sell this car to anyone, its not safe.
