The front windshield wipers on this car fail in light ice or snow. They've broken every winter I've owned this car (four years). This results in me driving around without front windshield wipers until I can get it fixed, watching the weather forecast and hoping I don't get caught in rain or snow. It happens despite my best efforts not to use the wipers in freezing weather unless absolutely necessary, going so far as to drive in light snow or rain without wipers to avoid breaking them. I've fixed it myself (not easy, especially in winter weather) and paid a mechanic to fix it for me at least three times. Most recently, the mechanic replaced the entire motor and linkage assembly which was extra expensive, but the right wiper broke again this thanksgiving. (until this last time, both wipers have always broken together. ).
The vehicle's blind spot detector turns off at low speeds potentially putting the driver at risk if the driver depends on the blind spot detector. The collision avoidance system is unreliable. When the car in front switches lanes and there is a stopped car in front the vehicle starts to slow down but releases the breaks about 50 ft from the stopped car and starts warning of impending collision. And the breaks are not applied.
