“My 05 trailblazer keeps shutting off while driving down a city street. In a 2-mile stretch it shut off 5 times with complete loss of steering control almost causing a serious accident. The vehicle trembled and then turned off. It has shut off on me while driving on three other occasions on previous years but it only occurred once and then stopped on those occasions.”
NHTSA complaint #10836804, filed 2016-02, 80,000 miles“Our 2005 chevy trailblazer speedometer just quit working. We can be sitting at a complete stop and the speedometer will read 50mph. It will randomly change and later will even drop below the zero mark. We have no idea how fast we are traveling when this occurs. Yesterday, while driving from oh to in, I had to guess how fast I was going on the freeway. The speedometer started our reading 45mph, so I estimated that I had to travel at 110 MPH to go 65mph. …”
