“While driving down the road, my car shut off and I almost drove off the road because all of the lights shut off and I lost control of my power steering and brakes.”
NHTSA complaint #10610579, filed 2014-07, 203,000 miles“My 11-month old 2003 Chevrolet Trailblazer has had multiple quality problems, twice affecting my safety. Most of the problems have been electrical in nature. The 4wd has become inoperable numerous times, once while driving in snow. In another incident during a severe thunderstorm at night the air conditioner (A/C) failed and I was unable to defrost my windshield in order to see. After one dealer failed to diagnose the 4wd problem, another dealer replaced my ignition switch because the technician said I had no power at all going to the rear grid. …”
NHTSA complaint #10047515, filed 2003-11, 2,392 miles“Our windshield wipers were inoperable. The wiper switch was turned on with absolutely no response from the wipers. The dealership has replaced it. However, other electrical problems keep occurring. For example, our air conditioning switch malfunctioned, the onstar did not send tracking information properly, the alternator needed to be replaced, and the fan for the heater would not work at any speed except low. We have only had this vehicle since august. I am thinking that this in an electrical problem instead of each individual piece being faulty. …”
NHTSA complaint #10047425, filed 2003-11, 3,000 miles“First the RPM gauge stops working properly, then the temp and oil pressure gauge do the same. After all that you get a check gauges light and a annoying dinging noise that wont go away.”
NHTSA complaint #10678767, filed 2015-01, 157,000 miles“If the vehicle is turned on, when you turn on the A/C, the A/C pump will not turn on. You either have to turn the A/C knob on/off a few times to get it to go, or open the front hood, and tap on the A/C pump with your hand to get it to start. This happens at any point in driving or while in park. The A/C will not blow cold air unless you do as I have stated above.”
