“This has now happened twice. In 2016, my car shut off while driving and I was able to start back up. The pass lock flashed and then it shut off. I changed the key thinking that would fix the problem. In 2017 the something happened again. I went to the dealership and they said they don't think it's the ignition switch and that was it.”

NHTSA complaint #10715742, filed 2015-05, 120,000 miles“First occurrence I smelt burning plastic and saw some smoke coming from the master window switches on the drivers door. The switches failed, windows stopped working and when getting them replaced the inside sound proofing was black and burnt. The second time I didn't smell smoke but the windows stopped working and the inside of the door is burnt. The switches failed and the drivers door window stopped going down. The switch needs to be replaced.”

One evening my husband was in front of me and the washers would not stop and finally ran dry. My husband pulled the fuse under the hood to deactivate the washers and the one under the back seat to deactivate the wipers. I drive my Trailblazer like this. …”
NHTSA complaint #10633040, filed 2014-09, 140,000 miles“My husband was driving about 40 MPH on a country paved road when his side airbags went off. His radio and lights started flashing. He was able to get home the mile or so, parked the car and shut it off. When he went to start it the next day nothing worked. He was startled by this happening and was lucky he didn't cause an accident or get hurt. He could have caused an accident very easily due to the visibility. Not sure what caused this to happen. …”
