“I had by back hatch open and I grabbed the door handle to close it. I pulled it down and as I pulled it down I hear a pop and all the glass shattered down on me with the door still open up in the air. Three weeks later I replaced the window. (not a cheap glass almost $1000 with labor to replace) the mechanic opened and closed the door and the hatch to test for defects. All went well. I went to close the door so that I can leave the mechanic shop and I heard the pop and the glass shattered again. …”
NHTSA complaint #10471492, filed 2012-08, 144,000 miles“Gas gauge became very erratic. Finally didn't register at all. Check engine light came on while out of town. Took the car to a merlin automotive for repair. Spent hundreds of dollars and the light would not go off. Mass air flow meter, plugs, fuel rail, throttle position sensor, fuel injectors. They even called in a chevy technician who could not figure it out. When I returned home I took it to my local repair shop where they dropped the tank and replaced the sending unit. Hundreds of dollars in expenses. …”
NHTSA complaint #10425343, filed 2011-09, 99,000 miles“The electric seat control panel which is located on the drivers seat on the lower left side becomes dislodged upon a larger person sitting in the drivers seat. My vehicle had this problem and was taken to a GM garage and the panel was reattached more than once if I remember correctly. The side panel still continues to come off. The dislodging of this panel could cause the seat to move while the vehicle is in motion unexpectedly repositioning the driver and change the drivers position relative to the steering wheel as well as the brake and gas causing loss of control.”

NHTSA complaint #10270226, filed 2009-05, 70,000 miles“I have a 2006 chevy Trailblazer Ext. I was driving around and it was pretty windy. I noticed that there seemed to be alot of air coming in thru the rear hatch. When I opened the glass on the rear hatch I noticed that the hinge had come unglued from the window. Since it was windy it also caused some of the other hinges to crack and break where the 3rd brake light is located. I had to forcibly close the rear window and now it is only being held by one hinge on the right side and in the lower middle where it closes and locks. …”
