"takata recall" was driving down the highway doing bout 70mph and I hear a nosie on the roof and then I saw my whole 3rd break light asmbley break off and fly into the air and almost hit the car in back of me this can cause a major accident if it fly's off and hit a car in back of you and I was doing research online and saw its a common problem with these SUV its a poor design and needs to be recalled before somebody dies.

The problem that I have with my truck is an electric problem involving the light relays, which I ad to replace several times due to them being damaged, leaving me without lights. My main concern is that I drive at night often and I am in danger when I have the lights on and off. I did research on several forums where same-vehicle-owners have experienced the same issues.

8 Exterior Lighting problem

Failure Date: 08/29/2008

I am a senior citizen I brought this car new. After one year I had to replace linc plate. Over the years everything has gone wrong with this car. Speedometer has not worked since Aug. '08, gas gauge stopped oct. '11. Instrument cluster since 2010 and gm knows this is a defected part. Yet gm paid for this same defected part at their cost for the tahoe, but has not paid for the Trailblazer. Why? windows and doors do not unlock on command. Window wiper(rear) stopped working-I replaced that part. A/c comes on my itself. Thermostat failure. I think gm should stand behind their product. The only reason they would not is that they already know that they are producing substandard products that are not fit to be driven on the road.
