Takata recall went back to local chevy gmc dealer again for the second time in almost 3 years since I received my recall letter from gm. They looked up recall and again told me that it has been recalled but they haven't agreed on whose going to fix the problem. I am tired of waiting and driving a truck that in my opinion is not safe to drive with this safety related issue. I want this fixed because 3 years is long enough to figure out whose paying and get the job done. If it dosen't get resolved soon I will have to take legal action against gm. I drive this vehicle daily so it needs to be fixed.

Dash board in cracking in two places over the speedometer and two places above the airbag. Cracks are continuing to appear on my dashboard which raises a concern of whether it would shatter if the airbag was to inflate during a accident.
Major issue involving cracking of dash around passenger airbag opening and instrument cluster area. I have noticed several vehicles covering all years and usage with similar cracks some major. Concerned that if an accident with front air bag deployment injury could occur due to fractured plastic.
Dash is cracked in three places, the same as all the others. Door handles peeling and cut my child's had
Tl* the contact owns a 2008 gmc sierra denali. The contact stated all the door latch handles repeatedly broke. The contact's son attempted to open the door and the handle completely failed. The failure occurred more than seven times. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 99,000. Updated 7/16/15
I was driving on the highway when all the lights on the instrument cluster came on and went crazy and so did the radio. The trucks brakes locked up and came to a complete stop. The truck turned off and when I tried to turn it back on it was dead. Open up the hood and disconnected the battery and reconnected and the truck turned on this has not been the only time it has happen.
My truck started to activate the brakes in the middle of the 3 lane 680 freeway, doors started to lock and unlock, navigation went dark, multiple different displays on dashboard, number of lights from the air conditioner unit, came on. Acceleration or brakes would not respond, we were unable to drive off the freeway. It was a scary moment, we were lucky that no big rig was following us, or it would had runs us over, and probably killed us.
Gmc has the door handles made in mexico out of plastic. When you go to open the door the handle breaks off in your hand. Gmc knows this a major design flaw but refuses to stand behind the problem. Just google "gm door handles break" and hundreds of postings come up! My child went to get into the truck the other day and the handle broke off in his hand causing him to fall backwards.
