Our Dash board cracked very badly from the top next to the speaker to the passenger side air bag. We purposely use a dash board cover and never place heavy things on it. This is a safety issue as if getting in an accident wouldn’t be bad enough flying shrapnel would be worse. We just had it fixed at a dealership to the tune of $2500. This is not okay as I see this is a constant problem.

THE GMC SIERRA 3500HD WHILE IN REGENERATION MODE FUNNELS EXHAUST DIRECTLY INTO THE CAB THROUGH THE VENTS. WHILE GM RECOGNIZED THIS AS A FLAW AND CAME UP WITH A FIX FOR IT, THEY WILL ONLY REPAIR IT IN A 5 YEAR OR 100,000 MILE WINDOW. HOW IS THIS NOT A SAFETY ISSUE WITHOUT AN EXPIRATION?
