The dash on my truck has cracked by the passenger airbag and also by the instrument cluster behind the steering wheel. Online forums prove that gmt900 vehicles (tahoe, suburban, yukon, silverado, sierra) have this issue. The headlights keep blowing and have replaced them 8 times. This is a safety problem due to having to drive at night. Also both right side doors will not unlock and this is a major problem when you have a small child.
