Recreational Vehicle Lpg Tank Valve/gauge problems of the 2008 Chevrolet Tahoe

My dash has cracked above the gauge cluster and above the passenger airbag.

2008 Chevrolet Tahoe. Noticed cracks on the dashboard towards the front passenger side near the air bag components and cracks on the driver side near the gauges. The approximate failure mileage was 113,500.

I own a 2008 Chevrolet Tahoe 4x4, I purchased it with 80000 miles on it. When I start the car or I am driving all my gauges on my instrument cluster pass beyond the maximum level, even my speedometer sometimes I will be going 40mph but it is marking 80mph. My temperature gauge, my battery gauge, my fuel indicator gauge, even my oil pressure gauge stopped working. The worst part is that my prndl and info center also dissappear while I am driving and they re-ulimunate sometimes after few minutes sometimes for days. The dealer said they have no fix for this, other mechanics said that gm has this issue on most of their trucks and suvs. I think this issue is very unsafe for drivers especially when all your gauges stop working or work improperly or dissappear from your screen, I beleive this can be dangerousto drivers as well as other people on the road and gm should find a fix for it. Thank you.

While driving 65mph on the interstate in very good driving conditions, I heard a loud pop and realized that my dash had cracked. The crack originally stretched 6-7 inches from the edge of the dash close to the windshield above the gauge cluster toward the driver. The crack continues to lengthen and my concern is this presents a safety hazard that increases as the crack gets longer. Another crack is forming where the airbag is located which will present a considerable hazard in the event of an airbag deployment as any shards of plastic could become potential projectiles that may cause serious harm to myself or a passenger. I have been a lifelong loyal gm customer and I disappointed with the performance of this component. I brought this concern to the attention of the local dealership and they will not address the obvious failure of the dashboard.

Dash has 2 large cracks above the instrument panel and another one at the passenger airbag. During operation, stabilitrak light comes on, all gauges go to zero, doors begin locking/unlocking, vehicle loses power, radio goes out and clock resets, lights flash, and battery dies as soon as ignition is turned off. Numerous calls to gm and visits to dealership. No fix as of yet. This has been going on for years. Now odometer has reset to zero.

I have had a cracked dash over the air bag for several years and then another crack happened over by the gauge cluster so it's broken all the way through and the dealership will do nothing but charge me way to much to replace it. How do we get this fixed?.
