2010gmc sierra. Consumer writes in regards to takata airbag safety recall. The consumer stated the dealer advised the dashboard would need to be replaced at the expense of the owner, due to a crack.

Cracked dash between passenger air bag and defroster, created a rattle service manger at gay gmc said they all crack $800 but they would replace for $400 I have extended coverage $100 deductible gmc has a big problem of product defect not from wear. I want it replaced at no cost
The door cable
The truck was parked in my driveway when I got in and started the ignition. As soon as I did, the plastic dashboard cracked at the passenger side air bag. One week later, same situation, as I started the ignition, the dash cracked above the driver's side instrument panel. The cracks have continued to grow since initially appearing. I have a safety concern that the passenger air bag will not deploy as intended since the integrity of the dashboard has failed, and further concern that if the air bags do deploy, that the dash has become so brittle that there will be sharp chards of plastic in the passenger compartment as the dash is shattered into pieces from the impact of a crash.
Drivers side inside door handle - chrome is peeling edges are sharp cut hand opening door
Engine lifter issue/low oil pressure problem relates to having the lifters replaced. The 5.3 vortec engine has afm (active fuel management). Dealer wants $5800 to fix the lifter issue, while estimates to replace the engine with necessary parts runs between $6900 and $7200. Is this a manufacturer problem? Truck has 52,000 miles and has been serviced at regular intervals. Truck was parked when the issue became evident during the startup. Truck is now at the dealer (towed) awaiting repair.
'10711995'
A crack has formed on the passenger side of the dash board near the air bag. This should not occur in a vehicle of this age. The vehicle has been to the dealer on numerous occasions without any mention or action to repair. I will be contacting them on monday about covering the repair. I believe that this is a manufacturing design issue and the dash should be replaced under warranty. In the month of june 2015, I had to have my master cylinder and brake booster replaced. The first occurrence was in january 2015 of this year and I filled the master cylinder with fluid because of the brake warning system came on and the brake fluid in the master cylinder was at the minimum level. The dealership advised tat it could be the result of low brakes and to keep an eye on it and if it loose brake fluid to bring it in.when it occur again in june 2015, I took it into the dealer. It was determine that the brake master cylinder was leaking into the brake booster causing the warning likes on the dash to illuminate. At just over 40,000 miles, this should be cover by gm as a warranty item. I believe I am due a refund.
