Air bags
as mentioned by many customers the dash on the vehicles crack and GM refuses to pay for repairs. Now there is a Airbag recall that needs to be completed and I am told by dealer that the dash will crack more and get worse during the repair and they are not responsible for the damage. This is unacceptable and unsafe as it is costing me and consumers more money for a defective product.

With all the known issues involving the failing CP4 fuel pumps out in the field, why hasn't there been a nationwide recall on this issue? We're being proactive in getting our LML repaired to save our engine. We want our costs reimbursed. This isn't a "small" matter. It's freakin' huge.

The transmission control module (TCM) began acting erratic. At times the transmission will not shift but several times it has gone into park( with no warning) when slowing down causing the wheels to lock and the truck skids to a stop. I was nearly in 2 accidents when this happened. Both time I was hauling a load and caused the traffic behind me have to swerve to not run into me. In looking into the issue I found that in 2011 GM had put out a shop notice that they had a known problem with the TCM and they thought it might be caused by a non-OEM fan belt causing electrical discharge that might impact the TCM. A second shop notice from GM stated that the issue was due to heat and since they…

It is a transmission control module wear a lobster transmission into a Garin. Will not let you speed up or speed down and it is unsafe and GM IS making us pay for the bill.
