I bought (2) Sierra 2500 hd trucks that have serious hub assembly problems with one replacement in 2011, lighting system work when it want to and has drain five batteries from aaa and advance auto in the past seven years, abs/engine light stays on since 2007 and after 10 years is gasket problems with gm products. I have talk to gm executive office that fix the hub assembly and tailgate recalls problem in 2011 but unwilling to deal with it now after talking to gm dan. I think I need out side counsel and engineering firm to test and testify on my behave and 2,300 other owners with the same problem. I want new vehicles and setting up a date with congressional oversight committee, and NHTSA review my case. I have met with congressional panel investigating gm that want to help me resolve this problem. I been a gm person but seriously looking in the foreign market if I have no serious resolution.
Flywheel on four locally owned gm trucks were reported being cracked or broken. Old parts are avail. Since then speedometer doesn't work properly and I am told there's no problem.
