General Motors Complaint - Defective Engine 5.3t
CLEVELAND, OHIO -- 2004 GMC sierra pickup / engine has defective cylinder heads that crack and leak anti freeze into engine. The engine / Alldata bulletin no. 06-06-01-019 . Gradual coolant loss over time with no evidence of leak found. GMC refuse's to assist in any repairs. I find the new 100,000 mile warranty they have is a lie and come on to dump defective products on loyal customers.
