The brake failures are well known by all Tahoe owners. The failures for the windshield wiper control assembly, brake light assembly are all related to poor quality electrical components not intended for any reasonable service life. Junk by any quality standards. The service department at nelda stevenson Chevrolet acknolwdged these components have high failure rates, but they get paid to correct them. The coolantconnector is an extememly poor design. Despite threading into the intake, it is made of a poor quality material that breaks off at the entry to the manifold requiring removal of the manifold to remove the broken threads resulting in a $400 bill to replace a $12.95 part. Again pathetic design and choice of materials to save a couple of dollars in manufacturing. As a design engineer, I find these choices by GM designers deplorable and will buy used bmws from now on. A BMW with 200,000 miles has more service life left in it than a brand new GM product.
