ENGINE DESIGN FLAW: GMC 3.1L & 3.4L V6
ENGINE/ INTAKE MANIFOLD GASKET*****
GASKET ALLOWS ANTIFREEZE TO GO INTO
OIL CAUSING AT MINIMIUM REPLACEMENT OF
GASKET. BUT GOES UNDETECTED CAUSING
ANTIFREEZE TO ACT LIKE GLUE THROUGH
OUT YOUR ENGINE. CAUSES ENGINE
FAILURE. THOUSANDS OF DOLLARS DAMAGE!!
GMC AWARE OF THIS FLAW. REFUSES TO
HELP CUSTOMER WITH COSTS OR WARN OF
PROBLEM. check for recalls and
complaints. DOT auto safety hotline
with U.S. dept. transportation.
nhtsa.dot.gov/hotline/ GMC could
warn customers and help them avoid
costly bills.

Best Features

Worst Features

FIX INTAKE MANIFOLD GASKET!! PASSENGER CUP HOLDER CHEAP. BREAKS A LOT. ADVERTISEMENT SHOWED IT HAULING A HORSE TRAILER. CERTAINLY NOT WITH A HORSE IN IT.
