Bought a new 2005. 2 months after warranty went out the ignition messed. Have to wiggle the key to get it to turn. Two months later the heat/ac blower control switch went out. At 120,000 miles leaking lower intake manifold gasket, fixed that. 3 months later blown head gasket, found bad fuel injector while fixing that. 6 days after all that was fixed the pcm/ecm went out, still at shop as I type. Wonder what is next. I have always owned gm products, but I believe this is my last one. I have been told by two mechanics that the bearing in motor will now go bad since water got in oil twice from leaking gaskets. 3 mechanics told me this motor is known for blown head gaskets and leaking lowing intake manifold gaskets. Online there is talk of a recall on the pcm/ecm but dealership says no recall.
The contact owns a 2005 Chevrolet Equinox. The contact stated that the heating system was inoperable and that the engine would overheat. The vehicle was taken to a private mechanic who flushed the heater core, performed a pressure test, replaced the cylinders, intake manifold gasket set, oil filter, head gasket, exhaust manifold, distributor o-rings, head volt set, and the antifreeze. The contact did not inform the manufacturer. The current and failure mileages were 55,075. Updated 02/23/lj updated 05/20/11.
Auto was at rest at a stop light just after exiting expressway. Auto seemed to lose power when the engine light came on and the temp gauge was reading hot. I slowly drove about a mile home. At this time I turn off the auto and opened the hood. I let it sit turned off for about an hour, at that time I tried to start the auto and it wouldn't turn over. I let it sit overnight and tried to start next morning, it turned over hard and started. I turned it off, checked the coolant it was very low. I added coolant, let it run about 10min, lots of steam come from tail pipe and no heat from vents. I then checked engine oil, it seemed watered down. A friend who knows cars told me head gasket. My 3year old chevy now needs at least $1500 to $2000 worth of repairs that may not be under warranty.
