Lesson Learned : Check engine for coolant leak if you own a 1996-2003 GM vehicle with either a 3.1L or 3.4L V6 engine. Your engine may self-destruct without warning!!!
I have a 1997 Venture with a dead 3.4L V6 engine (37,000 mi). Two weeks ago, the engine abruptly died while vehicle is running. Prior to that, there was no sign that anything was wrong. No engine overheat, check engine light, fluid on the ground etc., the only incidence was a lit "low coolant light" and a re-fill with Dex-Cool. After a tow to the dealer, I was informed that I would need a new engine installed for $5200. The problem was that coolant had leaked into the engine via the intake manifold gasket, which seized up the bearings causing the camshaft to break. I immediately contacted GM Customer Assistance, thinking that the mileage is too low to have required engine replacement and coolant has started leaking long before the warranty end. After pleading for help and leaving many messages on un-returned phone calls, I was told a week later that GM CANNOT render any help (even though the 4 yr/50000 mi warranty expired out of time but not of mileage). The only and FINAL "help" came from the dealer dropping the price to $4500.
I shopped around, talking to local repair shops and did some research. One repair shop told me that they did 2-3 vehicles a week with this coolant problem. Most had intake manifold replaced for hundreds of dollars, but quite a few had engine blow-ups just like me. If you look up this web site
While shopping around, I find that I can buy a brand new GM Goodwrench engine from GMPP for $2000 and have it installed for about $1100. So I think the GM dealer still makes a handsome profit with its last offer. Their priority was apparent when they refused to release the vehicle unless I pay them $45 for the work they did: say maybe 10 minutes of labor to check compression in two cylinders? They said they did me a favor by not charging $90.
Now the Venture is sitting in a repair shop waiting for a used engine to be put in (for $2900). It will come with a 1 yr. warranty. I am keeping my fingers crossed for the used engine to work. I will get the dead engine back for autopsy and future claim against GM. Another GM car I had, a Grand Am with the 3.1L engine (36,000 mi) had the intake manifold gasket replaced by dealer a few months ago under warranty (surprise !!, surprise !!! the "low coolant light" turned on this one too). Now that I've learned how this engine can self-destruct without notice, I have quickly traded-in the Grand Am for another vehicle. Just imagine being caught with sudden engine failure on a busy freeway scares the hell out of me. I have owned exclusively GM vehicles in my household for at least the past 25 years. So with the one of my three GM cars now gone for good (you didn't expect me to replace my Grand Am with another GM car did you? the other cars will soon follow), a perfect example in the making of how GM is losing market share.
Hopefully, GM will one day WAKE UP and start taking care of its customers. You have to question the wisdom of a company when it is willing to give $4000 incentive to sell a vehicle but unwilling to spend a single penny to retain a faithful customer. Furthermore, given the extent of the problem, any responsible company would have recalled these engines already
TRUE story but SAD to see a great company seeking its own destruction.
