As part of that link I found this... It is vague in the other repairs caused by this gasket failing.
This really sounds like it is regarding the lower intake gaskets on the 3400 and 3100 engines. This is I am sure also tied to Dexcool, which Dexcool was not the issue but the gasket matial not being compatible with Dexcool.
Not saying what happened is right, but good luck on very old vehicles.
A recall is more for a safety issue, not a bad part going back to a 1999, or 2002 vehcile.
To: General Motors Corporation & The Better Business Bureau
We, the undersigned petitioners, General Motors’ customers and/or technicians who service GM products, do hereby give notice that we are more than dissatisfied with the quality of the intake manifold gasket installed in GM vehicles. As of April 10, 2002, there is a nationwide backorder of the intake manifold gasket. At this time, is it not even known when the part will become available. Being aware of this proves there is a serious problem to be addressed. Because of apparent poor engineering, GM can not manufacture replacements fast enough for all the vehicles in which they are needed.
Intake manifold leaks can lead to any number of very serious, and expensive, problems. While the part itself isn’t costly, the labor to repair it is very intensive, and has been quoted around $800 USD (give or take a couple hundred depending on the vehicle). This is in addition to any other costly problem(s) the intake manifold gasket leak may have produced.
We are demanding accountability from General Motors. A nationwide backorder should be reason enough for GM to assemble a recall. We can only hope that “the world's largest vehicle manufacturer” who “has been the world's automotive sales leader since 1931” will stand up and claim responsibility for a problem that is so prevalent among their vehicles. Recalls should be mandated in all cases of incompetence, not solely when it affects public safety.
While some of us have been “fortunate” enough to have this problem occur within our warranty, there are many others of us that have had to pay for these expensive repairs just after the warranty expires. Because GM has refused to admit liability on this issue, we feel that this will be a repetitive problem. Once this gasket has been replaced, and customers’ pockets drained, GM Service Centers everywhere can expect to see consumers returning, for this same problem that hasn't been rectified due to a designing flaw on GM's part. This error should have been corrected, not the first time in for service, but before entering mass production in millions of vehicles.
Can one presume this is one way of keeping General Motors’ patrons coming back time after time? Sincerely,
