CTV reports that some General Motors vehicles may have a serious defect which could lead to total engine failure.

The issue is the intake manifold gasket in some GM vehicles. According to CTV, the part may degrade in vehicles built between 1995 and 2003. In worst-case scenarios, the gasket is failing, introducing coolant to engine oil, rendering the latter ineffective and resulting in siezed engines. Affected vehicles include the Chevrolet Monte Carlo, Pontiac Grand Prix and Aztek, and several Oldsmobiles. Service bulletins obtained by the news source indicate the automaker has been aware of the problem for years.  However, GM currently does not have a recall on these vehicles, since degradation can have a variety of causes.

An online petition asking GM to issue a voluntary recall has collected some 11,000 signatures.

A full-listing of affected vehicles can be found at the link.

GM has since come out with a new, redesigned intake manifold gasket for its newest vehicles.

(Thanks to everyone for the tips!)
