I drove a Lumina that had a problem that sounds like same type of engine shutoff problem that has been in the news lately. It happened most often when driving on the highway. As I decelerated on exit ramps, the engine would shutoff. This became a fairly regular occurrence with this car. Several mechanics were unable to solve the problem. (I believe it was a 1994 or 1995 Lumina that I owned. I could not find a record of it.)

Vehicle intake manifold gasket is leaking. This is due to the manifold being made of plastic which breaks and causes it to leak. GM is aware of this flaw but I did not see recalls so I am reporting this matter in hopes there can be a recall for the faulty part.

The low coolant light came on while driving. Consumer took vehicle to the dealer, and was told that everything was okay. They flushed the coolant and filled it. Drove it again, light came on again, and temperature gauge began to run hot. Took it to dealer again there were no leaks. They drained out the oil from engine and antifreeze also came out.

The temperature gauge started to go up and down. It was found that there was anti-freeze in the oil, a seal was replaced. But that has not solved the problem. Looks like I will have to replace the engine. Mechanic stated that there are problems with that engine, and showed the seal which was bad. He stated that it is a bad design.
