As appears to be common with the engine in this vehicle, the intake gasket failed causing dexcool to leak into the engine and thus contaminating not only engine oil, but causing failure of critical internal components due to the fact that dexcool deteriorates/weakens certain metals, etc. In our case, the vehicle's engine completely failed while driving 60 mph on a 6 lane expressway with no prior indication of problems. GM is aware of the problem but refuses to take any responsibility for its inferior design! a recall should be begun immediately. Without quick, calm reaction my preganant wife and two children could have been rear-ended and severly injured or killed. How would GM deal with the publicity of that lawsuit!

Engine: Intake manifold gasket leaking. I followed thru with a complaint to the BBB and to Pontiac's 800 number. I was told I needed to have the van diagnosed at a GM dealer before anything could be done by Pontiac. My dealer quality Pontiac in cocoa, Florida looked at the van and agreed the intake manifold gasket was leaking (November 2002). Quality informed me it would be about $500 to repair. A phone call to Pontiac's 800 # put pressure on the dealer and they performed the work for $100 plus extra for a coolant flush. The total was around $180. Supposedly the work came with a 12 month 12000 mile warranty. I think the van had 58000 miles on it when this work was performed. Looking back I have a feeling it started leaking earlier. Today we have 70500 miles on the van and the check engine light is coming on. The codes indicate that engine cylinder 5 is misfiring. We had new spark plugs put in and will now try new spark plug wires. If that doesn't fix it then we may need to put in new fuel injectors. My complaints to date with this vehicles are: 1. original tires wore out at 24000 miles $500 2. battery died in the first two years. $0 3. drivers side seat belt retractor failed $ 156 - airbag light came on. 4. intake manifold gasket failed $180 5. sliding power door module failed 4 times. $0 6. front brakes drums warped at ~35000 miles $250. Front rotors cut and pads replaced. 7. windshield buzzed from the day we bought it (2 years) and took us threatening the lemon law to get it fixed.

While driving automatic sliding door opened up, consumer took vehicle in to have it inspected and was advised there was a programming function that needed to be reporgrammed, the door worked for a few days and then it started acting up again so consumer took vehicle back to dealership and was told that vehicle needed a new motor activator, the door works fine but sometimes the buzzer goes off for no reason, dealership stated that is ok as long as door is working.

Oil pan has heavy oil residue film which GM claims to be normal due to aluminum casting oil pan design that allows oil to seap through the oil pan. A heavy oil residue on the outside of the oil pan does not seem normal and appears to be a leak. Burning oil can be smelled inside the vehicle while stopped. A file # has been opened by GM customer service to record my complaints. Right hand door powered mirror is loose and loses setting when door shut.
