Tl*the contact owns a 2003 oldsmobile silhouette. The 6-way power seat control has an opening that allows the webbing of the seat belt to get caught in the control, which raises the front driver side seat. The failure causes the seat to quickly move forward, knocking the driver's foot from the brake pedal to the accelerator pedal. The failure has occurred on several occasions and once it caused the contact to damage his garage door. He then placed masking tape over the power seat control to prevent the failure from recurring. The contact scheduled an appointment with the dealer for an inspection. The contact believes it is a design flaw and that the dealer would be unable to assist. The current and failure mileages were 37,000.

I own a 1999 oldsmobile silhouette with about 55,000 miles. I took the van to a local mechanic because of a knocking noise on cold startup and continual overheating. The mechanic diagnosed the problem as a failed intake manifold gasket. The total bill about $600. The van had regular maintenance. This seems to be a common problem with gm vehicles with the 3.4l engines.

Car went to dealer to diagnose a knocking sound on cold startup. Diagnosed as a failed intake manifold gasket, cost to repair approx $900.00. On disassembly, dealer contacted me and stated that the engine internals were so badly fouled (sludge and deposits) that hydraulic lifters needed replacement, cost approx $450.00. I asked how this could have happened, van has always had engine oil changed at 3000 mile intervals, with new filter and correct oil, and I don't know what to do differently to avoid this happening again. No advice offered, and no suggestions for why the gasket had failed.

I own a 1999 oldsmobile silhouette with 64,000 miles. I took the van to a local dealer because of a knocking noise on cold startup. The dealer diagnosed the problem as a failed intake manifold gasket. The failed gasket ruined the hydraulic lifters and had to be replaced. The total bill was $1500. The van had regular maintenance (oil, filters, anitfreeze checked) every 3000 miles. This seems to be a common problem with gm vehicles and dexcool systems. This could have been a major safety issue had the engine failed while driving.

Engine knock on cold start - we have brought our 2001 oldsmobile silhouette in several times complaining of an engine knock on cold start. Sometimes the knock will go away in a few minutes, other times it lasts much longer. The most recent visit we were told that gm is aware of the problem, but does not believe this engine knock will cause long term damage. We believe otherwise. We purchased the vehicle knew and began reporting the problem when there was only 20,000 miles on the vehicle. We are continuously told that they are aware of the problem, expect the problem, but do not consider it necessary to fix the problem at this time.

No information or advice was offered on why the gasket failed, or why the engine was so badly fouled.
