Discovered during a vehicle inspection that oil was leaking around the upper part of the engine...near the head and intake manifold area. Plus have been smelling burning oil through the ventilation system...occasionally. At the time, vehicle was no longer under manufacture warranty...contact manufacture for assistance, but assistance was denied.

We purchased this car in July 2002 from classic Chevrolet in owasso, ok. We also purchased an extended warranty. In December the car was hit from the rear by a hit and run driver. In January the engine began to knock. I called the warranty place and got permission to take it to a mechanic, he said it was the intake manifold gasket, replaced it when it still knocked he said it would take awhile for all the water to get out of the engine. We took it back, and got a run around for 4 weeks, finally called the warranty place told them he wasn't getting it fixed and requested permission to take it to a different shop. Granted then when they found out it needed a new engine they refused to pay for it, said they would only contribute a sum of money toward fixing it. I called gmac because they financed the warranty, one person told me that GM should honor the warranty and so I have a call in to a dealer in pittsburgh, ks. We no longer have a GM dealer in our town. My point is that someone needs to make this right and put a new engine in my car at no more expense to me. When I talk to GM I will be letting them know that I found your site and checked it out, and lodged a complaint. I am unsure of the exact date of the incident and since it is 4:15am am unable to call and get it.

I have a 1999 Oldsmobile Alero with a 3.4L V6 engine that leaks coolant from the intake manifold gaskets. My dealer is jim muir Oldsmobile, who put me in contact with GM customer service. They claim no knowledge of the problem. According to the internet, there are thousands of vehicles with the problem. My father, who works at GM says that at least seven people he knows in his office have had repairs done. GM needs to acknowledge the issue and start fixing them.

The lower intake gasket & oil pump drive O-ring seal is leaking coolant internal & is mixing with oil, engine will need to be replaced. This car is only 2 1/2 yrs old, the intake gasket and O-ring seal should not leak fluid; this must be a manufacturer's defect. I have taken the car in for service (fitzgerald auto mall- Maryland) consistently..... idlerpulley - I had the serpentine belt replaced in Nov 2001(113.38). In February while driving on the interstate all of car systems began to fail. Once the alternator was drained dry and the car coolant, the battery died, because the serpentine belt came off. After two hours in the rain we were able to get the belt back on and I took the car to the dealership the following day. The dealership discovered the idler pulley bearing was loose and needed to be replaced...this cost $117.47. The dealership would not pay claim any liability, because it had been two months since they had replaced ther serpentine belt and felt anything could of happened since November. I am sure it is not common for an idler pulley bearing to become loose, this may be a manufacturer's defect. Thank you.

On three occasions I have driven my car to my destination and when I go to get back in the car it won't start. It have left me stranded each time and a tow truck was called. The dates this happened was 8/22/99, 9/14/99-9/17/99 & 9/22/99-current. The dealership still has my car to this date. They admit that there is a defect which they thought was the fuel pressure regulator because they've had this problem in other Alero's, but apparantly that wasn't it. I forgot to add that after the car sits for awhile, it starts back up, so the it won't duplicate itself at the dealership. You never know when this will happen, but I have noticed that it has occurred within 24 hours after filling the tank up with fuel and I told them this because I thought it may have something to do with it not starting up or something in the fuel line was defective. I personally think that the car needs to be recalled. I've only had the car for 5 months and its been in the shop twice. The first time it happened it was on a weekend and the dealership was closed. So far my car has been in the shop cumulative 15 days. I think this is a safety issue because it has left me and my son stranded and I don't know if this has happened to anyone else, but I feel that the consumers need to know this. This is my only means of transportation and I do not feel comfortable in that car any longer and am not taking it back. We have yet to work out a resolution to this problem. Please contact the dealership and the manufacturer (General Motors) to investigate this problem. This could result in a much more serious problem if the defects aren't detected. I spoke with brent walls, GM factory representative @ 1-800-823-0055 X8174. I have also filed a complaint with Oldsmobile 1-800-442-6537 file #990072405 and with the attorney general's office and BBB autoline. Please contact me with any suggestions or to discuss this claim. I appreciate any help you can give me.
