2000 Oldsmobile Alero. Diagnosed with a leaking lower intake manifold gasket at 55,000 miles (~ $800 repair). Contacted Oldsmobile for cost assistance because this is such a common problem. They told me that this was a case of negligence on my part. Considering discussing with a lawyer due to the high volume of similar problems on this engine type.

Intake manifold leaking on 2000 Oldsmobile Alero. Oil system is contaminated, and engine is running poorly, and will be permanently damaged if not repaired soon. There is a tsb out to replace the defective design. I had the vehicle in to a GM service department for diagnosis, and then discussed issue with GM customer service. They will not pay for complete repair because it is out of warranty even though the gasket design is defective.

2000 Alero gls with the 3.4 L V-6 had to have the intake manifold gasket replaced due to failure and coolant leaking. The car had 38,000 miles on it at the time of the failure. This is the third GM vehicle I have seen that had this problem. A 2000 Malibu with the 3.4 L and a 2000 Bonneville with the 3.8L. All of these cars had the new dexcool coolant in them.

My intake manifold gasket began to fail earlier this year. Starting in Sept. 2003 I had to add dexcool every two weeks to my reservoir; beginning in Oct. 2003 I had to add every 7 to 10 days. My car was not quite yet to 50000 miles. GM claims that my problem was not caused by dexcool and that I should have had my coolant system serviced at 30000 milles but I have three pieces of GM documents that say that the coolant system does not have to be serviced until 150000 miles. I was told by one GM service technician that the part I had to replace was a piece of junk. Fortunately there were no crashes or fatalities. I had to add two months to my car note in order to have this problem fixed. The part cost $58 and the repair cost $540. I have read complaint after complaint on the internet that this part has caused many problems and that GM refuses to do anything about it.

I am in the navy and have had my car for around 8 months but just found this site now. My intake manifold gasket went on me at 40,000 plus miles. I have read tsb's and found many others have had this problem. I know Oldsmobile is being phased out but I love my car due to it being my first car and I have been financially stricken due to incidents like this. My warranty had expired and it cost me 600 dollars to repair it. I was told by my family and a navy jag to file a complaint with the better business bureau and the dealership but I decided to take this route. Please get back to me on this. I would appreciate it.

3 months after buying my used 2000 Alero I found that the intake manifold was leaking and needed to be replaced soon. Once I saved up money I took it in and had it replaced. Since then (one and a half months later) my "service engine soon" lamp continually comes on. Place that repaired my intake manifiold gasket has no idea what the problem is--something with my air system. Also, immediately after repair of img my fuel gauge is stuck on (E)mpty.. will occasionally move. I am extremely upset that I wasted my money on a piece of junk. Also, my cruise kicks out when I am in overdrive--has not worked since a week after I bought the car. I have put more money than need be into a car that is only 3 years old and I have not even owned for a month! what is going on with my car??

The brake rotors turned twice and replaced once. This caused the brake pads to have to be replaced. The drivers door automatic window motor had to be replaced twice and now the passenger door window was doing the same thing. The interior light fell out and had to be put back in. The sun visor came loose and had to be tightened again. The cd player had to be replaced. A backlash of electricity caused a fuse to be replaced. The car died on a highway and towed to the dealership. The intact manifold leaked, it was tightened up and one month later the same problem happened again. The drivers side seat belt did not detract automatically.
