1999 olds Alero 70,000 miles and will have to spend over 700 replacing the intake manifold gasket. If we do not repair, will lose engine at over 2500 expense. We have talked to shops and read internet issues predominant on this same issue. GM should do a recall on this vehicle due to so many complaints on this issue.

My car's coolant light came on the first time about 2 weeks ago. At that time I replaced the coolant that was missing, only to have the light come on again 2 days later. I again replaced the coolant. I could not find any visible leaks under the car. I was driving to the mechanic when my check engine light came on, and the check coolant light came on. The cars tempature gauge was topped out. I had to pull over to the side of a major freeway and call for help. After 2 hours of waiting for a tow truck. The mechanic tells me that the upper and lower intake manifold gaskets need replaced. Also, the coolant had leaked into my engine and mixed with the oil causing the engine to miss. I had to have the gaskets replaced with a new version. And also have the engine flushed, an oil change and a coolant flush as well as a coolant change. All of this costing well over $700. Apparently, GM has issued a service bulletin related to this issue but has failed to issue a recall on that particular part. My safety should be of some concern to this car manufactuer to say the least!

A leak in the intake manifold that is allowing coolant and oil to leak into the engine. It costs between $600 - $800 to repair and this is a faulty part in a majority of the GM vehicles. There was a service bulletin dated March 2003 that entails the exact details of the problem, yet GM has not offered its customers any remedies to the problem such as paying for the repair. I have maintained this vehicle with all required service work. I want GM to pay for the repair.

I bought my Alero in may of 2003, and it is not March 2004 and I am replacing the motor. Started out with brake problems, then went on to the leather under the windows and on the dash "bubbling" up in the sun. Next, I had coolant/oil leaks at the intake manifold. Low trac light came on all the time, low tire pressure light stays on, the fan for the A/C or heat only worked in the 3-5 positions. (it's full blast or nothing.) coolant light frequently came on, transmission fluid vanishes, coolant leaks, yet no one knows where from. The temperature gauge never goes below halfway, and it ran hot a lot. Had to replace the coolant cap and overflow resevoir. The gas hand sticks, the speedometer sticks, the leather seats are tearing, had to replace the factory radio because it would not pick up any channels, rear defrost works only when it wants to, and service engine light stayed on about half the time. I took this car to 7 mechanics, had it hooked up to diagnostic computers, had everything checked-yet no one could tell me what was going on. Finally, I left the mechanic shop after being told that the car was "good to go" (which I would never put in the same sentence with Alero again.), and it starting skipping. I had it towed, only to find out that I had a cracked block and cracked heads. (new motor needed-final prognosis) my mechanic told me that it would do absolutely no good to put a motor in it because in 2 years-the new motor will do the same! Oldsmobile should be ashamed that they would recall a glove box latch, yet not the motor. After reading the reviews that I have read in the past week, I am seeking legal action in regards to this issue. I did not pay $17,000 for a lemon, which is all I got!! don't buy!! buyer beware!!
