“I have researched this problem and there seems to be too many people whose windows jam than fall down into the door. I have personally paid over $400 two times to have this fixed. Also another incident with this car are the blinker which sometimes work and sometimes don't. Just this week another problem with the air conditioning. The blower is not working therefore no defrost in this cold weather.”

“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.”

“At approximately 40,000 miles after having had the oil changed, my coolant light came on. When I took it to be checked (even though the fluids were all checked as part of the oil change), it was low. This happened each time I had the oil changed in the winter. Finally, in november I was told that it was a leak in the intake gasket.”
