I have had to replace 4 engines 2.4L on my 2001 Oldsmobile Alero. My last engine lasted 32 days after I spent 1200$ and now I need to have work done to it again.

I purchased a used 2001 Oldsmobile Alero in December 2003 with 41,805 miles. After having the car for only two months I noticed a puddle of coolant under the car, I took it back to the dealer I purchased it from where I was told that it was leaking from the intake manifold and that my warranty would not cover it due to it being a gasket. I also was informed that my water pump was leaking. I learned through research that this is a very common problem with GM vehicles so I contacted GM and was told that I had to take it to a GM dealer to have it diagnosed (I purchased it from a Honda dealer and GM wouldn't take their diagnosis) to see if GM would assist in the repair. I took the car to a GM dealer and they confirmed the problem was the leaking intake manifold gasket and was told that GM would not be of any assistance with the cost of the repair. I was also informed that I would owe the GM dealer $30 for the diagnostic test (which GM also declined to cover) to find the problem; I was never told up front that they would charge me for the test and basically the test was not required since I (and GM) already knew what the problem was and was told by them to take it to a GM dealer for consideration for assistance. I have read hundreds (if not thousands) of complaints against GM for the same problem and also internal service bulletins from GM indicating that they were well aware of the problem with the intake manifold gasket. This is a very costly repair (between $800 and $900 dollars) for only owning the car for two months.

Failure of intake manifold resulted in coolant leaking into the engine after only 40,000 miles, I am finding this is a common problem often resulting in engine failure.
