Faults:

I bought 8 brand new cars from 2003-2011 for me and my family. All 6 were Nissan and I did not have any problems with them.

This time I thought I'd buy a luxury car, and I bought a Buick LaCrosse from 2011. Every time I go to do an oil change, they find a new issue or I find it by myself.

I believe this was a defective car that they sold to me. I have never heard of 3 year old cars having water pump problems or oil leak issues. Mine had, and I called GM and they did not do anything.
