My driver side window failed preventing me from opening window,needing replacement in may 2014.”
NHTSA complaint #10621903, filed 2014-08, 44,000 miles“I have a 2000 Buick Lesabre with 52000 miles on it. When the fuel gauge drops below 1/2 tank it starts moving erratically. It will move up to full and then drop down to 1/4 tank, just moves back and forth so below 1/2 tank I don't know how much fuel I have. It also confuses the fuel system computer in the driver information center so that is not reliable either. I just have to keep track of my mileage and based on fuel economy I determine when I need to buy gas. …”
