The only thing that has gone wrong with this car is the rear window regulator on the drivers side. Which the dealership is replacing for no charge.
The body on this car is awesome. It is sleek, sexy and just beckons for your utmost attention... Pontiac has definitely got the wide track to a science. The interior rivals that of a Cadillac, The leather seats, the drivers information center and steering wheel radio controls put everything within the drivers reach. Now for the down falls of the car. The constant high pitch brake squeal tends to get rather annoying. The other down fall is the battery under the back seat.
Batteries last longer under the back seat since they stay cooler than if under the hood.
I feel its safer having the battery up front or in the trunk. I once had a starter stick in my Corvette and the battery compartment (behind the driver seat) filled up the entire cabin with smoke. Also there is acid fume risk and having acid potentially released inside the car in the event of an accident. My 1990 Bonneville LE had a battery up front and lasted a long time. You might save several months of life in the car that's about it.
My 2000 has started either missing at around 60mph, or there's something going on with the transmission. It's going in next week. What can I expect?
