So far nothing major has gone wrong with this car.
The car is very comfortable and the cabin is roomy. I'm 6'5" and fit just fine. Although, I would not recomend the (p) leather seats. The seat warmers suck too, I can't even notice a difference when theyre on.
It has pretty decent acceleration (enough for what I need) The 3.8 is very responsive and can even be fuel efficient. On the highway I have gotten as much as 34mpg, city I get about 16-19, mixed driving I average around 26. The car handles well also for being a fairly large vehicle. The heads up display is awesome too, I rarely look down at the speedometer anymore.
My only complaints are the noises it produces..
One thing is that when I accelerate the engine makes a whiny (wispy) like noise. I've read that it could be the alternator, fuel pump, power steering pump, low power steering fluid (which it isn't). If anyone else has this problem and has resolved it please write me a comment. Also, the car rattles almost everywhere you could imagine, which gets pretty annoying. Other than that everything works fine.
Hi. It could be possible the whine is from the tensioning pulley for the serpentine belt. my dads 2003 Grand Prix recently, just a thought.
