While test driving the vehicle before purchase I felt a very noticeable vibration and road noise. I asked the dealership to see if they could correct this. They rotated and balanced the tires. The tires would also loose 5-10 PSI in the course of two days. I was constantly adding air to all four. For one month the vibration did not exist and it was an exceptionally smooth ride. Then seemingly one day the vibration was back. I took my vehicle to an independant shop and they balanced the tires again. Ride was smooth for about a month and vibration came back. I took the car in and had all four tires replaced. The road vibration and the loosing air issue has never been resolved. Tire balancing helps with the vibration but it always returns shortly after.

I bought this Pontiac G6 in January 2007. Within six months I had it in the GM service dept. getting the rotors replaced. Another six months went by and yet again, I am back at GM service getting the same thing, rotors, replaced. At this point, I explained to them that this is not normal and it needs to be checked into to find out why this is happening. They would never listen to me, and only fixed the obvoious. When the warranty ran out, I was stuck replacing the rotars every 6 to 8 months, I had the hub assembly replaced, both front tie rods, my air compressor locked up.....replaced that, and replaced brake pads a couple of times plus replaced tires twice. I keep up the maintenance on this vehicle and have the tires rotated every other oil change. There is no reason for all of these problems to be happening, and me having to pay out of pocket to have them replaced.
