I have the 2006 GT Coupe. It has a little over 90,000 miles on it & has been by far the WORST Pontiac I have ever bought since the day I took it off the lot! My laundry list of items are:
5 leaks inside the car: 1 leak at each front seatbelt causing such a stench due to the fact that the seatbelt cannot possibly dry out. I imagine this will create a mold issue since it already smells like mildew. 1 leak at each back panel along the doorframe coming down by the rear window & 1 leak in the dome light. - I found out through this forum that the sunroof drainage tubing had come off & was causing the leaks. Cost me about $125 to repair it.
1 Front Headlight leak - condensation
2 broken mirror covers on the visor. Driver side has broken 4 times, passenger side has broken 3 times. Both broke within a month of owning this car.
1 broken passenger seat handle: this has broken completely off 4 times now. All were covered within the original warranty of the car & now Pontiac refuses to cover it & wants to charge me about $75 just for the part. Why?? It's only going to break off again! Needless to say I feel its a safety hazard to have anyone in the rear passenger seat since they can't quickly exit in an emergency. - I just got this fixed for about $50 including the part but I'm sure it will break again.
Panel attached to the dash at the passenger feet side is coming off.
Steering recall for the G4 & G5 should have escalated to the G6 as well. I had the same exact issue as the recall & GM/Pontiac refused to cover it. Instead they offered me $2000 towards a new Pontiac. In their dreams!! Last year I had to spend $1000 to replace the power steering motor & module because the steering was extremely loose. A slight turn & you'd be off in another direction! Last week my power steering went completely out & I couldn't turn the wheel at all. If my 16 year old had been driving she would have gotten into an accident. I turned the car off & back on all was fine. The steering is even tight now like it should be but it's down at the dealer anyway because I don't trust it.
Starting problem since week 1 of owning the car: I'd turn the key, it would sound like it's starting & then die right away. Dealer of course could not replicate the problem & doesn't have any records of me bringing the car in numerous times for this issue & now the problem has escalated to several times a day instead of maybe once a week. They think it's a dirty or defective throttle body. I can either replace it for $500 or do my 100,000 mile maintenance for $750 which covers cleaning it only. If it needs to be replaced it will cost me an extra $500 to do so.
The driver door handle failed & had to be replaced within a year after I bought the car.
I've even replaced the battery on this car twice..first time was within the first year that I owned it.
It kills me to think of all the money I wasted on this car & now have to put all this money into fixing what I think should be a GM issue!! I'm in the process of pulling all of my service records on it & writing letters to both Pontiac & GM. Not sure it will do me any good but I intend to scream about this car all the way up the chain to the president at GM!
