  • 10,000 miles
Had the car for less than a year. Parked it and went to remove my key and the key froze in the ignition switch. Was told by dealer service department that it was a known problem and that the parts were on back order. Six weeks later I finally got my car back. Since then, removing the key from the ignition switch requires the steering wheel be perfectly straight and jiggling the key as you are removing it. It has gotten worse in the past several months and there is quite a bit of play in the ignition switch. My mechanic advised me that it needs to be replaced and that the key and ignition switch are no longer manufactured. I'm concerned that at some point soon the switch will lock up again while the car is moving and I won't be able to turn the steering wheel.

When I put my key into the ignition, it froze. I couldn't turn the key. I couldn't move the car. The ignition was locked up. I tried just replacing the ignition cylinder, but that did not work. I had to have the entire steering column replaced. It cost $1371.67 to get this car fixed due to no fault of my own. I have researched this issue and it seems that on the week my vehicle was in the shop, 3 other Pontiac were in the same shop, for the exact same issue. Upon doing more research online, I have found that numerous people are experiencing this exact issue. Due to no fault of my own and due to insufficient faulty parts in the ignition, I had to have this repaired. I had to have my car towed because you can not move this car or put it in neutral to get the vehicle to move otherwise. Funny how it failed 2 months after my warranty expired! how is this fair that their part failed and yet they are taking to responsibility for this? this was a very expensive fix! please recall the Pontiac ignitions! so I am out almost $1500. Bad call GM!

While driver side window is being lowered, window contacts door latch mechanism causing door to become ajar and window gets stuck in place off center. After returning window to up position and attempting to lower window again, door now becomes completely unlatched and swings freely after window hits mechanism. Issue was noticed prior to door becoming completely unlatched. Major safety hazard if window is lowered and door becomes unlatched while driving (to other owners).

Feb 16th 2013 case # [xxx] my car was in for this service for a airbag fault light I was told that "found low voltage to various SRS components" and that according to a GM services bulletin inspection of the SRS wiring system behind the dash is needed. According to the dealer there is a GM service bulletin on faulty wiring harness being the cause. The airbag system could be not working. My concern is with said services bulletin I could not find anyone in the network of GTO owners clubs that were givin any notice of this. But I did find on these forums that one particular wiring harness comes in contact with a metal brace when the cars was converted to left hand drive for sale here that has caused fires. Would not this be a serious safety issue for which either GM or NHTSA would be involved in" GM acknowledged the problem to me in my many emails and conversations with customer service reps on the phone but has not notified owners nor wants to fix the issues. The issue of the airbag failure is another safety concern. Given the nature of these failures why would not this be handled as part of a safety recall? here is just one link to the board where this is shown www.ls1gto.com/forums/showthread.php"T=377773&highlight=wire+harness+glove+box&page=9 information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I purchased a 2005 Pontiac GTO in April of this year, it had a factory warranty still with it. It has been in the shop more then I have driven it. The ABS light has been on 4 times so far. The ECU module has been replaced twice so far. This is an on going problem. The car is going back into the shop as soon as a part comes in. The dealership is aware that is an on going problem. I think this car is a lemon, and I am not sure what I can do about it. The factory warranty expires next week. I would like to know if someone can please help me with this situation. They have replaced the hub in the car once and I have taken the car back and told them it is still doing the same thing I brought it in for before. I am getting tired of not being about to enjoy my car without something going wrong with it. The back seats are also coming undone which I was told it should be covered under the factory warranty which it is not.

  • Manual transmission

Purchased vehicle new, with 13 miles, on April 30, 2005. Vehicle's ECM failed after 1025 miles, at end of August, 2005. ECM replaced by dealer. Failure of ECM placed undue stress on motor. I believe that this lead to the vehicle's engine failure reported in NHTSA claim number 010188397. Old ECM was returned to GM by jim armstrong Pontiac. Motor from claim number is available until servicing dealer completes warranty work, and returns motor to GM.

The contact states there are multiple problems with the vehicle. She has taken the vehicle to the dealership. On April 26, 2005 they replaced the computer, harness, throttle body, engine relay switch, clamps and hangers to the exhaust system. Then on August 11, 2005 they replaced some missing strut tower nuts. There was a whistling sound coming from the vehicle when started. The safety and check oil indicator lights came on. Later, on September 27, 2005 the dealership replaced the engine, exhaust hanger and clamps again, pedal and pedal springs and engine manifold gasket. On October 19 the left tail light was loose, and the clutch pedal went down to the floor. The traction control button and the trunk release buttons would not work. Also, the power steering bracket was loose. They replaced the left tail light, clutch pedal, and the missing right muffler insulator. Updated11/29/05.

This junk is now in the shop [dealer ] for the seventh time! this time it was taken in because the lights, and horn went on and off whenever they wanted too! I took the GTO from hell to the dealer on. Tues. 8/30/05, on fri. 9/2/05 I was told they needed to get parts. Mon. 9/5/05 I was informed the complete wiring harness had to be replaced. This is an insane repair to a vehicle that still has only 3500 miles!!! today fri. 9/16/05 the GTO from hell is still not ready! if this is the way that GMC does business then they should go bankrupt, because they have no idea of how to treat a customer who has supported them for their whole life!!!

2005 Pontiac GTO gas pedal sensor fails. This immediately causes the car to go into safety mode/reduced performance mode. Car becomes unsafe due to the gas pedal cutting out and the car can barely go. Pulling out into traffic, car could suddenly lose power leaving you exposed to a possible collision.
