Selected complaints filed with NHTSA by 2007 Pontiac G6 owners, lightly cleaned up (personal details are redacted by NHTSA).
I purchased my 2007 pontiac g6 4 cylinder with 40k on the odometer on 5/13/2021. I notice right away it started having problem when i drove it home and it has been almost three weeks now and the problem is intermitten. This issue happens on local road city speed (25mph) and on highway doing highway speed (60mph) intermittently. When this issue occurs the steering wheel shake like crazy and it seems like it wants to pull over to the left or the right (feels like the car wants to drive itself). I would have to put some force to keep the steering wheel straight. The error code would pop up on the radio display stating "power steering". There was a recall for this issue for the electronic power steering assist. The problem is that the recall expired 6/31/2006 and my car is made on 7/2006 so the vin number does not fall in the recall list. …
FAILED COMPONENT SYSTEM: Driver & Passenger side Airbag system. SAFETY RISK: I was involved in motor vehicle collision, resulting in extensive front-end damage to my car. Upon impact, the driver and passenger side airbags did NOT deploy, which based on the extent of the damage to my vehicle they should have deployed. CONFIRMED REPORT: Yes, one component of the airbag system has already been reported to NHTSA for this make & model car pertaining defects or a problem of the passenger airbag sensing system/FMVSS 208, which can be referenced under the following Campaign number: 07V146000. While this is one safety component that is known & reported to NHTSA as wqell as GM, the component that I would like to personally repot is pertaining to specifically the driver side airbag as it did NOT deploy upon impact. …
Electrical issue with my pontiac g6 I have had to replace my headlights bulbs multiple times due to the plugs melting I have actively seen the plug smoking and it has happened on both of my drl/low beam headlight bulbs resulting in plugs having to be replaced multiple times as well. My engine light isn't working and yet I have engine codes my service air bag light comes on at random my buckle seat belt light won't go off it stays on when I'm buckled in the driver's seat. My pressure sensor on my fuel tank has low voltage issues. When shutting the car off and opening the driver door all accessories that should of shut off are still active including the radio. The oil light is always turning on but the vehicle isn't low on oil nor does the message appear. When plugging in a car scanner the anti theft system light turns on and at random times will shut the car off. …
When driving the vehicle on the highway the vehicles steering wheel started shaking lightly and then all of a sudden the steering got hard and locked up the power steering and it also put a message on the stereo display saying "power steering". I was able to pull aside of the highway and turn the car off and then back on. That seemed to reset it but the steering wheel kept shaking on its own. I drove it to the nearest car mechanic and explained the problem. I was told it's very common on the Pontiac G6 and that there is a recall for this issue. Now unfortunately when we look up the car by VIN it says it doesn't have a recall but the mechanic and myself have done research and there's a notice about the Pontiac G6 have this exact same issue about the power steering. …
Something is draining battery. I have a brand new battery in it and battery was checked out at battery warehouse. I run car and about an hour the car is dead. I had problems with this car since I bought it from Koons in Westminster Md. I even paid for warranty but every time I took it back it didn't cover it. This happened a lot I got a lemon and they refused to take it back. I put soo much money in this car I could of bought a brand new car. Now I'm stuck with a car that does not want to run again. What can I do about this car? I ran out of money to fix it. Please help. Thxs
Going down a busy highway at night, 1 minute the car is fine, the next minute the lights go off and then the car dies. The service air bag light came on, the oil light came on, the anti theft light came on and the battery light also. I tried to crank it, nothing. I put a jump box on the battery it Crunk. Within the last 6 months I have replaced the starter twice, the alternator twice, the fuse box twice, and the battery twice.
Brake lights stay on when the car is in drive. Cruise control will not work. There are other intermittent electrical issues that are not safety related. With the brake lights always on, other drivers don't know when I'm stopping. The problem is ongoing and has been confirmed by an independent mechanic. there were no warning lights or messages. the problem started several years ago before I owned the car.
Headlight went out . Upon changing it I noticed that wiring harness was burnt and melted. Also was driving and power steering went out driving 65 miles per hour. The cruise control got stuck . Right side making horrible noise at times. This has put me and my five year old as well as anyone driving near me at risk of dying.
Electrical system has mysteriously drained 2 batteries, the exterior lights vary on which will work despite the bulbs being good, the electric power steering comes on then off at inopportune times makes steering heavy and difficult to maintain Speed fluctuation the car will jump into gear or rev up to appropriate gear.
Power steering keeps making a whinning when vehicle is not turning or in motion. Having continuously fill reservoir with fluid. Causes very hard steering when turning wheels. I ran into my friends vehicle while turning around in my yard from hard to manage the steering. The doors lock and unlock on it's own at any given time. Caused me two occasions of locksmiths to unlock car. Key fob never worked since purchased. 10
