Reference NHTSA id number10850549--loss of left front speaker chimes and radio sound --ok after both speakers were replaced--after a while problem returned intermittently on the left front speaker again-- finally had an "epiphany" and removed corrosion on the harness pigtail connector which pushes onto the left front speaker lugs using Q tips, small screwdriver and great care using contact cleaner liquid from a small 2 ounce spray can of deoxit-D100 made by caig lab Inc of poway, cal.--website www.caig.com--I got my can from you-do-it electronics in needham mass.-tel:781-449-1005--suggestion-after removing the pigtail connector from the speaker place an old towel between the pigtail connector and the speaker to prevent overspray from landing on anything but the pigtail connector--fortunately the can has a metered "one shot" type spray every time you press the button on the can--after wetting the harness pigtail connector thoroughly I pushed it onto the left speaker connector and removed it after waiting several minutes--then repeated this procedure several times----that was the end of the problem!! the biggest problem was the need to remove the left front door panel to gain access to the speaker but it was well worth it since I listen to the radio a lot. Mostly jazz!! good luck

All chimes have stopped working. Front speakers out as well. Noticed for the last year or so that when the speakers kick out (makes no difference if driving or stationary), the chimes stop working. No "key in the ignition" alarm, no turn signal clicking, no seat belt alarm, etc. When it does work, everything works. When it goes out, it all goes out at once. Now I have to replace the turn signal assy. Because the internal white plastic piece that kicks off the turn signal lights is broken. I have seen many posts for the alarm chime issue from different blogs, but GM still insists they have never heard of the problem. I am now at 99,765 miles on a 10 year old car. I would like to get this fixed.

The front speakers of the radio system intermittently fail to work. At the same time, the turn signals stopped making the blinking sound--both randomly return then disappear again. Also, the cabin air filter makes a clicking sound as it goes from recycled air to letting outside air in.

I have received multiple "important safety recall" letters and post cards from GM and Pontiac urging me to have the defective ignition & start switch that was installed in my vehicle replaced. I received letters when they first acknowledged the issue, letters saying that parts would be available soon, letters when parts started to become available, etc. A month ago I contacted my local GM dealership so they could order the parts as instructed and was told I would be contacted when they arrived. I was informed last week that the parts had arrived and was given a 10am service time for today (9/4/14). I arrived to get the work done, signed the paper to allow them to do the work, and had a seat in the waiting room. Approximately 50 minutes later I was approached and informed that GM would not authorize the work to be done because my car has an "altered" title (it had some front end damage 50,000 miles ago that was fixed 100% with original GM parts). No where in any of the notifications that I received did it mention this. I asked how that could be considering as of February of this year 13 deaths stemming from this fatal design flaw had already been admitted to by GM...I was told it was GM policy and there was nothing the dealership could do about. I asked what front end damage had to do with a fatal design flaw in another area of the car...I was told it was GM policy and there was nothing the dealership could do about. How in this day can a company, that has admitted that they have installed a faulty part in numerous vehicles that has lead to the loss of human life, wipe their hands of the situation because a vehicle has and "altered" title"? I have been waiting to sell my G5 for over a month now, wanting to make sure the next owner was safe and the vehicle was in the best possible shape...but how do I do that now when GM will not honor their own recalls"

Daytime running lamps stopped working on my vehicle. Took my car to a mechanic and he noted that the wiring harness for the daytime running lights and headlights was burnt to a crisp. Could not believe my eyes. My car is factory original and never been in a wreck so there is no excuse for this electrical failure. Daytime running lights are a safety feature according to General Motors and now I feel like my car is less safe because of this problem! help!

Front left driver door speaker in my car will stop working when it rains and has to be replaced. There is a design flaw with this car because the door has a drain tube that is right over the speaker connection and will cause the speaker to short circuit. I normally wouldn't complain about this defect but the front driver door speaker is what is used for the warning and safety chimes that the car is supposed to make when you start your vehicle and while you use it. Now that my speaker needs to be replaced, I have no turn signal sounds, no warning chimes when I start my car to remind me to put on my seatbelt, no warning sound that I've left my key in the ignition, and if my power steering were to go out I'd have no audible warning tone. Very unsafe!

Dashboard lights went awry. Gauge needles floated about giving false readings on speed and gas tank gas level. Lost power steering. Dealer replaced ignition switch & reset the computer for $390.73. Same problem recurred weeks later. 03/18/2014, another GM dealer inspected for $158 & found we need to replace the steering module and column for $1055. I am expecting a recall letter in mid-April. I live in a small town and need to drive my only vehicle although the dealer warned me that the car is in dangerous condition. I hope the recall includes my needed repairs and reimburses me for documented related costs.

I'm experiencing issues with my airbag light. It keeps coming on and off at random times. After much research I have found that many people with the Pontiac G5's have the same issue that I am having and this is due to improper wiring under the passenger side seat of the car. I have contacted the Pontiac dealership and the GM dealership and they both claim that they do not know what would be causing my airbag light to be going on and off and the only way to diagnose the issue is to pay $100 just to tell me whether or not faulty wiring is the issue. I'm paranoid to drive my car because I'm afraid that there could be something wrong with my airbag or maybe it is just faulty wiring. I think this is something that should be recalled since there are so many people with this same exact issue. As a matter of fact there is an entire website devoted for people who have this issue. I can't get my inspection done because the light just pops on randomly. If this is a wiring issue that so many people are having, why isn't GM being held liable for the issue" why is the airbag only covered if it is deployed" this has been going on for a couple weeks on and off and I would really appreciate some kind of response or just a way to handle this. I am a full time student and I do not have $100 lying around to have someone run a diagnostic and then pay even more just to fix a wire.

The engine compartment of my sons 2008 Pontiac G5 burnt up today. It was parked outside our home. The fire department said it was electrical in nature and that it appeared to start in an area near the drivers side wheel. It appears to be a total loss.

The contact owns a 2008 Pontiac G5. The contact was unable to turn the vehicle off and remove the key from the ignition. In order to shut the vehicle off the contact had to disconnect the battery. A mechanic from an authorized dealer was able to assist the contact with restarting the vehicle. The vehicle was then taken to an authorized dealer where the contact was told that the mechanisms within the steering column fractured, leading to the failure. The vehicle was in the process of having the mechanisms within the steering column repaired. The failure and current mileages were 44,000.

Approaching a busy intersection, my Pontiac G5's brakes failed to work. I could tell the hydraulics systems was working as I could hear metal on metal but it did nothing to slow down the vehicle. The vehicle's cdr showed the vehicle accelerating at full throttle although I know my foot was on the brake pedal as evidenced by the metal on metal sound. Plus a witness saw smoke coming from my vehicle. I was able to turn prior to going through the intersection and aimed for a fire hydrant to try to slow down. It did nothing to slow the vehicle, I tried to turn right to join the traffic direction, but the steering did not work. I then hit another vehicle.
