Pontiac G6 Brake Problems



  • I own a 2008 G6 and am having the exact same problem with my brake lights. I had them worked on 2 weeks ago and the same problem is happening again. I plan to contact GM to see what they plan to do about this issue. I work with a gentleman who's daughter also owns a G6 and is having this same problem as well. Will keep you updated...thanks.

    It's usually the BCM connector, need to be serviced with dielectric grease. GM has a TSB on it.
  • I have had to take my 08 G6 into the shop twice with this problem, only helps for a couple of months then starts happening again. It's getting to be very frustrating at this point. I have to call again for the third time tomorrow because it started up a few days ago.

    Believe it or not ,you can blame EPA, can no longer plate pins with cadmium. Why they can't come up with a something else, I have no idea.

    I apologize for your inconvenience. Have you spoke with GM Customer Assistance? Has the dealer involved Technical Assistance? If not, I might ask them to do so. I look forward to your response.

    Update, now 29K and brake pads still good, gotta like these brakes.
  • Hi, I have a 2006 Pontiac G6. At random times while driving i feel that i need to give my car more gas to go. When i take my foot off the gas my car will brake on its own and my brake pedal feels as though it is locked. This could last a few minutes to an hour. When this happens I pull over and turn the car off. When i turn it back on I hear a clank type noise up front by the by the odometer. Has anyone else heard of such a thing? This is getting very frustrating because i took the car to the dealership i bought the car from and they took it to 2 different places to be looked at but no one has ever heard of my problem plus my car wont act up for them. I have also taken my car to 2 places as well and still nothing. I was told to bring my car in while its acting up but my problem is that im never around a mechanic when it happens or they are closed. Im also afraid to drive when my brakes lock up.

    A friend said maybe my calipers are sticking. Does this sound like it is something to look into? Any help would be appreciated.

    Thanks in advance!

    Sounds like you are having problems with your anti-lock brake system. I would start by having the brake fluid replaced, dealership can do it and cycle the anti-lock system to flush out the old fluid in that unit. Since having anti-lock brakes I do mine every 3 years, the fluid will absorb moisture.
  • I see that you've already been working with your dealership towards resolving the brake concern you're describing. If we can follow up on this for you, please send us an email with more information, including your name/username, contact information (phone and address, please), the last 8 digits of your VIN and current mileage, and the name of your preferred dealership.

  • Thank you for replying! I apologize, but im not good with car terms at all! haha I did have my my brakes bled when this first starting happening. Is that they same thing as having my brake fluid replaced as you suggested? The dealership i got the car from has had my car all week... taking it everyone to see if it will cause them the same problems and no luck yet. I will call them in the morning and mention the anti lock system and see what they say. I appreciate you taking the time to reply.

    Brake bleeding could be complete fluid replacement, if done by dealer they have the Tech 2 to do the ABS module.
  • I own a 06, G6, bought it new got a smashing deal so figured why not. Replace intermediate steering link @ 50,000 miles due to this annoying clunking u all are hearing when turning. Replaced brake pads and rotors turned for the first time @ 85,000 miles aaannnndddd, had front brake issues ever since. I think if you put ceramics on then definately have to go with heavy duty rotors or crossdrilled rotors which you might as well for the cost of heavy duty rotors. Also, all brake pads are not created equal as well as rotors. When cars are manufactured where ever that may be all parts are not manufactured in the same location, hence outsourcing. So think about it like this, your care and most of it's products where made by the lowest bidder, where ever that may be. First off I haven't given a lick about pontiac and them willing to stand behind a car they build ever since the intermediate steering link had to be replaced. That was such an obvious engineering flaw it's rediculous, you might as well not even spend the money for the warranty. The brakes I am yet to figure that one out but, if i find something that works, I'll let u all know, leaning towards ebc rotors with the green pads after doing the research and I am going to bleed the sh&% out of my brakes when I put them on. As for comparing one carto another with the same problem, no disrespect but don't think you can. However I do own a Dodge Ram 2500 and they stand behind there product, no problems and warrenty is bumper to bumper including electrical malfunctions and electronics for 8 years 85,000 miles, now that's not a bad warranty. And noting that they let you set up your warranty however you want it within certain parameters shows that they know there product is quality and they want it to continue to be quality. Warranty work done twice for recalls, OMG did you hear what I just said RECALLS. I don't think the later knows what that word is or means. Sorry I'm just pissed in a world of technology that we live in brake issues should be a thing of the past besides normal wear and tear. Just trying to make a buck I guess, just like big oil, does, LOL!!!

    Wow 2010, old history. I never had a truck with bad brakes, why because they are heavy duty do to GVW requirements.

    34300 miles now on my 09 G6, last brake check 29 K , good.
    Recalls are for safety items. Now customer satisfaction is another story, GM is not very good at that.

    34355 miles brake pads still excellent.

    My daughter has had issues with the brakes every year. Last year we completely replaced the rear brakes and just last month we did the same with the front brakes at Firestone. We were planning a trip so everything was done with new parts. Last week her brakes locked up and the car shot straight into the trees. Pretty sure the car is totaled. Fortunately, she was not injured (amazing after seeing the car in the trees and all the damage). Nationwide is inspecting the brakes since we had them serviced last month. :sick:
    Now, other than the brakes, the car was wonderful. We both enjoyed driving. Does anyone know if the poor brakes are not an issue with newer models? What about 2008 and newer models?
  • We're glad that your daughter is okay after the accident, holzer! Hopefully you'll be able to find a great replacement vehicle for her!

    All the best,
