Pontiac G6 Brake Problems



  • Sorry civicowner, while the brakes on this car seem to be likely to have early wear, they do stop the vehicle. Re-read your words, they seem to support the insurance company's decision. In particular, you had to stop SUDDENLY. Also, to say the brakes worked after hitting the vehicle in front of you, well I would suspect the vehicle in front of you did most of that work!

    Anyway, you are still alive and by ommission of other details I presume the people that got it up the trunk are as well; it could have been much worse.
  • excuse me? You have no clue as to what you are talking about!

    2 joy riders in a beat up truck pulled in front of me suddenly, at the cusp of of an intersection. I had pulled in to post mail. as they had to back up to stay out of the middle of the intersection-I guess they planned to pull out and go, but traffic prevented-this put them close to my car. I have already begun to pull away from ther curb, and had to slam on the brakes. The brakes did not employ in time to avoid hitting them. as a delayed action the brakes worked. Too late, I had hit the side of the truck.
    the ins adjustor took the details, and blamed me without investigating-that is- having the rental car checked. he was too lazy. he was an ahole, and it seems as if he and you would be in good company. cheers.

    ABS brake systems have been known to lose braking power at application. The problem is it is hard to prove.
    Lots of times it is not a accident situation, they just report it to there dealer. Go to the NHTSA site and what's been reported.

    Hi bxgirl,

    I think my G6-06 is following the same pattern.

    The front left wheel indicated something was wrong.

    I had it checked by Midas , Canadian Tire. Midas said wheel bearing is not doing great, but suggested to just get tires ( i was suspicious)

    Canadian Tire guy just said my tires were not rotated so uneven wear was his explanation ( he rotated the tire to the back)

    10 months later:

    I have been experiencing vibration/rumble in the same front left wheel when i brake (even with new tires installed 2 days ago)......

    The question to be answered: Is it rotor that is bad, or wheel bearing ? Or BOTH !?

    In case I have to get rotors , brake pads,bearing ...can anyone suggest what/where should i get something thats going last more then a 1-2 years.

    I got a quote from Midas for 384$ rotor + pads+labor ( mid value option)..... is this ok?

    Thanks pontiac "fans".

    Well sounds like your rotor. My car was making that noise even while driving. So far I have had to get my right wheel bearing and a tire rod. My rotors were also replaced now my car drives and sounds perfect. Try resurfacing your rotor first then get them replaced if that don't work. this is a high performance car so I would get the best rotors I could afford. All in all after the front end was fixed I love my g6 and wouldn't trade it.

    I have also found this car goes through tires fairly quick. If your tires don't have enough tread the abs will kick in (sounds like grinding brakes) don't fix your abs (like I was told by mechanics) just get new tires. It helped me.

    Remember me? I think my first post was somewhere around #98, if you want to refresh your memories, almost a year ago. Sorry I didn't get back here sooner to respond to some of you who were inquiring about the brakes and rotors I purchased. They have met their demise, however, so it probably did me no good. (Read on.)

    My Story: 2006 G6, currently with 76,400 miles.

    Yes, I drive a lot, but I also take very good care of my car, and, like some of you have mentioned, it's all long-distance open-road driving in the middle of the day with no traffic. And I'm easy on my brakes. Probably overly-easy on them after having two Pontiacs! (Prior to this G6, I drove a Sunfire over 100k miles - had similar issues with its brakes and rotors, although not quite this bad.) Should have learned my lesson!

    To you people who say it's my fault - screw you. I can only wish this upon you so that you can learn your lesson. There are so many consumer complaints about this, it's absolutely ridiculous. And every time I take it in, no matter where I take it, everyone tells me that it's a known G6 issue. So nobody is going to convince me this is my fault.

    Let me start by saying I LOVE my car. It's the brakes, rotors, and front end alignment that I hate.

    And, this car has had the I-Shaft "steering wheel clunk" problem since under 20,000 miles. It was replaced twice, I complained about it numerous times after that, had it re-lubed once (because they told me it was a defective part AND a defective replacement part, so no sense in replacing it again!), and then I just GAVE UP. It just clunks....and clunks, and clunks... And don't think that the re-lube is going to fix it. I had it relubed once, and the first turn I made out of the lot pretty much BROKE it, to the point where the dealer had to replace it AGAIN with another defective part. So screw the re-lubing. Just forget about it and get used to the clunking. It's not going away.

    At 21k my brakes were already in the yellow.

    At 38k, I replaced the front brakes AND had the car aligned.(Anyone else want to complain about the alignment?)

    All of my problems ALWAYS start after the first set of brakes are replaced, so let the games begin!...

    At 50k, had to resurface the rotors.

    At 54k, had to install new rotors AND new front brakes.

    Now, let me explain what I did: For those of you who think that installing high performance, extra cool rotors and special brakes will make some sort of difference... I purchased high performance, cross-drilled rotors, and the brakes that were recommended to go along with them. Figured... Problem Solved! But, no... keep reading!

    At a little over 54k, I had to do another alignment.

    At 64k, another alignment was recommended and performed.

    At 71k, brakes are in the yellow again.

    And now, today, at 76k, had to resurface the new rotors!

    I can guarantee you that in a couple thousand miles I'll need NEW rotors and front brakes AGAIN.

    My high performance rotors lasted 20k before they needed resurfacing. Some of you might think that's better mileage than stock, and it might be, but it's still absolutely ridiculous. It appears there is a 3-year warranty on these, so I am hoping it will be honored.

    I thought I had my problem solved. So for those of you who think you are "lucky" because you've replaced these things and you think you aren't going to have any more problems... HA! to you! It'll sneak up on you and bite you in the [non-permissible content removed], I promise.

    It's NOT an issue of "cheap" rotors.
    Let me quote a mechanic from another forum: "It's not the part, it's the design on the vehicle that warps the rotors."

    The clunk you all describe - It's a defective I-Shaft. Period. And good luck with that!

    So, let's summarize what we can do: OR 1-888-327-4236 -- FILE A COMPLAINT with the NHTSA -- FILE A COMPLAINT with the government

    1-800-762-2737 -- Call Pontiac and FILE A COMPLAINT

    I just spent another $88 to resurface my "high performance" rotors, and I am PISSED.

  • gonogogonogo Posts: 879
    First off the clunk is an easy fix, even a women can do it.
    I owned a 04 Malibu Z, body same car, with 40K not even half worn brakes. Now have a 09 G6 with only 12 K, so not sure how the brakes are doing. Pontiac is rotating them for free. Next year I will then be doing the rotation, will then see what the brakes look like.
  • Thanks for the suggestion, I just filed complaints!! :surprise:
  • All,

    I have a 2007 G6 with less than 35K miles. In July of 2009 at 21k miles of driving to/from college and 1 1k trip, there was a groove on the inside of all four (4) rotors. The brake pads had a matching mark, but still had plenty of pad material. The inside of the rotors is protected by a metal shield, so if would be very hard to have a small object get wedged in between pads and rotor. Dealer stated rotors were warped and that caused the groove. How can all FOUR (4) rotors warp in such away to cause the same damage?

    Dealer refused to acknowledge a defect and I was told to replace rotors and pads. I looked on internet forums and found thousands of similar complaints. I looked at (NHTSA site) and found less than 10 complaints. Today there are 21 specific to brake ware. Stop complaining here and complain where it counts, the NHTSA. Look at Toyota and how long that went on before the NHTSA took action. The more complaints at NHTSA, the more likely they will take notice and do something.

    With regards to my brakes. Screw the GM OEM quality. They are less than good. I replaced all rotors with slotted and drilled EBC rotors designed to work with ceramic brakes. I replaced all brake pads with EBC Green Stuff ceramic pads. More than 1 year and 13k miles and rotors and pads look great. Plenty of pad material and the rotors are smooth, clean and straight.

    The manufacturers are taking short cuts in materials and quality to save money and refusing to acknowledge problems until Big Brother (NHTSA) gets involved. Replace your components with high quality aftermarket better than OEM equipment and complain, complain, complain at
  • gonogogonogo Posts: 879
    Curious, how did you find grooves behind the shield of all four rotors, no one ever looks there.
    As for NHTSA doing something about brake & rotor wear good luck, brakes are normal wear items, fast or slow.
  • gonogogonogo Posts: 879
    My 09 G6 brake experience.
    I just received my last free service from Pontiac, they did a complete inspection. 18K miles the front brake pads were good and the rear pads were excellent.
    I will do the next tire rotation myself and will make another report, at about 25K miles.

    2005 g6 with 21,250 miles (yes, I really don't drive that much, because I live in the city). I noticed car would lurch forward, then pull back slightly at full stop for the past 4-5 months. Ignored it, but, this weekend I heard loud grinding for 2-3 seconds when I was pulling out of parking space. Finally checked internet, saw all these posts and brought car in to dealership. End result - all four rotors (OEM) had to be resurfaced; had all pads replaced as well (dealer had brake "special"). That came to about $450. I already know that in 10k-12k miles I'll be coming back to redo the rotors again, or get a new car (lol!). GM dealer's brake tech also said that the brake fluid is "dirty", wants to flush and replace all brake fluid. That's about $150+. Probably will do it.
  • Well Orion, the timing is certainly on par for a brake job. The lurching you describe sounds weird, like maybe something in your transmission to me, but I am not a mechanic so... However, I would STRONGLY recomend getting a second opinion about your "dirty" brake fluid.

    For what it's worth, I myself just gave my front rotors with less than 50K miles their second turning this past weekend. The pads (2nd set) still had over 50% left. Expecting nothing and not being let down, I called the dealership and asked if GM still says this is normal with a straight face. The service coordinator actually laughed with me about that one. So, I have come to the conclusion, just plan to replace brake pads and turn rotors on every fourth oil change as part of your maintenance plan.

    For those that go to the shop, I would suggest buying a jack and a small socket set. The job takes about an hour to do and I'm sure their is a tutorial somewhere on the net on how to do this. You know, if GM can't fix this, maybe they can make future models so that you don't even have to have tools to change the brakes, sort of like changing a tail light. :P

    I have a 2007 Pontiac G6 with 45xxx miles with the same issues with the brake lights coming on while driving and shutting off when pressing on the brake petal. I have replaced the brake switch, that worked for about 5 days! I had it towed to Dugan Chev. this morning.. Still waiting for them to look at it and tell me what they "think" is wrong with it.. I also called GM yesterday about this issue.. They gave me a case number and are following up with calls to me and to the dealer to tell me if this is a fix they will cover.. If they will not fix the car I will leave it at the lot! I'm not putting thousands into a car that when I bought it I was told that the lease would cover everything! I will update as I find out what they decide to do with the car.. Please if you have had troubles since the last posts on this matter post your issues and fixes.. I am also interested in getting a petition going to GM to get people with these troubles covered! It is a dangerous safelt issue and should be recalled!!
  • After filing a complaint with NHTSA, we (I credit a concerted effort through this forum) did get a recall for the 2005-2006 models, which is tantamount to them putting some gunk on a connector. See NHTSA CAMPAIGN ID Number: 09V036000. This was too late for my '06 model. After nearly getting rear-ended several times, we had to get some controller module that controlled the switch changed out and this did fix the problem. It sounds like the same problem. I don't think the recall posted until 2009. Good luck!
  • gmcustsvcgmcustsvc Posts: 4,251
    Have your issues been resolved? A petition is not the way to go to make GM aware of an issue. The best way to go about it is exactly as you did, call GM and set up a case for the issue. This is one way GM finds out about widespread problems is by customer calls into customer assistance. I look forward to your response!

    I don't understand how GM could NOT be aware of all of these problems by now.
  • gonogogonogo Posts: 879
    Just rotated my tires at 24 k, Pontiac has been doing them for free one year.
    Pads and rotors are good, little wear, reset TPMS, easy to do.

    Please don't be fooled by the "concerned" customer service rep. If there was really concern, perhaps they should convince the lackluster company they work for, to back the product they sell? I am incensed with GM and the pathetic lack of concern for their "valued customers"
    Having tried to shop and buy North American made product, and owned or leased, 7 General Motors cars since 1999, I recently had two G-6 cars. A 2005 and 2008 Gt coupe. Same brake and rotor issues for both, every 12,000 km they would require service. Just in to have rotors machined today. Third time in 48,000 km. The OEM parts are garbage, suggest you by your own after market parts and keep the dealer out of it, since they are in bed with Corporate and cannot offer you the proper fix, which is don't buy a GM!!
  • 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.
  • gonogogonogo Posts: 879
    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.
  • gonogogonogo Posts: 879
    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.

    Have you spoke with GM Customer Assistance? If so, what is your case number? Please feel free to email me. I look forward to hearing from you.

    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!
  • gonogogonogo Posts: 879
    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.
