Pontiac G6 Brake Problems

    As like the rest of you, i too am having a problem with my what i thought was an awesome car for me. It first started after 3500 miles. I backed up and heard HORRIBLE grinding in the rear. I took it to dealer and he said "normal sound for pontiac", "it will go away after you drive for a mile or two." Thinking to myself, yea right, you just said that cause im a woman. Well, much to anyone who has owned a brand new car, i was driving appx 69 mph and had to put on brakes as usual and all of a sudden the whole car (all 4 tires front and back) shook and shimmied. Keep in mind that i also told the dealer at 3500 miles that the steering wheel is crooked and should be straight. He said that that too is normal for the G6. I cannot believe the headache i have purchased only 12 months ago. I am now taking it BACK to the dealer and they are (so they say) going to either replace or resurface the rotors. Im hoping they include brake pads. As for the shimmy, could that be alignment and balance? my car now has 19900 miles on it. (6000 were put on from a three week vacation on the east coast. So it has not been used horribly in city. Im just so let down on this. Oh, and the dealer that i am taking it to states that it is USUAL for the rotors to be replaced or resurfaced every 7-10k miles is this true?

    This is a G6 defect and will keep happening over and over. They will fix it a few times then tell you it is a maintenance issue and is not covered. GM will not back up this car. I spend over 1000 on performace slotted/drilled rotors for the front and standard for the rear and it has fixed the problem. Of course after finding out about the problem I made sure I didn't use a GM business to fix it. I now love my G6 again.

    I have 15,000 miles on my G6 and my brakes a squealing ever so slightly. Just a little bit, here and there. It is really not bothering me yet, because its only now and then and quietly. But, at 15k, I would think it shouldn't be doing that. I am not hard on my brakes at all.

    I am taking it in to have my transmission looked at closely. I am telling them to take all the time in the world to look at it. Drive it and inspect it. I feel that there is something not entirely right for a car that only has 15,000 miles. However, I do plan on driving an identical car, perhaps asking them if I could drive one for the day to see if there are any differences. I am just worried, they will tell me they have found nothing. Its normal. I do plan on typing up a symptom sheet and give it to them.

    I am just nervous to look as though I am making it all up.

    I bought our G6 last year it is a 2008. We have had brake problems since 19,000 miles. They began to feel "spongy". We have taken our car to the dealership 3 times so far. We have 24,000 miles on it now. They have "resurfaced" our rotors 3 times!!!!!! And they now say we need brakes as well. The rotors are warping when they get hot. We just picked the car up on Wednesday and it sounds AWFUL!!!!! I cant even believe that they would let us take it from the dealership sounding that bad. They tried to say it was the way we drove the car..etc. I wouldnt even let them put brakes on it...why put brakes on it when the rotors are garbage!!!!! I called GM and filed a complaint. As I can see from the forum here...I am wasting my time..I guess. $600 at the auto store to buy the correct rotors and brakes at our expensive..and it will void the warranty..because I will be damned to pay the dealership to fix it! :lemon: :mad:

    I am sure you have read about the issues on my G6 under the transmission forum.
    The dealer will have had my car for 2 days now, and I hoping the give me some news on what is going on. It better be the something really is wrong. Something I can work from.

    Well I am so sorry you are having alot of problems with the G6. I had to many problems that I wanted to burn the damn car up. Yeah its always the brakes, rotors, the power steering, the sunroof, the cd, the blower, and the front of the car roars. I started having problems with my G6 nearly a week after I leased it. I leased my G6 GTP back in 2006, and it gave me problems every since. I did file a lemon law claim and got a huge settlement, but I knew I wasn't going to purchase the car after the lease ended. The most biggest problem I had was the gear shift. It would practically get stuck in park and never come out, until about 5 to 10 minutes, which is unusual. I took it the dealership and they tried to fix it, by replacing it, it still kept on doing the same thing. I got so fed up that I traded it in for a Torrent last year. All I can say, you better get rid of before GM files for bankruptcy and aint to telling what may happen. But know I'm thinking baout purchasing a Nissan this time. Their cars are much better than the American cars.

    Well, its not that I have had a lot of issues, but having a Catilic Converter get all clogged or bad after only having my car for 13mths, that is sort of a sign! They are replacing it though, they asked me to either come pick up my car or drive the rental. The part comes in Tuesday afternoon. I asked around (dad, friends), and I was told to keep the rental. GM can front the bill, this is not my problem. Plus, I don't want to aggravate the issue more. They are putting me in this position not me. This has been the only real issue, a bigger issue, the engine has never felt truly right from the beginning.

    Also, I am not sure the catilic converter even controls how it shifts through the gears. Effecting the performance, but a rough shifting transmission? They said they had to drive it a couple times to repeat the issue, but I drive about an hour each day back and forth to work. I would certainly know if something was up.

    I do plan to take the car back if it is acting that way again when I get it back. I feel this way..... I pay too much a month, and work too hard for my money to be unhappy with a leased car. Luckily I have an awesome and low payment for my model of car now, so I will transfer the lease to someone else once they have checked everything out.

    I am a little sad and disappointed, they put together a great package, and a great looking car, but get behind the wheel, and it just leaves you feeling with something more to be desired.

    I plan on getting out.

    I am curious if the calipers might be the root of the G6's (and other Pontiac) problems. As I understand it, Pontiac calipers do not move straight in and out but rather they turn a corkscrew motion. It seem logical that if the inside of those threads became rusted even slightly then you would have pads constantly applying pressure to some extent against the rotors. This in turn would lead to premature failure of all parts as well as reduced gas mileage. Would also explain the situations when people had their rotors glowing red on the highway!

    I have also just had my rotors turned by the dealership for the 2nd time (bought at 17K currently at 33K) and also need pads. I am considering trying to find aftermarket calipers as well. Anyone have any thoughts on this?

    I am curious if it is normal to have slight brake squeeks or slight squeal intermittently on my 08 G6, which had only 16,400miles on it. It seems like it is when I slowly push down on them at a slower speeds. Not all the time, but often enough to wonder if its normal or not.

    I am not a person that is hard on my cars engine nor the brakes... I drive mostly highway, less city. However, makes me wonder if it is normal. I had this on my 06 Accord, but it was later on at about 25,000 or so when it every now and then showed up.

    Some of this normal?

    Well, I finally got into the car and found I was wrong about the calipers. They do move straight in and out. I was also pleased to find that they were in good shape; no rust and moved quite freely. I guess my theory was wrong, at least in this case.
  • jeffsayersjeffsayers Posts: 15
    Could be from lack of lubricant on moving parts, but it seems this car has a history of chewing up brake pads and rotors so you should probably check them out. The inboard pad on the passenger side gets the most wear so check that out first.

    I may have solved my brake/rotor issues. So far, so good.

    Apparently I've been lucky, because I didn't have to replace brakes until about 45k on my 2006 G6. But I was doomed after that, of course.

    They said my rotors were absolutely fine when I replaced the front brakes - I made sure of that.

    The problems started immediately. Squeaking, squeeling, etc. I think they had to replace my brake pads four times. Then they told me my rotors were bad, but not before accusing me of being "hard on my brakes." (Then I reminded them that the first set lasted 45k.)

    So, here's what I discovered after lots of Q&A with mechanics and owners:

    I had my brakes replaced at Goodyear. I usually ask for "good" brakes, a step or two above the cheap ones. Apparently that was a bad idea, because Goodyear installed CERAMIC brakes. Until now, I didn't know the difference. Well, apparently ceramic brakes need to be paired with rotors that are a bit tougher and not so worn-out. So, at 45k, putting brand new ceramic brake pads on my old rotors was a really bad thing to do - my rotors didn't have a chance. I have a feeling if I had put the cheapest brake pads available on my car, my rotors would have been fine for a while.

    Goodyear, of course, denies this. They won't take the blame for putting incompatible brake pads on my old rotors.

    And, interesting -- My mom owns a Saturn Vue. She's at around 35k. She had to replace her brakes at the same time that I did. She went to a different shop but had the exact same problems. Literally, the EXACT same problems. In fact, she's still dealing with the problems. I think the Vue has the same rotors/brakes as the G6.

    So after resurfacing my rotors twice and burning through 4 sets of ceramic brake pads on my G6, I finally decided to take matters into my own hands. I did some research online, spoke to some mechanics, and came up with a plan.

    Since our G6's have problems with overheated rotors, a mechanic recommended a drilled/slotted rotor. Since I am sour on ceramic brakes, I went ahead and bought the brake pads that were recommended for the new rotors. I ended up purchasing EBC 3GD Sport slotted and dimpled front brake discs. Then I purchased the "Greenstuff" brakes that went along with them. (I purchased online at Summit Racing.)

    My order arrived and I took everything to Brake Masters and had them installed. Additionally, I made sure to specfically tell them to NOT use the electric tool to tighten the lug nuts. Apparently the number 1 cause of overheated rotors is over-torqued lug nuts. I didn't want to take any chances.

    So they installed the new brakes and rotors. When I paid for the labor, the manager openly told me (without me asking) that he's not sure if what I did is going to solve my problems. I never told him I had a problem, so I inquired... He said the Pontiac G6 is the worst car in the world with brakes & rotors. He thinks Pontiac has a huge problem that they're going to have to do something about.

    Anyway, I am staying positive...

    I drove out and couldn't believe the difference. The new set up is absolutely SILENT, I have NO VIBRATION, and my car STOPS perfectly.

    I've driven it several hundred miles already, and I have absolutely NO PROBLEMS with my new rotors and brakes. I'm convinced my car is cured. Whether it was just the rotors, just the brakes, or a combination of the two - whatever I did WORKED.

    So I wanted to get on these boards and share that information, just in case there are others out there who are ready to do some brake/rotor replacement, or who are having problems. So far, so good with this setup.

    If my status changes, I will certainly log on and let you all know. I guess there's a good chance I may encounter problems in a few thousand miles... But I can't imagine why?? If my first set of brakes/rotors (the cheap junk that Pontiac gave us) lasted 45k, I can't imagine why replacing BOTH parts with brand new, better-quality parts won't last just as long, if not longer.

    Hey Jenny,

    I think i have same problem as you HAD.

    I have 06 Pontiac G6 95k. I just bought it and i really love it.

    One thing that i notice from beggining is that on my (driving) side there is this little "thump"sound in area where the tire is.

    I am almost convinced that my rotor /caliper are not doing good together anymore.
    Car was sitting at the dealership for who know how long and the corrosion must have done it.

    What i am interested about is where and and what product did you get to SOLVE this problem ?? How much should i be looking spending for this.

    THanks!

    I was one of the original posters and this is what me solution was. First I had to get my drivers side wheel bearing done for over $300. That stopped the loud roaring sound and vibration coming on the front end. Next I had to get my brakes pads and rotors replaced for over $300 which stopped the jerky (kinda like the brakes were skipping) feeling while stopping. Lastly I had to get new tires at over $350. The continental tires that came with my brand new G6 had little or no tread left. Now my car runs almost perfect. The breaks are still not as smooth as I would like but I did hear that the G6 need high performance rotors and ceramic pad. So next time I need to do rotors i will buy the slotted ones. I bought my 2006 G6 GT new and should not have had to do all this work. Pontiac should have known this car need high performance material to run smoothly! I love my car but i am disappointed in some of the manufacturing decisions. :mad:

    You people are too hard on your brakes. Just traded My 04 Malibu with 44 K and brakes were about half worn and no warping. I figure they are good for at least 80 to 100 K . Treat them like a women, nice and gentle.

    That's fine and dandy for a Chevy, but we are talking about Pontiacs here. Secondly, I don't care how dang hard you are on brakes; in no case should they need to be replaced at 20 some thousand miles. :mad:

    Pontiac=high end performance? I am not so sure. No offense.

    Pontiac, Chevy, Saturn, etc, I am sure they all use similar parts, if not the same.
    All GM products. The new malibu and G6 use an incredible amount of similar or like parts. In my book, all those brands are the same, but with different look or title.
  • gonogogonogo Posts: 869
    Same car, no difference. I traded for a 09 G6, I feel I am still in my Malibu. Everything the same except some sheet metal and badge. Turn it up side down and all Malibu.
  • bxgirlnscbxgirlnsc Posts: 12
    I am no mechanic nor am i a speed racer. my mechanic reccommended i get high performance rotors to prevent the rotors from warping soo fast. he say he sees that a lot with the g6. i am not hard on my brakes. but i don't think you can compare a malibu to the g6 with a v6 engine.
