Pontiac G6 Brake Problems

  • Well of course two days before the appt with the dealer the noise stopped. Brought it in anyway and they are fine. NO CHARGE YEAH! I am not technical here but will try to remember what they said,

    Front brakes are great, back at 70%. With these types of brakes compound forms and you will hear that noise until it wears off.

    Sorry I know there is a better technical description but I have no more brake noise, perhaps it could be grime that built up.

    I do recommend the car actually, I love mine..its roomy, good pep and decent gas mileage. I am sure as with any car the wear and tear affects the performance.

    Good luck.
  • Has anyone had a problem with their brake switch? When I break my break lights turn off and when I accelerate the break lights come on. I've been to the dealer twice. They said it was the brake switch and replaced it. I thought I was all fixed but then I noticed it again driving late one night I could see the brake lights reflection off of some signs and I was accelerating. I went back again and they "recalibrated" the brake switch. The brake switch also affects the cruise control (meaning it doesn't work at all), the brakes don't seem to be ABS. They're not sensitive like some other cars that I've driven with ABS. Has anyone had this problem? It's very dangerous for me to drive my car like this but I don't know what to do.

    I have been having the same problem. I own a 2007 Pontiac G6. In the past week and a half I have had my car into the dealership TWICE. The first time they said they could not find a problem. The second time they said it was the brake switch and "said" they replaced it. I was told over the weekend by some friends that were aware of my problem and was following me to see if the problem was fixed that the car was still having the brake light issue intermittently. This morning I was pulled over by the local police and was told my brakes were not working properly (luckily when I explained my situation I was not ticketed for the problem). I have called and made an appointment with the dealership AGAIN to have the issue checked into. I feel your frustration. I have to have a car for my job and do not feel I have a reliable car.

    I have owned GM products (Buick, Pontiac and Chevrolet) off and on since 1969, and the one thing they all had in common was brake "surge" due to warped rotors.

    After being told that it was due to improper wheel lug-nut torque, I purchased a quality Torque Wrench. To this day,immediately after getting a new car home, I loosen the lug-nuts and then re-torque them to specifications in the owner's manual.

    I have owned Chrysler, BMW, Toyota, Nissan, VW and Mini Cooper vehicles as well, and NEVER, EVER had rotor warpage on anthing other than GM vehicles, so I would hazard a guess that it isn't my driving style or environment causing problems.

    So, I shared your pain on this issue. However, it could be much worse...Check out the 08 Saturn Sky Red Line model's brake problems, here on the Edmunds forums...you might be glad that rotor warpage is the only problem you are having!

    Sounds like my story has been covered here. I have an 2005 G6 which I totally love!! EXCEPT my roters keep warping...... After the 5th trip to the dealer I finally find a service manager who has the balls to tell me of the G6 issues with roters. I dont want to throw more money at this unless I know it will fix the issues. He suggests I go with a after market roter that is a slotted/drilled style. Looking at about $500 for front roters, brake pads and labor. If this works I think its worth it but I am so unsure after reading of all the problems. Does anyone know if this has been a good fix...I am not looking for a bandaid that will end up costing more down the road.

    I can only speak from my experience...any standard GM replacement rotor is going to warp. Warpage is not isolated to the G6...

    While I never invested in aftermarket rotors on any of my GM products, the simple fact is that I never had these issues on any non-GM automobiles, so I know that rotors can be made that will not warp under normal circumstances.

    I am sure that you can find suitable aftermarket rotors at a reasonable price, but I would double-check the warranty covering warpage. Also, seeing as how you have been abandoned by GM, I think I would let a different service provider do the work.

    Try www.brakeplanet.com for a start. There are many others you can find on Google, not to mention local brake/mufflerrepair shops in your area..

    Good Luck!

    I just started experiencing this problem. Did you ever get this resolved? Was it the break switch? How many G6's does this have to happen to before it's a recall issue? I will never get another G6, have had a lot little things go wrong. Got mine in 2005 thier first year.....no store sells the wiper refills anywhere....NOBODY!! had to have the dealer order them for me.....$62.00...unreal.

    I've been having same brake light issues and cruise control interruption. I've taken it to two places and each time they say they don't find a problem and it will work fine for maybe a week. I have it scheduled to take to take to a third place. I've filed a complaint with NHTSA. It's obviously not an isolated fluke problem and a recall needs to happen. The complaint process is fairly easy and if enough people complain maybe they will force the issue.

    As far as the ABS, I do not believe it was a standard option at least on my 2006. Mine does not have it, and I can't say I miss it.

    I get repeated check gas cap messages. Originally, I had the gas cap replaced and the check engine light that resulted reset. Now I periodically and inconsistently get the message. It doesn't always happen, but appears temperature related (40-50 degrees). After about 3 or 4 check gas cap messages, the check engine light comes on. I reset and the process repeats. Anyone get a similar problem.

    I just started having this same issue. Brake lights reversed on the 2005 model g6. I am going to take it to the dealership on monday. This is very dangerous and should not be happening on a 3 year old car. Has anyone gotten this issue resolved?

    I purchased a new 07 G6 just over one year ago, had it in the shop numerous times within the first 3-8 months concerning the brakes - noise, stopping issues, feeling like the brake was competing with the accelerator when coming to a somewhat sudden stop. They replaced rotors and/or pads, kept saying it was an issue that GM might deal with IF we continued to have problems and brought it in several more times. Recently, the "traction control" light came on the stereo display and the brakes immediately failed - even the emergency brake wouldn't stop the car going less than 10 mph. It hit the car in front causing only a minor 1/2 inch scratch on their bumper - but, must have hit the "crumple" zone on my car as the hood crunched like aluminum foil and the radiator crunched enough to drain all fluids. Thank Goodness no one was hurt! I am seeing a lot of brake-related issues with the G6 - so, I'm curious to see if anyone else has had actual failure or that stop-go-stop-go-stop-go action with braking (like it is turning on and off or - as noted above - fighting with the accelerator). GM is sending a professional engineer to determine what happened - so, I am hopeful that they intend to correct the problems. If not, I feel I will be forced to sell the car to ensure my family's safety.

    I ended up going to Brake Team and having them install non GM Roters - Slotted and drilled high performance roters and new pads on the front only. $800.00!!!!

    I love my G6!!! I hope I am done with brake problems. Brake Team gave me a 3 yr 36000 warranty. Re-checks every 12000 miles, free replacement if any issues (NO TURNING)

    If you haven't done so already, I would suggest you make a report of this incident using the NHTSA web-site.
  • I'am new to the forum I have 2007 G6 GTP I was originally looking to find out if any one was having problems with the transmission fluid leaking.I run across this post and I see I'am not alone on the front discs being warped called dealer friday about tranny and I asked about the discs he played it off like it was just time for new ones at 23,000 miles I know better but I am taking it in for the tranny on mon. I will drill him hard about these discs as well as the clear coat starting to peal as well. I will report any findings when I get the car back.

    I have a 2006 G6 and I do love it, when I can drive it. I have had it in various shops and the dealership several times, in fact, it is in the shop now! My problem, so the mechanics think but can't prove, iscar the ABS. I could do 75 down the highway and one of the tires will shake, lock and then cause all 3 other brakes to lock completely. The only way to disengage is to turn the car off, disconnect the battery to reset the ABS! The master cylinder has been replaced, pads replaced (to ceramic to reduce noise), lines, sensors, rotors recut and it was on an electrical diagnosis.....they found nothing! I drive it 3 miles and the car just stops completely on its own, no matter what speed I go. I bought an extended warranty but they won't acknowledge it because they won't recognize the original miles and then add the warranty mileage.
    Who can I hire to blow the car up? (kidding) I love my G6 but investing more $ into something that can't seem to be fixed is a waste. I will never buy a Pontiac again and can't wait to find a way to trade it in, no matter how in debt I wind up being.
    Would love any advice if you folks have any! Please!
  • With 33,000 miles, I need my third set of rotors....dealer wants $460...I ordered Power Slot Cyro-treated (part# 8278CT) for the front for $230 (set). Let you how they work.

    I too keep getting the "Check Gas Cap" messages....Now the engine light won't go off - I brought it to a mechanic - apparently the engine checks itself automatically - there is a problem with the pressure in the tank when it does the check so on comes the light!

    I was also told to only purchase a dealer gas cap - not from an auto store. They reset the engine light and I went on my way. I know this isn't the end of it.....
  • Have you talked with Pontiac Headquarters about the rotors?

    My G6 has 12,000 miles and will replace a set of rotors soon.

    You say, "THREE SETS OF ROTORS IN 33,000 MILES!" Wow.

    I guess that means GM ROTORS for the G6 are only meant to last for about 11,000 - 12,000 miles!

    My G6 Rotors are always in a state of "rust." Always cutting them.

    Rotors should last for 50,000-70,000 miles so I am told!

    If Your Dealer reports to Pontiac Headquarters that the rotors were defective - then the perhaps the rotors can be replaced at Pontiac's cost.

    However,, the new rotors will also only last about 12,000 miles.

    This is outrageous! Whatever can the consumer do?
    With GM cutting back on production and jobs this past month - I don't expect them to admit that there is a problem and will not recall the rotors.
    It is up to each individual to fight.

    I already talked to Pontiac Headquarters.
    Now, I am going to find my State Consumer Protection Agency and see about a LEMON law thing. Then an Attorney for the aggravation and dollars lost on a brand new car. Let GM pay the attorney.

    I wonder how many people are out there who have been buffaloed by the dealerships into thinking replacing the rotors at 12,000 miles is a "normal" part of maintaining a car? :mad:

    Anyway, would be interested in knowing how the Power Slot Cyro-treated(part#8278ct) for the front rotors at $230 set work?

    Please update. :lemon:

    First off, I lease my 08, and if they ever feel that I need to pay for new rotors after only 12k miles, Heck no! I am with you, there is no way! The whole point for me to lease is to get a new car and not have to worry about problems like that. 12k miles is nothing, and I on a lease should not have to worry about anything remotely extravagant within my lease. So they would be here from me, if the dealer tried to pull anything I would simply go off on them. Essentially that would be GM revoking on their end of the lease agreement, because as a consumer, if I am up on my upkeep of the car, I am holding my end up, and replacing the rotors is not on that list. That would be like them saying you need a new timing belt or new exhaust at 12k miles, but if its defective, then its not because of me. See, I am on my high horse..lol. There is no way I would be covering that, especially since what I gave up to get in this car, it wasn't a car I even wanted to begin with, I like it, but I would be back in an Accord, in a heart beat! Long story.

    :mad: I have an 06 G6 and I have been dealing with this brake light reversal since February 08. The first time they couldn't get it to do it while it was there. So I took it back in May, claimed to have fixed it. It happened again in July, so I took it on the 3rd, claimed to have fixed it and I just took it again today July 31st, claimed to have fixed it. They don't know what the hell they are doing. Instead of calling a GM engineer, they want to experiment with fixes. I'm done working with them and I have called a lawyer. I already contact NHTSA and the Pontiac cust svc line. Make sure you keep your records of fixes and call NHTSA. Enough calls will force GM to find a fix because it's a safety issue. :mad: :lemon: :lemon:
