Pontiac G6 Hardtop Convertible

  • I got my G6 HTC back on 1-3-08. The rattles are gone from the back window but now I have a little wind noise and there is a rattling sound near the driver door or near the driver side back seat window. For the back window rattling noise they used bulletin 06-08-59-003B. Adjusted the rear roof as the bulletin states #B9800.

    I took it back on 1-7-08 to have the rear passenger cup holder replaced. While I was there I talked to the service manger and told him that the top still rattled and he said that the car was designed that way and that they have done all they could.

    I am not satisfied, so does anybody know what course of action I can take. Can I file a lemon law complaint.

    Originally I only complained about the bad stereo. Now I too am noticing rattles on the driver's side (I'm probably more aware of it since I read the posts here). Nice Car!! Although this car cost a ton less than some other HTC's, it is still close to a 30K car...........not cheap.. For 30K my expectations are such that the workmanship should not be so shoddy.

    I will take it to the dealer to try to get this fixed.

    One more thing...........I don't live in a cold weather climate. The weather here in SoCal should not have the same effect on the car in the same way that some of the other posts described. But I still have the rattles.
  • :lemon: Hi, I'm sorry to hear you are having troubles. I have a 07 G6 Conv. I purchased in Nov. of 06. I've had the car in the shop 10 times for 47 total days. The rattling is not limited to cold climates. There are several GM work orders out as to how to repair the car. In my case that has at best been a temporary fix each time. Your rattles will start at the windows. Then the overhead connection above the back seat. There is also a problem with the back glass and windows in the doors. The last time my car was in the shop the service manager had to send it to a body shop to have the skin of the interior trunk lining re welded. It seems they are having a problem with the welds in the trunk breaking. It's not a frame issue but causes a squeak in the rear quarter panel. They said it is probably due to the pressure of the top going up and down. They have seen more than one car with this problem.

    If anyone has a copy of the GM Bulletins I would really like a copy !!!!!

    My advice to you would be to make certain you keep a VERY detailed log of the issues you are having. Keep the work orders from the dealership. IF you continue to have troubles follow the Lemon Laws for your state. Unfortunately I can also tell you this is a very slow, annoying process. After the final repair attempt was not completed in the allowed time line I requested a buyback. I am currently fighting with GM to see if we can make that happen. I haven't had my car since Mid October, and we haven't had the hearing yet.

    Take lots of pictures, if possible while the dealership has the car disassembled. Good Luck !! :lemon:
  • I've been reading all the messages about the creaks and rattles with the G6 HTC. I've had those problems as well, but my most frustrating issue with the car is an intermittent problem where the top won't retract - except when I take it to the dealer and it works perfectly! If my memory serves me correctly, both times I've taken it to the dealer because the top wouldn't retract, it had been a relatively cold day for the Austin TX area (50's), but sunny and calm and perfect for a top down drive! Of course the top operated for the dealer and they said there was nothing they could do.

    Today I put the top down (temp in the 60's), went to the grocery store and back home and the top would not go up! I talked to the dealer just last week about this intermittent non-working top and asked if there had been any service bulletins. He said "No." Has anyone else out there had this problem?
  • Ror the longest time I had the same problem for months after I first got my car. It turned out that the latch on the driver side had com completely un-attached and was floating freely. sometimes that latch would be locked most of the time it would not. on times that it would be in the latched position the roof would not open. it took several visits to the dealership to discover this. also once they fixed that problem, a rattle inside the roof went away(apparantly the linkage that controlled the latch. Hope this helps.

    Well, I didn't think 'cold' in LA would have been bad enough to have an effect on the rattling. Maybe I was wrong. We had tempuratures in the 40's - 50's for about a week and a half after I purchased my car. I continously had severe rattling from the rear part of the roof. It has finally warmed up over the last 3 days and guess what? The rattling is completely gone. Interesting!

    If it is a cold weather issue does anyone know why it has such an effect?
  • CALL PONTIAC CUSTOMER CARE AT 1-800-762-2737. MY FATHER RETIRED FROM GM. HE SAID THAT IT IS IMPORTANT TO CALL IF YOU ARE UNHAPPY. POWER IS IN NUMBERS. I OWN THE 07 G6 CONVERTIBLE AND ARE HAVING ALL OF THE PROBLEMS WITH THE TOP THAT EVERYONE ELSE IS HAVING. I AM STILL IN SEARCH OF A CURE. MY STEREO SEEMS TO BE FINE. PLEASE CALL MAYBE PONTIAC WILL WORK A LITTLE HARDER TO FOUND A SOLUTION TO THIS PROBLEM. I THINK THAT THE TOP NEEDS SOME INSULATION OR SOUND BARRIER BUT WHO AM I UH! GREAT CAR PERFORMANCE WISE BUT VERY NOISY.

    I finally took car into service today. They repaired according to GM Bulletin # 06-08-59-003B. Rattles were about 75% gone on the way home............I would have expected 100%, I have a feeling I'll be back.

    The stereo is actually growing on me. I guess I needed to fiddle with it a bit. It's still average at best but at least it seems much more listenable (XM & CD's) than I originally stated. FM sound is still awful.

    You say great car performance. Do you have 3.9 engine? I have 3.5 and it seems to be underpowered, especially on Freeways at a higher speed. I find myself using Manual Mode a lot so I can accelerate better. Car accelerates very poorly with Automatic Trans. If any of you have 3.5 engine, I'd be interested to know if you're satisfied with it's performance.
  • Hi. I posted all my troubles with the G6 earlier. I've since learned something I think a lot of you may like to know.

    The weld on the body panel in the trunk of the car, on the side that the mechanics for the top are located, is coming loose. This is a problem you can't see unless you take all the trunk finish out. If you can stand on the side of the car and push on the rear quarter panel and it squeaks this could be a large portion of your problems. The service manager explained to me that every time they adjusted the top this weld would give a little more, that is the reason the rattles are better for a short while, but always come back. If they fix the weld, maybe that will be a long term fix.

    This problem was found on the final repair attempt on my 2007 G6. To my knowledge there is no bulletin on it yet because a lot of dealerships don't know of the problem. My dealer only found it because my car was taken apart to an extent that most cars never reach. After finding it in my car they have seen it 3 or 4 times in other cars in less than 2 months.

    GM will be buying my car back because I won the arbutration hearing, but maybe this information will help other people not have to go to that extent. The G6 is a very pretty car but GM still has to work out all the bugs.

    Good Luck!

    the amplifier on the g6 is weak as are the speakers-

    all you have to do is get in any other car-even a 2000 grand marquis or an 1999 explorer (my other cars) have a better stereo.

    I agree with you about the stereo but I've also heard a lot worse too. The components are weak but XM and CD's still seem listenable. FM sound is horrible. Part of the problem is that the sub-woofer doesn't have a separate control and sometimes overwhelms the sound as you turn the bass up. My expectations for the stereo were very high when I purchased the car so of course it's very dissappointing to me. But, aside from the sub-woofer, the components are actually well matched which makes the most out of the mediocre components.

    Well, it only took about a day for the rattling to come back in full force. In other words, what the service shop did was a waste of effort. I will now bring it in tomorrow for service #2 (which I'm sure will be the second of many). And I will keep bringing it back until either they get it right or I can force GM to buy the vehicle back. Since I'm not happy with this car in the first place, I wouldn't mind the latter.
  • My G6 was in for rattle repair on the 8th of January and I got it back on the 10th of January. I live in a pretty rural area and the service manager had yet to deal with this issue. I brought several pages of these posts with me for him to review. So far, 99.5% of the rattle is gone. Mine was primarily coming from the back area above the glass. Occasionally, I will get a slight rattle/vibration from the drivers side windshield/ roof latch area. But other than that, I am pretty pleased up to this point. It was -1 during my morning commute today and not a sound from the top!

    Here is what the service order says: Customer states rattle noise from convt top while driving. Test drove, heard rattle, inspected vehicle, reviewed customer information from internet, looks like other dealers having trouble fixing rattles, some noise may be inherent to design. Reviewed bulletin and lowered headliner, needs new bumpers and grommets to start with. Removed rear glass trim, installed new bumpers and adjusted, installed new rubber sleeves and adjusted pin receiver, adjusted panel latch. Reassembled headliner.

    I will update if the rattle returns. Oh, and I do have the same heater issue that someone else mentioned where air comes from the windshield defroster even when the panel is set to floor or floor/dash. I just noticed that this morning. Good luck to all. Chrissy
  • Here is your solution if you top rattles over bumpy roads
    TSB#06-08-59-003B
    Part#'s 25898407 and 15815546 they need to order 2 of each.
    These are two new rubber sleeves that install on the two pins located on the rear top half. They mate with two reciever block that will need to be adjusted to the rearward most position.

    We love our G6. The top rattle has been the only major problem we have had. see below for symptoms and solutions for this TSB.

    Also if you hear a creak it may be coming from the two rubber seals in the doo jam rubbing. apply some Dielectric grease and it stops.

    Service bulletin "Rattle/Creak Noise Retractable Hard Top (Convertible) (Adjust Roof) #06-08-59-003B - (07/30/2007). Models 2006-2007 Pontiac G6 Built Prior to June 1, 2007. The conditions identified in the document were
    Rattle/ticking type noises over bumps in colder weather from mid-roof area; Rattle/ticking type noise over bumps from the front top of the windshield header area;
    Creak/pop type noise over bumps from rear quarter panel area;
    Seal itch type noise;
    Snap/ticking type noise over bumps from rear quarter glass area;
    Snap/knocking type noise over bumps from rear shelf/tonneau panel/flipper door area;
    Creak/pop/thump type noise over bumps in rear wheel well area;
    Creak/pop/thump type noises over bumps in rear trunk area.

    I would print this off and bring it with you - I find my vert's clunking roof sound is worse when really cold out. Planning on bringing it in next cold snap - when warmer the noise is greatly reduced.
  • My G6 HTC has the stabilitrac ooption. Whenever the temperature is 20 degrees or below, the "stabilitrac not ready" light comes on when I start the car and stays on for about 5 minutes. Has anyone else seen this problem?
  • I have the exact same problem. Mine isn't quite as predictable as 'every' time it's under 20 deg out, but I've probably had it act-up about 4 or 5 times this winter on cold days. (I live in Saginaw, MI, so we've been under 20 deg almost every morning for quite some time.) Let me know if you happen to find a fix.

    I'll be taking my car in for a laundry list of issues in early March, I'll also ask them to look at it then. My plans for repairs in March:
    - broken plastic latches on back of driver seat & side airbag
    - mis-fit of plastic panelling on wall leading up to passenger seat-belt
    - no-power from the lighter (looks like a piece might have been missed in assembly)
    - dent in back rear corner panel (got hit by some a-hole in the parking lot who never left a note :( )
    - get a replacement key FOB (original had a bad solder on the battery casing & stopped working
    - maybe try to get them to work on noise from the top if it's acting up at the time
  • Purchased a 2008 G6 Convertible last Sat. Sports, Premium, and Chrome Package with the White Diamond Tricoat.

    First of all this car looks amazing in the sun especially with that paint job, I can't wait till March or April when I'm able to drop the top.

    I previously had a Mini Cooper Convertible, and this car is actually more fun to drive so far, more responsive and faster.

    I'm sorta mad they didn't put an auto dimming mirror or Xenon lights on this car, that pretty much would have made my day. Also wish the gas mileage was a little better 15/22 sorta sucks but I work a mile from my place so its not to bad.

    I do have a few concerns/issues if anyone has the answer.

    1. Does the 6 Disc CD changer not play Mp3 CDs? Even my old sunfire did this.
    2. Is there a way to stop the AC from coming on everytime I turn on my car when its set to Auto?
    3. There a few scuff/scratch marks in the interior plastic, any way to do anything about that?
    4. Looking in the rearview mirror through the back window has a glossy/blurry look.
  • Congrats on the new car! To your points:

    wish the gas mileage was a little better 15/22
    - I've cleared 10K miles on my car and have found my mileage improved to about 18/24. Fortunately I'm not far from work either, it took me over a year to hit 10K miles.

    1. Does the 6 Disc CD changer not play Mp3 CDs? Even my old sunfire did this.
    - It won't play MP3s unless you burn them as regular audio tracks. This issue inspired me to get the XM subscription.

    2. Is there a way to stop the AC from coming on everytime I turn on my car when its set to Auto?
    - If the interior humidity is high, AC automatically turns on to keep your windows from fogging... it's a good thing that it turns on if you want to see out the windows, so I'm not sure why you'd want to deactivate it.

    3. There a few scuff/scratch marks in the interior plastic, any way to do anything about that?
    :confuse:

    4. Looking in the rearview mirror through the back window has a glossy/blurry look.
    - Mine looks fine...
  • I DO HAVE THE 3.9 ENGINE. I GET AROUND 24 25 MILES TO GALLON. IN SHOP NOW WITH THE BULLETIN'S POSTED HERE FOR RATTLES IN CONVERTIBLE TOP AND PAINT. I HAVE THE BLACK AND IT SEEMS THAT GM REGIONAL REP HAS FOUND THAT SOMETHING HAS HAPPENED TO THE CAR BEFORE I TOOK OWNERSHIP. CUSTOMER CARE IS VERY HELPFUL AND IS INVESTIGATING THIS PROBLEM. HOPE DEALERSHIP DID NOT DAMAGE CAR BEFORE I TOOK OWNERSHIP I BOUGHT IT AS A NEW CAR NOT USED.
  • 1) I don't mind the CD player can't play Mp3 files, especially since I can just plug in my Ipod, I was just wondering, you'd think that would be standard today on an upgraded sound system. By the way love XM ever since I got my first sunfire with it I'd been hooked ever since.

    2) Only reason I don't need the AC on is because when its 30 degrees outside and the AC goes on, it actually makes the heat blowing out of the vents colder, and besides you get worse gas mileage with it turned on. :)

    3) The interior plastic is very cheap seems to scuff or scratch easily, was just looking for a way to touch it up if that happens.

    4) Looking out the back window is fine, it just seems to be when I look out the rear view mirror through the back window, almost like a glossy blurr.
