Pontiac G6 Hardtop Convertible



  • Hello "thlhbrit",
    I found that the wind swirling around from the back, in between the front seats, caused a draft on the driver and passenger's necks. I built my own deflector from aluminum tubing and ordinary window screening. (I'm an aircraft & sheetmetal mechanic by profession). It resembles a "rollbar". The results were absolutely amazing! No more drafts and the car is extremely quiet. I highly recommend a wind deflector.
    Pontiac charges $420, but perhaps you can locate one on Ebay for less.

    Happy Holidays,
  • I have a G6 pontiac convertible 06 the top is not go the cable is bad do you know is this a recall ?? my name is Max 775-200-6751
  • Max,

    I do not know of any recalls regarding the convertible top. Which cable are you speaking about? There is only 2 cables regarding the top, they drive what is called the flipper door. This closes out the hole the top leaves when it goes into the trunk. The topstack is hydraulically driven, and typically if the top is not moving, it is an electrical (switches, cable lead not plugged in) not a mechanical issue.

    Please describe the issue your having... Does the latch by the windshield actuate? If so, it is typically a switch issue in the receiver (2 switches on the driver side, pop the header trim and check the connectors and the switches) or what is called a hall sensor attached to the hydraulic cylinder that drives the latch at the windshield. This can be checked by popping off the headliner (be careful not to damage it as you remove)

    If the latch at the windshield actuates, is the pump trying to actuate the top (is the pump motor whining)?

    These are the type of questions that if you can answer we can probably get to the bottom of your issue.
  • I've been reading here for a while and decided to join up to tell you about my G6 convertible experience so far. Aside from the minor rattles that I was able to fix myself with some adjustments, my G6 had been a great car. My only minor gripes were the lack of a locking glovebox and center console and the absence of an AUX port for my iPod. The top has been flawless so far and I also get a lot of looks in this car. Mine is a white 2007 GT with black cloth interior and I stripped the badging of the back end the same day I purchased it for a very clean look. People constantly stare as they roll by to get a look at the front because the drop tops are pretty rare and you dont see a lot of them in Chicago.

    I also modded the headlights with a row of bright white LED's across the bottom like the new Audi's have and I get other G6 owners offering to buy them from me. I can honestly say this is the must fun car I have ever owned and I dont understand the complaints about the Monsoon system, I used to design and install custom car audio systems and I have never heard a better sounding stock stereo on any other car. Be sure to keep the treble and bass at center level and raise the mid level to about halfway, it sounds great with almost any music.

    I solved the iPod problem with a factory direct interface that lets you control it from the radio and also puts up song info on the DIC, and it also lets you navigate the menus right from the 6 buttons used for disc selection and FM presets. It works with or without the optional XM tuner from the dealer.

    I only had one concern about a week ago on a bitter cold day, the passenger window would not roll back up under the seal after closing for a couple hours and then the problem fixed itself later that night. I cant say enough about how much I enjoy this car and it's minor issues are well worth the purchase, at least for me. I have kept the body and interior flawless and it still looks like it just rolled out of the dealership.

    I realize the top is very complicated and some of you have horror stories about the hard top but I came to find out my car was built and assembled on a Wednesday, they say the ones finished on Friday have the most problems on any vehicle assembly line, I wonder if this is actually true?

    Anyways, I just wanted to spread some good word about this car as I think it it one of the most unique that GM has produced in a long time and I absolutely look for any excuse to go driving in it.....

    Hey bro, glad you joined. I too am very happy with ours. In fact, after taking it on a round trip from New Mexico to South Florida (Keys) and back, we are really thinking about a new Mustang Convertible and not driving this one as much to "save" it. We have about 30K on it now and it is a 2007 as well.

    Anyway, glad you are happy with it! :)
  • I was reading some of the back seat comments above, I dont know why that guy is griping even after has has supposedly sold his G6. My kids have no problem with the room back there and when the top is down and the windows are up, it is very calm compared to other drop tops I have driven.

    And speaking of Solstice..... the top is manual......and they all get that strange bunching of material in the same place where the cloth top has those severe creases they designed in near the rear window. That alone turned me off to both the Sky and the Soltice. Brand new and the tops get all wavy in that same area, every one I have ever seen....

    I'm sure they are fun to drive but having a top that looks worn & stretched before driving it off the lot is very poor workmanship in my opinion.

    Sorry, but I love my G6........ I was reading more about the hard tops last night, GM rejected the first ones because they failed to go past 10,000 up and down cycles without a problem, so they re-worked some of the parts and finally surpassed the 12,000 mark, so GM signed off on them and let them bring the modules to Lake Orion, MI for assembly to be mated with a bunch of first run G6's for real world testing. It seems like the people who had problems were right out of the gate, I saw a few people who had thier G6 for only a couple days and the tops failed. I think once you get past 20-30 cycles with no issues, you seem to be OK, unless you get a hydraulic hose leak or something physical that causes the top to fail.
  • Hello Hollywood,
    It's nice to see another owner who enjoys his G6. As an aircraft mechanic for more years than I wish to admit to, I have been called a "negative person" because I always point out the flaws in an aircraft's design to owners and potential buyers. The reasons should be, reliability, & cost to operate or maintain.
    Many of the people posting on this site have legitimate complaints about their cars. However, all of us are talking about the G6 convertible. So my basic question is.....What did you really expect???
    You can include me in the list of people who would have made many changes in the design of the G6, but none of us were asked to. Therefore, all of us bought our cars the way Pontiac built them.
    I consider myself fortunate enough not to need my G6 as a daily driver. So during the harsh winter we're having in N.J., I only drive the car about twice a month to keep the battery charged. Yes.... it rattles, and rides like a truck, but I'm sure other convertibles have their downsides too. The car was made for "top down" enjoyment, and as far as I'm concerned, the car is a pleasure to own. I truly look forward to the first opportunity to go "topless" again.
    As always, happy motoring to all of you!
  • We have been using our G6 convertible plenty in the snowy weather. With a healthy curb weight, front wheel drive, traction control and stability control it's great in the snow. On the roads this morning there were a few patches of chunky ice and slush and it rattled a bit but considering all the extra parts it's still really solid with the top up. And the heated seats are nice, too.
  • Hello everyone,
    After a long, cold, snowy winter here in New managed to reach temperatures just above 60 degrees yesterday. Perhaps a little cooler than ideal convertible weather, but who cares!!!!! I drove my 12 mile trip smiling all the way, and even saw a few other daring souls doing the same.
    So G6 owners, it looks like the beginning of another season to enjoy open air driving. Have fun!!!
  • bvdj84bvdj84 Posts: 1,724
    Yes, I don't blame anyone for doing that. I have my G6 sunroof open sometimes in town if its over 35 or so. Feels good to have fresh air! Finally it is warming up, and I think the G6 has a summer appeal. It feels good to have the music on, the roof open.
    If I had the the convertible, I would so open it all up, you got heated seats for the would be awesome!

    I have a 2007, pontiac g-6, convertible, with 16,000 miles, just our of warranty, but have the gmpp, major guard,,, the dealer did not know what causes the whistle sound, I investigated on this web-site, bad baffle in muffler, now dealer will only cover half the cost of new exhaust system,,, (since muffler comes as whole unit, with exhaust system), I read on these sights, that dealers or g.m., are covering all costs, since this bad baffle-muffler noise problem is a defect from the start... how do I get my dealer to cover the cost of this g.m. defect???
  • gonogogonogo Posts: 879
    Actually the resonator is the problem. GMPP does not cover exhaust, it's right in there what is not covered section.
    Your lucky the dealer will cover half. Call GM and see if they will cover it on there customer satisfaction program.
  • Hello,
    I'm certainly no expert about that whistling sound, but I will relay a story about a dealership encounter I had. Last year, when I had my 07 G6 HTC in the shop for a defective battery, I got to talk with a tech who apparently knew his stuff. I asked him about the "weak spots" that plague G6's. My conversation dealt with exhaust noises too. I have the 3.9 engine and the exhaust seems a bit loud (in a sporty sort of way). He said that was normal and the only exhaust complaints dealt with the whistling sound. He said that he had replaced several exhaust systems, but since the replacement part was the same, the noise had a habit of returning after a while. I believe the noise comes from a drain hole, which is a common design in many exhaust systems. I wonder what would happen if that hole was just plugged up??? I know that if it ever happens to my car, I'll be experimenting with whatever it takes to silence it. Please let me know how you make out with your repair.Thank you. Steve

    You know I love my G6 HTC too! It had a few issues in the beginning and I posted them but it has been a joy is the 2007 model. I be interested to hear more about the modification to the radio for the iPod. Please let me know more. Thanks for sharing!
  • I’m not a ‘regular’ on this forum, but since my 07 G6 GT just rolled past 75k miles, I figured I’d give a short owners report.

    I commute 100 miles a day and find it to be a decent highway car with the top up. Less noise and rattles than my 03 Corolla. Doing the speed limit I consistently get a tad over 30 mpg. Wear and tear on paint, upholstery and controls has been as good or better than my other 4 vehicles.

    Top down driving is a blast. Very pleased with the low level of wind and noise. Steep rake of the windshield makes you feel a little more cocooned. Frankly, I like the little bit of shake and rattle. A convertible should be more visceral, I don’t want it to be just a big sunroof.

    My favorite feature is the adjustable pedals. I don’t know why they are not standard on every car. Every driver in my family from 5’ 2” to 6’ 3” has complemented the ability to find an enjoyable seating position. The front seats seem an oddity, though. People seem to either think they are the best or worst they have ever sat in.

    I’ve hauled adults in the back seats for hours. No one has ever complained about the comfort (and I almost always ask) but they do have a hard time getting in and out of the seat with the top up. It’s just annoying with the top down. Except my teens like to jump over the side.

    I really don’t understand the complaints about the trunk space. In all my miles, I have never had a time where I have needed to haul more than the trunk can hold with the top up. And I have completed several cross-country two person vacations with the top down and placing some items in the back seat.

    The exhaust was replaced twice for the whistling noise. First under warranty at 25k, the second at 55k for customer satisfaction at the dealer where I bought it. No recurrence, but should it happen again, I’ll just replace it with a non-pontiac exhaust.

    At 67k (mostly highway miles) I developed a vibration in the front and thought it might be a warped rotor. It turned out to be the original tires were delaminating, even though they still had good tread and appeared fine visually. Not the car’s fault, just a warning to others, if the front end starts vibrating, have them checked.

    I’d buy it all over again, but I could be convinced to trade it for a Camaro or Corvette….

    I wrote that my convertible whistles, and the selling dealer would pay half the cost for the new exhaust system,,, when I asked what half was, I never received an answer,,, it just happens that they lost their dealership, and are in arbitration. My wife told me to stop at the local Cadillac dearlership, where in the past; they preformed minor work on the G-6, while in warranty... I asked the young service writer, he just laughed, then I talked to the server manager. I told him the short version of my difficulties,,, he said "O.K.",,,
    I said "O.K." what,,, he said "O.K.", I'll cover it... There is a God.
    Thursday the Cadillac shop replaced the entire exhaust system at no charge...

    That is great news! Maybe GM is finally seeing what it takes to keep customers. I am happy for you! :)
  • bvdj84bvdj84 Posts: 1,724
    Do you know if they cover a rattling speaker. My rear left speaker is rattling. I am not one to play my music real loud either too. I am going to ask them about it when I am in next. Though, after a week of sitting, its not doing it anymore. hmm...

    I have been looking at new Pontiac G6 HTCs. I am able to buy one with the Sports Package and the Premium Package for $26,000 out the door, is this a good deal? What should I do? What would you do? I've really only looked at Pontiac's and no other HTCs, should I look at any other cars? Your advice would really be helpful. Thanks!
  • jpavlickjpavlick Posts: 12
    I would buy it... I bought mine in 06 right when they came out.... I now have 67,000 miles and it still looks new and still turns heads. For this type of car its a great deal.. I live near Chicago so it goes through some ruff winters.. I still love this car...
  • rjentrjent Posts: 19
    I would buy as well. That is at least 10K off retail. A phenomenal deal, and you might, since this is the last year of production, get them down even farther.

    As far as the car goes, I would buy another in a heart beat. We have over 30K on it and have done a couple of coast to coast trips (one all the way to Miami from NM) and it is a absolute pleasure to travel in. Got as high as 29MPG on that trip.

    Go for it! :)
  • twosmgstwosmgs Posts: 11
    Due to the late-2009 $7K dealer rebate, by mid-January ’10 there were absolutely no new Pontiac or Saturn vehicles of any model remaining for sale in the Northeast, and only a handful could be found in the rest of the country. If you uncovered a new G6 convertible, especially a 2009.5 model, you are indeed very lucky. Forget the color, buy it now! At $26K, it’s a great deal. Except for a cold-weather roof rattle, which was quickly fixed my dealer, my 2008 G6 HTC has been trouble-free, and has exceeded all of my expectations, which as an engineer, are typically “impossibly high.”

    hey guys just wanna say this is my first day on here and the site is very informing i must say there is a few people who tend to complain and do nothing but complain....but there is just as many that love there car so i will stick with car is perfect ,,....i do have a question i notice some rattles seems like from the back driver side when i do drive over rough pavement or bumps in the road some people i see hacve fixed there own problems is it something that can be fixed at home ?
  • twosmgstwosmgs Posts: 11
    On both doors, there's a spring-loaded pin which gives additional support to the latch, which will hopefully reduced flexing, and thereby keep the door in alignment. If this pin begins to stick, it has the potential to cause door/body rattles. Keep it lubricated with a thin coating of synthetic grease, such as "Super Lube," to enable free movement.

    If rattles still persist, take the vehicle to your dealer, since the roof's 2nd or 3rd panel mechanisms may require adjustment.
  • g6guyg6guy Posts: 10
    thanks.. i kinda think it could be the roof becasue i dont hear a thing when the top is down.. but once u go over some bumps in the road u here some rattle comming from the top at first i thought it was the drivers door or some people say the back quarter panel either way i still love my car just was wondering the dealer did say they would have to pull it all aprt to find the rattle to me its not wirth it its water proof and i want to keep it that but thanks for the info
  • steph418steph418 Posts: 1
    I had the same problem with the rattling - I took it back to the dealer 3 times and they have it for over 8 days total. FINALLY they actually called General Motors and found out it was the "bushings and grommets" that had to be replaced on the convertible top. Mine only made the rattle when it was cold - not driven first thing in the a.m. - before the sun would heat it up. After the first 2 trips to the dealer - I left it overnight and showed up first thing the next a.m. and told the Service Manager we were going to "take a ride" - he actually heard the noise that time - ha ha ha ha ha

    Hello Steph418,
    I am from GM Customer Service. So has the dealership fixed your vehicle or is it still at the dealership? Please let me know how the repairs go. Thank you,

    funny thing i happened to lift the cover on my spare tire of my 06 gtp convertable and noticed some water in the spare wheel .. the rest of the car was bone dry even when it rained out side.someone mentioned there could be a leak when it goes threw the car wash but i everything is bone dry very odd i cleaned up the wheel well and havent seen any water since anyone have the same problem
  • I've had water in the spare tire area on several cars over the years, and really never could figure out how it got there. On my G6 HTC, the spoiler nuts loosened twice, which could easily let water come in through the trunk. It's worth taking a look.
