Pontiac G6- Water leak

2456710

Comments

  • My G6 has accumulated up to an inch of standing water on the floors of the back seat. The insulation under the seat was soaked as well. I was told it was a bad seal in the rear window but now I'll re-think it. Vent tube sounds easier to fix. I love the car otherwise but my wife won't even ride in it. I didn't get any kind of notice on it and trade in value is very low. I'll take the loss and trade it in.

    I would get out if you can! Before you get buried deep in the silly problems.

    Selling it would be worse than trading it, so trade it on a new car, I would stay away from a new pontiac! In fact, I would stay away from GM in general right now. Let them work their business out first. There are so many other cars that are not GM that would be so much fun! No car is perfect, but to have this going on, not acceptable!

    sunroof drain tubes are the culprit 90% of the time . the tubes are short in the front and have to much tension in the rears pulling the tube out of the outlet. gets them wet at the rear half glass area, seat belts , under the rear seat and carpets and eventually to the front .
  • I have a 2 dr 06 G6 and I've noticed that after it rains my seatbelts get wet in the retainer. I'm not sure if it is the sunroof leaking or the seals along my door. I pulled the molding and the floor in the rear is wet and molding on both sides. I also pulled the seal up from the floor along the door and water ran out of it. My warranty has just expired and I want to know what is wrong and if I really need to take it in. I would appreciate any help.
  • I have a 2008 G6 Sedan with no sunroof.

    I park in my garage at home every night. I park in a parking garage every day at work.

    It has NOT rained in a week and even if it had rained, I have no sun roof to leak.

    Two days ago I mopped up standing water on the back passenger side floor board. There is no evidence of water or moisture anywhere else in the car. All other floors are dry. All seats are dry. All doors and seat belts are dry.

    The water is obviously coming up from the floor, but how? And where? And why?

    Anyone?

    My problem was definitely the sunroof drain. My car was an 05 and it was covered under the warranty because the mileage was under 36,000 miles at the time so check it out, call the GMC 800 number and they should be able to direct you on where to call in your area. Good luck!

    The problem is coming from the air conditioner drain it is backing up into your car and flowing to the back passenger floor board. There is a plug in the drain you need to replace it with a rubber boot you can get at the dealership they know all about this problem. the part costs $7.00. The drain is located on the firewall behind the metal shield under the car.

    has to be a/c drainage problem
  • Yikes! We just had a ton of rain here in the Chicagoland area AND it's been very hot and humid. I just noticed tonight that I had a puddle of water on the floor in my back passenger side area. I thought maybe I left the window down a bit, but no evidence of that. Window was fully up. Thought maybe water bottle fell or something. Nope. No water bottle in sight. This A/C thing that others have posted has to be the problem. My car is almost at 50k miles now. A 2007 G6 sedan. Great. Guess I am screwed, unless I can find someone handy to fix it for me. Don't think I am buying a GM car next time. I think warranty or not, if a company builds something faulty, they should repair it. It's a problem and they need to fix it! Ugh!?

    Your description is the same as mine. I have a 2008 g6. Took it to a garage, problem was noted as being a leak coming off the A/C evaporator. Not totally convinced yet problem is totally fixed. But i just ripped the carpet out of the passenger side of the car. Totally soaked FWD to AFT. I'm gonna keep an eye on it this week to see if what they did fixed the problem.
  • So did anyone take their car in and figure out the issue? We lifted the backseat up and the padding is soaking wet underneath the seat? What the ????? Who built this car??? Why would they put water drain tubes towards the backseats? Luckily I have no kids - yet or anyone to ride in the backseat anyways but it's starting to smell back there. So for now, I am riding around with a shoebox prompt up my backseat. Yeah...real ghetto style like! Gggrrr.... I am hesitant to take it to dealer cuz its not under warranty anymore. I almost have 50,000 miles on it now. Should I take a hair dryer to it? It doesn't seem to be drying. My dealership told me there is no recall notice out on my car. Did some redneck GM employees put my car together and route the drainage pipes to the backseat as a joke!? I mean seriously!! Guess I can save myself a bath in the mornings...I can just bathe in my car on the way to work!
  • I just had this same problem happen to me on my 2008 g6. The only reason I knew something was wrong was because my windows kept fogging up. I had my car into GM several times before my warranty expired and they said nothing was wrong (in fact, they told me that it was because my hair was wet) My car just hit 52,000 miles on it and is no longer under warrenty. I took the car in one last time and the figured out that the ac was draining back into the car. They tried to charge me $120 to partially dry the foam and carpet and seal the leak. I had to drive around for 3 days with my carpet up and airing out. Plus my car really stunk like mold. I let GM have it and they ended up not charging me for the repair. My advice is to call the GM Corp. office and file a complaint. They will listen!
  • Hey, I have a 2005 and rain poured through the light by the rear view mirror then all was calm for a couple years later then last year we noticed the rear floor soaking wet. I had no idea what was going on until I found this site. I'll have to follow up with corporate, I agree they should have a recall after reading these posts! We've had the back carpet cleaned but it still smells and we do have a child. We're concerned about mold under the carpet on the padding. We're not sure how to pull the carpet up in the back seat, any tips? Thank you.

    Mine is also a 2005 G6 and I have read 100's of postings regarding the leaking sunroof or moonroof but yours is the only one I've read that sounds identical to how mine is leaking. Mine also poured down from the light by the rear view mirror. I have pulled the head liner down and by the time I got that far, I could see the drain tubes but are in a very tight area, I couldn't tell whether or not they were disconnected as I ran out of daylight, so I put it back together. The last rain, we vacuumed 8 gallons of water from the back passenger floor board. Seatbelts and seats were also damp. The moldy smell and the stained seats are terrible.I took mine to Classic Chevrolet in Arlington, TX and they kept it overnight claiming they ran water over the car and it never leaked. Famous saying from these idiots, if it doesn't do it while we have it, we don't know where the problem is. I'm curious if you have been able to fix yours since it seems to be identical to my leak and if so, what did you end up doing?

    About 1yr & 1/2 after I got the car (purchased brand new) it was raining and when I braked water came pouring in through the light by the rear view mirror, sunroof button and also along the passenger side down the front windshield inside the car - took the car in to have it checked and they said the drains from the sunroof were clogged. Then was fine for a couple years. Now, its not only leaking through the light again and down the windshield - my passenger backseat floor is soaked AND the front passenger floor - i don't know where the leak comes from in the back seat but in the front passenger - I can see it pour in from under the glove box near the passenger door - I have checked the door itself and its not coming in through the door and the seals but from under the glove box. So not sure what the problem is - and the car isn't under warranty (but when the drains were fixed the first time that wasn't covered by warranty which wasnt cheap.) - Obviously, this is a defect with the car - so why is this not a recall problem? And it should be fixed for free, cause since this has been "fixed" once before, it will probably cost even more this time around. - frustrating!

    danine35,

    I apologize for the problems you are experiencing with your vehicle. The first time you had the vehicle fixed, was it fixed at a GM dealership?

    Thank you,

    Caron,
    Yes, it was - took it where it was bought the first time (pontiac dealership...and since pontiac is no longer, its now a Kia dealership)

    I would encourage you to take the vehicle in to a GM dealership. Please keep me posted.
