Pontiac G6- Water leak

I have an 05 Pontiac 4dr G6 GT Everytime it rains rain seems to leak onto the drivers side floor. It is coming from the side panel under the dash and I cannot seem to find the original source, it has become very frustrating. Anyone had a similar problem?

  • I have the same year, and GT model. I just bought it and discovered the problem as well. I can't figure it out. I plan on taking it in to see if the dealership can figure it out, if I find out first or if you or someone else can figure out how that water is coming in from under the dash first please let me know. Thanks!!!
  • I also have an 05 Pontiac 4dr G6 sedan and it leaks on passenger side and goes into back floorboard on passenger side..... Dealer replaced drain hose in sunroof and says this will fix problem.... I they are correct ...... The headliner and passenger seat showed no signs of leaking.... was still in warranty by 200 miles..... I Hope the dealer repair guys know what they are doing ...... dale_littrell@yahoo.com

    i had the same problem out of my 2006 GTP there is a factory notice that went out to all dealerships it was a problem that was fixed in 07 the drain lines are too short they have to replace them with longer lines this repair will cost you nothing it is just like a recall take it to your local dealer and have it fixed
  • I had similar leak on drivers side about 2 weeks ago. Water got into computer electronics and car barely would run. Also drivers side floor was soaked. Had it towed to dealer. They said it was water coming from the sun roof coming down the channel into a damaged grommet on the door light switch. Car is under extended warranty and yet they still charged me $290! Said its not covered. I've lodged a complaint with the dealer and waiting for a response. I see this is an on-going problem.

    Sounds like you got screwed.....
  • Water leaks from headliner (dearler haven't fixed the problem yet) Out of warranty I ahev to pay for that as well as rental car.

    Purchased car 4mths ago, problems noticed within the first 30 days...

    Well, you would think the dealer would know about the issue, considering the car was on the lot, and more than likely it rained. So, perhaps their hiding something. ??

    what year G 6 ?
    it is a very common problem. leaks down the panels on the rear side windows, or water in the headliner. what area are you?
  • ralkaralka Posts: 72
    do you want to fix it yourself ?
  • Yes...I still have an extended warranty but, I can not afford to pay for a rental car knowing that they will hold my car longer than needed as well as they can not seem to fix this problem...The Service center told the dealer to put me in another car...Because they can not fix the problem.....

    are you still having leak problems?
  • I have been reading your posts are the drain hose avaibile to be purchased? My car is out of warranty by time not milage.

    you don't need to replace the rear tubes they can be moved to accommodate
    they only need to be replaced if there is a physical problem with them, bent broken etc...

    My 06 coupe leaked more than once. The first time dealer said hose(sunroof drain) was loose. Second time it started leaking again the same time I got the repair campaign letter. It just started leaking again at 44,000 miles. I have the GMPP but the claim was denied because water leaks aren't covered. I was able to argue that the repair under the campaign must have been faulty and the service writer at my dealer got the repair covered. It was aggravating and I know if it leaks again they won't cover it.

    g m is tough to deal with after warranty. and the dealer doesn't want to eat the repairs. Especially with all the financial issues right now.

    I actually took my car to the dealership and it was one of the drains from the moonroof , when I took it in the mileage was under 36000 miles and was covered under warranty. Good luck!
  • 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.
