Hello All, I just purchased a used 2015 LTZ from a Chevy dealer. The car is in great shape and is in "like new condition". When I was purchasing the car I noticed that there was water in the spare tire well. I pointed this out to the dealer and he assured be that he would get it resolved. I left the car at the dealership a couple of days in order for the leak to be fixed and so it could be detailed and serviced (the car was just turned in on lease). I picked the car up and they told me that the leak had been found and resolved. They told me that the seal on the rear windshield had to be redone. I took the car home and have had it a almost two weeks. This weekend I was installing some sound deading mat in the trunk area hoping to reduce some of the rear road noise when I noticed that the carpet was wet on the drivers side. After reading through several post I see where this was a issue on 2014 gen 9's but I haven't seen where any 2015's were affected. This car has only been in the rain once since I have took ownership and the rain was not severe. I took advise from previous threads and closed the trunk and ran water down the back of the windshield, it appears that the water is coming in through the taillight gasket and making its way into the trunk area. I am planning on taking the car back to the dealership and have good faith that they will get it resolved. I would think that this car would have the new style taillight gaskets installed from the factory? Has anyone else had any issues with a 2015 gen 9 leaking in trunk? I always feel better walking into a situation knowing what what others have experience at least I can ask them did they check...... Thanks

Sounds like a new Chevy. Hopefully the dealership will try and resolve the leaking issue.

No leakage on our 2015. Hope you get it fixed before it gets lots of mold in there.

My Mom's 2015 2-LTZ has a leak in the trunk too. I don't know where it's coming in but the taillights sounds plausible.

My 2014 Impala 2LTZ, purchased new, was repaired under the satisfaction campaign/new car warranty for the leaking taillight gaskets. GM issued new design taillight gaskets. The repair involves removing the rear bumper fascia and taillamps.

I suspect your only recourse is to return the car for warranty repair.

It amazes me that GM / Chevrolet can't build a new car without a taillight gasket that doesn't leak water into the car. It makes me wonder what other shortcuts were taken with the vehicle and its design. Classic poor quality.

Good luck.

Find a person on this forum called 1970cs.
He had quite an experience with water in the trunk...

just wondering about the sound matting that you put in the trunk.......did it help with road noise? Also, did you cover the entire trunk or partial. If you have a pic, that would be cool.


Thanks

I see that I have been paged!:yahoo:

Anyways I agree with the others that should have had the 3 revision tail lamp gaskets! Mine were put in summer of "14" after 2 1/2 weeks of tearing out everything, overnight mold growth, finally the GM engineers came with some sort of cocktail that finally killed the mold. They did cover a rental for the entire time.

Due to the time it takes to drop the rear bumper and valance, I would let the dealer do it under warranty. It could be mis-formed metal or a missing gasket???

We also have new style 2014 Silverado that the daughter was wondering why the back seat was wet (good catch for a 13 year old) found out that the CHMSL was leaking water into the cab! I ended up pulling the lamp and cleaned the area up and used some household acrylic latex caulk on the gasket area and it has not showed any signs of leaking for the past 100 days.

My 2003 Nissan Altima had that same issue. My 2010 Malibu and 2015 Impala don't. Usually they need to replace the gasket on the trunk and also check that there are no holes in the trunk itself. My Chevy Dealer has been great about anything under warranty

Thanks, yes I read about your trouble in the past post. I have no signs of mold and the carpet was damp after the rain not completely saturated. When I closed the trunk and ran the hose down the roof to the trunk for a few minutes and opened the trunk then I saw water standing in the spare tire well again. I did not use a lot of pressure with the hose and tried to simulate a heavy rain with the water. It was only wet on the drivers side under the tail light and looked liked it ran into the tire well from there. Everything else was dry, I had all the carpet out while testing so I could dry it out before and after. It does not sound as it is as bad as yours but thanks to this site and and people like you posting I could find out what to look for. I keep in in a garage and don't drive it much during the week (I drive a company car) there is no telling how long it would have gone until I had noticed it had not been fixed! It could have turned into a huge mold issue like you had. I am planning on getting it back to the dealer and pressing them on repairing now that I see where the problem is. I'm glade there are resources like this forum that we can turn to when problems arrise.

I hope the pictures show up... Yes I do think the mat helped with the road noise a good bit. I noticed in my car that the all four doors were very quiet and most of the road noise that I heard was coming from the trunk area. After I looked under the carpet I saw very little insulation between the carpet areas and the metal (I could have been missing some I purchased my car used but I asked a friend that had a 2014 and he reported the same as I had). I had never installed any of the mat before and read up on it and decided to buy the Noico Black 80 Mil Brand in black finish it had great reviews and was priced less than the others. I was not not looking for anything for a sound system or to stop rattles just to cut down on noise and to install under carpet and this brand had good reviews for that purpose. I removed all of the carpet from the trunk area and made sure that all the metal surfaces that I installed it to were clean and wiped down with de-greaser. Being that the car was almost new this was not a hard task everything was basically clean. I started with the bare metal behind the wheel wheels and installed there first then covered the wheel wheels. I removed the spare tire and covered the entire well. I then removed the styrofoam "storage Box" and installed it underneath it. I removed the plastic trim piece that is clipped on the rear above the Buber and installed the mat on about 80% of that. I tip that I read before installing that helped me out was to take paper patterns of areas first before then test fit before applying. Once the mat is down it is down, sticks like crazy. I also found that it was easier to do areas in 4 to 5 inch strips overlapping each one about 1/8". I purchased the mat roller and do not think that I could have completed the job without it. You basically apply the mat, it has raised squares on the top side, you roll the squares flat and shape the mat into all the contours and move on to the next piece. I live in SC so the temp was in the hi 70's so I'm sure that helped it form into contours better, the instructions indicated that a heat gun or hair dryer could be used if needed. I would have made a mess If I had used one. Is the road noise completely gone, no. I can tell at hi way speeds that it has helped. It cost me about 60.00 for the whole install and about 4 or 5 hours of my time. I asked my dealer before I installed the mat if it would effect my warranty in anyway before I installed the mat and he told me it would not. I was very careful not to install the mat on any welded seams and made sure that I cut holes around all fasteners so that the mat would not come into contact with them. I glad I did it, if not...I probably would not have seen that my trunk was leaking.:idea:

If memory serves mine was leaking pretty bad! My car wash towels were actually freezing from water that was wicking from the carpet. All carpet, rear seats and rear package tray were replaced under warranty.

Did you have a smell? Because I had a leak thru the taillight which the dealer fixed but they couldn't get the smell out. Any ideas

I'm a car retailer for a car dealership and our strongest odor eliminator is Ardex Vehicle Hygienist which I don't think is available retail but it's essentially a chlorine dioxide bomb. Mix it up, set it in the area, close it up and let it sit for a couple hours. I also suggest letting it air out open for another couple hours and let the chlorine smell dissipate a little. Once the chlorine smell fully dissipates, the smell will be gone.
When Ardex sold us the 1st bomb, he guaranteed the smell would come out or he would come clean it himself.

If you don't want the chlorine smell then baking soda is usually a good option but I can't guarantee it will eliminate the smell.

2015 chevy Impala LTZ trunk leak

I too have this make ans model which was also a returned lease with low miles and nearly new condition. I noticed a weird odor. Upon investigation I found almost 5 inches of water standing in the wheel well. My entire carpets were soaked. We took it to our Chevy dealer because of course I have a 6 yr bumper to bumper extended warranty. They claimed no knowledge of this problem in 2015. Of course the warranty does not cover leaks? WTF?? So they spent 3 hrs tore the entire back end apart, sealed some screw holes and rescrewed them. Well yesterday I looked because i never pt the carpet back and theres 2-3 more inches of water. I will go back as this is a defect and they will fix it under warranty as it appears to be a manufacturing issue. Glad I found your post!
