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...

 

I just had my 2014 fixed for free but they scratched the bumper when they took it off.

 

they will send you a bill for that optional "work" they did for you

 

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.

Hmmm. might have to do this.
My old 2012 gimpala, I pulled the carped and sprayed inside fenders/wheel wells, etc with undercoating. not sure it helped much... and it stunk...lol


Dynamat-style mats prob way gooder

 

My 15' had water in the trunk when I bought it also. I discovered that this large grommet for wire was out of place and the smaller one below it was missing. I could pour water and see it coming in there.

 

kinda reminds me of those memes..."you had ONE job to do..."

 

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!

Good luck! Hope they do!

 

I had the same problem with my 2014. I drilled a 1/4 inch hole in the floor of the trunk near the spare tire. No more water in the trunk.

 

I guess if you are not under warranty and cannot afford the fix this is a reasonable solution but a hole could rust and when the water was coming into my trunk it was passing over a bunch of electrical connectors on it's way in.

 

Another Swimming Pool in the Trunk

This past weekend I happened to grab something out of the trunk and I noticed it was damp. Oddly enough, I had just seen the issue discussed on this forum, so with dread I popped the cover to the spare tire area and yes, water in the well.

Fortunately, I caught it before mold set in, but this is ridiculous. Seals failing on a non-moving part in such a short period of time is clearly a design/manufacturing defect. Addressing it for the 2014, but not the 2015 when the same seals are used is clearly evidence that GM does not give a damn.

Up until last week, I loved this car. Could not rave enough about how GM got it right - a beautiful, comfortable and reliable car. NEXT DAY, check engine light is on with a "minor emissions leak". WTH - does everything break at once and is this ride just getting started?

I was in the same mindset. We found a used ltz and my wife and I were both happy with it. Beautiful car. Haven't even owned it a year and now things are starting to fail and I'm wondering if we made the right call. Evidently these new cars are not engineered to make it to 100k miles. I'll keep driving the car it replaced that used to be my wife's daily driver. Toyota Camry with 225k miles and no major maintenance except oil changes, brakes, and batteries.

When you make a car to last you build a customer base, when you build a car cheap to be expendable you lose long time GM owners like myself.

 

My personal method of buying cars is to wait until many years after any major redeisgn - after it's been "refined" for many years.

For example, I didn't buy an 8th gen Impala until the 2012 MY (6 years after major redesign) - and I didn't buy a Dodge Challenger until the 2018 MY (10 years after major redesign). That is just the last two examples. I tend to do the same thing with engines - I tend to prefer "older" engines that have been around for a while and have a proven reliability record. Engines like the GM 3800, GM 3.6L and the Dodge 3.6L Pentastar.

I *did* buy a first model-year Buick LaCrosse - but that was only becuase it had the GM 3800 Series engine, which was a bulletproof engine. I did still suffer some other first-model-year issues with the car though - and was a good reminder not to do that again (although, overall it was still a very reliable car).

That being said, when you do this, you'll never have the "latest thing" - but you will have a reliable car.

 

My 2015 Impala has a water leak in the trunk which was just discovered. The water is coming in thru the taillight gasket the same as yours. I have been quoted $410 +tax to do the repair. I also paid $140 charge to find out where the leak was coming from. I bought the car new. You reported your leak on this forum in 2016 and my car would have been under warranty during this time. I'm not impressed.

 

Here is information on how to fix the problem, if you want to repair the seals: https://static.nhtsa.gov/odi/tsbs/2014/SB-10092869-0335.pdf

There are YouTube videos on how to replace the seals, and partially remove the rear bumper fascia (cover).

 

This is a very easy fix! Dont pay money for someone to do it! The seals are 10 dollars each!

 

Hence, Stealerships, lol!!!
