Just wondering has anyone had any issues with the 2016 chevy malibu lt having moisture or water building up in the trunk? Even on the sunnies days I still find moisture within the trunk of the car. I've ran water over the whole back half of the car and can't figure out where the water is coming in from.

Hello @Eddie8716. I see you wrote Chevrolet Malibu LT in your description. Before offering suggestions I want to make sure this is a Chevrolet Malibu LT and not a Chevrolet Malibu Limited. Does your car look like #1 or #2 below?

 

[Eddie8716]

This would it. I'm really trying to figure this out. So I don't have a mold issue soon.

Also it only the right side of the trunk liner that gets wet when it rains

Thank you for the pic! That would be the 2016 Malibu Limited.

On gen8 cars targets include the weatherstrip around the trunk, seal around rear lights, and rear window seal. When you run water over the rear end no water gets in? Or does water still get in you just can't figure out where?

I had water coming into my trunk via the pressure valves in the bottom of the rear quarter panels, behind the trunk lining. Would find water in the spare tire wheel well. There is a tsb or information from GM about it, which lists all of the possible reasons campb292 mentions, plus the wire grommets and the pressure valves. I believe I found it on this forum, but googling it would likely also locate a copy if you wanted to read it. Was pretty thin of content regarding how to fix—just showed what the problems may be.

Specifically regarding the valves, they may have been installed poorly, leaving a gap for water to leak through. I sealed mine with some silicone but I think the problem may be with the valve flappers themselves. When the car is moving, those valves would be open so air getting into the cab has a way out the trunk. One would think the air exiting would be of enough force to keep water from entering but I still think water may be flying up from the rear tires, right against the flappers. Bad design in my mind. If you pull out the entire liner, you will see the pressure valves. Even if you just remove the pins holding the liner at the rear of the car, you can move the liner enough to see them. Because you have water on the top of the liner itself, I would not suspect the valves in your case, or any wire grommets or other things under the liner, so the other options are more likely.

Good luck,
Mark

Yes I had that issue they to replace seals at the back of the window. It leaks from above and accumulated under the cover in the trunk . Loft up the floor thearea where a spare tire would go .

I am having the exact same problem on my 2013 Chevy Malibu only on the right side of truck. My liner and anything on that right side gets soaked. It’s now on my right tail light, I get in my car and have moisture on the inside of my windows. If this is a problem with so many Malibu’s there really should be a recall !

Please know that we sympathize with you, since we are owners, too.

But also please realize that a "recall" is for items related to safety, not inconveniences. Your car is now 10 years old, so unless there is a special program (not a recall) for that particular issue, it's on you to fix it.

If you search around CMF, you may even find where someone has done just that, and then you could benefit from their generosity, which is the biggest reason this forum is here and why so many of us joined it and remain members.
