WeatherTech Floor Mats - WT42378

  • Cargo Area
  • Gray
  • Custom Fit
  • Thermoplastic
  • WeatherTech
  • Contoured

Protect the interior of your trunk or cargo area with this weatherproof, impact-resistant liner. Advanced surfacing helps trap fluid and debris; textured surface holds mat securely in place; and custom design ensures a perfect fit for your vehicle.


Features:

  • Custom molding allows for complete coverage of your trunk or cargo area
  • Advanced surfacing provides channels to trap fluids and debris for easy cleanup
  • Raised side lip keeps spills contained
  • Unique material is formulated for durability
  • Textured surface securely grips the floor and holds your cargo in place during transit
  • Gray finish complements many interiors
  • Made in the USA


Your vehicle not only gets you from point "A" to point "B"; it also allows you to transport people and pets or to haul luggage, lumber, outdoor gear, groceries, plants and more. And all this activity deposits dirt and grime, damaging your interior. Protect it with a WeatherTech Cargo Liner. Digitally designed to fit every contour of your trunk area, this custom liner is constructed of TPO - a weatherproof, impact-resistant material made to last. The cargo mat features a textured finish that helps to prevent items from shifting during travel. And the raised lip and channels provide barriers to stop liquids from spilling onto the carpet, making it easier to clean up messes.

Just installed it fits well it was kinda rolled up so it still isn't laying flat but I'm sure it'll get sorted out

When I received the mat, I warmed it in the sun to soften it and dropped it into place for a perfect fit in the kinda quirky space of a Bolt EV. It's especially handy on a nursery run when we come back with dripping wet plants with soil attached. Just pop it out, dump out the water, soil, etc and pop it back in. After a year of faithful service, we highly recommend this product.

2013 Toyota Sienna
The WeatherTech liner fits well in the back of our new Toyota Sienna and provides the protection we wanted for the interior when we travel. We normally stow the third row seats since it's just the wife, dog, and I travelling so the mat protects the stowed seats/carpet from the soiling and wear/tear of our luggage, gear, etc.
We are extremely pleased with both the product and the great service.

Still very pleased with them...especially the cargo area mat since we have many long distance trips with our Sienna van and the mat has been perfect for protected our gear and the van interior.

I purchased the WeatherTech mats for the front and for the cargo area of my '17 Chevy Bolt. The front floor mats fit perfectly once they were warmed up in the house to make them more flexible. To me, WeatherTechs are more plastic-like than rubber-like but they do the job. I had issues with the cargo mat. Be aware that there are different mats for the "false floor" and the floor in the cargo well for the Bolt and this wasn't clear at the time of my purchase. Make sure you know which mat you want to save return and repurchase.

Thanks for the follow up Jim. The # WT401046 is designed to work for your 2017 Bolt with the false floor. The information is listed as a Tech Tip on our fit guide page. I have provided links for your reference.

Works real good another Weather tech product you can count on

I very much like etrailer (vendor) but this particular product (weather tech cargo liner) does not meet my full expectations. It fits nicely in vehicle when 3rd row seating is folded down but when 3rd row seating is up you have to remove the weather tech cargo liner. The OEM version from KIA has a fold such that when the 3rd row seating is raised, the cargo liner simply folds back on itself (and fits nicely regardless if the 3rd row is up or down).

This is a great quality product. It fits my 2014 Highlander Limited perfectly. Also, I was very pleased with etrailer.com shipping my cargo liner right away. I selected regular ground shipping, and the product came pretty quick. Thank you!

Perfect fit for the 2025 Lexus GX 550 6 seater model, given Lexus does not make a large cargo mat/liner. Just let it sit out in the sun for 5 mins and it will unfurl and be ready tor installation.

It does not fit. When I called to complain I was told to just cut the corner off and then it would fit. Your ads say they are laser measured to fit perfectly, the cargo liner does not fit!

Hey, Larry. I looked into this and you are right! This liner should be a perfect fit and you shouldnt have to cut it. It looks like there are two different kinds of liners for 2025 Hyundai Tucsons with and without the Bose sound system. The one we carry is for Tucsons without the sound system which is why its not a perfect fit for you. At this time we dont carry the other liner that would fit, but Weather Tech does have it on their site. Let me know if youd like to go forward with a return and I can help you with that :)

Exact fitment. Quick shipping from etrailer. Made for my car. Looks like a factory accessory. I would recommend both the Weathertech custom floor mats and etrailer for the positive shopping experience I had.
by:
2014 Mitsubishi Lancer
This cargo liner is fantastic!

The fit is precise and matches the trunk of my car exactly. It is slightly thinner than I was expecting, but the liner is very light yet stiffer than regular floor mats. The light and fairly flexible material makes for quick add/remove easing cleanup. Edges around the entire perimeter are over 1" tall and will hold a significant amount of water/dirt/whatever without destroying the trunk.
by:
The lip around the edge doesn’t really hold its shape to well to contain liquids, and the bottom has no spikes or traction, so the whole thing slides on the carpet. It slowly slides toward the door, and then the door doesn’t close. Good material I guess, but really poor design. Ill buy a different one as soon as I catch my breath after paying WeatherTech prices for something that doesn’t do the job.

  • Gray Weathertech Floor Mat Recommendation for 2015 Honda Pilot
    There was a big enough generation change between a 2015 and 2018 Honda Pilot that Weathertech had to create new fits for the vehicle. So for your 2015 Pilot the Weathertech cargo mat part # WT42378 is a confirmed fit and then for matching front mats the part # WT461741.

    The WeatherTech Cargo Liner # WT42378 will roll up when you want to use additional third row seating with your 2015 Honda Pilot. These liners are a custom fit for your vehicle and also come in black # WT40378 and tan # WT41378.

  • Cargo Liner Function With 3rd Row Seat On 2010 Honda Pilot
    For the 3rd row use in your 2010 Honda Pilot, I reached out to my contact at Husky Liners and the WeatherBeater Custom Cargo Liner # HL24361 is too rigid for use with the 3rd row, the cargo liner would need to be removed. I also reached out to WeatherTech and the WeatherTech Cargo Liner - Black # WT40378 will allow you to roll it up when you use the 3rd row seat and it comes shipped rolled up in this way, however, they don't recommend you keep it rolled up for long periods of time (2-3...
