2018 Toyota Tacoma Body & structure Problems

The cab vents failed causing water to soak the carpet and pad from the back wall to the front of the cab. Mold was growing through out the the cab. Carpet & pad had to be removed. This is a known problem by dealerships and owners of Toyota Tacoma. Because the water was under the seats, trim and weather mats it went undetected exposing us to mold. Problem was reported to Toyota dealership and Toyota Corporation. A case was logged 07/10/2026 as Case # 260710001840. The resolution offered was ordering and replacing parts. All parts required for repair and on backorder. Hundreds of orders for these parts in their system. Carpet and under mat had been replaced 05/02/2025 due to a Toyota recall campaign 21TD03.

WHAT FAILED: The clear coat finish on the exterior paint of my 2018 Toyota Tacoma has failed (cracking) in two separate locations on the same vehicle, indicating a manufacturing defect rather than normal wear. In late 2024, I discovered clear coat cracking on the roof and hood. I reported this to Toyota (Toyota case #241028000714) and paid approximately $2,000 out of pocket to have an independent body shop repaint the affected panels, as Toyota corporate declined to assist after the repair had already been performed. The clear coat is now cracking again at approximately 48,925 miles, this time on the cab in the pillar/trim area between the tops of the doors and the roofline. The vehicle and affected areas are available for inspection upon request. SAFETY IMPACT: This is a cosmetic exterior paint/clear coat defect. I have not identified any impact on vehicle operation, structural integrity, or visibility, and I am not aware of any safety risk to myself or others resulting from this issue to date. I am reporting it to document a recurring defect pattern on this vehicle. REPRODUCED/CONFIRMED BY A DEALER OR SERVICE CENTER: The 2024 occurrence was inspected and repaired by an independent body shop (not a Toyota dealer). The current occurrence has been reported to Toyota corporate (Toyota Brand Engagement Center) along with photographs, but has not been physically inspected by a Toyota dealer. INSPECTED BY MANUFACTURER, POLICE, OR INSURANCE: Toyota corporate reviewed photographic evidence of the current issue through my correspondence with the Toyota Brand Engagement Center, which I have asked to be linked to prior case #241028000714. Toyota has not physically inspected the vehicle. This is not a crash-related issue, so no police or insurance inspection has occurred. WARNING LAMPS OR PRIOR SYMPTOMS: Not applicable. This is a cosmetic paint/clear coat defect rather than a mechanical or electronic system issue, so there were no dashboard warning lamps or system messages

The cabin pressure vents, located at the rear of the cab below the rear window on the body frame have failed. The seal on the exterior of the vents has dry rotted. This has caused an extensive amount of water intrusion that is undetectable until it has been present long enough to cause mildew issues. Being that water enters below the vehicle carpet and padding you cannot see it, your first warning sign is smell. When I began to assess the issue I pulled up my carpet to find standing water and mold. This is supposed to be a safe environment where I can transport myself and my family and I now I have to be concerned about mold inhalation each time my toddler sits in my truck. Toyota needs to do an immediate recall to the cabin vents and replace them with a product that can actually with stand the elements. Additionally they need to replace all the carpet, twill, and padding that has been compromised.

The contact owns a 2018 Toyota Tacoma. The contact stated that while the vehicle was parked, there was an abnormal odor coming from the inside of the vehicle. While the vehicle was being serviced, the dealer discovered that the inner padding on the front passenger side, the rear passenger side, and the rear driver side was soaked with water, and due to the water accumulation, there was mold forming on the floor. The contact had placed towels to soak up the water while driving; however, the contact later discovered that the mold had spread to the towels as well. No warning lights were illuminated. The dealer diagnosed the vehicle and stated that the rear cabin pressure bin needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 144,000.

The 3rd generation Tacomas rear cabin vents (2 vents) allow water to enter the cabin because they are not tight to the body or sealed properly. The water leaks down the back wall and forward onto the floor soaking the carpet and padding underneath. The water in the carpet/padding has yielded mildew/mold throughout (water goes all the way to the front of the truck). The water also leaks through a floor grommet into a section where the cab mount bolts are and significant rust develops. Not only is the exposure to mold a health hazard, but the corrosion/rust on the cab mount bolts is a significant structural concern. There are many online posts with this problem, and i have just recently found this on my Tacoma. My vehicle has had the 3rd brake light recall, and this issue is completely separate from that recall. Toyota has a history on these vehicles not sealing them as they should. 1. The 2 rear cabin vents fail to keep water from entering the cab. I am happy to provide the vehicle for inspection. 2. Exposure to toxic mold is a health concern. Significant structural damage to the cab mount bolts is a concern if the vehicle were to be in an accident. 3. Numerous people online have confirmed this issue, and they have indicated dealerships are well aware of the issue. I put a garden hose to the back of my truck myself and saw water entering the vehicle. 4. Vehicle has not been inspected by manufacturer, police, insurance, etc. 5. Unknown when water leak first started. In the past 2 years i have started to notice a mildew smell after a rainy day. I am happy to provide additional photos, but the internet is full of this very issue. Please see the following sites with photos/videos/descriptions of other Tacoma owners having the exact same issue. Thank you very much for your time.

After a couple of years of owning my truck, the paint started on my hood and roof started to turn white and fade. I don’t understand why Toyota uses this type of paint that’s going to get messed up after a couple of years. Also after 4 years of owning the truck, the suspension is all messed up (never took the truck off road or driven it anywhere else but the streets and now they make noises like crazy

The clear coat on the exterior paint of the truck has failed. This has left the base coat paint exposed which means the metal frame is susceptible to rusting now.
