2017 Tacoma TRD Pro Water has been leaking through the rear air-pressure vents for quite some time. I have had a moldy/musty smell in the truck after a good rain for at least 6 months. Then I started noticing mold coming up on the driver's side kick plate. We went through all the diagnostic steps with Toyota dealership, who kept telling us it was the windshield leaking. We had the windshield removed and reset. The windshield people told us it was the cowl under the windshield allowing water to come in through the air filter behind the glovebox. We took it back to Toyota dealer and they could not find the problem. I paid them $165 to "not" diagnose my truck. They also handed me an estimate for $11,000 to remediate the mold. When we got the truck home, we started looking up the problem on Tacoma forums and YouTube and finally discovered it was the air vents behind the rear seat. I pulled the plastic molding back and there was tons on mold. I took it back to the dealership for repair. The dealership has now said they will replace the air vents but will not remediate the mold. I have had sinus trouble for more than a year and did not know why. I believe this is the reason.

I had noticed my heated seat stopped working. Upon investigation and searching the web for similar issues I found that a relay for the seats located under each front seat was the issue. I saw pictures online of others and when I pulled my seat out I found the connection between the wires and relay had been completely burned and melted. This is Toyota part number 87501-0C020. When looking up this part it is discontinued with no replacement. There-??s no recall or warning from Toyota for this issue. This same part is also installed on Tundra too. By the amount of burning this is definitely a safety issue and I don-??t know why it has not been addressed.

Seat heater not working. i looked online to see what the issue could be and learned there was issues with the seat heater amp burning up from being defective. I pulled the amp and noticed the amp was burnt up and so was the wiring. This is a fire hazard.

Noticed that my floor is getting soaked for no reason. After bring my truck to Arlington Toyota I found out that is was the cabin pressure vent that was leaking. The cabin pressure vent is found between the truck bed and cab. They recalled the third break light in 2019 for leaking water into the cabin but Toyota won-??t recognize this pressure vent as a recall which is also leaking water into the cabin. After pulling up all of the carpet I have black mold all under the carpet where my newborn baby was riding. Black mold is a huge health concern. Looking online this is a known issue with Toyota tacomas. My parts to fix this issue have been back ordered for two mths so far, still with no ETA on when they will be available. According to The service rep, I am one of nine people currently dealing with this same issue at Arlington Toyotas dealership alone. so no time frames have been provided. When I was quoted the 5800 to fix this issue they suggested I go through insurance. This seems to be a known issue with product quality and instead of recalling they are pushing it to insurance Companies. Seems to be a shady practice Toyota is pulling and no one is big enough to stop them.

Purchased truck July 24, 2017 from mark miller Toyota in salt lake city, Utah. In the first 6 months I lost brakes 3 times. Went to dealer each time. They couldn't duplicate so no repairs made. After the 3 times a recall came out, 18V888. Exact symptoms. Then a forth time happened and they said the recall doesn't effect my VIN so they still have to duplicate. Today, February 27, 2019 truck wouldn't stop and I ran thru a stop sign, and it was cont on my dash cam. With this problem my seats are loose and sometimes don't lock. When ever in 4 wheel drive the seat belts lock up and wont unlock lock. I've had nothing but issues with this truck and nothing will ever get fixed and I'm scared to drive my vehicle especially when my dealer won't repair anything. Also believe it has something to do with the vehicles off-road option, crawl control, which uses ABS.

Front seat head rest will not stay in position - keep moving up by itself.
