2017 Toyota Tacoma

On Tuesday, April 14, 2026 I was looking for something in my rear seat and noticed the seat was damp. I couldn't figure out the cause so I goggled it and found out that Toyota had a limited service campaign called LSC21TD03 on my 2017 Tacoma because of the third brake light having a gasket issue causing water to enter the vehicle. I called a local Toyota dealer and was told that the fix for my vehicle had expired in 2025. This water intrusion from the high third brake light can cause mold, interior damage, or electrical issues. This is an issue that Toyota previously acknowledged but has now stopped covering it. I called Toyota Corporate and was again told yes the repair fix was expired. I asked why wasn't I notified and was told that Toyota sent out letters. I told the representative that I never received a letter and was told the mailing was done by an outside company. I asked what could Toyota do to help me and was told to go back to the dealer and maybe they "would give me a discount or reduced price on the fix". The dealer offered nothing. Upon further research I found that several Toyota Tacoma owners state they were not aware of the service campaign and ended up changing the light themselves or paying out of pocket to have it repaired. I feel that this is an issue that Toyota is aware of and they should take care of it. This should have been a recall issue rather than just a service campaign that the public was not fully aware of. I still don't know the extent of damage to my vehicle because the dealer gave me a quote of $690 to repair. I questioned why so much to change a light and gasket and was told they have to take the panels down and clean the vehicle to make sure no mold was there. The quote was given without even examining the vehicle. I'm asking you to please look into this situation.

2017 Toyota Tacoma painted in MGM (MG1). The trucks paint/clearcoat are quickly failing from the factory paint application. This is a garage kept vehicle with 75k miles. Toyota refuses to accept any ownership of the factory paint application. This is a common issue amongst all Tacoma's, regardless of year or color.

Have had engine issues such as stalling, rattling, limp mode, rough idling and engine missing. Have had repairs done but continues to have major issues where it is not functioning properly.

I was driving on the highway when my vehicle suddenly lost power. The engine light and traction control light came on, and I lost power, and the engine started sputtering. I had to pull off to the side and put on hazards. My Tacoma would only drive about 25 MPH after this happened. Based on a quick search, this is a very common problem in 3rd-generation Tacomas!

Fuel leak at the fuel lines at the rear connection near the fuel tank, drivers side rear.

Clock spring has failed. I've lost all steering wheel button controls as well as cruise control. Air bag light has now come on. I am afraid that if I get into a wreck, the airbag will not deploy. This seems to be a common issue with this select year for this Tacoma.

Odometer Fraud. The contact purchased a 2017 Toyota Tacoma. The contact stated that while attempting to register the vehicle, it was discovered that there was a mileage discrepancy.

I was driving my 2017 Toyota Tacoma and I my car suddenly was lurching and running rough. I had to put on hazards on a main road and pull over immediately and was not even able to let it run for air conditioning. It was 108 degrees out that day, waited for 1 hour 30 minutes in heat. Had truck towed to mechanic that stated my fuel pump was bad and there was a federal mandate recall on this. I have the paperwork for this (attached), when I called dealership they said it was not covered so I called advocate for Toyota that stated my truck was built in June and the mandate was only for September of 2017 and forward. So I have the exact same problem that they have a federal mandate to fix but won't fix mine. If I had been on the freeway I could have been killed. I have attached estimate to fix.

Hi there, I am reaching out as I am super frustrated. I received a text from Capital Toyota stating my 2017 Toyota Tacoma had a safety recall for a water leak. I contacted the dealership and they told me my vehicle wasn't eligible for this recall to reach out to cooperate, in which I did and they told me it was only for certain vehicles. However I have been texting with the service dept at Capital Toyota and they are saying it was apart of the recall but it has expired. Now I am left with a constant leaking from the third break light, and I have a [XXX] baby and it is a huge safety concern as mold is a serious health hazard. I can be reached at [XXX] if you need further information. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Brake oil leak from brake booster. Oil goes into the cab and oil leaks behind the break pedal onto the floor mat.

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.
