2017 Toyota Tacoma

Common issue reported amongst 2016-2019 Toyota Tacoma owners. Noticed brake fluid dripping from under driver's side dash directly under brake pedal onto floor mat. Upon inspection, found brake fluid dripping down from what appears to be brake booster. Leaking brake booster should be a safety recall with replacement covered by Toyota.

Truck has 116k miles, started losing power and acceleration diminished. CEL and Trac Off light came on. Pulled over twice after experiencing same issue. Took to mechanic and diagnostic code P0301 (cylinder 1 misfire). Replaced 6 spark plugs to be safe, and replaced broken coil in cylinder 1. Drove less than a mile and CEL came back on. Brought to dealership this time and they found a leak in the head gasket and noticed warping in cylinder 1, along with code P0301 still present. They reported back to me stating it needed a machinist to resurface the the cylinder head, that the repair is mechanical. Even outside of warranty this fix should not be costing $13,000. The truck has been properly maintained for the past 9 years, all oil services and replacing any wear and tear items. Mechanical (warping) is manufacturing issues.

Clear coat and paint began to oxidize and fade after 4 years of ownership even when maintaining with wax

The contact owns a 2017 Toyota Tacoma. The contact stated that while driving, the engine revved lightly. Over time the vehicle began to lunge forward, and the revving had become more intense. The RPM increased and revved. While reversing, the vehicle lunged. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the failure was due to the map sensor and throttle body. The vehicle was repaired, but the failure recurred. The manufacturer was not notified. The failure mileage was approximately 75,000.

Water leak from cabin pressure vents behind rear seats. Water leaks directly into carpet causing unknown mold growth. This mold growth is a safety issue due to the cognitive and respiratory problems associated.

Product identification: Brand: Dasaita Model: HA2161H3 ASIN: B0CQNWQR8D Purchased: September 4, 2025, via Amazon Aftermarket Android head unit installed in a 2017 Toyota Tacoma TRD Sport caused electrical interference with the vehicle's brake stop switch circuit (DTC C1425), resulting in autonomous braking without driver input, simultaneous ABS and Traction Control warning lights, and a dashboard warning indicating simultaneous accelerator and brake input. Two independent repair facilities confirmed the head unit as the probable cause. Symptoms resolved upon removal of the head unit and reinstallation of the factory OEM unit. The product is currently listed as unavailable on Amazon. Injury or accident: None, but describe it as a near-safety incident since the vehicle was braking itself while in motion.

Vehicle stalled on highway bridge. Took to mechanic shop. They put the diagnostic code machine on and the code indicated fuel pump failure. Toyota does have a recall notice for the year, make, and model of my vehicle. But not showing on my VIN.

My 2017 Tacoma extra cab has paint peeling around the both windows and both fenders. Toyota states the four door trucks are covered under the customer support program 23TE08 but the extra cabs are not. My truck currently has 13,500 miles. They need to include the extra cabs.

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.

Premature factory paint and clear coat failure on Toyota MGM paint. Issue affects vehicle value and body protection. Manufacturer notified.

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!

Truck does not accelerate fully when I hit gas pedal. The truck stalls and my gas consumption is off.

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.
