2017 Toyota Tacoma Complaint Log

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.

There is a leak the rear differential. There is a recall on this issue

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.

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

The contact owns a 2017 Toyota Tacoma. The contact stated that while operating the vehicle, it was discovered that the front driver’s side heated seat was inoperable, and the seat was not heated while the switch for the heated seat was activated. Upon inspection, the contact discovered that the electrical wire connector and wiring harness had melted and was destroyed and that the heating components inoperable. The manufacturer and local dealer were notified of the failure and informed the contact of a Technical Service Bulletin regarding the failure, but no assistance was offered. The vehicle was not yet repaired. The failure mileage was 65,000.

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. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 87,000, and at the time of registration, it was discovered that the mileage was 220,717.

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.

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.

Unit 1 vehicle ran a red light at approximately 45mph and impacted the passenger side door of the Tacoma (unit 2) pushing the Tacoma into a stop vehicle (unit 3) in the turning lane. Unit 1 and unit 3 air bags deployed but none of the air bags in the Tacoma deployed. One of the pictures taken show the front driver side air bag sensor in the wreck frame.

BRAKE FLUID LEAK SEEPING FROM BRAKE MASTER CYLINDER, LEAKING FROM ACTUATOR TO BRAKE PEADAL AND DRIPS OF FLUID FOUND ON FLOOR OF VEHICLE. This is an obvious safety risk as not only is oil/fluid dripping on to the brake pedal, if the master cylinder goes out the brakes could stop working completely. This component has been inspected and confirmed by a Toyota dealership and there are other examples of this same issue happening to other Tacoma owners. This issue has been recalled on 2018 Toyota Tacomas, however, the recall needs to be expanded to more years as it is obvious that other Tacomas are being effected.

2017 (manufactured in June) model year Tacoma vehicles painted with 8T0 Blue Metallic exhibit clear-coat peeling on one or more panels. The peeling occurs in the clear coat layer, exposing the base coat to the sunlight and fading the color to white. There is a current TSB #T-SB-0004-20, but Toyota says my vehicle was manufactured outside the affected Production range, as you can see in the attached, my vehicle's clear coat peeling looks exactly as described in the TSB. I have seen online other people are experiencing this pushback as well from Toyota. This TSB should be extended at least through June of 2017 if not through the end of the year. Toyota is REFUSING to make the repairs.

Paint is peeling around doors on both sides of the vehicle. Both front and rear doors of the cab. Common known issue.

2017 Toyota Tacoma double cab-V6 with 62K approx miles. On or around April 29th 2024, I was traveling in this truck when there was a sudden and complete loss of power, two check engine lights came on-The "trac off" light and the check engine light came on. I needed to pull over immediately for safety. I ended up driving the vehicle to the Toyota dealership in limp mode. The vehicle has sat at Tustin Toyota now for weeks with the Toyota dealership initially suggesting that a ACIS Flap broke off inside the intake manifold of the car. This was replaced and the vehicle is still providing the same alarms and still in limp mode. The initial fix(whihc did not fix the problem was a full replacement of the intake manifold). Now the dealer is suggesting that a piece(s) broke off the intake manifold and ended up inside the engine so now dealer is recommending and entire engine break down to attempt to further diagnose the situation. Again it looks to be a complete failuure of the ACIS system and the intake manifold. This problem has presented a EXTREME safety issue due to comp[lete loss for power initially then truck sits in LIMP Mode. Very dangerous!

Brake master cylinder is leaking into the lower dash area and onto the floor mats.

The Tacoma still has only 10,000 original miles. We yearly replace the oil when we have our annual vehicle inspection. The truck has been trouble since the beginning. Early on I noticed when going downhill, the automatic transmission seems to slip when applying the gas. I have taken the truck back to the dealer in Kona to be told that it is not part of the rear end differential recall some years ago. I asked them to make a notation of this should the transmission or rear end differential fail in the future. Recently, we received an informational letter from Toyota regarding something about a possible faulty high pressure fuel pump. I made an appointment at the dealer and since I was there asked them for tire rotation, oil change and annual vehicle inspection. I explained to the service writer that I still believe there is a rear end or transmission problem. At first, she said, the recall was never done and later said it was done. More importantly, I have been smelling gasoline when I exit the truck although I see no visible fuel on the ground. I believe that this is related to the fuel pump issue which I received the letter from you. I was told several hours after I dropped off the truck that the fuel smell was not related to the letter I received.

CUSTOMER SUPPORT PROGRAM 23TE08. The initial notice went out, I need to know a remedy or at least a timeline of events. I'm attempting to trade my vehicle and this paint issue is affecting my trade-in value. In addition to the paint peeling, I've also encountered several random circular areas of dull paint in different areas of the truck. the paint issue needs addressed.

The brake master cylinder is leaking to the inside of the cab floor.

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 have started to notice that my 2017 Toyota Tacoma Off-Road has started to leak what seems brake fluid on my carpet. After inspecting my vehicle, I have noticed that the leak is coming from the Brake Master Cylinder. This situation has me worried now that this could lead to a serious accident. There is an apparent recall for this same exact issue for the 2018-2019 Tacoma models but, not for the 2017 model year.

Brake system is leaking fluid into the cab, and collects on the floor mat. Brake fluid level has dropped below minimum cold level. Mileage 42,164 Leaking brake fluid can cause decreased brake performance, or complete failure of the braking system. Which can result in loss of vehicle control and collisions with other vehicles, structures, or pedestrians. The dealer has not yet confirmed the issue. The vehicle has not yet been inspected by anyone other than the owner (myself). No warning lamps or messages. Leaking brake fluid was seen on the driver floor mat within the last few months, and continues.

Rear coolant bypass joint leak. This is a plastic defective pipe that has leaked on my truck and thousands of others! The dealership wants 2000 dollars to repair their cheap mistake! I have pictures and invoice to upload, but the site will not allow it.

Brake pedal spongy and when pushed and held it continuously goes slowly to the floor. I believe the recall for the master cylinder should have been extended back further.

The contact owns a 2017 Toyota Tacoma. The contact stated that, upon coming to a complete stop, the vehicle suddenly accelerated on its own. After which, upon attempting to apply the brakes and with the brake pedal depressed to the floorboard, the vehicle failed to stop, prompting the contact to switch off the ignition. As a result of the unintended acceleration and brake failures, the contact collided with the rear quarter panel of another passenger vehicle. The air bags did not deploy. No warning lights were illuminated. A police report was filed, and no injuries were reported. The vehicle was towed to the dealer, who was unable to diagnose the failure, informing the contact that the event data recorder showed the accelerator pedal had been depressed. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 80,000.

The 2018-2019 Toyota Tacomas have been recalled for having a bad Master Cylinder and leaking internally within the truck. The 2017 Tacomas have the same issue. My 2017 Tacoma has been leaking brake fluid on my floormat. I'm sure I am not the only one having an issue with this and because it involved the brakes it does pose a risk on the road If the brakes were to fail due to a Master Cylinder that again has been recalled with the 2018-19 Tacomas. Why not include the 2017 Tacomas as well?

I have noticed brake fluid leaking inside the cab coming from the master cylinder. I see that 2018-2019 models have a defective master cylinder, and a recall has been issued. Truck has 80,000 miles, thinking the 2017 model should be added to the recall. Very unusual for this to be leaking under normal use. Thanks for your time

The contact owns a 2017 Toyota Tacoma. The contact stated that while operating the vehicle, the check engine and traction control warning lights remained illuminated. The vehicle was taken to the local dealer who diagnosed that engine cylinder #2 was faulty, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 101,000.

BOUGHT THIS TACOMA TRUCK NEW FROM THE DEALER. IT NOW HAS 16,885 MILES ON THE TRUCK AND THE DEALER TELLS ME THE FRONT BRAKES ARE IN THE RED, BAD RANGE, 3/32" OR LESS IN THICKNESS AND THEY NEED TO BE REPLACED SOON. I BELIEVE IT'S COMMON KNOWLEDGE THAT BRAKES ON A NEW VEHICLE REALLY OUGHT TO LAST TWICE THAT MANY MILES. NOW IT BEING A SAFETY ISSUE I WAS NOT SURE IF I SHOULD REPORT THIS TYPE OF ISSUE?

Purchased 4 new Firestone Destination LE3 P245/75/R16 tires. I immediately noticed my truck vibrating a lot. The higher rhe speed , the bigger vibration. I took it back twice. The service tech. Indicated that he balanced them, so i took them to another service station. Two front tires wrre determined to be egg-shaped and could not be balanced. They were also noticably a different color than the back two tires as well. I am taking them back to the original seller and having them replaced under the warranty.

Transmission line was described by two auto mechanics (one from a Toyota dealership) as “rusted out” and “porous”, “low pressure/fluid” and “needs to be fixed”. I was totally unaware of the issue until I had to get my AC recharged. Note: this is a 2017 truck with 82,000 miles driven in Massachusetts. No warning lights went off.

Master cylinder or some part near brake pedal inside the cab is leaking oil or a oil like substance on to floor mats and floor.

Not a safety issue. The clear coat seems to be fading on a lot of the 3rd gen tacomas from the factory. Fades much faster than it should.

We purchased a set of these tires at the end of June and have only about 15,000mi on them now. The embossed tire wear indicators show more than the 80% tread life left. About two weeks or so ago, I noticed a blister on the tire. Looking at it, there were a few tread blocks separating from the carcass. Yes, separation like what caused issues with Firestone and Ford Explorers a while ago! Pictures attached. I tried reaching out directly to Nokian and received no reply. I then tried to contact the seller (Budget Center) and Amazon. Initially, Amazon was helpful and the seller told me to go check at a local store. Now, Amazon says there is nothing that they will do and I have to go through Nokian on my own. Note that I was not asking for a refund, only help contacting Nokian. We have purchased several sets of tires from Amazon and will never again if this is how they handle warrantable defects. Shameful! The consumer was able to get in contact with the manufacture and the new tire is now installed.

It has been well established among 2016 and up Toyota Tacoma owners and clubs that the Rear Coolant Bypass Joint leaks at different mileages, If the loss of coolant happens rapidly enough the engine could overheat and siez up and cause the pistions to weld to the cylinders along with causing extensive engine damage not to mention how the driver would handel the truck, Toyota dealerships and Manufacture also know of This Coolant Bypass joint leak and how common it is. Also the corrosive build up from the antifreeze will cause other parts and wires to not work, Attached is my part and the build up of antifreez before the leak,

Paint is chipping off around rear passenger door On my White 2017 Tacoma, and Toyota wont do anything about it. Paid for paint protection coating for no reason i guess. I am not the only owner going through this there are petitions and forums all over internet too. Toyota should have to fix this problem. We noticed it about 6 months ago and it is steadily getting worse, I am afraid to wash it fear it would get even worse.

Excessive peeling/flaking paint on all 4 doors, hood, gas cap, all over.
