2019 TOYOTA TACOMA Electrical System Problems

Water leaked through the third brake light assembly into the cab roof, soaking the ceiling, seats, and carpet. This caused extensive mold growth and electrical corrosion near the control modules. The affected systems include the third brake light seal, cab roof, interior materials, and ECM (documentation attached). The truck remains at the dealer and is available for inspection upon request. The entire interior is contaminated with mold, creating a serious health hazard, and the vehicle cannot be safely driven or occupied. The leak also damaged electrical components, posing a risk of malfunction or short-circuit while operating the vehicle, and it is currently undrivable due to this damage. The problem was confirmed by Toyota of Clermont, which inspected the truck, documented the damage, and provided a written estimate exceeding $8,000 for repairs (copy attached). The vehicle was at the dealership while the manufacturer’s Limited Service Campaign 21TD03—issued to address this same defect—was still active, but the required inspection and seal repair were not performed. The failure of Toyota of Clermont to perform the mandated remedy under Campaign 21TD03 while the vehicle was in its possession resulted in a serious safety hazard. The entire interior of the cab—including the seats, ceiling, and carpet—is covered in mold, and the vehicle is undrivable due to water intrusion and electrical damage. There were no warning lamps or error messages before the failure, only a strong musty smell inside the cab shortly before the leak became visible. Toyota Motor North America was notified but declined responsibility. This case represents a potential noncompliance with federal defect-remedy obligations under the National Traffic and Motor Vehicle Safety Act (49 U.S.C. § 30120) and should be investigated as such.

Truck has 33,XXX miles. Was driving and the fuel gauge needle dropped to E. Dash screen stated 225 miles till empty please refuel. I tried turning it on and off, no change. Filled the gas tank numerous times, no change. Needle remains on E with warning message to please refuel. Mechanic checked and there are no codes or CELs.

My check engine light came on when I was traveling in Oregon. I didn't notice any major changes in my vehicle's performance. Drove it all the way back to Colorado without issues. It went off and came back on several times. I replaced the cabin air filter, engine air filter and put fuel injector cleaner in the vehicle. Finally I took it in to the Toyota dealership to get an oil change and then the check engine light came back on. I paid for them to do a diagnostic test and they stated they were almost certain it was the 2nd fuel injector running rich. Brought it back a week later for the repair. Fyi...I was still getting 20 mpg in fuel and I wasn't noticing anything major in performance. They replaced the fuel injector and then the check engine light came back on with a different code. They are now running "another" more expensive diagnostic test and I still don't have my truck. They are saying it could be the 2nd cylinder or the engine and claiming it has 150,000 miles so I should expect these issues (and conveniently my warranty has run out).

I currently own a 2019 Tacoma with around 70,000 miles on it. I keep up with all the Toyota recommended maintenance services to make sure my vehicle is well taken care of. So, while driving the vehicle on the interstate it drastically slowed down on its own and I could not get the gas pedal to engage almost causing a rear end collision. This also happened on two other occasions at lower speeds. My display stated I was having issues with ABS, Collision, and that I was pressing the gas pedal and break at the same time. My vehicle has been at the dealership for 4 days now with no resolve or any answers to why the vehicle is slowing down on its own. I feel the vehicle is a health/safety issue and I will not drive it until the issue is resolved. The computer was also flashed by Toyota a year earlier as I was experiencing a lag in engine engagement and high rpm's when the vehicle shifted from first to second gear. Something the tech noted he experienced driving it. It's also an issue I've had since purchasing the vehicle. I had to bring the vehicle back a month later as it started doing the same thing but was told they could not find any issues. I have found many other forums and spoke with other Tacoma owners who have had similar issues. I feel Toyota is definitely aware of the issues but not addressing them! I hope to get some answers soon!

Full tank of fuel and dashboard is showing 30 miles until empty warning. I have received the engine warning ⚠️ sign on my dashboard as well when this happens. This issue also affects me on the road when I am pressing the accelerator and the engine will not respond, this gas been an issue since they did the fuel pup recall. With a delay in acceleration comes a delay on the brake system as well, two intenses that I've had to press my foot as hard as possible on the brake to avoid a collusion with another vehicle. The last time this happened was on 4/17/2022

The contact owns a 2019 Toyota Tacoma. The contact stated while driving 60 MPH and depressing the accelerator pedal, the vehicle failed to accelerate.

The contact took the vehicle to the local dealer where the vehicle was currently being serviced. The vehicle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 42,600.

I was driving my truck a 2019 TRD off road Tacoma from San Diego to LA I was on the 605 freeway in the fast lane when I noticed smoke smell and then I noticed fire flames by the air conditioner and the phone charging plate I proceed to Exit the freeway thankfully I did not get in a car accident with any other vehicles however I was unable to stop and put out the fire. It's very upsetting because at no fault of my own I am now lob obligated to find another vehicle and I am not in the financial or credit position that I was when I bought my truck that is now a total loss by my insurance it covers my loan but not much after that so the fact that I've heard that this has been an issue for a few other Tacoma's And it's not even listed yet there's a problem the fact that this is not within my control as to what happened and there's nothing but oh well good luck getting another car Something needs to change.

DUE TO THE FACT THAT WE NEVER TEST DROVE THE 2019 TOYOTA TACOMA THAT WE WERE GIVEN TO PURCHASE, AND MY HUSBAND DROVE THE VEHICLE HOME I DID NOT HAVE THE CHANCE TO TRY THE VEHICLE UNTIL WE ARRIVED HOME. THE FIRST TIME THAT I SAT IN THE VEHICLE, I FELT EXTREME DISCOMFORT AND ELECTRIC SHOCKS FROM THE VEHICLE, VERY SIMILAR TO THE ELECTRIC SHOCKS THAT I RECEIVED FROM THE 2017 TOYOTA PRIUS. MY HUSBAND THOUGHT THAT IT WAS CAUSED FROM MY HEALTH CONDITION FROM MY CAR ACCIDENT AND HE AGREED THAT, SINCE I DID NOT FEEL ANY DISCOMFORT DRIVING THE SIENNA, HE WOULD BE THE ONLY THAT WOULD DRIVE THE TACOMA AND THAT I WOULD PRIMARILY DRIVE THE SIENNA. WHEN WE TOOK THE 2019 TOYOTA SIENNA BACK TO DEALERSHIP ON FEBRUARY 13, 2020, I WAS FORCED TO DRIVE THE 2019 TOYOTA TACOMA AND WHILE DOING SO I FELT THE SAME ELECTRIC SHOCKS AND THEY WERE MORE INTENSE AND STRONGER TO EXTENT THAT IT CAUSED EXTREME PAIN IN MY STOMACH AND BRUISES ON MY BODY. IN THE CASE OF THE SEATBELT, IT DID NOT REST ON MY NECK LIKE THE IN THE SIENNA, BUT IT RESTED ON MY ARM WHERE I RECEIVED BRUISES FROM THE SEATBELT.

ON ENTERING AN INTERSECTION THE VEHICLE APPLIED BRAKES AUTOMATICALLY AND WITHOUT WARNING. AT THAT TIME THE PATH FORWARD OF THE VEHICLE WAS CLEAR. THIS ACTION CAUSED A SAFETY HAZARD BY STALLING THE VEHICLE IN THE INTERSECTION. APPLYING GAS RESULTED IN NO FORWARD MOVEMENT. ONCOMING TRAFFIC HAD TO STOP ABRUPTLY TO AVOID A COLLISION WITH MY VEHICLE. I HAVE BEEN TO THE TOYOTA DEALERSHIP TWO TIMES TO HAVE THIS REPAIRED TO NO AVAIL. THE LAST COMMUNICATION FROM TOYOTA CONCERNING MY COMPLAINT WAS A PHONE CALL FROM A FACTORY REP ADVISING ME THAT I NEEDED TO READ MY OWNERS MANUAL REGARDING THIS ISSUE. AT THIS POINT I AN AFRAID TO DRIVE THE VEHICLE. PLEASE HELP. NHTSA REF# 247577.
