Selected complaints filed with NHTSA by 2011 Toyota Tacoma owners, lightly cleaned up (personal details are redacted by NHTSA).
Blower Fan had been cutting off. Only running intermittent on High. Took to Toyota dealer June 2025. Was told it was a Cabin Air Filter Clogged. Paid for replacement and clean out of system. Continued to not work. Called a mechanic and asked for a diagnostic. Was told it was a "known issue" with Toyota Tacomas. Had been a recall in later years. I ordered the blower motor resistor and wiring harness from Toyota parts department. It was on back order due to the issue being widespread. July 2025 parts came in. Returned truck to the shop. The techichian replaced the motor blower resistor and the new wiring harness. However, he cut the burnt wires off and spliced the new wires into old wires back to the motor. Aug 2025 motor has stopped working again. Back to the Toyota shop. The truck needs a new blower motor. The labor will be 1200. …
Tl* the contact owns a 2011 Toyota Tacoma. While driving at various speeds, the fan stopped working. The contact also smelled an abnormal burning odor coming from the vehicle. The contact checked behind the firewall and the wiring harness and wiring were burned. The contact stated that the day time running lights were melting along with the fixtures and wires in the back of the bulb. The vehicle was taken to the dealer where the contact's diagnosis was confirmed. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 80,000.
This VIN number was totaled due to a bent frame after being rear ended on June 10th. I fear my insurance company (USAA) will attempt to commit fraud by not reporting the title as salvage.
Horn stopped working at approximately 48,000 miles. After troubleshooting the problem, I discovered that the issue was related to the spiral cable. About 2 months after the horn stopped working, the steering wheel controlled phone function began auto-activating intermittently with the words "talking" appearing on the radio display (this function is also related to the spiral cable). I am very concerned that the air bag May soon become inoperable if the air bag electrical contacts on the spiral cable fail. While my vehicle VIN was not included in a recall for this issue, I understand that Toyota did file a part 573 defect information report with NHTSA for selected 2009-2010 Tacoma vehicles. The vehicle horn is considered a safety device, and as a result of this failure, my vehicle horn became inoperable. …
My horn does not work when I press on the steering wheel unless I turn the wheels to the right or to the left then it will work. I took in my truck to the Toyota dealer and they told me this is not covered under the warranty and that they will have to charge me $130 to look at it. I told them that this is a safety issue. When I am driving and something happens and I have to beep someone I cannot do that no matter how much I press on the steering wheel. I bought this car new. I owned other cars before but this is the first time I drove a car with no horn. To me it seems to be a manufacturer issue I believe Toyota should repair this at no charge.
Sudden unintended acceleration. Time was 6:55 am. I was on work property having just turned left from a light. I was 5 th car in line to make a right turn. All cars were stopped. My foot was lightly pressing break. The next thing I know, my truck was ramming the SUV in front of me. No way my foot could have touched gas pedal...it was a traffic jam. It's like this every morning. I contacted Toyota right away. They denied it, but sent out an eng to get black box data. I never heard from them again.
Tl* the contact owns a 2011 Toyota Tacoma. The contact stated that while driving approximately 65 MPH, he could smell a burning odor coming from under the dashboard area. The vehicle was merged to the shoulder and suddenly became engulfed in flames. The fire department was called, who arrived and extinguished the fire. The origin of the fire was unknown. There were no injuries and the vehicle was destroyed. The manufacturer was not notified of the failure. The failure mileage was 32,500.
Driving down the highway, I felt my steering column get loose. After coming to a stop at the gas station, I tried making sure the column adjuster was tight, and it was. The entire steering wheel/column was still loose, and then fell off into my lap. After that, my Tacoma would not start. Radio would not work, and the odometer numbers disappeared. I had to then call a tow truck to get my vehicle home. If I hadn't stopped at at the gas station, it would have fell off as I was driving.
Tl* the contact owns a 2011 Toyota Tacoma. While driving various speeds, the horn failed to work without warning. The vehicle was taken to the dealer where it was diagnosed that the spiral cable needed to be replaced. The dealer stated that the repair would cost $500. The vehicle was not repaired. The manufacturer stated that there was no recall and could not assist. The failure mileage was 48,000. Updated 06/29/17
My vehicle failed va inspection due to the horn not working. I have to get the spiral cable replaced per the auto repair shop. This was a recall on Tacoma's up to 2009 (recall b1801) but not my year. My year should be part of the recall. I believe this also impacts the airbag deployment from the steering wheel.
