We are a surveying company with a fleet of 35 Toyota Tundra trucks. Two of the trucks in our Denver location have had the engine wiring harness chewed and destroyed by rodents in the parking lot. Each is costing $6,500 to repair. The second truck shorted out and the check engine lights came on, would not start. I am glad this did not fail while someone was driving it. Toyota uses a flexible pipe wrap over some of this wiring that is soy based; the plastic wrapped wiring is unaffected. This problem is well documented on the internet, and very common. Toyota is profiting in a big way from this design defect, and they are compromising safety by risking engine failures due to shorts. They should be forced to install hard plastic wire covers over these harness wires to prevent this damage.

On two different occasions I was driving my Tundra on the freeway at approx. 70 mph. My truck lost power and I almost caused accidents on both instances since I could not accelerate past 40 mph. I had to manage my way out of the freeway to a safe place. 2two diagnostics were performed and I received codes P0418, P1604, C1241, P2445, P2441. I was told by the Toyota dealership that there was a problem with a faulty secondary air injection system pump and other components related to the system and I was provided a repair cost of over $3,000 dollars. I was later informed, and I discovered through research, that Toyota had installed faulty/defective air pumps in thousands of Tundra 2013's like the one that I own. I reached out to corporate office but they stated that my VIN number somehow did not "qualify" as one of the affected pickups. My Tundra only has 60K miles and I use it to commute from and to work basically. I perform routine maintenance. There is obviously a problem with a defective secondary air pump system that Toyota refuses to fix. My truck is a liability on the road and this is my only means of transportation. It looses power and the check engine light activates. Toyota recalled thousands of vehicles like mine and fixed them after they acknowledged that they had placed faulty air pump systems. My truck is a potential possible cause for an accident since it unpredictably looses power on the freeway. I have not received a solution from headquarters/corporate office to repair my truck at no price since it is affected by their faulty pumps. They did offer $750 dollars towards the cost of parts, meaning that I have to come out with over $2000K out of pocket. I need Toyota to take responsibility and fix my truck.

Initially driver side lock actuator would not unlock door via remote. This last approximately 10-days. The problem resolved it self. Approximately 2-weeks later the front passenger door exhibited the same problem. The passenger door lock actuator problem lasted approximately 7-days. This has been randomly happening over the past 6-8 months. Within the past 5-days the drivers door began acting up. This time the lock would unlock using the remote but then would not lock using the remote. I would have to cycle the lock system 4 to 5 times before all four doors would lock using remote. At some times three of the four doors would lock except the drivers door. I then tried to recycle the lock system. At times after recycling the lock system I would still have to lock drivers door manually. I took vehicle to Toyota dealer in my hometown, the diagnosis was that both front door lock actuators are bad and I would need to spend $1,200 to fix. I was told the lock actuators are not covered under any manufactures recall. The lock actuator issue has always happened when vehicle is in a parked condition, engine off. It has happened in all kinds of weather.

The truck horn does not work when pressing on the steering wheel. It will work when the panic button is pressed. I bought the truck from the original owner, a friend of mine, and he believes it never worked. My brother has a similar Tundra 2014 model and his horn has started working only intermittingly. I believe this may be a common problem.

The contact owns a 2013 Toyota Tundra. While driving at approximately 60 mph, there were flames coming from the fuel lines, the engine compartment, and under the vehicle near the rear windows. The fire department was able to extinguish the fire. A police report was not filed and there were no injuries reported. The vehicle was towed to the contact's residence. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 40,000.

The body of the truck is designed to allow rodents/mice into the cab where they can chew the wiring which will lead to a variety of problems. The truck currently has about 3300 miles on it. When I contacted the dealer they said yeah all these trucks have this, what has been damaged so we can get it in for repair. I asked if it was covered under warranty and they said no. Coating the wiring with a soy (mouse food) based product is insanity unless you're trying to increase your repair business. There are 16 computers in this truck that control everything. When the wiring is damaged because of this design flaw all sorts of malfunctions will occur that include steering, engine quitting, brakes failing, throttle, lights, etc. The dealer is very aware of the problem and specializes in fixing it to the tune of about $200 so far. I haven't had a wiring problem because of mice but others have. This very funny (to the dealer0 problem will eventually kill people if it hasn't already.
