Rodents ate through eleven soy base coated wires. These wires just so happen to go to the fob, my air conditioning, and one headlight. This is obviously a safety issue. I contacted Toyota and filed my concerns. They told me that there is nothing they could do. I at the least would like a reasonable explanation why they engineered food into their electrical system. Thanks for listening.

Design defect resulting in inability to open hood. Battery failed (subsequently replaced by dealer under warranty) but could not open hood to jump start. Tow operator could not open hood either, so vehicle had to be towed to dealership. Per dealer employee, design defect results in hood bumpers easily going out of adjustment, preventing ability to open hood. This is an extreme safety issue, since in a vehicular accident when fuel is or may be leaking, the battery must be disconnected to prevent a fire, especially when occupants are stuck in wreckage pending ems arrival. I have had this happen to me, likely saving lives and certainly preventing catastrophic burns. The bumper is clearly designed this way as a cost-savings measure, so that the bumper can be used for various models and makes. The bumper's design has almost unlimited adjustment, and easily comes out of adjustment. This defect can be easily corrected by securing these bumpers with an adhesive or other means.

I was driving at about 40mph on a country road with no vehicles in front or behind me and the warning to brake along with the associated beeping and red blinking lights on the dashboard appeared. This went away after about 2 seconds. It was like the vehicle sensed a car in front of me that I was going to hit but there was nothing in front of me whatsoever. The brakes never engaged but the warning caused me to jump. If I was in a congested area or on the highway it could have caused me to lose control or swerve into someone/something.

There have been several times I have gone out to my tacoma that I can hear the fuel pump running on it's own. I heard it running one evening, while no keys were inserted and the truck was locked up. The truck runs rough most of the time and I have problems with it stalling and not wanting to start back up again. It will take 3 to 4 times turning the truck over before it will reluctantly will start up. Also the traction control button does not work anymore and the differential button when pushed on does not engage the differential. All of these issues have started at different times. The fuel pump running when no one inside it has just the month been noticed as well as the buttons. The stalling started to be noticed about 4 months ago and I at first thought it was due to it being not broke in or me not giving it enough gas, but it is almost every time now when I back up or go forward it can stall.
