Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2015 Toyota Tacoma Owner Comments

problem #5

My truck was recently damaged from rodents, they built a nest by engine and chewed wires. After further research I found that auto manufacturers in order to go green are using soy based products on wires instead of petroleum. They are using sugar in there plastics. Rice husks in there interiors. All this stuff attracts rodents. This is unacceptable! my dealership said they are seeing at least 2 rodent damaged vehicles a week. My truck is driven daily and sits no longer than 8 hours. The total damage on a brand new truck with extended warranty was 2700 out of pocket, this damage was no covered by warranty.

Secondary air injection system malfunctioned at under 8K miles on a 2015 brand new truck. Did some research and this part seems to fail pretty early and just outside the 3year/36mos coverage and be quite costly to fix or replace. Toyota currently is not doing anything about it on Tacoma like they did with the Tundra but they are aware that this part is prone to failure.

I was driving straight away going up a slight hill on the hwy excelling and pressing the gas pedal when the power suddenly dropped and went down to 20 mph while I pressed the gas pedal even more the engine sounded like it was revving but the speed stayed at 20 mph or less.- the check engine light, vsc & trac lights all came on. I immediately pulled over and decided to turn around and not continue up the hill. While driving on the straight away (still on the hwy) the vehicle's speed improved a little but only in spurts- going upwards to 40 mph then falling again to 20 mph at least 3 times in the 20 minute drive home. The vehicle sounded and felt like it was straining for power. All of the fluids, oils etc.. was filled and in good standings- this vehicle is only 6 months old and has 4434 miles on it. I took the vehicle to the Toyota dealer the very next day and they found that this was a manufacturing problem. The codes P2445 and P2441 was found faulty and was replaced- in the report it was stated that the car is down, considered unsafe to drive because the vehicle may go into limp mode for this condition while driving. I am submitting a portion of the report with my personal information covered.

The contact owns a 2015 Toyota Tacoma. The contact stated that while driving at 40 mph, the accelerator pedal was depressed and the engine stalled without warning. The failure was persistent. The vehicle was taken to a dealer where it was diagnosed that the wiring failed and needed to be replaced. The vehicle was repaired but the failure recurred. The manufacturer was notified of the failure. The failure mileage was approximately 5,000. The VIN was not available.

Electrical wiring was eaten by some kind of rodent - twice! dash panel lights came on, so I took it to the dealer since it was new. Dealer reported that the electrical wiring had been eaten by some kind of rodent. The repair was make ($500.53 discounted), and the first night the truck was back in front of the house - it happened again. We live in the city with many vehicles parted in the street. I have lived in the same house for over 27 years and have always had a vehicle parked in my drive way with no rodent problem. Why now" why this vehicle" according to a dealer service person (and collaborated on-line), car manufacturers (Toyota included) are trying to become more "green" and have begun using more peanut and soy products in the manufacturing of its wire insulation and rubber hoses - thus attracting animals. Also, the design of this V6 engine has a space just under the engine cover that small animals fine inviting and warm. The animal go into this space and naught on the wires that are present. My local dealer covered the second repair, and was great to work with. However, there seems to be a design/manufacturing issue that is out of the control of the dealer. My solution = fill the space with chicken wire. So far. So good.
