“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. …”
NHTSA complaint #10824105, filed 2016-02, 4,434 miles“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. …”
NHTSA complaint #10872591, filed 2016-06, 17,000 miles“On three different occasions I was stationary with the gear shift in drive and my foot firmly on the break,when the RPM's suddenly revel up to over 5000 RPM and the truck trying to lurch forward. I had to ram the gear shift into neutral to get the RPM's to drop down. The last time it happened at the bank parking lot. I came to a complete stop to let a woman cross in front of me to her car. All of the sudden the engine revs way up with me trying to hold the truck back as it was lurching forward. She thought I was trying to run over her. I don't know who was more scared, her or me. …”
NHTSA complaint #11343429, filed 2020-08, 63,000 miles“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? …”
NHTSA complaint #10668292, filed 2014-12, 670 miles“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 tacomas like they did with the tundras but they are aware that this part is prone to failure.”
