“The trac off and check engine lights come on periodically. I have to disconnect the battery and take the gas cap off and put it back on and reconnect the battery when it happens. Its a pain in the butt. I thought I saw a recall for the gas cap seal to correct the problem, but the dealership said nope.”

“Driver’s side front seat not delivering heat despite switch lamp indicating it’s on and working. Further exploration reveals passenger side seat heater working as it should. I checked wiring harness and connections under driver’s seat only to discover plastic connector entering amplifier scorched and melted with two of four pins destroyed (Red and Green wires). I believe the wire gauge sized for this system is improper and therefore represents a fire hazard. …”

“Toyota pushed an ota (over-the-air) that caused firmware and completely disables the onboard navigation. Presently, I now have 'driver easy speak' out of the blue and that the 'software is incompatible' on my head unit's display. This upload has disabled various Toyota models across the board. Contact with various Toyota dealers has been a waste of time. A letter sent to Toyota corporate has been fruitless. The dealer wants to replace the navigation unit for $1000!”

“My ABS light failure came on and said check with dealer. Three days later taken to dealership and electrical harness had been chewed by rodents. It is requiring $5000 to replace this component. I have had this truck for one month and brand new. The vehicle was stationery in driveway when eaten.”

NHTSA complaint #10837402, filed 2016-02, 1,300 miles

“The bluetooth on the iphone 11 pro max and the Tacoma are not communicating causing a safety issue, because I can not talk hands free as I am suppose have the ability to do so. The entire headset will turn off and on constantly , the only way to stop this is to either turn off the bluetooth on the iphone or remove the iphone from the Tacoma. I have read on line that many people are having the same issue and either Toyota or apple is doing anything to resolve it, causing a saftey issue.”
