Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“In late november or early december of 2020, I had a check engine light appear. I cycled through several hundred miles (500+) thinking it may have been a loose gas cap issue that needed time to sort itself out. The light did not resolve itself and I visited the closest dealership, autonation Toyota, in tempe. I was surprised to learn that there was damage to the engine wiring harness caused by rodents. Many manufacturers, including Toyota, have switched to soy-based wiring insulation which is attractive to rodents. …”
NHTSA complaint #11404754, filed 2021-03, 6,200 miles“Vehicle struggles to start with normal starting procedures. Vehicle's ignition delays normal starting procedures sometimes allowing the key to be held systematically for an abnormal period of time before vehicle starting. If vehicle fails to start in the first try within 3-5 seconds vehicle would crank but would not start. Then a second attempt would have to be made. This is not common for a gas engine vehicle . Was taken to dealer for further inspection and service advisor said this is normal for most late model tacomas.”
