As if it didn’t have enough on its plate, Toyota is now coming under scrutiny for denying an extended warranty to owners of 2001-03 . Toyota began an inquiry into the issue last August after more than 300 complaints were filed with the National Highway Traffic Safety Administration. The complaints involved the vehicle jerking, failing to accelerate or suddenly slowing down. Many of the complaints included descriptions of the transmission failure as “dangerous” and “scary.”It’s important to note that drivers can severely damage their transmissions just by driving poorly and that the transmission is covered under Toyota’s powertrain warranty of six years or 60,000 miles.
