“I was driving down the highway experience loss of power such as fuel push the throttle down a couple of times it pick back up happened to more times within 10 mi1nutes it did not throw a code been checking it may relate to a throttle body problem been reading about problems with the throttle body do not want this to happen in heavy traffic or pulling out in front of traffic please let me know what or how to take care of this problem”
NHTSA complaint #10897349, filed 2016-08, 200,000 miles“While driving on the highway, I experienced an issue with the vehicle's performance under moderate acceleration (approximately 3000 RPM). The engine will no longer output power that is proportional to the amount I am requesting with the gas pedal. Once the issue occurs, the maximum power output is only 2000 RPM with the gas pedal fully pressed. The issue is occasionally resolved by shutting the engine off and waiting a few moments. The check engine light comes on with the code po120. …”
NHTSA complaint #11061554, filed 2018-01, 96,000 miles“The check engine light came on as the car decelerated. I had to depress the gas peddle to the floor to accelerate the vehicle. Took it to the dealer and they told me the choke was sticking and I needed to have an upper engine cleaning. 10000 miles later the same thing happened. Now I need a new throttle body.”
NHTSA complaint #10369556, filed 2010-12, 80,000 miles“While driving in traffic the throttle stuck at above normal idle and the check engine light came on. I was able to exit the traffic but the idle would not come back to normal curb idle. What my mechanic has told me is that the throttle body assembly has failed and they can only get the part from the dealer. If this had happened on the freeway the outcome could have not been so good. I hope Toyota is aware of this problem and going to address the situation.”
NHTSA complaint #10555835, filed 2013-12, 108,000 miles“The fuel tank strap broke while I was grocery shopping. I heard the tank rubbing against the drive shaft when I pulled out of my parking space. The vehicle is not drive able, and I believe this to be a serious issue.”
