“In august 2014, transmission went out and stalled while we were traveling at a high rate of speed on the interstate. We could have been run over and smashed to death had we been in a one lane construction zone. We purchased the car new in 2011 and the car had only 63,000 miles. We took our car regularly to the dealer for maintenance and had never been warned of any transmission issues and no transmission issues presented themselves untilthe day it stalled on the interstate. Toyota said we needed a new transmission. We had to pay $1000 out of pocket.”

NHTSA complaint #10817348, filed 2016-01, 63,000 miles

“Driving on interstate at about 70 MPH with cruise control on. Vehicle suddenly began to decelerate down to 20mph. Could not get vehicle to accelerate using the gas pedal. Finally came to a complete stop. After several minutes of the slow speed (3 to 5 minutes) then the complete stop switched the cruise control off and was able to slowly accelerate again. Vehicle maintained 1500 to 2000 rpms the entire time of the incident. The engine did not race nor did it stall. No warning lights came on. …”
