What owners wrote
June 1st 2021 I went to park in a parking space at a local mall. My truck instead of stopping it accelerated out of control jumped two stone curbs, drove though a fence and landed into a swamp. Call Toyota and they have opened a new case # 210602000065. Police report # 21-374-AC. This isn't the first time that this has happen with this truck. It happen in Aug 2019. I contacted Toyota case number 1908060035. They sent out EAA Engineering Analysis Ass. out who did a ACM.CDRX file a month later.
Failure of the secondary air injection pump and valve emission system prompted engine to run in a reduced power mode, and this occurred on a on a relatively new vehicle with below average mileage. While setting may protect engine, this created an unsafe driving environment for vehicle within fast moving traffic. My compliant is not related to the reduced driving mode that may have protected the engine, but rather the poor design of the air-pump/valve system that prematurely failed causing the reduced power mode.
