In owners' own words
With only 81,719 miles on my truck I had to have the air injection pump & valves replaced on 3/29/2019. I was informed that this was a common problem which had been recalled in the 2011 & 2010 models.
My tundra with 75,000 miles has a camshaft tower leak and this oil is falling into the exhaust manifold without being noticed because it doesn't make it to the floor, but it gets to the sensors and starts ruining them.
My 2012 tundra with 107k displayed the check engine, 4LO, and traction control warning lights and would only drive in 'limp mode'.

These vehicles were sold with labels that were outside the allowable one percent of accuracy of actual weight added. An inaccurate label could lead to owners overloading their vehicles and tires. An overloaded vehicle can result in a tire failure which may result in a vehicle crash, personal injury, or property damage.
During modification by SET to include accessories such as leather seat covers, seat heaters or headrest DVD systems, these vehicles may not have had the passenger seat occupant sensing system calibration tested. Without passing the calibration test, the occupant sensing system may not operate as designed. If the front passenger seat occupant sensing system is out of calibration, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position.
