Secondary air injection pump has high rate of failure, recalls in older models. Has caused truck to go into limp mode. Could cause serious accident/fatality if vehicle suddenly goes into limp mode on highway. This has happened on multiple occasions in forums I-??ve read. Known problem by Toyota that isn-??t being addressed.

2012 Toyota Tundra has a known design flaw in that moisture is allowed to condense, accumulate and corrode in components of the secondary air intake system leading to decrease performance especially in regards to acceleration which is critical to operating a vehicle safely.

Check engine light went on. Got a code P0418-vehicle will go limp/not able to go over 25mps. Toyota has a warranty repair program in place for all 2012 Tundra with a 5.7 size but not mine because it is a 4.6 even though it is the exact same problem!!!

Please refer to tsb 0160-11. Toyota recognized that inferior quality parts were used as part of their emissions system and wrote this tsb as a remedy. The problem I have is that they continued to use the faulty parts beyond the 2011 model year cut-off in this tsb. My truck is throwing the same engine and emissions codes associated with this tsb. It also forces the engine into a "low power mode" greatly reducing the ability to accelerate. Lastly, it turns off traction control which affects the stability of the truck. I have filed a ticket with Toyota and from what I have read on the internet, I don't expect much help. The parts to repair this run over $1,000 alone. There are many owners having the same issue with the Tundra, sequoia and some other models (on the 4.6L, 4.7L and 5.7L engines). The engine codes usually appear on startup (when the emissions device are supposed to kick in), but the low power mode kicks in while moving.

After only a few months of owning the truck almost every morning when I try to start the truck it took at least 2 cranking cycles to start. It's been a on going thing and now the throttle acts up when I first pull out of the driveway. It doesn't give any code and the dealership can't figure it out. The truck now has 36322 miles on it.
