My truck has been having hard start issues since winter 2017. I figured it was my battery so i replaced it, but it didnt help.

My 2012 tundra has just under 70,000 miles on it and the trac light and engine light came on yesterday.

While driving, multiple dashboard lights came on and my truck went into "limp mode," meaning i lost almost all power while driving in heavy traffic.

I experienced an extreme power loss which made it very dangerous to drive. When bringing to the dealership they informed me that the secondary air intake system needed to be replaced at a cost of $4,000. Upon researching i found that this problem has occurred on similar vehicles dating back to 2007. A recall and replacement was issued for all effected vehicles from 2007-2010. It appears that the problem continues…
