1. The secondary air injection valve and/or air injection pump. 2. Sometimes the vehicle will go into "limp" mode and only go 35 mph. If the switch valve is stuck "closed" like mine, the car may not be able to dilute the exhaust fumes and the fumes and travel into the cabin of the vehicle. 3. Yes, check engine light code was read as P2441. 4. No, the vehicle can not be driven at this time. 5. No, and around July 24th the check engine light came on. The symptoms continued to get worse. In short, Toyota has issued extended warranties and reimbursements for this design flaw for Tunda's 2007-2010. The design flaw being the air pumps allow water and debris to be sent into the air injection valves. My truck being a 2011 was never alerted to this issue or covered due to the year of my vehicle. The issue is my truck is the SAME generation truck as the 2007-2010 trucks. Which means I too have the design flaw as well but Toyota is refusing to fix their mistakes. After further inspection of my truck, see attached pictures, there is obvious water in the valve system and it has been rusted as well (unable to clean it). My issue is Toyota only covering half of the generational years for a design flaw that is also in the other half. These repairs can range from $2k-$4k and it seems as Toyota only made the extension to the most relevant truck years at the time and left everyone else behind. It is very distributing that a large manufacturer would cut corners like this, for a flaw that was their design.

While driving the check engine light came on and I lost propulsion power resulting in vehicle slowing down and almost creating an accident from behind.
