The Toyota secondary air system has failed rendering my car without traction control... and other lights. There is no preventative measures for this part and Toyota used the exact same system on the Tundra's and sequoia's with the same problem I'm having. This needs to be addressed as the repair for the system is roughly $4000 almost half the cost of my car... please make them fix this on all cars where the same system was used.

My check engine light came on along with vsc trac. After taking vehicle to dealership I was told that the repair would cost $2,048.73 due to the air pump being stuck in off position. While Toyota in response to reports of air induction pump assemblies and/or air injection switching valves issues on their 2007-2010 Tundra and 2008-2010 sequoia models, Toyota has decided to increase its warranty on these parts and is even offering a reimbursement if you already had this issue fixed. My vehicle has the identical engine of the above-named vehicles but Toyota does not offer any help with the 4runner. It is my understanding that if I do not get the problem fixed it becomes a huge problem within federally mandated emissions requirement.
