“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 4000.00 almost half the cost of my car... Please make them fix this on all cars where the same system was used.”
