2012 TOYOTA TUNDRA with 137000. miles

Check engine light with error code P2433 0160-11 failure of air injection pumps i was getting on the highway, the engine light comes on, then the truck goes into "limp mode." the lane i was in merged to the left. I needed to accelerate to avoid a vehicle coming up on my left, but there was no power due to being in "limp mode." the vehicle coming up behind me had to slam on his brakes and i swerved off the shoulder. This could have been a very bad accident if there was a concrete barrier in front of me. This is a known malfunction and should be a recall item. Toyota has publically said this is a warrantable repair up to 150,000 miles on 2011 model year Tundras. I have the exact same problem on my 2012 (which was built in 2011) but Toyota is not willing to cover the repair. I will now be out of pocket $3400 if i want to keep driving my truck.

2006 SUBARU WRX with 66870.0 miles

Code P1410 secondary air injection system switching valve stuck open. This is a common error many 2006 and up Subaru impreza Wrx owners are having. The emissions system is prone to fail due to carbon buildup or moisture and rust contaminating valves, leading to repairs costing $700 to $1500. This failure is common even with low mileage. Note these codes are also associated with this failure: 06/07 Wrx: P0410 P0411 P0413 P0414 P0416 P0417 P0418 P2431 P2432 P2433 P2440 P2441 P2442 P2443 P2444 07 sti: P0410 P0411 P0413 P0414 P0418 P2431 P2432 P2433 P2441 P2444
