Driving last week and check engine light along with traction control light came on. Hooked my OB2 scanner to port but came up with no codes. Drove it a few more days and eventually lights went out. Fast forward a week and lights came back on. Same routine with the OB2 but this time the code P2443 came up. Googled it and " secondary air injection system switching valve stuck closed bank 2". found out there is a huge history with this problem not only with my 4runner but with Tacoma, Tundra and sequoias. With certain years of Tundra and sequioas, Toyota has paid for this fix. Why not the 4runners and Tacoma??same problem!! this whole thing is a big sham. It will cost about $2000 plus for this issue to be fixed. Where I come from, this is robbery. Knowingly selling vehicles with a expensive problem and not recalling them to be fixed.

Massive fuel leak from the soy-based fuel lines. Allegedly an animal chewed thru them which was attracted by the soy-based product (rather than the petroleum based lines of the past) I have great fear that the incident will repeat itself. Fuel lines sprayed out about 8-10 gallons of fuel during 30 minutes while driving.
