Example complaints

“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 tacomas, tundras and sequoias. With certain years of tundras and sequioas, Toyota has paid for this fix. …”
NHTSA complaint #11384284, filed 2020-12, 71,196 miles“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.”
NHTSA complaint #11156727, filed 2018-12, 24,000 miles“My 4Runner is hard starting all the time. I’ve replaced the battery, tested the alternator etc. It sounds exactly like the problem of the fuel pump recall. The 4Runner was recalled from 2014-2015, my car was technically put together in Sept 2015, but is labeled a 2016. I believe my fuel pump is failing. I am extremely nervous it is going to not start one day while I am out camping.”
NHTSA complaint #11717449, filed 2026-02“Fuel pump failed , vehicle stalled driving 70 down highway.. I have read there is a Recall in place for 2014, 2015, 2017,2018 4 runners. Why not 2016?”
