2016 Toyota 4runner Fuel System Problems

Your 4Runner is having trouble starting consistently, even though you've already replaced the battery and tested the alternator. The starting problem sounds similar to a fuel pump issue from a recall that affected 2014-2015 models, and since your 2016 was built in September 2015, it may be affected. A failing fuel pump could eventually leave you stranded, so having it inspected and replaced if necessary should resolve the starting issue.

Your fuel pump failed while you were driving 70 mph on the highway, causing your vehicle to stall. You've noted that Toyota has issued recalls for fuel pump problems on 2014, 2015, 2017, and 2018 4Runners, but not for 2016 models. Replacing the fuel pump will be necessary to restore normal operation.

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. WHY NOT THE 4RUNNERS AND TACOMAS??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.
