2012 TOYOTA TUNDRA Engine Problems

AFTER STARTING THE ENGINE, THE ENGINE RAISED PAST RED LINE RPM FOR SEVERAL SECONDS. AFTER SLOWING, I STARTED TO BACK OUT DRIVE WHEN ENGINE RAISED AGAIN INTO RED LINE RPM. BEFORE I GOT IT PULLED BACK INTO DRIVE, IT RAISED 3 MORE TIMES. EACH TIME I MANAGED TO GET TO NEUTRAL.

ON 12/24/2012 AROUND 04:00HRS I STRUCK AN ADULT MOOSE IN BEAR LAKE, CANADA WITH THE FRONT END OF MY WIFE'S 2012 TOYOTA TUNDRA CREWMAX ON THE BRITISH COLUMBIA HIGHWAY. THE CONDITION OF THE ROAD WAS SNOW AND ICE BUT WE HAD RECENTLY PURCHASED AFTERMARKET RIMS AND TIRES ON 12/18/2012 IN CALIFORNIA; 18IN MB VOTEX RIMS WITH BFG ALL TERRAIN TIRES. THE TRACTION OF THESE TIRES BOOSTED MY CONFIDENCE IN TRAVELING AT SPEEDS OF 30-40MPH AT NIGHT. WE HAD TRAVELED ALL THE WAY FROM GEORGIA WITHOUT SEEING ANY ANIMALS AT NIGHT. THE HID HEAD LAMPS GAVE ME A FALSE SENSE OF SECURITY NAVIGATING THROUGH THE NIGHT IN ORDER TO MAKE THE FINAL LEG TO ANCHORAGE, AK FOR CHRISTMAS DAY. TO MY SURPRISE, A MOOSE TIPTOED FROM THE WOODS ON MY RIGHT ABOUT 20 FEET AHEAD OF ME AS I INTENDED TO PRESS ON PASS IT. BUT ALL OF A SUDDEN IT...

MY ISSUE IS RELATED TO THE ISSUE I AM FACING WITH TOYOTA COMPANY. I PURCHASED MY TRUCK WITHIN 2012 AND SINCE I HAVE PURCHASED THE TRUCK I TOOK THIS TRUCK TO THE DEALERSHIP FOR SEVERAL ISSUES.

I PURCHASED MY FLEX FUEL TUNDRA 5.7 IN NOVEMBER OF 2011. I STARTED TO EXPERIENCE ISSUES WITH COLD STARTS IN DECEMBER OF 2012. I HAD AN EXTENDED CRANK TIME, AND IT WOULD TAKE MULTIPLE ATTEMPTS TO START THE TRUCK. I TOOK IT TO THE DEALERSHIP FOR THE FIRST TIME IN JANUARY OF 2013. THE DEALERSHIP RESET MY COMPUTER. THE ISSUE SEEMS TO BE RESOLVED. THE FOLLOWING WINTER, IN DECEMBER OF 2013, I STARTED TO EXPERIENCE THE SAME ISSUE WITH COLD STARTS. THE DEALER APPARENTLY RESET MY COMPUTER AGAIN. JUST A MONTH LATER, JANUARY 2014, THE EXTENDED CRANK ON COLD STARTS BEGAN AGAIN. THIS TIME, THEY TOLD ME MY ALCOHOL DENSITY WAS READING 49%. THEY SAID IT SHOULD BE AT 85%, HOWEVER, I AM NOT USING STRAIGHT ETHANOL GAS, WHICH I TOLD THEM NUMEROUS TIMES, SO MY READING SHOULD NOT BE 85%. I WAS TOLD THE COMPUTER SHOULD RESET TO 0...

FLEX FUEL MODELS SOLD BY GULF STATES TOYOTA HAVE AN ISSUE WHERE THE ENGINE'S COMPUTER THINKS THERE IS E85 FUEL (OR AN ALCOHOL CONCENTRATION THAT IS MUCH HIGHER THAN ACTUAL) IN THE SYSTEM WHEN THERE IS NORMAL 10% OR LESS GASOLINE ACTUALLY PRESENT. THIS CAN CAUSE ROUGH COLD STARTS/IDLE, POWER LOSS, SUDDEN RPM/POWER DROPOUT, MISSING, AND LESSENED FUEL ECONOMY, ETC. (DIFFERENT SYMPTOMS FOR DIFFERENT TRUCKS). AT THIS TIME THERE IS NO FINAL FIX AND NO AVAILABLE SERVICE BULLETIN. THE ONLY GUIDANCE AT THIS TIME IS TO HAVE YOUR DEALER SEE WHAT ALCOHOL CONCENTRATION YOUR TRUCK IS RUNNING AND RE-FLASH THE COMPUTER IF THE READOUT IS INCORRECT. DEALER ALSO STATES TO NOT ACCELERATE AGGRESSIVELY. I HAVE SERVICE SCHEDULE ON 3/9/13 TO ADDRESS THE PROBLEM FOR THE THIRD TIME. I PURCHASED THE VEHICLE NEW ON 11/23/12. *TR

CHECK ENGINE LIGHT ILLUMINATED AS I DEPARTED MY DRIVEWAY. I CALLED TOYOTA SERVICE TO SCHEDULE AN APPOINTMENT WHICH OCCURRED THREE DAYS LATER. TOYOTA SERVICE DEPARTMENT DETERMINED THAT THE AIR PUMP, WHICH IS PART OF THE EMISSIONS SYSTEM, FAILED. I WAS ADVISED THE TRUCK COULD NOT BE DRIVEN. AS OF TODAY (12/17/12) THE PART HAS STILL NOT ARRIVED AT BOCH TOYOTA SOUTH. WILL THE DEFECTIVE AIR PUMP CAUSE PREMATURE FAILURE OF THE CATALYTIC CONVERTER? *TR
