2009 Toyota Tundra Transmission Problems

While driving at 35 mph, your engine suddenly revved up and the truck slowed down unexpectedly. When you pressed the brake pedal, the vehicle accelerated instead of stopping. The dealer found that the driveshaft assembly had failed and replaced it. The fix involved replacing the driveshaft assembly.

Your truck has been making a dragging noise from the front drivetrain since around 12,000 miles, and the dealer couldn't locate the source during two inspection visits. The noise has gradually worsened over 46,000 miles and now includes vibrations on the highway. This repair will likely require front drivetrain component inspection and possible replacement of worn or damaged parts.

I WAS THE OPERATOR OF THE VEHICLE ON MY DRIVEWAY WHEN THE ENGINE SUDDENLY ACCELERATED. THE ACCELERATOR WAS WIDE OPEN WHILE I WAS HARD ON THE BRAKES. I WAS ABLE TO PUT THE GEAR SHIFT INTO PARK, AND ONCE I DID THE ENGINE STOPPED ITS ACCELERATION. I WAS ON HARD CONCRETE, THUS THE REAR WHEELS SPUN FREELY WITHOUT CATCHING TRACTION. THE VEHICLE LEFT ROUGHLY 30" OF FRONT AND REAR WHEEL MARKS. THE VEHICLE HAS RUN NORMALLY SINCE THE INCIDENT. *TR

TRUCK GETS A BUMP AFTER COMING TO A STOP. SOMETIMES IT'S GETS A REALLY HARD BUMP AND SOMETIMES IT'S JUST A LITTLE BUMP. I KEPT THINKING I GOT HIT AS IT IS VERY NOTICEABLE. NO ONE SEEMS TO KNOW WHY, BUT I DO KNOW THIS, IT ONLY HAPPENS WHEN THE A/C IS RUNNING. I BELIEVE IT'S A COMPUTER SOFTWARE PROBLEM. IT TOOK A COUPLE OF YEARS BECAUSE I FOUND OUT IT ONLY HAPPENS WHEN THE WEATHER GETS WARM AND I USE THE A/C. SEEMS LIKE QUITE A FEW PEOPLE ARE HAVING THE SAME PROBLEM AND THE DEALER IS SAYING "I DON'T KNOW ANYTHING" BECAUSE THEY CAN'T DUPLICATE THE PROBLEM, HOWEVER I SEEM TO BE ABLE TO DUPLICATE IT ALL THE TIME. *JS

I HAVE A 2009 TOYOTA TUNDRA WITH THE 5.7L ENGINE AND 6 SPEED AUTO TRANSMISSION. INTERMITTENT SHIFTING OCCURS AS SLOW SPEEDS, WITH THE VEHICLE ACTING LIKE THE TRANSMISSION IS IN NEUTRAL. THIS HAS CAUSED SERIOUS CONCERN WHEN TRYING TO ACCELERATE AND COULD LEAD TO A POTENTIAL ACCIDENT. I HAVE ALSO HAD THIS OCCUR ON SLICK SURFACES, WITH THE ENGINE REVVING UP BEFORE THE TRANSMISSION ENGAGES. THIS HAS CAUSED EXTREME TIRE SLIPPAGE AND RISK OF LOSING CONTROL. I HAVE HAD THIS TRUCK INTO THE DEALERSHIP THREE TIMES AND HAVE HAD THEIR QUALITY TEAM LOOK AT IT, WITH NO SATISFACTORY RESOLUTION. OTHER OWNERS OF TUNDRAS ARE ALSO REPORTING THIS SAME PHENOMENA, AND CONCERNS, WITH NO RESOLUTION FROM TOYOTA. WE ALL NEED YOUR HELP TO GET CORRECTIVE ACTION PUT IN PLACE. AN ACCIDENT IS WAITING TO HAPPEN, IF IT ALREADY HASN'T. *TR
