NHTSA Complaint #10157402 — 2006 TOYOTA TUNDRA

THURSDAY 5/11/06 IDLE UPON START UP GOES TO 2000 RPM, AND STAYS THERE FOR APPROXIMATELY 1-1 1/2 MINUTES, BEFORE SLOWING DROPPING DOWN TO AROUND 1500 RPM. IT SEEMED TO REALLY BE STRAINING AGAINST THE BRAKE, WHEN I PUT IT INTO DRIVE, AGAIN, NOT THE FEEL IT HAD WHEN IT WAS BRAND NEW. FRIDAY 5/12/06 IT NOT ONLY HAD THE HIGH IDLE, BUT WHILE DRIVING AT HIGHWAY SPEEDS SEEMED TO HAVE A RANDOM SURGE WHILE DRIVING. COULDN'T DETECT A PATTERN TO IT, WHETHER ON INCLINE, DECLINE, OR FLAT ROADWAY. UPON ARRIVING AT WORK, I PLACED THE TRANSMISSION INTO PARK, AND IDLE WAS APPROXIMATELY 750 RPM (BY DASH TACH) WHEN SUDDENLY IT RACED UP TO 1500 RPM, STAY THERE FOR ABOUT 30 - 45 SECONDS, THEN RETURNED TO 750 RPM. THIS SURGE SITUATION CERTAINLY PRESENTS A POSSIBLE SAFETY PROBLEM, IF THE SURGE WAS TO OVERRIDE THE BRAKE PRESSURE AND LURCH FORWARD AT STOP, OR IN BUMPER TO BUMPER TRAFFIC. *JB
