Open the full vehicle complaint log (all categories)I PURCHASED A BRAND NEW 2012 TOYOTA SEQUOIA. SINCE I BOUGHT THE VEHICLE, THE VEHICLE HAS HAD IDLE/ACCELERATOR PROBLEMS, ERRATIC PROBLEMS WITH EXCESSIVE TRANSMISSION DOWNSHIFTING, RACING, SURGING, AND FLUCTUATION OF ENGINE RPM'S, MAKING THE VEHICLE DIFFICULT TO STOP SAFELY. WHEN I FIRST PURCHASED THE VEHICLE, THE SERVICE DEPARTMENT EXPLAINED TO ME THAT IT WAS A NEW VEHICLE AND IT NEEDED TIME,??ONE THOUSAND MILES,?? FOR THE ENGINE TO BREAK IN. THEIR INITIAL SOLUTION TO MY VEHICLE'??S PROBLEM DID NOT RECTIFY ITSELF. I HAVE HAD TO RETURN IT TO THE DEALERSHIP 2 TIMES FOR REPAIR. THEY STATED THAT THEY HAVE CONFIRMED MY CONCERNS WITH THE VEHICLE BUT IT COULD NOT BE REPAIRED. THAT IT IS A DESIGN CHARACTERISTIC OF THE VEHICLE, THAT'S THE WAY THEY ACT, AND THAT IT HAD SOMETHING TO DO WITH FUEL-CUTTING OR TRANSMISSION SHIFTING. HE FURTHER STATED THAT HE FORWARDS HIS REPORT TO TOYOTA ENGINEERS AND IF THERE ARE ENOUGH COMPLAINTS THAT THEY WILL RE-WRITE AND UPDATE THE SOFTWARE FOR THE VEHICLE. OBLIVIOUSLY A SAFETY ISSUE...PLEASE ADVISE. *TR
