NHTSA Complaint #10717042 — 2015 TOYOTA HIGHLANDER

THE DASH READOUT FOR MPH BEGAN SHOWING VERY ERRATIC NMBERS. GOING FROM 24.4 MPG TO 29.7 MPG AND DOWN TO 13.1 MPG ALL IN A SPAN OF ABOUT 4 MILES. THIS MPG OF 24.4 WAS FOR THE PRIOR 3000 MILES. THE DEALER COULD NOT REPLICATE THIS HAPPENING. THEY ALSO SAID THAT TOYOTA HAD NO BULLETINS FOR THIS MATTER EITHER. I CONTACTED TOYOTA AND THEY SAID THAT I MUST HAVE ACCIDENTALLY RESET THE UNIT AND BY DOING SO IT WAS NOT UNUSUAL FOR THESE LARGE SWINGS IN MPG. THIS WAS NOT THE CASE. I HAD OVER 100 MILES ON SINCE MY LAST FILL UP AND UNTIL THIS HAPPENING THE MPG NUMBER WAS QUITE STEADY. THE ONLY THAT I INDEED MAY HAVE DONE THIS WAS THAT LAST FILL UP BECAUSE THAT IS THE ONLY TIME THAT I EVER DO A RESET AND I DID NOT DO IT AT THAT TIME. PREVIOUSLY I HAD SEEN SOME STRANGE SWINGS IN MPG BUT NOT AS LARGE OF A SWING AND NOT LASTING FOR AS LONG OF TIME AND THOSE INSTANCES THE READING DID SELF CORRECT.
