THE DTE INDICATOR ON THE VEHICLE IS OPERATING INCORRECTLY. I FILLED THE HIGHLANDER UP WITH 10 MILES DTE AND IT ONLY TOOK 13.2 GALLONS OF FUEL. THE DTE INDICATOR WAS 425 MILES AFTER FILL UP. TOYOTA ADVERTISES 600 MILES PER TANK. MY HIGHLANDER IS 175 MILES OFF OF THE MANUFACTURES ADVERTISED EXPECTATION. I DON'T KNOW IF I AM OUT OF FUEL AT 0 DTE OR IF I CAN DRIVE ANOTHER 175 MILES BEFORE EMPTY. I AVERAGED 35.6 MPG ON THIS FILL UP BUT EVERY TIME I FILL THE TANK I GET SIMILAR RESULTS.
THE VEHICLE EV DOES NOT ENGAGE WHEN IT IS COLD OUTSIDE FOR AT LEAST 10-15 MINUTES OF DRIVING. THIS DRASTICALLY ALTERS THE FUEL ECONOMY.
THE 2021 HIGHLANDER HYBRID IS NOT TAKING MORE THAN 10-11GALLONS PER FILL UP AND THE DISTANCE TO EMPTY INDICATOR ONLY STATES APPROX. 420MILES NOT THE 590-615MILES BASED ON THE STATED 34/35 MPG PER TOYOTA ON THE HYBRID MODEL. WE HAVE FILLED THE VEHICLE SEVERAL TIMES AND AT MULTIPLE GAS STATIONS AND EACH TIME THE TANK WILL NOT ACCEPT MORE THAN 10-11GALLONS.
At random times, when traveling at 10-15 mph and applying the brakes to stop or slow, the brakes will slip for a second or less and then re-in-gauge. Never experienced this before with 2 other Toyota hybrids I have owned. Scary feeling. Have notified Toyota Customer service since I have read others with same model (highlander hybrid platinum) have same problem.
