NHTSA Complaint #11360380 — 2017 TOYOTA HIGHLANDER

ON 3 SEPARATE OCCASIONS AT 30,000, 40,000 AND 42,000 MILES WHEN DRIVING AT INTERSTATE HIGHWAY SPEEDS (AROUND 70 MPH) WITH CRUISE CONTROL ENGAGED, THE VEHICLE HAS SUDDENLY WITHOUT WARNING SWITCHED TO A LOW POWER LIMP HOME MODE RESULTING IN RAPID DECELERATION IN THE MIDST OF HIGH SPEED HIGHWAY TRAFFIC. I BELIEVE THIS IS A VERY DANGEROUS SITUATION. MULTIPLE WARNINGS APPEARED ON THE DASH INCLUDING LOW POWER MODE, CHECK AWD SYSTEM, AND SEE YOUR DEALER. SHUTTING OFF THE VEHICLE AND RESTARTING IT ALLOWED THE VEHICLE TO BE DRIVEN NORMALLY AGAIN. AFTER ALL THREE INCIDENTS THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSIS. ALL 3 TIMES THE COMPUTER HAD STORED CODES FOR RANDOM MULTIPLE MISFIRES ALONG WITH A FEW OTHERS. ALL THREE TIMES THE DEALER INDICATED THAT THE CODES DID NOT POINT TO A SPECIFIC FAULTY PART THAT THEY COULD REPLACE, SO THERE WAS NOTHING THEY COULD DO. AT MY INSISTENCE THAT SOMETHING BE DONE AFTER THE THIRD INCIDENT THE DEALER OPENED A CASE WITH THE TOYOTA TAS SYSTEM TO ASK FOR ASSISTANCE IN DIAGNOSES. THE ONLY RESULT OF THIS WAS TO SWITCH SOME OF THE COIL PACK POSITIONS TO SEE IF THE MISFIRES FOLLOWED THE COIL PACK. THE END RESULT IS THAT I HAVE TO DRIVE IT UNTIL IT FAILS AGAIN, PUTTING MYSELF AND OTHERS AT RISK. I ALSO OPENED A CASE WITH THE TOYOTA CUSTOMER EXPERIENCE CENTER, THEY CONFIRMED THIS WAS ALL TOYOTA WOULD DO AT THIS POINT.
