| May 2019 | SERVICE BRAKES | THE PRE-COLLISION SYSTEM FAILED TO ASSIST IN AVOIDING AN ACCIDENT WHEN THE CAR IN FRONT OF ME STOPPED SUDDENLY IN TRAFFIC ON A HIGHWAY. SINCE THE REPAIR, THE BRAKE WARNING INDICATOR LIGHT ON THE SPEEDOMETER SIDE OF THE INSTRUMENT CLUSTER INTERMITTENTLY ILLUMINATES AND THE BRAKE PEDAL PULSES AS IF THE ABS SYSTEM IS ENGAGING. ONCE IT STOPPED ME SUDDENLY WHILE DRIVING DOWN A BUSY CITY STREET. WENT FROM 35 TO 0 VERY SUDDENLY. I HAVE TAKEN THIS TO 2 DEALERS AND THEY SAY THERE IS NOTHING WRONG. THE SYSTEM DOES NOT INDICATE AN ERROR EVEN THOUGH THE LIGHT IS ON AND THEY TESTED WHILE IT WAS ON. I CAN RECREATE THE ISSUE BY ACCELERATING QUICKLY WHILE TURNING LEFT. SOMETIMES IT HAPPENS WHEN GOING STRAIGHT, BUT THE ONLY WAY TO GUARANTEE IT WILL HAPPEN IS TO TURN AND ACCELERATE QUICKLY. NEITHER OF THE 2 DEALERS I HAVE TAKEN IT TO HAVE FOUND THE ISSUE AND TOYOTA CUSTOMER CARE STOPPED CALLING ME BACK. | Crash: Yes Fire: No Towed | 16,000 |

THE CAR HAD BEEN LOCKED FOR SEVERAL HOURS, BUT WHEN I CAME OUTSIDE I WAS TOLD BY A FRIEND THAT THE HATCH HAD JUST OPENED ON IT'S OWN. ABOUT AN HOUR LATER, I WAS DRIVING AFTER DARK AND RECEIVED A BLINDSIDE MIRROR ALERT--THE CLOSEST CAR WAS AT LEAST TWO CAR LENGTHS IMMEDIATELY BEHIND ME IN THE SAME LANE. SHORTLY AFTER, THE CAUTION LIGHT CAME ON, BEEPED, THE ECO LIGHT CAME ON, IT BEEPED AGAIN AND THE ECO LIGHT WENT OFF. ABOUT 40 MINUTES LATER, I HAD THE BRIGHT HEADLIGHTS ON WITH THE AUTO DIM ENACTED. THE HEADLIGHTS WENT OUT, THE DASH LIGHTS WENT OUT, THE RADIO STAYED ON, AND THE NAVIGATION SCREEN GOT VERY BRIGHT. I HAD TO RETURN THE LIGHT CONTROL ON THE SIGNAL SWITCH AWAY FROM THE SETTING AND THEN BACK TO GET THE HEADLIGHTS AND DASH LIGHT TO COME BACK ON. ALL EVENTS EXCEPT HATCH WERE WHEN VEHICLE IN MOTION. HATCH OPENED WHILE PARKED AND EMPTY. ALL EVENTS WERE WITHIN APPROXIMATELY 2 HOURS OF EACH OTHER. 10000 MILE SERVICE HAD JUST BEEN COMPLETED 3/15/19 WITH NO CONCERNS NOTED. | Crash: No Fire: No | 11,500 |
| Mar 2019 | SEATS | THE XLE FRONT PASSENGER SEAT SITS VERY HIGH, CAUSING MY HEAD TO BRUSH UP AGAINST THE CEILING. THIS IS WILL CAUSE HEAD AND POSSIBLY NECK INJURIES IN THE EVENT OF A COLLISION. I'M NOT PARTICULARLY TALL AT 5'10', BUT ANYONE TALLER WILL HAVE A WORSE PROBLEM. THERE IS NO WAY TO LOWER THIS SEAT. I DON'T WANT TO SUFFER A HEAD INJURY JUST BECAUSE THE SEAT IS VERY HIGH. | Crash: No Fire: No | Unknown |
| Mar 2019 | ELECTRICAL SYSTEM | DEAR SIR. UNIT CAN NOT BE CHANGED. THE UNIT CAN NOT BE CHANGED FROM F TO ℃. I HAVE BEEN LIVING IN CELSIUS TEMPERATURE ENVIRONMENT FOR MORE THAN 50 YEARS AND HAVE RECENTLY EMIGRATED TO THE UNITED STATES. BY THE WAY, MY CAR CAN NOT SEE THE CELSIUS TEMPERATURE. SO, I HAVE TO CALCULATE THE FAHRENHEIT TEMPERATURE IN DEGREES CELSIUS FOR A SHORT TIME EACH TIME TO KNOW THE CURRENT CELSIUS TEMPERATURE. (CALCULATED SIMILARLY TO CELSIUS TEMPERATURE = (FAHRENHEIT - 30) / 2) I CAN NOT CONCENTRATE ON DRIVING WHILE CALCULATING THE CELSIUS TEMPERATURE, AND I HAVE TO CONCENTRATE ON THE CALCULATION. (DURING THE SHORT TIME) I KNOW THAT A CAR ACCIDENT HAPPENS IN A VERY SHORT TIME. I WAS REGULARLY CHECKED AT A TOYOTA DEALERSHIP TODAY. (5,000 MILES FREE SERVICE) I CAN NOT CHANGE THE UNIT TO CELSIUS TEMPERATURE WHEN I START REGULAR INSPECTION. I ASKED YOU TO CHECK. AFTER COMPLETING THE REGULAR CHECK, THE SERVICE CONSULTANT ANSWERED ME "I CAN NOT CHANGE TO CELSIUS." SO, I ASKED AGAIN WHY NOT. A SERVICE CONSULTANT REPLIED, "A CAR PRODUCED IN THE UNITED STATES RECENTLY HAS NO CHANGE IN CELSIUS." SO, I AM WRITING THIS ARTICLE. THE TOYOTA SERVICE CONSULTANT SAYS THAT THE 2018 TOYOTA HIGHLANDER, PRODUCED IN THE UNITED STATES, IS UNCHANGED IN UNITS OF CELSIUS. PLEASE MAKE SURE THAT NEW CARS PRODUCED IN THE FUTURE CAN BE CHANGED IN UNITS OF CELSIUS TEMPERATURE. (FOR REFERENCE, THE UNITS ARE CHANGED FROM 'MILE' TO 'KM'.) I WOULD LIKE TO RECEIVE A REPLY BY EMAIL THANK YOU, SIR. *TR | Crash: No Fire: No | Unknown |
| Mar 2019 | EXTERIOR LIGHTING | THE HEADLIGHTS ARE REALLY DIM MAKING IT DIFFICULT TO SEE AT NIGHT. WHEN I AM NEXT TO OTHER VEHICLES, THEIR HEADLIGHTS LIGHT UP THE ROAD IN FRONT OF ME AT LEAST 80% MORE THAN MY HEADLIGHTS. PHYSICALLY, THE HOUSING LOOKS DEFECTIVE BECAUSE IT IS CLOUDY. PERHAPS A RECALL SHOULD BE ISSUED. I HAVE HAD THE CAR SINCE MAY 2018 BUT NEVER DROVE DURING NIGHT / DARK HOURS UNTIL MY SHIFT RECENTLY CHANGED. | Crash: No Fire: No | 4,000 |
| Mar 2019 | WHEELS,UNKNOWN OR OTHER,SERVICE BRAKES | CAR VIBRATION AT 40MPH AND UP AND BRAKE VIBRATION TOO . | Crash: No Fire: No | 300 |

| Feb 2019 | UNKNOWN OR OTHER | AFTER CAR HAS BEEN DRIVEN, IS OFF AND SITTING IN LOCKED GARAGE AFTER ABOUT 2 HOURS A LOUD BUZZING SOUND CAN BE HEARD WHICH EVENTUALLY CHANGES TO A LOW SEMI BUZZING (ALMOST LIKE A COMPUTER DOWNLOADING AND A FAN TO COOL IT DOWN). I'VE CONTACTED THE SERVICE DEPARTMENT AND LEFT A DETAILED MESSAGE, BUT NO RESPONSE. I'M AWARE OF CYBER SECURITY, AND SINCE MY HUSBAND WORKS FOR DOE (WAPA), IT WORRIES ME. MY HUSBAND ALTERNATES WEEKLY ON DRIVING THE HIGHLANDER OR THE 2000 TACOMA. WHEN HE DOESN'T DRIVE THE HIGHLANDER THERE IS NO NOISE, WHEN HE DOES THE BUZZING SOUND HAPPENS. THIS IS TOO COINCIDENTAL. IS THIS NORMAL? THE SOUND APPEARS LOUDEST BY THE RIGHT REAR WHEEL WELL. IT NORMALLY HAPPENS AFTER 11:00 P.M. AND COMPLETES BEFORE 11:30 P.M., HOWEVER, OVER THE PAST 4 DAYS THE SCHEDULE HAS CHANGED. TONIGHT IT RAN FROM 8:00 P.M. TO 8:35 P.M. WHAT IS GOING ON WITH OUR NEW VEHICLE? IS IT SAFE FOR MY HUSBAND TO DRIVE? | Crash: No Fire: No | Unknown |
