Electrical system

7 reports1 related recall
“The contact owns a 2018 Toyota Sequoia. The contact stated while driving at 55 mph, the lane departure and rear cross passing warning light illuminated and the vehicle failed to turn off. The contact took the vehicle to the local dealer to inspect the vehicle however, the mechanic was unable to duplicate the failure. Several months later, the failure recurred. The contact took the vehicle back to the same local dealer to be inspected. The contact was informed that the rear bumper sensor was not properly aligned to the brackets on the bumper, causing the failure. The vehicle was repaired however, the contact was concerned that at some point the failure might recur. The manufacturer was made aware of the failure. The failure mileage was 45,000.”

Fuel/propulsion system

2 reports
“I own a 2018 Toyota Sequoia experiencing fuel pump failure symptoms including extended crank and loss of power. This issue matches NHTSA Recall 20V012000, which affects similar vehicles with the same fuel pump defect. However, my VIN is not included in the recall despite identical symptoms and safety risk. I am requesting investigation into whether additional VINs, including mine, should be included in this recall due to ongoing failures.”

Lane departure

2 reports
“In the past few months the automatic braking feature was activated without any reason. No obstruction in front, no unusual weather or driving conditions. Fortunately nobody was close behind and no accident occurred. Today the blind spot and cross traffic indicators stopped working. I have not taken it into the dealer yet. I will do so soon.”

Service brakes

2 reports
“I AM HAVING A RECURRENT PROBLEM WITH MY 2018 SEQUOIA IN THAT I AM CONSISTENTLY GETTING WARNING LIGHTS AND ALARMS GOING OFF FOR 'BRAKE WARNING,' REAR CROSS TRAFFIC ALERT, 'BLIND SPOT MONITOR MALFUNCTION' AND 'FRONT CAMERA MALFUNCTION.' IT HAS BEEN IN THE SHOP 5 TIMES AND THEY KEEP SAYING THERE ARE COMPUTER GLICHES AND KEEPNUPDATING THE SOFTWARE OVER AND OVER AGAIN. TOYOTA SENT DOWN A TECH FROM DENVER TO TAKE A LOOK AT IT AND INSTEAD OF REPAIRING THE PROBLEM, THEY HAVE DISARMED ALL OF MY ALARMS BECAUSE WHAT THEY SAID WAS THAT THEY WERE SET TOO SENSITIVE?! THIS IS A HUGE SAFETY ISSUE AS TWO OF THE TIMES THAT THE 'BRAKE WARNING' FLASHES THE TRUCK STARTS TO SLOW ITSELF DOWN. WHAT IF THIS HAPPENS WHEN AN 18-WHEELERBIS BEHIND ME? THE BRAKE LIGHTS DON'T COME ON TO LET THEM KNOW THAT MY VEHICLE IS SLOWING DOWN!! I AM VERY SCARED OF DRIVING THIS VEHICLE AND TOYOTA SAYS IT'S SAFE TO DRIVE? I'M AT A LOSS AS WHAT TO DO NOW GIVEN THAT ALL OF THESE SOFTWARE UPDATES ARE BEING DONE AND ALARMS ARE DISABLED I FEEL LIKE I'M DRIVING IN A VEHICLE THAT IS UNSAFE!!”
