At 70000 miles and around 9/1/2023, started to notice our brake stop suddenly steep down pedal when braking at 45mph or higher. Problem starts after fuel pump replacement recall completed by dealership August 2023. Check recall and campaign program, my vehicle VIN specifically not on the recall list for brake booster vacuum pump. I thinks Toyota HQ should take my vehicle into consideration since my vehicle is a 2017 Sienna. Contact HQ they refused to offer to diagnosis nor help replace if applicable. Due to your vin not on the recall, your on your expense.
When going down a parking ramp exit, my foot has slipped off the brake 3 time. When looking at the brake pedal it is smaller than most brake pedals. I don't know if anyone else has had this problem, but mandating a minimal size for brake pedal might help
I have a 2017 Toyota Sienna that has needed the braked replaced on average every 6 months and I have already replaced the roaters 4x. This car eats brakes and roaters.
THE VACUUM BRAKE ASSIST FAILED WITH LESS THAN SLIGHTLY LESS THAN 50K MILES ON THE CAR. NOT SURE EXACTLY WHEN IT FAILED BECAUSE THE BRAKE AND TRACTION CONTROL LIGHTS WERE ON INTERMITTENTLY FOR AWHILE BEFORE WE TOOK THE CAR IN FOR SERVICE. WE DID HAVE A NEAR MISS WHILE MAKING A LONG DRIVE WHEN WE WERE TRYING TO LEAVE THE INTERSTATE ON AN OFF RAMP AND I WAS ALMOST UNABLE TO STOP AT THE TOP OF THE RAMP. I HAD TO ANGLE THE VEHICLE TO THE LEFT TO AVOID HITTING A PICKUP TRUCK AT THE TOP OF THE RAMP.
