2015 TOYOTA HIGHLANDER Service Brakes Problems

I have noticed speed issues or high idling with this vehicle for a while. I committed a rear end collision with a vehicle on July 4, 2025, at approximately 2pm. My car rear ended his truck while it was stopped behind another vehicle. My vehicle sustained total damage to the front end. I was ticketed for not reducing speed to prevent a accident. The only warning light was that it need maintenance, which comes on prior to an oil change. My safety was put at risk because the car is idled too fast for the type of driving I do, which is small town and rural road driving. Due to the speed of this vehicle during normal driving, it's difficult to stop quickly to avoid an accident. If it was rainy and slippery, the situation could have been much worse.

The following error message appears:“Both accelerator and brake pads are depressed”. This is not actually being done.The vehicle will then brake suddenly on its own, and the driver must accelerate then brake quickly to disengage the automatic brake.This creates a highly dangerous traffic situation. It has occurred at high speeds on the expressway and makes merging into traffic especially risky.Vehicle has been inspected on 4 occasions by Toyota dealerships and they have failed to diagnose or repair the problem, simply stating that the problem "needs to go to corporate" and taking no further action. Issue has been reported to Toyota Nat'l Service Center and am now awaiting resolution with the regional service engineer.

WHEN THE CAR HAD 20K MILES THE BRAKES WOULD SHAKE WHEN GOING DOWN HILL, TOOK IT IN BUT THEY FOUND NOTHING WRONG. I HAVE SINCE HAD THE ROTARS TURNED BRAKES REPLACED AND WHEN BRAKING THE BRAKES SHAKE REALLY BAD ITS SCARY. I HAVE ALSO HAD TOO MANY ELECTRICAL PROBLEMS WITH THE DOOR LOCKS ONE GOES OUT THEN NEXT WEEK ANOTHER, THE OUTLETS HAVE NEVER WORKED AND NOW THE STEREO IS GOING TO BE REPLACED BECAUSE IT BLACKS OUT AND RESTARTS CONSTANTLY.

ON 10/30/16 I TOOK MY 2015 HIGHLANDER TO A LOCAL TOYOTA DEALER FOR WARPED ROTORS. THEY AGREED THE ROTORS WERE WARPED AND SINCE IT WAS AT 35,000 MILES THEY REPLACED ALL 4 ROTORS UNDER WARRANTY PLUS 2 NEW BRAKE PADS WHICH I HAD TO PAY FOR. I NOTICED THE SAME ISSUE IN LATE MAY OF 2017 AND CALLED TO ASK ABOUT THIS. THEY SAID "WE DON'T WARRANTY WARRANTY WORK" AND SUGGESTED I CALLED TOYOTA HEADQUARTERS. ON JUNE 21, 2017 I CALLED TOYOTA AND FILED A COMPLAINT. I WAS TOLD TO TAKE THE CAR TO A DIFFERENT LOCAL DEALER, CLOSER TO MY HOME, AND THEY WOULD INSPECT THE ROTORS FOR A CHARGE. ON JULY 11, 2017 I DID THIS AND THE SERVICE REP TOLD ME SHE NOTICED THAT THE ROTORS WERE "BLUE" AND SHE NOTED THAT THEY SHOULD BE CHANGED. THE SERVICE MANAGER CALLED TOYOTA HEADQUARTERS WITH THIS INFO BUT THEY REFUSED TO COVER THIS, STATING THAT THIS WAS NORMAL WEAR AND TEAR. LATER THAT DAY I HEARD FROM THE TOYOTA HQ REP WHO REPEATED THAT TOYOTA COULD NOT COVER THIS. ON 8/7/2017 I FILED A COMPLAINT WITH VERMONT ATTORNEY GENERAL'S OFFICE. AS OF 10/10/17 THIS COMPLAINT IS STILL NOT RESOLVED AS THEY WON'T COVER THE REPAIR. THE CAR IS NOW AT 63,000. THIS IS A SAFETY ISSUE. NOTE: ACCORDING TO TOYOTA NATION WEBSITE MANY OTHERS HAVE HAD THESE SAME ISSUES. BELOW IS THE RESPONSE FROM THE DEALER ON AUGUST 24, 2017. I DISCUSSED THIS SITUATION WITH OUR ASSISTANT SERVICE MANAGER. SHE DID CONTACT TOYOTA TO ASK THEM TO COVER THIS REPAIR AND THEY DECLINED. THEIR REASONING FOR THIS IS THAT THE CONDITION OF THE BRAKE ROTORS, I.E. THEY ARE BLUE, INDICATES A HEAT EVENT. THIS USUALLY RESULTS FROM HEAVY BRAKING, BRAKING WHILE GOING DOWNHILL OFTEN OR SOMETIMES IF THE BRAKES GOT HOT AND THEN WENT THROUGH COOL WATER. IF YOU WOULD LIKE TO ADDRESS THIS WITH TOYOTA FURTHER, I ENCOURAGE YOU TO REACH OUT TO THE TOYOTA CUSTOMER EXPERIENCE CENTER AT 800-331-4331 OR VIA EMAIL USING THIS FORM. . .

WE WERE DRIVING DURING HEAVY RAINS AT FREEWAY SPEEDS. TRAFFIC WAS SLOWED AHEAD. THE SYSTEM SIGNALS AN ALARM THAT TRAFFIC AHEAD IS SLOWING, A VERY NICE FEATURE. HOWEVER, WHILE THE ALARM WAS GOING OFF, I DEPRESSED THE BRAKE PEDAL WITH ZERO RESPONSE, LIKELY DUE TO THE ABS NOT WANTING ME TO SLIDE ON THE WET ROADS. HOWEVER AS I GOT CLOSER AND CLOSER TO THE SLOWED TRAFFIC AHEAD, I NEEDED TO PRESS THE BRAKE HARDER AND HARDER. THE BRAKES SIMPLY STOPPED DECELERATING THE HIGHLANDER AND WE SMASHED INTO THE BACK OF A SMALLER VEHICLE. WHILE I APPRECIATE ABS AND THE DESIRE TO PREVENT SLIDING, I MUST BE ABLE TO STOP MY VEHICLE. I HAVE READ COUNTLESS COMPLAINTS ABOUT THIS OCCURRING, YET I DO NOT SEE A RESOLUTION.

HAD A PROBLEM WITH A 13 MO. OLD HIGHLANDER(STILL UNDER WARRANTY). WAS BACKING INTO MY GARAGE WHEN THE BRAKE PEDAL SUDDENLY BROKE(RUBBER PIECE FELL OFF). IT CAUSED MY FOOT TO SLIP OFF THE BRAKE AND CONSEQUENTLY BACKED INTO A REFRIGERATOR WE HAD IN THE GARAGE. IT RUINED THE REFRIGERATOR AND DAMAGED THE BACK OF THE HIGHLANDER($1000+) WORTH OF DAMAGE. FILED A CLAIM WITH TOYOTA(CORPORATE) AND COOPERATED FULLY WITH THEIR INVESTIGATION. AFTER 4 MOS. OF GETTING NOTHING BUT A RUN AROUND FROM TOYOTA FINALLY GOT THEIR ANSWER TO THE PROBLEM. THEY SAID THE VEHICLE WAS FINE(WHY THEN DID THE BRAKE PEDAL FALL APART?) AND THAT THEY DIDN'T CARE AT ALL ABOUT MY PROBLEM. THEY ALSO DIDN'T ANSWER WHY THE BRAKE PEDAL FELL APART IF 'ALL WAS FINE' AS THEY ASSERTED. KIND OF LIKE WHAT TOYOTA DID 6 OR 7 YEARS AGO WHEN THE ACCELERATOR PROBLEM FIRST SHOWED UP. BACK THEN THEIR FIRST REACTION WAS TO BLAME TH VICTIMS(OWNERS) FOR CAUSING THE PROBLEM!! I SUGGEST TO OTHERS TO NOT BUY A TOYOTA. AS MY PROBLEM SHOWS, IF AN UNUSUAL PROBLEM HAPPENS THEY WILL NOT STAND BEHIND THEIR VEHICLE OR DESIGN!!

DRIVING FORWARD INTO PARKING SPACE. JUST ABOUT STOPPED. PRESSED BREAK. CAR LURCHED FORWARD AT HIGHT SPEED SUDDENLY, CAUSING CAR TO JUMP CURB AT TOP OF PARKING SPOT AND CAREEN DOWN HILL (ONTO SIDE WALK). CAR OUT OF CONTROL FOR ABOUT 2 SECONDS. WAS ABLE TO BREAK IN HILL, WHICH PREVENTED ME FROM HITTING CAR PARKED PERPENDICULAR ON STREET BELOW. BOTTOM OF CAR SCRAPED CURB WHEN CAR JUMP CURB AND LURCHED FORWARD. BOTTOM FRONT BUMPER SCRAPED. THERE WAS AN ICY PATCH AT TOP OF PARKING SPACE. IT SEEMS LIKE WHEN WHEELS ROLLED ON TOP OF ICY PATCH, THE CAR LURCHED FORWARD. CAR MIGHT HAVE ACCIDENTALLY BEEN ON CRUISE CONTROL AT THE TIME.

WHILE THE VEHICLE WAS BEING DRIVEN, THE POWER CUT OUT AND A MESSAGE APPEARED ON THE DASH STATING THAT THE BRAKE AND ACCELERATOR WERE BEING DEPRESSED SIMULTANEOUSLY -- BUT THEY WERE NOT. THIS HAPPENED THREE TIMES IN A ROW. WE HAD THE VEHICLE TOWARD TO THE TOYOTA DEALER WHERE PURCHASED. THEY COULD NOT FIGURE OUT WHAT WAS WRONG AND ATTRIBUTED THE PROBLEM TO "DRIVER ERROR." THE DEALER'S MECHANIC PRODUCED A REPORT INDICATING THAT SIMILAR MALFUNCTIONS HAD OCCURRED IN THE PRIOR TWO MONTHS WITH NO NOTICE TO THE DRIVER. TOYOTA COULD PROVIDE NO EXPLANATION FOR THIS. TOYOTA CLAIMS THAT NOTHING IS WRONG AND REFUSES TO REPAIR OR REPLACE THE VEHICLE.

POPPING SOUND COMING FROM RIGHT FRONT SIDE WHEN BREAKING TO A STOP AT ALL SPEEDS. THE PROBLEM WAS FIRST NOTICED AT AROUND 2500 MILES AND THE CAR WAS TAKEN TO THE DEALER AT AROUND 2900 MILES. DEALER INSPECTED IT AND COULDN'T FIND WHAT THE PROBLEM WAS. THEN AS INSTRUCTED BY TOYOTA REPLACED THE RIGHT FRONT STRUT ASSEMBLY BUT THAT DIDN'T FIX THE PROBLEM. THE CAR WAS RETURNED TO ME AND I WAS TOLD THERE WERE NO SAFETY CONCERNS AND THAT TOYOTA WAS SENDING ONE OF THEIR TECHS TO TROUBLESHOOT, BUT THAT MAY TAKE A COUPLE OF WEEKS. IN THE MEAN TIME THE PROBLEM SEEMS TO BE GETTING WORSE.

CLUNKING NOISE FROM REAR END OF VEHICLE WHEN BRAKING, DEALER WAS AUTHORIZED TO CHANGE REAR AWAY BARS AND SHOCKS, NO FIX, NOW TOYOTA CORP., SAYS THIS IS NORMAL CHARACTERISTIC OF VEHICLE ? I DON'T FEEL SAFE DRIVING VEHICLE WITH NOISE, AND AS BRAKES FEEL SOFT ALSO.
