2015 Toyota Sienna

I have had this car for 7 years. Started having issues a year ago and despite bringing it to Toyota 2x, they cannot tell me what the issue is. I will be driving on a regular flat paved road when the car will suddenly brake and pull me towards the side of the road. I get the ABS code sometimes and also the slip indicator light. I've explained this each x I've brought it in and they have told me it's due to me "driving too fast" or "accidentally having my foot on the brake." LOL I am a typical soccer mom and drive conservatively and don't brake when I don't have to. It will do it on curving roads as well as straight roads. When this happens, it is terrifying! I have gone to different mechanics as well and no one can determine this issue. I've replaced the ABS sensors on this and am still having this issue. I don't know what else to do, as this is unsafe and unsafe to the extent that I no longer allow my 17 year old to drive it. Please help!!!!!!!!

When I drive this van downhill on a curve not fast slower than 40mph, the antilock brakes engage violently and hard and jerky I do not have my foot on the brake when this happens. I'm not going fast. But the ABS is so violent it causes me to lose control of the steering. It happened 3 times in 24 hours and always in same situation. Only lasts a few seconds. Other Sienna owners have had same issues. 119k miles on the van. Bought it used. Had no idea. Of course dealership can't replicate the problem and won't help us. I'm scared to drive the car.

DRIVING 35-55 MPH AND GOING AROUND (USUALLY) A LEFT CURVE ON THE HIGHWAY OR INTERSTATE, VAN SUDDENLY BRAKES, SWERVES, AND TRACTION CONTROL/VEHICLE STABILITY CONTROL LIGHT POPS ON. WHOLE EPISODE LASTS A SECOND OR TWO, THEN ITS FINE. IT WONT HAPPEN AGAIN FOR THE DURATION OF THE TRIP. I ONLY DRIVE THE VAN ON WEEKENDS, AND IT HAS HAPPENED THREE TIMES IN THE PAST TWO WEEKS. IT HAS NEARLY CAUSED A SERIOUS ACCIDENT.

BRAKE SHAKING/SHUTTER UPON BRAKING DOWN A STEEP HILL. THE 2015 SIENNA AWD HAS 45,000 MILES. THE SIENNA HAS MOSTLY BEEN DRIVEN ON FLAT TO MILD SLOPED INTERSTATE ROADS THAT DO NOT REQUIRE BRAKING. RECENT INSPECTION BY A TIRE SHOP REPORTS 12/32 REMAINING ON BRAKE PADS SHOWING MINIMAL TO NO WEAR. UPON DRIVING DOWN A STEEP ROAD REQUIRING BRAKING TO CONTROL SPEED THERE WAS VIOLENT SHAKING/SHUTTER IN THE FRONT END. THINKING SOMETHING WAS BROKEN, REDUCED THE SPEED AND USED TRANSMISSION TO CONTROL SPEED TO REDUCE BRAKE APPLICATION. THIS RELIEVED THE VIOLENT SHAKING. CHECKING INTERNET THERE IS A TOYOTA TSB FOR THIS PROBLEM REPLACING BRAKE PADS AND ADDITIONAL WORK. THE PROBLEM HAS TO BE REPORTED TO TOYOTA WITHIN THE 36,000 MILE WARRANTY TO HAVE THE PROBLEM FIXED BY TOYOTA. THIS PROBLEM NEEDS TO BE FIXED BY A SAFETY RECALL WHEN OEM REMAIN ON THE VEHICLE.

THE VEHICLE WAS STATIONARY AND ONE DAY ABS MALFUNCTION LIGHT CAME ON DUE TO FAULTY HARNESS ON A 3 YEAR OLD 35,000 MILE VEHICLE. THIS REDUCES THE ABILITY OF THE VEHICLE TO STOP NORMALLY AS IT SHOULD THIS ALSO DISABLES THE TRACTION CONTROL ON THE VEHICLE. I WAS DRIVING IN RAIN WITHOUT ANY TRACTION CONTROL AND IT WAS SCARY. I CONTACTED TOYOTA AND THEY KEEP STATING THE CAR IS OUT OF WARRANTY. IT IS $500+ REPAIR TO ABS SYSTEM DUE TO THEIR FAULTY PARTS. I JUST NEED THIS TO BE ON THE RECORD INCASE SOMETHING HAPPENS WHILE DRIVING A TOYOTA SIENNA.

VAN WOULD REBOOT WHILE PARKED OR DRIVING. IT STARTED WITH DASHBOARD REBOOTING THEN I COULDN'T START THE VAN. THERE WAS A TIME AFTER DRIVING I PUT THE VAN IN PARK AND TURNED IT OFF BUT MY VAN WAS MOVING ON IT'S OWN. I ALWAYS CALL THE DEALERSHIP WHEN THE REBOOTING OCCURS. I WAS TOLD EITHER IT WAS A SOFTWARE ISSUE OR SINCE THE PROBLEM WENT AWAY, I SHOULD BE FINE. WELL RECENTLY WHEN MY VAN STALLED AND HAD TO BE TOWED TO THE DEALERSHIP. I WAS TOLD IT WAS A BATTERY ISSUE AND THE BATTERY WAS REPLACED. WHEN I PICKED UP MY VAN AND WENT HOME, NOTICED MY REAR VIEW CAMERA WOULD NOT COME ON WENT I PUT THE VAN IN REVERSE. CALLED THE DEALERSHIP TO TELL THEM WHAT'S GOING ON AND THE SERVICE ADVISOR WOMAN WAS VERY RUDE AND STATED IT WAS BATTERY AND THEY NEVER CHECKED ANYTHING ELSE. I STATED TO THE WOMAN THE I'VE ALWAYS EXPRESSED MY CONCERNS ABOUT THE VAN REBOOTING, WON'T START, OR MOVING ON IT'S OWN. THE WOMAN BECAME VERY RUDE AND HUNG UP ON ME. I DECIDED TO GO RIGHT BACK TO THE DEALERSHIP ON THE WAY THERE I CALLED BACK TO SPEAK TO THE MANAGER OF SERVICE DEPARTMENT TO EXPLAIN WHAT'S GOING ON. WHILE DRIVING THERE THE CHECK ENGINE AND ANOTHER LIGHT TURNED ON. SHORTLY AFTER THAT AS I WAS TURNING LEFT, WHILE IN THE MIDDLE OF THE INTERSECTION MY VAN STALLED. THE STEERING WHEEL AND BRAKES LOCKED AND THE VAN COMPLETELY SHUTS OFF. I WAS LOCKED IN MY VAN WITH NO CONTROL OVER THE VAN AND IT WAS MOVING TOWARDS A POLE. LUCKILY THE VAN STOPPED BEFORE HITTING ANYONE OR ANYTHING. I WAS ON THE PHONE WITH THE SERVICE MANAGER THE ENTIRE TIME. THE MANAGER CALLED FOR SOMEONE TO PICK ME UP AND CALLED A TOW COMPANY. I ASKED THE MANGER IF THEY ARE STATING MY ISSUE WAS A BATTERY AND A NEW BATTERY WAS INSTALLED WHY AM I STILL HAVING THE SAME ISSUE. THE POLICE WAS CALL BECAUSE SOMEONE REPORTED MY VAN IN THE MIDDLE OF THE INTERSECTION.

TL* THE CONTACT OWNS A 2015 TOYOTA SIENNA. WHILE DRIVING AT AN UNKNOWN SPEED AND MAKING A LEFT TURN, THE BRAKE PEDAL WAS DEPRESSED, BUT FAILED TO RESPOND AS IT TRAVELED TO THE FLOORBOARD. AS A RESULT, ANOTHER VEHICLE CRASHED INTO THE FRONT PASSENGER CORNER PANEL OF THE CONTACT'S VEHICLE. THE CONTACT AND A PASSENGER IN THE OTHER VEHICLE SUSTAINED UNKNOWN INJURIES THAT REQUIRED MEDICAL ATTENTION. THE AIR BAGS DEPLOYED. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC. THE LOCAL DEALER AND MANUFACTURER WERE NOT CONTACTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS 32,774. THE VIN WAS NOT AVAILABLE.
