2004 Toyota Highlander Electronic Stability Control Esc Problems

Your Vehicle Stability Control (VSC) system has activated unexpectedly while driving, causing the car to brake on its own and pull to the right, making it difficult to control. This happened once in 2005 (resolved after a steering angle sensor calibration at the dealer) and again in 2016, where the VSC light came on at highway speeds and the car braked by itself multiple times. The issue is concerning because it could cause a loss of control, especially at higher speeds. A repair will likely involve diagnosing and recalibrating or replacing the steering angle sensor, VSC control module, or related brake components.

Your vehicle's stability control system (VSC) is activating unexpectedly while driving at normal speeds on dry pavement. When you exceed 8-10 mph, the VSC warning light comes on and your car automatically applies the brakes, making it nearly impossible to drive. You're also hearing a loud scraping sound during these events. This problem likely needs a scan of your vehicle's stability control sensors and brake system to identify what's triggering the false activation.

Your traction control system is turning on by itself while you're driving normally on regular roads. This shouldn't happen during normal driving conditions and suggests the system may be malfunctioning or a sensor could be dirty or failing.

SUMMARY: ON DEC. 30, 2009, I EXPERIENCED A MALFUNCTION IN THE ELECTRONIC STABILITY CONTROL SYSTEM OF MY 2004 4CYL FWD TOYOTA HIGHLANDER SUV. THE MALFUNCTION IS EXACTLY OF THE NATURE DESCRIBED IN THE SUMMARY OF FINDINGS FOLLOWING AN ODI INVESTIGATION OF MALFUNCTIONS IN THE ELECTRONIC STABILITY CONTROL SYSTEMS OF 2003 TOYOTA SEQUOIA VEHICLES(NHTSA CAMPAIGN ID NUMBER 10V176000, NHTSA ACTION NUMBER EA09006). COMPLAINT: THE MALFUNCTION IN MY HIGHLANDER OCCURRED WHEN THE VEHICLE STARTED FORWARD AT VERY LOW SPEED AFTER HAVING BEEN BACKED OUT OF A PARKING SPACE. THE VEHICLE SUBSEQUENTLY HESITATED AND SURGED DURING ACCELERATION AND THE BRAKES WERE AUTOMATICALLY APPLIED AND RELEASED AS IF THE VEHICLE WERE EXPERIENCING A SKID. UNLIKE THE COMPLAINTS CONSIDERED IN THE ODI INVESTIGATION, HOWEVER, THE MALFUNCTION IN MY HIGHLANDER DID NOT SELF-CORRECT. THE VEHICLE WAS SERVICED THE FOLLOWING DAY AT ACTON TOYOTA IN LITTLETON, MA, WHERE THE MALFUNCTION WAS CORRECTED BY RESETTING THE ON-BOARD COMPUTER. THE VEHICLE OPERATED NORMALLY AFTER THE COMPUTER WAS RESET. SINCE ACTON TOYOTA WAS UNABLE TO IDENTIFY A CAUSE FOR THE MALFUNCTION IN THE ELECTRONIC STABILITY CONTROL SYSTEM, I HAD THEM REPLACE THE STEERING ANGLE SENSOR AS A PRECAUTIION ON JANUARY 6, 2010. ACTION: BASED UPON MY EXPERIENCE, I THINK THAT A RECALL OF 2004 4CYL FWD HIGHLANDERS SIMILAR TO THAT FOR 2003 SEQUOIAS SHOULD BE UNDERTAKEN.

TL*THE CONTACT OWNS A 2004 TOYOTA HIGHLANDER. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 50 MPH, THE VEHICLE BEGAN TO SWAY OUT OF CONTROL FROM LEFT TO RIGHT. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALERSHIP FOR DIAGNOSIS WHERE THE CONTACT WAS ADVISED TO REDUCE SPEED TO 35 MPH TO GAIN CONTROL OF STABILITY. THE DEALER ALSO STATED THAT THE STABILITY CONTROL MODULE COMPUTER WAS OFF BALANCE AND NEEDED TO BE REPLACED. THE ELECTRONIC STABILITY CONTROL FAILED AGAIN IN 2008. THE VEHICLE HAD NOT BEEN REPAIRED AT THE TIME OF THE COMPLAINT. THE VIN WAS UNAVAILABLE WHEN THE COMPLAINT WAS FILED. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 9,000.

I AM THE OWNER OF A 2004 TOYOTA HIGHLANDER 2WD. THIS VEHICLE IS IN EXCELLENT CONDITION, LOW MILEAGE (ABOUT 40,000) AND HAS NEVER BEEN IN AN ACCIDENT. ON APRIL 19, THE VEHICLE STABILITY CONTROL/ANTI-SLIP BUZZER SOUNDED. THE ICON LIT ON THE DASHBOARD, AND THE VEHICLE STARTED TO BREAK AS IF THE CAR WAS SLIPPING. THE ROAD WAS DRY, OUR SPEED WAS EXTREMELY LOW (ABOUT 15MPH), AND THERE WAS NO REASON FOR THIS TO HAPPEN. THANKFULLY, WE WERE JUST OUT OF OUR DRIVEWAY AND COULD TURN SAFELY AROUND THOUGH THE PROBLEM PERSISTED. ON APRIL 20TH, WE PHONED TOYOTA OF KEENE TO MAKE AN APPOINTMENT TO BRING IN OUR VEHICLE. WE WEREN'T THRILLED WITH THE PROSPECT OF DRIVING UNDER THESE CONDITIONS, BUT FIGURED IF WE KEPT TO LOW SPEEDS WE SHOULD BE ABLE TO MAKE IT SAFELY. WE TOOK DOWN THE TOW COMPANY'S NUMBER JUST IN CASE. ON APRIL 21ST, MY HUSBAND SET OUT FOR THE APPOINTMENT FOR REPAIR IN KEENE. ABOUT 10 MILES FROM HOME, THE PROBLEM SUDDENLY WENT AWAY. THE SKID WARNING LIGHT WENT OUT AND THE VEHICLE STOPPED BREAKING AUTOMATICALLY. MY HUSBAND MADE IT THE REST OF THE WAY TO TOYOTA OF KEENE WITHOUT ANY ISSUES. AFTER A TEST DRIVE, THE TECHNICIAN STATED, 'THAT WAS THE SCARIEST TEST I'VE EVER EXPERIENCED,' AS THE PROBLEM HAD RETURNED WHILE HE WAS ON THE ROAD. BUT BY THE TIME HE RETURNED TO THE SHOP AND HOOKED UP THE CAR TO DIAGNOSTIC COMPUTERS, THE PROBLEM HAD AGAIN CEASED. TOYOTA OF KEENE HAS HAD MY VEHICLE SINCE APRIL 21ST, AND HAS BEEN UNABLE TO REPAIR IT OR OFFER ANY SOLUTION TO THIS ISSUE. THEY CLAIM THAT THEY CAN'T REPAIR IT IF THEY CAN'T REPLICATE THE PROBLEM WHILE THE VEHICLE IS HOOKED UP TO COMPUTERS. THOUGH I UNDERSTAND THIS EXPLANATION, IT DOES NOTHING FOR THE SAFETY OF MY FAMILY, AS WELL AS ANYONE ELSE ON THE ROAD. I CONTACTED THE TOYOTA COMPLAINT CENTER AND THEY OPENED UP A CASE NUMBER BUT WERE ESSENTIALLY USELESS IN ASSISTING ME. I DID SOME RESEARCH ON LINE AND FOUND A TECHNICAL SERVICE BULLETIN AS WELL AS CUSTOMER COMPLAINTS ABOUT THIS VERY ISSUE. *TR

TL*THE CONTACT OWNS A 2004 TOYOTA HIGHLANDER. WHILE DRIVING 5 MPH, THE CONTACT EXPERIENCED UNWANTED TRACTION CONTROL ACTIVITY, WHICH CAUSED THE VEHICLE TO BRAKE EXCESSIVELY. HE TOOK THE VEHICLE TO A LOCAL REPAIR SHOP AND THE MECHANIC REPROGRAMMED THE PCM MEMORY, WHICH REMEDIED THE FAILURE. THE DEALER COULD NOT DETERMINE THE CAUSE OF THE FAILURE. CURRENTLY, THE FAILURE HAS NOT RESURFACED. THE FAILURE MILEAGE WAS 49,450. UPDATED 01-26-09 *BF UPDATED 01/27/09. *JB

TL*THE CONTACT OWNS A 2004 TOYOTA HIGHLANDER. WHILE DRIVING 40 MPH, THE VEHICLE STABILITY SYSTEM ACTIVATED ON DRY SURFACE AND ATTEMPTED TO STEER THE VEHICLE. THE FAILURE AFFECTS THE STEERING AND OCCURS EVERY FEW FEET. SINCE THAT TIME, THE SYSTEM ATTEMPTS TO ACTIVATE AUTOMATICALLY WHILE DRIVING 15-20 MPH. THE VEHICLE STABILITY SYSTEM ACTIVATES AT FULL SPEED WHEN DRIVING AT HIGHWAY SPEEDS. THE DEALER STATED THAT THE FAILURE WAS IN THE MICROTRIP THAT CONTROLS THE VEHICLE STABILITY SYSTEM. THE DEALER IS CURRENTLY ATTEMPTING TO HAVE IT REPROGRAMMED. THE PURCHASE DATE WAS UNKNOWN. THE CURRENT AND FAILURE MILEAGES WERE 39,000.
