Toyota Sienna abs comes on

Filed Nov 17, 2025 · Brakes, Electrical · MD

Vehicle: 2011 Toyota Sienna XLE VIN: [XXX] Mileage: ~204,800 Incident Date: [XXX] Recent Service: Oil change, tire rotation, brake inspection, and multipoint inspection performed on November 10, 2025 at Fitzgerald Toyota Gaithersburg (Maryland). Description of the Defect: On [XXX] while driving with my child in the vehicle, my 2011 Toyota Sienna experienced a sudden and dangerous failure. A strong burning smell entered the cabin, the ABS warning light illuminated, and then wheels locked up while the vehicle was in motion. At the same time, the steering wheel locked, making the vehicle impossible to steer. The engine immediately lost power and shut down in the middle of the roadway. The vehicle would not restart and had to be towed. This failure occurred four days after dealership service at Fitzgerald Toyota Gaithersburg, which included an oil change, tire rotation, and brake inspection. The dealership initially claimed the failure was due to a “dead battery,” and the following day changed the explanation to a “shorted alternator.” A weak battery or alternator failure does not explain a mechanical wheel lock or steering wheel lock while driving. The dealership has refused to provide diagnostic documentation or photographs of the components involved. This incident presents a significant safety hazard, and if it had occurred at highway speeds, it could have resulted in a severe crash. I am reporting this to request investigation into a potential safety defect involving the steering system, braking/ABS system, electrical system, or related components. Safety Risk: High. Loss of steering control + wheel lock + engine shutdown presents an immediate crash hazard. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Catalizador causando bajas emisiones, consecuencia encendido de codigos de luz de advertencia de tablero como luz indicadora de falla (check engine). Luz de advertencia ABS. Luz indicadora de derrape vsc-trac y luz de advertencia de presion de neumaticos. Al viajar por carretera simplemente se apago y sin poder tener control de la misma dicha falla causo que ya no encendiera al tener que solicitar grua para el arrarstre de la unidad hasta la agencia de toyota en cordoba veracruz. Seguro solo intervino con el arrastre de la unidad. Pero la sienna a llevado hasta el dia de hoy y fecha presente todos los servicios de agencia por la cual se llevo de inmediato, pero con la novedad es que ni la misma agencia le a podido quitar la falla. No tienen ni la menor idea de la causa. Su solucion seguen ellos eran los inyectores pero la camioneta volivio a hacer la misma falla y la agencia no da garantia de su mano de obra. Solo aumenta el gasto en refacciones sin solucionar la falla.

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!!!!!!!!

This has happened multiple times. Driving at various speeds. Sometimes driving straight other times turning. ABS activates with out cause. ESC light illuminates. Happens when in traffic causing the van to try to stop in traffic without warning. Thus far mechanic has not been able to duplicate.

Bought the van used last year. Previous owner said mechanic could not diagnose the issue. On slight curves similar to on-ramps while accelerating the Vehicle stability control (VSC) will engage unexpectedly, sound an alarm and jerk the steering wheel. Some times to the point of pulling the vehicle out of its lane. Road speed is decreased dramatically as it feels as though the ABS is engaging. This has happened to me at least half a dozen times since June 2023. The condition will continue for maybe five or ten seconds until the wheel is straightened and speed reduced. Searching the Internet seems it's a fairly common problem. The fix might be to replace the steering rack or disable the VSC system. It's reported by those experiencing the issue get little to no help from the dealerships which strikes me as quite strange... From what I've read it seems to affect 2004-2009 Siennas

The contact owns a 2020 Toyota Sienna. The contact stated while driving approximately 15 MPH and making a turn, the brake pedal was depressed, and the vehicle skidded. The ABS warning light was illuminated. There was an abnormal sound coming from the vehicle. The vehicle was taken to the local dealer, where it was diagnosed that there was a speed sensor short circuit on the front passenger’s side, and that the brake actuator was fractured. The vehicle was not repaired due to parts not being available. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 28,000. The VIN was not available.

The slip indicator light and alarm comes on sporadically, engaging the ABS suddenly and unexpectedly, when we are on completely dry roads. Happens while driving 40-80 mph. And doesn’t matter if I’m going straight or turning.

I was driving on a dry road, going 70mph when my car began flashing the abs indicator and it began breaking and controlling my steering taking me into another lane. The car slowed my vehicle suddenly down to 60 mph and then went off like it never happened. I then had control. There was no reason for the car to do this. There was nothing in the road and luckily no one was to close to me or there would have been an accident. I almost over corrected due to the pulling of the steering and the breaking of the vehicle.

Every time I go around a curve, the ABS TRC and vehicle beeps like I'm sliding. It happens on every curve. Its very dangerous. I have unplugged the sensor under the front passenger seat and all problems go away. i have replaced this part and it still has not fixed the problem. with part unplugged i have no ABS TRC Airbags none of the safety equipment is working while unplugged, but is safer than having my brakes slammed in every curve.

- Traction control engaged at high speed(70 mph on interstate) causing the vehicle to brake abruptly and pull the vehicle to the right. Had I been traveling in the left hand lane, I could have been forced into the right hand lane causing a collusion with another vehicle. Also occurred at lower speed(30 mph on a windy road) causing the same issue as described above, almost causing the vehicle to leave the paved surface. - Mechanic was able to duplicate the issue - Mechanic diagnosed intermittent traction control activation, scanned computer for codes. Yaw rate/steering angle correlation causing false activation ABS/traction. Replaced hub bearing and spindle. Four wheel alignment, including check castor, camber and adjust toe. Performed zero point calibration and reset ABS memory. - Traction control lights up briefly
