2015 Toyota Sienna: ABS light or ABS activating

Filed Apr 2, 2025 · Brakes, Driver assistance · NC

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.

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.

While driving on the nys thruway with the cruise control activated my van came to an abrupt stop on the thruway. There were no vehicles in close proximity to my van that would have activated the radar cruise or the autonomous emergency braking system. After the abrupt stop all the lights on the dash were lit up ie: brake, ABS, pcs, slip indicator light, and master warning light. When I reached my destination I was unable to open the doors of my vehicle. Someone tried to open the doors from the outside of the vehicle and they were unable to open them as well. I brought it to the local toyota dealer and they could find nothing wrong. The above lights have lit up on several occasions however the dealer could find nothing wrong. There has been a previous complaint for the same behavior on 6/6/15 reported to toyota for the same make and model as mine a toyota sienna premium and they have not been able to get toyota to act on it.
