2020 Toyota Highlander brakes problems

Filed Oct 19, 2026 · Brakes, Driver assistance · CA

Thanks for your service, which is much appreciated. I had a terrifying experience with my 2020 Toyota Hylander Hybrid on XXX. I was traveling slowly on the right Eastbound lane of [XXX] trying to exit onto [XXX], when a car suddey merged from my left, near my front bumper. I put on my brakes with enough room to spare to avoid a collision, however the Hylander overrode my controls, slammed on the brakes with a squeal of my tires, stopped my car completely, started doing a slow, repeating beep, and wouldn't move, though the engine was running. This left my husband and I in an active freeway lane with cars traveling in front of us, to the side of us, and coming up behind us, at 65-70 mph., unable to move our vehicle. I had to turn off the engine off and on again, while in the active freeway lane, to get the Hylander to stop beeping and get it to move again so I could drive off the freeway. I was terrified we'd be rear-ended and possibly be killed, since some automated system in the Hylander would not allow the car to move after it took over and slammed on the brakes. I contacted Stevens Creek Toyota in [XXX] soon afterwards hoping to speak with a service manager about what happened. [XXX] I was told that no one was available when I described my issue to a phone receptionist there. She sent me to a manager's voicemail, where I left a detailed message about what happened. I asked that I be called back as soon as possible, to disable whatever feature caused the car to react in such a dangerous way. No one from the dealer ever called me back or offered a solution. I have no idea what to do or where to go, to get this feature disabled, or if it can hopefully be disabled. Please investigate why 2020 Toyota Hylander Hybrids have a feature that takes over the controls, slams on the brakes, then doesn't allow the car to move again until the car is completely turned off and on again.

Incident: [XXX] Conditions: Clear daylight, dry pavement, normal highway conditions Crash/Injuries: Allstate Claim #[XXX]; several people injured At approximately [XXX], I was driving my 2020 Toyota Highlander Hybrid at about 55 mph in the slow/right lane. The vehicle ahead suddenly made a hard stop. I immediately and forcefully applied the brakes for an emergency stop. My front-seat passenger, [XXX], also saw the danger and yelled for me to stop at the same time. Based on our recollection, approximately five seconds elapsed between his warning and the collision. Despite the rapidly closing distance, the Toyota Pre-Collision System (PCS) did not appear to activate. There was no audible warning/beeping, no flashing red warning, and no “BRAKE!” indicator on the dashboard. This was also observed by [XXX] and [XXX], who was seated in the second row and is particularly attentive to warning signals. The vehicle also did not appear to provide any automatic emergency braking or brake-assist intervention. Despite my immediate and forceful braking, the vehicle did not stop in time and collided with the vehicle ahead, causing significant damage and injuries. The forward-facing sensors and windshield were clean and unobstructed. There were no dashboard warning lights or known system malfunction indicators before the crash. I purchased the Toyota Plus service package after completing the required maintenance during the initial coverage period. All scheduled maintenance and inspections were performed on time by certified Toyota technicians. I was repeatedly assured that the vehicle, including the braking system, was operating normally. I request that the federal safety agency investigate the possible failure of the PCS, forward collision warning, automatic emergency braking/brake assist, and their integration with the braking system.

Coming to a stop or slowing down the vehicle has a spot where it feels like the brakes fail then come back on. Especially if going down a grade. This happens around 15 to 20 mph. Started off a slight moment when you are sure the brakes quit working for just a second. As the vehicle gets older it has brown to be more noticeable.

I was told by oxmoor dealership I had to talk to toyota corporate before I could get my car touched and that I did not need to talk to a lawyer. I called. Prior to the accident, the vehicle had been exhibiting multiple symptoms: an intermittent airbag warning light had illuminated briefly on the dashboard on a few occasions, and the vehicle had begun requiring noticeably longer physical distances to come to a complete stop at traffic signs and lights when not using cruise control. The vehicle was experiencing regular phantom seatbelt warnings—dinging as if a passenger was unbuckled when the seat was completely empty. The phantom seatbelt warnings i didnt think we're a big deal were occurring across multiple seating rows simultaneously in front and back. Directly preceding the crash, while making a turn, the vehicle swerved slightly. When I applied the physical brake pedal, the vehicle did not decelerate normally; instead, it experienced a sudden, abrupt forward acceleration surge into the building. I still haven't gotten my vehicle back or any information on what has been done or when I am getting my car back. I was also charged for an extra day for my rental when I was told to return it on the 16th. I haven't had a rental since then. I keep contacting oxmoor toyota and they said they were waiting on toyota corporate. I haven't had my car for a month. I tried to email. It was returned. My mailbox on my phone has been full of drs and other calls non stop. I texted online on the toyota page for the claim as well. Ive repeatedly asked the toyota dealership what is going on and I get we are waiting on corporate. I called toyota corporate again today and was told they would get back to me. I told the dealership. I am under medical care and in severe pain. Yes my safety was put at risk. Police and fire department were here the night it happened. They said they don't do a police report on private property. There is an insurance claim through state farm.

I am submitting this complaint regarding a serious braking safety issue with my 2020 Toyota Highlander Hybrid Limited, which currently has approximately 70,000 miles. I brought my vehicle to Victory Toyota of Canton (46352 Michigan Ave, Canton, MI 48188) and reported to Service Manager John Maddison that, at low speeds, the vehicle briefly surges or feels as though it accelerates when I press the brake pedal before it actually begins to slow down. This behavior is alarming and creates the impression that the vehicle is moving forward when I am attempting to stop. This is a serious safety concern that could increase the risk of a crash, particularly in parking lots, stop-and-go traffic, or around pedestrians. The issue has become so concerning that my daughter refuses to drive the vehicle because she no longer feels confident that it will stop properly when she applies the brakes. A driver should never have to question whether a vehicle will respond correctly during normal braking. After researching the problem, I discovered that Toyota has already acknowledged this exact condition by issuing Technical Service Bulletin (TSB) TSB-0059-23. The symptoms described in the TSB closely match the behavior my vehicle is experiencing. I therefore requested that the dealership inspect the vehicle and perform the repair outlined in the bulletin. Instead of addressing what appears to be a known braking-related issue, the dealership informed me that I must first pay a $190 diagnostic fee before they would even determine whether the TSB applies. I believe it is unreasonable to require customers to pay to confirm a condition that Toyota has already documented, particularly when it involves the vehicle's braking system and potential safety risks. I am concerned that other owners experiencing the same braking behavior may delay seeking repairs because of the required diagnostic charge, leaving potentially unsafe vehicles on the road.I respectfully request that the federal safety agency review this issue.

I pushed the brake and swerved and the car kept going and a greater speed and surged into a house.

My 2020 Toyota Highlander hybrid sometimes has a brake slipping or surging sensation when I apply my brakes while stopping. It happens periodically and not every time. I have not taken it to a Toyota service station for this specific reason but I mentioned it while in for a recent oil change. They checked for a recall but didn't find any. I have somewhat gotten accustomed to the issue and have been able to adjust. As I have stated, it doesn't happen every time I apply my brakes. My concern is if I allow someone else to borrow my car or even sell to a new owner. I believe I am the second owner.

The Pre-Collision System with Pedestrian Detection is a good thing, but there's a problem. It stops the car too abruptly on the highway, leading to rear-end collisions. When you release the brake pedal, the car remains stationary. To get it moving, you need to press the accelerator pedal. There have been four instances of the Pre-Collision System with Pedestrian Detection being activated in the last 12 months. Two of them ended in rear-end collisions. In the other two cases, there were no cars behind.
