Sudden acceleration when applying the brakes. This has happened several times

- Louisville , CO, USA

We have noticed that when we brake the vehicle, it intermittently LURCHES FORWARD very fast while you are breaking and trying to stop! This is extremely unsafe! We need to stop and brake and not go forward. It does this unexpectedly with no notice and does not always do it consistently but we have noticed it is getting worse and worse and we are worried we will hit another car in front or even a person because the car will not stop on time. When I looked online, this is a well known issue on Toyota Highlanders, especially hybrids like ours and Toyota has done nothing to fix this dangerous problem. They have even told car owners to drive slower but I can tell you it doesn-??t seem to matter if I-??m going 25 mph or faster or slower- the car gives no notice and goes FASTER while you are trying to stop!!!!! Please help us Toyota Highlander owners!!!! This car gives us no warning whatsoever. It is not consistent. But when it does this it is VERY scary!

When braking the brakes will occasionally -??quit-??, causing unexpected acceleration. They kick back on if I stomp hard on the brake, causing the occupants to jolt forward. It could easily cause a collision if an unexpected vehicle or pedestrian were in the way, and could cause a rear end collision were I to have someone following close behind and hard brake unexpectedly. This has been reported to the dealership but they have been unable to replicate it. It happens intermittently, primarily when braking on a slight downhill slope. The issue has been since the vehicle was new. No warning lights or alerts activate inside.

Degenerative breaking. When breaking sometimes it jolts- seems to lose braking power. This is a safety hazard. It could cause a crash.

- Oakland, TN, USA

Loss of brake sensation when slowing down through 20-25mph. Brake pedal takes a sudden plunge and car surges forward, forcing the driver to suddenly have to push hard on the brakes in order to stop. Usually happens under moderate braking, especially when there is a slight downhill grade. Toyota dealer confirms that it happens but says there are no codes and there is nothing they can do. Toyota dealer service advisor has had it happen to him while driving. This happens regularly, as often as 2-3 times per week, and can be reproduced.

When I brake, the SUV feels like it accelerates/surges forward rather than slowing down. I need to apply the brakes hard to then stop the vehicle. I never know when it will happen but it happens very often.

- Wendell, NC, USA

when I slow down to make a right or left turn I apply pressure to the brake pedal and my vehicle brakes feel like they are "gulping: or not holding, causing my vehicle to lurch forward slightly. This has been happening since I purchsed in July 2022. I replaced my tires last month thinking it was the tires, but the vehicle still lurches forward when braking in a turn. I will put the last time this occurred in your details below

On March 16, 2024 this vehicle experienced a complete brake system failure. This is a very serious braking issue and the vehicle has had several braking incidents leading up to the complete failure. Toyota Motor Corp has dismissed the issue each time as there have been no codes or warning lights prior to this incident. We filed a complaint concerning this braking issue on June 12, 2023, Ref#11526496 Since that first report there have been several other incidents where the brake pedal went soft and depressed to the floor as the vehicle accelerated forward. Since the complete system failure occurred on a Saturday, as of this writing, it has not yet been reported to the service department. We filed a complaint with Toyota Motor Corp stating that this is a very serious safety concern that could lead to injury or death and they dismissed it.

Brakes vibrate at highway speeds above 60 mph. Car does stop but steering wheel and seat noticeably shake. Car only 1 year old and started during winter. Seems to be related to TSB-0072-18 but does not cover my vehicle year.

Occasionally when slowing to a stop, the brakes feel like they slip and i begin to speed up suddenly. Pressing hard on the brakes stops the car again. This is a safety issue if for example you were braking for someone in a crosswalk or a car in front of you. The dealer was unable to reproduce the issue. It happens maybe once a week, for the last several months. They examined the brakes and said they are fine. No warning lights.

Unexpected brake failure; While driving at a slow 20 to 30 mph speed lightly braking anticipating a stop at a stop sign my car will unexpectedly surge and jolt the car forward while I'm applying maximum brake force to the peddle. I took it to the local Toyota dealer they checked it out and couldn't find or replicate the problem. I was told that possibly my driving habits or I may have my foot on the brake while still on the accelerator?? When this happens there are NO warning indicators or audible sounds either lit on the instrument panel prior to or after the event. This event on this day propelled my car approximately 6 ft past the crosswalk into the intersection of a four way stop.

A few months after the winter of 2022/2023 the car started making noise and shaking while breaking, the car was taken for regular maintenance at the dealer and I was told everything was fine on April/2023, it just got worse over time and the breaks are now failing and not stopping properly due to huge clusters of rust in the rotors. Car was taken again to the Toyota dealership and they said the warranty does not cover the rotors as they are considered wear and tear parts, rotor isn't worn but has increased in thickness in the areas were the clusters of rust are. After speaking to another mechanic I was told it happened because of the low quality steel of the rotors used by Toyota, which do not perform well in a climate where salt and other chemicals are used to treat the roads. The breaking quality has reduced so much the vehicle is taking twice as long to stop putting myself and others at risk.

The brake system on the 2022 Toyota Highlander Hybrid malfunctioned momentarily this weekend (7/8/23 was date of incident) in North Kington, RI. While coming to a gradual stop at a stop light, the brakes momentarily stopped working and felt like the car lunged forward before the auto braking system activated since there was a stopped vehicle in front of us. My foot was on the brake pedal but the brakes just stopped working for a moment. I've read in other toyota forums that this has happened to others with 2022 hybrid highlander models. The same issue happens when applying the brakes going down hill and going over a bump. I'm bringing the vehicle to the toyota dealer this week. No warning lights ahead of the problem.

While driving on the highway at an average speed of 40-60 mph and applying the brakes, I experience a noticeable shaking in the whole car and can also feel the tires shaking. I took my car to the Toyota dealer, and they confirmed that the rotors and brake pads are in good condition. However, I still do not feel safe driving my car at this point.

On June 26 2023 the vehicle didn't stop automatically when another car was in view in the intersection, the automatic breaking system didn't work and the air bags didn't deploy,

When I am slowing down to a stop usually when im going down hill the brakes will fail and the car lunges forward. It will fell like I am stepping on air. I have taken ot to the dealership but they have been unable to duplicate the issue so I dont know what else to do. At the begining it was pretty rare but now it is happening more often

While driving in town and coming to a stop sign at a four way intersection I applied the brakes at under 15 to 20mph to stop and my vehicle lurched forward and my brakes were unresponsive. The brake peddle got very spongy for a split second and immediately returned to normal. When I finally stopped my Highlander was half way out into the intersection. This is about the third time it has happened since I got the car in April 14, 2022. Each time it has happened I remember the roadway surface being very rough and full of small potholes or a uneven braking surface.

On multiple occasions the breaks appear to momentarily slip, resulting in the car lunging forward. This tends to happen when slowly decelerating, especially when going down hill. It happens at random, regardless of weather or road conditions. I reported the issue to Toyota two services ago and they stated they were unable to replicate the issue despite driving my car 20 miles. Their best guess was that the ABS system is engaging briefly (Ok. That's an issue. They say there's nothing they can do). Both my husband and I have experienced this issue. It's incredibly unnerving and I'm worried it has potential to cause an accident. I have noticed an increase in occurrence over the past few months. I try to document the date and time of each incident. Additionally, the few times I've needed to brake suddenly (rare because I stay pretty far behind the car in front of me at all times, especially given my concerns) the breaks take a moment to register. When you need to break immediately and press on the breaks firmly to do so, they should respond instantly. That does not happen here. There's a few moments of no response before they finally engage. All in all, the breaks/breaking system on this car really worry me.
