2023 Toyota Highlander Brakes Problems

Your brakes aren't responding normally when driving downhill—instead of stopping smoothly, you experience a sudden surge and the car takes a few extra seconds to brake. This happens frequently, forcing you to maintain extra distance from other vehicles to avoid a collision. The Toyota dealership has been unable to identify or fix the problem, and no warning lights appear on your dashboard.

Randomly when braking the vehicle will "lurch" forward causing you to immediately reapply the brakes hard to stop. The dealer claims they have no knowledge of this but when you Google "Toyota Highlander hybrid brake issues" there are numerous reports of the same occurrences. This creates a serious collision potential issue with a vehicle stopped in front of the car.

Your brakes failed completely while slowing down at 8 mph, even with your foot pressed all the way down on the pedal. Your forward collision warning system also did not activate, and your airbags did not deploy despite the crash. You believe this may be related to how your hybrid vehicle switches between electric and gas braking systems, especially since Toyota has recalled earlier model year hybrids for similar brake failures. A technician should inspect your brake system, hybrid braking components, and collision avoidance system to determine what prevented them from functioning.

When you brake, your car sometimes surges forward as if the brakes briefly release in the middle of stopping. This happened while braking and nearly caused you to hit the car ahead of you. The issue appears to be a momentary loss of braking pressure rather than consistent brake failure. This will likely require a brake system diagnostic and may involve servicing or replacing brake components.

Your brakes are losing pressure without warning, causing your vehicle to suddenly surge forward. This happens in various situations—going downhill, turning, or parking—and is becoming more frequent (now daily instead of once or twice monthly). Toyota acknowledges this as a known issue called "loss of braking sensation" with a technical service bulletin for older model years, but no fix is available for your 2023 hybrid model. Resolving this will likely require Toyota to develop and release an official software update or hardware modification for your vehicle.

Your brake pedal occasionally stops responding and requires you to lift it up and press hard to regain braking function. This issue created a dangerous situation where you nearly had an accident. The problem appears to be a known issue that Toyota should address.

Your Highlander Hybrid's brakes may suddenly feel different and lose pressure when slowing down to a stop, especially on hills or in heavy traffic, causing the vehicle to lunge forward and requiring you to press the brake pedal very hard to stop. This problem occurs during the transition between regenerative and hydraulic braking at low speeds. The repair may involve a software update or recalibration of the hybrid braking system to smooth the transition between the two braking types.

When you brake, especially going downhill, your Highlander sometimes lurches forward before the brakes engage and stop the vehicle, which feels jarring and unsafe. Toyota mechanics have told you this is normal for hybrid vehicles, but you've found many online reports from other Toyota hybrid owners experiencing the same issue. The brake system may need inspection or adjustment to improve the braking response.

Your 2023 Highlander Hybrid may have a braking issue where the car doesn't brake smoothly when switching from regenerative braking (which captures energy when slowing down) to regular friction braking. You might notice you have to push the brake pedal harder than expected during this transition to get the car to slow down properly. The fix would involve a software or hydraulic system update to ensure smooth braking transitions.

Your 2023 Highlander has two issues: (1) At only 25,000 miles, your brake rotors warped and caused severe vibration during downhill braking. Toyota resurfaced them under warranty inspection, but you're concerned they'll fail again since less metal remains on the rotors. (2) After installing a third-party receiver hitch and bike rack, your backup warning sensors and kick sensor malfunctioned—the sensors detect the bike rack and apply the brakes, preventing you from backing up unless you disable the safety features entirely. Toyota confirmed there's no fix, yet they sell hitch and bike rack options for this vehicle. Resolving these issues would likely require brake rotor replacement and Toyota reprogramming the backup sensor software to ignore the bike rack.

Your 2023 Highlander vibrates in the steering wheel, brake pedal, and body when braking at 25 mph or higher, especially on highways. The vibration continues even though you've had the brakes inspected multiple times, purchased new tires, and had them aligned and balanced, and Toyota Service confirmed the brakes are in good condition. The underlying cause hasn't been identified despite regular maintenance checks. A technician will need to diagnose the source of the vibration, which could involve inspecting brake components, suspension, or wheel balance more thoroughly.

There is a wobbling sensation on my Highlander during braking at highway speeds. There is no such feeling while driving around city. It appeared after my trip on highway in heavy rain.
