2021 Toyota Rav4 Brakes Problems

Your brake pedal may suddenly lose all stopping power and go to the floor without warning, even though brakes were working fine moments before. Your forward collision warning system and automatic emergency braking may also fail at the same time. The brakes may mysteriously start working again after the incident, making diagnosis difficult, but this is a serious safety issue that requires professional inspection of the brake system's hydraulic lines, master cylinder, and electronic control modules.

Brakes lights comes on while driving n the two wheel front makes a grinding sound while still driving… a friend of mine had the same problem took her rav4 2021 to windward toyota Kaneohe hawaii several times n finally on the 5th service was told that it’s her secondary brake system and in my Toyota the LTA DISPLAY WAS ON MY DASHBOARD DISPLAY

Critical safety concern regarding the braking system in my Toyota Rav4, 2021 which I believe may warrant further investigation for a potential recall as there are none at this time. The issue pertains to the breaking system, which locks up unexpectadly during use, casuing sudden and severe break locking without warning (unable to break). I suspect as many others online who have mentioned this issue on Toyota Forums is that it is the prime breaking software. I have had my breaks inspected multiple times as I was in a car accident where the breaks did not work and I rolled into the car in front of me when we were starting to proceed through a green light at 5MPH. When pushing on the brakes nothing happened and I rolled into a mother and children. Luckily I did not cause significant damage however I explained to her my breaks would not work. This accident then caused me to be dropped from my insurance (policy termination by Geico) since I had switched providers and happened during my 30 day grace period. This malfunction created a significant safety hazard for myself and others on the road as well as fear that it will happen again and should be investigated as I have have this happen multiple times since the accident. Geico claim number: 8817814110000001

I was on highway 41 going around 40mph when my car out of nowhere slammed on the breaks ( the pre collision censor ) I believe is what caused it. About 10 mins prior to the incident when I was backing out of the gas station it braked (abruptly with noise) even though nothing was in the way or approaching my vehicle. I would say that I was stuck in the car for about 5 mins before I could get it to start driving again. The electrical flashed and shut off right when the car braked. I did have my two dogs in the backseat and thankfully no one was harmed.

While traveling on highway with adaptive cruise control engaged and maximum following distance selected, adaptive cruise control applies excessive braking force than necessary when vehicle in front exits highway. Safety concern because following vehicles must abruptly apply brakes. Internet search reveals numerous, similar complaints. We were almost rear-ended on the highway. This feature is great, but needs attention for safety reasons.

2021 Toyota Rav4 Hybrid XLE Premium. Purchased new from the dealer. It currently has 75,000 miles (predominantly highway). Condition: The Braking mechanisms behind the firewall intermittently make a noise when the brake pedal is pressed fast (emergency) and/or released. It sounds like a seal barking when the pedal is moving either up or down. These are not your typical noises from a pad or rotor wear. Cause: At approximately 28,000 miles, the seal barking sound was there but very faint. As I added miles the sound became more frequent and louder. I did take it to the dealer who was not able to help. Environment: This seal barking sound can happen at any time and any condition, but is almost always going to happen when I want to avoid hitting an object that suddenly appears in my lane of travel and must brake quickly. Research: I’ve researched several Toyota and Lexus owner forums and found that other owners have the same issue. They described the sound as “seal barking” or “farting” (sorry for the wording, but that is what was used in the forums). Other forum members stated that it could possibly be tied to the master cylinder, brake actuator pump or ABS Brake Pump Booster (or all of them). Conclusion: I’m very concerned because this noise happens when brake components are activated and then may lead to failure. Please let me know if you need more information or an audio recording of the condition.

As I was on my driveway I pressed down on my brakes to stop the car but it didn't stop. I immediately pressed on the brakes all the way down to the floor of the car and the car still didn't stop. The assisted brake system stopped my car as I tapped my garage door with the car's bumper.

Driving about 35 mph, I pressed break pedal approximately 50% in order to stop at the light ahead. When the car reached somewhere around 10-20 mph, the degree of deceleration sudden decreased (the car was still slowing, but the rate of slowing suddenly decreased) without any change in a degree of depression of the break pedal. The road had a couple of bumps on it, and I have noticed that this seems only reproducible when the car is going over bumps during the deceleration. I was able to find a forum that describes similar behavior related to other Toyota Hybrid vehicles https://forums.edmunds.com/discussion/5357/toyota/highlander-hybrid/highlander-hybrid-brake-problems

During inclement weather (snow) this morning, I went to brake and it felt like my car sped up instead of slowing down. I tried pressing my brakes again and it did the same thing again.
