The vehicle started experiencing the vaccum leak in the master brake cylinder/actuator/booster where the booster pump would run continually every 15 seconds causing the danger to brake failure. Dealer was contacted but refused to help. Eventhough toyota prius hybrids and newer and some other toyota that share the same design brake booster and master cylinder has been recalled previously. It is common failing component but dealer does not provide any assistance leaving vehicle owners pay thousands to replace abs brake components and bleed the system. Need your help!

I attempted emergency braking on elevated highway during snowy conditions. Speed was approximately 40-45 mph. Pressed firmly on brake pedal and nothing. Nothing. Began pumping on brakes and still nothing. Steered car away from braking vehicles in front of me and veered car into median wall to avoid rear end collision.. severe damage to car, but no air bag deployment and avoided hitting any other cars. I've had ABS on multiple Toyota and Lexus vehicles in the past, I have never experienced anything like this. There was no braking. I have pictures of the car, but the damage was due to hitting the interior highway wall. This is a certified Lexus vehicle that I purchased just over one year ago (12/31/19). I just had my second six month check up covered by Lexus under warranty. Mileage is approximately 36K miles.

A delay/slippage is occurring not from brakes but within the pedal inside the car when apply hard stop., changed brakes and rotors but noise still occurring I believe its from the brake booster or the electronic brake pump. No recalls found for 2016 but same issue and recall found in 2019 Es300H. I've been experiencing this since I bought the car but didn't think much of it until my certified master tech looked at it. And the look on his face was scary.

April 26, 2019 was driving with family our 2016 Lexus Es300H on I-44 West, heading into joplin, mo. The radar cruise control was set to 75 mph, and I was driving in leftmost passing lane behind a car going about 65 mph, which kept my speed also at 65 mph. The car directly in front of me moved to an open lane to the right, with clear path in front of my vehicle to allow acceleration up to 75 mph. Note: It was a clear day, slightly cloudy, road was flat, no curves. Instead of accelerating my vehicle suddenly instead applied the brakes, the accelerator pedal not responsive to anything I did to increase or maintain speed, with vehicle quickly coming to a stop as I moved into the grass median area separating the freeway before car died in the passing lane. Collisions was barely avoided as pickup truck behind me slammed on their brakes and veered into median grass to avoid hitting me or getting rear ended themselves from behind. My car came to a complete stop even though entire time I had accelerator depressed. Once stopped I exited the car, talked to the other driver, who informed me my brake lights were on during the entire incident. I went back to the car which was still running, car once again responded to accelerator being depressed, and we continued our journey. It appears the pre collision system which this car had turned on at the time improperly engaged, even though nothing was in front to have caused proper activation. We were lucky, we could have easily been rear ended by a semi-truck as they heavily travel this freeway, or possibly been in a location where there was not a good shoulder to allow the quick stop with minimal impact to traffic going at high speed.
