Van has just over 5k miles. Multiple warnings occurred while at speed on a highway. Primary warning was 'Low Brake Power' and braking became extremely touchy as it seemed to utilize the emergency brake as a backup. This extreme braking is hazardous and could result in an accident caused by braking too quickly - with a possible rear-end collision by traffic to the rear. Additional warnings/malfunctions were listed as well, due to the low brake power: LTA Malfunction (Lane keep assist), Automatic Emergency Brake Malfunction, Parking Brake Malfunc…

Owner report 11426402 · 2021-07-26 (July 26, 2021)
We were driving down the freeway when we got rear ended hard by a large pickup. Then we lost electrical and engine power. The brakes stopped working. The hazard lights stopped working. Luckily we were able to coast to a complete stop as there was no way to stop the car. The police came and took a report. Then the car was towed to a body shop. We're awaiting the insurance company adjuster for inspection.

After the vehicle has been parked for a while (>1 hour in my experience), upon startup, when reversing down a hill, the brakes give the following intermittent (maybe one out of four start ups) problematic behavior. When releasing the brake pressure gradually, the car will not move, until suddenly it lurches and rolls backwards significantly, the pressure on the break feels like it is reducing and the brake stroke length releasing. To stop the car rolling backwards you need to push down several extra inches on the brake to get it to stop. I have…

Braking is slow or non-existent on random occurrences. Although the car is automatic, it feels like you are pushing in the clutch when brakes are needed. At times when braking too, it feels as if the car lunges. On two occasions, I narrowly missed hitting an object. Its as if the braking hesitates. The dealer said that this is the design based on the vehicles software. They asked us to call Toyota’s customer service to complain.
