When I driving slow and begin to brake the car does not slow down or stop. It feels like I'm hydroplaning.

The brakes on the hybrid system release during braking. Which send the van lurching forward, this typically happens a lower speeds, under 20mph. Which makes it unsafe as you do not stop when you are expecting.

while braking and coming to a stop the van surges forward (while brakes are being applied). This has nearly caused accidents on 2 occasions, and has happened 2 other times in the past few months

When braking, there is a sudden jerk and surge in power at low speeds. It feels like you are losing control of the car. It feels unsafe to drive the car.

2023 Toyota Sienna occasionally, without warning, "lurches" forward at low speeds when braking. While putting steady pressure on the brake when coming to a stop at a stop sign or traffic light etc. it feels as if the brakes stop applying pressure and if we wouldn't have quick reflexes to brake harder, we would roll out into the road or into the car in front of us. I believe it is something to do with the transition between regenerative braking (vehicle is a hybrid) and the hydraulic braking. I have spoken to Toyota, and they don't have any recall. People posting on online forums seem to believe there is a software update (T-SB-0047-24) that helps address the concern. Toyota charges to diagnose and apply software updates as the vehicle is out of warranty. I believe this to be a safety issue and something Toyota should cover. Based on my online search, there seems to be a lot of people with the same issue. This has been an ongoing issue the last couple of years and I'm thinking it should be reported. I have not brought this to a dealer to have diagnosed. These are largely family vehicles and my wife, and I don't feel very comfortable every time it happens.

Front brakes make a clicking noise that happens when accelerating and breaking, the brake pads may have some play or even the calipers may be malfunctioning. Vehicle is still under warranty and Toyota service center refuses to address the issue. They want me to spend $160+ to have them grease the brake pads, but they don't guarantee that this will fix the problem. On a fairly new hybrid van that has almost no wear on the brakes, this shouldn't happen, and when it does, Toyota should acknowledge and address the issue.

Brakes will intermittently lurch when coming to a stop with normal braking pressure. The lurch feels like the brakes have stopped working and the driver has to press harder on the brake to avoid rear ending the vehicle in front. Brake pedal feels normal the entire time. Dealership is unable to duplicate on a test drive since the issue is intermittent.

When I go to brake the brakes seem to malfunction and skip engagement. I’ve had acceleration happen in the vehicle when I brake. At one time this caused my speed to jump while braking, I went from 5 to 10 MPH. This now happens several times a week.
