Consumer Description

When breaking, mostly during downhill, the brakes feel like they simply “let go” for an instant. Most times this is very short and It feels like a typical downshift during breaking in an ICE car. However, last time it really gave me a lurch and I almost ended up falling off a cliff face. Many reports all over the internet but nothing from Toyota.
