NHTSA complaint: 2021 TOYOTA redundant SIENNA — UNKNOWN OR OTHER
When breaking, mostly during downhill, the brakes feel like they simply âlet goâ 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.
