I guess hill hold brakes came along since 6.1. I have MS Classic (Sept.14) with no auto-pilot gear. I have it turned on. And I've witnessed it working, so I've seen it do its job. Yet, in similar stopped situations, I've also witnessed no holding after taking my foot off the brake. The car will roll forward or reverse as soon as brake pedal lifted. It's been like this ever since I've had the car... and same through every software release since. Not sure if this is by design or something else? Are there a specific set of criteria under certain conditions that must be met for a hill hold happen? I've tried experimentation looking for a repeatable and predictable case: Degree of slope. How hard I press on the pedal at the stop sign, before release. When I apply brake (late or early) in the slope of regen doing most of the work. How hard or fast I initiate braking after getting off the accel pedal. Putting the brakes on only after regen has practically stopped the car. Repeated application of brakes at the stop sign. The amount of time at rest with pedal pressed. blah blah blah Can't find a pattern. Are there situations where we can expect hill hold not to happen (by design), even when switched ON? Not that this matters hugely... it's just nice to know if we have a "sometimes" feature, when turned on. I'd expect an ON feature to always be the same and react the same... right now it seems the car is just moody. FYI, I have Creep OFF, always keep it off.
