No haven't had this on mine, if the clutch is at biting point then there will be no roll back, the steeper the hill the more gas you need for the EPB to release. Land Rovers GRC (gradient release control) only assists with hill starts, makes them smoother but won't prevent rollback. With the auto, the car will stay put until your foot is on the gas.

Gradient release control only works when HDC (hill descent control) is activated. Nothing in the manual about hill start assist in the manual. 21MY Defender 90 S 3.0 D200 |

There is a video on you tube demonstrating HSA in the Evoque, 2 seconds is all the time you have to move your foot from brake to accelerator.

I look forward to enlightenment as I didn't think the FL2 MY13 had 'Hillstart Assist' as in normal road use, it has the usual stuff with GRC linked into HDC and auto handbrake release but 'H/A' doesn't even show up in the spec on their site but does on the Evoque. |

I don't think it has either all I can find is GRC which is only active with HDC. 21MY Defender 90 S 3.0 D200 |

Just had this explained and demonstrated to me on a LRE in an auto, don't know how a manual is supposed to behave.

Was that bit onroad or offroad, terrain response on or off and was HDC on What I believe is HillStart Assist is not a part of a FL2 for road use but would love to be proven otherwise, GRC will hold the brake in off road or extreme conditions on a steep incline as you describe as long as HDC is on and the EPB will auto release after accelerator is applied on road, or off road come to that.

Offroad with TR and HDC on, however from the way it was explained I had understood it to be a universal feature and it had been described as a hill start assist, but I couldn't say for sure whether it was unique to one mode. HDC was on to demonstrate the sense of having it enabled even when hill climbing in case of emergency, or some immediate need to descend. On or off road I still don't see why the 3 second limit is imposed. |

I don't know why the 3 second limit is there either, the electronic throttle and adequate torque could trigger the brake release.

Mines got hill assist, comes on with a gradient, nose up or down on normal everyday driving conditions with normal terrain mode and no HDC switched on.

Hill Start Assist(HSA) and Gradient Release Control (GRC) are different systems although they do much the same job.
