I think that there could be an issue when turning the car off. If you stop on an incline and have your foot on the brake pedal and then power the car down with the “Blue power button” with the selector in “Park” the servo seems to leak pressure and the car will start to roll. OK this is arrested to a certain extent when the bolt engages in the gearbox. This however may not happen if the incline is steep. I feel that on powering down the car the electric parking brake should be automatically applied to ensure that the above cannot happen. After all the car take the brake off when you want to start why can’t it put it on when it knows you want to stop. A safety issue here I think, and it is not good to put that kind of pressure on the gearbox mechanisms.

Are you talking about just locking the transmission (Park selector) or using the (P) Handbrake also? the transmission will have more play in it than the proper parking brake, but on a hill the suspension will roll as weight shifts from the front to the rear brake.

I agree there is no reason (that I can think of) not to automatically apply the Electric handbrake on power down.

IIRC (If I remember correctly) the Leaf automatically puts on the electric park brake when you shutdown if you haven't done it already. I can think of no reason why the Ampera shouldn't do the same.

Don't forget peeps... we should not be leaving our car without the park brake applied - even on flat ground. It is a requirement of us to secure the car and we should not be relying on the transmission (either manual or auto) to do that for us. I know that it is common practice for some drivers of auto cars not to use the park brake and just to put the selector into P but that is not sufficient as it then relies on the various parts of the engine or transmission to stop the car moving and that is not as reliable as applying the park brake. ;)
