Roll backwards in drive

Good morning boys and girls.

Sometimes, in the time it takes me to go from the brake to the gas - say at a light - I roll backwards ever so slightly. This morning, it was more than ever so slightly. So much so, my nephew looked at me like I lost my mind and said what the hell was that. I wasn't even on an incline. Me no like. Am I going to have to start driving with two feet? If someone was up my butt, I would have rolled into them.

Anyone else?

Thanks!

Shouldn’t be happening. I would take it to the dealer and have them sort it out. In the meantime use the auto H feature so you dont rear end anybody

That's the way the new transmission works. I push the auto-hold button now as a matter of habit, which resolves the issue and makes it work more like a traditional automatic.

There should be a couple seconds before rolling backwards... Not immediately from brake to gas pedal...

I concur, they new transmission treats it more like a manual vs an automatic, just be careful and don't forget to put your foot on the brake or engage auto-h when you are at a stop.. especially on a slope.

Yeah, exactly. The good thing is that you can see it light up on the display when auto-hold is actually engaged and working.

Thanks all. I read on another forum that there is a 3 second delay. It sure felt faster than that, I'm quick from brake to gas when the light changes. The bizarre part is that I wasn't on an incline. I guess I'll be using the auto hold.

When I read the manual the explanation was somewhat confusing as far as activating and deactivating. It said to apply brake to deactivate, but then it said when activated it will engage after you come to a full stop. I used it last night. You just press it and forget it. Is that correct?

Yep. The only thing that sucks is you have to press it every time you start the car.

The rolling-back is definitely normal behavior for the car. I kind of like it because it gives this big sport 'ute a manual transmission feel.

You gotta just apply the brake or use the Auto-H function behind the parking brake.

Thanks Phantom, I had to learn the hard way. I never had a need to use the Auto H before. It is now an automatic thing, instead of taking off the parking brake, I just put on the auto hold.

I have however, rolled both backwards and forwards when Auto H is activated. It's a bit unnerving. Not sure why this happens. It has happened to me when shifting from drive to reverse, and reverse to drive.

All M transmissions behave like that. It behaves like a clutchless manual.
