Went to someone's house today. Parked in their driveway. The driveway slopes down forwards pretty good. My guess is around 6-8 degrees. Put car in Park. Car held in place. All good.

Then, came back and started the car as I normally would. Put the car in reverse, and the car started rolling FORWARD!

Quickly hit the brake, didn't switch gears, and went from brake to gas pedal, and the car started rolling FORWARD again. So I gave it a little gas, gently, and the car was still rolling forward.

I went back to the brake pedal, and started giving the gas pedal some go at the same time, as if you'd be launching forward (not floored of course, but kind of that concept), except in reverse lol, and the car moved backwards.

It was a really weird experience. Haven't had this happen in my BMW's on the same driveway, and this wasn't a thing in my L494.

Anyone else had a similar experience?

Ermmm... only since the advent of torque-converter automatic transmissions, in general? '41 Oldmobile, Dad's case.

If/as/when the torque converter is below design stall point, power is near-as-dammit 'de-coupled'.

Above stall, it still has to be pushed up into the range where it transfers enough torque to match, then overcome, the load imposed by.. in this case.. ignorant gravity pushing-back.

Compromises.....

There's only but so much complexity, 'intelligence' and ....guesswork ...one DARES design into a motor-vehicle before possible 'wrong guess' by the machine becomes more dangerous than potential wrong choice by human operator.

This vehicle is different from the others you parked, same place.

Just Deal With That.

Was brake hold on and it was still rolling forward? Also was Hill Start Assist turned on?

 

No, neither of these were enabled

 

Welllll.. then you are down to brake/accelerator physical coordination to adjust relative forces 'yourself'.

Same as any other motor vehicle built since "big bang"? Only mules, horses, Jinriksha runners had their own 'independent' and autonomous sense of balance & such...

Pretty much "accidental" that some OTHER motorcar had a different behaviour - same driveway. Rovers are usually heavier than average for their size.

Be happy your weren't dealing with a twin-screw Peterbilt and 80,000 pounds of steel.

 

I've noticed the throttle response in reverse is calibrated different from the forward gears (and to that of other cars). I find I have to apply more pressure to the accelerator pedal to get the same motion as when in "D". I can see the scenario of it rolling forward as you'd really have to get on the gas to get it to respond in "R".

 

THIS! Exactly this!!

 

So i didn't have the exact issue - but I did have an issue of the car accelerating on its own.

Driving forward down a straight avenue - no incline of any kind - I put my foot on the gas ever so slightly - and the car correctly moved forward, I took my foot OFF the gas completely - the car continued to move forward - and as I assume it would slow down as momentum reduced, it did not. It actually began to accelerate AS IF my foot was on the gas!

It was an awkward drive. It has not happened since.

 

Interesting. Definitely some quirks sometimes

 

I’ve had this happen both on an upward incline in D and on a downward incline in R. In both instances the car rolled the opposite way of the gear it was in. From time to time, I’ve had issues with it going into the gear I select especially from R to D. I have to select the gear multiple times always ensuring the brake is fully pressed. It’s glitchy and doesn’t happen all the time. I too have never experienced this in my BMW. In R on a downward incline, I can take my foot off the brake and the car remains in R and doesn’t move. The same applies to hills in D…. Foot off the brake and the car remains stationary. IDK… definitely different experience.

 

Exactly. Something handles just a bit oddly in this gen rover in these use cases. It doesn’t happen in other brands and this also didn’t happen in my prior gen rovers

 

Auto hold is supposed to prevent this situation.

 

So here’s my issue with this. Yes. Auto hold will hold the car in place when you brake. And it would fix the issue I’m sharing. But, it’s annoying because in stop and go traffic, it’s nice to be able to easy your foot off the brake and just roll a little.

What I’m looking for is more of a “hill assist” which the old Rovers seemed to have and the bmw’s have, which basically holds the brake for a few seconds when you let go of the brake and move to the gas and when you’re on an incline.

 

I have experienced the same thing when I reverse my loaded trailer up my driveway which has a slight incline. I simply add a little left foot brake as I push off in reverse and problem solved.

Without a little left foot brake, you'll really spin up the clutch - and likely cause some unnecessary wear to the trans.

My Pdk trans 991.2 GT3 RS needs this gentle assist as well as it has no interlocking capability at all and will slip back without some assist.

I kind of like having to finesse the old Range Rover up the hill - reminds me that it basically weighs 3 tons - and I can feel every bit of it when I do have to assist it up a hill.

It's always good to see GT3RS on slicks 👍

 

Yeah.. this whole thing.. obviously is what it is, but it could be implemented much better. These cars are so electronic these days, having a software enforced few second brake hold when an incline or decline is detected as part of a hill assist feature would be so easy to implement.

One other thing I’m wondering, the bmw only works with the hill assist feature up to a certain incline. I’m wondering if the rover might have a similar feature but I’d this gradient was more than what the feature supports.

The Range Rover definitely has Hill Start Assist.

 

So, this is getting worse. Even a slight forward decline, say in a parking garage, the car is rolling forward when you put it in reverse. This is NOT how the car used to be. Something is definitely wrong in my opinion. Car is going back tot eh shop next week.. in addition to the other set of issues it's going back in for..
