PSA: Careful Parking on ANY Incline...

[Dark-Fx]

We got that same shit weather overnight last night. There's no way I would have parked anywhere on an incline this morning that was covered in this stuff. Granted, if you had snow tires it might have still held the vehicle in place.

I don't totally understand the mechanics here but if the Rivian parking brake is just telling the motors to lock in the rear, could an OTA update make the parking brake to tell the front tires to also lock? Seems like that could help (but not totally prevent) this issue by spreading the job across all four tires instead of two.

There's an electromechanical device for the parking brake, it's not just using the normal braking system.

I remember Munro appreciating Tesla for not building a parking brake pawl as it was unnecessary cost. I guess Rivian followed Tesla here, as they did with AA/CP and PAAK.

Munro mentioned that some traditional makes build parking pawl into motors unnecessarily ?.

This is probably not worse than RWD ICE vehicles and Tesla. FWD/FWD based AWD, certain full time mechanical 4X4 vehicles will lock all 4 wheels when parking brake and transmission park are engaged.

If it's not a locking differential, it won't make much of a difference. Once a tire slips you'll get the higher traction tire rolling and the slipping tire will spin opposite. It's why you're supposed to turn towards the curb on steep hills, it forces the vehicle to have to drive up something, which it won't do without momentum.

Fortunately, it only broke the charger handle. Metal pins are now exposed as the plastic surround was shattered. I still need to get time to test the charging port on the truck, but it doesn't look visually disturbed at all.

This is a perfect argument supporting a “quick disconnect” feature added to these charger cables; similar to what they have on the pumps at the gas station for safety in case someone drives off and forgets to take the pump out of the car.

Not like I’ve ever done that…or anyone has ever said to me “happens all the time”.

Interesting that nobody has mentioned these (although someone mentioned using firewood or something like that).

It's a requirement for the vehicle to be disabled if it's plugged in.

Most definitely. But if it slides like in the video and as seemingly reported by others, the quick disconnect should minimize damage to the vehicle’s charging port and the charging cable.
Just an idea.

Maybe it should be standard procedure to tie a vehicle down after parking.

Different incident? Reported by autoweek 2/17/2023

“An owner in Seattle told NHTSA that the R1T, in the “park” position, started moving backwards down a moderate slope. “I was able to reproduce this effect multiple times on similar slopes that day,” the owner said.”

Easy to find hundreds of videos like this, none of which involve a Rivian:

Any car can slide, but it would be nice if a car billed as an off-road adventure vehicle could use all four tires for traction when parked instead of only two, which is in line with other FWD and AWD cars. Case in point, it was extremely difficult to change a rear Rivian tire in snow on an inclined icy mountain pass by the side of the road, because the grip of only _one tire_ was keeping the entire car from sliding downhill. And Rivian doesn’t sell winter tires, and nobody else makes them for 21”. Pretty dangerous. I speak from experience. On a gas car, you’d at least have the transmission locked on the front wheels.

At some point weight and slope will overcome tire grip. Car will slide. Heavier car = easier to slide. Snow tires will help, but again, given time, melting (think ice skates: thin film of lubricating water) the vehicle will slip. Wheel chocks-- just another object to get pushed down the hill--given enough weight of vehicle and angle of slope.

Park in the garage!!!

I'm not the OP, but I will definitely try to catch the next nail in my garage. ;-)
