Dealer updated the Hummer EV to add Extract mode. Required new ride height sensors and a software update. Golling Buick/GMC also charged it up and washed it while it was there!

The update adds a forth setting, Extract, which can be used in Terrain mode. Speed is limited to 12 mph and the 4-wheel steering is WILD in Extract mode.

Pictures show Extract, Extended, Normal and Entry/Exit. (Pictures don't do it justice.)

4-wheel steering is WILD in Extract mode.

I imagine it's the same as setting up the "my mode" to have the steering in the off-road setting? Its really strange to have the rear be that responsive at speed.

Whats the last 4 of your vin? Some guys were saying theirs already has the updated sensors. Had a truck in the 7xxs but dont know how to tell what ones have the sensors or don’t. Havent had any come with the mode

Congrats on getting it updated! Totally agree the 4 wheel steering while up tall is pretty crazy. Hopefully your's stays good. Mine went up and down a few times and is not busted and stuck in normal.

Surprised the side rails do not raise up as well. Thought it was going to just the wheels staying low like on the H1.

Huh? the whole vehicle raises and lowers, including rock rails

Its the angle of the pictures... The rails go up with the body...

It is but doesn’t look like it because the lower portions are painted black, plus photo angles causing an illusion. You have to look at the tires and edges of rock sliders

I stand corrected. I see the rock sliders move up from the bottom of the wheel bolts to the top of the wheel bolts.
That said, if the truck really needed to get through rock territory, I would like to see the rock sliders retract to the bottom of the cab.

The Rock Sliders are just a bit lower than level with the bottom of the Hummer next to the battery, they are their to protect the side of the vehicle and "slide" on rocks.
You don't want them to retract...

Yeah, on the Rivian forums a few people have "rock gashes" on the bottom of the trucks from off roading, since they do not have the rock sliders. Defeats the purpose if they retract.

Mine quit working properly after a few times too. I'm getting the "Leveling System Unavailable" message, so the truck is back at Golling to work out the bugs. That's the downside of being an early adopter.

0181 It was a pretty early delivery...Feb '22.

Interesting.. not too many of us who have had the update work done and to hear yours 'gave out' after a few uses is definitely curious. Keep us posted what you hear from the shop please. Also, interesting you got VIN 0181 in Feb.. I got 0086 in May.

When my truck came into the dealership in late June in a threesome, mine was in the low 500's one was in the high 600's and one was below 080

Just saw a new owner in the supermarket parking lot this afternoon.. he's had his for a week and it was #689 he said.

Also for the Extract mode -- got a call from my service dept manager... GM HQ told him they have a new program for Extract (guessing me and @Snogoer arent the only 2 with issues). Service dept is booked solid this week so sometime next week I'll be taking her back in for the update to the update.

Picked mine up this evening; leveling system is working as it should for now. Service manager said GM engineers are aware of the issues so I suspect they are working on an update. Hopefully it's OTA because I'm going out of town for a couple weeks.

Just dropped mine off today for the extract mode update. We will see how it works tomorrow. I would expect they would NOT continue to do the updates if it were a big issue...... we will see.

Did you get any details about what they did? Was it an update to the update or just a reset of the leveling system (guessing meaning a fuse pulled and maybe a recalibrate procedure) but same software loaded?
