You'd be surprised, I was in Georgia clay mud and what I can tell you is that in mud, the Sierra may have a slight advantage from the 4 wheel steer. I didn't think much of it, until I saw how much better control I had and the small amount of rear wiggle you have from steering actually breaks...

I sold my R1T quad for a Sierra Denali EV and you can clearly see that GM is a well established machine. R1T is like a VW GTI as the Denali is a Mercedes S series... different, but I prefer the Mercedes where I am in life. Also Sierra at full battery says 480 miles and I get 480 at 75MPH... I...

I go pick up on Monday but they did message that it was a solenoid, front end module, and a front cowl. Have no idea what this means so will have to wait to talk to them. But sounds it’s all electrical, which is somewhat concerning. I don’t know what the failure rate is, but couldn’t find any...

Thank you. We need to make sure these issues are brought to life to make sure these were just one offs... but I will tell you the connecting relationship between these two incidences is the battery. All the error lights come up after fast chargers and go away after a full restart...

the other post was mine. Yes - I can't trust this vehicle and will find a way for Vivian to take it back. Mine has been to the shop 12 times. Losing brakes at highways speeds with your daughter in the car is scary. My wife has an R1S and only minor issues but she knows about the emergency brakes...

I think in my case it was completely a software issue because the brake pedal was locked and couldn't be pressed. After the reset the brakes worked as normal. During the software glitch the regen also stopped working. If you look at the screen shot, I'm coasting and zero regain. all battery and...

Update: have been patient with Rivian thus far. They called saturday to let me know they identified that the brake solenoid boost was the issue. I told them “no” i’m not taking BS anymore. The issue was a software glitch. Unless they tell me that the brake solenoid causes all the error lights to...

update: It's been two weeks since they took it. I've received a couple of calls per week. added complaint to NHSA. I hope they get to the bottom of the root cause for all of us to know what can lead to this issue.

After doing a soft and hard reset, everything was working ok. Even with the trailer. So it looks like it was an electrical glitch - very dangerous one though.

After this event, i’m a strong believer that there are things in cars that should never change for consistency… hazzard light button, horn, emergency brake, and even the door handle. This move to replace because they ”seem” like a better idea is practically not sound. Emergency brakes have been...

Cayenne. And it’s sporting clays. It’s like golf with shotguns, but instead of golf carts, you have off road side by sides loaded with shotguns and ammo :)

Agree. Do need to find the cause though because the error messages usually come after a fast charge. If it’s related to battery heat management, and the errors are treated as glitches, but something bigger is underlaying, needs to get solved for everyone.

Some more data that helps with everyone that is being critical of the situation: 1. the trailer is a karavan 5x10: 800 lbs 2. Item towed is a teryx4: 1642 lbs Total towed weight: 2,442 lbs (Rivian computer jumps between 3k, 3.5k and 4K on what it estimates as weight, but the formal weight...

Quick update-: Rivian has towed the car away.

This is the last one. I love the vehicle and suspension issues, half shafts, etc… i can deal with. Failure in braking i can’t So after this i’m done. Speed limit in my state when towing in the highway i was on is 70 MPH. If you look at the consumption, i was at the high end of my trip. I was...
