R1T Service Park Brake System: Rivian SC to the Rescue

Rivian's Battery Estimation hasn't been the Most Accurate

Ever since I got my R1S, I've noticed that the battery range estimation hasn't been the best. Driving a Tesla for the last 3 years, it never had this kind of issue. During my last trip, the driver display shows 255mi remaining. My total trip (including 2 destinations) is 160mi so I believed I should be able to make it easily with a nice cushion. But the center display showed that I would arrive at first destination with 4mi remaining, and run out before the second destination! I knew this was false so I made the drive anyway, and arrived at second destination with 50mi remaining. If I understand correctly, the driver display range is simply the total rated range multiplied by SOC. That makes sense here, since my vehicle is rated for 370mi, 255mi is 68.9%. Coming from Tesla, I expect the number shown in the center display should account for factors like elevation, wind, traffic speed, etc. It's sad that my own mental estimation is better than Rivian's.

About 2 weeks ago, I had an issue with my beloved truck. So I was driving somewhere, parked and when I came back to go into drive, it flashed an error for the parking break, confused I then put it back into park. Tried to drive it again and the driving got disabled, service park break system error. It was my first time seeing such error, so i reached out to roadside (who by the way was phenomenal despite the ordeal) and they had to get the truck towed a couple hours away.

It got towed 3 hours to the service center. At the SC, they changed the drive heights and drive modes and I was eventually able to drive out of the road. They replaced a brake caliper but the problem recurred a few days later. This time they found a “soft set connector” that I guess was sending a bad signal. Since they fixed that (over a week) I haven't experienced any more problems.
