Improperly Torqued Hub Bolts on R1S

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.

This is an old issue but still wanted to share a “known issue” story in case others run into to.

So apparently, there is a recurring issue with an improperly torqued hub bolt on R1S vehicles. Sounds similar to issues seen in connection with CV axle clunking. Mine occurred on front driver side. A grinding noise suddenly appeared when turning left. The improperly torqued bolt loosened enough to cause damage to brake rotor and pad and hub (all of which needed to be replaced) within 15 miles. Mine has been fixed some months back and it hasn't occurred again.

An additional information, R1S uses about 2 kW per mile in deep sand mode on highest suspension setting when driving in sand on the beach and moderately loaded.
