Shudder at light throttle around 40 mph

Ask what changed right before it started. Write temp, speed, and in-gear vs coast when the 2024 Rivian R1S does it — then decide on parts. You'll know quickly if you're on the wrong tree. The universe charges extra for guessing. This is the version I'd tell a friend.

Ask what changed right before it started. Loaded-suspension checks on the 2024 Rivian R1S catch play that a wheels-hanging inspection misses. That's the branch I'd chase this week. Monthly payment math is how wallets disappear. That's my plan before I call anyone.

I wouldn't throw parts yet. Write temp, speed, and in-gear vs coast when the 2024 Rivian R1S does it — then decide on parts. Don't erase codes until someone who can help has seen them. This is from a 2024 Rivian R1S in Charlotte. Time, temperature, and whether it's in gear are the notes that actually help a shop. Not driving it hard until I know more.

Log the conditions before you spend. Get a real battery/charging test on the 2024 Rivian R1S, not just resting voltage, before blaming a module. If the cheap test changes it, stop and reassess. On “shudder at light throttle around 40 mph,” that was the fork that mattered for me. Monthly payment math is how wallets disappear. I'll update if anything new shows up.

Start with the test that can prove you wrong. A pressure test beats staring at a dry driveway if the 2024 Rivian R1S is losing coolant with no puddle. Save the big job until that test fails. Parts cannon is a personality type I try to avoid. This is me being the wet blanket on purpose.
