Shudder at light throttle around 40 mph

RustGeekCommunity StarterNov 26, 20252024 Polestar 2 Long Range Dual MotorSacramento
2024 Polestar 2 Long Range Dual Motor, about 1,200 miles. I get a light shudder at steady throttle around 35–45 mph. If I accelerate harder or lift off, it goes away. Trying to figure out whether this sounds more like torque-converter behavior, engine misfire, or tires. Any data points from owners would help.

Log the conditions before you spend. Capture voltage while the 2024 Polestar 2 is actually failing — after it restarts you've lost the clue. You'll know quickly if you're on the wrong tree. On “shudder at light throttle around 40 mph,” that was the fork that mattered for me. This is from a 2024 Polestar 2 in Sacramento with 1,200 miles. Take it or leave it — that's what I'd do. I keep a notes app thread for this now.

If it were in my driveway, loaded-suspension checks on the 2024 Polestar 2 catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. Take it or leave it — that's what I'd do. I'd rather pay for diagnosis than a second guess-repair.

Ask what changed right before it started. If a shop can't duplicate it on the 2024 Polestar 2, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. If they can't show the line item, I assume it's hiding. Wrote this up on my lunch break.
