Shudder at light throttle around 40 mph

If it were in my driveway, loaded-suspension checks on the 2025 Honda Civic catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. Happy to compare notes if your setup is different. I'd rather pay for diagnosis than a second guess-repair.

Intermittent stuff lies if you only catch it once. Swap the cheap/easy piece first on the 2025 Honda Civic and see if the fault moves. That's the branch I'd chase this week. On “shudder at light throttle around 40 mph,” that was the fork that mattered for me. Not gospel, but it saved me a headache. Climate here is different, so treat that as a local data point. No warning lights, which is why I'm documenting it.

I wouldn't throw parts yet. Two 2025 Honda Civics can feel identical and have different causes, so measure before you copy someone else's repair. If the cheap test changes it, stop and reassess. The universe charges extra for guessing. If this is nothing, great. I want that in data.

I'd want a measurement, not a hunch. Write temp, speed, and in-gear vs coast when the 2025 Honda Civic does it — then decide on parts. If the cheap test changes it, stop and reassess. Monthly payment math is how wallets disappear. I'd rather pay for diagnosis than a second guess-repair.
