I got a secondhand 2019 Corolla SE with the CVT and it has this subtle shudder or vibration that's bugging me. It happens consistently when I'm accelerating from a stop, right in that low-speed range, probably around 20-30 km/h. It feels like the car is briefly stumbling or shaking before it smooths out. It's not a violent jerk or anything, just a quick little shimmy. I've heard some people talk about CVT behavior, so I'm not sure if this is normal or something I should be worried about. Has anyone else experienced this with their 2019 SE? Which things should I check to rule out any issues?
