Stuttering on acceleration

[Rrickjr24]

Good Morning
Was wondering if any of you experienced this?

I purchased a 2024 Bronco Sport a couple months ago. Every time I accelerate from a stop, the car starts to stutter until I reach about 30mph. Took it to the dealer and replicated the issue and they had it for 3 days. They told me they couldn’t find anything wrong but decided to flash the transmission module and said it would need to relearn my driving habits. It’s been about 800 miles and the car still does it. I’m going to take it back to the dealer when I drive it a 1000 miles but was hoping for some information to share with them.

It does seem like a common problem, I’ve seen many posts on the topic but apparently no solutions that don’t involve an engine tune product (lots of posts on that topic too)

Some owners have said 91 octane can help especially in hot weather but doesn’t appear to be universal agreement on that

Some owners say to use Sport mode, some say issue goes away in ECO mode

Torque converter issue?
