Shuddering Car

Hey! It’s me girl who has constant issues with her 2017 jeep renegade. That only has 87,000 miles on it :’). Anyways I took it in to a shop because while i would drive and be parked, it seemed to shudder/skip/stutter every 2 minutes or so. It got to the point where I was scared to even drive it. No lights or codes came up on the dashboard ofc so they just tried changing to spark plugs, clean the throttle and god knows whatever else. It seemed to fix the issue until 2 days ago it’s starting to shudder/skip/stutter but this time ONLY while braked/parked. So red lights and being parked is not a fun time. Again, there is nothing showing up on my dashboard. I just wanna know if anyone else has had this issue. I just got a brand new battery and brake job done prior as well. Waiting to get into the shop this upcoming thursday.
