MG ZS my mg zs has an electrical issue.

Purchased used in January 2023 we had an issue. Had a long Journey (300+ miles) in march . We then didnt use the car for a few days. On next use found that the car wouldnt start Called out AA who said the battery was complely flat and the battery needed re-charging but was also recording a constant leak so changed So they replaced the battery. This got the car started. In June after anorhe 300+ mile journey we had a similar issue. AA towed me to the local MG dealer and the "module"? was replaced.
Auguat after a 400+ we have the radio issue again. Im now nervous about driving long distances. Has anyone else had this issue and resolved it?
