NHTSA Complaint #11684684 — 2018 JEEP WRANGLER

I have brought my vehicle in for 3 time for the dealership to take a look at Europe messages I have received. It is currently with them right now.as the start stop function is now not working. This happened while in the dealers possession and was working normally prior to me being it into the dealership. They said they repaired a vacuum leak. After the apportionment I noticed the start stop function wasn’t working and it said battery charging. I took my vehicle on a long drive to charge the auxiliary battery, but nothing changed. I brought the car back to the dealership and they are now saying they are not responsible as a battery can drain at any time. I have asked for dates on their OBD scans but they either do not have them or are unwilling to provide them to me. I asked what systems the auxiliary battery affects other than the start stop function. They told me seat belts, dash lighting and obviously emission because the vehicle will not start and stop the way it is supposed to, and continues to run while sitting at a light or stopped in traffic. I am currently waiting on results regarding the start stop function.
