If you have the lemon law attorney on board already, just a call to the service adviser will go a long way. The biggest thing here is to remain calm and not just start beating drums every chance you get. You have to remember, the dealership doesn't know, I'm sure they are have calls into the Stelantis engineers and are waiting on them to get back to them. They might even be waiting for one to arrive to the dealer to look at it.
The dealer service department is your friend in cases like this. My wife has a 23 GC Overland that has some weird little glitches now and again. A year ago we had an issue where the rear seat HVAC panel was dead and the kids didn't tell us it was like that for a few weeks. I was driving and the odometer started flashing, it was a way for the computer to tell you something was wrong, but it wasn't so wrong that the vehicle needed to be disabled. We made an appointment to take it in, the service department tore half the Jeep apart and found a partially pinched wire in the center console. They fixed in, but they found out that some of the parts were one time use and if the process of taking it apart the parts are designed to break. Its a 2023, 2 years of this body style already and we took it in late 2024 for the issue. This was the first Jeep GC that this service department had taken apart. It took over a week because of waiting on parts, the Service writter was honest, but didn't call much, we had to keep checking in because they are usually busy beyond all belief. He would tell me that I have a note to call you and just couldn't get to it. He even showed us the notes on the paperwork.
The Service Depts don't get training, they don't get good information, most are understaffed and over worked. Training might be available, but they can't afford to loose the manpower for 2-5 days of training. I would agree that this is the case, my industry we have the same problem. Not enough employees, too much work, not enough time to train.
