How would you feel about this?
Jason, sorry to hear that you are disappointed. We performed an annual maintenance service for you (not just an oil change) according to Mercedes Benz guidlines.
Regretfully, there is a update that Mercedes Benz needs to perform for you because your vehicle has corrupted software. It should be a recall but because it's not a safety system they have not stepped up for their customers. My advise is that you call MBUSA and voice your displeasure with them.
I have attached the TSB for this particular issue from Mercedes Benz LI54.30-P-062219
If you wish to discuss the issue please call us and ask for me directly. Your satisfaction is our highest priority.
Telly, MBS Automotive
