I purchased A 2024 SUT with off road package. I asked dealer to change wheels and tires to 22". I don't go off road either. I like the look of the 22" and they get better range from battery.
There was no modifications necessary.
Same thing happened to me. I only used a level 2 Charger. It took 4 1/2 weeks to resolve. First 3 1/2 weeks they thought it was something else. Finally when they decided to replace the main battery, it took a week. Then another few days for an unrelated issue
