The same issue has just happened to me. It's a 2021 defender xmr. I do not have any aftermarket lights or radio. Checked the connections and seems to be good. I've had nothing but bad luck with this machine and not ever hard on the machine. In the past 3 months hanger bearing,main drive line bent and dealership can't explain how or why as there were not scrape marks on drive line, front drive line fell off, speedo falling off. Tired of having to put money into a machine every time we take it out. Yes the machine is back at the dealership for the smart lock system. If any one can help and have me try something else out I'd appreciate it as would like to still ride. Thanks for your times and inputs
