I've been having this intermittent issue with my XT6 where the infotainment screen will randomly freeze or go black for a few seconds, and sometimes the parking sensors will start beeping for no reason when there's nothing around the car. It's not a massive problem in the sense that the car still drives fine, but it's really annoying and it makes me worry that there might be a deeper electrical issue that could get worse over time. I've taken it to the dealer once already and they said they couldn't find any fault codes and basically just told me to monitor it, which was not exactly helpful considering I paid them a diagnostic fee for that non-answer. I'm pretty sure this is one of those issues that needs someone who really knows Cadillacs and understands the specific electrical systems they use, rather than a general mechanic who might not be familiar with the quirks. I live in Khalifa City so I'm hoping to find a workshop nearby that actually specialises in these cars and can properly diagnose what's going on. I've been looking for a place that offers Certified Cadillac Service in Khalifa City because I want someone who has the right equipment and training to track down these intermittent electrical faults without just guessing. Has anyone here had similar electrical issues with their Cadillac and found a good specialist who actually managed to sort it out? I'd really appreciate any recommendations because this is driving me crazy.
