Earlier this week I was backing out of a gas station at night and my gauge cluster lights started flickering on and of. It stopped shortly after. Then tonight did it some more but usually under acceleration or breaking. Sometimes during gear changes. Any ideas??? Only thing I did differently around the same time as the symptoms started was having my phone charger and radar detector both plugged into the cigarette lighter with a dual plug splitter. Please help. It's gonna drive me crazy. Also I've been getting a brake lamp failure message even though all my lights are working fine.
