My 2016 MDX started acting up last night. The headlight tail lights flash like crazy and the interior speedometer dash is flashing also. I had unplugged the battery last night and once plugged back in the issue comes back. The car is able to crank and start and the issue goes away. Haven't driven it, but once you shut the car off it resume and flickers. I checked the battery and was around 12.6V off. Any thoughts? Some button or switch needs replacing? I can get a video recorded if needed.

 

Since it’s only happening when the car is off, does changing the headlight auto off delay to 0 change the behavior? I think the adjustment is in Driver's settings under Lighting Setup.
