I have an 2002 Acura MDX. Ive had the car about a month now. A couple of weeks ago the VTM-4 Light began to come on. It wasnt on all the time. After I noticed that light coming on my Back subwoofer began to cut out everytime the bass hit. (Not sure if this helps at all). Just recently my Radio began to power off and on by itself. Even more recent almost all the lights flash on and off that are on the dash boear (Check Engine, Brake, Battery, ) and the guages keep resetting. It seems like the lights go crazy and the guages move when ever I press the brake. Ive recently had acura replace a "Altnator Sensor" that thought would fix the issue. The paperwork looks like the sensor was only supposed to fix a Wheel hub bearing issue and a speed sensor issue. Im not sure whats wrong at all this all started out of nowhere. Could I just need a new battery? None of this really effects the cards driving and the Shift indicator light never blinks. Please help ME.

Start with a check for trouble codes.

Have the alternator/charging system checked/tested.

Check for poor ground ciruits.

Have the battery and charging system tested. Also check the connections at the battery posts to make sure they're clean and tight.
