Hi,

Recently my Max started to behave strangely. While driving down the road (it was raining) the wipers which were set to intermittent would wipe across the windshield super fast. Also, a popping noice could be heard coming from the speakers (radio was on) only when I accelerated?!
I shut down the car and a minute later restarted it, this time it was fine for about 5 minutes and the issues came back. Other than the two items I mentioned above, no other issues were noted.

A couple of weeks ago I replaced my antenna mast, otherwise no other work was done to the car.

Could it be a sporadic grounding problem (only when I accelerate)?

Any ideas???
