problem #1

Jan 012017

MKX 6 cyl 3.5L Fuel Inj

  • Automatic transmission
  • 70,000 miles

While I am driving, at 25 miles per hour in my neighborhood, or 45 mph through town, or 65 mph on the freeway, without any warning there occasionally be an EXTREMELY LOUD BANG!! I actually duck down and cover my head for fear a huge rock has come through the windshield. Or a double-barreled shotgun was aimed at my car, or a major jetliner had fallen out of the sky and landed on my roof. Only to look up and see no damage whatsoever, but the shrill, high pitched ring piercing my ears.

The radio won't respond, the gps won't respond, the heater or AC won't respond. The sound continues for as long as it takes to get to my destination. When I return to my car the next time, EVERYTHING WORKS FINE, and no high pitched ring. I have seen others' notes on this topic say it is the radio/speakers. This BANG occurs for me even when I am NOT using the radio or media. However, my cell phone auto connects each time I turn on the engine. I will today 8/31/22 disconnect my cell phone and see if the bluetooth makes this terrible connection. I will update this when I feel I have the answer to at least this issue.

But, I see no evidence that anyone has found a repair for this. Also, other notes have stated they think this is related to temperatures above 73 F degrees. I have experienced this BANG at all temperatures. The latest time it occurred while I was in the middle of a left hand turn through a busy intersection with off-work traffic in all lanes, I almost went into the ditch!! Please, someone, is there a fix?
