While driving the vehicle down the highway, all the dash lights started lighting up and the gauges appeared to stall in a random place, then reset. The check engine/tire pressure/low fuel/etc. lights all lit up at the same time and the gauges appeared to be malfunctioning momentarily. Within 15 seconds, everything appeared to be operating normally again . It happened 2 times in about a minute. Weather was warm in the 70’s and air was on
Time to find a code reader.
You might be looking at a BCM that’s failing.
If the trouble keeps happening I suggest you have the alternator checked out or just replaced. The problem is most likely coming from it. But if the trouble isn’t happening when they check it then it will most likely check out okay.
