Sometimes I can get in my 2017 Denali pickup with 28,000 miles and put the ignition switch in the start position and nothing happens. The dash lights go out but the headlights don’t even dim. The headlights are on because the truck is inside the garage. This usually only happens after the truck has sat for a day and night or longer. The battery voltage remains above 12 volts. The local parts house checked the battery and it shows to be good. After I get it started by connecting a battery charger at 50 amps it does fine the rest of the day. I have cleaned the battery cables twice, moved the battery cables around while the ignition is in the start position with no luck. Since this seldom happens, the dealer can’t find the problem. It happened again this morning and I tried the remote start and the engine started right up. Later, I noticed the volt meter was reading lower than usual but returned to 14 volts after restarting the engine. Any one want to make an educated guess of what might fix it? Thanks
