This is DAVE, I have a 2020 ram limited eco diesel. I have about 9000 miles, taken 3 cross country trips. The truck has formed remarkable, 30 miles a gallon at speeds up 75 to 80 miles an hour. I would love to hear from someone about their’s and their performance. I have started experiencing problems with my truck not starting. The remote is not connecting and if I manually turn on the headlights I received one left headlight and one rear tail light and none of the dash lights or radio or restart button or anything works. It’s happened about three times and I got it to start after disconnecting and connecting the battery. Well today was the last straw I couldn’t get it to start going over the battery and all I called the tow truck and it didn’t show up so I tried the battery again and it started. Can anybody explain why. I am kind of a mechanic my last truck I had for 15 years and never had it in the shop it was 2006 Dodge Ram 5.9 Diesel.

Welcome Dave!

I'd suspect a bad ground connection and/or a bad battery. Erratic voltage can cause computers to do bizarre things.

Follow the negative cable from the battery to the body. Try snugging the bolt or even disconnecting it and cleaning things up good with a wire brush and then reattaching it.

Sounds like a dealer visit. Grounds etc... Hope it is fixed soon.
