While driving down the interstate, I lost the radio and some warning lights came on the dash. Soon after that I lost all gauges. We left it running the whole time till we got home. Once I shut it off, it wouldn’t start. I removed the negative battery cable and reattached it. It still didn’t start. After I let it sit for an hour or two, it started and I could get it into my garage. Then it didn’t start again. It started the next morning, so we took it to the local dealer. Everything was working, gauges & radio. The dealer ran all the test and said there was nothing wrong with it. Now 2 weeks later on another trip it did it again. Battery less then a year old. I have a video of the dash if that would help out. We like this Acadia and would like to get this resolved.
