Battery saver mode keeps coming on, I have a 2016 Ram 1500. Radio display will not come on sometimes. While driving on the Freeway one day just completely lost power no battery saver lights had started at this time. Then one day it just completely died when slowing at a light (my SIL driving it) and was able to pull into a gas station but ended up having to have it towed home. So far we have replaced the battery and alternator 2 times each. Just tried to reset the PCM and battery saver light back on and I anticipate it just randomly dying if I drive it. I tried searching the threads but did not find an answer for this issue. I have no additional items installed that would increase the load on the battery, it started before it even began to get cold and still not that cold here in Texas only been down to 40 so far this year. Any help would be extremely appreciated as my other car was just totalled and I need my truck. Thank you!

 

What does you volt gauge have to say with engine running at idle?

 

did you ever figure out what was going on? my ex is having the same issue. has a 2017 dodge ram 1500 rebel. his radio button won't work sometimes. was not starting. today did not start at all and said battery saver mode.
