HELP 2016 Crosstrek Engine trouble
I have a 2016 Subaru Crosstrek with a manual transmission having engine problems. I am looking for help on where to start to try to fix it, as I recently (in the last month) have replaced the alternator (believe it may be a refurbed new to the car alternator, but not 100 %), replaced the battery, and the brakes.
symptoms: randomly dying- I'll be driving, the traction light will come on followed by the slippage and hill lights, sometimes the brake light, and then the power steering light. I usually am pulling over at this point as the steering will start to feel weird and then go out. usually at this point the car will be difficult to start (needing a jump) or maintain an idle without rev and die.
I thought I fixed it by replacing the alternator and the battery (replaced July 18), but it did it again today for the first time in a few weeks and I have been driving it since it was replaced without issue. I don't drive super far, within 50 miles of home and I don't drive often, maybe 2-3 times a week, less than hour trips.
I am fully charging the battery and taking it in to be stress tested to make sure it isn't a bad battery, but beyond that I'm at a loss at where to even start, I am not mechanically inclined in the slightest so looking for recommendations on a starting point of possible issues to look at as I'm on a budget.
