Weird electrical potential alternator issue. What’s going on?
Hello, I drive a 2017 Subaru Outback 3.7 L engine, it has about 108,500 miles. A couple of weeks ago while driving my whole dash just went blank, and so I took it in and learned I needed a new alternator. I got that replaced and It was working fine afterwards, however for about once a week since my engine will just randomly start revving, followed by brake light, abs light, and swerve then up, then my power steering goes out then the electrical goes out as well. Usually this will happen if it’s super hot outside, and if Im using AC. If I stop driving it for an hour or two it’ll start working again.
I have taken it back to the shop, let them keep the car and nothing happened. This same issue has happened at least once a week for the last 3 weeks, and has just been super inconvenient and annoying. As I’ve had to just drop off my car in random places, wait an hour or two, then drive back, or get a ride. Seeing if anyone has had a similar issue and how to potentially fix or to just bring back to the shop.
