Salam, @Xulfiqar bhai. Have an Alto VXL AGS and I am facing random electrical restarts (dash lights appearing as they do on startup), head unit restarts, at times it feels like an ECU restart too (as I am in D, but after restarting it gives the same beep when it does if you put it in D without depressing break), so I gotta put it in N and then to D and then it works fine for the entire drive.
It's very random, can't figure out a pattern yet, only thing I have noticed is it usually happens just after my car's been parked for several hours (cold starts).
I have also noticed some random speedo light flickering, very low though, hard to notice unless you focus on it, when this happens headlights flicker/lower too (like a charge draw).
Tracker isn't installed, it was before, but the guy I purchased the car from had it removed of course before selling, mentioning this as I saw your reply on a similar thread.
What's the issue, how should I diagnose what's causing this?
