2012 MITSUBISHI LANCER Engine Problems

I own a 2012 Mitsubishi Lancer and I have been experiencing issues with the engine. The check engine light comes on constantly then disappears for about 2 weeks and then comes back soon after. This has been a ongoing thing since i got the car a few months ago. Also, my battery light will come on (with noise and notice) then quickly turn off and not come back on. This happens on and off also. I did some research and I believe it is a belt issue.

Approximately May, 2020, prior to getting the vehicle inspected, code P0420 indicated a faulty catalytic converters. At this time, the vehicle had an estimated 170,000 miles on it so I replaced the catalytic converter, not thinking much of it. The we’re not further issues for about a year until June, 2021, when, once again, the computer started reading a P0420 code. Having only 30,000 - 40,000 miles, on it, and seeing no leaks in the exhaust or anything else that should cause a catalytic converter to go bad prematurely, there is clearly something else causing this issue.

NHTSA safety report 06/2021 — while driving approximately 45-50 mph, the ABS warning light and traction control light suddenly came on the display so I reduced speed and had planned to proceed to the next service station which was approximately 1.5 miles away. However, when I was approximately 1/2 mile from the station the engine stalled, the vehicle slightly jerked, and the the engine died. At this point, I shifted into neutral and cruised a couple hundred feet to a safe pull-off point. Upon inspection of the vehicle, the battery was completely dead and would not hold a charge when jumped. This prompted me to check the alternator where I noticed the loose belt and broken tensioner which I had repaired at my own expense the following day.
