    i was really suspect the alternator last night when i started the car with the interior light on and it basically turned off 3 times while the starter motor was firing

    You gotta chase it down like OP did when and if it makes it again. If it does, pull the belt, if it stops, you know its something belt driven with a bearing likely going down. Alternator, tensioner, AC compressor, etc.

    But if it doesnt make the noise, cruise on my man.

    my first thoughts would be that if it only happened at over 40 that its not going to be a belt or pulley but something that's moving at that speed. then again my mirage makes a lot of funny noises.

    Yep that's the culprit right there then eh? Well in any case it's good you know what the noise is now, no more mystery.

    If you have the manual transmission I would keep an eye on the starter issue acting up, like mine did. Grindy starter sound is the sign. I think the early builds, 2013 and 14 had glitchy starters. I got Mitsubishi to cover it under new car warranty---after much bickering.

    Talking about funny Mirage noises above, do you mean plastic dash rattles, and hatchback hatch rattles haha. Econobox but it's a nice car I think.

    No I would still trust an actual Mitsubishi part to replace what you have. I might trust an aftermarket exhaust, but I wouldn't for an alternator. To each their own of course. I'm looking at prices on Mitsubishi Parts Now.com for alternators - $849.75. That's for a new one that's stock.

    Here's the link for you Dirk
