ive been dealing with my aftermarket warranty company(fidelity) for about a year now(currently at 72k in a 2015 mirage de) it was squealing at 1200-2200 rpm under load only. 3 mechanics(Mitsubishi) and the first warranty inspector determined it was the ac compressor clutch. the warranty guy would not authorize repair until it blew hot.
forward about 8 months, no ac, constant squeal, the belt has no teeth. new warranty guy says its only the belt.
you can see melted bits of teeth in the engine pulley.
it now squeals 2x as loud on first takeoff either forward or reverse, and ac on or off. it lasts about a minute until something catches.
anybody had similar issues so i can try to gather info for the dealer repair shop?
