Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This is a Technical Information Notice informing dealers and parts managers about possible causes after a customer complains that the engine will not start while using the remote start system.

The failure pattern owners describe
The dominant complaint in this cluster is a parts supply disaster tied to drive belt and pulley recalls. Between 2014 and 2018, owners who received recall notifications for campaigns 14V562000 and 18V069000 consistently found dealers without the necessary parts and no timeline for delivery. Owners called back repeatedly—some every two weeks—only to hear the parts were on national back order. Mitsubishi either didn't answer or couldn't help. One owner had the belts replaced during routine 60,000-mile maintenance before the recall was issued and was later denied reimbursement because the recall only covered free replacement if a failure had occurred.
Beyond the recall headache, owners also reported engine stalling (one at 111,668 miles with a faulty drive belt flange that went unrepaired), erratic idle at traffic lights that would cut the engine off until shifted to Park, a no-start condition requiring electronic timing and control system replacement, and exhaust fumes leaking into the cabin at 62,000 miles. None of these secondary issues were resolved at the dealer level, and manufacturer involvement was minimal.
