In May 2015, "Argyle" encountered some technical problems and broke down mid-firth. What is usually a 35-minute crossing took 5 hours for her to finally berth in Rothesay, where she berthed bow-in and undertook repairs. In June 2015 her turbo charger had a problem that led to a massive amount of smoke coming out of her engine room. She diverted back to Wemyss Bay and berthed stern in while fire fighters, ambulance and police were at the scene. There were no casualties and "Argyle" was later towed to James Watt Dock in Greenock, and she was back in service a week later.
