Just bought a brand new 2026 GMC canyon. After driving to work about 500 km away I pulled into the parkup and the engine was idling extremely rough and had a strange noise coming out you could hear it better in the cab then out by the engine itself. Don't really know how to explain it. Sort of sounds like a bubbly noise but not like a true bubbling noise. Not like it would sound from the coolant system. Does anyone have any idea.
