The GM wet timing belt in the Trax is likely HNBR. GM learned from Ford's mistakes, engineering dexos oil to be compatible and provide cooling. The 1.2L engine has been in use 5 years with no widespread belt-related failures documented. GM's approach is holistic, treating oil as an active component, and they expect the belt to last 150,000 miles.

They see plenty of use in europe, another thing where maintenance is key. Haven't seen much as far as gm having issues. Don't think they'd be putting 15 year service intervals if they weren't confident they wouldn't be sued.
