Hey guys just wondering and after scrolling through couldn't find anyone else with a similar problem... But after may car has been running a while.... Seems that I lose power I can't get the car past 100km/hr on highway speeds (or freeway if you're from the US). Today finally got a check engine light plugged it in and states its a P0234 which is turbo overboost condition. Has anyone else had issues with the turbo on the vehicle. Mine is a '16 with 106k on it and has been serviced regularly.

This sounds like the wastegate is stuck shut, and your engine is de-rating. The derating protects the engine from immediate damage and encourages you to get the issue fixed.
Over pressure will provide a ton of excess power, until your head gasket blows.

Clear the fault as it may have been a one time problem.
