M276 3.5 V6
The M272's replacement from 2011: a cleaner, smoother 3.5 V6 with the timing chain moved to the front of the engine and no balance-shaft concern. The most trouble-free petrol in the range, carbon aside.

Engine and component issues
Rough cold idle, slow throttle response, misfires, gradual loss of low-end response. Direct injection puts no fuel over the intake valves, so crankcase vapour deposits bake on undisturbed.
Check: Not visible without a borescope. Treat it as a service item that's due unless there's a receipt. It's not a fault, it's an unbudgeted maintenance cost.
Chassis, gearbox and body issues aren't listed here. They depend on which car the engine is fitted to. Open a variant page for the merged list.
