Known engine issues
Cooling systemEarly versions of this engine were equipped with short-lived cooling system pipes that often burst, but later plastic was replaced with rubber and the problem went away. Also on the forum they often complain about the short-lived water pump, radiators and coolant expansion tank cap.
Oil consumptionCompared to its predecessors, B48 units are not as prone to oil consumption, but closer to 100,000 km the valve stem seals usually harden and consumption appears. Also worth noting are regular leaks from the oil filter housing, it needs to be monitored.
Floating idleFloating idle speed or regular appearance of lean mixture errors indicate failure of the fuel tank ventilation valve. But it is inexpensive.

Known issues and risks
Listed from most frequently reported, each with its source.
Fragility of cooling system pipes and connectors
Often reported
The B48 engine uses many plastic pipes, fittings, and connectors in the cooling circuit; premature breakage or hardening is reported after a few years, which can lead to coolant leaks, especially in older vehicles.

Oil leaks (gaskets/filter housing)
Often reported
Oil leaks from the oil filter housing gaskets, O-rings, and sealing points are reported on the B48 engine. Leaks may occur on average-mileage vehicles and typically require gasket replacement or realignment.
Engine Bay
Valve deposits (direct injection)
Often reported
The B48 engine is prone to carbon buildup on intake valves over time, which can lead to reduced performance and low-end torque loss.
Engine Internal
Injector / high-pressure fuel pump failures
Often reported
Injector or high-pressure fuel pump (HPFP) failures are reported on B48 engines; this can cause misfires, power loss, and check engine light illumination. These issues are often seen on medium-to-high mileage engines or after repeated thermal stress.
