On G90s equipped with the 3.3L twin-turbo V6, the original left-hand turbocharger oil feed pipe and hose assembly was manufactured from a material that becomes brittle after prolonged heat exposure and repeated heat/cool cycling. The pipe cracks and leaks pressurized engine oil d… Repairs typically run $0-$800. Severity: high.
Coolant weeping/leaks are frequently reported and seen by technicians on first-gen G90s — commonly from the water pump and thermostat housing on the 3.3T, plus O-ring/gasket seepage on the 5.0. Left unaddressed, slow coolant loss risks overheating and cylinder-head damage on the… Repairs typically run $350-$900. Severity: medium.

Root causes owners and dealers have found include sunroof frame/track attachment bolts that ba… Repairs typically run $300-$3,000. Severity: medium.
