Known issues on the 2008 GL320. Steering leads the 20 owner complaints on the 2008 GL320 with six, then seats and engine at two apiece; 1 complaint reported a crash and 1 an injury. Its own two recalls cover brake booster corrosion from collected moisture, and owners of certain vehicles were told not to drive until a dealer inspected the booster. Separately, NHTSA filed three recalls against the 2008 GL-Class line: a power steering drive pin in certain vehicles that could snap and leave the wheel hard to turn, hitch welds on certain vehicles with a Flex-N-Gate hitch, and a crankshaft sensor on certain diesel vehicles whose internal wiring could separate and stall the engine for good. Steering gear, brake and sensor procedures with torque values follow.
