The hazard
Issue: On certain vehicles, the connecting rods and/or crankshaft components may not have been manufactured properly. As a result, the engine could make abnormal noises and a warning light may turn on. If you continue to drive the vehicle with these symptoms, the engine could fail. Note: This recall only affects certain vehicles equipped with a 6.2 L V8 gas engine. Safety Risk: An engine failure could cause a sudden loss of power to the wheels and increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and advise you to take your vehicle to inspect and, if necessary, repair or replace the engine. For vehicles that pass the engine inspection, the dealer will replace the oil with a higher viscosity oil, install a new oil fill cap, replace the oil filter, and add an insert to the owner's manual.
