The most common complaint from owners of the Chevrolet Silverado pickup truck is a loud thumping noise or vibration coming from the vehicle's steering column, according to CarComplaints.com. Other common complaints include excessive oil consumption and excessive engine noise.
The 2004 Chevrolet Silverado has the most complaints of all model years in the CarComplaints.com database as of June 2015, largely due to issues with the vehicle's steering column. Owners that report this issue are unsure of the underlying cause, though many claim Chevrolet dealers attempt to re-lubricate the steering racks of their trucks to no avail. Some owners report that dealers have opted to replace the vehicle's steering rod, though this does not always solve the issue either.
Almost all Silverado models produced from the early 2000s onward have exhibited some degree of excessive oil consumption according to owners, though the 2009 model year has the most complaints overall. Problems with excessive oil consumption have also been linked with knocking noises from the engine compartment that may be due to insufficient oil pressure rather than traditional engine knocking, which is caused by prematurely detonating fuel in the engine. Several owners speculate that the active fuel management system used in more recent Silverado engines may contribute to these issues, and some have reported that disabling this feature has improved the oil consumption of their trucks.
