The problem: These vehicles may have been built with a hose connection within the power-steering fluid cooler unit that’s missing a seal. If this is the case and the vehicle is driven, the power-steering system could run low or dry, resulting in difficult steering and possible damage to other parts of the system. Additionally, should the power-steering fluid find its way to an ignition point, such as a hot exhaust manifold, it could ignite, causing an under-hood fire.
Corrective action: On affected vehicles, GM will inspect the power-steering hoses on both gasoline- and diesel-powered vehicles. If the hoses are in good shape, dealers will replace the power-steering fluid cooler unit, reattach the hoses, fill the system and check for leaks.
Warranty info: Repairs will be covered under the provisions of the new-vehicle warranty.
What owners should do: Call your local dealer with your vehicle identification number to determine if your vehicle is involved in this service action. You can also call Chevrolet at 800-222-1020 or GMC at 800-462-8782. Reference TSB number 14608.
