This bulletin refers to a possible power steering fluid leak at the inlet/outlet pipe at the steering gear connection. Buick models affected include 2011-2012 Regal built after Dec. 31, 2010, and 2011-2012 LaCrosse equipped with engine RPO LLT and built after Dec. 31, 2010.
Proceed with this bulletin only if the customer has commented about this concern and the PIE number is listed in the Global Warranty management/Investigate History link (GWM/IVH). If the customer has not commented about this condition or the EI does not show in GWM/IVH, disregard the PI and proceed with diagnostics found in published service information. This is not a recall. Refer to Service Bulletin 04-00-89-053D for more details on the use of Engineering Information Pis.
Some customers may comment that power steering fluid is leaking from the vehicle. Upon inspection the technician may find power steering fluid in the area round the steering gear where the power steering inlet and outlet pipes connect to the gear housing.
GM is attempting to determine the root cause of the leak. Engineering has a need to gather information on vehicles prior to repair that may exhibit this condition. As a result, this information will be used to “root cause” the customer’s concern and develop a field fix.
CAUTION: Do not clean using brake cleaner or other reactive solvents as these solvents can damage rubber gaskets, seals and bushings.
Use the following steps to identify the source of the leak. Do not perform any corrective measures before talking with one of the engineers listed below.
