Service bulletin S2102000004 REV.D

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

9100897Rev12026-09-17. Service bulletin. Qudra Lift Reman Compressor Excessive Repairs on Quadra Lift Reman Compressors Part Numbers: 68041137AF / R8572790AA / 68087233AA / 52124932AE / 52124934AE / 68064343AC Purpose The Star Parts Catalog has been updated to support component-level repair of the Quadra-Lift air suspension system. Replace only the component confirmed failed through diagnostics. Avoid replacing the complete assembly when an individual service component can correct the concern. Available Service Components Part Number Description R8572790AA Air Suspension Compressor 68087233AA Air Suspension Valve Block 52124932AE Front Air Suspension Hose Assembly 52124934AE Rear Air Suspension Hose Assembly 68064343AC Air Suspension Reservoir 68087240AA Temperature Sensor 68041137AF Compressor Assembly Diagnostic Decision Tree Customer Complaint: Service Air Suspension Message / Sagging / Unable to Adjust Ride Height / Compressor Running Continuously. Step 1: Retrieve and record all DTCs. C15D9 (Low Air Mass): Perform air mass test, complete system fill, leak-down test, and leak source identification before compressor replacement. C15A1 (Unable to Obtain Desired Ride Height): Verify ride height, perform leak-down test, inspect valve block, air lines, and air springs. C1562-98 (Over Temperature): Inspect for excessive compressor run time, leaks, low air mass, and restrictions before condemning the compressor. If a leak is found, repair the leak and verify operation before replacing the compressor. If no leak is found, perform compressor functional evaluation. If moisture is in the lines and valve block, then evacuate or replace lines. Only replace the compressor when a defect is verified (internal leak, failed solenoid, weak output, seized motor, failed functional test, or electrical failure). Service Component Selection Guide Verified Root Cause Recommended Repair Compressor Internal Failure Replace Compressor Valve Block Failure Replace Valve Block Air Line Leak Replace Air Line Air Spring Leak Replace Air Spring Temperature Sensor Failure Replace Temperature Sensor Technician Reminder Replace only the component confirmed failed through diagnostics. In many cases, compressor replacement is not required when the root cause is an air leak, valve block issue, airline concern, or sensor fault.

9100811 Rev 42026-07-02. Service bulletin. Clunking when going over bumps, potholes, or turns. During diagnosis dealers may find rubber separating from the bushing on the handling link (SOL S2102000004 Rev C. for reference). This is normal and most likely is not attributed to the noise. Please follow normal diagnosis and ensure all tie-rod and ball joints are properly torqued and if worn, replace. If diagnosis leads to lower control arm replacement, the tension link(s) should be replaced first then test driven to ensure noise has disappeared before any handling link replacements.
