- [08\-231\-26 REV. D](/bulletins/11038317.md), 2026-10-07, Service bulletin: SUSPENSION. Service Air Suspension Message Customers may experience the following: SYMPTOM: ● "Service Air Suspension" warning message displayed after manually changing the air suspension ride height using the Display Screen Module \(DSM\)."
- [9100924](/bulletins/11037600.md), 2026-09-30, Service bulletin: SUSPENSION; STEERING. EPS BSR with Steering input. Check the Strut bearings, Strut mounts, or similar suspension components prior to replacing Steering Gears. Previous customers have returned after EPS gear was replaced. Strut bearings are the most frequent cause of RU BSR complaints.
- [9100897Rev1](/bulletins/11037351.md), 2026-09-17, Service bulletin: SUSPENSION. 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.

Service Air Suspension Message Customers may experience the following: SYMPTOM: ● "Service Air Suspension" warning message after altering ride height using the digital buttons on the Display Screen Module \(DSM\).
- [02\-007\-26](/bulletins/11036350.md), 2026-08-26, Service bulletin: SUSPENSION; WHEELS. Front Wheel Bearing Click Noise Issue Customers may comment on the following: SYMPTOM: ● Single or multiple clicking noises from the front wheels during static or very low speed steering maneuvers \(left or right\). NOTE: The noise may also occur when driving slow over speed bumps, traversing uneven road surfaces, or entering or exiting an inclined area or driveway. This bulletin involves removing and retorquing the front hub to knuckle fasteners.

- [9100811 Rev 4](/bulletins/11034381.md), 2026-07-02, Service bulletin: SUSPENSION. 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.
