| 23-BD-002H | 2023-02-02. Service bulletin. VISIBILITY. This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation. |
| 22-GI-006H | 2022-08-05. Service bulletin. TIRES. Effective June 2, 2008, Federal Motor Vehicle Safety Standard 110 (FMVSS 110) established a threshold for correcting load carrying capacity information indicated on tire placards when vehicle weight has been increased before retail sale. This limit is the lesser of 1.5% of GVWR or 100 pounds. If the total added weight exceeds the lesser of the limit, a label must be added to the driver-side B-pillar within 25mm (1 inch) of the original tire placard. |
| 22-EM-010H | 2022-08-05. Service bulletin. ENGINE AND ENGINE COOLING. Follow the guidelines outlined in this bulletin to inspect and clean or replace certain components of the engine intake system accordingly during engine short block or sub-assembly replacement. |
| 22-AT-009H | 2022-08-05. Service bulletin. POWER TRAIN. If you are servicing an applicable vehicle with a “Check Engine” light on and one or more of the DTC listed on Page 2, follow the repair procedure and perform the diagnosis. If necessary, replace the High Flow electric oil pump (HF EOP) for HF EOP issues or the Dual Clutch Transmission for High Pressure electric oil pump (HP EOP) issues. |
| 218/231 amend | 2022-07-09. Service bulletin. STEERING. Certain vehicles may develop a bearing noise within the Motor Driven Power Steering (MDPS) column worm shaft assembly. If bearing noise is heard, follow the procedure in this bulletin to replace the worm shaft bearing. |
| 22-ST-007H | 2022-06-10. Service bulletin. STEERING; WHEELS; TIRES. N Vehicles are designed to maximize dynamic steering performance. In normal Ackerman steering geometry, the inner front tire turns more than the outer tire to help cornering in low-speed situations, i.e., parking lot maneuvering or sharp U-turns. N vehicles have a steering geometry optimized for performance driving. The N vehicle’s steering angle difference between the front wheels is reduced to enhance cornering performance. While this helps in high performance driving conditions, it can cause a higher level of tire side scrub that may create a slow shudder or vibration while turning at full steering lock. The feel is similar to turning a 4WD vehicle on dry asphalt when locked in 4WD. This shudder or vibration at parking lot speeds is normal, and no repairs should be performed. |
