Service bulletin IB21-X-002A
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.

| WB23-X-001 | 2023-11-06. Service bulletin. This bulletin provides information with regards to the Isuzu Commercial Vehicle (CV) Service Policies and Procedures Manual (SPPM). The Isuzu CV SPPM (sections 2.15 and 2.16) provides detailed procedures related to vehicle storage up to and beyond 30 days. Performing these required procedures at the specified intervals will properly maintain vehicles until they are retailed. Failure to follow the procedures outlined may result in repairs and additional costs that could have been avoided. We are providing dealers with this brief overview of the recommended procedures as a reminder to maintain older inventory. Failures resulting from improper, or lack of, storage procedures are not covered under the vehicle factory warranty. |

| CB23H001 | 2023-02-03. Service bulletin. Isuzu Motors Limited has decided that a defect, which relates to motor vehicle safety, exists in certain 2022-2023MY Isuzu N-Series Diesel Vehicles produced after 7/26/2021 with RPO Code EM2 or EL5 (200" or 212" respectively) Wheelbase Factory Modifications. When the subject vehicles were modified to extend the frame, the Anti-lock Brake System (ABS) module was not recalibrated to account for the different inputs from the vehicle resulting from the stretched frame. Therefore, when driving in a curve, the Electronic Stability Control (ESC) system, working together with the ABS, may react prematurely or be delayed in reacting, therefore increasing the risk of a crash. If the vehicle is equipped with the optional Advanced Driver Assistance System (ADAS), the ADAS camera was also not recalibrated to account for the different inputs from the vehicle resulting from the stretched frame. Therefore, when driving in a curve with the optional ADAS system activated, the Automatic Emergency Braking System (AEBS) and its accompanying warning light may be delayed in reacting and illuminating, also increasing the risk of a crash. |
