| PC864_PC854 2016 | 2022-11-12. Service bulletin. Turbo Actuator/High-Pressure Turbocharger Emission Warranty Extension Dealer Notification *****Dealer Announcement***** Nissan is committed to providing the highest levels of product quality and customer satisfaction. Therefore, Nissan is extending the emission warranty coverage on MY16 Titan XD Titan Turbo Actuator and High-Pressure Turbocharger to 10 Years or 150,000 miles, whichever occurs first. All other warranty terms, limitations, and conditions remain unchanged. Certain MY16 TITAN XD Diesel vehicles may experience issues with the Turbo Actuator or the High-Pressure Turbocharger. Over time, a solder crack may develop in the Turbo Actuator and/or carbon build-up is possible on the High-Pressure Turbocharger Compressor. The most likely conditions are a MIL-On with DTC P00AF and/or DTC P0299. These issues have no effect on vehicle safety, drivability, or fuel economy. There could be a decrease in performance if either condition were to occur. During the limited emission warranty extension period, owners are eligible for free replacement of the Turbo Actuator and High-Pressure Turbocharger if either is determined to be required by a Nissan trained technician. Owners of eligible vehicles will receive notification of this limited emission warranty extension during November 2022. ***** What Dealers Should Do ***** 1. Verify if vehicles are eligible for this Warranty Extension using the warranty extension page of Service Comm. 2. If a customer contacts the dealer with a Turbo Actuator or High-Pressure Turbocharger concern in an owned or leased vehicle, dealers should use the appropriate Technical Service Bulletin (TSB) to diagnose the root cause of the customer concern and identify the correct repair to resolve the customer concerns. |
