Infiniti USA Tak2018-12-03. Service bulletin. AIR BAGS. Infiniti USA Electronic Field Communication Subject: Takata Completion Objectives for Q3 INFINITI is continuing to ask its retailers to urgently help increase customer participation in the Takata recalls to help it achieve 100% customer recall participation for the following vehicles: ? 2001 I30 ? 2002-04 I35 ? 2003-08 FX ? 2002-03 QX4 ? 2006-10 M Sedan INFINITI expects to upload the next refreshed owner list to DBS within the next week. We will also be reassigning VINs to retailers based on information changes. We didn?t reassign any VINs in Q2 to avoid any mid-quarter objective impact. If VINs were repaired out of network, the retailer/region with the original assignment received credit for the repair. This is an extremely serious safety issue and INFINITI is taking significant and unprecedented steps to increase client recall participation but it needs retailer help to achieve its remedy goals. A separate communication will be released later this month informing regional personnel of the requirements for bonus payout in Q3 and Q2 results. The Q3 objective is based on the average number of repairs in Q2 multiplied by the number of service days in Q3 (Mon-Sat minus any holidays). Retailer engagement is critical with this effort. It is a company-wide responsibility to make it a priority to replace these dangerous airbag inflators in affected vehicles. Further, increasing recall participation represents significant gross profit opportunity for our retailers.
Infiniti USA Ret2018-12-03. Service bulletin. EQUIPMENT. Infiniti USA Electronic Field Communication Subject: Retailed Vehicle Open Campaign Report Lists Updated The lists for each retailer?s Retailed Vehicle Open Campaign Report has been updated today in DBS. We made our best effort to reassign vehicles to retailers based on the most recent owner information we received. The complexity of filtering out brokers (banks, salvage yards, and insurance companies) and reassigning VINs based on updated owner information affected over 123K records between INFINITI and Nissan, so we are unable to summarize the changes at a regional or retailer level. We suggest the retailers download their lists and have their outbound call centers compare information if necessary. If you have questions, please let us know. Additionally, we will have some enhancements coming in DBS effective November 17, 2018: Owner Data Updates (NNA side): 1. VIN, Campaign Code, and Source are the unique fields 2. Compare all fields except Remove Flag and Comments to see if there is a difference. a. If there is same VIN, Camp ID, and Source and all other fields are also the same then the record will be updated without changing Remove Flag and Comment field b. If there is same VIN, Camp ID, and Source and any other field is different, then the record will be inserted, in this case Remove Flag and Comment field will be blank as this is new record. The remove flag is being removed so the retailer will understand the information they previously flagged for removal has been updated and should be tried again before reapplying the removal flag. c. The retailer benefit of A & B above is duplicate records for the same VIN, Camp ID, and information source with the same customer contact information will no longer display in DBS on the Retailed Vehicle Open Campaign Report.
