NHTSA Complaint #11529246 — 2015 BMW X5

Hi, here to report and solicit the assistance of the NHTSA to keep us safe. Thanks for everything you do! Our 2015 X5 (F15) diesel with the N57T motor had check engine light illuminate @~61k miles while driving normally at surface street speeds. This was within one-month of BMW performing its second mandatory EGR cooler recall (once in 2020 and again in 2023), NHTSA Campaign Number 21V907000 for fire potential. BMW dealership advised the check engine was due to fuel injector #6 failure. I asked the dealership if this (could) be related to the recent EGR replacement they performed and was advised no. The EGR cooler and fuel injectors are DIRECTLY related, so this was surprising. Furthermore, there are loads of forums online that point to this, plus two active, safety recalls for the N57T motors including fuel injectors and the high pressure fuel pump (HPFP). My biggest concern is BMWs HPFP Safety Recall SIB130121 affecting 2014-2018 N57T motors - issued on 7/29/21 (coincidently, my birthday;-) It's dangerous that BMW will not proactively replace the HPFP, even when experiencing ongoing fuel system issues (2x EGR coolers and now injectors) that may be tied to a potential HPFP failure. I won't wait for a catastrophic failure for what is an existing and well known recall. This is well documented across forums so it's concerning the NHTSA OK'd BMW's 10yr/120k mile "warranty extension" vs full, mandatory recall. BMW should be accountable and replace the HPFP before catastrophic power loss occurs at the wrong time/wrong place. When it does, I wanted to ensure this record was on file with you agency for insurance purposes. Second concern is for sib010919. Injector recall is for 2016&17 X5 diesels with the N57T engine, plus other diesel models from 2015/16&17. Online, deep-dive research revealed a gap, where the 2015 X5 diesels (again with the N57T motor) were excluded. While this is not a severe as the HPFP, can the agency advise why 2015's were missed? Many thanks!!
