BMW warranty extension B010520
BMW filed this with NHTSA as a warranty extension dated Aug 15, 2025, received May 18, 2020, about the engine and engine cooling — 4 documents under this number. It names 10 model years (2016–2018). A warranty extension is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
