I've reviewed a lot of threads about the baffled oil pan issue and they all seem to say this was only an issue with the GTs - that the 400s did not have baffles. Service records (from a Lotus dealership) for an oil change on a 2017 400 include the note "replaced flaps". Were there 2017 400s that had the baffled oil pan? Are there some other kinds of "flaps" on a 400 oil pan this could be referring to? Thanks.
