The loudest Altima year in our data — buyable only with documented transmission history and expired-warranty eyes open.

Recall 16V244 covers a front-passenger Occupant Classification System — the seat sensor that decides whether to arm the passenger airbag — that could misread an adult as a child or empty seat and disable the airbag in a crash. It swept a huge range of Nissan and Infiniti models including 2013–2016 Altima; the fix is a free reprogram of the airbag and OCS control units. This is why the 2016 complaint file carries a large AIR BAGS cluster — much of it is recall activity, not a separate defect. Verify by VIN that the reprogram was done.

Two door/latch safety recalls apply. 20V315 (2013–2018 Altima): the secondary hood latch can corrode and stick open, so if the primary latch is released the hood could fly up while driving — the fix adds a stronger release spring and a warning label. 17V040, with its follow-up re-remedy 18V915 (2015–2017 Altima): a mis-routed rear-door latch cable can let a rear door pop open when the window is lowered. Both are free dealer fixes; on a used car the only question is whether they were completed, so run the VIN.

Beyond recalls, Nissan quietly extended coverage on a few 2016-era parts. The rear oxygen sensor emission warranty was extended to 20 years/200,000 miles for 2013–2016 Altimas (short-to-ground condition). Separately, a class-action Voluntary Service Campaign covered halogen-headlamp delamination (dimming low beams) on 2013–2018 Altimas with a 3-year, 6-years-total warranty extension. Neither is a safety recall, but both can mean a free repair if the symptoms show — ask the dealer to check eligibility by VIN.
