Owners have filed 42 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
Buyer takeaway: The 2015 Altima has significant electrical system instability—sudden power loss, lighting circuit failures, key fob glitches, and water intrusion are widespread and often unresolved even after repairs. Airbag and transmission failures also appear in this complaint cluster; get a pre-purchase electrical inspection from an independent shop and verify no hidden water damage under the dash.
The 2015 Nissan Altima electrical complaints span a wide failure range. Multiple owners report sudden, complete loss of electrical power or engine stall while driving—at highway speed, idle, or parking lots—without warning lights. One owner lost acceleration climbing a Pennsylvania highway, nearly hit by semis; another's car shut down three times during a single drive, locking brakes and steering. Repairs have included battery, alternator, O2 sensor, MAF sensor, and transmission software updates, yet failures recur.
Lighting failures dominate: headlights go dim or inoperable (some delaminated), fog lights fail, backup camera goes blank intermittently, and one owner's independent mechanic found the main fuse box overloaded at 35,000 miles and had to install a secondary box. Key fob and push-button start systems fail repeatedly—owners get "no key detected" or "wrong key" errors despite fresh batteries. Water leaks flood the driver-side cabin after rain, damaging under-dash electrics; one dealership acknowledged faulty firewall grommets as a known problem on 2013–2017 Altimas but denied warranty coverage.
Airbag warning lights come on repeatedly with no occupants in the passenger seat. One owner's airbags failed to deploy during a major crash. Transmission problems include judder and shaking; one owner replaced the transmission three times in eight months. Two owners report engine fires—one 20 minutes after an oil change, another while driving—with total engine compartment loss. Trunk auto-opens, hood pops open while driving, door latches fail, and one owner was trapped in a car with dead battery and no manual unlock in 100-degree heat.
