What Goes Wrong
Reported failures, each from a source listed below, as of October 7, 2026.
- Tire Review (May 2011) reports that Nissan warns against driving the Altima Hybrid after it runs out of fuel, because electric-only running quickly depletes the hybrid battery and may damage it. (tirereview.com: hybrid-service-nissan-altima, 2026-10-07)
- Tire Review reports that a low 12 V battery on the Altima Hybrid can set code P0603 (ECM power supply), usually a false code that can be cleared with a scan tool. (tirereview.com: hybrid-service-nissan-altima, 2026-10-07)
- Tire Review notes that the inlet duct for the hybrid battery cooling fan is on the rear package shelf and must not be blocked or covered. (tirereview.com: hybrid-service-nissan-altima, 2026-10-07)
Symptoms
- A weak 12 V battery can leave a stored P0603 code on the Altima Hybrid, per Tire Review. (tirereview.com: hybrid-service-nissan-altima, 2026-10-07)
