Reliability report · 2021 Nissan Altima · Updated July 2026

The year the Altima settles down — out of the engine-bearing recall, with only two minor campaigns to check.

The 2021 Altima's complaint count falls to 67, roughly a third of the 2019's, and the mix is now ordinary: scattered electronics, engine, and AEB reports rather than a dominant failure. Crucially, the 2021 is out of the 25V437 VC-Turbo engine-bearing recall population (that campaign stops at 2020), so the year's most serious open item is gone.

What's left is light: a steering tie-rod recall carried over from 2020, and the backup-camera-harness recall. Both are free dealer fixes. A 2021 with those two campaigns confirmed complete is a genuinely settled version of this car — verify the recalls and drive it like any used sedan.

Canary status

Chirping

What that means: 67 federal complaints — a steep drop — and the 2021 sits outside the VC-Turbo engine-bearing recall that shadows the 2019–2020 cars. Two recalls remain, both quick free fixes. This is where the gen-6 Altima becomes an ordinary used car rather than a redesign-year gamble.

Tie-rod ball-joint recall (21V138)

major

Recall 21V138 covers 2020–2021 Altimas whose tie-rod ball-joint fastener may not have been tightened properly; the ball joint could detach from the steering knuckle and cause a loss of steering control. The free remedy tightens or replaces the left and right fasteners. It's the most serious open item on the 2021 — a steering-safety fix — so confirm it's closed by VIN and note any looseness or clunk in the steering on the test drive.

Backup-camera harness recall (23V628)moderate

Recall 23V628 (2019–2021 Altima) covers camera-harness damage that can distort or lose the rear image — a rear-visibility standard violation. Dealers inspect and replace the camera or harness, or re-route and tape it, free. Mechanics tie the striping and white-screen complaints to trunk-lid harness wiring that bends and breaks. Test the camera in several lighting conditions and run the VIN.

What you no longer worry aboutminor

For clarity, the 2021 is outside the population for the 25V437 VC-Turbo engine-bearing recall (2019–2020) — the fire-risk engine campaign that shadows the launch-year cars does not apply here, because the 2021 Altima moved away from the 2.0L VC-Turbo. It's also past the two 2019 fuel-system recalls, the 2019 brake-switch recall, and the rear-glass recall. What remains is the ordinary gen-6 checklist: AEB false-braking (a healthy battery plus clean sensors and a software update is the dealer fix) and the same Jatco CVT (a continuously variable transmission) that appears across the generation but generates far fewer complaints here than on the gen-5 cars.

AEB false-braking and electronicsminor

The small 2021 complaint file skews toward electronics and driver-assist: automatic emergency braking (AEB — the obstacle-braking system) activating with nothing ahead, backup-camera oddities, and occasional battery/BCM (body control module) gremlins. These are annoyance-grade at 2021 volumes. The AEB fix path is a healthy battery, clean radar sensors, and a software or ECM (engine control module) update. Test the ADAS suite and confirm the battery is fresh before reading too much into an electronic warning.

The dividing line is the recall list: after 2020, the fire-risk engine campaign no longer applies.
