The redesign year — only buy one with the engine-bearing recall and the launch-year fixes documented.

The 2019 carries two separate fuel-delivery recalls. 18V922: a retainer clip connecting the low-pressure fuel tube to the high-pressure fuel pump may not be locked into position, which can cause a fuel leak (fire risk) or a disconnect that stalls the engine. 19V316 (2.5L front-wheel-drive cars): the fuel-pump lock ring may not be fully engaged, allowing a fuel leak. Both are free dealer repairs — inspection and, if needed, re-securing or replacing the component. On a used 2019, confirm both are closed by VIN before you trust the fuel system.

Recall 19V235 covers 2019 Altimas whose brake-switch bracket may be in the wrong location, keeping the brake switch active. That leaves the brake lights on when the pedal isn't pressed, and can let the shifter move out of Park without the brake pedal down — a roll-away risk — plus cruise-control and engine-start quirks. The fix is a free inspection and, if needed, a new brake pedal. Mechanics describe it as an easy fix; the point is confirming it was done.

Two distinct backup-camera recalls apply. 19V654: the display can be set so the rear image is hidden and stays hidden — a free software update. 23V628 (2019–2021 Altima): physical damage to the camera harness can distort or lose the rear image — dealers inspect and replace the camera or harness, or re-route and tape it, free. Mechanics tie the striping/white-screen complaints in the file to trunk-lid harness wiring that bends and breaks. Test the camera in several lighting conditions and run the VIN for both.

Recall 21V169 covers 2019–2020 Altimas (and some Titans) fitted with certain Continental tires that may have been over-cured in production — a sidewall break or belt/tread separation risk. Dealers inspect and replace affected tires free. If the original tires are long gone this is moot, but verify the VIN and check what's actually mounted.

Three gen-6 launch quirks to check. Automatic emergency braking (AEB — the system that brakes for an obstacle) can false-trigger; enough Nissan owners reported it that a class-action lawsuit was filed, and Nissan's dealer fix is a healthy battery plus clean radar sensors and a software or ECM update. A 2019 TSB (Technical Service Bulletin — dealer fix instructions) addresses a rear-end clunk over bumps, typically with new rear shocks under warranty. And on SR trims with 19-inch wheels, mounting the compact spare alongside three full-size 19s has overheated the all-wheel-drive system — carry a full-size spare or avoid the 19s. Test the ADAS suite, drive over bumps, and check the spare provisions.
