The last year of the old body and the only one where a CVT warranty check is still worth making — on a late-built car the coverage may only just have run out.

Recall 21V135 covers all 2016–2019 Sentras: 807,376 vehicles, and the 2019 is the last year in the population. The brake-light switch can become contaminated so the circuit never closes and the brake lights do not illuminate when you press the pedal. Dealers replace the switch and add a protective grommet, free of charge; Nissan's code is PM971 and owner letters went out on 1 July 2022. A used-car reviewer covering the 2019 correctly identifies this as one of the model year's two recalls, which matches the federal record exactly. Check it physically and by VIN.

Recall 19V654 is a compliance recall across a wide range of 2018–2019 Nissan and Infiniti models including the Sentra. The back-up camera's display settings can be adjusted so the rear image is no longer shown, and the car keeps that setting the next time you select reverse, which puts it outside the federal rear-visibility standard. The remedy is a free software update. Because it is software, the camera can be working perfectly on your test drive and the recall can still be open on paper — the only way to know is a VIN check.

Electrical system is the most-used component tag in the recent 2019 filings, narrowly ahead of the transmission. A used-car channel covering this model year calls out corrosion at the battery terminals that cuts all power even when the battery itself is fully charged, and the federal file carries a matching run of no-start, warning-lights-everywhere and instrument-cluster complaints. This is cheap to investigate and cheap to fix compared with anything else on this car, but it overlaps with the driver-assist complaints below — a weak battery or a poor ground is a well-known cause of spurious safety-system warnings on modern Nissans, so it is worth ruling out first rather than last.

Forward-collision and automatic-emergency-braking complaints form the third-largest group in the 2019 file. AEB is automatic emergency braking, the system that applies the brakes for you if it believes a collision is imminent; FCW is the forward collision warning that comes first. Owners report the car braking or alarming for objects that are not in its path, and the warning light flashing with no stored fault. The usual fix path is a healthy battery, a clean and unobstructed radar and camera behind the windscreen and grille, and a software update — the same reprogramming approach Nissan later published bulletins for on the following generation. Not an expensive problem, but a genuinely irritating one to live with, so test it on a road with parked cars and roadside furniture rather than an empty motorway.
