The 2020 Sentra, which is the first year of the B18 generation, has a documented cluster of steering complaints. This includes issues like steering pull or drift, an off-center steering wheel, electric power-steering assist failure, steering noise, or warning lights. Eight crash-related complaints were reported, indicating a potential safety concern. Buyers should verify all recalls are performed, test drive at highway speeds, check the steering wheel is centered, and listen for low-speed noises.

Electrical system complaints are the second most common problem for the 2020 Sentra and the most common for the 2023 Sentra. These may include infotainment freezes, dashboard warning-light errors, battery-drain issues, or sensor/ADAS malfunctions. Consequences vary from cosmetic glitches to disabling driver-assist features. A pre-purchase inspection should check for software updates, battery health, and test all electrical functions.
