The 2000 Nissan Sentra has 3 recalls, the most serious being two separate defects that can cause the engine to stall without warning while driving, raising the risk of a crash.
Both engine-stall concerns trace to the crank position sensor, which signals the engine's computer to keep the engine running. In one case, a faulty solder joint on the sensor's circuit board can interrupt that signal, causing the engine to lose power, fail to start, or shut off unexpectedly while in motion. The other affects vehicles with the 1.8-liter engine specifically, where a defective sensor can produce the same result: sudden engine cutoff while driving, sometimes preceded by the "service engine soon" warning light or a noticeable drop in power. The third recall involves the engine control module box, where foam lining material releases sulfur gas as it ages. If any resistor inside the module has a cracked surface coating, that gas can corrode the resistor and impair the module's ability to manage engine and vehicle systems properly.
