Common Issues With A Used Nissan Sentra: Check your used Sentra candidate for any “check engine” lights or stored “trouble codes” with the help of a mechanic and a computer scan. Pay close attention to any codes and associated sluggish performance issues that could indicate a “plugged” catalytic converter or damaged pre-catalyst. Other signs of trouble here may include terrible smelling exhaust and burning oil.
On that note, checking the oil level and condition is highly advised. Oil should be light, golden brown in color, not burnt and black.
Check for the presence of any “low tire pressure” warnings, which could be caused by a well-known Tire Pressure Monitoring System (TPMS) issue. Some owners say this system is far from reliable, so ignore its warnings and check tire pressures by hand if you note any problems.
Performance issues that include “lugging” or “bogging” under light or moderate acceleration could be caused by a bad knock sensor, which may or may not be accompanied by a “check engine” light.
A scan of owner forums reveals no worrisome problems with the somewhat-unproven CVT transmission, though shoppers who can drive a manual are advised to go this route for the sake of long-term reliability and running costs.

Other checks should include tire and brake wear, and signs of alignment issues with the rear tires. The latter could be evidenced by uneven wear across the tire treads.
Finally, inspect the interior for any signs of unexpected wear to the seats, dash and panels, and avoid any model with excessive “performance” modifications made by its previous owners.
