Watch out for blue smoke from the exhaust, which can be an indicator of burning oil.
• Suspension Components: Over time, suspension components like struts, shocks, and bushings can wear out. This can lead to a rougher ride, reduced handling, and unusual noises. Pay attention to how the car handles bumps and potholes. Replacing worn suspension parts can restore the car's ride quality and handling.

Maintenance Essentials: Keeping Your Altima in Top Shape
