Alright, let's get real. No car is perfect, and the 2018 Nissan Sentra SV is no exception. While the engine is generally reliable, some common issues can pop up.

Another problem area can be the catalytic converter. Over time, these can become clogged or fail, leading to reduced performance and increased emissions.
