Driving in Knoxville, TN, means experiencing hot summers, humid conditions, and unpredictable winters—all of which can impact your Nissan’s engine performance. Regular engine maintenance is key to ensuring your vehicle runs smoothly, avoiding costly repairs, and improving fuel efficiency.
At Ted Russell Nissan Service Department, we specialize in Nissan engine care, offering professional diagnostics and repairs tailored to Knoxville drivers. Below, we’ll highlight the most common signs your Nissan engine may need service and what you can do to keep your vehicle running in peak condition.
1. Check Engine Light is On
The check engine light is one of the most obvious indicators that something is wrong. Whether it’s a minor sensor issue or a more serious engine malfunction, ignoring this warning can lead to major damage. If your check engine light is flashing or stays on, visit Ted Russell Nissan’s Service Center for a diagnostic check.
2. Strange Noises from the Engine
Knocking, clicking, or grinding sounds coming from your engine can indicate internal damage, low oil levels, or worn-out components. Since Knoxville’s summer heat can cause oil to break down faster, scheduling regular oil changes is essential to preventing costly engine repairs.
3. Loss of Power or Rough Idling
If your Nissan struggles to accelerate, experiences rough idling, or hesitates when you press the gas, it could be due to a clogged fuel injector, faulty spark plugs, or a failing catalytic converter. These problems are common in stop-and-go city driving conditions, making routine engine tune-ups vital for Knoxville commuters.
4. Excessive Exhaust Smoke
If you notice blue, black, or white smoke coming from your exhaust, this could signal an oil leak, fuel system issue, or a coolant leak. Excessive smoke often means a failing head gasket or burning oil, which should be addressed immediately by a Nissan-certified technician.
5. Overheating Engine
Tennessee summers can push your cooling system to its limits, leading to engine overheating if coolant levels are low or if your radiator isn’t working properly. Overheating can result in severe damage, so be sure to check your coolant levels and bring your Nissan in for radiator service if you notice high engine temperatures.

6. Unusual Vibrations or Stalling
If your Nissan vibrates while idling or randomly stalls, it could indicate fuel system issues, faulty sensors, or ignition problems. Getting a fuel system inspection at Ted Russell Nissan Service Department can help restore performance and prevent engine misfires.

Most modern Nissan vehicles need synthetic oil changes every 5,000–7,500 miles. Check your owner’s manual for exact recommendations.

Most Nissan models use synthetic 0W-20 or 5W-30. Always check your owner’s manual for the correct specification.
6. What causes my Nissan to stall at stoplights?
Stalling could be due to a faulty mass airflow sensor, dirty throttle body, or fuel system issue. Having it inspected early can prevent further issues.

A ticking sound could mean low oil levels, worn lifters, or timing chain issues. It’s best to have it checked before serious damage occurs.
