Spotting Engine Trouble Early: Common Signs for INFINITI Owners

Experiencing car engine issues? Learn how to spot common INFINITI engine problems like overheating, strange noises, and power loss. Schedule service at Ed Hicks INFINITI today.

Your INFINITI is designed for power, precision, and luxury. From the QX60’s commanding presence to the Q50’s dynamic performance, every INFINITI model is engineered for a smooth and exhilarating drive. But even the most advanced engines require care and attention. Over time, wear and tear can lead to car engine problems that, if left unchecked, may result in costly repairs.

Knowing the warning signs of engine trouble can help you address issues early and keep your vehicle performing at its best. So, how do you know if your engine is bad? Let’s explore the most common symptoms of engine problems and what might be causing them.

Warning Signs of Common Engine Problems

A check engine light is the most obvious sign that your INFINITI engine needs attention. While it could indicate something minor, like a loose gas cap, it can also signal more serious car engine issues that require professional diagnostics.

Here are other key indicators that your INFINITI’s engine might be in trouble:

1. Strange Noises from the Engine

INFINITI engines are built to run smoothly, so unusual sounds can indicate underlying problems, such as:

• Knocking or pinging: This could be caused by incorrect fuel combustion, which can damage your engine over time.
• Grinding or ticking: Worn-out timing chain components or low oil levels could be to blame.
• Hissing sounds: This may indicate a vacuum leak or coolant escaping from the engine.

2. Loss of Power or Sluggish Acceleration

Your INFINITI’s V6 or turbocharged engine is designed for responsive acceleration. If you notice hesitation, difficulty reaching higher speeds, or an overall lack of power, potential culprits include:

• A clogged fuel injector or weak fuel pump
• A failing mass airflow (MAF) sensor
• A problem with the throttle body or turbocharger (for turbocharged models)

3. Unusual Exhaust Smoke

Your INFINITI’s exhaust should be clean and barely noticeable. If you see smoke, the color can indicate different engine issues:

• Black smoke: The engine may be burning too much fuel due to a faulty sensor.
• White smoke: A coolant leak may indicate a blown head gasket.
• Blue smoke: Burning oil could mean worn piston rings or valve seals.

4. Decreased Fuel Efficiency

If you’re making more frequent stops at the gas station, your INFINITI may be suffering from fuel system issues. Possible causes include:

• A dirty air filter or fuel injector, which can disrupt the air-fuel mixture
• A failing oxygen sensor, leading to inefficient fuel combustion
• A problem with the turbo system (for turbocharged models)

5. Overheating Engine

If your INFINITI is running hotter than usual, it could indicate a cooling system failure. Overheating can cause major engine damage, including warped cylinders and cracked gaskets. Common causes include:

• A failing water pump or radiator
• Low coolant levels due to a leak in the system
• A broken thermostat, preventing proper temperature regulation

5 Common Causes of INFINITI Engine Problems

Understanding the root causes of car engine issues can help prevent more extensive damage. Here are the most common reasons vehicles like your INFINITI might have engine issues. 

1. Low or Dirty Engine Oil

Your INFINITI engine needs clean, high-quality synthetic oil to function properly. Skipping oil changes can lead to increased friction, overheating, and engine wear. Always follow your manufacturer’s recommended oil change intervals.

2. Ignition System Failures

Faulty spark plugs, ignition coils, or fuel injectors can lead to rough idling, misfires, and sluggish acceleration. If your INFINITI isn’t starting smoothly, your ignition system may need attention.

3. Cooling System Malfunctions

Your INFINITI’s cooling system works to regulate engine temperature. A malfunctioning thermostat, clogged radiator, or leaking water pump can lead to overheating and engine damage.

4. Fuel System Problems

If fuel isn’t reaching the engine efficiently, performance and fuel economy suffer. Clogged fuel injectors, a weak fuel pump, or an obstructed fuel filter can cause issues with acceleration and overall drivability.

5. Failing Sensors and Electronic Components

INFINITI vehicles are equipped with advanced sensors that help regulate engine performance. If a mass airflow (MAF) sensor, throttle position sensor, or oxygen sensor fails, it can throw off the air-fuel mixture and lead to poor performance and efficiency.

Should You Keep Driving with Engine Problems?

Driving with an engine issue can make matters worse. Overheating, misfires, or power loss could lead to more expensive repairs if ignored. Regular maintenance, including oil changes, system flushes, and sensor checks, can help prevent many of these issues before they start.

However, if you’re constantly dealing with recurring repairs and rising maintenance costs, it may be time to upgrade to a newer, more efficient INFINITI.

When to Consider a New INFINITI

If your engine repairs are becoming too frequent or expensive, upgrading to a newer INFINITI may be the smarter choice. Modern INFINITI models offer:

• Turbocharged performance with improved fuel efficiency
• Advanced safety and driver-assist technologies
• A luxury driving experience backed by INFINITI’s reputation
