Why does my QX56’s check engine light come on when I start it?

Generally, your check engine light turning on upon ignition is not a bad thing. It’s just your QX56 firing up its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.

Why is my Infiniti QX56 making engine noise?

Strange engine sounds can be a sign something’s off in your Infiniti QX56. Knocking or tapping could be a symptom of low oil. Whistling sounds could mean you have an intake leak or misaligned belt. Squealing can be traced back to a loose fan belt, and grinding might be coming from the brakes, not the engine.

What could damage my Infiniti QX56 engine?

Certain driving habits can damage your engine and should be avoided. These habits include 'running on fumes,' revving your engine while the vehicle is in Park, or accelerating too quickly, too soon. Protect your engine’s performance and efficiency by distancing yourself from these habits.

Can I use water in my Infiniti QX56 radiator?

Only in emergencies. A 50/50 mix of coolant and water (or a pre-mixed) coolant is recommended. However, if you must keep driving when you're out of coolant, it's better to drive with water in your coolant reservoir than nothing.

What could cause my QX56 engine to suddenly stop?

There are different reasons your QX56 vehicle engine could suddenly stop. You may be looking at a lack of fuel, faulty sensors, issues with the ignition system, engine overheating, electrical problems, or mechanical troubles.
