The most common reasons a 2016 INFINITI Q70L tire pressure warning light stays on are a leaking tire, a wheel that no longer holds air, or a faulty tire pressure monitoring system.
  • Tire Leaking Air: A puncture, valve stem issue, or rim damage can cause a tire to leak air, leading to loss of pressure.
  • Wheel Leaking Air: A puncture or damage to the tire or rim can cause air to leak, resulting in a loss of tire pressure.
  • Tire Pressure Monitoring System: A malfunctioning tire pressure monitoring system can be caused by faulty sensors or a dead battery in the sensor units.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2016 INFINITI Q70L tire pressure warning light stays on?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

When a tire pressure monitoring sensor fails, the tire pressure monitoring system control module will recognize a loss in communication and turn on the warning lamp which indicates the failure. This is most often the case. However, the tire pressure monitoring sensor may also fail by reporting incorrect tire pressures. This could cause a flat tire to go unrecognized, or a properly inflated tire to signal a low or high tire pressure warning.

When a relearn is needed, for any reason, the TPMS warning light will illuminate, and many vehicles will display a message relating to the TPMS system being inoperative or loosing communication. It is important to keep a watchful eye on tire pressures when this system is having issues because there is no warning available for underinflation or overinflation of the tires.

Wheels offer very few symptoms, but these symptoms should never be ignored. Visible cracks on the wheels may appear, especially after hitting a large bump, Most often, this will also be accompanied by loss of air from the tire on that wheel. Also, vibration in the steering wheel is very common when the tire is out of balance, and improper wheel nuts or bolts can cause creaking and popping noises to develop. Again, there are very few symptoms, but they should not be ignored.

The only symptoms of a TPMS control module failure are failing to alert the driver of underinflation or overinflation of one or more tires, failure to communicate with the body control module or TPMS sensors, or erroneously reporting incorrect tire pressure.

The only symptoms requiring diagnosis for the tire pressure monitoring system warning lamp is if the warning lamp has illuminated while the tires have correct air pressure, or if the air pressure for the tires is out of specification and the warning lamp is off. This is because the overwhelming majority of cases where the TPMS lamp illuminates is due to the change in ambient temperature.

What steps should I take to diagnose the tire pressure warning light issue in my 2016 INFINITI Q70L?

To effectively diagnose the tire pressure warning light issue in your 2016 INFINITI Q70L, begin with a thorough check of the tire pressure in all four tires using a reliable tire pressure gauge. Ensure that each tire is inflated to the recommended levels outlined in your vehicle's manual, as improper inflation is a common cause of warning lights. Next, inspect the tires for any visible damage, such as punctures or bulges, which could indicate a loss of pressure. Additionally, look for potential leaks by examining the valve stems and tire beads; a simple mixture of soap and water can help reveal leaks through bubbling. If everything appears normal, consider resetting the tire pressure monitoring system, as sometimes the warning light can be triggered by temporary issues. However, if the light remains illuminated after these steps, it may be time to consult a mechanic or an authorized INFINITI service center for a more in-depth diagnosis and repair. By following this diagnostic approach, you can systematically address the issue and ensure your vehicle's safety on the road.

What could cause the tire pressure warning light to stay on in a 2016 INFINITI Q70L?

When the tire pressure warning light stays on in a 2016 INFINITI Q70L, it can indicate several underlying issues that DIY enthusiasts can troubleshoot. Start by checking the tire pressure in all four tires, as low pressure is the most common reason for the warning light to illuminate. If the pressure is within the recommended range, inspect the tire pressure sensors for any signs of damage or malfunction, as a faulty sensor can lead to incorrect readings. Additionally, consider recalibrating the sensors, which can often be done through the vehicle's onboard settings, to ensure they are accurately detecting tire pressure levels. If the warning light persists, examine the electrical connections and wiring linked to the tire pressure monitoring system for any visible damage or loose connections that could be causing the issue. Lastly, if these steps do not resolve the problem, the control module that manages the tire pressure system may need professional evaluation, as a malfunction here can also trigger the warning light. By methodically addressing these potential issues, you can effectively diagnose and resolve the cause of the tire pressure warning light in your INFINITI Q70L.

What immediate actions should be taken if the tire pressure warning light remains on in a 2016 INFINITI Q70L?

When the tire pressure warning light remains illuminated in your 2016 INFINITI Q70L, it is crucial to act promptly to ensure your safety and the longevity of your vehicle. Ignoring this warning can lead to dangerous driving conditions, including reduced traction and increased risk of tire blowouts, which can result in serious accidents. Start by checking the tire pressure in all four tires with a reliable gauge, ensuring they meet the manufacturer's specifications. If you find any tires are underinflated, inflate them immediately to the correct levels using an air compressor. Additionally, inspect each tire for visible damage such as punctures or bulges, as these can compromise your safety and require urgent repair or replacement. Once you have addressed any pressure discrepancies or damage, reset the tire pressure monitoring system according to your owner's manual. If the warning light persists despite these efforts, it is essential to consult a professional mechanic, as there may be a deeper issue with the monitoring system that needs expert attention. Taking these steps not only enhances your driving safety but also helps prevent costly repairs down the line.
