The most common reasons a 2015 INFINITI QX50 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 2015 INFINITI QX50 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 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 2015 INFINITI QX50?

To effectively diagnose the tire pressure warning light issue in your 2015 INFINITI QX50, 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 specified in your vehicle's manual, as improper inflation is a common trigger for the warning light. Next, inspect the tires for any visible damage, such as punctures, cuts, or bulges, which could indicate a more serious problem. If the tires appear to be in good condition, consider resetting the tire pressure monitoring system, as temporary glitches can sometimes cause the warning light to activate. Additionally, examine the valve stems for any signs of damage or leaks that might be contributing to the issue. If, after these steps, the warning light remains illuminated or if you are unable to identify the problem, it is wise to consult a mechanic or authorized service center for a professional diagnosis and repair. By following this diagnostic approach, you can systematically address the tire pressure warning light issue and ensure your vehicle's safety on the road.

What could cause the tire pressure warning light to stay on in a 2015 INFINITI QX50?

When the tire pressure warning light remains on in your 2015 INFINITI QX50, it can be a source of concern, but understanding the common problems can help you diagnose the issue. The most frequent culprit is low tire pressure, which can easily be checked with a tire pressure gauge. Ensure all tires are inflated to the manufacturer's recommended levels, as even a slight deficiency can trigger the warning light. If the pressure is adequate, consider the possibility of a faulty tire pressure sensor; these sensors can wear out over time and may need replacement. Additionally, sensor calibration issues can arise, particularly if tires have been rotated or replaced, necessitating a recalibration to ensure accurate readings. Electrical problems, such as damaged wiring or blown fuses, can also cause the warning light to stay illuminated, so a thorough inspection of the vehicle's electrical system may be required. Lastly, if all else checks out, there could be a malfunction within the tire pressure monitoring system itself, which may require professional diagnostic testing. Addressing these issues promptly is crucial for maintaining vehicle safety and performance, so if the light persists after your DIY efforts, consulting a qualified mechanic is advisable.

What immediate actions should be taken if the tire pressure warning light remains on in a 2015 INFINITI QX50?

When the tire pressure warning light remains illuminated in your 2015 INFINITI QX50, it is crucial to act promptly to avoid potential safety hazards and costly repairs. Ignoring this warning can lead to decreased vehicle handling, increased tire wear, and even tire blowouts, which pose serious risks on the road. 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 underinflated, inflate them to the correct level, and if they are overinflated, release some air. Additionally, visually inspect each tire for any signs of damage, such as punctures or bulges, as these can compromise your safety. After making necessary adjustments, reset the tire pressure monitoring system to clear the warning light. If the light persists despite your efforts, it is essential to consult a professional mechanic, as there may be a deeper issue with the monitoring system that requires expert attention. Taking these steps not only enhances your vehicle's performance but also ensures your safety and that of others on the road.
