The most common reasons a 2017 INFINITI QX70 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 2017 INFINITI QX70 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 2017 INFINITI QX70?

To effectively diagnose the tire pressure warning light issue in your 2017 INFINITI QX70, begin with a systematic approach that prioritizes simpler solutions before moving on to more complex diagnostics. Start by checking the tire pressure in all four tires using a reliable tire pressure gauge, ensuring that the readings align with the recommended PSI found in your owner's manual or on the driver's side door jamb. Next, conduct a thorough visual inspection of each tire for any signs of damage, such as punctures, cuts, or bulges, which could indicate a loss of pressure. Additionally, look for potential leaks by examining the valve stems and the tire bead, and consider using a soap and water solution to detect any escaping air, as bubbles will form at the leak sites. If the tire pressure appears normal and no damage is found, attempt to reset the Tire Pressure Monitoring System (TPMS) following the instructions in your owner's manual, as this can sometimes resolve false warnings triggered by temporary fluctuations. However, if the warning light remains illuminated despite these efforts, it may be prudent to consult a professional mechanic or dealership for a comprehensive diagnosis and repair, ensuring your vehicle's safety and performance.

What could be causing the tire pressure warning light to remain on in a 2017 INFINITI QX70?

When the tire pressure warning light stays on in a 2017 INFINITI QX70, it can signal several common issues that DIY enthusiasts should consider. The most prevalent cause is low tire pressure, which can be easily checked and corrected by inflating the tires to the recommended levels. If the tire pressure is adequate, the next step is to investigate the tire pressure sensor, as a malfunctioning sensor may need replacement. Additionally, the sensors might require recalibration to ensure accurate readings, a task that can often be accomplished at home with the right tools and guidance. Electrical faults within the tire pressure monitoring system can also lead to the warning light remaining illuminated, which may require more advanced diagnostic skills. Lastly, a system reset can sometimes clear the warning light, and this process is typically outlined in the vehicle's manual. Addressing these potential issues promptly is essential for ensuring the safety and performance of your vehicle, and if DIY efforts do not resolve the warning light, seeking assistance from a qualified mechanic is recommended.

How urgent is it to address the tire pressure warning light on my 2017 INFINITI QX70?

Addressing the tire pressure warning light on your 2017 INFINITI QX70 is not just a matter of convenience; it is a critical safety concern that should be prioritized. Ignoring this warning can lead to serious consequences, including compromised vehicle handling and increased risk of accidents. Low tire pressure can significantly affect your car's stability, making it harder to control, especially in emergency situations. Additionally, neglecting to check and maintain proper tire pressure can result in uneven tire wear, which not only shortens the lifespan of your tires but also leads to costly replacements. Furthermore, underinflated tires can decrease your vehicle's fuel efficiency, causing you to spend more at the gas station over time. For DIY enthusiasts, regularly checking your tire pressure and addressing any warning lights promptly can enhance your driving experience and ensure your vehicle operates at its best. Taking these steps not only safeguards your safety but also contributes to the longevity of your tires and overall vehicle performance.
