The most common reasons a 2012 INFINITI M37 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 2012 INFINITI M37 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 on my 2012 INFINITI M37?

To effectively diagnose the tire pressure warning light issue on your 2012 INFINITI M37, begin with the simplest step: checking the tire pressure in all four tires using a reliable tire pressure gauge. This initial check is crucial, as under-inflated or over-inflated tires can trigger the warning light. Ensure that each tire is inflated to the recommended levels specified in your vehicle's manual. Next, conduct a visual inspection of the tires for any signs of damage, such as punctures, cuts, or bulges, which could also be contributing to the warning light. If the tire pressure is correct and the tires appear undamaged, proceed to reset the tire pressure monitoring system following the instructions in your owner's manual. Additionally, inspect the valve stems for any signs of leaks or damage, as these can also cause the warning light to activate. If, after completing these steps, the warning light remains illuminated, it may be time to consult a mechanic or dealership for a more comprehensive diagnosis and repair. By following this methodical approach, you can efficiently address the tire pressure warning light issue and maintain your vehicle's safety and performance.

What could be causing the tire pressure warning light to stay on in a 2012 INFINITI M37?

When the tire pressure warning light remains illuminated in a 2012 INFINITI M37, it can be a source of concern for drivers. One of the most frequent culprits is low tire pressure, which can easily be checked with a tire pressure gauge. Ensuring that all tires are inflated to the manufacturer's recommended levels is a crucial first step. If the pressure is adequate, the issue may lie with a faulty tire pressure sensor, which could require replacement if it fails to provide accurate readings. Additionally, sensor calibration issues can arise, necessitating a recalibration process to ensure proper functionality. Electrical faults within the tire pressure monitoring system can also trigger the warning light, often requiring a diagnostic check to pinpoint the problem. Lastly, external factors such as dirt or obstructions around the sensors can interfere with their operation, so keeping the sensors clean is essential. If these troubleshooting steps do not resolve the issue, consulting a qualified mechanic or dealership is recommended for a thorough inspection and repair.

How urgent is it to address the tire pressure warning light that stays on in a 2012 INFINITI M37?

Addressing the tire pressure warning light in your 2012 INFINITI M37 is not just a matter of convenience; it is a critical safety concern that should be prioritized. When this warning light remains illuminated, it signals that your tires may be underinflated, which can severely compromise your vehicle's handling, braking, and overall stability. Driving on underinflated tires not only increases the risk of a blowout but also leads to decreased fuel efficiency and accelerated tire wear, resulting in costly replacements. Moreover, the warning light could indicate a more serious issue, such as a tire leak or malfunctioning tire pressure monitoring system, which, if ignored, could escalate into a dangerous situation on the road. Therefore, it is essential to regularly check your tire pressure and inflate your tires to the recommended levels as outlined in your owner's manual. By taking these proactive steps, you can ensure your vehicle operates safely and efficiently, ultimately protecting both yourself and your investment.
