The most common reasons a 2009 INFINITI M35 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 2009 INFINITI M35 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.

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 2009 INFINITI M35?

To effectively diagnose the tire pressure warning light issue on your 2009 INFINITI M35, begin with a thorough check of the tire pressure in all four tires using a reliable tire pressure gauge. Ensure that the readings align with the recommended PSI found in your owner's manual or on the sticker located on the driver's side door jamb. Next, inspect each tire for any visible 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, tire bead, and tread area; a simple mixture of soap and water can help reveal leaks, as bubbles will form where air escapes. If everything appears normal, consider resetting the Tire Pressure Monitoring System (TPMS) according to the instructions in your owner's manual, as sometimes the warning light can be triggered by temporary issues. However, if the warning light remains illuminated after these checks, it may be prudent to consult a mechanic or dealership for a professional diagnosis and repair, ensuring your vehicle's safety and performance. By following this systematic approach, you can effectively address the tire pressure warning light issue and maintain your vehicle's optimal condition.

What could be causing the tire pressure warning light to stay on in a 2009 INFINITI M35?

When the tire pressure warning light stays on in a 2009 INFINITI M35, it can signal several underlying issues that DIY enthusiasts can address. 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, as they may be malfunctioning or require a battery replacement. Additionally, consider whether the tire pressure monitoring system needs recalibration, which can help resolve any discrepancies in readings. It's also important to visually inspect the tires for any signs of leaks or damage, as these can lead to fluctuations in tire pressure. If these steps do not resolve the issue, an electrical fault within the system may be the culprit, requiring further diagnosis. By methodically investigating these potential problems, you can troubleshoot the persistent tire pressure warning light and maintain your vehicle's safety and performance.

How urgent is it to address the tire pressure warning light on a 2009 INFINITI M35?

Addressing the tire pressure warning light on your 2009 INFINITI M35 is not just a matter of convenience; it is a critical safety concern that requires immediate attention. Ignoring this warning can lead to severe consequences, including compromised vehicle handling and stability, which are essential for safe driving. Underinflated tires can significantly increase the risk of accidents, particularly in adverse weather conditions where traction is already diminished. Additionally, neglecting to check and maintain proper tire pressure can result in increased fuel consumption and uneven tire wear, leading to costly replacements and repairs down the line. Therefore, it is imperative to act swiftly when the tire pressure warning light illuminates, ensuring both your safety and the longevity of your vehicle's tires.
