The most common reasons a 2018 Alfa Romeo Stelvio 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 2018 Alfa Romeo Stelvio 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 are the initial steps to diagnose a persistent tire pressure warning light on a 2018 Alfa Romeo Stelvio?

To effectively diagnose a persistent tire pressure warning light on your 2018 Alfa Romeo Stelvio, start by checking the tire pressure in all four tires, ensuring they are inflated to the manufacturer's recommended levels, as low pressure is a frequent culprit. Next, inspect each tire for visible damage, such as punctures or bulges, which could lead to air loss. If the tires appear to be in good condition, attempt to reset the tire pressure monitoring system by following the instructions in your vehicle's manual, as this can sometimes clear false alerts. Additionally, examine the tire pressure monitoring sensors for any signs of malfunction or damage. If the warning light remains illuminated after these steps, it may be time to seek assistance from a professional mechanic or dealership for a more thorough diagnosis. By following this methodical approach, you can efficiently troubleshoot the issue and potentially resolve it without needing professional intervention.

What could cause the tire pressure warning light to stay on in a 2018 Alfa Romeo Stelvio?

When the tire pressure warning light stays on in a 2018 Alfa Romeo Stelvio, it is essential to identify the root cause to ensure safe driving conditions. The most common issue is low tire pressure, which can result from a puncture, slow leak, or the natural loss of air over time. If the tires are adequately inflated, the problem may lie with a faulty tire pressure sensor that fails to provide accurate readings. In some instances, the sensors may need recalibration to function correctly. Additionally, electrical issues such as damaged wiring or poor connections within the tire pressure monitoring system can also trigger the warning light. Lastly, a malfunctioning control module that oversees the tire pressure system may lead to incorrect readings and a persistent warning light. To maintain vehicle safety and performance, it is crucial to address these issues promptly, and seeking assistance from a professional mechanic for a comprehensive diagnosis is highly recommended.

How urgent is it to address the tire pressure warning light that stays on in a 2018 Alfa Romeo Stelvio?

Addressing the tire pressure warning light in your 2018 Alfa Romeo Stelvio is not just a matter of convenience; it is a critical safety concern that requires immediate attention. When this warning light remains illuminated, it signals that your tires may be underinflated, which can severely compromise your vehicle's handling and braking capabilities. This lack of proper tire pressure can lead to dangerous driving conditions, especially during sudden maneuvers or adverse weather. Furthermore, neglecting this warning can result in uneven tire wear, significantly shortening the lifespan of your tires and increasing the risk of a blowout while on the road. Additionally, underinflated tires can negatively impact your fuel efficiency, leading to higher fuel costs over time. To ensure your safety and maintain optimal vehicle performance, it is essential to check your tire pressure regularly, inflate your tires to the recommended levels, and address any underlying issues with the tires or the monitoring system. Taking these steps promptly will not only enhance your driving experience but also protect your investment in your vehicle.
