The most common reasons a 2019 Fiat 124 Spider 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 2019 Fiat 124 Spider 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 on my 2019 Fiat 124 Spider?

To effectively diagnose the tire pressure warning light issue on your 2019 Fiat 124 Spider, 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 levels recommended in your owner's manual, as improper inflation is a common cause of warning lights. Next, inspect the tires for any visible damage, such as punctures, cuts, or bulges, and look for foreign objects that may be lodged in the treads, which could lead to air leaks. If the tire pressure is correct and the tires appear undamaged, consider resetting the tire pressure monitoring system (TPMS) as outlined in your owner's manual, as sometimes the system may require a reset to clear false warnings. If the warning light remains illuminated after these steps, it is advisable to consult a mechanic or an authorized Fiat service center for a comprehensive diagnosis, as they can identify more complex issues that may not be immediately apparent. By following this diagnostic approach, you can systematically address the warning light and ensure your vehicle's safety on the road.

What could cause the tire pressure warning light to remain on in a 2019 Fiat 124 Spider?

When the tire pressure warning light remains on in a 2019 Fiat 124 Spider, it signals potential issues that need to be addressed for safe driving. The most frequent culprit is low tire pressure, which can be easily checked using a tire pressure gauge; ensuring all tires are inflated to the recommended levels is essential for optimal vehicle performance. If tire pressure is adequate, the problem may stem from a faulty tire pressure sensor that might require replacement. Additionally, the tire pressure monitoring system could need recalibration, a task that can often be performed by following the vehicle's manual or consulting a professional. It's also important to consider electrical issues, such as wiring problems or blown fuses, which can cause the warning light to stay illuminated; a thorough inspection of the electrical components is advisable in this case. Lastly, environmental factors like extreme temperature changes or driving over rough terrain can temporarily trigger the warning light, so it's prudent to recheck tire pressure after such conditions. By methodically investigating these common problems, you can effectively troubleshoot and resolve the tire pressure warning light issue in your Fiat 124 Spider.

What immediate steps should be taken to address the tire pressure warning light on a 2019 Fiat 124 Spider?

Addressing the tire pressure warning light on your 2019 Fiat 124 Spider is crucial for both your safety and the longevity of your vehicle. Ignoring this warning can lead to serious consequences, including reduced traction, increased tire wear, and even tire blowouts, which can compromise your control of the vehicle. Start by checking the tire pressure on all four tires with a reliable gauge, ensuring they meet the recommended levels found in your owner's manual or on the driver's side door jamb. If you find any tires are underinflated, promptly inflate them using an air compressor or portable inflator. Additionally, inspect each tire for visible damage such as punctures or bulges, as these issues can exacerbate the risks associated with low tire pressure. Once you've addressed any inflation or damage concerns, it’s important to reset the Tire Pressure Monitoring System (TPMS) to clear the warning light, which can typically be done through your vehicle's infotainment system. By taking these immediate steps, you not only enhance your driving safety but also prevent potential long-term damage to your tires and vehicle.
