The most common reasons a 2020 Hyundai Santa Fe 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 2020 Hyundai Santa Fe 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 2020 Hyundai Santa Fe?

To effectively diagnose the tire pressure warning light issue on your 2020 Hyundai Santa Fe, 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 recommended levels outlined in your vehicle'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, which could indicate a more serious problem. If the tire pressure appears correct and the tires are in good condition, consider resetting the tire pressure monitoring system, as temporary fluctuations can sometimes trigger the warning light. Additionally, examine the valve stems for any signs of leaks or damage that might be contributing to pressure loss. If, after these steps, the warning light remains illuminated, it is advisable to consult a mechanic or visit a Hyundai service center for a comprehensive diagnosis. By following this diagnostic approach, you can systematically address the issue and ensure your vehicle's safety on the road.

What could cause the tire pressure warning light to remain on in a 2020 Hyundai Santa Fe?

When the tire pressure warning light remains on in a 2020 Hyundai Santa Fe, it can indicate several common issues that DIYers can troubleshoot. The first step is to check the tire pressure in all four tires, as low pressure is the most frequent cause of the warning light. If the pressure is within the recommended range, the next consideration should be the tire pressure sensors themselves; a faulty sensor may need replacement. Additionally, the sensors might require recalibration to ensure they are functioning correctly, which can sometimes be done with the right tools at home. If these steps do not resolve the issue, it may be necessary to investigate potential electrical faults within the tire pressure monitoring system, which could require a diagnostic check. Lastly, ensure that the sensors are clean and free from any debris or obstructions, as these can interfere with their operation. By methodically addressing these factors, you can effectively troubleshoot and potentially resolve the issue of the tire pressure warning light in your Hyundai Santa Fe.

What should I do if the tire pressure warning light stays on in my 2020 Hyundai Santa Fe?

When the tire pressure warning light remains illuminated in your 2020 Hyundai Santa Fe, it is crucial to act promptly to avoid potential safety hazards and costly repairs. Ignoring this warning can lead to underinflated tires, which not only compromise your vehicle's handling and fuel efficiency but also increase the risk of tire blowouts. Start by checking the tire pressure in all tires, including the spare, using a reliable gauge to ensure they meet the manufacturer's specifications. If you find any tires are underinflated, inflate them to the correct levels immediately. Additionally, inspect your tires for any visible damage, as issues like punctures or bulges can exacerbate the problem. After making necessary adjustments, resetting the tire pressure monitoring system is essential to clear the warning light. If the light persists, it may indicate a malfunction within the monitoring system itself, necessitating a visit to a qualified mechanic. Addressing these issues without delay not only enhances your safety on the road but also helps maintain the longevity of your tires and vehicle.
