The most common reasons a 2021 Chevrolet Silverado 3500 HD 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 2021 Chevrolet Silverado 3500 HD 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 2021 Chevrolet Silverado 3500 HD?

When faced with a persistent tire pressure warning light on your 2021 Chevrolet Silverado 3500 HD, 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 that could lead to air loss. If the tires appear fine, attempt to reset the tire pressure monitoring system following the instructions in your owner's manual, as this can sometimes clear false alerts. Additionally, examine the valve stems for any signs of leaks or damage. If the warning light remains illuminated, using a diagnostic tool to scan for fault codes related to the tire pressure monitoring system can provide insights into any underlying issues. Finally, inspect the tire pressure sensors, which are located inside the tires, for any malfunctions. If these steps do not resolve the issue, consulting your owner's manual for further troubleshooting guidance or seeking assistance from a professional mechanic may be necessary to ensure your vehicle is safe and roadworthy.

What could be causing the tire pressure warning light to remain on in a 2021 Chevrolet Silverado 3500 HD?

When the tire pressure warning light remains illuminated in your 2021 Chevrolet Silverado 3500 HD, it can be frustrating, but understanding the common problems can help you troubleshoot effectively. One of the primary culprits is low tire pressure, which can occur due to natural air loss, punctures, or leaks. Regularly checking your tire pressure with a reliable gauge can help you identify this issue quickly. Another possibility is a faulty tire pressure sensor; if the sensor is malfunctioning, it may not provide accurate readings, leading to the warning light staying on. Additionally, the sensor batteries may need replacement, as they can deplete over time, causing the system to fail in detecting tire pressure accurately. Calibration issues can also arise, where the sensors may need to be reset to ensure they are reading correctly. Lastly, electrical problems within the tire pressure monitoring system or the vehicle's broader electrical system can contribute to the warning light being triggered. If you encounter this issue, start by checking your tire pressure and inspecting the sensors, and if the problem persists, consider consulting a professional mechanic for a thorough diagnosis.

What immediate steps should be taken if the tire pressure warning light remains on in a 2021 Chevrolet Silverado 3500 HD?

When the tire pressure warning light remains illuminated in your 2021 Chevrolet Silverado 3500 HD, it is crucial to act promptly to ensure your safety and prevent potential damage to your vehicle. Ignoring this warning can lead to unsafe driving conditions, such as reduced traction and increased tire wear, which may ultimately result in a blowout or costly repairs. Start by checking the tire pressure in all tires, including the spare, using a reliable gauge to confirm they meet the manufacturer's recommended levels. If you find any tires underinflated, inflate them accordingly to restore optimal performance. Additionally, inspect each tire for visible damage, as any punctures or bulges could compromise their integrity and require immediate attention. Once you have adjusted the tire pressures and checked for damage, reset the tire pressure monitoring system as outlined in your owner's manual to clear the warning light. If the light persists despite these efforts, it is essential to consult a professional mechanic, as there may be deeper issues with the monitoring system that need to be addressed. Taking these steps not only enhances your vehicle's performance but also ensures your safety on the road.
