The most common reasons a 2018 Chevrolet Silverado 2500 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 2018 Chevrolet Silverado 2500 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 steps should I take to diagnose the tire pressure warning light issue in my 2018 Chevrolet Silverado 2500 HD?

To effectively diagnose the tire pressure warning light issue in your 2018 Chevrolet Silverado 2500 HD, 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, conduct a visual inspection of each tire for any signs of damage, such as punctures, cuts, or bulges, which could indicate a leak or other issues affecting tire pressure. Additionally, look for any foreign objects, like nails or screws, that may be embedded in the tire tread, as these can lead to slow leaks. If the tire pressure is correct and no visible damage is found, proceed to reset the tire pressure monitoring system (TPMS) following the instructions provided in your owner's manual. Should the warning light remain illuminated after these steps, it may be necessary to consult a mechanic or dealership for a more in-depth diagnosis, which could involve sensor replacement or other technical assessments. By systematically addressing these areas, you can effectively troubleshoot the tire pressure warning light issue and ensure your vehicle's safety and performance.

What could cause the tire pressure warning light to stay on in a 2018 Chevrolet Silverado 2500 HD?

When the tire pressure warning light remains illuminated in a 2018 Chevrolet Silverado 2500 HD, it can indicate several underlying issues that DIY enthusiasts should be aware of. The most frequent culprit is low tire pressure, which can result from a slow leak, temperature fluctuations, or improper inflation. It's crucial to check each tire's pressure using a reliable gauge to ensure they are inflated to the manufacturer's recommended levels. If the tire pressure is adequate, the problem may lie with a faulty tire pressure sensor, which could be malfunctioning and failing to provide accurate readings. In some cases, the sensor's battery may need replacement, as these components have a limited lifespan. Additionally, recalibrating the sensors can resolve discrepancies in readings, especially after tire rotations or replacements. Lastly, electrical issues within the tire pressure monitoring system or the vehicle's broader electrical framework could also be at play, necessitating a more in-depth inspection. Addressing these issues promptly is vital for maintaining vehicle safety and performance, so if DIY troubleshooting does not resolve the warning light, consulting a professional mechanic is advisable.

What immediate steps should be taken if the tire pressure warning light remains on in a 2018 Chevrolet Silverado 2500 HD?

When the tire pressure warning light remains illuminated in your 2018 Chevrolet Silverado 2500 HD, it is crucial to act promptly to avoid potential safety hazards and costly repairs. Ignoring this warning can lead to decreased vehicle performance, increased tire wear, and even blowouts, which pose serious risks on the road. Start by checking the tire pressure in all four tires with a reliable gauge, ensuring they meet the manufacturer's recommended levels. If you find any tires underinflated, inflate them accordingly to restore optimal pressure. Additionally, inspect each tire for visible damage, such as punctures or cuts, as these can compromise safety and necessitate repairs or replacements. Once you have addressed any pressure discrepancies or damage, reset the tire pressure monitoring system as outlined in your vehicle's manual to clear the warning light. If the light persists despite these efforts, it is essential to consult a certified mechanic to diagnose any underlying issues with the monitoring system. Taking these immediate steps not only enhances your vehicle's safety and performance but also helps prevent further complications down the line.
