The most common reasons a 2018 Jeep Compass 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 Jeep Compass 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 Jeep Compass?

To effectively diagnose the tire pressure warning light issue in your 2018 Jeep Compass, begin with a straightforward approach by checking 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, conduct a visual inspection of the tires for any signs of damage, such as punctures or bulges, which could also trigger the warning. If the tire pressure is correct and the tires appear undamaged, consider resetting the tire pressure monitoring system (TPMS), as sometimes the system may need a refresh to clear false alerts. Refer to your vehicle's manual for specific instructions on how to perform this reset. Additionally, inspect the TPMS sensors located on each tire; faulty sensors can lead to persistent warning lights. If, after these steps, the warning light remains illuminated, it may be time to consult a professional mechanic for a thorough diagnosis and repair, ensuring your vehicle remains safe and roadworthy.

What could cause the tire pressure warning light to stay on in a 2018 Jeep Compass?

When the tire pressure warning light stays on in a 2018 Jeep Compass, it is essential to identify the underlying issues to ensure safe driving. The most common reason for this warning light is low tire pressure, which can result from natural air loss or punctures. Regularly checking and inflating your tires to the recommended levels is crucial for maintaining optimal performance and safety. If the tire pressure is adequate, the problem may stem from a faulty tire pressure sensor that fails to provide accurate readings. In such cases, recalibrating the sensors can often restore their functionality. Additionally, electrical or wiring issues within the tire pressure monitoring system may also trigger the warning light, necessitating a professional inspection. It's also worth noting that extreme temperature changes can temporarily affect tire pressure, so adjusting the pressure accordingly can sometimes resolve the issue. If these troubleshooting steps do not fix the problem, it may indicate a malfunctioning control module, which would require replacement. Addressing these potential issues promptly is vital to ensure the vehicle operates safely and efficiently.

How urgent is it to address the tire pressure warning light that stays on in a 2018 Jeep Compass?

Addressing the tire pressure warning light in your 2018 Jeep Compass is not just a matter of convenience; it is a critical safety concern that requires immediate attention. When this warning light remains illuminated, it indicates that your tires may be under-inflated, which can severely compromise your vehicle's handling and braking capabilities. Low tire pressure can lead to increased fuel consumption and uneven tire wear, ultimately resulting in costly repairs or replacements. Moreover, ignoring this warning can escalate into more serious issues, such as a flat tire or a dangerous blowout, particularly when driving at high speeds. To ensure your safety and the longevity of your vehicle, it is essential to regularly check your tire pressure, inflate your tires to the recommended levels as outlined in your owner's manual, and promptly address any underlying issues with the tires or the tire pressure monitoring system. Taking these steps not only enhances your driving experience but also safeguards you and your passengers on the road.
