The most common reasons a 2018 Mitsubishi Eclipse Cross 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 Mitsubishi Eclipse Cross 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 Mitsubishi Eclipse Cross?

To effectively diagnose the tire pressure warning light issue in your 2018 Mitsubishi Eclipse Cross, begin with a straightforward approach that prioritizes simpler solutions before delving into more complex diagnostics. Start by checking the tire pressure in all four tires using a reliable tire pressure gauge, ensuring they are inflated to the levels recommended in your vehicle's manual. This initial step can often resolve the warning light if the pressure is simply low. Next, inspect the tires for any visible damage, such as punctures or bulges, which could affect their performance and trigger the warning light. If the tires appear to be in good condition, proceed to reset the tire pressure monitoring system, as this can sometimes clear false alerts. Additionally, examine the valve stems for any signs of leaks or damage, as faulty valve stems can lead to inaccurate pressure readings. If, after these steps, the warning light remains illuminated, it may be time to consult a mechanic or dealership for a comprehensive inspection, as they can identify any underlying issues with the tire pressure monitoring system. By following this methodical approach, you can effectively address the tire pressure warning light and maintain the safety and performance of your vehicle.

What could cause the tire pressure warning light to stay on in a 2018 Mitsubishi Eclipse Cross?

When the tire pressure warning light remains on in your 2018 Mitsubishi Eclipse Cross, it can be frustrating, but understanding the common problems can help you diagnose the issue. One of the primary culprits is low tire pressure, which is easily checked with a tire pressure gauge. Ensure all tires are inflated to the manufacturer's recommended levels, as even a slight drop can trigger the warning light. If the pressure is adequate, consider the possibility of a faulty tire pressure sensor; these sensors can wear out over time and may need replacement. Additionally, sensor calibration issues can arise, particularly if tires have been recently changed or rotated, necessitating a recalibration to ensure accurate readings. Electrical problems within the tire pressure monitoring system can also cause the light to stay on, so inspect the wiring and connections for any signs of damage. Lastly, a simple system reset might be all that's needed to clear the warning light; consult your vehicle's manual for specific instructions on how to perform this reset. By systematically addressing these potential issues, you can effectively troubleshoot the tire pressure warning light in your Eclipse Cross.

How urgent is it to address the tire pressure warning light on a 2018 Mitsubishi Eclipse Cross that stays on?

Addressing the tire pressure warning light on your 2018 Mitsubishi Eclipse Cross is not just a matter of convenience; it is a critical safety issue that demands immediate attention. When this light remains illuminated, it signals that one or more tires may be underinflated, which can severely compromise your vehicle's handling and braking capabilities. This poses a significant risk, especially in emergency situations where quick response is essential. Additionally, driving on underinflated tires can lead to uneven wear, drastically shortening their lifespan and increasing the likelihood of a blowout, which can be both dangerous and costly. Furthermore, low tire pressure can negatively impact your fuel efficiency, leading to higher fuel costs over time. Ignoring the warning light may also indicate a malfunction in the Tire Pressure Monitoring System (TPMS), which could require repairs that add to your expenses. Therefore, it is crucial to check your tire pressure and address any issues as soon as the warning light activates, ensuring your safety, preserving your tires, and maintaining your vehicle's efficiency.
