The most common reasons a 2017 Cadillac CTS 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 2017 Cadillac CTS 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.

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 2017 Cadillac CTS?

When diagnosing the tire pressure warning light issue on your 2017 Cadillac CTS, it's essential to adopt a systematic approach that begins with the simplest solutions. Start by checking the tire pressure in all four tires using a reliable tire pressure gauge, ensuring that the readings align with the recommended PSI found in your owner's manual or on the driver's side door jamb. Next, visually inspect each tire for any signs of damage, such as punctures or uneven wear, which could indicate underlying problems like misalignment. If the tire pressure appears correct and the tires are in good condition, consider resetting the tire pressure monitoring system, as this can sometimes resolve false alarms triggered by temporary fluctuations. Should the warning light remain illuminated, it may be necessary to investigate the tire pressure sensors for faults, which typically requires professional assistance. Finally, using a diagnostic tool to scan for error codes can provide further insights into the issue, helping you pinpoint the exact cause of the warning light. By following this structured diagnostic approach, you can effectively address the tire pressure warning light issue and ensure your vehicle's safety and performance.

What could be causing the tire pressure warning light to remain on in a 2017 Cadillac CTS?

When the tire pressure warning light remains on in your 2017 Cadillac CTS, it can be frustrating, but understanding the common problems can help you diagnose the issue effectively. The most frequent culprit is low tire pressure, which can easily be checked with a tire pressure gauge. If you find that the pressure is below the recommended levels, simply inflating the tires can often resolve the warning light. However, if the pressure is adequate, the problem may lie with a faulty tire pressure sensor, which may require replacement. Additionally, sensor calibration issues can arise, necessitating a recalibration to ensure accurate readings. Electrical problems, such as wiring issues or blown fuses, can also trigger the warning light, so a thorough inspection of the vehicle's electrical system is advisable. Lastly, if the tire pressure monitoring system itself is malfunctioning, it may need professional diagnosis and repair. By systematically addressing these potential issues, you can effectively troubleshoot and resolve the tire pressure warning light concern in your Cadillac CTS.

How urgent is it to address the tire pressure warning light that stays on in a 2017 Cadillac CTS?

Addressing the tire pressure warning light that remains illuminated in a 2017 Cadillac CTS is of utmost importance due to the significant safety risks and potential vehicle damage associated with neglecting this issue. When the warning light is on, it indicates that one or more tires may be under-inflated or over-inflated, which can severely compromise the vehicle's handling and braking capabilities, leading to dangerous driving conditions. Additionally, driving on improperly inflated tires can result in uneven tire wear, increasing the likelihood of premature tire failure and the need for costly replacements. Furthermore, incorrect tire pressure can negatively affect fuel efficiency, causing the vehicle to consume more fuel than necessary, which not only impacts your wallet but also contributes to environmental concerns. Therefore, it is crucial to check the tire pressure regularly, make necessary adjustments, and consult a qualified mechanic to diagnose any underlying issues promptly. By taking these steps, you can ensure a safer driving experience and maintain the overall performance of your Cadillac CTS.
