The most common reasons a 2019 Genesis G80 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 2019 Genesis G80 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 of a TPMS control module failure are failing to alert the driver of underinflation or overinflation of one or more tires, failure to communicate with the body control module or TPMS sensors, or erroneously reporting incorrect tire pressure.

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 2019 Genesis G80?

To effectively diagnose the tire pressure warning light issue in your 2019 Genesis G80, begin with a thorough check of the tire pressure in all four tires using a reliable tire pressure gauge. This initial step is crucial as it ensures that the tire pressure aligns with the recommended levels outlined in your owner's manual. Next, conduct a visual inspection of each tire for any signs of damage, such as punctures, cuts, or bulges, and look for any foreign objects that may be lodged in the tread, as these can lead to air leaks. If the tire pressure is correct and no visible damage is found, consider resetting the tire pressure monitoring system (TPMS), as it may require recalibration. Instructions for this process can typically be found in your owner's manual. However, if the warning light remains illuminated despite these efforts, it is wise to consult a mechanic or an authorized service center for a professional evaluation. By following this diagnostic approach, you can systematically address the issue, starting with the simplest solutions before moving on to more complex diagnostics.

What could be causing the tire pressure warning light to stay on in a 2019 Genesis G80?

When the tire pressure warning light stays on in a 2019 Genesis G80, it can indicate several common issues that DIYers can troubleshoot. Start by checking the tire pressure in all four tires, as low pressure is the most frequent cause of the warning light. If the pressure is within the recommended range, inspect the tire pressure sensors for any faults, as a malfunctioning sensor may need replacement or recalibration. Additionally, consider the possibility of dead sensor batteries, which can lead to inaccurate readings. It's also important to examine the wiring and connections for any damage or looseness, as these can disrupt the tire pressure monitoring system. Keep in mind that environmental factors, such as significant temperature changes, can affect tire pressure, so reassessing the pressure during these fluctuations is advisable. Finally, if the issue persists, recalibrating the tire pressure monitoring system according to the manufacturer's instructions may help resolve the problem. By methodically addressing these potential causes, you can effectively troubleshoot the tire pressure warning light in your Genesis G80.

How urgent is it to address the tire pressure warning light on a 2019 Genesis G80?

When the tire pressure warning light illuminates on your 2019 Genesis G80, it signals an urgent need for attention that should not be overlooked. Ignoring this warning can lead to serious safety risks, as improper tire pressure significantly impacts your vehicle's handling, braking, and overall stability. This can create hazardous driving conditions, especially in adverse weather. Additionally, driving on under-inflated or over-inflated tires accelerates uneven tire wear, which not only shortens the lifespan of your tires but can also lead to costly replacements. Furthermore, maintaining the correct tire pressure is essential for optimal fuel efficiency; neglecting this can result in decreased gas mileage, ultimately increasing your fuel expenses. For those who enjoy DIY maintenance, addressing the tire pressure warning light is a straightforward task that can enhance your vehicle's performance and safety. By regularly checking and adjusting your tire pressure, you ensure a smoother ride and prolong the life of your tires, making it a crucial aspect of vehicle upkeep.
