Why does the new car display a check tire pressure warning?
2 Answers
The new car displaying a check tire pressure warning may be caused by small nails puncturing the tire in blind spots or air leakage in the tires. The specific reasons and solutions are as follows: Small nails puncturing the tire in blind spots: If there are small nails puncturing the tire in blind spots, the car's tire pressure will become unstable, triggering the check tire pressure warning. Solution: Immediately go to a professional repair shop to fix the tire. Air leakage in the tires: This may be caused by incorrect driving habits, parking the car by the roadside, or driving on roads with sharp objects that lead to tire leaks. Solution: Replace with the spare tire and drive to the nearest repair shop for assistance.
I also encountered the tire pressure warning popping up when driving my new car, which was quite annoying. Usually, this is the tire pressure monitoring system indicating that the pressure in one of the tires may be too low or too high. The most common reasons are slow leaks—like a nail puncture without a blowout, a sudden temperature drop causing pressure loss, or a faulty sensor signal. I recommend immediately using a reliable tire pressure gauge to measure all four tires. The standard values are usually listed on the door frame or in the user manual, typically between 2.2-2.5 bar. If the pressure is low, refill it promptly. If all readings are normal, it might be a false alarm—try restarting the car or driving a few kilometers to reset the system. Never ignore it, as incorrect tire pressure can accelerate tire wear, increase fuel consumption, and even lead to loss of control at high speeds. For a new car, sometimes the sensors aren’t properly calibrated during production. It’s quick and easy to visit the dealership for a warranty check and ensure other components are functioning properly—safety first.
