I got the warning light yesterday, coincidentally when our AM temps were about 25 degrees. It only showed the left front being low, but the PSI was only one pound less than the others, and after driving, they all came up to the same level. The warning never stopped flashing for the left front so I put some air in. The monitor registered the pressure increase but the warning still won't go off. All tires have the same pressure, but it is flashing that the front left is low. This is really annoying and not something I would have expected on a car less than 5 months old.
