Hello guys i have been getting different reading from my tire pressure monitor system especially the front driver tire. It reads 31 and the other read 39/39 /37 sometime in the night they ready 37/37/37/33. Could this be a fault or just issues with air pressure? should I have the dealer look into this.

Tire pressure fluctuates due to temperature. Driving also heats up the air inside the tire, which raises the pressure as well. When the temperature outside drops, the tire pressure drops.

There's likely nothing wrong. The manual recommends the cold tire pressure s/b 32 front and 30 rear. Most here prefer 34 front and 32 rear for a less floaty feeling. My tires are 34/32 and can read as high as 37/35 depending on the outside temp and driving conditions.

Have you taken a reading with a tire gauge?

I notice my left side tire pressure increases faster than the right, but once I am on the highway for a good stretch they equal out.
