Tire Pressure Monitor System
 

I have bought a used 08 Acura CSX for like a week ago, still got comprehensive extended acura plus warranty till dec 2013.
And I have driven it everyday.

Then a week later I went to Richmond Acura for my rear brake changed and machined my rotor.

After the service, I started my car, it shows the tire pressure low warning icon in the dash, so I thought, it will probably go away once I drive a few KM, I also used my thumb to press the tire, and its pretty hard as it got a lot of air inside the tire.

So over the weekend (Sunday), I drove down to the states to downtown Seattle, the tire pressure warning light came off. Great as expected.

Yesterday, Monday, drove for like 30 minute, no tire pressure warning light

Until this morning, where the light came up again, I used my thumb to press the tire, and it is still hard.

Whats going on? Should I go back to Richmond Acura?

Thanks

Edit: Acura CSX doesn't have the tire pressure meter of each tires, only warning sign, so I am not sure which tire is low on air.

Go to a gas station and check them....

The TPMS on Honda and Acura are not cheap. Get it looked after while still on warranty.

The thumb test?

Dude, buy a tire pressure gauge.

Thumb test :facepalm:

Are you female? Cuz my friend had thought the exact same thing when I had to help her after she got stuck with a flat tire.
