This guy greeted me as I fired up our 2011 Honda Odyssey Monday morning. Did I mention it was 5am and a crisp 48 degrees (hey, that's cold for us)? Anyhow, it wasn't fun.
A check of the tires showed Odyssey's right-front down 5psi as compared to the others. This is typically evidence of a leak. Fifty cents at the gas station compressor bought me 15psi, which gave me 10psi over spec were the issue significant.
I drove 40 miles to the office and rechecked the pressures. No air lost. So I dropped the tire back down another 5psi, keeping it 5psi over the recommendation for the sake of monitoring. This morning the right-front was 5psi over-filled, right where I left it. I dropped it back down to the correct amount and we'll continue to watch it.

You know in California its illegal for them to not let you get air for your tires for free? Most gas stations have a control inside that you just ask them to hit and the air pump will turn on. So next time just go inside and ask and you will save 50 cents! :)

Those compressors at gas stations are full of moisture. You are better off buying an electric one and putting in your garage or a small one that can plug into the power outlet in your car and can keep in the trunk.

Exact same thing happened to me on my Acura TL. Now, granted I was out of town for 3 weeks and the car was just sitting there, when I came back the left rear tire was down 5psi and I had the low tire pressure warning pop up. At least the TL tells you which tire is low on air...

48 degrees in the morning? And I was thinking this was a *hot* January seeing 48 degrees as a high! Where did all my snow go??

it's not unusual on analloy wheel to see a pressure drop after an unusually large negative swing in temps. Here in the upper Midwest I experience it a couple times a year.

Not as fun as a slow leak at -30 when everything is crusted in ice/snow/salt. And you have to remove your gloves to handle the tiny valve caps. COLD metal valve caps.
