2011 Hyundai Sonata: Weekend Trip and Odd TPMS
July 26, 2010
On Saturday I decided to check out the 2010 Gilroy Garlic Festival. Ever eaten garlic ice cream? Me neither. It's pretty good, actually (if you like garlic). The ride of choice was our 2011 Hyundai Sonata, which proved to be a pleasant companion. It was roomy, quiet and got about 30 mpg in combined fuel economy.
The one weird issue, however, was the Sonata's tire pressure monitoring system. On my way to Gilroy the TPMS warning light illuminated. "Oh great," I thought to myself. I wasn't too happy with the thought of driving with a space-saver spare tire on for the rest of the trip.
I stopped at a Chevron next to Casa de Fruta, which is a fruit-and-nut store (and popular rest stop) near Hollister, Calif. (pictured above). The Sonata won't tell you what the tire pressures are, so I had to check them manually. I only had one of those cheap-o pencil tire pressure gauges with me, but even with that I could tell that all of the tires were pretty close to the recommended pressures. The left-front was perhaps a couple psi lower than the rest of the tires, but it shouldn't have been enough to trip the warning light.
When I started the Sonata back up, the TPMS light was still on. At that point I figured I'd keep driving to Gilroy and check the pressures again. But about five minutes after leaving Casa de Fruta the TPMS light went out. It hasn't come back on since, and subsequent checks of the tires have revealed no leak or puncture. Like I said, weird.
