The signal for low tire pressure appeared just before I had a road trip planned from San Diego heading north. I checked the pressure and it was way down. So I filled it up and it went down in a few hours. But no one I called in San Diego could do a tire repair for a walk in without taking all day. The next morning I filled it with air again, and made it to Santa Barbara without the signal lighting. I called Santa Barbara Tire and Service Center because they had really good reviews. They said sure, bring it right in. I was out of there 40 minutes later with a nail removed and my tire patched. Definitely a 5-star experience! Many thanks.
