I had my oil changed at the dealership on Friday. They did not rotate the tires. On Monday morning, after I started the engine, I noticed the TPMS light is on. According to the owner's manual, it isn't supposed to come on until you go over 20 MPH. I checked the tire pressure, and it's low in all 4 tires. According to the door jam label, the front tires are supposed to be 33 psi, but my left front tire is 23 psi. The other three tires are all approximately 25. You'd think the dealership would check the tire pressure when they did oil change. Odd that all 4 tires would lose pressure 3 days after an oil change.
