Occasional odor from A/C. There was a service bulletin that called for a coating be applied to the evaporator (I believe). In the process, they said the system started losing pressure, so they discharged and recharged it at no extra cost. TPMS system fault reported after driving 20 minutes or so. Consistently comes on if driven that long. No tire pressure reading when it's on, reads fine when not. They re-learned the tires, which I had tried before. Still a problem. $0 cost.
