I’m posting based on what seems to be a growing issue as more people enter the summer months to find out their brand new Odysseys start blowing hot air when A/C is turned on. No - you’re not going crazy. Sometimes it works (when you are continuously driving) and sometimes it doesn’t (when waiting at a stoplight or for 10-15 min after being parked in the hot sun). I live in Tucson, AZ and am on my third Honda Odyssey. I’ve never experienced this A/C issue until the 2019 model. I was grateful to have found this forum to prove to the service manager at my dealership that this was indeed a real problem. My service was today and like many previous posts, the repair included an evac and recharge. My particular system was overcharged. I hope Honda and its dealerships get out in front of this problem because a lot of owners of new vans are getting the runaround over what seems to be a widespread issue.
