I have a 2017 standard model Prius. I really like it, just bought it a few weeks ago, but I am having a lot of breathing issues when driving, and its quite frustrating after spending a good amount of money purchasing. I am having symptoms of sore/burning throat, stomach becoming upset, lungs feeling irritated, and even I believe my eyes might be burning. To try and resolve, I flushed the AC condensation line with a "AC Refresher kit" with little benefit, I replaced the cabin air filter with a top of the line filter having charcoal, ect. Any ideas what could be causing this issue, could a leaky hybrid battery cause fumes in the vehicle? Though it seems to happen when driving only, dont notice it in the AM after car is sitting. Let me know if you have any ideas, thanks! Im going to bring it into a great mechanic, but in 2 weeks...... Not able to at the moment.
I had similar issues a few years ago in my 2004 Prius. Whenever I went on a long trip, I developed hives. The problem turned out to be mice in the HVAC air duct. It took a major cleaning of the AC system to clear up the problem, not just an AC Refresher Kit. JeffD
