While driving in rain and high humidity, going south on route 95, a/c cooling stopped working and only warm air was blowing through the vents. Stopped working for over an hour, until I stopped for gas in ft. Piece. When I restarted, it began to work and worked for another 20 minutes before it stopped. I brought it to the dealer on Jun 3. Dealer said he could not reproduce the problem and would do nothing. It happened again on Jun 13 while driving. I went back to the dealer and he again said he could not reproduce it and would do nothing. I reported it Hyundai would said it could not be reproduced and would do nothing. I found numerous instances, on the internet, of people reporting this problem, but was told unless I could reproduce on my vehicle, nothing would be done. I have to wait for it to happen again and hope the car dealer is open.
