So today I parked my car after a 20 minute drive and noticed a slight hissing or steaming noise from the engine area. When I opened the hood it was coming from the AC components. It was 95 degrees today and I had the AC running. Just wondering if this is normal or something to get checked? My car is still under the 3 year bumper to bumper warranty until the end of the month.

 

some AC noise is normal after running it for awhile. Without hearing it myself in person, I can't say for sure if what you're hearing is the normal noise or something abnormal

 

The A/C system is a pressurized system, and a little bit of equalization would be normal, especially on a hot day. If you're nervous about it, just go visit the dealer and have someone who knows the vehicles listen to it and see what they think.
