The AC compressor may fail causing the AC system to blow warm air, smoke may also appear from the engine. A failed AC compressor will require replacement. Mazda has extended the warranty on these compressors to 5 year or 60K mikes. If these conditions are noted our technicians recommend to turn the AC system off and have it inspected as soon as possible.

Same thing happened in 2010. Now it's happened again in 2015 and Mazda is not covering it. Warranty lasts 12k or 12 months. Just prepare to buy a compressor every 4-5 years or sell it. PCM recall in 2014 after changing out in 2011. And now EGR needs replacing only months after. I'm done with Mazda vehicles.

Keep loosing refrigerant even with sealers. Mazda wanted 1200$CA. Not done repairs so far.
Driving on the freeway when smoke started coming out from under the hood. Now, whenever i turn on the air, the whole car shakes.

AC stopped working, we could hear a hissing noise from under the hood; the car runs fine otherwise. We have not gotten it fixed yet.

it began to start blowing warm air slowly. In the next day it went to not blowing any cold air no matter how high i set the fan.
600 to fix!!
AC compressor had to be replaced...thermostat replaced...check engine light came on, rpm started going crazy from 1000 to 3000 rpm while accelerating, car was losing power, thankfully able to turn into a repair shop. believe it's the turbocharger.
