The AC system may blow warm air due to refrigerant loss caused by a leaking low pressure AC hose. These hoses commonly develop a leak at the hose crimp connection.Google+

Nissan Maxima Low Pressure AC Hose May Leak at Crimped Connection

I'm not sure how old these posts are so I dated mine. I have checked the recall website and there isn't anything there on this AC hose. I have replaced mine twice already and it has gone bad again in the same area, by the crimping, where the rubber meets the metal piping. It would not be so bad if it wasn't for the ridiculous price of $400 dollars to repair (mostly labor) only to return just after the warranty runs out with the same exact problem and the stealership is more than happy to charges full price. Although most recalls are safety driven, this is obviously a defective part. I have reported this to Nissan and I believe that everyone should let Nissan know their story in addition to posting it on websites such as this one. If anyone has had any luck with Nissan, please let me know. Thanks.
My low side ac line also leaked at the crimp and later caused the clutch bearing to fail and the clutch to burn out. I have owned Maxima's most of my life, but now my next vehicle will definitely NOT be a Nissan unless the Auto maker come to a solution to assist all of us.

Low press hose leaking, dealer wants $315.00 for hose alone. Should be a recall after a lil checking. Last Nissan for me.
The A/C wasnt blowing cold air. The low pressure hose was replaced

I am in agreement with all on the A/C low pressure line leak. I owned a 1996 Nissan Maxima that I had for 13 years with 240,000 miles and never had any A/C issues. Purchased this 2006 model used in 2009 with 8900 miles and now having AC issues? Really? I was always a big fan of Nissan. Had lots of success with my first model. Did not think I would have such issues so early on. This seems to truly be an faulty issue that Nissan clearly had to be aware of. Sending my own notes to NIssan Corp.

With only 51,000 miles, my air conditioner went out - dealer said it was the lower AC hose. Took it to my mechanic and he can't find the part anywhere. Apparently I'm not the only one with the problem...

I paid $462.00 the other day to replace 3 lines for air conditioner, freon was leaking.

Low pressure AC leak, $400 to repair. 4 year old car, really?
This should be recall

During a visit to Dealer, their whatever-point inspection they do anytime they service your vehicle, they reported low-side A/C hose leak-right before refrigerant ran out...and right after the warranty ran out. VERY frustrating. I can hear the hiss of the leak if the A/C is turned on. Mighty expensive for the repair, and seeing how many others in the same boat is even more frustrating! I had suspected they found leak because they were looking for it (since system was still working at that time-failed soon after)...now I'm sure of it!

2006 maxima has currently very bad transmission problems (well reported in many blogs), as well as a leak on a/c low pressure hose on crimped fitting. very disappointing quality issues from nissan; after being an enthusiastic fan for many years, this will be the last nissan i'll be buying.
