New owner #3 of 2009 with similar cooling problem at 138k private purchase. A/C quit completely within one day of ownership! Serious leak in condenser/evaporators. Cost is $2000 to replace unit behind dash with tedious dismantling 3/4 of repair cost. By law had to evacuate all Freon & bypass system until leak fixed. As prior post noted a simple Freon recharge at best good for about 2 weeks & I suspect this was done to mask problem by owner #2 prior to sale.
