AC and Transmission Problems
 Was good for the first two years, then the AC started blowing hot air, had high pressure line replaced under warranty.  A year later the same thing happened, this time the low pressure AC line, and out of warranty.  The hose and metal crimps seemed to have failed, replacement hose was more supple than original hose.  After 4.5 years and 79,000 miles the transmission has started slipping between 2nd and 3rd gear, with no check engine light on.  Taking it to the dealer for diagnosis in a couple of days.  Purchased mechanical breakdown insurance (MBI) from credit union, which is good for 4 more months, so I hope it will be covered.
