A couple of weeks ago we had an alternator failure at 155000 miles on our 2009 CX-9. Unfortunately this was at night on a trip so had it towed to a AAA shop for repair instead of working on it myself. Symptoms, crazy warning lights on the instruments so my wife pulled off the highway and shutdown.. Belts looked OK and key on voltage was down to 10.4 VDC.
Shop replaced alternator with a Mazda unit and new battery. Wondering if it could have been fixed just by a new voltage regulator or brushes? Anyway MTBF for me was 12 years and 155K miles. Your results may vary.
