One problem related to timing tensioner has been reported for the 2016 Mazda CX-5. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2016 Mazda CX-5 based on all problems reported for the 2016 CX-5.
During a routine inspection by the dealer following an oil change the mechanic discovered that the drive belt tensioner had begun to leak and if not replaced (at $400) will cause the engine to fail and will strand motorist. Current mileage 53, 824. With little effort I discovered that this is a well-known problem with this vehicle with many failing at around the 30k mile mark. Looks like a design flaw that Mazda USA is passing onto the consumer.
