2500 mi Check Engine Soon Light came out twice within one month. PC module was replaced. 
18100 mi Check Engine Light came back on. Dealer replaced the oxygen sensor. Check engine light came back on a few days after the oxygen sensor was replaced on 10/11. Took it back to the dealer on 10/23. Dealer checked for codes. PO137, P2096. Rear oxygen sensor low voltage. Post cat lean. Checked wiring from rear oxygen sensor to PCM. Wiring was good. Monitored fuel trims - good.. Swap engine. No vacuum leaks found. Checked fuel pressure - good. Advised to try different source of fuel. Didn't work. Light has come back on. 
34000 mi Check Engine Light was on again. Dealership technician said the oxygen sensor should be replaced. They still cannot figure out what triggers the check engine light on so very often. Dealership replaced the oxygen sensor one more time, the check engine light came on again just in three days after the replacement. Returned the vehicle to the dealership at the end of the lease. 
The check engine light came on, and I took the car to the dealership. They "reflashed" something and I was on my way.

Ignition system went totally haywire. Got "Keyless system malfunction" error codes (no start), OBD codes relating to ABS and SBCS systems, throttle bottle and starter clicking constantly after the car was turned off. Most concerningly it ended up devolving into a situation where we could not turn off the engine without pulling a fuse. The car would cycle through "off," accessory, and on modes inside (gauges, accessories, etc.), but the engine remained on and running the whole time. I was able to usually return the car to a drivable by disconnecting the battery and waiting long enough for the ECU to reset. The vehicle spent days at the dealer but they were unable to find anything wrong. We ended up trading the vehicle in for another brand. Some research I did indicated it might be related to multiple TSBs related to the ignition system for 2013-early 2014 CX-5s. The car was unsafe...should've been a recall.
