Ugh... I shouldn't have wrote what I did. Yesterday driving on the highway to the beach, I run into a traffic jam. As I slow down to a stop, I feel the trans downshift strangely. Then, as traffic starts to move at a faster pace, my trans wouldn't shift up into the next gear (would've been 3rd, I believe). I try manual mode, and it only says "M" without numbers. So, I pull over, turn off and restart car, and it cleared itself up. Manual mode worked fine, also. Strange glitch that I feel is computer related, but with now only 14,500 miles it isn't giving me any more confidence in Mazda trans.
I started reading this thread after I posted my own. I have Rota grids on my CX5 and my wife had a similar issue. Her car jolted, lost power and was in limp mode but no dash lights came on. Took it to Mazda and they said it was the wheels. The diameter is different. I did my research and the wheels are .2inches smaller than the oem 19's. They also have almost the exact revolutions per mile as oem. They reset the car and gave it back and as we pulled out of the service garage, it did the same thing. jolted, a couple of clunks and back to limp mode. Flipped a u'y and brought it back in. This was last week. Today, they were able to put oem wheels on and the problem persisted. There are no fault codes or warning lights coming up. They are now asking Mazda if they are going to replace the tranny or send out a specialist. So frustrating.
Oh, its a 2015 CX5 AWD GT.

After a week of them trying to figure it out, they decided to replace the transmission under the warranty. Good news! Just gotta wait for it to come in now....and hope they didn't F up the wheels!
Mine is a 2016 Touring with approximately 700 miles.
That's great! Did you take any photos of your new car?

The thing is still under warranty, so this is the dealer's problem tomorrow, but I thought I would at least add one more voice to the crowd.
We just had this happen on my wife's 1-year-old 2015 CX-5. Transmission stopped shifting within a mile from home. Engine light, TPS light, TCS light, AT light all came on. The car hadn't been driven for at least six hours previously, ambient temperature was in the 50s.
She pulled over and I had her cycle the system, but she didn't fully turn it off, just stopped and restarted the motor. The problem recurred within a few blocks. She pulled over and turned the car off while we did a little poking around on the net. When she turned it back on the problem did not immediately recur. We drove it the couple of miles home, this time in manual rather than auto mode (because that's what I like and I was driving this time , again without trouble.
At home I pulled out the OBD-II reader and got two codes, each repeated twice:
P0847 - Trans fluid press sensor / switch B circuit low
P0780 - Shift malfunction
I haven't been through this thread entirely, but since this problem was occurring with 2013 models and ours is a 2015 I think it's fair to say that it's not an early production problem, as some suggested, or a problem limited to a certain production run. Also, it seems unlikely that the 2015 does not have software updates that were available in 2013.
I don't recall the mileage on the car, and I'm too lazy to check at the moment, but it's 1 year old now and is unlikely to be more than 15,000.

WHERE IS MAZDA ON THIS ISSUE???
This just happened to me tonight.
I have 2014 CX-5 Grand Touring FWD with about 26k miles. All services have been handled by a Mazda Dealer.
Tonight, while returning from Antioch CA to San Jose CA via I-680 I had a very scary situation that came out of the blue in the hills region.
It had been raining heavily and traffic was fairly heavy. For most of the time I had Speed Control engaged at 60 mph but based on the surrounding traffic I would disengage Speed Control and use the accelerator to slow down or speed up. I had noticed that on occasion there had been a feeling of momentary loss of traction. This happened mainly when changing lanes or transiting a deeper puddle.
I had been driving for about 5 minute using the accelerator to control speed and as I was at just about 60mph (the setting on the Speed Control) I started to change lanes and at about the same time engaged the Speed Control.
THIS IS WHERE THE SCARY PART STARTS.
The car immediately decelerated and at the same time the Tach reading went up to about 6k. I tried to recover using the accelerator but this only made the situation worse because the sped would increase and then decrease. I turned on my Emergency Flashers and managed to make my way over to the curb lane without crashing in spite of the fact that most of the traffic was at about 50~60mph. Once I got to the curb lane I stopped. Then I slowly accelerated up to about 40mph in the curb lane and merged into the right-hand lane once I was confident that I had regained speed control. From this point I did not re-engage Speed Control and was able to drive at about 60mph so I could return home.
I have NEVER had this happen before. It was raining heavily and there was water on the road but I didn't see any spots where it was running across the road like a river.
Let me say, THIS IS NOT ACCEPTABLE and I hesitate to think what might have happened if I had been an inexperienced driver in this situation.
I hope I am not alone in experiencing this and Mazda had developed a software fix for the problem.
I firmly believe this was caused by a conflict between the Traction Control, Speed Control, and feed back coming from a wet surface.

Tom95134 doesn't have Mazda Radar Cruise control (MRCC) like you do so his situation is totally different from yours. And I could not find any warnings of changing lanes from owner's manual while using MECC other than generic "do not rely completely on the MRCC system...", so what is the fault doing lane changes with MRCC on?This is normal. People scoffed at me earlier. You were CHANGING lanes? That was the root cause.WHERE IS MAZDA ON THIS ISSUE???
