Deceleration/braking downshifting?

Without any engine mod intentions for my CX-5, diagnostics is my prime consideration for any OBDII scan devices. I might consider the Bluetooth adapter/TQ app for a cheaper alternative for my needs.
 
Yes, normal and good behavior. When you apply the brakes it tells the cars computer you are in slowing down mode and it downshifts to save wear on the brake pads.

I'm not a big fan of this, myself. Brake pads (and for that matter all braking components) are cheaper to replace when they wear out both in terms of parts and labor than engine or transmission repair. On the other hand it does improve the driving experience in common situations, especially in traffic. I can only hope that Mazda has done their homework on this and there will be very minimal loss in lifespan on the engine or transmission.

I am a big fan of this myself (the way the Skyactiv downshifts when slowing down) and confident that Mazda did the durability and reliability testing to go with it. My Lexus 6 speed tranny behaves in similar manner with no negative impact on long-term durability (these IS models have been out since model year 2006), therefore both brake pad life and tranny longevity has been proven to be excellent on gen2 IS series.
 
I always use engine braking with a manual box, never had to change a gearbox, engine, or change discs.
And i'm still on the same pads at 25K, four years.
It does no harm provided its done sensibly.
 
Hello all. I appologize for my lack of knowledge, don't know tat much about cars. I just picked up a beautiful 2014 GS AWD CX 5 on Saturday with 25 km on it. Wife drove it from the dealership back home (180 km highway) while I was in the other car. One thing i did notice was that it was very hard for me to stay with her. She is a very "speed limit" type of driver while I go always +5-10km/hour over the speed limit.
I drove the car in 3 separate ocasions in the weekend and now we have 224 km on it. One thing I did notice was when i would coast towards a traffic light (by trying to get best l/100km) as soon as I would lift my foot off the gas, the car would downshift (normal behaviour) but it would somehow do it "jerky". Now I don't remember that happening during our test drives but the demonstrators have had way more km on them and have been probably more abused. Would this "jerking" go away once the engine is being broken in or is there somehting that I am not doing right?
 
Does this help?

Thank you xtrailman. I did read the thread and my jolts were happening at way lower speeds, when it would downshift fom 3rd to 2nd, from 2nd to 1st etc. I will keep driving it and see if it repeates. My wife drove the car for 180M on the highway and she only had praises. I really hope this does not repeat, maybe it has to do with the fact that I am very gentle on the pedals while my wife is more lead footed. I appologize if I am not observing some of the forum rules, I never had 6 posts in one forum, let alone in one day.
