2017 CX-5 GT
So almost exactly a year ago I bought my 2017GT. 3 months later, my brother was one of the first people to pick up a 2018. Essentially they are identical vehicles...at least from a visual point. Driving the 2 cars is a night and day experience.

Mine seems utterly lazy and sluggish. None of that "zoom zoom" marketing mumbo-jumbo in my car. My brother's 2018 however is everything Mazda claims to be. Snappy, shifts immediately when you provide input on the accelerator, doesn't immediately shift up. Mine it seems, always stays in the highest possible gear and it takes some persuasion to get her to shift down. In general she just seems slugging whereas my brother's car is much more responsive and seemingly always in the correct gear. For what it's worth, I should mention that I had the dealer reset my ECU already.

Anyone else experience this? Could this be a bad ECU unit? Lemon? Also frequent infotainment reboots and a rear side driver door which is mounted crooked (dealer even acknowledged and is setting me up with a body shop to have a look at this.

So what do you guys advise? Have them scan the vehicle....look for something in the ECU? Kinda confused about this.

Thanks in advance!

We have a 2018 and it drives like your brothers. Better than I ever expected for as heavy car with 4 cylinders.

Maybe there is a software update that can improve the driving dynamics of your 2017? I'd ask the dealer.

Thanks! My thoughts exactly. I'll drive by the dealer and ask them. If my car drove like the 2018, I wouldn't be waiting for the turbo :(
 
In addition to the comments above I would add that the transmission is programed for best fuel mileage and therefor the shifts occur sooner. If you want it to drive sporting? then the transmission needs to relearn? Try driving it briskly most of the time and I bet it gets like the 2018. Ed
 
Didn't I read somewhere there is a reset a driver can do? Something about disconnecting the battery for a while which causes the system to forget previous driving habits? Anyone recall that discussion?
 
Disconnecting the battery and push the brake pedal several time to discharge any residual current. This is the usual method to reset the engine control module to the factory default parameters. Make a copy of your radio stations because they will be lost during the procedure. Post back on what you find after the reset and several spirited drives. Ed
 
Autogefuhl did say the cylinder deactivation version seemed a bit more enthusiastic/spritely than the 2017 version
 
I think as I stated that to reset the EMC AND TCM to the factory default you need to do the battery disconnect option. The throttle position reset is to correct a shift-shock issue. Ed
 
One needs to drive aggressive on the throttle for the computer modules to relearn.

I could swear I recall reading that there was some throttle mapping updates and changes between the 2017 and 2018.

I went to Mazda and they reset the ECU for me...not sure how they did that. They did it under warranty too. But I don't see any change.

IF that's the case then it's a bummer because the difference is big. If my car drove like the 2018, I wouldn't be anticipating the release of the Turbo.

2.5 NA with 140KW/252NM on a vehicle that weighs 1751kg can only do so much.

Actually its a general relearn process. The TSB addresses shift shock but it also works to adjust the shift points if you want to for some other reason. I did it early in ownership because I was originally driving it like my old car and the shifts it learned were not optimal.

I'm not sure if the battery disconnect will do anything, but this process will.
 
Does your brother keep his in SPORT mode? Have you tried putting yours in SPORT mode while driving? While not the most fuel efficient, it is more fun and peppier to drive.

Be honest OP, are you a granny driver? The CX-5 picks up on habits.

well......yeeeahhh...lol. And I come from a G35 Couple. What has happened to me.. :(

Question asked, question answered. You drive your CX-5 like an old grandma and it's going to learn and respond in kind. Reset the ECU all you want, you don't change how you drive, how's it going to learn any different?
