I just hit 400 miles today. This is a great vehicle to drive. Very happy with it. I wanted to bring up some things I've noticed and see if they are considered "normal" for this vehicle. It is a new model, so I'm not sure what normal really is.

Transmission: I felt a slight shudder today while driving slow. I believe it was from 2nd to 3rd. I have noticed that if I give it more gas from a dead stop, the shifting is more on point and smoother. This trans likes to shift quickly into second. It's not the smoothest from a dead stop. Giving it more gas from a dead stop definitely helps with this.

Noises: When coming to a stop, I can hear what I believe is the AWD system. It's very faint. I'm not exactly sure what it is or how to describe it. I also heard some clicking noises when at a dead stop.

These may all be normal I figured I'd just throw it out there and see what others have noticed.

I don't know if it's normal or not but I have felt this too, although maybe at different times than yours. When I give it too much gas from a dead stop I feel a delay and then a slight lurch. To avoid that I try to give it less gas from a stop so that it smoothly shifts into 1st. but... when I do that I also feel it shudder (going from brake to light gas). The shudder is very subtle though. I doubt passengers feel it. But I'm curious how to avoid it.

When I put the car in park and turn it off, I also hear noises. One sounds like a long soft beep. Not sure what it's coming from. (It's not a bad sound or loud, just unexpected). They're more noticeable from outside the car, when I open the door immediately after shutting it off.

I get something similar in my 2016 Soul SX, it could be a self-check before it shuts down or something timing out from the various safety systems.

Some sources of 'normal' sounds after turning off your car can include cooling fans, fuel pump, headlights, evaporator venting of fuel tank and cooling of aluminum and metallic parts after shutting down the engine. My CX-5 will sometimes run the cooling fan for a short bit after I turn the car off and leave it in the garage. My 4Runner sometimes has a low whirring noise while parked in the garage and after investigation I found that it was normal fuel vapour venting.

I have about a thousand miles on mine, and today as I was on a highway on ramp accelerating, the rpms shot up close to 5k with seemingly no upcoming shift. I got nervous and backed off the throttle so the car did end up shifting. No I was not in sport mode nor was I heavy on the gas. I'm hoping this is a one off situation...

The throttle position is sensitive in two ways. One is the actual position of the throttle, and the other is how fast you put it there. The computer is measuring the speed of the throttle pedal direction. I didn’t know the throttle is hinged on the bottom like a organ pedal. The standard is to hinge it at the top.

Yeah, this is the first car I've had with a bottom hinged gas pedal. Though you may have noticed the debris piles up rather quickly in that lower hinge depression. :unsure:

So....after about 1400 miles, I'm not so sure how "smooth" the tranny really is. At slower speeds, there almost a rolling resistance to it. Almost a slight lurching if you will. In comparison to my son's 16 Camry, it is downright choppy in nature. Even he as a 17 year old noticed this and likened the shifts to his 02 Accord's tranny. He said he felt like it "shifts hard" and compared to the Camry with 64K on it, it certainly does. Do you guys think this is because of the AWD? I had a 03 Pilot with the VTM-4 system and never felt the same degree of herky jerkeyness that I feel in the CX-30. Thoughts??

It could very well be the AWD. That's a great point. I don't know. I feel like mine has smoothed out now that I have about 900 miles on it. From a dead stop off the line, I have found that if you give it a good amount of gas, it's smoother. Either I'm getting used to it, or the car has learned my driving behavior and adjusted. The shifting once you're moving is very sharp and precise. Sport mode I feel corrects a lot of this, but I don't keep it in sport mode long.

Unfortunately the shifting patterns in so many automatics today are geared towards fuel economy. There are instances when I have to give it a good amount of throttle to get it to downshift.

I also have similar "beep" sound when I turn off the engine, but what is worse I have that same sound oscillating as soon as I turn on the electronics without even starting the engine. It increases in volume during a minute or so then completely goes silent for few seconds and then again increases and again drops - oscillating constantly, regularly, non stop.

As for any other sounds - completely nothing, all seems quiet.
