Curious if anyone else has experienced either of these?
  • Within a day or two after getting my CX-30 I noticed a clicking from the vents when fan was on for AC/heat. Sometimes one vent, sometimes a few at once, as if there were switches clicking on and off under the dash. As far as I can tell this is coming from the front vents only, not the ones in the back seat.
  • After about two weeks (I've had it for about 3 now) on the first start of the day the engine makes a sound that no new car should make - loud, almost rattling, before settling down after about a minute or when I shift into drive. Even after this, it's noticeably louder than it was over the first two weeks.
I really like the CX-30, but these have me wondering if I got a lemon.

I started ours the other day and heard a 15 seconds or so buzzing(?) sound coming from under the hood, then it went away. I haven't noticed it since and kind of forgot about it...

Yes, I hear the faint clicking sounds if I am not playing any music.
Will have to take it to the dealer when things get back to normal.

This may be something different cuz it happens for you when starting the car but definitely the stupid electronic brake is making a whining sound when you turn off the engine. Why do we need to innovate things that do not need innovating ? Like the electronic brake v.s the mechanical handbrake...

Advantages of Electric Parking Brake:
The response time of this system is very short.
The operation is highly reliable.
Improves control of the vehicle while starting from standstill condition on a slope
Electronic handbrakes are more reliable than a mechanical system, free up space for storage in the center console and remove some of the complications from the driving process.

"making a whining sound when you turn off the engine"
When the driver operates the switch, it sends a command to Electronic Brake Module which senses that parking brakes are required to be operated. this module commands the actuators or electric motors installed in the brake calipers to operate. That is the whining sound you are hearing

Ok, we all have our opinions. I think we lived fine with the handrake the way it was. I certainly did not encounter one single issue with it in 30 years of driving.

By the way on this car, a discharged batterry will result in an electronic brake system malfunction dtc. You cannot disengage the brake until you get a boost. This happened to me in my garage. I am sure is as designed.

With more software ecus controlling things in the car, the more complex things become.

I am of the opinion that some things do not need innovation or change, but perhaps refinement, simplification and reliability.

I actually like that sound.

You might have a know issue, Mazda published, here in Europe a TSB for this last month, because of air mix doors unintentional repeat movement in auto mode, causing clicking noise.

The control software of the dash-ESU needs to be updated. TSB# R045/20. I would imagine a similar TSB would also be out for, or soon out for NA market, check with the dealer.

Exactly it is bothering me I have had it a month and at start up it revs high then goes low on tach seeming like gasping for air. I am taking it in next week . Plus I just got a survey and it was asking many questions about start up and hesitation.
