Has anybody else experienced an Active Shutter failure, or am I the only one facing this issue?


Recommended Posts

Mazda USA and my local service centre have said that they have not before experienced this problem. The shutters in the front bumper of our cx30 are made of plastic. One of them was dislodged by debris on the road, which ultimately caused the engine to malfunction and burn out. Mazda asserts that this issue is not eligible for warranty coverage, as they claim its component is not defective, leaving me solely responsible for resolving the matter. Considering that I have had the vehicle for a duration of 18 months and mostly use it for regular commuting purposes, I would want to ascertain the number of further instances in which a seemingly little "pebble" would result in an expenditure of $1600.

That is unfortunate. I comprehend the perspective of the dealers on the matter, however. It is essentially the same as a rock damaging a headlight, windscreen, or any other part of a vehicle. Warranties do not provide coverage for damage that occurs while driving.

The portion consists of the shutters and a shroud to which the shutters are attached. Naturally, the shutters themselves are not sold separately; they are part of an assembly. The Manufacturer's Suggested Retail Price (MSRP) for the Mazda is $619. It is likely that a slightly reduced price might be obtained if you possess the skills to do the necessary tasks yourself.

In the near future, I want to remove the front bumper cover and put a debris screen in front of the shutters.

If you come across a debris screen that suits your needs, do inform me. I would really appreciate it. This was an option that was not made available to me, and I strongly believe that the car would greatly benefit from it.

I was unaware of the existence of this feature. That is an unconventional piece of technology for a vehicle without a turbocharger.

Incidentally, my dealer specifically instructed me to deactivate the automatic folding feature of the side mirrors during the winter. He explicitly said, "If they become frozen, the motor will malfunction." Excluded from warranty coverage. The cost is 350 EUR for each side, as indicated by a shrug.

The shutters are unrelated to N/A or turbo. When the vents are closed, they prevent air from flowing past the front of the car, resulting in increased drag and reduced fuel efficiency.

Dynamic front grilles

Active front grilles are widely used active aerodynamic features that are regularly seen on popular automobiles.

The dynamic front grille adjusts to accommodate the cooling requirements of the engine, electric motor, or battery located behind it. The system often comprises motorised fins or vanes that have the ability to either open or shut.

At lower velocities, the engine or electric components experience less strain and need little cooling. Consequently, the active grille is in a closed position, which enhances aerodynamics by reducing surface area.

At elevated velocities or in conditions where the components experience increased stress, the fins or vanes expand to guarantee the appropriate airflow for adequate cooling.

It is an impressive feature, without a doubt. However, I only referred to turbos since I believe they are more sensitive to temperatures and, in my opinion, more deserving of a function like this.

Approximately two decades ago, my father would use duct tape to secure the front grille of our family vehicle during frigid winter seasons.

Only specific trims of the CX-30 in the USA are equipped with shutters. This was the situation when I purchased mine in early 2022, which is why my vehicle does not have them. However, it is evident that the large lower front opening that the CX-30 comes with from the factory is detrimental to all trims in terms of the potential for damaging road debris to enter at higher speeds. Additionally, this design choice has an unappealing and low-quality appearance. Was your CX-30 equipped with the aftermarket do-it-yourself modification that included the installation of additional lower intake grill pieces?
