2023 CX-50 Issue: knocking sound coming from rear of vehicle at low speeds between 1mph-10mph.
I purchased this brand new 2023 Mazda CX-50 at the end of this July, and it has no incidents, no hits, no scratches at all. Last Sunday while driving it, out of no where, the 'Vehicle System Malfunction' message showed up and I dropped my car at the dealership right away. There was the weird sound from the front of the vehicle every time I braked to 10 mph, and I don't want to take risk of my own to drive it anymore. The front right-side lower active grille shutter was broke, and three lit damages were spotted on the condenser behind it. Luckily no leakage happened at that time. The dealership gave it a rounded inspection and told me 'it might be hit by a little rock'. Yeah, a little rock broke the entire grille shutter. I realize that there is no protection of any sort in front of the shutters, and it is very easy for any little object to break the shutters and the condensers as well. You can see easily from any picture of a CX50, there are two open big holes at the lower front, and the shutters are inside. This makes the shutter entirely expose. It's only two months since I bought this car, I believe I will not be the first CX50 owner that has this problem. It is highly possible that this is a design flaw, there should be some protective manners in front of the shutters to reduce the possibilities of something hitting it. Mazda's warranty is not covering this since they told me 'it was damaged by hitting a little rock', but this damage was because there is no protection to the shutter at all.
