2023 Mazda CX-50

On multiple occasions the vehicle has not acceleratedfrom a stop while pushing the accelerator pedal. Have noticed this is usually on warmer days, with AC on half to full, within 3 minutes, and within 1 mile from leaving work for the day after car has sat parked. I am worried this will get worse and cause a potentially dangerous situation when turning left against traffic and the car doesn't accelerate.

Transmission Malfunction / Erratic Low-Speed Operation I am reporting a safety-related defect involving the transmission system in my vehicle. The issue appears to have originated as a software-related drivability problem but progressed over time into a more serious mechanical failure affecting the transmission. The vehicle exhibited lurching/hesitation at low speeds, particularly during city driving and while idling or creeping forward in traffic. This malfunction creates a potential safety risk because the vehicle does not respond smoothly or predictably to driver input. The erratic behavior is disconcerting and requires increased driver attention, creating a distraction and reducing confidence in the vehicle’s operation. The issue has been reproduced and confirmed by a service technician, who identified a transmission-related problem and recommended repair or replacement. The failure was not consistent with normal wear and occurred prematurely. The vehicle has been inspected by an authorized dealership and is covered under the 5 year power-train warranty. Prior to the failure, there were no warning lights or messages indicating a major transmission issue. The problem I believe has been there since day 1- initially presenting as mild hesitation that could be mistaken for normal operation (especially with a turbocharged engine), but became increasingly annoying over time. After researching the issue, found similar reports from other owners describing comparable transmission behavior, suggesting this may be a broader defect.

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.
