There are 3 owner-reported powertrain & transmission complaints for the 2023 Mazda CX-5in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Slowly and cautiously entered parking lot of a small strip mall. Proceeded to a parking space located in between two parked vehicles.Maneuvering into parking space I removed foot from gas pedal toward the break pedal; before foot made contact with break pedal the vehicle accelerated on its own surging over the cement parking bumper, over bushes, through the grass, down the curb and into the street. I jammed on the breaks. Lifting foot from break pedal I did not touch the gas pedal in fear the surge might happened again. Instead I allowed the vehicle to coast as I guided vehicle to the curb. In all the commotion, while trying to control vehicle safely I noticed the dashboard transmission indicator lights flash from park to drive to neutral. Safety issues for me and family at risk because we had no control over the acceleration of the vehicle.
When driving the vehicle, my car exhibits a rocking / shake when going from brake to gas at speeds below 20 mph. I was told by the dealership that it is normal operation, but when driving two other CX5’s, the behavior did not exhibit. I do not know what to do. I have also brought it to 2 independent mechanics and they told me the engine mounts needed to be replaced. I did the service at 36,000 miles and it did not get rid of the problem. It seems to be a defect of the car, which I’ve been living with since 2023. The issue has been ongoing.
Brand new 2023 Mazda CX-5 with 150 miles on it experienced unintended acceleration while braking. Pulled into a parking spot with my foot on the brakes but the car didn't stop & even accelerated over a sidewalk and into a building. I experienced a bruise from the seatbelt. Airbags did not deploy. Someone could have been killed if they had been on the sidewalk. Car is currently at an auto body shop to fix the cosmetic damages, and once released, will have the car towed to our local Mazda dealership/service center to get the car inspected. In doing research on NHTSA's website, at least 4 vehicles (2-2023 Mazda CX-5s and 2-2023 Mazda CX-30s) have experienced this issue. Mazda needs to recall these vehicles and investigate.
