NHTSA Complaint #11699571 — 2023 MAZDA CX-9

If you press both the brake and gas at the same time (even if accidental), the onboard computer apparently thinks that the driver is confused, and it sets the gas flow to “idle”. The first time this happened was on the freeway, and I was very lucky to be able to coast into a gas station (thinking that I simply running out of gas - even though the gas gauge showed plenty of gas remaining). And so, I took it to Christian Brothers automotive the next day, and they ran extensive (and expensive) diagnostics. They found (to their surprise!) that this is the way the latest CX-9 works! The computer sees that you are on the gas and brakes, and so it “thinks” that you must be confused. And so, it sets the gas to “idle”. I believe this is an extremely dangerous action for the computer to take, and this behavior needs to be removed from all CX-9's IMMEDIATELY! And please don't just say (as others have) that the driver "shouldn't press both the brake and accelerator at the same". One might use the brake and accelerator at the same time for good reason, such as an icy road. But the computer SHOULD NOT DECIDE ON ITS' OWN TO SET THE THROTTLE TO IDLE!
