The car has signs of current recall in other Cx-5 Models. Hesitation with acceleration or driving at high speed, reduced power, not responding appropriately when accelerating or would accelerate on its own, strong smell of gas after the car has been driven and is parked. I know there is currently a recall for a gas pump failure. There is no engine light on.

Car “died” while idling at a traffic light. It started but would not start several hours later and car was towed to mechanic. Diagnostics “determined “after several days that car needed an ECM. ECM was ordered and replaced, along with the battery. This took several weeks, in the meantime, I had to rent a vehicle. Vehicle picked up on May 29th and driven 250 miles and car sputtered, hesitated, slowing down in heavy traffic at high speeds on highway, putting other drivers and myself in a very unsafe situation. Several days later this happened again while traveling back home, again, at highway speed putting other drivers and myself in high risk situation. (This happened several times during both trips.) As I was focused on the road, I did not see if any messages were displayed. After returning home, the mechanic was informed via voice mail and again via telephone. The following morning (June 2), the car sputtered, hesitated to accelerate at low speeds and died while driving to repair shop (battery indicator illuminated as I was pulling over). Car has been towed again to repair shop.

MY 2020 MAZDA CX-5 WAS 2 DAYS OLD AND THE BATTERY WAS COMPLETELY DRAINED AND HAD TO BE TOWED TO THE DEALER. I PICKED IT UP AND THEY DID NOTHING TO THE BATTERY. THEY TOLD ME NOTHING WAS WRONG AND THEY REPLACED THE KEY FOB BATTERY. TWO MORE DAYS AFTER THAT I PARKED IT IN MY GARAGE AND PUSHED THE BUTTON TO TURN IT OFF. APPARENTLY IT DID NOT TURN OFF AND COME MORNING, I HAD SIGNIFICANT CARBON MONOXIDE POISONING AND WAS HOSPITALIZED FOR 4 NIGHTS. MY CAR WOULD NOT START AGAIN AND THE ODD THING WAS THAT THE BATTERY WAS DRAINED AGAIN AND THERE WAS STILL GAS IN IT. MY LOCAL MAZDA DEALER REFUSES TO HELP ME AND I AM TRYING TO CONTACT MAZDA'S MAIN NUMBER.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Mazda Cx-50 verdict →
