The battery died, the car wouldn't start one night. The battery which is the original that came with the car is only about 2 years old. I googled the code from the code reader, it said some mazda cx-5 have a starting problem but then I checked the recall website and there was none.

Summary of Events: Purchase Date: 05/27/2023 Coolant Warning: In January 2025, I received a coolant temperature warning (code P0126) indicating insufficient coolant temperature. Repairs: I brought the vehicle in for repairs on 02/15/2025 for thermostat and related parts. The repairs were completed by 02/17/2025. New Warning: On 03/18/2025, I received a high coolant temperature warning. Upon inspection, coolant was nearly empty, and I found coolant contamination in the engine bay. Notification to Dealership: I emailed Hennessy Mazda on 03/19/2025, but after no response, I filed a claim with Mazda headquarters on 03/20/2025. Only after that, they called me and instructed me to bring the vehicle in. They claimed that after replacing the faulty parts and cleaning the engine bay, the car was ready for pickup. (While they assert that all actions were completed on 03/22, Based on the fact that the car door was opened approximately five times in April,...

Small amount of weight such as keys or phone is triggering the Occupant sensor in the front passenger seat. This issue just started and I am finding a lot of complaints regarding this.

The contact owns a 2023 Mazda CX-5. The contact stated that while the temperature was 45 degrees or lower, the vehicle failed to start properly, and the engine failed to warm up properly. The coolant light was illuminated, and the engine temperature gauge failed to rise above COLD. The vehicle occasionally failed to start or while started and driving at various speeds, the vehicle stalled while and engine temperature failed to reach the normal operating temperature. The check engine light was illuminated. The contact would shift to SPORT Mode to prevent the cylinder activation from occurring and causing the vehicle to stall. The contact stated that the failure persisted, and the vehicle was hesitating while driving in temperatures of 50 degrees or less. Additionally, the key fob intermittently failed to unlock the vehicle. The contact stated that the vehicle failed to start and had to be towed. The contact stated...

I love this car, but it has a bad habit, the vehicle accelerates on its own. If you take your foot off the gas, the car will intermittently lurch, almost jump forward. I’ve learned to deal with this by simply keeping a strong push on the break, but it is definitely is an issue. Another issue I’m having is the back lift gate. I’ve been told that the sensors are on each side of the gate and perhaps when drying the vehicle, I touch them😳 they run along each side of the liftgate fully visible. I have 17,000 miles on my car right now and when the lift gate opens closes it stops halfway and it beeps. I then have to push it down to close. I took it to the dealer and they say it will cost me if they have to check the sensors. This is extremely annoying...

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.

The power liftgate on the 2023 Mazda CX-5 SUV closes with sufficient force that the vehicle owner's manual warns of possible serious injury or even death, and cautions the operator to be sure that people or objects are not in the way of closure. However, the actual design of the overall system permits accidental closure by way of the key fob even when the operator is out of sight of the vehicle. This effectively renders the warnings meaningless, and disregards the safety of people or objects that might be in the way. The vehicle electronics/computer system uses dual purpose switches in or on the vehicle to activate the liftgate; if closed, a press of the switch will unlock and open it, and if open, the same switch will close and lock it. The system also provides the same feature with an exposed, raised button on the key fob which can...
