The major issue that happened to our newly purchased CX 90 last February 3 with more than 500 miles on it started around 5:30 pm of February 8, while my wife is driving this vehicle with my daughter, all of a sudden the car stopped at the middle of the road with warning signs popping up in the dash screen like I-active sense malfunction, hybrid battery malfunction, engine malfunction light on, and on top of these, critical vehicle malfunction. The car won't start and disabled. Also, the vehicle cannot switch to neutral gear to push/pull the vehicle to the side that made the vehicle blocking the roadway until the tow truck came in. My wife and daughter's life was put in danger when this vehicle suddenly stopped in the middle of the road with cars passing by on both ways. I also found out based on the NHTSA vehicle safety, Mazda recall website, carfax and Kelly blue book, that this particular vehicle with its VIN has a SAFETY RECALL due to its steering issue that may increase risk for crash. This was not disclosed to us when we are on the process purchasing this vehicle and they did state inspection and passed it that made we doubt how did it happened.. The vehicle is now with the dealership repair shop and the last update I receive was the technician is still checking on it.

On 02/07/2024, malfunction prompts displayed on my dash relating to I-stop functionality, hybrid functionality, engine. Took the vehicle the next day to be diagnosed, the appointment was set as an inspection with oil change, filter change, and the prompts on my dash. I was advised that the issue to the prompts stemmed from the hybrid battery. I was told that contact was made to the manufacturer and that the battery would have to be replaced. The battery is on backlog and it would be about a month to arrive. I called in after leaving with additional questions as to the safety of the vehicle with the hybrid battery problem. The man on the phone said it is safe to drive, what would be affected would be the mileage I would not get because the hybrid portion was not functioning. He mentioned that a separate case was created with another 2024 cx-9 car owner with the same hybrid battery issue. It-??s now two known cases with the hybrid battery issue. I called customer service and was provided with case number 00174049. The resolution to that call to corporate customer service is that I would receive a call back from the local dealership about a loaner car with about an hour. I became aware of a fourth recall, that the corporate agent referred to as a campaign, pertaining to the steering wheel. I asked my dealership advisor if that can be looked in addition to the other issues. She stated that she could not because it has not been launched. The corporate agent advised me that notification would normally happen 2-3 weeks. I looked up the steering wheel recall on the dep of transportation website. The recall has been published since the 18 of Jan 2024 and have yet to receive notification. I only found out today when I took the vehicle in for inspection.

CX90 PHEV Premium Plus new purchase 12/2023. 1/24/2024: "Hybrid System Malfunction, Have the vehicle Inspected " On a busy freeway with big rigs and other cars during rush hour traffic (5:25pm), going about 70 MPH. Only 1700miles on car so far. 50-60 degrees Fahrenheit outside. 2mi left on charge, full tank of gas. Car completely unable to accelerate all of the sudden on busy highway once this light came on. Was able to pull off to shoulder, albeit challenging as unable to accelerate and navigate through fast cars in right 2 lanes. Was able to restart car, and go at limp speed but unable to get fast enough to merge back. Called tow truck. Car towed to Mazda dealership. Then unable to get off flatbed of the tow truck as would not go into reverse. Tow guy called me and the staff at Mazda called their Service Manager, had to reset that code. (Something glitch kicked in and locked the car from being able to shift gears). Mazda Service was responsive, worked on and got diagnostics the next day. Stated that it was a computer system glitch. So they restarted the whole system. light is gone and car drives during their testing. They can't explain it. So computer and electronic glitch and system misread leads to a MECHANICAL malfunction that stops the car to be able to be accelerated on freeway. I am a mom of 3 young kids, and lucky I am alive.

During normal driving conditions going down a state highway, the vehicle lost speed with adaptive cruise control enabled. Noticing the vehicle was losing speed, I depressed the accelerator pedal. The accelerator pedal was unresponsive and unable to accelerate, I had to maneuver off the highway. Luckily, the car behind my vehicle was far enough behind me and my vehicle was going fast enough that I was able to coast to a safe stop on the side of the highway. A message popped up on the instrument cluster screen informing me to shift the transmission to Park in order to use the accelerator pedal. If this had happened on a road with little to no shoulder, the vehicle would have come to a sudden stop with nowhere to maneuver to. This would have created a dangerous situation for me, and any vehicle directly behind me. I then parked the vehicle on the side of the highway and with the vehicle still on and engine running, I again tried depressing the accelerator pedal. Again, there was no response from the pedal. I then turned the vehicle off, and restarted the vehicle. I was finally able to use the accelerator pedal and returned to the highway and my drive. The dealership was contacted a few hours after the incident, and the vehicle has yet to be inspected or problem reproduced. The vehicle is a 2024 MY and has been owned for only one month. Unfortunately, this incident is only one of five total electrical issues I have had with this vehicle. This was the most important issue to report because it involved my own safety.
