2024 MAZDA CX-90 PLUG-IN HYBRID Complaints

On July 15, 2024 this vehicle at 50 mph on cruise control suddenly flashed white warning words indicating problems with the cruise control and immediately thereafter started flashing “hybrid malfunction” and to return to service dealer. At the time of the hybrid malfunction warning which was right after the quick cruise control warning, the engine operation, specifically the gas pedal no longer delivered power to vehicle, either electric or gas. Additional warning was to pull off to the side and stop and turn off vehicle. This occurred and vehicle was pulled to the side put into park and turned off. Waited approximately 3 to 5 minutes and restarted the engine which started in gas with no electric although there was electrical charge on the battery. Was able to continue to our final destination approximately 15 minutes later and no more than 10 miles driven. Hybrid malfunction was still visible on the dash to include the warning stating that vehicle needed to go to the service department. Approximately an hour later, vehicle was turned on again with the same warning about the hybrid malfunction, however, engine started in electric. Drove vehicle to dealership and stated what happened. Dealership the next day stated that this was a phantom code known by Mazda, but no problems associated with the code. Vehicle picked up per service advisors request two days later. Mazda dealership stated that headquarters had eyes on this particular vehicle. A day later after the pick up Mazda dealership requested vehicle be brought back for a “DC box” repair. Dealership stated this process would take a week or thereabouts to replace this component. Vehicle currently in dealership service.

I was driving 65 mph and the hybrid system malfunction warning came up. Car dropped to 25mph - pressing the gas pedal would not increase the speed. Continued to coast with no acceleration until it came to a stop and shut off

4 weeks ago my wife was driving on a busy highway and lost propulsion. Hybrid System malfunction message. She was able to pull over before causing an accident and put the car in gas only mode. She never shut the car off and drove on to her destination. I met her and picked up the car and took it to the dealer. Car is new and has 5000 miles on it. Car has been at dealer for 4 weeks with no answers and several unanswered phone calls to customer service at Mazda Corporate. Been told that is is a software problem with no fix and no time frame of when there will be a fix. I do have a case number with Mazda. Today after threatening calls to invoke "Lemon Law" in my state Mazda has suddenly said that the car has a faulty inverter and that the part is available and will be replaced. My feeling is that they are just throwing parts at a problem. This car is unsafe and NHSTA should put pressure on Mazda to either resolve issue or buy back cars. The majority of the complaints listed here are the same. Please take action!!

My car senses a vehicle in a lane to the left or right of me as a vehicle in my lane and slams on the breaks. There is a recall on this with Mazda, but not for my manufacturing date yet. It's very dangerous. Occurs all of the time

The fix done as part of remedy for NHTSA Recall #: 23V-718 didn’t actually fix the issue. In fact, I feel the frequency of blacked out 360 view monitor is increasing. Below are the details of the recall related to the same issue. Mazda Recall #: 6223J NHTSA Recall #: 23V-718 Recall Date: 10/26/23 Recall Repair Status: Repair Completed

At highway speeds on a few occasions when traffic I slowing vehicle appears to continue to accelerate for 1-2 seconds after removing foot from accelerator almost causing accident since traffic ahead is slowing.

On several occasions vehicle while in EV mode has lost all propulsion at highway speeds creating an unsafe condition.

When cruise control is active but slower than set speed vehicle will full throttle acceleration to get to set speed creating a situation where loss of control of the vehicle partially occurs. If this happened in wet or winter conditions loss of vehicle control is very possible.

Blind spot warning system gives false alarms repeatedly when no vehicle or obstruction is present. System is completely unreliable and creates an unsafe driving situation.

Car suddenly, unexpectedly, and without warning lost power while driving putting us at risk for serious collision/injury with inability to drive the car and then gave "Hybrid System Malfunction" warning. This occurred AFTER performing the recall which was supposed to address this issue.
