What 47 owners told NHTSA about the 2025 Mazda Cx-70 Mhev

While driving at a speed just under 45 mph, my Mazda CX-70 suddenly displayed and chimed “Hybrid System Malfunction. Have Vehicle Inspected.“. This warning startled me because I am familiar with issues since I had briefly owned a CX-90 PHEV the first year this model came out and it had the same exact problem. I discovered that this issue carries serious safety concerns and ended up convincing the dealer to swap the vehicle for a CX-90 inline 6 gas only model after hours of pleading. I ended up signing up for another lease a couple of years later with this current CX-70 PHEV, as I was told that the “bugs” have pretty much been worked out so I would give it another try. This warning continued to stay on as I drove for a few minutes so I immediately took the car straight to the Mazda dealership service department where it was kept 24 hours. The dealer said that the issue resolved itself - something to do with not driving the vehicle interchangeably enough between gas and EV mode. The photo was taken once I slowed down to stop at an intersection since it took me 15 minutes to drive to the dealer.
