2025 Mazda CX-90 PLUG-IN Hybrid

The contact owns a 2025 Mazda CX-90 PHEV. The contact stated that the hybrid battery failed to charge above 80 percent, and the "Engine Malfunction" warning light remained illuminated. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 25.

After backing out of my driveway, I put the vehicle in drive and the dash illuminated with malfunction errors. "Hybrid system malfunction", "Hybrid system electrical leakage detected stop the vehicle" and " I-activ sense partially disabled". I pulled back into my driveway, shut off the car for about 5 minutes and tried restarting. The car was disabled. Lights were still illuminated and then I couldn't get the car to move out of park. I called the dealership immediately and we arranged a tow for them to look at it. Day 2 at the shop and no answer as of yet. If my car went into limp mode and disabled my vehicle as I was driving, I could have caused an accident posing risk to myself as well as my children and other drivers. This malfunction has been happening to other CX90 and CX70 owners regardless of PHEV or MHEV vehicles. Please look into this. This is concerning with a brand new vehicle!

Purchased the car 3 days ago. Went to start the vehicle and received the critical error message “electrical leakage in the hybrid system was detected”. Car has to be towed. It appears this is an issue Mazda is fully aware of and continues to sell the cx90 PHEV. All parts are on months backorder and the problem persists after repairs according to others.

Hybrid system malfunction Critical malfunction electrical leakage detected on dash board Car died 2 times left us stranded with children Cars at the dealer for the 2nd time with same issue No warnings Happend 3 hours after picking up the car. Then again 5 days after the dealer said it was fixed. Now in dealer 2 weeks with no answer as to what the issue is. But the problem is wide spread and many people looking for answers online with the exact issue.

I leased this vehicle with 12 miles on it from Werner Mazda in Manchester NH. I drove it home 8 miles without issues parked it in my driveway and it immediately started to broadcast multiple warnings completely locking up. Was unable to move the car out of park. Flatbed had to take the car back to the dealership where they are currently working on the car. No recalls officially reported. A quick search indicates an ESU issue requiring an update.

The day after purchase, with 216 miles on the odometer, a major failure of the hybrid electrical system occurred. The car immediately shut down, not allowing the car to be moved (it could not be shifted out of "Park"). The message indicated that a high voltage leakage was detected and that the system was hazardous. It required a tow to the dealer. The dealer's service center cleared the error and refused to take further action. If this should happen again, on a busy street, serious injury could result.
