Hybrid system on other CX-90 years
No other CX-90 model year has enough reports of hybrid system for a sheet of its own. See every CX-90 year.
What this problem usually is
These reports come from hybrid, plug-in and electric vehicle owners whose car put up a system warning and lost power, sometimes dropping into a reduced-power mode on the road. Others describe a car that won't charge, a high-voltage battery or inverter replacement, or a problem that turned out to be the ordinary 12-volt battery all along.
What got replaced
Owners who name the part that was replaced mention the charger or port (3 reports).
Recalls and investigations
6 recalls on the electrical system cover the 2024 model year. A recall on the same system isn't always the same failure, so read the defect text.
The fuel gauge in the instrument cluster may display an inaccurate fuel reading.
The engine may not restart after the idling stop feature (i-stop) turns off the engine due to a software issue.
During vehicle startup, the defroster, seat belt warning, 360° view monitor functions, and the PHEV high-voltage battery cooling system may not function properly.
The powertrain control module (PCM) and engine control modules (ECM) software may cause malfunction indicator lights to illuminate and a loss of drive power.
Improper inverter software may cause the malfunction indicator lights to illuminate, and a loss of drive power may occur while in electric vehicle (EV) mode.
Due to a software error, the engine and electric motor may shut down unexpectedly, which can result in a loss of drive power.

When it happens
Too few of these reports state a mileage to give a range.
Is this a known problem?
The manufacturer has sent NHTSA 5 service bulletins or notices for the 2024 Mazda CX-90 that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
DESCRIPTION Some vehicles may experience the warning message "A 'Hybrid System Malfunction. Have the Vehicle Inspected' and DTC P2BC5:00 (OBC contactor (+) stuck ON) and/or other DTCs listed below may be stored.
Some vehicles may experience the CHECK ENGINE light ON and the message "ENGINE HYBRID SYSTEM AND i-STOP MALFUNCTION" displayed in the instrument cluster with one or both of the following DTCs: P0DAB:17 is set in the MHB module.
After an HV inverter replacement, there is no instruction in the WSM to perform Initial Learning of the Electric Motor Speed Sensor. This is required after replacing the inverter or electric motor.
Some customers may complain that the normal charge connector is stuck in the charging port and cannot be removed, or that it is difficult to disconnect.

If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
