Lemberg Law has launched a class action investigation into 2025 Mazda CX-70 Hybrid vehicles suddenly losing power on the road. It is a common problem with the 2024-2025 Mazda CX-90 Hybrid with drivers who tell horror stories about how vehicles become completely inoperable. Mazda has already issued two recalls for loss of drive power problems that affect the CX-70 model. While there are not many complaints from CX-70 owners (yet), we are monitoring the situation. Owners are encouraged to report their negative experiences.
What’s Happening with the CX-70 Hybrid?
The recalls issued by Mazda outline the issue very clearly. If you experience a loss of drive power — which the automaker warns increases the risk of a crash — this is likely to be a software error. But that’s where it becomes complicated. Descriptions of what happens when these vehicles lose drive power vary. Sometimes, vehicles simply stop running, often on highways. Often, but not always, the problem starts with multiple malfunction warnings.
Recall
Premiered in 2024, the 2025 CX-70 Crossover SUV was unveiled in the US on January 30, 2024. Labeled the “Passion Pursuer,” it incorporated Mazda’s latest safety technology. The surprise is that by October 31, 2024, the model was listed in two of the automaker’s recalls. Both of these warn that a loss of drive power increases the risk of a crash because of certain failures or malfunctions.

What the Recalls Say
NHTSA Campaign Number 24V815000 warns that 31,488 2024 CX-90 and 2025 CX-70 vehicles have powertrain control modules (PCM) and engine control modules (ECM) software that may cause the malfunction indicator lights to illuminate. There may also be a loss of drive power. Because of this, the recall states that the software will be updated free of charge.
In December 2024 vehicle owners were notified about three issues, all of which “may increase the risk of a crash.”
Loss of drive power due to software errors: The problem stems from “improper software” in the PCM and ECM. This may cause malfunction indicator lights to activate and potentially trigger a fail-safe mode that reduces drive power.
Engines stalling at idle due to software errors: The issue involves “improper software” in the PCM and battery energy control module (BECM), leading to engine failure to restart when idling after an auto engine stop (i-stop). In this scenario, the engine warning light will illuminate, a “Hybrid System Malfunction” message will display, and a warning chime may sound.
Loss of drive power in EV mode due to software errors: Affected vehicles will require the affected modules (PCM/ECM/BECM/inverter) to be reprogrammed with improved software, free of charge.
To resolve these issues, the affected modules (PCM, ECM, BECM, and inverter) will be reprogrammed with updated software at no cost to the vehicle owners.
NHTSA Campaign Number 24V817000 alerts owners that 14,902 2024 CX-90 and 2025 CX-70 PHEV vehicles are affected by inverter software issues. These issues may cause the malfunction indicator lights to activate and could result in a loss of drive power while operating in electric vehicle (EV) mode. Updated inverter software will be installed at no cost to owners.
The owner notification letter is the same.
Owner’s Experiences
Lemberg Law would like to know what owners are experiencing. Despite the recalls, so far there aren’t any complaints lodged with the National Highway Traffic Safety Administration (NHTSA) that highlight the problem. There are, though, experiences that owners of the 2025 Mazda CX-70 have shared on other platforms.
CX-70 Forum
For example, the owner of a 2025 model warns on the CX-70 Forum that its Ev mode doesn’t work in cold temperatures. “My SUV had 900 miles on it when one morning I tried to start it, but nothing happened. I called the dealer, and they came to pick it up. A week later, I got my SUV back, and they informed me it had a battery problem. I also mentioned to the service advisor that the EV mode wasn’t working. The advisor explained that this issue was due to the cold weather. I wish I had known this information before purchasing the vehicle.”
Reddit
A contributor to Reddit stated that during January 2025 that his 2025 CX-70 had “died” twice and had needed to be boosted. Asking for insight, he said: “The immobilizer was activated and the only way to get it out of that mode was with a boost. Originally I wanted to take it to the dealer but I know how these things go if you drop the car off and it’s working perfectly, they won’t find anything wrong with it and charge you for the diagnostic so I refrained from taking it to the dealer while it was running perfectly. This last time the boost did not work and the car is completely dead. The worst thing is I can’t even get towed because someone is parked in front of me (I live in a dense city with street parking).”
