Toyota recalls 10,000 C-HR electric cars over power loss risk By Carolina Costa

Toyota initiated a global safety recall covering approximately 10,000 units of the 2026 C-HR electric crossover after discovering a software defect that can cause the vehicle to abruptly lose drive power while traveling on the road. The issue traces directly to programming errors governing the regenerative braking system rather than physical defects within the motor hardware or the high-voltage battery cells.
About 1,310 of the affected electric vehicles are located across Canada.
How regenerative braking triggers system shutdown
Trouble begins when the vehicle operates with a high battery charge while the driver simultaneously uses regenerative braking to decelerate. Under these exact running parameters, the management software allows the high-voltage battery pack to absorb excessive electrical current beyond engineered safety thresholds. Because this surge violates system parameters, the onboard computers trigger an automatic protective shutdown across the entire electric powertrain.
Vehicles undergoing this shutdown do not lock up mechanically or stall completely. Drivers instead experience a sudden loss of motive power at highway speeds, creating severe collision hazards during passing maneuvers or while merging onto active freeways.
Remedy details for affected owners
Authorized dealership service centers resolve the issue by installing a complimentary programming update directly to the Battery Electric Vehicle Electronic Control Unit. The update is free.
Toyota Canada plans to send official notification letters to registered owners by early November, though service departments can apply the software patch immediately for drivers who schedule an appointment in advance. The manufacturer has not confirmed whether this specific remedy will deploy as an over-the-air package, meaning owners must visit a local dealership to receive the correction.
Shared technology issues across electric models
The 2026 C-HR EV relies on the corporate e-TNGA architecture shared among several modern electric vehicles from related product lines:
- Toyota BZ model series
- Lexus RZ crossovers
- Subaru Solterra electric vehicles
These related nameplates already fall under a separate 2026 recall targeting high-voltage battery control logic through dealer-installed code. Drivers of vehicles built on this platform have also documented unexpected 12-volt auxiliary battery drain after leaving cars parked for several consecutive days.
Software-induced propulsion losses represent a growing industry challenge rather than an isolated incident. Jaguar Land Rover issued a similar safety recall due to software faults earlier this year, while the Volvo EX30 encountered control-system campaigns tied to battery fire hazards.
Customer verification and support contact
Safety filings through NHTSA document the battery-electric powertrain defect, allowing drivers to check individual vehicle identification numbers in the federal regulatory database once the campaign registers. Owners can contact brand representatives directly by dialing the customer service line at 1-800-331-4331.
Drivers encountering sudden acceleration drops at high battery levels can contact local dealerships immediately without waiting for postal notices.
