Toyota C-HR EV Recall (26TA17): Why a Battery Software Fault Can Cut Drive Power and How the Repair Works
Karmactive first reported this recall on September 12, 2026. This update covers what has changed since. Owner letters for the Toyota C-HR EV recall, campaign 26TA17, were mailed on October 19, according to the US recall record. The recall covers a battery software fault that can overcharge the battery, shut down the drive system and cause a loss of drive power. The repair is a software update performed by Toyota dealers, at no cost to owners. Here is what the recall covers, and what to know before your appointment.
Toyota is recalling 8,521 model-year 2026 C-HR electric vehicles in the US, and about 1,310 in Canada. The recall was filed with the National Highway Traffic Safety Administration (NHTSA) in September under campaign 26V570000, Toyota code 26TA17. Affected cars were built between early February and July 10, 2026. The recall covers the battery-electric C-HR EV.
The fix is a software update that a Toyota dealer performs. Toyota dealers will update the battery electric vehicle control unit’s software at no cost to owners, under recall code 26TA17. The recall says the problem can occur when the battery is already at a high charge level. Until your appointment, ask Toyota or a dealer whether any charging precautions apply to your car. The recall describes cold weather, a high battery charge level and active regenerative braking as the conditions that trigger it.
Why Cold Weather and a High Charge Trigger the Toyota C-HR EV Recall
The battery control unit manages how the battery charges and discharges. Regenerative braking recovers energy when a car slows down, by sending that energy back into the battery. The recall describes a software error that can overcharge the battery, shut down the drive system and cause a loss of drive power. The overcharging can happen when the battery is already at a high charge level and the weather is cold. Regenerative braking must also be active. For how battery warranties work, see our Chevy Bolt warranty guide.
Toyota has now recalled 29,512 US electric vehicles across two campaigns. That total adds this recall’s 8,521 vehicles to a June recall of 20,991 bZ, Lexus RZ and Subaru Solterra models, which covered a battery control unit fault that can also cut drive power. For other recent NHTSA recall coverage, see our Ford F-150 recall report.
The European C-HR+ is built at Toyota’s Takaoka plant in Japan, according to reporting. Whether the Subaru Uncharted shares that line is not confirmed. The recall documents cover 2026 C-HR EVs in the US and Canada.
The recall describes three conditions together: cold weather, a battery already at a high charge level and active regenerative braking.
