Toyota is recalling approximately 10,000 of its 2026 C-HR electric crossovers in North America due to a software issue that could cause the vehicles to lose power while driving. The problem stems from the Battery Electric Vehicle Electronic Control Unit, which can overcharge the traction battery during regenerative braking when the battery is already full.
The automaker states that the software flaw causes the system to overcharge the traction battery under regenerative braking if the state of charge is already high. Regenerative braking uses the electric motor as a generator to slow the car and return energy to the battery. When the battery is full, safety systems should prevent further charging, but this is not happening in the affected C-HRs.
According to Toyota, updating the control unit’s software will resolve the issue. However, the fix requires a dealership visit, which the company acknowledges is unusual for a modern electric vehicle expected to receive over-the-air updates. The 2026 C-HR utilizes an older infotainment system compared to Toyota’s newer Arene setup, and features a slow-to-boot 14-inch touchscreen with Apple CarPlay and Android Auto.
Despite the limited tech features, the C-HR has contributed to a 136% increase in Toyota’s U.S. EV sales in the first half of the year, alongside the updated bZ and new bZ Woodland models.
