The Toyota C-HR+ has a minor issue in the United States. Regeneration can overcharge the battery, causing the drive system to shut down.

The Toyota C-HR+ is an electric C-segment crossover sold in the United States as the Toyota C-HR, although it is only loosely related to the original C-HR. Toyota’s U.S. division has just announced a recall for this model because the software does not limit regenerative braking when the battery is fully charged. This can result in overcharging the battery and shutting down the powertrain.

Toyota C-HR+ and the first service campaign

As noted by Car and Driver, Toyota has announced a recall covering “some 2026 model year Toyota C-HR+ vehicles,” approximately “10,000 units,” which roughly corresponds to all units sold in North America, according to American journalists. This time, the news is also significant for us, as the Toyota C-HR+ is manufactured at only one plant in the world (the Takaoka Plant in Japan) and from there is shipped to all continents.

According to the manufacturer, a software error causes regenerative braking to send energy back to the battery even when it is fully charged. This results in overcharging, and since Li-ion cells are sensitive to excessive charge levels, any reasonable BMS will cut off the power supply in time. The same applies here: the risk of overcharging the battery leads to the disconnection of the drive, which “increases the risk of accidents” at higher speeds.

The advantage is that the car will at most stop by the side of the road. All electronic devices should still work inside it, as they are powered by a 12 V battery. The downside, however, is the scope of the recall action. Specifically, “some,” around 10,000 Toyota C-HR+ models sold in North America will need to go to dealerships for an update to the battery control software. There is no possibility of remotely uploading the fix; owners will be notified, and the issue is expected to arise “by early November 2026.”

Editor’s note from Elektrowozu: We advise owners of the Toyota C-HR+ to temporarily minimize regenerative braking when the battery is charged above 95 percent or when leaving Zakopane with a charge level over 95 percent.
