Service bulletins for the 2026 Toyota C-HR
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| T-TT-0806-26 | 2026-08-12. Service bulletin. ENGINE. State of Health (SOH): An estimate of battery health that is updated as the vehicle learns from operating and charging conditions over time. Distance Since Last Update: Indicates the distance accumulated since the last SOH calculation. A default mileage value of 40,727 at SOH 100% may be displayed until sufficient vehicle learning is completed. Once SOH value updates from 100%, the Distance Since Last Update value will re-set to 0 miles. Both SOH and Distance Since Last Update values will continue to update as the vehicle continues to learn. |

| T-SB-0040-26 | 2026-08-12. Service bulletin. ENGINE. Some 2026 model year bZ, bZ Woodland, and C-HR BEV vehicles may exhibit the Diagnostic Trouble Code (DTC) U255221F associated with the level 3 DC fast charging. Under certain conditions, charging may either operate normally or experience failure, with a charging malfunction message displayed on the Multi-Information Display (MID). This condition is attributed to a control logic issue and potential voltage drop affecting Plug-In Charge Control Computer Assembly functionality. The control logic has been modified to reduce the possibility of this condition. |
