TSB18540052018-09-04. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM; EQUIPMENT:APPLIANCE:AIR CONDITIONER; SERVICE BRAKES. This is a Technical Service Bulletin sent to dealers, instructing them to reprogram affected vehicles' sub-BMU with updated software. Due to inappropriate programming, the sub-BMU may falsely judge the leak detection circuit as faulty by picking up electrical noises from operation of the drive selector, brake application, or air conditioner operation. This may cause several malfunction indicators to illuminate, including: Engine Malfunction, EV System Service Required, and RBS (Regenerative Brake System), with Diagnostic Trouble Codes (DTCs) P0AA7 and P0AA8 (Leak Sensor Detection Circuit). This condition is accompanied by a decrease in vehicle power and vehicle speed being restricted to maximum of 37mph (60 km/h).

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
