# Service bulletin 0805022

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.

- Type: Service bulletin
- NHTSA id: 10223169
- Published by NHTSA: 2022\-10\-17
- Manufacturer's number: 0805022
- Manufacturer's date: 2022\-03\-09
- NHTSA component: ELECTRICAL SYSTEM:BODY CONTROL MODULE/BCM

## NHTSA's summary

Flash: Body Control Module \(BCM\) Updates This bulletin involves reprogramming the BCM with the latest available software. The customer may experience one or more of the following: Fuel Level and Range \(distance to empty\) \(DTE\) will both increase after sleep cycle. Fuel Level % would increase when parked on a slope. Fuel gauge remains at full for 107 km \(67 miles\) vs. 73 km \(45 miles\). After fueling up with 68 liters \(18.1 gallons\) of fuel, the fuel gauge only will read around 1/4 tank and the low fuel lamp is still illuminated. After 10 minutes of driving, the gauge only read around 3/4 tank and the fuel lamp is still on. Refuel button is pressed for a short duration of 500ms or less at key off, then the fuel door is not opened. When the phone is charging on the Wireless Charging Pad Module \(WCPM\) and the fob is near, the customer opens then closes the liftgate, the IPC will pop up "key fob has left the vehicle" message. On vehicles equipped with Electronic Steering Lock \(ESL\), it requires 3 Start/Stop button presses to transition from key off to key run when the vehicle was in deep sleep.
