Official summary
Some customers may complain that the 2 mph rear BCM power liftgate (PLG) warning beep is too low, making it difficult to notice that the PLG is not closed properly with the front instrument panel warning lights. As the vehicle speeds up to above 6 mph, the front BCM warning beep will activate to notify the driver that the PLG may not be properly closed due to interference from rear cargo items. This is caused by the warning beep volume on the rear BCM being set too low. To eliminate this concern, the PLG control module has been modified.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
