Download Some customers may complain of an intermittent battery draw concern. This only applies to vehicles with a navigation radio and rear park assist. The radio may stay powered up if the rear park assist alarm is going off when very close to an object (continuous chime) and the ignition key is turned off before the chime cycle completes. This happens due to a Software anomaly in handling the chime. Even when the conditions are right, this is still an intermittent concern, and hard to duplicate. Recommendation/Instructions: Reprogram the navigation radio with the latest calibrations in TIS. Under the operating system there is a calibration titled “New software to correct continuous chime and potential battery run-down condition”. Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
