One problem related to turn signal has been reported for the 2010 BMW X5. The most recently reported issues are listed below.
After changing the battery, the vehicle has no operating dash lights, gauge indications, turn signals, or bright lights. Additionally, the windshield wiper continuously swipes, but has no ability to spray washer fluid or change the speed of the swipe. These conditions render it difficult to drive and see through the windshield, especially at night, and prevents the operator from monitoring the vehicle, identifying ones speed, or signaling a turn. Moreover, the continuous windshield wiper action impairs one's ability to see and is also distracting; making it dangerous to drive the vehicle.
