5.30 Exterior Lighting

Issue Category Widespread Level Synopsis of Reported Failures

EXTERIOR LIGHTING High Common complaints include condensation building up inside tail lights, obscuring them from view. Other issues involve the turn signal creating excessive glare on the side camera at night, making the blind spot view unusable, and a software change removing the automatic activation of headlights with wipers.

Illustrative Complaint Summaries:

• [1736351] The brake light builds up condensation, obscuring the light from being seen.
• [1785653] The turn signal causes excessive glare on the side repeater cameras during nighttime use, making the driver unable to properly view the blind spot camera feed.
