EXTERIOR LIGHTING:HEADLIGHTS
What Happened
The headlight system in your Jeep Grand Cherokee L has a problem: when the auto high beam setting is turned on, it won't actually turn on the high beams until you switch the master switch to the 'on' position.
Risk if Unfixed
If you're driving at night and can't switch to high beams when you need to, you'll have reduced visibility, which could lead to a crash.
Free Fix
Your Jeep dealer will update the vehicle's computer system to fix this issue, and the repair is free. You should schedule the update as soon as possible.
