NHTSA recall 12V533000

What's wrong: The bolts that hold the hood's secondary latch striker may have been insufficiently tightened.

Why it matters: The reduced torque of the striker bolts might lead to a loosening of the bolts. If two of the four bolts securing the striker became loose, the secondary hood latch function would become ineffective. If this problem combines with a failure of the primary hood lock or if the hood is not properly…

The fix: Mercedes-benz will notify owners, and dealers will check and retighten the bolts as necessary. Mercedes-benz notified the owners by phone for this campaign starting on 11/21/2012.
