the problem: a correctly fastened seat belt may be inaccurately detected as being unfastened, preventing the seat belt pretensioners from activating in the event of a crash, increasing the risk of injury.

the fix: dealers will replace the seat belt buckles for free.

what owners should do: mercedes-benz will begin mailing interim letters to owners jan. 25; a second letter will be mailed once remedy parts become available. owners can call the automaker at 800-367-6372, the national highway traffic safety administration's vehicle-safety hotline at 888-327-4236 or visit its website to check their vehicle identification number and learn more.
