seatbelt pretensioner recall
M-B sent out a couple of weeks ago a notice to "certain MY 2017 C-Class, GLC-Class and S-Class" owners advising that "the front seatbelt pretensioners may not function properly in the event of a crash." This letter caught up with me while in New England away from DC's July heat and humidity. Since I am 500 + miles away from home for another month and "the parts to remedy this are not currently available," I'll just drive gently for a while--easy to do as the highest legal speed on the island of my current residence is 45 mph. Of course, I do have to get home eventually.
I found a posting by a C-Class owner who says that the problem is that "the propellant mix ratio...[in the affected vehicles's pre-tensioner igniters] might not meet the manufacturing specification." My letter from M-B didn't give that detail, but as this seems a relatively minor problem I hope its accurate. My letter said that the remedy was to replace the front seatbelt. Interesting that they can't just replace the ignitor.
Is mine the only GLC affected?

I received the letter too but the wording of "increasing risk of injury or death" is quite concerning. I've emailed my dealership for more info in terms of likeliness of it failing but haven't heard back. I don't drive this car as much right now as it's my winter/outdoor adventure vehicle but it would be nice to have a peace of mind when driving at highway speeds.
