Is there an official announcement of this recall? How can one check if their Merc needs rectification ?

If you mean a widely publicised announcement, then i dont think so. I got this letter a few days back and hence it could be on selected models, year of manufacture, or specific vendor related component. Best is to check with your service station.
Mine is a C class 2008

Seems to be the same as the recall they ran internationally in 2015. Your car is from the same build year.

Quote:
SUMMARY: Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2008-2009 C300 Sedan, C300 4Matic, C63 AMG, and C350 vehicles, and 2010 GLK350 and GLK350 4Matic vehicles. Due to a manufacturing error, the air bag control unit may corrode and cause the control unit to malfunction.

CONSEQUENCE: The malfunctioning air bag control unit may cause the air bags to unexpectedly deploy increasing the risk of injury and the possibility of a vehicle crash. Alternatively, the air bag control unit malfunction may cause the air bags to not deploy in the event of a crash necessitating air bag deployment, increasing the risk of occupant injury.

REMEDY: MBUSA will notify owners, and dealers will inspect the air bag control unit and replace it, as necessary, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact MBUSA customer service at 1-800-367-6372.

Guys i need some help with this weird issue with our 2009 C220 CDI that happened last week:

On Friday 22nd April when my younger sister was going to college the driver side window for no reason exploded while driving on the highway. Due to the sudden loud explosion the car almost got out of control but luckily was controlled before any tragedy could happen. Generally she drives herself but luckily on friday our old & trusted driver was driving who was able to handle the situation. Had my sister been driving anything could have happened.

The workshop has confirmed to us that the car's onboard computers show that there was no warning given by the car before this incident happened.

There was not a single vehicle around the car when it happened and the car was on a flyover at that time so there is no possibility of anything hitting the window.

Mercedes has responded to our complaint and sent their engineer to check the car but he couldnt find anything. We are confused as to what should be done next and are scared of this happening again or any other such freak incident. Imagine what could happen if you are driving on the highway and all of a sudden there is an explosion right next to your face and your window shatters on its own.

Along with this i should ask them to carry out the airbag fault repair as well

It does happen. Nothing to do with the airbags though. And I don't think the on-board computer can detect such an event. The glass could have been weakened by previous damage/wear and tear. Even minor damage can lead to glass breakage over the long term (apparently it all adds up - several minor damages can accumulate over a long period and break the glass).

It can be caused by many reasons:

http://educationcenter.ppg.com/glass..._breakage.aspx

It happened to my dad in his old Toyota Corolla (ages ago, sometime in the early 1990s), the driver's side window suddenly shattered as we were driving, and as far as I can recall no fault could be found.

Back to the thread topic - about the recall, seems to be related to the 2015 recall due to the same issue; the models involved were sold between 2006 and 2008.
