Exploding Headrest

Today, while driving my son and his friend to the park, I was suddenly struck in the back of the head by my headrest. I pulled over and stopped my car and could see the headrest on my 2010 GLK 350 had literally exploded? Has this ever happend to anyone???

These headrests have airbag explosives in it as part of the Neck Pro feature to help prevent whiplash in a collision. Odd that it did that out of the blue, though?

As the NECK-PRO is an electronically controlled spring-based system, it might have been activated by a spurious impulse, triggering only one of the two headrests. Or most likely caused by the "mechanics" of the headrest in question by itself.

I've never heard of it "activated by itself" - until now.

Years ago I saw a comic that likened airbags to a shotgun, loaded and pointing at you at all times.

Guess yours went off...

Exploding head rest update

The Mercedez dealership has had my car for 3 days now. They are saying that they need to have an engineer look at it to try to figure out why the head rest exploded hitting me in the back of the head. I was going no more than 15 mph and didn't experience any kind of bump or impact? I don't have confidence in my car. What if it happens to me again on the freeway? My neck is still sore and I have tenderness where the head rest hit. If this is a safety mechanism that is suppose to deploy in an accident... I don't know if I want something hitting me in the back of my head that hard while trying to avoid getting smashed in the face by a deploying airbag from my steering wheel?

Did anyone by any chance use a mobile phone at the time of the incidence, or are you aware of any (transmitting) antennas in the area?

According to what GLKK posted it's a spring loaded mechanism not an explosive.

This would not be the first time I've been told incorrect information from a tech. What the other member posted sounds more plausible.

Having had the unfortunate experience of being in a head on collision I can tell you that the airbag catches you and as the impact throws you forward then back the idea of the head restraint is to have it move forward before your head come back which in theory is supposed to prevent additional injury. The fact that it moved forward while your head was stationary is unfortunate. Hope you are OK and never have to rely on the great safety features built into today's MB's

Now you have me paranoid about RF in the car. I am a ham operator and see myself putting radio transmitters in my new GLK. Never mind the miliwatts from a cellphone. I mean 100+Watts from a low band transceiver. Yeah, time will tell.

Is this a standard feature or an option? Do all GLK's have it? How do I know if I have it?

Given your question is with regard to the NECK-PRO (and not the RF in the car ), then yes: it's a standard feature - even in your GLK.

Headrest Exploded

My 2010 Glk headrest exploded and was not preceeded by any accidents, bumps etc. I am seeing that others have posted that this has happened to them as well. Has anyone recd a response from Mercedes on this very dangerous flaw? How do I reset the headrests now that they are popped open??

Both are 2010 GLKs based on this forum. It would be helpful to know the build date to know if perhaps there was a bad batch.

350 GLK, C280
My wife's C280 had a slight hit in the rear and the headrest popped. I tried the tool using the technique in the manual and could not get it to reset. When the vehicle was repaired by the dealer, his tech's could not reset it either, but this was back in 2007. They had to call in MB specialist as this was the first they had see this. By now, I am sure every MB dealer has seen this and knows how to reset but there is a special technique and not well explained in the manual. Fortunately for me but unfortunately for you this has not happened again so I don't know the technique. However, a dealer should be able to reset this in a few minutes.

Same thing happened on my 2010 GLK. I reset it and it popped again. I haven’t reset it again as it scares the crap out of you when it goes off. I can hear it clicking periodically now when I drive.
