I thought airbag activation had two triggers: a sizable acceleration/deceleration as well as actual crumple sensors. I’m not a car guy but I can’t think of a scenario that would cause the systemic activation like that. 

it is supposed to take multiple sensors including accelerators yaw sensors and impact sensors to trigger a deployment

Yup, normal operation is multi-sensor. Unless the control module is shorted. Had a vehicle that was REAL strict about sensor input to deploy to the point people wanted to sue for lack of deployment. Their control module sitll had a HUGE warning about battery disconnect and cap discharge before removing the wiring harness because you could trigger ALL the airbags.

If you are going to be in the market for an affordable and reliable used car I highly recommend the last generation (2004 - 2008) Pontiac Grand Prix.  They have the very reliable 3800 engine under the hood.  "Bullet proof" is a term you'll hear often associated with the 3800.

Low mileage ones can be found for around $5k or so depending on miles, trim level and options.  

Again, glad you are okay.  Keep us posted as to what MB says and does for you.

Car is a 2000 Mercedes E320 4matic wagon, with around 150,400 on it.  Transmission had not been acting up prior to today, so really no clue, if it even was the trans.  At first, I thought I had either a tire blowout or a rim had come apart, but all 4 are intact and holding air.  I suppose it's possible a diff went, I know too little about cars to guess much beyond that.  No fluids anywhere though.  I had it towed home instead of a shop - no reason since I'm considering it a total loss.

 

Scary - yeah, that's an understatement.  I'm glad more than anything that the airbags didn't knock me out....going 55 with no driver and no airbags to go off again would be...unpleasant....  It is also difficult to see out of the now much smaller viewing areas...I was glad i was already safely changing lanes when it happened.

 

Amazingly, no new underwear needed.

probable driveshaft couplings. they're not u-joints on mb....they're thick rubber. sorta like the rag joint on older steering shafts.

 

 glad you're ok.

Honestly - it's an 18 year old car so they'd be like "Meh buy a new one you cheap bastard" :D

 

Recalls happen on old cars all the time. Like the chassis replacements on tacomas.. not THIS old, but certainly older.

Regardless, that should NOT happen, im sure we can agree on that, lol. The OP is a champ. Id have shat my pants and crashed into something for sure!

Correction; the tacomas and tundras were the same age and older, and they spent more than the vehicles were worth fixing them or buying them back, IIRC.

That's exactly right (I have a 2002 AMG).  You'd know they were failing (usually slowly) if you have a 'clunk' when you shift into reverse from park or vice versa.   It's not impossible that the front flex joint came apart suddenly.

Your 2000 is too old to be affected by the Takata recall.

Sorry this happened to you!  Please let us know what you find out.

Ah, Mercedes electrical gremlins...I remember them well.  I had a 2002 C230 Kompressor-widely acknowledged as one of the few true lemons made by Mercedes.  During the 36 month warranty period, it was in for service 36 times to address electrical system problems, with only a few being repeat problems.  Then the warranty period ended, it ate two automatic transmissions in a matter of months, and I limped in to a Mazda dealer in the only gear still working, with the car alarm blaring (the dealer couldn’t silence it) to get what little trade in value I could.   I’ve never been so glad to get rid of a car. 

And I don’t think my experience was as bad as the spontaneous 7 airbag deployment the OP experienced!

    • I definitely would recommend that anyone who is serious about competition shooting to train with DVC performance. Aaron always takes the time to explain new concepts and techniques. He doesn't rush through things. He makes sure that you have a solid foundation to build on. When I went his class, he corrected many bad habits, that I had picked up while shooting without guidance. These habits, even minute one that many of us don't really think about, can cost seconds on the timer. You want a instructor who can spot errors in your shooting stance, grip ,etc and correct them so you can be a better shooter . Aaron is definitely has the attention to detail you want in a shooter instructor. Since then, I've seen a noticeable improvement in my shooting ability. He also sent me home with various drills so that I can practice on my own.       
    • I posted this in the Formal Instruction thread, but it seems to have gotten lost there.  Thought some might find this interesting, or perhaps even helpful. Hope cross-posting is not a punishable offense.   I just spent a few days up in NH at Sig Sauer Academy over the weekend.  Took their one day Defensive Handgun 104, which was relatively basic, but a good review, particularly in one-handed weapons manipulation. The other class I attended was a two-day Extreme Close Quarters Battle Long Gun with Todd Rassa, which I really enjoyed.  I ran it with a Ruger PC9, a shotgun, and an AR.  It involved a lot of unsighted shooting from contact distances using compressed positions, plus it incorporated a good deal of armed and unarmed combatives.  It was more about fighting with a gun than it was about what we normally think of as shooting.  Despite my doing a lot of training, most of it was new to me and quite interesting.   Here's their description: https://www.sigsaueracademy.com/productdisplay/extreme-close-quarters-battle-long-gun-rassa I had not heard of Rassa before the class, but it turns out that he is a terrific instructor.  I would recommend SSA in general, as they offer a ton of classes.  Just wish they were a little closer.  On the upside, with a NH CCP you can carry the whole time you're there.  Note:  Turns out you don't even need a permit to carry there, as NH has gone Constitutional Carry.  God bless America!
    • If you want to a better competition shooter than you need to go to DVC and not a tactical shooting group.  I have trained and shot many matches with Aaron.  He knows the game and what it takes to excel.  Not just the shooting portion, which he will get perfected for you, but the stuff that wins matches, stage break down, movement,  where to save seconds, 1/2 seconds, tenths of seconds.  This is what wins matches, this is what makes you a great match shooter.  You want an instructor that knows this.  Few do, but Aaron does and he will show you that on the shot timer.  
    • I was there 2 years  ago and a drunk dude ran past security and climbed the fence the overhangs the track. He was siting with one leg dangling over the edge of the fence as cars flew under him at 100+ miles an hour. They didn’t even call a caution
