Dash AirBag deployed spontaneously
 

I can't believe what just happened, I was cleaning out my car this afternoon. It was sitting running in my driveway and I was sitting in the passenger seat with the door open and my legs outside the vehicle when the passenger side airbag suddenly deployed.

It hit me full in the side of the head and shoulder knocking my out of the vehicle onto the ground beside the car stunned and dazed.:eek:

The windshield is also smashed and the rearview mirror is busted off.

I can't imagine what triggered it to go off sitting still.

Needless to say I am shocked, disturbed, and not very happy right now. As well I have quite a stiff neck and a slight head ache thanks to the wallop I took.

Has anyone else ever heard of such a thing happening:confused:

This is going to be a interesting insurance claim. I wonder what the chances are of them repairing it versus writing it off?

I don't know if the insurance company will do anything. I have often wondered if I should drive my car into something if something like that ever happened to me. I would definately report it to someone like Volvo, Attorney General's office, etc. I would also recommend you go to the hospital to get your spine checked out. Could have a fractured neck that could get worse if you don't get it treated properly. You have whiplash and that could get worse.

Really sorry to hear that happened. Maybe the dealer will look the car over to see if there is some kind of problems with the wires or something that may trigger a recall to help others.

I would be very shocked if this turned out to be a SRS component/system/design failure; these things are designed to be extremely fail safe (for obvious reasons).

Most likely someone did some aftermkt installs/repairs that compromised the SRS wiring and that led to this mishap; that would be my guess...

There was a recall of some S70 models for this exact problem. Most affected vehicles were '98s but since the recall didn't come out until September of '99, there are probably some '99s that were affected. Volvo determined that the passenger airbag assembly in these vehicles wasn't adequately grounded, and so they added an extra ground strap. The deployments were caused by electrostatic discharge into the airbag module... exactly the sort of thing that occurs when you're sitting partway in the car and partway outside... this is why they tell you not to get back in your car at gas stations. Your legs were grounded outside, there was a static charge built up in the airbag, and when you touched something that was electrically connected to the airbag, you completed the circuit. Since your car is a '99, it would be interesting to find out if the additional ground wire was present, and if not, why. Was the car ever in an accident before, and had the airbags replaced? if so, did the shop that did the work maybe "forget" the strap? Or did Volvo's fix not fix the issue 100%? The ground strap is a wire with ring terminals on both ends. It should be attached to a specific body ground point- there's other ground connections there- and the other end goes where the bolt closest to the passenger door on the airbag unit is. The official fix replaces the bolt with a stud, to which you attach a nut securing the airbag, and then the ring terminal from the strap goes on next, followed by another nut. Look yourself, or have an independent mechanic look, and see if the ground strap is present. Keep in mind, it's possible that production changes made that ground unnecessary, but for now, since that was the fix for the recall, I'm assuming that that was also added to production. Anyhow, here's the dealer letter that was sent out to all dealers after the recall was issued:

wow.. sounds scary, any pics to show how it should look if the recall was done properly? i've got a 97 model...

Carrots I can't thank you enough for pointing this out. I will be having a discussion with Volvo tomorrow and talking to the local dealer service manager as well regarding this matter.
How much you wanted to bet this 99 does not have the additional ground strap?? Needless to say I am out one car at the moment.
Right about now I wish I had my old simply but reliable and safe 740 still in my driveway.

By design, during deployment the airbag bounces off the windshield, and breaking the windshield in the process. Like rspi said the first thing to do is to get checked by a doctor.

Windshield and airbag can be replaced very easily and reset by the dealer. Dealer will most likely pull you the book for service intervals of the SRS.

That is crazy! it would be awful if that happened to me. I want to check my car now to see if it has this additional safety ground strap. Where is this located? Mine is an early 98. I had the dealership print off it's warranty/service history from Volvo and it had been in the shop a handful of times for various problems in 99 and 2000. I'd think they would have done it but not sure.

If it was in your driveway somtimes homeowners insurance can compensate you as well. It would include some sort of personal injury protection through Auto or Home insurance I'd imagine should you have some medical bills (hopefully not...)

Interestingly enough I noticed on my car that there is a sticker in door jab with SRS system service interval dates. I've never heard of a SRS system being serviced (I'm guessing it's more of an inspection) but I wonder if they would hold that against you....

Owner's Manual specifies that 2 airbags and 2 seat-belts and their tensioners should be replaced every 10 years, while wiring/connectors should be inspected every 10 years. This work should be performed only by an authorized Volvo dealer.

If this wasn't done in the last 2-3 years (1998 V70), owner is on the hook....

Volvo... known for their safety. Mandatory expensive airbags replacements. What a rip off.

I haven't heard of any other manufacturer requiring that. After 10 years your safety system should be assumed useless, unless you need ejected from your vehicle when idling in driveway.

I am not sure if you are the original owner. I am not. What I don't like about Volvo is that there is no simple way to update Volvo's database that I am the subsequent owner of a pre-owned Volvo and I should get all new / old open recalls. With others, you go to a website, put in your VIN and address and get settled...

Ya it kinda sucks. Volvo is saying it's outside the serial number range of the recall, my insurance company has declared that since there was no outside forces at play they are denying coverage and Volvo wants over $2700 for parts along excluding windshield.
I have not seen that statement about 10 replacement of SRS components. where is that in the manual?
Checking for used parts and maybe a whole parts car as a donor car. Or maybe using my current car as a parts car for a 99 manual T5 if i can find one reasonable.

That is in the SRS section.

I had everything deployed about 2 months ago in my 850 (low speed collision). I got all parts -- 2 airbags, both front belt with tensioners, clockspring, SRS Sensor/computer (under the center console), plus a few small parts, like turn signal, hood locking mechanism, glove box with lid, all for $ 200 at a place in Colchester, CT.

Windshield replacement was about $ 200 at Safelite Auto Glass (national chain).

Since your driver's airbag did not deploy, I would think that the rest of your system is good. Did the dealer's estimate include replacement of all? There is also a 30-odd page SRS section in the Service Manual, which you should read. My 98's V90 is the same as 95's 850. I doubt there are major changes for 99.

Replacement of that airbag should be very straight forward.

You can get a replacement dash pad and airbag from a salvage yard- there's enough of these cars there now that you should be able to find one. You should probably also replace the airbag control module, as well, as yours will have a code stored in it.

As for the "replace the airbag system every 10 years" nonsense, this is NOT unusual on European cars. VW, Mercedes, and BMW all used to say the same thing. This was from back in the day before it was understood just how long the chemicals used in the airbag systems would last, or whether certain parts might fail with age. Volvo specifically released a technical service bulletin several years ago that says that periodic replacement of airbag systems is no longer necessary because analysis of old parts showed little to no degradation over time, and that you should disregard the replacement advice.

Some words of caution when working with SRS components: Disconnect the battery before doing anything. I know that EVERY repair procedure says to do this, and you don't always have to... but it's as important here as it is when replacing a starter or alternator. DO THIS! Then, carry out the repairs in the following order: disconnect the airbag control module from its wiring harness. Remove the SRS components that you are planning to replace, in your case, the passenger side airbag and the control module. Before handling the replacement airbag unit, make sure to discharge any static electricity by standing firmly on the ground and touching a bare metal surface on the car. Wear safety glasses. Install the airbag unit, then the control module, then reconnect the control module. Before reconnecting the battery, put the key in the ignition and turn it to the on position. Make sure no one is in the car, then connect the battery. Wait a few minutes, then start the car. Make sure the SRS light turns off.

As for what airbag/ module to get, the 1998 S70 is unique (among S70 models) in that it has the older, 850- style pyrotechnic side airbags, which are actuated by a percussion cap mounted near the seat controls. in 1999, they went to electronic side airbags that are connected to, and activated by, the airbag module. As far as I know, the front airbag units themselves are the same. You'll need a module out of a 1999 or 2000 model, and a passenger airbag out of any S70. It's probably best to get the parts both out of a 1999 model car. If any airbags or seat belt pretensioners are deployed on the donor car, then the module will be bad. If you can't get a module, you should be able to get the original module reset by a Volvo specialist independent shop. Dealers won't do this on vehicles they didn't repair, and some independents won't either. If you can't find someone to do this, there's a company called BBA- reman (www.bba-reman.com) that can reset it for you- all you do is send it to them and they do the rest. Incidentally, this company is who I use for repairing ABS modules on my customers' cars- they're quick, inexpensive, and offer a lifetime guarantee.
