Active Bonnet issue?

Being very close to buying a late model Mk3 ( 25th ani / graphite etc) this active bonnet issue is a little worrying. Although to be honest I have phoned round a few MX5 specialist who have not had any issues reported. This could be because the models with Active Bonnet are still new-ish.

Anyhow a couple of questions, how confident would you be taking the MX5 on a track day knowing it has active bonnet, I spend a lot of time at circuits so dumpy fields, gravelly lanes with pot holes and on / off ferries etc. Am I worrying unnecessarily or should I consider a pre 2013 model.

Apparently you can’t de-activate the active bonnet.

Thanks

I’ve just picked up on this thread, and I have to say that I have never heard of a more ludicrous feature on a car.  If this was April 1st…

What makes this story worse still, is that it seems like the system (on Legoman’s car at any rate), was faulty and went off ‘half-cocked’ !

It is also very unfortunate that he is being given the run-around.  Obviously this feature deploying is quite unusual, as nobody seems to know what to do, and a number of questions regarding liability have been put forward by our learned membership.  Is it a production fault in the system (Mazda’s liability), or was it an accident (insurance company’s liability) ? 

I hate to be the prophet of doom here (sorry - must be the weather !), but I can see this situation being argued over for ages, leaving Legoman without a car, and possibly facing a four-figure bill for something that is not his fault.  Unless of course, someone actually puts there hand up to it !  Call me a cynic if you like, but…

The story related from Australia, and the way Mazda took care of everything is commendable, and I sincerely hope the same thing happens here.  Did I mention I was a cynic ? 

 

 

 

 

De-activating the bonnet sensor(s).  I wonder if Paul Roddison can throw some light on this matter?

I will ask him when I visit Tuesday October 24, Paul is stripping open a failed MK4 gearbox.

It should be a very interesting evening, start time 6.30 pm Roddison Motorsport Sheffield S9 1US.

I did a web search - mazda active bonnet - and found - Mazda MX5 Owner’s Manual: How The active Bonnet Works - (sorry I can’t do links) and it seems pretty worrying to me in that it lists situations where the system will activate, which include “light objects” and “small objects” even if they “don’t leave a mark”!  Also if the front/underneath comes in contact with a “sloping surface (garage ramp!), undulating road”.  It’s well worth reading!  So avoid low-flying insects, road shrapnel (grit and stones), speed bumps, potholes etc. at all costs!  Seems like it’s overly sensitive  over-kill (pardon the pun) to me.

PS:  Full information can be found in the FULL Owner’s Manual 2-54/55

I’m in full agreement with you there Countryboy.

I think it’s a daft idea anyway, and it wouldn’t surprise me if insurance companies soon cotton on to them - another excuse to increase premiums !  Or, is it perhaps stipulated in some small print in policies (that nobody ever reads !), that they will not pay out if the damn thing goes off on its own ?   After all, if you are not actually involved in an accident, but it deploys anyway, and you are out of warranty - what then ? 

the mk4 is looking less attractive every day…  what next ?

If you did remove/disable the actuator devices or unplugged the sensors, then hit and injured someone, could you be sued for causing injuries that were worse than they should have been?

Think your right bally3.

H’mm - Only Countryboys post makes sense, the general (above) assumption that the system will only deploy when the car hits a pedestrian is laughable, when a bump sensor activates the system. A car would need a sophisticated video system to give advance warning that a pedestrian was in line of sight BEFORE the sensors are made live - the cost being prohibitive.

Another sign of liberalism, triggered by over zealous ambulance chasers, liability clauses etc. Add technology gone mad, and you get closer to reality. Motto - avoid any car with it fitted. Also avoid driving such a car,if you made the mistake of buying one, the implications are plain enough. Resale values are beyond estimation, and you though Rust was a problem - - - - -.

If proximity to engine is a problem (Bonnet lid) then either fit an airbag to the lid, or a bull bar, and equip all cars with a dash cam (for insurance cover). Judging by a recent court case (track bicycle killing a pedestrian) which received nation wide publicity, no-one is safe from pedestrian idiocy any more. No media coverage gave any blame to said pedestrian, who presumably stepped in front of the cyclist, - where? we have no idea. Anyone with a track bike will stand on the pedals when the bike has a fixed wheel - given time and space for that to be effective. With or without brakes is immaterial. Any kid will tell you that. Damage will be confined to bike and rider, so a car driver has no chance.

I can only offer sympathy to the OP, Mazda has its regional view I’m afraid, and while OZ seems to have a sympathetic ear (and heart) the UK (NE) region differs, unless it becomes an international problem. No view from Stateside yet - I haven’t checked myself, but someone will no doubt.

Sandicliffe are a reputable dealer in this area, but they don’t have a body repair shop, so moving a car to such a shop is not unusual, and common practice. At the end of the day someone has to pay for the repairs, and it won’t be Sandicliffe. Having read Countryboy’s summation, then it would appear to be a manufacturing (design) fault, and as such surely Mazda’s liability?

As the OP is not a Club member, then I’m afraid the Club cannot help in what appears to be an isolated case, which is a shame, but advice is available to anyone with a problem - we pride ourselves on that. I suggest you approach Mazda and ask if they are willing to accept all, or some part of the expense, which is obviously not your fault. You need to write to head office here, not deal with phone calls, where staff are trained to reject liability, not help you to achieve it. Mazda staff will tell you the dealer is responsible for warranty claims, as I know well from personal experience. No dealer will offer help for what they regard as an accident, even if you did not cause it.

So Roger, and anyone with an ND - or a late Mk3.75, take heed, we now are sadly aware of the implications, and you are driving a cash problem. (and I thought I was - - --) For various reasons we need to know the outcome of this sad tale, so that all Club Owners can take this further. I’ve finished campaigning for Mazda Faults, so the balls in your court.Good luck all.

I’ve never heard of this feature. I have a Mk3.75, so presumably it’s fitted to my car. It sounds a good safety feature, and I trust such a devise would activate if I, as a regular cyclist, got hit. It appears the system deployed prematurely in this case, so should be covered by warranty I would have thought.

It’s very unlikely to be covered under warranty, as explained in an earlier post it’s in the manual that objects other than pedestrians can trigger it.

One time use feature so new bonnet and a pair of charges required.

All up costs, new lid, prime and spray, fit new charges, labour, reset system, at a guess two to three hundred quid. (Conservative estimate) Simple? 

Wait for next event - if you dare use the car again?

I’ve had a quote for a respray on a Mk2 bonnet, £240, that was some years ago. I think the bonnet alone (no paint) will just about come into your guess-timate.

Just guessing

 

Two to Three hundred quid for all that? you might need to add a nought.

I would be inclined to think that the cost of rectifying this situation would more likely be a couple of thousand !

Reading this thread got me thinking about my one-year-old Mazda3; does it have the lifter rams being mentioned above as yet another possible reason not to buy a car.

Two years ago on my first good look at an ND I’d immediately noticed the rams in the wings with the bright yellow connectors and warning labels,

ND Bonnet lifter ram

 

but I have not spent more than a few minutes looking under the bonnet of the Mazda3 so could not remember if it also had them.

Having just taken a look, no it does not, so, great relief.

More to the point, the big wide stiff cover over the Mazda3 engine is much further down below the bonnet, by about a couple of inches, and the engine itself is another couple of inches below the cover with filler and dipstick deeply recessed, and the heavy steel bonnet is much shorter and stiffer.  Compare this with the ND where the cam-chain housing must be only about an inch below the soft ali bonnet. 

So a pedestrian throwing himself at our new(ish) DD will not hit the engine, nor will he be punched by a ram if his aim is off centre.

I believe that the Fiat/Arbarth 124 versions have “active bonnet” systems too.  Correct me if I’m wrong.

If you want a nice looking sports car that meets pedestrian safety regulations then it’s a price you will have to pay, the insurance world will have it built into their risk model. As this is the first recorded (on here) instance in the two years the car has been on the road then I’d suggest it’s likely to be a rare event.

All those getting outraged about progress maybe it’s time to buy a Bauxhall Astra…
