Round 3...
Dear Mr Carter,
Thank you for your letter of 30th July. Please understand that the only reason we as owners chose to contact the DVSA directly is concern for the safety of other road users, as the initial contact with Maserati UK and Maserati Italy had led nowhere.
It's odd that only 5 cases have been reported to you as we are aware of at least 7 cases having been filed with the DVSA covering 10 wishbones (front and rear) and currently 7 more cases covering 9 more wishbones (front and rear) are to be filed soon. With more failures turning up each month I'd expect the number of cases being filed with the DVSA to continue to rise. This is quite a significant number for a niche set of vehicles which have only just started to get examined by a small number of enthusiasts.
Regarding the fact that only mine has currently been recorded as a fully failed wishbone, (though we know of one other) I'm sure you appreciate that the next stage after cracking on the wishbone is separation from the vehicle in question. The others that have only displayed cracking so far have not had a full failure because WE notified the owners and managed to find them in time and get them removed from the cars in question.
The UK has a wealth of specialist engineering experience who could examine these parts in a couple days and provide an independent view on the cause behind the failures without any vested interest. The DVSA could then alert owners if it feels there is an issue and then work with the manufacturer towards a solution. The fact the DVSA relies on the manufacturer of the parts to drag its heels in deciding whether it is their manufacturing/design at fault or the end user is shocking. History is littered with examples of car manufactures doing absolutely anything to avoid admitting liability, and therefore trusting them with any initial analysis work which can result in the destruction of the evidence is alarming.
Whilst the lengthy investigations take place as to the source of the fault, there were (and still are) cars driving around on our roads on the brink of an accident with the owners unaware. Considering the magnitude of the outcome of such a failure I personally find over 6 months of investigation worrisome, especially as the analysis of such material faults and manufacturing processes are so well known.
I feel it's only right to make sure our feelings are recorded should the worst happen. Again this is not about finger pointing, laying blame at anybodies doors, expecting compensation or anything of the like. Our concern is getting fellow owners notified that they should get their cars checked as soon as possible. We as a group of enthusiasts are unable to tell all owners to get their cars checked as we simply don't know who they are, the DVSA and Maserati have a far better chance of doing so.
Of significant interest is the new wishbones that are now available from Maserati that are of a completely different design and feature extra material around the failure points. We've heard rumors from many sources about “redesigned components” for a while, however this is the first time we've seen them. For Maserati to go to this much effort re-engineering parts for cars that are no longer sold, whilst telling the owners of the cars that there is no issue raises very serious questions. A cynic would suggest that they were well aware of this impending issue and tried to profit from it rather than concern themselves with the consequences of failure. For your interest I've included pictures of a new rear upper wishbone side by side with the old design so you can see for yourself.
Hopefully can be resolved quickly before somebody is seriously injured, or worse.
