As a relatively new owner and member of this community, I am a bit puzzled by the tone of this thread.
1) Our cars are up to 16 years old! A suspension lever and bush cannot be expected to last an eternity. I had a look at my service history, and the parts in question where routinely checked and changed as needed of the 13 years and 49000 miles my car has been on the road. To be precise, on 5 occasions but never the same part.
2) We have some of the worst roads in Europe in the UK. Potholes and speed bumps are countless, and whatever care we are applying to our driving, we do get the odd knock regularly.
3) Our cars are sensitive beasts, we laugh/smile about their character regularly in this forum, and this is why we like them, there is a lot of talk about performance, cornering, speed, this all comes at a cost, especially if a car is not driven for longer periods of time.
4) Most of us bought used cars, however good the service history is, there is still the element of unknown as to the care given to the car by previous hands.
So whilst I understand the aggravation caused to cars and drivers during the mentioned cases, I don't understand the direction of this discussion thread. We wanted to know whether there was some form of defect. Maserati's position is clear: the components are serviceable items and a routine check is an integral part of the regular servicing schedule, this has always been the case.
Where does that live us? If the servicing has been done properly, and we experience an issue, than surely the culprit is at worst the party doing the service. By the way, this is the law I think. At worst, this action will have reminded less careful specialists of the procedure to follow, bonus for everyone.
Looking at the content in other threads, there seems to be a high disparity in the quality of the specialists or even main dealers, and for this there is a solution: walk away from your current provider if he failed to spot the issue and find someone better, making sure you let everyone know. For the DIYers among us, it may be worth going to see a specialist to have a second pairs of eyes perform a check.
I know I am not going to be popular on this one, but I felt I had to say something... And I don't work for Maserati
