The IQ is quite a new and "groundbreaking" design that is quite a "bold step" taken by Toyota to create something different and very appealing to a "specific market segment" of todays motoring buyers however this challenge in itself does come with some risk if not approached very carefully and carried out in a specific manner. Perhaps some of the problems in my view with the Design of the IQ car is as follows: Very lightweight materials have been used that can be more suspetable to wear / breakage and possibly early failure. Small and very compact design of some parts that break some of the standard traditional more proven engineering design trends in order to reduce size of many parts. Cheaper materials are perhaps sometimes used to reduce manufacturing costs to a minimum. All new design concepts will always be at a slightly higher risk of problems in a mass produced manufacturing environment. Possibly a lack of enough "testing to failure" after the new design has been created, in order to reveal and show up any possible weakness up front, and then implement further design modifications and changes to create quite close to zero defect that matches more traditional / proven design of some parts and thus make the IQ comparable to other car reliability standards that we have come to expect from a modern motor car. The above issues could (if it is the case ?) lead to the customers (that's us) becoming the test bed for design changes and improvements over time, and suffering some problems that could have been avoided if a different and much greater focussed testing to failure approach had been taken by Toyota. As Toyota now offer a 5 year warranty as a selling point on new IQ's we (as end customers) are "lead to believe" that reliability will be very good, this is not always the case. Some manufacturers are now offering 7 year warranties ! Toyota have perhaps been more "up front" regarding recalls and this is of course a "double edged sword" that can put some people off Toyota, however I believe that "up front" honesty will win over the customer rather than hiding the problem, this has been proven to be the case as I understand that Toyota sales have not suffered because of it. The above is my view at the moment after owning a second hand IQ now for 5 months and reading this forum almost every day, plus some time taken to research on the internet the IQ design and its new concepts. All comments regarding my above views are welcomed. Positive Regards, Bob.
