I must admit I was impressed with my Pal's Fiesta (he is less impressed with the TPMS).
I know most of these work OK but I would put the question - what is an acceptable level of reliability for these systems? Let's, for the sake of argument, say that 90% of these systems work. I regard that as unacceptable. Try googling clutch failure on nearly new Hondas and you will get virtually no responses. Why, because the clutches are fit for purpose. Google Deflation Warning System or TPMS and you find a tsunami of negative stories and a whole industry developing around methods of defeating or disabling these systems.
They are unreliable period and you have to ask why a legal requirement was put in place before a robust technology was available. We got on without these things until 2014 for heavens sake. Why do we have to put up with them now and the inability of the manufacturers to come up with solutions when they fail?
