Is this actually true?Some of the modern cars, if anything electronics go wrong , local mechanic can’t deal with as they need dealership level diagnostics.
I don’t know how easy it is to get those diagnostic tools or how much of a cost barrier it is.
But my local tyre pro doesn’t have the computer to be able to calibrate my cars wheel alignment. Apparently there isn’t one for miles around.
Gov can introduce right to repair, OEM can still find loopholes ie putting up cost of specialist tools so that only their dealership or very large workshop will have such things.
It is definitely a worrying trend. Probably also why insurance premiums go up so much all of the sudden as a general trend.
I’m pretty sure you can get suitable diagnostic equipment for pretty much any vehicle, even Tesla, the so-called unrepairable car.
End users can even pay to use Tesla’s in house software as an end user and it isn’t particularly expensive. 24 hours access is only a few £.
Your local tyre shop may not have the latest software on their wheel alignment machines or they may have invested in machines that don’t regularly get updated by their manufacturer which is why they can’t do your car. The sample of one doesn’t necessarily identify a particular problem.
