It would be a good move if car manufacturers provided a technical advice service but would have to balance it against dealer income. Also there would be repeat complainers that are never satisfied.
This sounds a bit like TG on this forum - he seems to have in-depth knowledge of a lot of things does TG stand for Technical Guy
Oh thanks...
The automotive industry could take a leaf out of the software industry support methods; after many years of third party forums providing the best guidance and fault resolution the developers have started to properly run their own community forums, a million engaged users will beat 100 support staff for depth of knowledge and resourcefulness every time. In any sector where personal and 3rd party safety may be affected I guess for legal reasons you can't endorse amateur advice so (except for Tesla) official automotive forums won't appear.
I joined this forum to complain about my failed rear wheel bearing. Have since complained about Nationwide (now Halfords Autocentres) inability to fit an exhaust correctly, and after using Ford/VW/JLR touchscreens feel justified in complaining about Honda infotainment faults even though I don't possess one.
Upbringing and curiosity means I'm of the mindset that you can fix anything*, and there's always another tool you can buy. My CEng IMechE father used to race an MG-TC, and he was in Mobil Special Products division which meant getting to poke around these two Patrick Head (Williams) designs as a school holiday perk.
