This puts me off buying a new car.

I’d like to see vehicle manufacturers, for the purpose of regular retail owners, extend the warranty of a vehicle if it spends more time in the workshop than the allotted time set out in the repair manual.

If remove and replace engine is, for example, 10hrs, then the car should be in the shop for no more than, say, two to three days. If it sits there for days > weeks > months waiting for parts the new car warranty should be extended by the same amount of time.

My guess is that’d go a long way to fixing the spare parts waiting times.

What are the possible reasons for such long waiting times on spares? It can’t be freight delays; it can’t be that the part isn’t available.
