so have i, my gas cap doesnt seal 100% all the time, big whoop. if the car shut down and refused to start until subaru cam and serviced it(tightened the cap and cleared the code), id be pissed.
Stop comparing automobiles to massive farm equipment. It isn't the same thing.
Here is a better analogy if you really want to compare automobiles to farm equipment.
Say you have a diesel engine that is putting 300+ psi into the fuel system since the injectors are mechanical and injects the diesel directly into the combustion chamber.
If the system detected a fuel leak would you rather have it shut down the vehicle or just let it keep running for a bit longer until the diesel catches fire and your vehicle burns to the ground?
