As cars are more electronic than ever, the vast majority of problems that news owners typically experience are software related. No idea how FCA plans to address these welding issues, as I don't feel like spot fixes are really a solution.
They wont be spot welding, that's a given. And to be honest if I was a new JL owner I'd be asking for a replacement model instead. $50k for a new JLU and they want to put a band aid on something this serious.
We'll need to wait and see just how far reaching this issue is, before we can determine the best route for FCA to take. If it only affects the estimated 4% of models, then they can easily get away with just doing some spot repairs.
