While I agree the government has made vehicle development annoyingly complicated, FCA's parts aren't shitty because of that. Chrysler has been cheaping out on parts when they started circling the drain back in the late 2000's and Fiat joining the mix only added more shit to an existing pile of shit.To a certain degree we all have our Federal government to blame for these kinds of headaches in our lives. The more government dictates fuel economy the more car parts are made to be as light (flimsy) as possible to keep the weight down.
I can remember when the rear seat backs of my SUVs were steel to make for a truly useful cargo area when the seats folded down. Now, a Suburban is hardly useful for the way it was originally designed.
Stop for a minute to think about all the ways our lives are negatively affected by government regulations.
