A lot has to do with brand image and people's mentality. Which truck brand gets bashed more than the others? So, it makes sense when there is a recall of any kind, people will jump all over it. And yet, like Rangerx2 pointed out, other makes will have some really serious issues that people will turn a blind eye to. The Ranger transmission issue, from what I've been told, was not Ford's fault but the part manufacturer's fault. Ford, to their credit, found the issue quick and jumped on it. It shut down the production line for a bit and is ticking people off but better now with a few vehicles than with thousands out on the road and the potential deaths that could have resulted from it. Also, the PR hit will be a lot less because of it.
How many remember the Firestone/Ford debacle and all the bad press that came from it for both brands? If memory serves, Ford chose poorly on the tire for the size of the vehicle and the psi they wanted to run them at (not enough of a safety margin to protect the ignorant/lazy). People, being lazy or ignorant, never checked their tire pressures and tires started blowing out. Since there wasn't enough of a margin to protect the stupid, lawsuits happened. I think Ford took the majority of the hit but Firestone wasn't a happy camper either. Firestone is still a good tire manufacturer and Ford still tends to make good vehicles. But Explorers are now called Exploders by some and some people refuse to buy Firestone.
