Ford has been sour in my experience (gas trucks)
I always heard about their product process control (it varies greatly) on the size parts they use. Stricter process control gives a better bell curve in reliability but that costs more money. To save on costs they cut down on this adhering to stricter product selection of samples. But really I think its all about preference. I've had bad experiences with ford (f-150's mainly/overheating problems with brakes/transmission/electrical going bad at 70k miles. seems 70k is a magic number to go get a new ford?) all the time and others have great ones (my boss had 960,000 miles on his ford titan f-150).
Compared to Dodge, dodge has a great diesel engine and decent hemi but their transmission is worse than ford I've heard (made in mexico).
GM has the allison transmission wihich is probably the best I've seen and used hands down for a truck. When my transmission needs 5.5 gallons of transmission fluid, temp gauge with transmission lock at 230 degrees; you know its not going to overheat haha.
And also if you do have a diesel ford 1999-2003; go get a new cruise control button because your car will catch on fire! (no joke)
Ford recall hits 4.5 million more vehicles on fire hazard - Oct. 13, 2009
I can't see how a car company can mess up like that + deny/didn't investigate until in 2008... Fix Or Recall Daily!
