About 5 years ago I had 2 new Fords fail within weeks of buying. Ive owned lots of cars and many of them Fords....but one of those failures was the CVT tranny blowing on the one I had given to my Dad (he ONLY drives Fords)...with his wife in the car, on a 100 degree day on a shadeless stretch of road north of Winnemucca...... I was more that a little pissed off. Sure they fixed it, but that does nothing for my worries about an 85 year old couple baking in the sun. The other one was my wifes Focus which died on the freeway. I managed to roll it off a ramp and establish that no fuel was flowing....and then traced that to the emergency shutoff switch which was improperly installed.
First situation was caused by specifying an inadequate transmission. Lets say engineers and managers own that one.
Second was clearly the fault of whoever did assembly.
I expressed my displeasure to everyone available, from the dealer on up ( I dont know the email address of the assembly person

)
I have bought other Fords since, of various vintage and design. None have failed. Ive also bought a Mercedes which had some annoying flaws, which were correctable at a price $$. A BMW Z3 that required me to spend some forum time correcting. GMC, Chevy..
Aint none of them perfect. I do some level of hassle vs value analysis regularly...some things are worth dealing with, some are not.
So far everything Ive done to both my 449/511s and 250/310s has fallen into the 'worth dealing with' category.
Your accounting my vary depending on actual pain and perception of value.
