Example complaints
Electrical system: “Since I bought this car I have had dozens of stalling incedents both while driving and at stop lights.I have had it at Ford dealerships and they tell me they can't find the problem. Sawgrass Ford in florida told me that they don't know what the problem is I'm having and the gave me an estimate of $1040.00 to fix the car. I took it to independent auto repair shops and they don't know why it stalls all the time. I read an article from california that names the tfi module as the probable cause. Ford has known of this problem with cars made from 1983 to 1995. …”
