I want to add my name to the ranks of Ford F150 owners who had the nightmarish experience of simply needing spark plugs changed. Unaware that there was a problem with this sparkplug design, I asked my mechanic to do a simple tune up. Two sparkplugs broke and he is still researching how to proceed without incurring the most expense. Tells us about inexpensive recall items, is it because this is expensive that they have not issued recall on this design flaw?

2004 Ford F150 bought new. Rear window (over back seat) motor/regulator broken over a year ago, fortunately with window closed. Ford says that it will cost close to $500 to replace motor. Yesterday, 5/21/2011, right rear window regulator broke. Window will not stay up. From what I see, this has happened to hundreds if not thousands of people yet Ford will not address it as a recall item. Can't the NHTSA put pressure on Ford or the government to force Ford to fix these when they break" it is definitely a safety issue! Ford bought defective window motors/regulators and are leaving their customers to contend with them alone. Why can't they admit to a problem"

2004 Ford F150 supercrew. For the 5th time one of the windows has dropped into the door due to the regulator malfunctioning. The first 3 times were covered by the extended warranty I purchased. However, this will be the second one I will have to pay for. Each time, all Ford does is replace the regulator and tell me I must have gotten a bad one. This is 5 windows in 5 years.

I have a 2004 Ford F150. I have had to repair all four of the power windows. The windows would just slide down into the door frame. All four times the Ford dealer had to replace the power window regulator. Now I see from the internet I am not alone. Could you please look into this issue and maybe make Ford recall the truck and fix this issue and reimburse people like me who had to pay to fix the windows. I am sure this will happen again.

Ford F150 window regulator failure.

- Lake Placid, FL, USA

Ford F150 crew cab. At 45,000 miles the F/drivers side window regulator failed. Replaced under warranty. At 76,000 miles F/passenger side window regulator failed. Replaced out of warranty. At 95,000 miles R/passenger window regulator has failed. Has not been to the dealer for the latest failure. I do not know what the cost will be or when the R/ drivers side will fail. Neither of the rear windows have been used more than 50 times during my ownership of the vehicle, which I bought new. It seems to me that from what I have read from others and my own problems that there is a defect that Ford should be responsible for. It appears they are unwilling to face up to their responsibility.

Two broken window regulators within approximately two weeks. I attempted to roll down windows and I heard a noise and window just dropped down into the door. No broken glass, but very uncomfortable with young kids and you're away from home in cold weather.

I have a 2004 Ford F150 truck with only about 60,000 miles on it. My passenger window just slid down as I was driving! did not push any buttons! of course I then tried to roll the window up but it wouldn't work. Now my window is left wide open while I have to wait to get it fixed! I had it checked out and its the regulator that needs replaced. I've already had to replace my rear passenger side regulator but I didn't realize then that it was a defect in the part! I'm still trying to get it fixed.

We purchased our 2004 F150 in Sept/Oct of '04. Shortly after our mileage warranty expired (36,000) miles our window assembly regulator broke and we had to pay over $400 for it to be repaired. A short time later our second window assembly regulator broke and they only asked us to pay 20% of the repair bill equaling $55. 9 months later our third window regulator assembly broke. When these windows regulators break it is during random times and while driving. No one is rolling the windows down they just all of a sudden fall down. We were driving on the freeway at 65 mph and I had my 12 month old daughter sitting next to the window that broke and she had her hand on the door next to the window. She only had a small red mark on her finger however she was crying hysterically because it scared her. While looking online I have found thousands of other complaints about the window regulators breaking on these trucks. When we called to get the truck repaired the had the part in stock and within us making a decision of when to bring the truck in an hour and a half later the part was already used. The repair tech said that it is their most common problem. I feel that this is a major safety issue. If my daughters hand had been any closer it would have been severely pinched. What if the window were to shatter while going down on the freeway at those speeds? Ford is unwilling to repair our fourth window and we fear it is just a matter of time before it breaks as well.

My drivers side window just fell open while driving and would not go back up. After investigating the power window unit had broken. 7 days later the same thing happened to the rear passenger window. The dealer told me this is common and is a defect but Ford refuses to recall them. The dealer said it will most likely happen to your other 2 windows as well! $400 each to repair.

My 2004 F-150 electric windows keep failing. They fall into the door while I am driving and it happens with no notice and at highway speeds. When it happens it is quite distracting because of sudden there is a loud noise and a huge force of air coming into the cabin. When it first happened I thought someone had fired a weapon at my truck. The first time it happened the dealer fixed the problem under warranty but would not fix the other windows even though they admitted the problem was common with my type of vehicle. It happened again just after warranty expired and the dealer split the cost with me. The third time it happened I was on my own. It is a several hundred dollar repair. The problem appears to be a simple piece of plastic with a pulley that allows a cable to wind around a motor shaft. Although the cause is simple, the repair is not and the entire door must be taken apart. The biggest problem is that the failure will scare the driver and significantly take your mind off the road. If a child is sitting next to the window, the event could even have more several consequences. Ford apparently knows of the problem based of Ford mechanic comments about the issue being common to the 2004 F-150 and the number of repair kits they go through. Below the date is the most recent occurrence.

I have a Ford regency F-150 with a factory 6 inch lift done by regency. When the lift was done the steering linkage is in contact with the brake line so when the steering wheel is turned a hole was worn in the brake line causing a loss of brake pressure. I talked to regency and rick said it was the second he had heard of. Mine is being fixed now but anyone else who owns one of these vehicles is at risk of an accident. I am reporting this in the hopes no one is hurt unnecessarily.
