1 Manifold/header/muffler/tail Pipe problem

Failure Date: 07/17/2014

The car was built with a plastic intake manifold. The manifold began leaking at the thermostat housing and then the heater hose connection on the intake manifold suddenly broke. I now have to have the entire intake manifold replaced because of poor design and material selection. Ford knew of the problem but refuses to address the issue and hopes it will just go away. They should reimburse the owners of the vehichles for repairs that were due to poor design and materials used to make this part.

Failure Date: 07/23/2006

(7/23/06) 1999 Ford Mustang gt, 4. 6l blew spark plug for the third time now. The first time was back in 2005 while driving on the 15 freeway heading south at about 8:00 pm. Stop to get gas and upon starting the vehicle to continue my way home it made loud pop and then continued to pop, pop, pop. At first I thought I had an exhaust manifold problem, but upon the repair shop inspection of the vehicle they noted that the number one spark plug had blew out of the piston. They repaired it for about $ the second time was about 6 months ago when the number two spark plug (all this being on the drivers side) blew out. No damage to the threads and a new set of spark plugs were put into the vehicle all around. Then on Sunday evening, July 23rd 2006, the same number 2 spark plug blew out again; this time taking all the threads with it. I had to have the car towed to my place of residence and now I am in the process of finding a repair shop to re-thread the piston. I am sure they will have to get a new coil as well; since it broke off at the place of were it is bolted to the head. I called Ford motor company on Tuesday, July 25th 2006 and spoke to customer service rep. And basically was given a not our problem attitude. This is appalling that such a large company as Ford will not acknowledge the problem and fix it! I am a single mother and can not afford to have my car fixed at over $3000. 00! I am not happy with Ford and will not buy from them again. I was a huge Ford fan; when anyone would try to discredit them I would back them all the way! not any more they don't back their customers. I guess Ford motor company has no loyalty to their customers what so ever! so I shall no longer be loyal to them. I will be buying a chevy or other vehicle that has no association with the Ford name, as soon as this is fixed. She's being traded in ASAP!.

My car is losing coolant through a crack in the plastic intake manifold. Ford will not repair it under any warranty. It is a design flaw that Ford should take care of! also my car surges in rpms when first starting and shifting into drive,,,very dangerous!!!!!.

9 Manifold/header/muffler/tail Pipe problem

Failure Date: 12/18/2003

I have a cracked intake manifold on my 1999 Ford Mustang gt with a 4. 6 l engine. It have gained knowledge that this has been a common defect on this engine since the 1996 model year on almost every Ford motors vehicle with this engine setup. Ford has not issued a recall on this known defective part and does not admit to this problem in their vehicles. Upon contacting their customer service, they will not offer any assistance on the repair that will cost their individual customers hundreds of dollars to repair and replace. I find this unacceptable from a company that markets their quality to the american public while not fessing up to a manufacturers defect that has been known for at least seven years. * cb.
