2004 Ford Mustang GT problems

Front brakes drag or freeeze up causing extreme heat or actually stop vehicle. Car has 18,000 miles. Front calipers have been rebuilt twice. First failure at ten years,then failed after apx 3 years. The problem is the phenolic pistons swell after time or due to lose of lubrication. They change dimension and stick in the caliper. This is the 3 rd vehicle with the same probem. 81 ford f150, 98 ford f150 front disk brakes. Both after the vehicle had been on the road about 10 years. When pistons have been replaced with metal pistons I have had no more issues with the front brakes. The mustang has no metal piston available and had to be rebuilt with after market phenolic pistons. They failed again probably because of lack of lubrication of boot and piston. Somehow I feel this is a chronic failure and happens a lot without anybody being aware that time and or heat affect the phenolic piston and cause brake failure.this failure is strictly vehicle related and not due to any external causes except time, heat, or lubrication. I feel the weight of the non metallic piston doesn't compensate for the cost of the brake failure that it causes. I've been told by ford that the phenolic pistons were selected to save weight.

I started the car up to drive out of the grocery parking lot and the car was sputtering. When I pulled onto the main highway it sputtered and completely stopped running. I coasted to the side of the road where it failed to restart.

On multiple occasions the number five spark plug keeps blowing out of the head. The car has motorcraft spark plugs and are torqued to the factory specifications. While looking into the problem online I found out that im not the only person having this problem. The crazy thing is that its is only happening with the number five plug.

The top of the clutch pedal assembly when depressed and released rubs the wiring harness to the brake switch, neutral safety switch and others shorting out the brake lights and making the cruise control inoperable. It works for a while but then it blows the fuse again and someone has to stop me and tell me my brake lights don't work. The dealer has replaced one of the wires for the brake switch which is in that same wiring harness and says the problem is fixed but sooner or later it will rub the rest of the wires bare too. I have also replaced the brake switch a couple times because when it shorts out it melts it if the fuse doesn't blow right away. I am afraid one time someone will rear end me or I will get a ticket.

I own a 2004 mustang with a 4.6 dohc engine. Last night the spark plug blew out of the head. The head now needs to be repaired by using a helicoil or something similar. This is a huge problem with the ford modular engines, caused by poor design. At least 75% of the people I know who own fords with modular engines have had this problem.
