1 Engine problem

Failure Date: 03/27/2009

All technical service bulletin stating that vehicles built before 12/19/04 have this problem. A engine cylinder with no compression. Ford is aware but does not want to do anything about it. If fact they want the damaged part return and it's not for a core exchange since the new part has to be brand new replacement. Must be for evidence of faulty part.

2 Engine problem

Failure Date: 11/09/2007

On cold start, there is a "ticking" sound. Took it to mechanic and he gave me a technical service bulletin article #03-25-6, dated 12/22/03, regarding Ford, Lincoln and Mercury engines built before 9/17/2003. Emailed Ford motor company to find out what could be done to rectify the situation as it is a known defect of the car although it is not a safety issue. All they could tell me is there is no recall and take it to an authorized dealer to have it diagnosed and repaired if need.

3 Engine problem

Failure Date: 03/23/2006

While sitting at the traffic intersection awaiting the light to turn green. I heard a loud pop from under hood and all of sudden the car began to run like crap. I pulled over to check under the car to see if something had fallen off, but I found nothing. I then checked under the hood to find out my spark blew out my passenger side cylinder head. I took it to the Ford dealership for repairs, but my extended warranty would not pay for the repair because they do not cover spark plug damages. This left with a $4,463 repair cost to fix my car that I only owned for three months. While doing research on the internet and asking questions in mechanic shops, it has been apparent that Ford engines have defective cylinder heads and recall needs to be issues in regard to this matter. There are many victims affected by this issue and Ford has done nothing about this problem. I drive a 2003 Ford Mustang cobra. I have not repaired my car yet because I'm still hoping for $4000 to fall from the sky.

4 Engine problem

Failure Date: 11/28/2003

Vehicle's engine has died several times when decelerating. When this happens, the power steering and brakes are obviously lost as well. The first time it happened I nearly sailed into a busy intersection. The second time it occured I was coming off of an freeway exit and almost rear-ended the person at the light in front of me. My understanding, from talking with various people on the internet is that this problem is widespread among 2003 Mustang cobra owners. Something needs to be done to correct this situation before someone gets injured or killed.
