What 2003 Ford Thunderbird owners say
Engine & cooling
I've owned my 2003 Thunderbird since it was new. It now has 65000 miles and is driven only 2000 miles a year, over the last 5 years. During this period, I have had all 8 coils replaced, one at a time. The first time was within the first 1000 miles. Generally it occurs while driving in traffic, being on the freeway or on local streets. The engine starts to misfire and not function. After the 3rd or so incident, I was informed that Ford recognized the problem and would honor the repair. The only problem with this, knowing of the problem, they refused to replace all at the same time. In other words, they would only replace when the coil malfunctioned, this now has occurred 8 times. Now my motor has failed and needs to be replaced. My understanding is that when the coil malfunctions the corresponding cylinder also is not functioning properly. …
Driving on a 1,850 mile trip. Car engine repeatedly shut off on light acceleration from complete stop. Motor light and wrench light illuminated. Put can in neutral and re-started. Wrench light de-illuminated, motor light stayed on. Acceleration could barely be attained to keep engine running up to 45 MPH. After that speed, can ran somewhat normally,. Entering an expressway at very low speed with minimum acceleration became the only way to continue the trip. Very dangerous. Went to a Ford dealer on route. Because I was from out of state he agreed to work me in for service that day. However, after I described the problem, service writer refused my request to put car on their diagnostic machine. He agreed to change the fuel filter only. Dealer would do no other work. Told me I would have to leave it several days. I tried two tanks of fuel with a stoddard solvent injector cleaner. At home. …
Transmission & drivetrain
Dt: while driving at 55-60 MPH the engine started to bog down and slowly died. Had been to dealer numerous times concerning this problem and a transmission. Vehicle had been checked diagnosticians, and was unable to find anything wrong. Dealer had never indicated what was wrong. No repairs were made other than a rebuild of the transmission when first purchased. Problem with the engine dying was intermittent. No repairs were made because they were unable to determine the cause of the problem.
The vehicles rearend (differential) develops a howling noise, noticable at 40+ MPH. This same problem has occurred twice before. The dealership has replaced the rearend on two previous occassions. The noise is starting to occur again, if replaced this would be the fourth rearend.
