2002 Ford Thunderbird Problems

What owners report

Owners of the 2002 Thunderbird most often describe misfires and sudden loss of power traced to ignition coil-on-plug and spark plug failures, frequently accompanied by oil contamination from valve cover gasket leaks. Many complaints also focus on the airbag warning light coming on and on the alarm that the same coil repair was covered on later model years but not this one. Reports span very low mileage examples to cars past 70,000 miles, with the coil-related complaints clustered between roughly 10,000 and 60,000 miles.

   Ignition coil / spark plug misfire and stalling

   • 36 complaints (39%)
   • median 43,468 mi at 9.7 yrs old (28 state mileage)
   • owner-quoted repair $1,500 (median of 15 quotes)
   • filed 2007–2017

   Owners describe the engine running rough, misfiring, flashing check engine lights, and sudden loss of power or stalling while driving. Several say a dealer or shop replaced one or more coil-on-plug units and spark plugs, sometimes repeatedly, and that the problem returned after repair. A number of complaints note that later model years received free coil replacement while this model year did not. Reported from about 4,500 to 76,000 miles, with many reports between 20,000 and 60,000 miles, often during acceleration or at highway speeds.

   What to check: On a test drive, feel for hesitation or roughness under acceleration and watch for a flashing check engine light; ask for service records showing whether coils, plugs and valve cover gaskets were replaced. A pre-purchase scan for misfire codes is worthwhile.

   2 excerpts from owner complaints in NHTSA records

   “I have a 2002 Ford t-bird with approx 60k milies, original owner. I've had three coils replaced at my expense. On 25 aug 2011, while diving in the fast lane (three lanes) at approx 60 MPH, the engine suddenly quit, causing a loss of brakes and steering. I was fortunate to be able to muscle the car into the break down lane and stop. The car started without issue after putting it in park.”

   NHTSA complaint #10421583, filed 2011-08, 60,000 miles

   “I've seen numerous complaints for this same issue and I've done a lot of research on it. My 2002 Ford Thunderbird began having this problem at 43,700 miles. I did not know what the issue was and it was intermittent. Within the past month (september, 2011), I have personally replaced all eight plugs, boots and coils. While doing this I found three plugs that were oil fouled. After completing this repair the car continues to drive rough. …”

   Vehicle speed control

   Unexpected acceleration or surging

   • 13 complaints (14%)
   • median 29,000 mi at 7.0 yrs old (12 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2003–2016

   Owners describe the car surging forward or continuing to accelerate with the brake applied, and in some cases trouble getting cruise control to engage or hold speed. Dealers in several complaints could not reproduce the condition, while others traced related behavior to an idle control or brake pedal switch. Some complaints link rough running coils to abnormal acceleration. Mostly reported between about 4,500 and 50,000 miles, often at low speed, in parking maneuvers or when pulling away from a stop.

   What to check: During a test drive, check that the throttle returns cleanly, that cruise control engages and cancels, and ask whether the idle control valve or brake pedal switch has been replaced.

   “This complaint is reguarding a 2002 Ford Thunderbird. I am the origianl owner, and have had the car in a Ford repair shop 4 times for the same problem. The engine throttle sticks, usually when the the brakes are applied. The last incident resulted in the car running through the kitchen of my house. Ford can not find any reason for this reoccuring problem”

   NHTSA complaint #10128841, filed 2005-07, 13,217 miles

   “I went to park the car and the car went racing into the spot and it was difficult to make it stop. I through the car into park and even then I was sure it was going to stop. If I didn't have an empty parking lot I don't think it would have been possible there would have been an accident. Then I had to drive the car home which I didn't want to do, because this was very frightening. …”

   Engine cooling

   Oil leaking onto plugs and coils (valve cover gasket)

   • 12 complaints (13%)
   • median 39,436 mi at 8.2 yrs old (11 state mileage)
   • filed 2008–2017

   Complaints describe oil found in the spark plug wells, coating plugs and coil packs, with dealers attributing it to valve cover or manifold gasket leaks. Some owners report smoke from the engine bay and gasket replacement, while others say the misfire continued after the repair. A few describe oil and fuel mixing and engine work that did not resolve the problem. Mostly reported between about 30,000 and 76,000 miles, and in some cases as a cause identified only after misfire symptoms appeared.

   1 related service bulletin

   What to check: Ask whether the valve cover gaskets have been replaced, and have a mechanic pull a coil or two to look for oil in the plug wells before buying.

   “The contact owns a 2002 Ford Thunderbird. The contact stated the oil and gas are mixing in the valve. The rings were replaced but the problem persisted. The contact called the Ford manufacturer and was told there is no recall or warranty on this problem and that they would have to repair the problem themselves. The failure mileage was 39,436.”

   NHTSA complaint #10305193, filed 2010-02, 39,436 miles

   “The contact owns a 2002 Ford Thunderbird. While driving 5 MPH, the service engine light illuminated after the vehicle had been serviced for its 30,000 mile routine maintenance. The dealer stated that the manifold gasket leaked oil onto the coils and spark plugs. All of the failures needed to be repaired. The failure mileage was 76,000 and current mileage was 76,050.”

   Engine

   Sudden engine shutdown while driving

   • 13 complaints (14%)
   • median 37,000 mi at 9.9 yrs old (13 state mileage)
   • filed 2003–2023

   Owners report the engine quitting without warning, sometimes during a turn or at speed, leaving reduced steering and braking effort until the car is restarted. Several say the vehicle restarted normally afterward and that dealers could not duplicate the problem. Some link the shutdowns to coil, plug or fuel pump faults found later. Reported from near-new mileage up to about 75,000 miles, with several reports under 30,000 miles and instances at low speed as well as highway speed.

   What to check: Ask whether any stalling episodes were diagnosed, and have the ignition system and fuel pump circuit checked; a history of cleared misfire codes is worth asking about.

   “Twice my 2002 Thunderbird's engine has stopped while I am driving it. Both times, it occurred as I was making a left turn in front of oncoming traffic in a 55 MPH zone. When it quit, I was unable to steer or control the vehicle in any way. I had to put it in park and restart it before I could leave the oncoming lane. Ford has an unpublished oasis special service message 16581 which states: 2000-2002 lincoln ls & 2002 Thunderbird - intermittent engine quit on decel/stops/turns. …”

   NHTSA complaint #10014291, filed 2003-04, 10 miles

   “Engine failure. While driving approx 40 MPH. Slowed to stop for an animal in the road and engine failed. I shifted to neutral and restarted w/o problem. Had this occured in a busy intersection, it could have resulted in serious injury and/or death. Please investigate and notify Ford. This is not the first complaing you hav recieved regarding this problem.”

   Air bags

   Airbag warning light and clock spring

   • 11 complaints (12%)
   • median 55,861 mi at 9.7 yrs old (9 state mileage, few)
   • 3 mention a crash, fire or injury
   • filed 2002–2019

   Complaints describe the airbag indicator lighting up and staying on, with dealers diagnosing a faulty clock spring in the steering column. Several owners report that replacement parts were unavailable or that repairs were quoted at their own expense. One complaint describes a rollover in which the airbag reportedly did not deploy sufficiently. Reported from very low mileage examples up to about 69,000 miles, with many appearing between 50,000 and 60,000 miles.

   What to check: Confirm the airbag light goes out after the bulb check on startup, and ask whether the clock spring or airbag module has been replaced and whether parts were available.

   “The most recent problem started in june 2009 when the airbag indicator light came on for no reason and wouldn't go off (is it working or not? Safety issue?) then within a matter of weeks everything on the steering column controls quit working or went berserk. The cruise controls suddenly went haywire accelerating when any button was pushed now they don't work at all (safety issue). A car pulled out in front of me, I slammed on the brakes and laid on the horn and nothing!!! …”

   NHTSA complaint #10279466, filed 2009-08, 26,000 miles

   “My daughter was in a rollover accident on 09 -06 -2016 in a 2002 Ford Thunderbird convertible. The air bag did not sufficiently deploy & she was severely injured as a result. She was on interstate 95n near manning, sc when a semi truck did not see her & came into her lane grazing the car. She had to go off the road or the truck would have crushed her. The Thunderbird rolled over & she was severely injured.”

Buying note. Have any 2002 Thunderbird inspected for ignition coil, plug and valve cover gasket condition before purchase, since those repairs recur and are not cheap. Also verify the airbag warning light behavior and ask for records of past stalling or surging diagnoses, as several complaints describe symptoms dealers could not reproduce.
