“My 2004 Lincoln LS has never been in an accident. Approximately 60 days ago my check engine light came on after getting bad gas. Was able to reset by removing the battery and reinstalling. No engine light on all the time. No acceleration, and today got etc engine failure mode. Stopped car, restarted and would then go more than the 15 MPH in failure mode . But still doesn't accelerate like it should.”
NHTSA complaint #10343506, filed 2010-07, 49,000 miles“Stalling,jerking surges. Three times the car just came to an abrupt stop. Had to have it towed. My 77 year old mother was left terrified. Overheated jerks into gear. Ford replaced engine coil,but said they could not replace all at once we would have to continue to break down in order to fix each coil. The car always jerks and surges. The results are that we can not go on the freeway for fear of breaking down. No long trips etc.”
NHTSA complaint #10342907, filed 2010-07, 50,000 miles“My 2004 Lincoln LS has a coil problem. It cuts out and misses and then shuts down. I have had 3 coils replaced and also the throttle body and spark plugs changed. It has 85,000 miles on it now but this has been a problem since it was in the 40,000 range. The dealer will replace them if they can get them to fail while they are checking it but they don't always act up at that time. I had to pay $114.00 for a diagnostic check last week and they could not fine anything wrong. It still cuts out and is generally unreliable. …”
NHTSA complaint #10341066, filed 2010-07, 85,534 miles“I have a 2004 Lincoln LS that started to run rough so I replaced the air filter. This did not help so next I replaced the spark plugs. This did not help. The things that I have done up to this point started because my car started missing and running rough however I have found out that it was just the beginning of a bigger problem in that the car was and is pumping gas into the engine and air intake to the point that it is coming out of the exhaust system in an amount that causes a steady stream and it pools under the car. …”
NHTSA complaint #10329850, filed 2010-05, 70,000 miles“I have had my 2004 Lincoln LS in the shop at my local ford dealership on numerous occasions. Starting at around 80,000 miles on it, I had a variety of problems on it which cost me several thousand dollars. But most recently and the biggest problem that I have now is with it running hot. As a matter of fact, this is my 5th time taken to the shop for this same problem. They replaced my thermostat for $200, next trip they replaced my coolant reservoir $200, 3rd trip they replaced an 0 ring $310 and now it's in there right now which the same problem. …”
