What owners report
Owners of the 2004 Lincoln LS most often describe ignition coil and throttle body problems that put the car into a reduced-power "ETC engine failsafe" mode, sometimes with stalling or surging. Airbag deployments that owners say happened without a collision, harsh reverse or 3-4 transmission engagement, and intermittent electrical drains round out the picture. Many of these reports come in between roughly 40,000 and 90,000 miles.
- Air bags
Airbags deploying without a crash
- 18 complaints (20%)
- median 51,000 mi at 5.1 yrs old (16 state mileage)
- 12 mention a crash, fire or injury
- filed 2004–2017
Complaints describe side curtain or seat airbags deploying while the car was being driven normally, with no impact, sometimes at low speed and sometimes at highway speed. Several owners report injuries from the deployment, and some say the dealer attributed the deployment to a prior impact they were not aware of. A few complaints instead describe airbags that did not deploy in a collision. Reported from under 1,000 miles up to about 200,000 miles, with several under 35,000 miles.
What to check: Ask whether the car has any airbag warning light history or prior airbag repairs, and have a pre-purchase inspection check for stored airbag module codes and signs of previous deployment.

NHTSA complaint #10086398, filed 2004-08, 3,972 miles - Vehicle speed control
ETC failsafe / reduced power from throttle body
- 53 complaints (58%)
- median 70,836 mi at 6.6 yrs old (45 state mileage)
- 4 mention a crash, fire or injury
- owner-quoted repair $900 (median of 5 quotes)
- filed 2004–2020
Complaints describe the car dropping into "ETC engine failsafe mode," where acceleration is limited to about 15-30 mph until the car is shut off and restarted. Owners often link it to throttle body trouble; some had ignition coils replaced first, and several report the throttle body was replaced or diagnosed as the culprit. A number say the problem reappeared after repair, and some mention a nationwide parts shortage that left the car at the dealer. Reported from very low mileage up to about 120,000 miles, with many complaints in the 35,000-90,000 mile range.
What to check: Ask whether the throttle body has been replaced and whether the electronic throttle control lamps or codes P2106/P2135 have ever appeared. A test drive should include steady acceleration and a restart to confirm the car does not drop into failsafe.

“Driving down the side street and my car goes into limp mode. Reads etc .start up will move about 1/4 of the block and does it again. Had to keep turning it off and on to get home.once stop in the middle of the intersection. From what I have seen this is not unusual for LS. This is a safety concern. Have not got my car fix because it is very expensive to fix.”
NHTSA complaint #10478546, filed 2012-10, 92 miles“Normal clear weather driving down busy street when care suddenly slowed down almost resulting in a collision with vehicles behind me. The engine stopped , I restarted with very limited drivability the etc failsafe mode kicked in for no apparent reason this issue must be addressed before someone is seriously injured.”
NHTSA complaint #10820770, filed 2016-01, 105,000 miles - Engine cooling
Misfire, rough running and stalling (ignition coils)
- 24 complaints (26%)
- median 73,550 mi at 6.7 yrs old (22 state mileage)
- 2 mention a crash, fire or injury
- filed 2005–2013
Owners describe the engine cutting out, missing, running rough, surging or stalling, often with a flashing check engine light and misfire codes. Complaints frequently name the ignition coil-on-plug assemblies; in several cases the dealer replaced only the coil that failed rather than all of them, so owners say they had to return repeatedly. Some report the dealer could not reproduce the problem or found no fault codes. Reported across the range from about 40,000 to over 120,000 miles, in normal driving conditions.
What to check: Ask for service records on ignition coils and spark plugs, and check for a stored or pending misfire code. A service bulletin notes extended warranty coverage on coil assemblies for these years.

“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 - Transmission and drivetrain
Harsh or delayed reverse and 3-4 shifts
- 14 complaints (15%)
- median 57,500 mi at 5.0 yrs old (12 state mileage)
- filed 2005–2020
Owners report hard engagement when shifting into reverse, harsh 3-4 upshifts and jerking when braking, with some saying the car lost power or would not move after stopping. Some complaints reference a mailed notice about transmission fluid installed at the plant that could cause delayed or harsh reverse engagement, and say the dealer added an additive or changed the fluid. Mostly reported between about 45,000 and 90,000 miles, in ordinary driving.
What to check: Ask whether the transmission fluid additive or fluid service described in the customer satisfaction program was performed, and drive the car through several reverse engagements and 3-4 shifts before buying.

“I own a Lincoln LS v8 with 55,000 miles. When I shift into reverse it creates a harsh sound, like the transmission is going to fall out. My check transmission light came on will be taking it to the dealership. I have been researching transmission problems on LS and seems to be extremely common manufacturing problem. Something must be done!”
NHTSA complaint #10322118, filed 2010-03, 55,000 miles“In nov 2008,while driving on a very busy street, I noticed the vehicle shifting very hard and at times causing a harsh jerk. As I attempted to make a left turn on a very busy intersection to return the vehicle home, the vehicle lost all power and the error message etc engine failsafe mode displayed on the screen. Thankfully the car slowly coasted across the 3-lane intersection without causing an accident. I had the vehicle towed to the Lincoln dealership and they stated that the throttle body need to be replaced. …”
NHTSA complaint #10256099, filed 2009-01, 71,000 miles - Engine cooling
Coolant loss and running hot
Mentioned in 6 of 60 sampled complaints
Complaints describe the engine running hot repeatedly, with owners returning to the dealer multiple times for thermostat, coolant reservoir and O-ring replacements without a lasting fix. Some report overheating alongside jerking or stalling complaints, and others mention the air conditioner blowing hot on one side. Reported mostly from about 55,000 to 90,000 miles, often on cars with a longer service history.
What to check: Check the coolant level and look for residue around the reservoir, thermostat housing and hoses, and ask whether coolant parts have already been replaced. Watch the temperature gauge during a test drive in traffic.

“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. …”
NHTSA complaint #10328064, filed 2010-04, 80,000 miles“The car loses power and goes into fail safe mode, at 65 and lots of traffic getting over is not safe! I've spent thousands on new coils, computer, gas pedal, you name it but ford does not know how to fix it!”
NHTSA complaint #10416930, filed 2011-08, 117,000 miles
Buying note. A 2004 Lincoln LS can be a pleasant driver, but the complaints suggest checking the throttle body, ignition coils, transmission behavior and airbag history carefully before buying, and asking for service records. A pre-purchase inspection that scans for stored codes is worth the cost on this model year.
