2003 Lincoln LS Owner Comments

Hello, I bought a 2003 Lincoln Ls and I'm getting a message on the dash that is saying etc fail safety mode and the car is not able to go over 30 mph, and has very slow pick up and is running very hard. I have found that sometimes if I turn the car off/on the message does not come up the car drives normally. I have tried replacing the throttle body after getting the check engine light came on with to codes P0207 and P02110 and I'm still having the same problem. I have read allot of complaints about this problem with fix.

Shifts hard, when in 20-30 mph, in gear 2 and 3. after diagnostic, dealer said it may be transmission, but they have to tear it apart. If bands, torque converter, or solenoid pack they have to tear down and rebuild. He did say that one of the solenoids went outer if bands were bent, they would have to rebuild the transmission for a cost of $2500 - $3500. I have read all over the internet where people are complaining about hard shifting and transmission problems. It seems that the part was defective by design. One person said that they bought a kit that fixes the design flaw - 5rw master servo bore repair kit (Ford 5R55W/S/N). It is not made by Ford, it seems they are too cheap to fix the real problem. They should listen to peoples concerns. I am also going to call the 800 number for Ford Lincoln and send them a letter. Would use with any tranny rebuild. The final cost of the repair is now at $4000. Yikes.

Car starts and runs rough, then surges forward. Have to hold the brake hard. Car then stalls and gives "etc engine failure". upon restart car will run fine for a while. Dealer cannot identify the problem, as it does not consistently throw a code, replaced the coils

The contact owns a 2003 Lincoln Ls. While driving at 20 mph, the ect engine warning light illuminated as the vehicle began shaking excessively. The contact moved the vehicle from the roadway and shut off the engine. When restarting, the vehicle resumed normal operation. The contact stated the failure would occur intermittently. The dealer advised there was a full throttle failure. The vehicle was not repaired. In addition, the transmission warning light would intermittently illuminate. The vehicle was not taken to the dealer for diagnostic testing of the transmission and there were no repairs. The failure mileage was 52,000 and the current mileage was 82,000.

: the contact stated the vehicle had just been parked with the brake pedal depressed and the vehicle accelerated forward. The vehicle went over a curb, hit a tree, and stopped after hitting two other vehicles. A police report was taken at the scene. The vehicle was towed to the dealership, but they were unable to determine the cause of the problem. The vehicle had accelerating problems while driving at various speeds prior to this incident.

LS 6-cyl

  • Automatic transmission
  • 8,100 miles
Tried to start vehicle and vehicle would not stay on and would not accelerate.contacted dealer and arranged for tow truck. On 6/3/04 contacted dealer for status report and to arrange for alternate transportation. Service rep. States that vehicle throttle assembly failed therefore not allowing oxygen into the engine. Approximate part arrival is 3 days. I do belive this vehicle is a lemon. Never purchasing another Lincoln.
