2005 Lincoln LS Owner Comments

problem #9

May 042013

LS 6-cyl

  • 34,400 miles


I was completely stopped at a red light with my foot on the brake. The car suddenly lurched on it's own. My reaction was to apply both feet to the brake with force. In spite of that, the vehicle continued to crawl and it rolled into the intersection. I was hit by an oncoming car. My car was totaled.

The contact owns a 2005 Lincoln Ls. The contact stated that while driving, the contact decelerated and the vehicle erroneously accelerated. The contact shifted into park to stop the vehicle. The contact also stated that the failure recurred several times and eventually became permanent. The vehicle is currently being diagnosed by the dealer. The manufacturer was notified of the failure. The approximate failure mileage was 100,000.

My 2005 Lincoln Ls has been going into an etc failsafe mode almost every other day for last four months. Dealership has told me it is a faulty accelerator pedal sensor. However, this part was and continues to be on a "national backorder". I have avoided countless crashes due to this failure while merging into traffic. Once the etc failure comes on, I lose all accelerator power and merely coast in an attempt to get off highway so I can restart the car. On one particular day this happened 4 times over the course of driving about 15 miles. I am putting the incident date as when I took it to dealership last however this issue is on going.

When car accelerate, the care goes into an etc fail safe mode and shuts down. This almost caused an accident on two occasions. The dealership knows it is an issue, but says I will have to fix.

  • 65,000 miles
The car will suddenly surge or die out while driving. Can occur at any time while driving, did it to me multiple times, whether in idle or on the highway going 50+mph. I am trying to get the part replaced from the dealer. The part is on backorder, seemingly there is a large number of these going bad and not enough new ones to go around. The part the dealer is telling me went bad is the throttle body.

Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6) last night my 2005 Lincoln Ls had runaway acceleration when I put it into reverse. I couldn't get it stopped until I was out of the driveway and halfway into the street. I almost hit a tree. I know that if I take it into Lincoln, they will deny any issue. [xxx]

On July 4, 2009 while traveling on a major highway driving at the speed of 60 mph the acceleration stopped functioning without warning. This was the first time this issue ever occurred. To correct the problem the car was taken to a Ford dealership to repair the problem. I was told that the throttle body needed to be replaced. The throttle body was replaced and while leaving the dealership on another major highway the issue happened 3 times after the repair was said to be completed. Both times the issue occurred my family and I was in a near fatal accident. The car was returned to the dealership on that same day. After a day of diagnostic the dealership could not explain to me what was causing the problem. Finally, the dealership called and stated that a radio frequency was causing the problem. I was also told that the there was a problem with the coils. At this point I don't think the certified technicians or the dealership know how to repair the issue. I do know that the service manager want me to keep paying money until they stumble upon a solution. I refuse to put my family on the highway a third time with this ongoing issue. Maybe next time we won't be so lucky.

problem #2

  • 63,295 miles
The contact owns a 2005 Lincoln Ls. The contact stated that the accelerator pedal was becoming stuck while attempting to operate the vehicle. While driving less than 65 mph, she felt as if something were stuck underneath the accelerator pedal and it would resist force. The dealer could not duplicate the failure; however, the diagnostic determined that the throttle failed. The failure persisted and the vehicle was taken to an independent mechanic, who installed a throttle actuator control, gasket, and accelerator pedal sensor to remedy the failure. After the repairs, the parking brake warning indicator illuminated on the instrument panel. The mechanic assured her that the brakes were replaced and the instrument panel displayed a faulty warning message. To date, the failure still cannot be duplicated and the contact is awaiting the arrival of a part that would apparently remedy the failure. The failure mileage was 63,295 and current mileage was 66,000.
