Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Etc engine fail safe - electronic throttle control replaced with oe... continues to produce an etc engine fail safe and no code(s) specifics for faulty coils (or which coils) (3 bad coils & passenger side valve/spark plug cover gaskets) or possible faulty alternator.

The contact owns a 2005 Lincoln Ls. The contact stated that the ignition coils were replaced frequently before 100,000 miles. The vehicle was taken to the dealer for diagnosis where it was stated the ignition coils misfired and needed to be replaced. The vehicle was repaired but the problem persisted. The manufacturer was notified. The approximate failure mileage was 100,000.

While traveling on a divided highway at approximately 35 mph my car abruptly slowed to about 20 mph causing vehicles behind me to brake and/or swerve around me. A "wrench" warning light came on and I found after getting to a safe spot and stopping, that the owner's manual stated that the car was in the "limp mode" where it would not go any faster and needed to be taken to my nearest Ford dealership. After stopping the car I shut if off and upon restarting, the warning "wrench" light was off and the car acted normally. I contacted a number of dealerships and mechanics and found that it's a somewhat common problem, but the fix could be anything from a bad transmission solenoid to a complete fuel/computer/ignition redo for $4500 to $6500. Having this happen on a rural road is one thing, but if it happened on an expressway with traffic at 75 mph plus, could quite possibly be lethal.

Since purchasing this car, its been nothing but problems. The problems I've experienced aren't any different from all the other Ls owners. Coil packs going bad, the A/C blowing hot air, the car going into fail safe mode while on the freeway, the smell of gasoline inside the car. It looks like these issues have been going on since Ford started producing the car. Now wonder they needed bailout money. I got in my car this morning and it went into fail safe mode 3X's before I could get out of the drive way! all of these issues with this car dating as far back as 2001, and no recalls, C'mon man. My tax dollars went to help out this company!!!! [xxx]shame!!!! this is my first and last time buying a Ford! information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I have three major problems with my 2005 Lincoln Ls. The first problem is I have a hard reverse and the gears stick between 30-35 mph as I accelerate. Sometimes it has a hard bump once it starts accelerating! the second problem is that I have replaced two ignition coils within a year apart and now I have two more ignition coils that need to be replaced per P0354, P0301and P0304.I have replaced the throttle bottle, but the limp home sign has occured twice since then causing the car to decelerate!! the third problem is the catalytic converter per P0420. I purchased this car in 2009 with less than 50,000 miles, less than a year the transmission started slipping!
