“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.”

“Brand new battery in car. Come out to start car. Battery is dead. My mechanic has car for three days. He tried to find a short. He instructed me to make sure all doors are completely closed and lights are all out. This was after multiple dead batteries. I made sure of all the above and still came out to dead batteries. I manually turn off the lights as I came out to them being on after I had watched them dim and go out. I replaced the new battery with another new battery and I am still having problems.”

“The horn on my car does not blow at times. The dealer said to simply push harder. Dealer checked another similar car on the lot and said it was the same. When the horn is needed in traffic situations you don't have time to think push the horn harder . My car is new and this should not be a problem.”

“My 2004 Lincoln LS goes into etc engine failsafe mode which doesn't allow the car to accelerate anymore and causes the car to slowly slow down. This happens all the time on my car. Probably once every three miles I drive on average but it happens most when the car is accelerating. I have almost been in numerous accidents because of this problem. I have replaced ignition coils and the throttle body and nothing seems to help. I am scared this car is going to get me killed the next time I merge onto the freeway. …”
