2003 Lincoln LS Owner Comments

I purchased my 2003 Lincoln Ls June/2015. Excellent condition, 35,000 miles. Interior immaculate condition leather seats and carpet virutally untouched. Underneath hood the same, hadn't look as if been driven. Exterior body and paint again excellent. The car appeared as if it had stood still in time. Upon investigation, only one owner of the vehicle who'd maintained a first class maintenance record. Over the last week the vehicle my wife was driving she said while driving the vechicle began to stall while she was accelerating in traffic. She stated she was able to get it out the street but in doing so the engine revved up and shut off. Over the past few days on several occasions the vehicle replicated the exact same tendency with me. Stalling, hesitating during acceleration to the point of shut down in the middle of traffic. In motion on a very busy city street. Engine light also came

The contact owns a 2003 Lincoln Ls. While driving approximately 35 mph, the engine stalled and the vehicle restarted independently. The failure recurred numerous times. The vehicle was towed to a dealer where it was diagnosed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 200,066. The VIN was not included.

While driving the car it misfires it doesn't want to go on acceleration..it is leaking oil into the spark plug wells and affecting coils..there was a extension warranty on these parts.but it was 10 years or 100000 mile. I didn't purchase this car till after it already had more than 100000 miles so I was unaware of these extensions and time frames..I spoke with Ford/Lincoln and basically told the extended warranty would not cover.I feel this should be a recall not extended warranty.

Car hesitates on acceleration since it was new. Took the car to the selling dealer and they could not find a problem. The condition got worse. When traveling down the highway the car starts bucking and misfiring. Took the car back to the selling Lincoln dealership (sesi Lincoln Mercury). They dealership said the drivers door needed adjustment. This made no sense to me and did not fix the problem. The car went out of warranty shortly after that. Now check engine light comes on intermittently and car hesitates, bucks, stalls and runs rough, misfires at highway speeds, and mil starts flashing. The cowl plastic piece has a poor seal on it that lets water onto the engine electrical system. Ford issued a technical service bulletin that addresses this issue and Ford admits that seals need to be replaced. This may not be the only problem with this cars electrical system, but it is a big problem. This is a design defect, nothing a customer can do to prevent this. Ford should have recalled these cars and fixed them at no cost. The fact that their dealerships were hiding the real reason for this misfire and not repairing the vehicles under warranty is breech of contract. Ford should be fined and punished and forced to recall and repair all of these cars. I am an ase master mechanic. I teach automotive service technology at the college level. This should not be happening. The car was garage kept and very well maintained, it looks new. I found that # 6 cylinder had a P0306 coil misfire dtc. I had to remove the intake manifold just to see the coil on plug set up on the passenger side bank of engine. Turns out there is poor sealing of the windshield cowl area and water runs directly onto the engine and engine electrical system. The water shorts out the coils, spark plugs, computer and electrical system. The car is not safe to drive. This can happen at any time especially when wet.

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.
