2003 Lincoln LS Problems

Engine -- Verified

Erratic engine coolant temperature or intermittent overheating can be caused by corrosion inside the water pump. The impeller may spin on the water pump shaft or the impeller may corrode. Either condition reduces coolant circulation resulting in engine overheating.

Exhaust & Emissions -- Verified

In high dust areas, problems with the EGR system are common. The filter for the EGR solenoid may plug and cause the EGR to activate when it should not; this can cause the engine to stall. The dirty filter should be replaced to correct this concern.

Exhaust & Emissions -- Verified

An exhaust leak may develop in front of the catalytic converter. This type of leak should be corrected as soon a possible to avoid damaging the catalytic converter.

Suspension & Steering -- Verified

Even though the manufacturer does not call for regular servicing, our technicians recommend servicing the power steering fluid regularly.

Engine -- Verified

Due to age and possible damage during removal, it is recommended to replace  the spark plug boots when replacing the spark plugs,

2003 Lincoln LS Reviews

I recieved a 03 ls from a customer to do an easy tune-up. but after looking into it found most all easy items changed by previous owner and it still will not drive down road. This is the 3rd ls I have seen like this with a MAJOR problem and hope people stay away from them.


I just bought a 2003 Lincoln LS, its a nice car BUT... The service light comes on at least once a week, about a month after i bought it the engine light came on and i had to have all the iginition coils replaced. now a week later the engine light is on again and my car is doing the same thing. when im at a stop sign or a light i can feel my car lightly shaking and i can hear some noises from my engine. What should i do?

I can't get enogh of the Lincolns. I bought a 1998 Navagator in 2000 and it has been a dream SUV. Not good on the gas but great to drive and tow our travel trailer with. So for my wifes B-day I got her this 2003 Lincoln LS in 2008 and it still only has 43000 miles on it. They our the best cars we have ever owned. Top of the TOP.

Never buy a ford never buy a chevy I know ford makes Lincoln but Lincoln is far superior to ford and all others.

One of the nicest vehicles I have ever owned. Very nicely appointed with technology and features. Will keep it until it won't goany longer...
