2006 Lincoln Navigator Owner Comments

problem #5

2006 Navigator would keep misfiring even after coils were replaced. Dealer first reports it was a valve. After inspection valve was not the problem but a burnt head was the cause. Head went to outside shop for repair but the shop says now that the problem might be lower in the engine. A new engine is being suggested by the dealer but the warranty company may not pay. Car has 44000 miles currently.

Spark plug in 2006 Lincoln Navigator popped out! serviced by Ford/Lincoln/Mercury and said nothing was wrong with ignition system. Spark plug replaced and cars is barely drivable. It often stalls at idle RPM.

The contact owns a 2006 Lincoln Navigator. During routine maintenance and a tune-up, he received a call from the mechanic stating that they broke part of the spark plug into the engine cylinder while trying to change them. The dealer would not assume liability for the repair. The necessary repairs were performed on the vehicle at the owner's expense. On a separate occasion, while driving at speeds of less than 35 mph the vehicle stalled without warning. The vehicle was towed to the dealer where they found the fuel pump computer module failed. The vehicle was repaired at the owner's expense. The failure mileage was 96,000 and the current mileage was 100,000. Updated 11/22/10 updated 11/23/10

The Lincoln dealership broke 5 of my 8 spark plugs while trying to change them. I was told that I have to pay since this has happened. This is a known problem with Ford engines. Please reference the following link. www.fordproblems.com/spark-plug-ejected-from-engine.shtml.
