“The shifter knob on my 2003 Lincoln Aviator broke off. The shifter was locked in place in drive and you are unable to shift into any other gear except the gear you're in. It seems that a very cheap plastic piece broke under the shifter knob and the dealer quoted me $1200 dollars to replace the entire shifter assembly. I have checked online and seen that this is a very-very common problem among owners. There is no recall for this issue, but this is surely a severe safety issue. I am not sure how many complaints it takes but this is a horrible safety issue. …”
NHTSA complaint #10478178, filed 2012-10, 143,145 miles“The gas pedal on my 03 Lincoln Aviator comes loose. The first time it happened my gas pedal got stuck and I had to switch into neutral and physically lift it. I had the problem fix but it has come loose again. The mechanic said that Lincoln doesn't have the part and that this happens all the time.”
