While driving in sub-zero temperatures engine sounded horrible called for a tow to village Ford kept vehicle for 3 weeks then said need new engine but warranty voided because engine severely deprived of oil. Service tech said not correct because there was oil in it asked for my oil change receipts I had 4 receipts 2 from oil change shop and 2 from my brother Ford would not accept oil changes done by my brother allowing them to say that I did not change oil enough not maintaining the vehicle properly voided my warranty southgate lm said I needed new engine and damage was caused by a camshaft seizing inside the engine due to the vehicle engine timing being off oil in the vehicle appears very dirty and unfortunately is the culprit of the timing being off I did change the oil but Ford chose not to recognize two of my changes there was never any indicator lights on my dashboard such as a check engine or an oil lamp indication to warn that the oil is low or that the engine is having trouble (as in trouble getting oil) car has been in a Ford shop for nearly 6 weeks by the time I get it back southgate Lincoln Mercury will replace the entire engine and all associated parts for which I will be charged $6000 00 meanwhile I have no assurance that this will not happen again since there was no early indication of trouble I have never been told by Ford nor do I see it in any of their paperwork that they will not count an oil change as valid if it is not done at a service shop this engine failure caused a large risk to me and my three children because with the record-breaking cold temperatures we could have suffered hypothermia or frostbite very quickly had I not stopped the car in a subdivision where we took shelter in a home we could have suffered catastrophic harm had I pulled out into oncoming traffic at the time the engine started to sound bad and lose power.
