Open the full vehicle complaint log (all categories)While driving vehicle the engine shut down for no apparent reason. Light came on said do not attempt to drive, not safe. Was able to get car to a safe area. Was able to restart and get the car home. Brought the car to the dealer, said battery was dead, found water in the truck where the battery is located
The catalytic converters(2) failed and need replacement. My mechanic diagnosed the problem and agrees with the scan code that was reported, a P0430. The check engine light is constantly lit and cannot be turned off with this fault code, according to my mechanic erasing the code will just bring it back shortly, and I have witnessed this. I have a document from Ford Motor Co. that shows my car, Lincoln MKZ, the build date from 2013-2015(1/24/2015), the Assembly plant of Hermosillo, saying that the dealer should replace the cats at no charge to the customer. Yet the dealer and FoMoCo say my cars VIN is not in the range for this repair. Why?
MY 2015 MKZ STARTED HAVING PROBLEMS IN SEPTEMBER 2020 WHEN THE CHECK ENGINE LIGHT CAME ON AS WELL AS THE INDICATOR FOR LOW ENGINE OIL PRESSURE, BOTH COMING ON WHEN THE CAR IS IN MOTION. WE PURCHASED THE EXTENDED WARRANTY WITH THE VEHICLE AND AFTER TAKING IT TO FORD AUTO NATION IN PANAMA CITY, THEY TOLD US IT WAS THE CATALYTIC CONVERTER. THEY DID NOT TEST WHY THE LOW ENGINE OIL PRESSURE INDICATOR LIGHT CAME ON, ONLY STATING IT WAS DUE TO THE CATALYTIC CONVERTER. I HAD TO CALL THEM TWICE TO EVEN GET AN UPDATE ON MY VEHICLE AS NO ONE WOULD CALL ME REGARDING THE ISSUES. WE THEN BROUGHT IT TO THE LOCAL MECHANIC WE USUALLY USE AND THEY STATED THE CAR HAD TWO EMISSION RECALLS/BULLETINS; ONE FOR THE CATALYTIC CONVERTER AND THE SECOND FOR THE POWERTRAIN CONTROL MODULE REPROGRAMMING ( WHICH I HAVE COPIES OF). AFTER TAKING IT BACK TO FORD AUTO NATION PANAMA CITY, THEY STATED THESE TWO RECALLS DID NOT APPLY TO MY VEHICLE AND WOULD NOT HELP US, EVEN AFTER GIVING THEM COPIES OF SUCH PAPERWORK. THEY STATED THAT JUST BECAUSE THE RECALLS/BULLETINS PULLED UP WITH MY VIN NUMBER, IT DID NOT MEAN THOSE WERE APPLICABLE TO MY VEHICLE. SINCE THE INCIDENT WITH FORD AUTO NATION PANAMA CITY, MY VEHICLE HAS BEEN TO THE LOCAL MECHANICS SHOP 3 TIMES FOR REPAIR TO THE OIL PRESSURE SWITCH, 2 DIFFERENT O2 SENSORS (FRONT LEFT AND BACK RIGHT) ALONG WITH CHANGING OUT OF SPARK PLUGS AS THE CORRECT ONES WERE NEVER INSTALLED AND A HUGE GAP WAS FOUND BETWEEN THEM ( I PURCHASED THIS CAR ONE YEAR AGO). THE CODES FOR THE CHECK ENGINE LIGHT ALL THREE TIMES HAVE SHOWN THE O2 SENSORS AND CATALYTIC CONVERTER. I WANT MY CAR REPAIRED PROPERLY AND MY FUNDS REIMBURSED AS THIS WOULD NOT HAVE HAPPENED IF FORD AUTO NATION PANAMA CITY WOULD HAVE REPAIRED MY VEHICLE PROPERLY WHEN WE PROVIDED THEM THE PAPERWORK REGARDING THE EMISSION RECALLS/BULLETINS.
DRIVING HOME AT RUSH HOUR AND CAR SUDDENLY LOST ENGINE POWER, NO RESPONSE WHEN PUSHING ACCELERATOR, MULTIPLE DASH LIGHTS CAME IN. UNABLE TO TRAVEL MORE THEN 5-MPH.HAPPENED MULTIPLE TIMES IN THE FOLLOWING HOURS, TOWED TO DEALER.
