Electrical system
13 reports1 related recall
“During a manufacturer-mandated software module update, North Central Ford (Plano, TX) bypassed continuous power supply safety protocols. This negligence caused a voltage drop, interrupted the software flash, and completely corrupted the Accessory Protocol Interface Module (APIM). The dealership returned the vehicle to me, stating the update was complete. The corrupted module failed to power down, causing a severe parasitic drain that completely killed the battery overnight, leaving the vehicle immobilized and immune to jump-starting. The APIM is completely corrupted. The disabled vehicle was towed back to North Central Ford and remains available for immediate inspection. Safety Risks: The corrupted APIM permanently disabled the federally mandated backup camera (violating FMVSS 111) and touch-screen climate/defroster controls, creating severe rear and forward visibility hazards. The module's failure to sleep causes a continuous parasitic battery drain that has already stranded me and introduces a high risk of sudden electrical failure in traffic. Dealer Confirmation: North Central Ford's paperwork confirms they caused the failure. Their Day 1 intake Multi-Point…”

“While driving on interstate 271/480 my check engine light started flashing and my car suddenly died putting me in harms way as I tried navigating 3 lanes to get to the berm. It was towed to 2 different Lincoln dealerships where they both confirmed the engine lost compression and would need a full replacement. This vehicle is only a 2017 and 100K miles and shouldn't have total engine failure at that age. I read articles on NHTSA investigating Ford engines and feel this may have a similar engine issue and is worth investigating. Please let me know how I can assist.”

“10 MILES AFTER STARTING OUR 2017 LINCOLN MKX IT SUDDENLY GAVE ME THE WARNING CODE OF ERROR: VEHICLE SHUTTING DOWN NOW. THE CAR COASTED ACROSS 5 LANES OF SPEEDING TRAFFIC. I ALMOST DIED WITH OUR SMALL CHILD IN THE CAR. THE CAR RESTARTED FINE ON THE SIDE OF THE ROAD. SANDERSON LINCOLN TOWED THE CAR AND DID THE BARE MINIMUM TESTS ON THE CAR PER THE MANUFACTURER STANDARDS. I REQUESTED THEM TO DO MORE AS THIS EXACT SAME SITUATION HAS HAPPENED TO OTHER LINCOLN OWNERS MULTIPLE TIMES IN ONE CAR. THERE HAS ALSO BEEN A RECALL ON THIS ON PREVIOUS YEARS. THIS VEHICLE ALSO HAD SOME STRANGE ACCELERATION ISSUES WHEN WE INITIALLY BOUGHT IT AND IT WAS DISMISSED BY THE SERVICER. LINCOLN CUSTOMER SERVICE NOW TOLD US WE ARE OUT OF LEMON LAW AND THEY CANNOT HELP US. DUH. LINCOLN CUSTOMER SERVICE ALSO DID SHADY THINGS TO US. THEY WOULD CALL US AT 11PM FLORIDA TIME FROM A DUMMY PHONE LINE SO THAT THEY COULD "SAY" THEY CALLED US. THE SERVICER REPLACED OUR BATTERY AND CALLED IT A DAY. INITIALLY THE MANUFACTURER SEEMED OUTRAGED THAT THE BATTERY COMPLETELY FRIED ON THE VEHICLE DURING TESTING....THEN THEY SUDDENLY CHANGED THEIR TUNE AND SAID WE WERE OUT OF LEMON LAW IN OUR STATE.”
