Open the full vehicle complaint log (all categories)Purchased vehicle at the end of 2018 and this is the third time I have had to replace the horn. It's not a fuse, it's not wiring, it is the actual horn that either shorts or dies with no notice.
Trunk randomly pops open during driving. Or when you put it in gear.

DRIVING DOWN THE ROAD... ABS, BRAKE, TSC LIGHTS KICKED ON AND THE CAR JERKED TO THE RIGHT-HAND SIDE AND SLOWED DOWN ABOUT 10MPH... AS I KEPT GOING IT LIT UP AGAIN AND JERKED HARD... AS I GOT SPEED TO ABOUT 55MPH DID IT A FEW MORE TIMES BEFORE I FINALLY SHUT THE CAR OFF AND HAD THE DEALERSHIP COME GET IT..
FOR THE PAST 6 MONTHS, THE BRAKE LIGHTS DO NOT COME ON PROPERLY AND OCCASIONALLY THE BATTERY DRAINS. WHEN THIS WAS LOOKED INTO, IT WAS FOUND TO BE A BAD BODY CONTROL MODULE. THIS SEEMS TO BE A COMMON PART FAILURE ISSUE FOR FORD. WE NEED THIS REPLACED/FIXED. BRAKE LIGHTS NOT WORKING IN STATIONARY POSITION, WORK SOMETIMES WHILE MOVING AND BATTERY TO CAR DRAINS WHILE STATIONARY OVERNIGHT. *TR
THE ELECTRICAL SYSTEM SHUT DOWN COMPLETELY ON THE 2018 FORD FIESTA. NO POWER, NO ENGINE, NO LIGHTS, NO ELECTRICAL COMPONENT FUNCTIONED. NO HAZARD FLASHERS IN RUSH HOUR TRAFFIC AT THE INTERSECTION OF AN INTERSTATE HIGHWAY AND A STATE HIGHWAY. THE CAR COASTED AND I STEERED IT BETWEEN LANES TO AS SAFE A SPOT AS I COULD REACH. THE SITUATION WAS DANGEROUS WITH A HIGH POTENTIAL FOR HARM. FORTUNATELY NO ONE WAS HURT AND NO ACCIDENTS RESULTED. AFTER A TWO WEEK REPAIR ON A NEW CAR I HAD OWNED FOR ONLY TWO WEEKS THE CAUSE WAS FOUND TO BE A BROKEN CABLE CONNECTOR UNDER THE BATTERY.
