“the service engine light continues to turn on. the timing belt continues to fail and has already been replaced once. the camshaft on both sides have been replaced. the solenoids have also been replaced and the diagnostics codes still pop up (p0022) (p0021) are just some that i can remember. the engine does not have enough power on the driver side and throws the timing belt off which causes the loud rattle coming from the engine. when reaching the speed of 40-45 mph the truck begins to shake. recently in november 2023, when fueling up with gas , the truck began to shake and not respond. when accelerating, the truck takes off very slowly and the gears dont kick in on time. when the gas light comes on , the truck begins to function well. but as soon as i put gas again. it feels like the truck is going to fall apart. the driver door gets stuck when trying to open from the inside. the back door on the left does not open from the outside. the gear handle can be moved up and down while the truck is not turned on. please help!!”

“FORD HAD A RECALL FOR BROKEN SPARK PLUGS & A CLASS ACTION LAWSUIT ON THIS VEHICLE. FORD HAS FAILED TO FULLY COMPENSATE US & TOLD ME HARDLY NO ONE WOULD RECEIVE COMPENSATION. WE REPLACED THE PLUGS WITH FORD APPROVED REVISED PLUGS AT FORD WITH @ 149K MILES ON 11/2015. THE ENGINE CODES OR PROBLEMS WOULD COME UP NOW AND AGAIN & WE HAD IT INTO VARIOUS VENDORS.. 2/ 2017, DRIVING BACK TO WYOMING I CAME UP AN I WAS UNDER LOAD (HAULING A TRAILER) AND THE AUTO ALMOST DID NOT MAKE IT HOME OR UP A GRADE. WE TOOK IT IN TO REPLACE THE COILS. THE VENDOR, MIDWAY MOTORS REPLACED THE COIL & NOTICED THE NEW REVISED FORD APPROVED SPARK PLUG 5 WAS BROKEN, AND PLUG 6 ALSO SHOWED A CODE, (MILEAGE 172627 MILES). THE ENGINE WAS DAMAGED SO WE TRADED THE FORD IN FOR A DODGE. MY POINT FORD HAS NOT FIXED THE ISSUE & IS DECEIVING THE PUBLIC. AND 2ND LAWSUIT CLAIM FORM IS [XXX] . THE VEHICLE WAS KEPT IN LIKE NEW SHAPE PRISTINE. I WAS SAD I HAD TO TRADE IT IN BUT DID NOT FEEL SAFE. I THINK YOU NEED TO KNOW HOW FORD IS PRACTICING AND NOT HANDLING ETHICALLY, LEGALLY, OR PROPERLY; BOTH THE CLASS ACTION LAWSUIT AND ALSO THE (REVISED SPARK PLUGS ARE ALSO FAILING). YES I HAVE DETAILED DOCUMENTS!!…”
