Hi, I purchased my 2006 ford explorer in 2019 from a mechanic lot. Since then Iâve changed the muffler, all 4 of the o2 sensors. Recently, after changing parts like the cylinder, spark plugs and wires as well as another set of o2 sensors and the EGR Valve, Mass Air flow sensor and the EGR sylenoid valve I have been getting check engine light with the emissions code not passing inspection. At this point my registration is at hand and the mechanics that change the parts canât seem to understand why the check engine light did not go off. However an additional code came on in regards to the heater. As per PEP Boys mechanic shop and Auto Zone the emissions keep failing and may need a new…

Complete failure of the powertrain electrical harness. Heat degradation to wire insulation has exposed all conductors. Several other owner operators have experienced the same issue wherein the Dealer has attempted repair of existing trouble codes, by replacing sensors, modules and components. Problems range from vehicle shut-off at speed, vehicle fires, no-start and failed PCM modules due to short to power or short to ground. Based on my findings, this specifically impacts vehicles ranging from 2006-2010, Ford Explorer or Mercury Mountaineer with the 4.0L SOHC engine.

THE TRANSMISSIONS HAVE A PROBLEM AND HAVE HAD A PROBLEM FOR YEARS. THEY CAN FAIL WITHOUT NOTICE AND CAUSE A VEHICLE TO LOSE MOMENTUM WHILE GOING DOWN THE ROAD. YES THIS IS AN OLDER VEHICLE BUT IF YOU LOOK UP OLDER COMMENTS ON THIS VEHICLE ON OTHER REPORTING SITES THERE ARE MANY REPORTS OF TRANSMISSIONS CAUSING SERIOUS PROBLEMS. WHY HAS THIS NEVER BEEN DEALT WITH IN ANY MANNER? I WAS DRIVING DOWN THE HIGHWAY AND MY VEHICLE BEGAN TO SLOW DOWN AND WOULD NOT MOVE FORWARD. I WAS ABLE TO GET THE VEHICLE IN GEAR AND GET IT TO THE SHOP. I PAID TO REPLACE THE TRANSMISSION AND IT DID IT AGAIN IN THE NEW TRANSMISSION. I ALMOST DID NOT MAKE IT UP THE HILL NEAR MY HOME AND HAVE BEEN FORCED TO PARK THE…

DRIVING ON SPEED LIMIT I STOPPED AT A LIGHT, CAR ENGINE WENT DEAD. I TURNED KEY OFF AND WAITED A FEW MINUTES, TURNED KEY ON, CAR STARTED AS NOTHING WAS WRONG. IT HAS HAPPENED 3 TIMES IN THE PAST YEAR. BATTERY AND ALTERNATOR ARE PRETTY NEW. DECIDED TO TAKE TO AN AUTHORIZED MECHANIC DEALER, COULDN'T FIND ANYTHING WRONG WITH THE ENGINE. REALLY? WHAT IF I WAS DRIVING IN A HIGHWAY? CERTAINLY I WOULDN'T BE ALIVE TO REPORT IT!

THE UNIT HAS ISSUES WITH THE SEAT BELTS. I CALLED THE DEALER BUT THEY SAID THAT THEY DON'T HAVE ANY RECALL CAMPAIGN REGARDING THIS ISSUE, AND NO GUARANTY CAN BE APPLY.
