2006 Ford Explorer problems

“Hi, I purchased my 2006 ford explorer in 2019 from a mechanic lot. Since then I’ve 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 can’t 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 computer- however when a part is removed the computer is able to pick that up issuing out another code. Please assist Thank you, [XXX] [XXX]”

“TL* THE CONTACT OWNS A 2006 FORD EXPLORER. THE CONTACT STATED THAT THE RADIATOR WAS LEAKING FLUID. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 125,000.”

“The contact owns a 2006 Ford Explorer. The contact stated while driving at an undisclosed speed, the engine seized. The vehicle was driven to the shoulder of the road. The contact parked the vehicle and allowed the vehicle to set for a while. The vehicle was started. The contact stated that the vehicle was driven 100 yards before the failure reoccurred. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 150,000.”

“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.”

“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!”

“WITH ONLY 86,000 MILES OUR FORD EXPLORERS TRANSMISSION HAS FAILED ONCE AGAIN. WHEN WE HAD 23,000 MILES ON OUR VEHICLE WE NOTICED THE TRANSMISSION WAS SHIFTING RATHER HARD AND TOOK IT TO THE DEALER AND THEY FOUND NOTHING WRONG. AT 58,000 MILES THE TRANSMISSION ENGAGEMENT WAS SO ROUGH THAT WE HAD TO GET IT REPAIRED. SINCE THE WARRANTY IS ONLY UP TO 36,000 WE DECIDED OUR BEST BET IS TO NOT TAKE IT TO THE DEALER. WE HAD THE VALVE BODY REPAIRED AND IT RAN FINE UP UNTIL NOW. 86,000 MILES AND THIS VEHICLE IS ONCE AGAIN AT A REPAIR SHOP HAVING THE TRANSMISSION FULLY REBUILT. IN THE TIME I HAVE OWNED THIS VEHICLE I HAVE PAID OVER $7,000 TO KEEP IT RUNNING WITH REGULAR MAINTENANCE, TIRES, RADIATOR REPAIR, BRAKES AND NOW THE THIRD TRANSMISSION. *TR”
