The 2006FORDEXPLORER carries 788 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 18 crashes, 8 fires, 17 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2006 EXPLORER is power train with 174 filings, followed by power train:automatic transmission (114) and engine and engine cooling:cooling system (75). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 4 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 13 investigation files overlapping the 2006 EXPLORER, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration. Use the related-complaint feed below to read raw owner narratives before deciding whether any pattern here affects your specific use case.

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 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] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

THIS TRANSMISSION SHOULD BE RECALLED!!!! THE REVERSE BAND BREAKS AND IS A KNOWN ISSUE FOR THIS TRANSMISSION!! NO WARNING JUST WENT TO REVERSE AND NOTHING! UPON RESEARCH THIS HAS BEEN A KNOWN ISSUE SINCE DAY ONE!!
Transmission
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 VEHICLE AS IT IS NOT SAFE TO DRIVE.

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!

I WAS TURNING FROM TURNING LANE INTO WAL-MART AND WHEN I GAVE IT GAS THE TRANSMISSION SLIPPED AND WOULDN'T MOVE. LUCKILY NO CARS WERE COMING AND IT FINALLY KICKED IN AND LET ME PULL INTO THE PARKING LOT. I JUST BOUGHT THIS AND WAS LOOKING UP THE ISSUE AND FOUND OUT THIS IS A PROBLEM WITH FORD EXPLORER 2002 - 2006. WHY ISN'T THERE A RECALL ON THESE TRANSMISSIONS? THIS IS VERY DANGEROUS!

I TOO HAD THE SAME PROBLEM AS I WAS COMING TO A FOUR WAY INTERSECTION. AS I WAS DRIVING ALL OF A SUDDEN A WRENCH TOOL CAME UP AND I COULD NOT ACCELERATE SO I HAD TO PULL OFF IN A PARKING LOT BEFORE I GOT TO THE INTERSECTION. I DID NOT WANT MY VEHICLE TO STALL AND I TURNED THE VEHICLE OFF AND PUT IT INTO NEUTRAL AND LET IT SIT THERE. I THEN TOOK IT OUT OF NEUTRAL AND STARTED IT BACK UP. I COULD FEEL THE JERKING AND FELT LIKE I GOT REAR ENDED IN THE BACK. MY HEAD JERKED FORWARD AS I WAS DRIVING WHILE IT KEPT JERKING.
