Vehicle: 2016 Ford Explorer 2wd v6-3. 5l VIN: [xxx] rchase: January 20, 2026 odometer at purchase: 70,929 miles (fraudulent — true mileage approximately 123,779 miles) dealer: drive time car sales company llc, dba drive time, 8805 e adamo dr, tampa, FL 33619-3525 narrative — copy and paste into NHTSA online form: on January 20, 2026, I purchased a 2016 Ford Explorer 2wd v6-3. 5l (VIN: [xxx] ) fr [xxx] sales company llc, located at 8805 e adamo dr, tampa, florida 33619-3525. At the time of sale, the vehicle had three open, unrepaired federal safety recalls: 1. Nhtsa recall 19v435 / Ford 19s17 — rear suspension toe link replacement (initiated June 26, 2019, affecting 1,194,173 vehicles). The rear suspension toe links may fracture, causing sudden loss of vehicle handling and risk of crash. 2. Nhtsa recall 21v537 / Ford 21s32 — rear suspension toe link cross-axis ball joint (owner notifications mailed March 2022, affecting 644,055 vehicles). The cross-axis ball joint may corrode and seize, causing toe link fracture and loss of steering control. 3. Nhtsa recall 25v347 / Ford 25s53 — b-pillar door trim detachment (owner notifications mailed June 2025, affecting 492,145 vehicles). B-pillar trim may detach while driving, creating a road hazard for other motorists. None of these recalls were repaired prior to sale. The dealer had documented actual knowledge of all three open recalls. Drive time provided me with copies of the recall notices as part of the purchase paperwork at the time of sale. Additionally, the recall documentation included a printout from the NHTSA recall lookup website for this specific VIN, timestamped January 19, 2026, at 5:28 pm — the day before the sale — proving that drive time actively investigated and confirmed the open recalls within hours of delivering the vehicle. Ford's own dealer notice for recall 19v435/19s17 states: "federal law requires dealers to complete this recall service before a new vehicle is information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2021 Ford Explorer. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The contact's husband, who was an independent mechanic, used a diagnostic machine to diagnose the vehicle and discovered a failure with the emissions system. The contact stated that the failure was like the failure listed in NHTSA campaign number: 25v455000 (fuel system, gasoline); however, the part to do the recall repair was not yet available. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000.

I own a 2020 Ford Explorer with approximately 85,776 miles. The vehicle has experienced two separate loss-of-propulsion events in traffic. On both occasions, the vehicle suddenly lost power while driving and stalled in the middle of a busy intersection. There was no prior warning of imminent engine failure. After stalling, the vehicle would crank but would not restart. The vehicle was disabled in the intersection for approximately 45 minutes to one hour each time. My family was inside the vehicle during these incidents. The vehicle displayed multiple malfunction warnings including “shift system fault” and messages indicating the vehicle was not in park even when the shifter was in the park position. The dealership, hansel Ford of petaluma, verified the concern and referenced Ford technical service bulletin (TSB) 23-2249 related to internal transmission components, including the valve body and park pawl actuator system. The dealership confirmed that when the vehicle is placed in park, it may actually remain in neutral. This creates an additional safety risk of unintended vehicle movement. This issue presents a serious safety hazard due •sudden loss of propulsion in traffic •vehicle disabled in active intersections •extended inability to restart •potential rollaway risk due to park malfunction the vehicle is currently pending major transmission-related repairs. I am submitting this complaint due to concerns about loss of propulsion and park system malfunction creating a safety risk for occupants and surrounding traffic.

The specific component or system has not fully failed. However, my vehicle is currently experiencing an intermittent check engine light condition, turning off and on, which was diagnosed at a retailer producing code p0018 then at the dealership and produced code p0017. The codes relate to the engine control module (ecm) detects that the camshaft on is out of sync with the crankshaft resulting in misaligned engine timing. I have requested that the dealership further review and escalate the diagnosis to determine whether the issue aligns with any known concerns, technical service bulletins, or manufacturer-supported programs. The vehicle and any related components are available for inspection upon request. At this time, the vehicle experiences reduced engine performance, including stalling, and inability to accelerator as needed, which pose a safety risk while driving, particularly in traffic or at highway speeds. The vehicle has been inspected and confirmed by the dealership. I have also contacted the manufacturer, who advised me to work directly with the dealership to have the issue reviewed and potentially escalated. I have since requested that they further evaluate the condition and determine whether it corresponds to any known issues or manufacturer-supported repair programs. At this time, the vehicle has not been inspected by police, insurance representatives, or other third parties. This check engine light and fluctuating rpm directly impacting the vehicles acceleration was the primary indicator of the issue. The manufacturer previously issued two customer satisfaction program notices to address this issue for other model year vehicles. I have attached both notices to this complaint. This demonstrates a manufacturer defect which is a safety hazard for drivers.

The contact owns a 2017 Ford Explorer. The contact stated that while driving at an undisclosed speed, there was smoke coming from underneath the hood with the check engine warning light illuminated. The vehicle was driven to the shoulder of the road, and the contact inspected the vehicle and became aware of smoke coming from underneath the vehicle. The failure reoccurred while the contact and the contact's minor children were traveling. A nearby police officer assisted the contact. The contact informed the officer that the vehicle was recently purchased from a carmax. The contact was advised to take the vehicle to the nearby carmax. The vehicle was taken to carmax, where the vehicle was diagnosed with engine failure. The contact was informed that the engine had severe fluid leaks. The vehicle was repaired. The vehicle was shipped back to the residence a month later. The failure reoccurred and was a persistent failure. The contact stated that the vehicle was taken back to carmax twelve times due to the failure. 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 86,000.

I was informed by the dealership that the engine issue with my 2021 Ford Explorer is the same issue for which a recall was issued. However, because my vehicle’s VIN was not included in the recall, I was required to pay for the engine replacement. I attempted to work with the dealership to have them coordinate with the manufacturer, but they declined to do so. I then contacted the manufacturer directly to file a complaint and request a review of the issue. I was advised that there was nothing they could do because my VIN is not listed under the recall. I am requesting that the manufacturer investigate this matter further and reimburse me for the repair costs if it is determined that the issue is applicable to my vehicle.

Smoke coming from engine bay area. Vehicle in limp mode. Mechanic says piston broke a hole in engine wall.

Front end axle actuator failing and causing all safety systems to turn off, loss of power and can lead to seized up front end.

While driving the crankcase sensor malfunctioned and caused my vehicle to stall without warning, this is a safety issue because of you are driving at highway speeds this will prevent the vehicle from being controlled properly to get to the side of the road. This sensor does not give any engine codes suggesting that it needs replaced until it goes out completely. The check engine light did not come on until after the component failed. I ordered a new part directly through Ford and even they said "yes that part will go out without any warning at all and will shut the engine down completely". When this sensor went out, it also caused pressure to build up in the engine which in turn has led to several other components that now need to be replaced. I have a had a mechanic look at it, and it now requires a turbo intake hose and a new turbo because the pressure that was built up in the engine due to the crankcase sensor going out burst the turbo intake hose and prevented the turbo from working correctly. It's approximately $4,000 in repairs due to a $150 part going out.

Description on your vehicle, some of the bolts used to attach the vehicle trailer tow hitch may have below-specification torque. Safety risk this condition may affect vehicle handling characteristics or lead to loss of attachment of the trailer hitch while towing, increasing the risk of a crash. Remedy parts are now available to repair your vehicle. Ford motor company Lincoln has authorized your dealer retailer to inspect and secure or replace the trailer tow hitch bolts as required free of charge. Next steps contact your dealer for more information to schedule the free service.

Leaking water pump that if isn’t repaired will cause catastrophic engine failure. Very expensive repair, $2800 because of internal placement of the pump. Since the water pump is in line with the crankshaft and located over the main body of the engine, it allows coolant to leak from the water pump into the oil pan. Mixed coolant and oil will lead to engine failure.

- I have experienced a sudden loss of engine power and speed on 5 occasions. Very scary and dangerous to completely lose power on the highway with cars behind you. Had to pull off onto the shoulder(s) in dangerous conditions, with two young kids in the backseat. Hazards, turn off the car, restart the car, etc. - when the power loss happens, the vehicle's dashboard lights turn on, including the engine and wrench icons along with the words "see manual. " - based on my research, I believe it may be due to a defective throttle body and/or software, related to the "terrain management system. " - problem was not reproduced or confirmed by a dealer or independent service center - no inspections by the manufacturer, police, insurance representatives or others - no warning message is provided prior to the failure, which is another issue.

The contact owns a 2015 Ford Explorer. The contact stated that on several occasions, while starting the vehicle and while driving at an undisclosed speed, there was an abnormally loud sound coming from the engine compartment. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the long block assembly had failed, and that the engine needed to be replaced. The vehicle was not repaired. The dealer was contacted. The vehicle was not diagnosed or repaired by the dealer. The manufacturer was not made aware of the failure. The failure mileage was not available.

My Explorer was very slow/unable to accelerate onto the highway. The next time I started it there was rattling and lots of non engine noises, along with all kinds of warning lights. I took it to the dealership. In his words ‘the turbo grenaded itself into the engine. Quoted me 15k to fix/replace the engine, turbo and half shaft. I still owe 9k on it. Extended warranty that I purchased expired 4,000 miles ago. I have had multiple issues with this vehicle since I purchased it brand new in 2020. I am trading it in tomorrow??.

There is an odor in the passenger cabin. Seems unsafe.

Police car started to run rough at low speed. Stalled in middle of road. Scanned codes and code for catalytic converter showed up along with misfires from numerous cylinders. Brought to dealer and was told needed plugs and a wire. Vehicle was returned and the same issue occurred. Fixed again. Picked up and once again the same issue started. Turned around and brought it back to dealer. The mechanic stated he never checked the catalytic converter as he was never told it had a code for the converter being bad. Two weeks later I am informed that cylinder 5 is bad. No compression. Two issues. Ford upped the warranty on the catalytic converters because of this common problem. The tech sheet shows that a bad cat will cause misfires, but never checked. Second issue is the recall 24s55 was for Fords with a 3. O liter engine, built in chicago, between the dates of 7/21 and 10/21. My vehicle was built in chicago on 9/21 and has a 3. 0 liter engine. I also received the post card regarding the recall and we had brought it t o the dealer. 24s55 states the valve could cause engine failure. Well now I have a bad engine. Ford says no recall even though prior chief brought to dealer after receiving postcard for recall.

The contact called on behalf of the owner of a 2019 Ford Explorer. The contact received notifications of NHTSA campaign numbers: 24v031000 (structure) and 26v101000 (suspension). The contact stated that after the vehicle was stopped at a traffic light, the vehicle stalled. The battery warning light was illuminated. The contact was able to restart the vehicle. The contact stated that the failure was occurring every other day. The vehicle was taken to an independent mechanic. The independent mechanic replaced the manifold absolute pressure (map) sensor and an unknown sensor; however, the failure persisted. The contact stated that on a separate occasion, while the vehicle was idling, the vehicle stalled. The vehicle was restarted. The contact stated that while the temperature gauge was midway, the vehicle stalled. The battery warning light was illuminated. The contact stated that whenever the temperature gauge was midway, the vehicle would stall. The vehicle was taken to another independent mechanic who replaced a fractured spark plug and the timing chain. The vehicle was repaired; however, two months after the last repair, the failure reoccurred. The manufacturer was not made aware of the failure. The failure mileage was approximately 130,000.

I was leaving the store pulled out on a main road in town about to head on the highway. My steering wheel locked and would hardly move with all my strength and the help of my significant other we pulled back into the store parking lot rarely missing hitting several vehicles in the process. I had my children with me at the time in this vehicle as well. The power steering assist fault message popped up. I had the vehicle towed to Ford groves and after a diagnostic test was ran I was told it was my steering gear and the entire steering column needed to be replaced. The second opinion I got said it was the rack and pinion needing to be replaced. After doing research I found other reports of other 2013 Ford Explorer owners having wrecks due to this some with the same edition as myself (limited). There are recalls for the steering on 2013 Ford Explorer but not the limited. I need my edition to be added because this is clearly happening here as well. This was very dangerous when I explained to the dealership about the recalls they told me this was not accurate and was the wrong information. This was random and happened out of no where my vehicle was fine prior to this. Yes the vehicle is available upon request for inspection.

My Explorer is only 4 years old and it suddenly suffered catastrophic engine failure due to low engine oil. The engine started knokcing and clattering before any warning lights came on the dash. This could also be due to premature bearing failure which is common in the 3. 0 ecboost engines.

12 v battery continues to die and I've had the car less than a year. On [xxx] the battery was dead. Our neighbor put it on his supercharger. On [xxx] the 12v battery low light came on while I was driving 30 miles away. It went off the next day and reappeared on Thursday [xxx] disappeared on Friday and back on Saturday. I called the future Ford on Monday and technician [xxx] said it only showed 15% charge. I took it in to the dealership and it was kept over night and the next day he said it was charged to 90%. I was not happy with the "you can come and get it". I told him I'm a [xxx] and bought this car so I wouldn't breakdown and now I don't feel safe with it. He checked the charge again while we were on the phone and he said it dropped to 80%. He said thats not good it will probably need a new battery. That evening he text and said it is fully charged and I can come get it without a new battery. I was not happy as I've received no reason for why it was losing charge. So I did some research on my on and text him back that evening. I told him about my research and found this was an ongoing problem and that they need to find out what is causing the draining issue. I'm sure the dealership had to know as there was a recall for this issue. I suggested a parasitic test, or software glitch issues to check. He said they would run the parasitic test. . He said it would take several days. I checked back on 12/4/25 and he said no progress today. I told him I want a copy of all the test run. Wouldn't you know it he gets right back to me saying a handful of modules need updated software. That they will attend them this morning. I think they were trying to get out of the fix as my warranty runs out this month. Why are only certain vehicles being recalled (mine not one of them), when they all should be recalled.

October 2025 check engine light came on, took to mechanic showed misfire in cylinder two and three. Replaced all plugs and coil packs, engine light went off. Engine light came back, hard start on November 26,2025 showed misfire in cylinder 2 and 3. Replaced those coil packs again, engine light off. February 2, 2026 engine light back on, hard start with vibration. Took vehicle to mtn view Ford in chattanooga to have diagnostic test done. Received call on February 9,2026 that the engine was in complete failure, coolant leaked into the cylinders, would require a $12,000 new engine at 84,328. 6 miles on the vehicle. The vehicle had not been driven more than 50 miles per week in the past two years, had on time maintenance.

Another timing chain failure on highway with engine stopping on road. This should be a recall!!!!! only 101,300 miles on engine. No warnings no check engine lights until after failure.

I was driving on a freeway when the engine stopped without warning. The timing chain apparently; slipped and the pistons collided with the alves leaving me stranded on the road. This si a dangerous situation that Ford knows of adn is ignoring. The car had 101000 miles on it. The car was serviced at 98500 miles by Ford but the timing issue was ignored by the mechanics becasue the computer produced no error codes. The obvious ticking of the engine was the only indication that there was a problem that the mechanics ignored. This is a know premature failure and danger to drivers and the engine should be recalled for repair at Ford's expense. Please issue a safety recall on this engine. ( 3. 5l v-shaped 3. 5l ti-vct) consumers are at risk for unexpected breakdowns without warning, at speed, in traffic. . .

Ford Explorer recall – ongoing safety hazard in July 2025, Ford issued a recall notice for my vehicle. Shortly after, the check engine light came on. Starting October 15, 2025, my vehicle began failing to start after refueling—making noise and taking multiple attempts to start. The same issue occurred repeatedly on October 23 and October 30, worsening each time. On November 3, we brought the car to a Ford dealership. They confirmed there is no available fix for the recall and said there’s “nothing they can do. ” I explained this was a safety issue since I drive my son with a disability to therapy daily. They told me I would have to pay out of pocket for repairs even though the problem is linked to the recall. On November 8, while driving in arizona, my vehicle again failed to start after refueling. Later that day, it lost power on the road, the speed dropped suddenly, and it would not accelerate. The same stalling and jerking occurred again on November 10 while my husband was driving. We contacted Ford corporate and NHTSA, but both said nothing could be done because the recall label says the car is “still drivable. ” this is inaccurate and dangerous. The car stalls and loses acceleration randomly, creating a serious risk of an accident. On November 21, the car again failed to start after refueling. This has happened multiple times each week, and Ford continues to delay a fix. My vehicle is unsafe to drive, and this unresolved recall poses an ongoing safety hazard to my family and others on the road.

When accelerating and braking, motor rocks forward and backwards. Rpms jump erratically when this happens and when sitting stationary at a light or stop sign. Which causes the entire vehicle to vibrate. Oddly enough, fuel injector cleaner seems to help with the vehicle shaking somewhat.
