On average, the 2017 Ford Explorer starts to “feel” problems with the ENGINE and its various aspects after 13 552 miles.

Recently reported ENGINE problems on 2017 Ford Explorer

I rented the referenced vehicle from enterprise rental car for 1 week. drove approximately 2000 miles. this 2017 vehicle had approximately 20,000 miles on the odometer when i rented it. i believe that the engine was the 3.5 liter version. every time i accelerated hard, such as entering on the interstate, i could subsequently smell a very strong exhaust smell in the interior of the suv. i also noticed when i rented the vehicle that all the windows and surfaces had a film on them - perhaps residue from exhaust gases. i am a 54 year old retired engineer and have owned and rented over 25 vehicles in my lifetime and find what i experienced with the explorer to be very unusual. i also found that i was sleepier than normal when driving perhaps due to co2 exposure. all of my passengers also experienced unusual sleepiness. the exhaust smell in the interior was undeniable. i find it very disturbing that ford is trying to explain this as a problem with only the police interceptor explorers due to after market modifications. my experience indicates that this is a completely false and misleading explanation. i am very pleased to see that the nhtsa is doing an ea on the problem. ford has ignored this problem for years and the problem is very real. i was considering buying the explorer which was one reason i rented the vehicle and from my experience i will not touch this vehicle and will not be purchasing one. please do your due diligence regarding this problem and i hope to see that this eventually leads to a overall recall of all affected explorers. thank you.

Carbon monoxide detected in passenger cabin - after reading stories about possible problems with carbon monoxide (co) in 2016 ford explorers in mid july 2017 i purchased a kidde battery powered co detector and installed it in the rear area of the passenger compartment. it had not alarmed until we were traveling from seneca, sc to indianapolis, in. we were towing an 8x5 enclosed u-haul trailer at normal freeway speeds. tow/haul was engaged because we were towing and the engine was generally running at higher rpm's, especially going up the mountain inclines. the co detector first alarmed west of ashviille, nc. suddenly the headaches and drowsiness both my wife and i were experiencing made sense. we opened the windows and the alarm stopped after a couple minutes. after this happened 3-4 times i moved the detector to the front of the passenger cabin so that i could monitor the part per million display. we found that it only took 15-20 minutes of highway driving for the detector to display 31ppm, the detectors minimum concentration detection threshold. the level would then build over time. due to the detrimental effects of co on the human body i never let the concentration exceed 62ppm. i found, however, that the peak co concentration detected was 103ppm. i assume this was reached while the detector was in the rear of the cabin, where the display was not visible to me. the service manager at lake keowee ford suggested that i run the hvac in recirculate mode. i tried many different hvac modes - recirculate, normal/outside air, rear hvac turned off - but the result was always the same, co being detected in the cabin within 15-20 minutes. needless to say i am not buying ford's claim that this problem is only with law enforcement vehicles with body perforations from the installation of after market equipment. the vehicle is going into a carmel, in ford dealer this afternoon.

Tl* the contact owns a 2017 ford explorer. ever since the contact purchased the vehicle and began driving it, she experienced nausea, vomiting, dizziness, blurred vision, and headaches intermittently. the contact required hospitalization for the symptoms, but received no diagnosis. the contact stated that the symptoms occurred when she was in the vehicle for an extended period of time. the vehicle was not taken to a dealer or independent mechanic. the vehicle was not diagnosed or repaired. the manufacturer was not made aware of the failure. a dealer was not contacted. the approximate failure mileage was 300.

After a scary long drive from indiana to north carolina i took my vehicle to the local ford dealer service department letting them know that i could smell exhaust while driving and i felt overly tired, way more tired then need be. after testing it was determined that co was coming into the cabin of my vehicle. they still have my vehicle now after 2 weeks and the parts that were ordered were body filler and electrical tape. this does not seem to be the appropriate fix for this situation that could cause catastrophic injury or death and now i am scared to put my and my families lives in danger due to my vehicle trying to kill us. the vehicle was being driven on the interstate as speeds of 50-75 mph. this is very dangerous and if i would not have stopped so many times i would have passed out and caused an accident which could have killed me or someone else. i was advised that if i was going to drive the vehicle i should do so with the windows down, which is not acceptable and why i have had a loaner car for weeks.

Fumes enter car wile driving!

We purchased this vehicle brand new on 8/11/2017 (19 miles)and we started noticing a smell of exhaust when we accelerated and when we had the rear a/c on coming in the cabin. we had it at the dealership from sept 25, 2017 to oct 6,2017 (1496 miles). the problem still exists when we picked it up from the dealership on oct 6, 2017. we believe this is a serious health concern as we have been experiencing headaches, especially my wife, who is the primary driver. we will not let our grandchildren ride in this vehicle with the exhaust fumes present. we are aware that ford is aware of this problem since 2012. as this is a brand new vehicle,with 1496 miles, we feel that this problem is not going to go away anytime soon. we do not want have to keep taking this to the dealership for temporary fixes (tsb). we want a permanent fix, if that includes getting a new one.

Occasionally when i drove the car i felt light headedness and diziniess. on 8/3/2017 i felt the dizziness again and ended up in a car accident. i felt as though i was going to pass out and in a flash i crashed into the car in front of me.

My 2017 ford explorer xlt with base 3.5 v6 has been hard to start from the first week of ownership. it has less than 5000 miles on it now and isn't fixed. ford dealership stated it would have to get worse before they could fix it. vehicle shows no dtc's or any history! my wife has refused to drive it out of town due to the fear of it not starting at all. we have recorded over 30 videos of it not starting and have sent videos to ford motor co. with the same response, cant fix it if it isn't broke. apparently it will have to either break something internally and leave my wife and child stranded, before it will be diagnosed. it is a $40000 lemon that takes 3-4 times attempting to start before the engine will run. this weekend it took at least 30-40 seconds before vehicle started, then it would not idle correctly! still no dtc's! vehicle does this no matter the length of time engine has run or level of fuel? it does it during remote start or the push button. it does at times have a strong odor of gas after start-up, almost as if it was flooded? as a person in the automotive repair world, the absence of concern from ford is shocking! so instead of trying to correct a issue before it becomes a danger, they would rather it become dangerous and then repair it? if it is a fuel related issue, then this is a potential hazard that needs to be addressed. the vehicle is getting worse, but as said earlier, it will have to completely not start before something is done. ford motor co has not been very helpful, and now i am proud owner of vehicle that will not start correctly.

Carbon monoxide leaking through the ac vents

Exhaust smell comes into the cabin when car is accelerating. seems worst when the ac is in re-circulation mode. you can smell the exhaust fumes right after the engine/transmission has downshifted to accelerate.

I am concerned about my 2017 ford explorer and a carbon monoxide leak. i have overall feeling bad since we got our new 2017 ford explorer, which is very out of character for me. i am a prior special operation veteran, overall in good health, and only 30y/o. like many, who have complained about this vehicle i am getting nausea, weakness, and tension headaches from driving this vehicle. i have been very weak and having headaches, as of late. this has had a major impact on my day-to-day life. i couldn't explain why or what was going on with me it seemed as if it came out of nowhere. i am starting to think maybe i have long term exposure to carbon monoxide over the last 3 weeks. i got the ford explore 3 weeks ago and this sudden sickness has been happening since then. i got so worried with my health"i went to the doctor. i explained to the doctor "i have no clue what's going on with me but i feel absolutely horrible. i feel like i have had a flu for almost a month". i was desperate and i know i sounded crazy but i have been having some serious bouts with weakness, fatigue, and headaches. i went to the doctor on july 31st 2017 and i really have been baffled by the sudden onset of symptoms. this was before i knew about the nhtsa investigation into the 2017 ford explorer. i saw the story run today (8-3-17) on good morning america and i started to put two and two together. at the doctor's appointment on (7-31-17) they pulled blood, and are conducting a bunch of test but nothing has come back. i am concerned, i am hoping it's not related to the carbon monoxide leak that others are reporting. my biggest concern is for my pregnant wife and unborn child. as a purple heart vet i have put my heart and soul into our great country and i need this agency to please find answers to if these suvs are safe. my families could depend on it thank you for your service.

We purchased this vehicle march 2017. we have noticed that each time the vehicle requires rapid acceleration, for example passing another car on a two-lane road, you will smell exhaust fumes in the cabin of the vehicle. these fumes enter the cabin via the air conditioning vents and will be so strong that all occupants will develop difficulty breathing. during routine acceleration, we have not detected any fumes, however some occupants have developed headaches simultaneously intermittently.

The vehicle was tested and found to have 18 ppm of co in the interior while in operation.

Strong exhaust smell in passenger compartment when accelerating and/or merging into freeway traffic. i had to open all windows as my eyes were watering.

I was driving on the new jersey turnpike at 4:00 pm . i was traveling in the second travel lane at approx 68 mph surrounded by lots of traffic and many large semi trailer trucks. all of a sudden the car started beeping and when i looked at the dash board to see what was going on, it said" transmission is not in park" within seconds i lost all power. the screen went black and the engine had died . i had no power when i stepped on the gas pedal. as my car was slowing down i was able to make it to the breakdown lane safely before the car came to a stop. i had my daughter and young granddaughter in the car also. thank good we were not hit by any cars or trucks on the turnpike. after shifting to park when the car came to a stop, the dash said " step on the break to restart". luckily the car did start so that we were not stranded on the turnpike. this is a very serious safety issue and ford needs to address this immediately

I am an attorney filing this report on behalf of and at the request of my client, the vehicle's owner. the complaint is a noxious odor which fills the vehicle during its operation; after numerous repair attempts by ford, this concern has not been corrected. when driving the vehicle, the driver has observed the interior has become inundated with a noxious, overwhelming, and potentially dangerous odor of gasoline, exhaust and/or fumes. the driver has felt ill effects after this occurrence and is concerned about carbon monoxide poisoning or other health problems as a result. this issue is very concerning because of the potential health effects and because vehicle cannot be driven for any substantial period of time without filling with this odor. the issue has most often been observed with highway driving when the engine is under load, i.e. accelerating. the problem has been ongoing since shortly after the time of purchase of the vehicle. the first repair attempt by the dealer for this specific issue was made in july of 2017. at least 4 repair attempts have been made subsequently. the issue continues. this law firm has requested that ford take back the vehicle and refund the client's purchase price under arizona's motor vehicle warranties statute.

Explorer with 2.3l ecoboost produces an exhaust smell during moderate to wot throttle runs. generally seems to occur after lifting off the throttle and returning to cruising throttle position. vehicle must be vented to prevent illness to passengers, has happened multiple times. occurs more often when vehicle is under significant load (such as climbing a grade).

Strong exhaust smell in the entire cabin of the vehicle upon exceleration so much so you have to roll down the windows to evacuate the smell. it's an on going problem and just not a one time event. i have a four old daughter that sits in the 2nd row that i'm concerned about.

Exhaust fumes entering vehicle when stationary and in motion.

Strong exhaust odor in the cab of the vehicle. this usually occurs during acceleration and when the ac is on. the odor is so strong, we usually have to put the windows down for relief.

Exhaust smell coming into cabin from the front vents on highway acceleration.

On january 27th, 2017, my wife and i leased a new 2017 ford explorer. every time we operate the vehicle, we get extremely sick (some symptoms we experience are sore throat, running nose, headaches, and nausea that last hours after exiting the vehicle). this occurs about 10-15 minutes while driving/operating the vehicle. the heating system was set to 75 degrees fahrenheit and the windows were closed. after we felt sick we did shut off the heating system and open the windows but there was a slight odor in the cabin and we still feel several aliments. doctor appointments have been made for myself and my 6-month-old daughter that was in the vehicle (this being my most significant concern). ford motor corp installed a new exhaust system, removed the rear bumper and resealed any leaks, checked cabin pressure and tried to reseal any cracks that may allow exhaust to renter the cabin. ford stated that the vehicle was fixed, after being brought to them for the third time (they said they found more leaks and resealed them), but refused to give me any documentation stating that the vehicle is safe for my family and myself to be in. the vehicle has been in and out of service several times, a ford service technician located at sayville ford test drove the vehicle with me and confirmed the same ailments. the vehicle was picked up from service after ford stated it was fixed for a 3rd time and we were still getting sick when we drove the vehicle. we contacted ford again and we advised them of the situation for a 4th time and their response was 'by its very nature, new car smell is due to plastics and adhesives in the vehicle. it could be an irritant to some. unfortunately, you may have to consider other options that may be available to you.'

Family has been having neurological symptoms after smelling severe exhaust in the cab of our vehicle.

Tl* the contact owns a 2017 ford explorer. while driving at an unknown speed, carbon monoxide emitted through the vents in the vehicle. the driver became drowsy while driving. the carbon monoxide remained in the vehicle until the windows were rolled down. the carbon monoxide detector detected 13 ppm to 16 inside the vehicle. the vehicle was taken to lake elsinore ford (31500 auto center dr, lake elsinore, ca 92530, phone number: (951) 471-4100), but they could not detect the carbon monoxide due to not having a carbon monoxide detector. the manufacturer informed the contact that it was not an issue and someone would call back. the approximate failure mileage was 20,350.

While driving exhaust fumes enter cabin while excelerating and when air conditioner is on

While driving, usually during fast acceleration no matter the speed, there is the smell of exhaust in the cabin of the vehicle. i have already taken the vehicle to the dealership where i bought it and they say they couldn't find anything wrong. the smell of exhaust is present almost every time i drive the vehicle.

Smell of egg/sulfur in the cabin of the car after rapid acceleration. i had notified the dealership at my last oil change. they didn't seem concerned about it. the smells has continued. dealership is now telling me to wait till nov 1st. this has been happening since i bought the car in dec 2016 and has steadily gotten worse. i didn't think it was a big deal since the dealership didn't seem concerned.

I have a 2017 ford explorer platinum which i purchased brand new on november 25, 2016. it took me a while to realize but every time i would drive the explorer, my eyes would get very heavy and i would develop a headache. i commute 42 miles each way for work and i cant count how many times i almost fell completely asleep. after some research, i found out that this was a common problem to due to possible carbon monoxide (co) leaks entering the vehicle through the ventilation system. i immediately contacted my local ford dealership and had this looked at early this year. ford replaced the exhaust manifold and i noticed a major difference in how i felt when driving the vehicle. recently, in the past two weeks i have been experiencing the same issue again with headaches and feeling sleepy while driving. i have made several attempts to contact ford corporate about this and i have not received any response. i would like for them to either completely fix the issue or allow me to trade in my vehicle for another one. this is truly a hazard not only to myself but for my passengers (wife and kids) and to others on the road. please help to get this resolved...
