After a hard acceleration, on the highway or when accelerating on a freeway entrance ramp, we smelled a burnt hair odor in the passenger compartment of our 2015 ford explorer. after smelling this, i did some research and found other ford explorer owners with the same complaint and the smell was accompanied with carbon monxide. 9-28-15 dealership sealed rear underbody. 5-2-16 dealership installed new downturned muffler assembly. after this fix the smell went from a few seconds to a minute plus. caused watering eyes, headache and coughing. 7-26-2016 dealership replaced the muffler system that had "bad welds", and reprogrammed electronic modules. sept. 3, 2016 left on a trip, and the smell came back while paasssing on the freeway. also on a trip, the burnt hair smell came into the vehicle through second row, passengers, lowered window. the smell appeared again while going up a hill on freeway, this time through the drivers lowered window. watering eye, headaches and coughing accompanied the odor. 10-3-2016 dealership resealed all of the back of the vehicle and improved tailgate gasket. district engineer did an onsite inspection. 11-30-2016 picked the repaired vehicle up. 12-4-2016 exhaust fumes again while accelerating up freeway on ramp. 12-9-2016 ford denied a buy back claim. the odor never happens around town. i need to get rid of this 2015 ford explorer for one we can take on the highway.

During harder than normal acceleration, there is a very powerful sulfur (rotten egg smell) that fills the cabin. the smell id so powerful that you cannot stay more than 10 mins in the car without being sick

Have taken this vehicle to ford 4 times without resolution. exhaust smell overpowering during acceleration and now afraid to take long trips over inclined ed grades, essentially limiting to no towing, no visits to family, essentially a big white elephant in my garage

Carbon monoxide comes through the a/c vents when i hit 50/55 mph.

On acceleration getting exhaust fumes in cabin ( bad fumes ) talked to dealer and was told accelerate slow great words for problem have found this is not a new problem with the explorer is anything being done on this issue.

We own a 2015 ford explorer that we bought new. since we bought it it has been serviced at the dealership and we have had them look at it many times. i finally convinced them to do a repair on it after i told them about a tech bulletin. they kept it a few days and done something to it (not sure what) and told us it was repaired. we resumed driving it and since the repair we have told them we can still smell the same thing as before. the dealership has looked at it many times since then and has also drove it and continue to tell us they can't smell it and nothing is wrong. now my wife and i can smell it everytime we cross over the mountains to go to town and have told them that you have put this vehicle under a load to get it to smell. they still continue to say they have done everything we have asked and they can't smell. now that i have researched this issue i'm now concerned about the health of my family driving and riding in this explorer. someone please help all of those who are having this issue before someone get hurt or killed. the dealership has documents concerning this issue on our vehicle and i have documentation on it as well. however i do not have it scanned into my computer to send to you. if you need a copy of this please contact me and i will mail it to you.

Since purchased brand new in 2015, we noticed when accelerating that there was an exhaust smell inside the cab with the windows closed. we also noticed on long trips we would get headaches and feel sleepy/weak. called the dealer and complained about exhaust odor, and was told it would be 600-700 dollars to reseal the cab and do some other repairs. i feel this is not fair and this is a defect the vehicle had since new.

A follow up on a co problem, that happened on 7/7/15. dealer took the explorer in on the co issue along with ford knowing of it. gave us a rental for a week, and came up with no co levels after a week. went to the dealership to take a ride with the service manager, exhaust was present but he said it was a hot engine smell. no levels where found but symptoms in my body of co where indicated while the service manager was in the vehicle. left the vehicle for the day and was told by ford the service manager found nothing wrong and to come get the vehicle. upon the ride home my co detector indicated levels at 534ppm. with the windows down and the sun roof open at 70mph. along the way i stopped in the local hospital, waited an hour in a half for blood work then walked out. had to get back to work. only 15 minutes back home the levels went up to 871ppm. calling the dealership and ford in the am to get this problem solved asap before some dies. 2015 with only 4,500 miles. ford has known of this problem since 2011. updated 12/05/17*cn

Exhaust smell enters cabin under hard acceleration

In april 2015, we purchased a 2015 ford explorer 3.5 liter ecoboost v-6. from the first drive on the interstate going home with our new car. we had an exhaust smell on the inside of the car. every time we accelerate to go up hills of north east georgia entering the interstate, or passing cars, we smell exhaust fumes and have to roll down our windows to be able to breath. we have gone to the dealer, a "super store" , and they said that it is only the new burning off the engine. something needs to be done to fix this problem! we have an extended warranty on this vehicle and spending the extra money, these problems should be fixed immediately! these fumes could cause a health problem internally. please fix these problems...

Tl* the contact owns a 2015 ford explorer. the contact stated that while driving at various speeds, there would be an exhaust odor coming into the vehicle. the vehicle was taken to the dealer for diagnosis, where the technician stated that the exhaust odor was normal. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 10.

The exhaust leaking into the car it terrible, it's giving me headaches and making me feel sick. it has been going on since i purchased the car in 2015 but i can't take it anymore. the problem occurs when excelerating at any speed. taking off from a stop light or entering a highway.

Exhaust gas fumes come into the inside cabin while driving, mostly from the rear of the vehicle. the air conditioning or heater is on and the recirculation fan can be either on or off. failure mode can be on flat surface but mostly occurs going up and down hills. not sure if the decelleration of the vehicle is part of the cause. problem is intermittent, may not occur for weeks and then might occur 3-4 times in a day one specific example is on november 30, 2015, at 2:30 pm hvac system is set to heat, set to 73 degrees heat in dual temp control is on, recirculation is on, elevation is 3100 feet, going uphill on catron blvd towards highway 16 in rapid city, sd,(outskirts of town), decelerated from 50 to 40 mph at 40mph speed limit sign, several vehicles around us, odometer reading was 5482.5 miles, and smelled exhaust fumes in the cabin that appeared to come from the rear of the cabin, had to open both front windows for about a minute to get the smell out.

Occasional exhaust/sulfur smell inside vehicle cabin during highway acceleration or under heavy load such as towing trailer.. first noticed in 05/2017 and continues to the present day. initial complaint to dealer who indicated it was normal 'new' engine smell that would disappear over time and later conversations indicated 'unable to duplicate', plus i found later that apparently there was no documentation in the vehicle service records regarding any complaints.

Vehicle cabin is filled with a rotten egg/sulfur smell upon acceleration with the air conditioning running. the heating/ac system is normally in the "auto" mode. not noticed much in the winter because i live in michigan, but the rest of the year it is noticed every time i pass a vehicle or enter the freeway. had it to the dealer and my concern was verified, but i was told there is no fix yet. seems they are waiting for a recall. i have real concerns about my health and the health of those that ride with me. i sent a complaint to ford and received a "thank you", thats all. i hope you can move them into some type of action for a fix to this situation. thank you for your time.

This is my 2nd updated complaint on carbon monoxide entering our vehicle. after ford denying that carbon monoxide is not entering the civilian ford explorers, we purchased a pyle (pcmm05) low level carbon monoxide detector. it registers carbon monoxide levels starting at o ppm. we put the detector in our vehicle, started it and did not move the vehicle and the detector immediately jumped to 5. after that we drove the vehicle in city traffic and the detector then jumped back and forth from 10 to 14 ppm. after that we got on the interstate and drove 70 to 75 and the detector ranged from 23ppm to 64ppm in only a 30 minute period. we spent a total of only 2 hours in our suv doing this testing. after that we returned home and were sick with headaches, nausea, vomitting, chest pains, and just feeling sick for 6 days. we are currently not driving the vehicle because of all of these issues that we have proven with our own carbon monoxide detector. so if ford thinks there is nothing wrong with our vehicle, please buy it back and put your family in. ford you should be ashamed of what you are doing to hard working people that are having to pay and drive these rolling gas chambers. you need to be held accountable and i know we are not the only ones that feel this way. do any of your ford executives drive explores with the same problems? you should have to drive them and experience all of the sickness! do you not have any regard for your customers? quit lying and denying thetruth! and stay off the tv giving false statements about carbon monoxide not being in civilian ford explorers! we all know that is not true! hopefully ford will do the right thing with all of this and be responsible for their inferior product. quit wasting time and do it. someone do something, we are paying for something we can't even use or be safe in.

Since we took possession of our 2015 ford explorer we have had it in to the dealership more than any other vehicle we have ever owned. the smell from exhaust is horrible. in just over a year of ownership we have had it in to the dealership for this problem numerous times and is still as bad if not worse than when we started smelling it. they tried everything that ford told them to do and then they (the dealership) tried fixes on their own out of their own pocket and they still can not fix this problem. we smell exhaust fumes fill up the entire vehicle not only accelerating but driving just normally sometimes and it gets so bad that we have had to open all the windows and even pull the vehicle over and open all the doors just to air out our vehicle. we contacted ford directly one time about this problem and they told us that they were unaware of any exhaust problems regarding the 2015 ford explorer and as far as they were concerned there was no problem. it is about to go back to the dealership again for this very problem and the dealership is on our side as they have smelled it numerous times themselves and they still can not fix it despite going over the entire vehicle numerous times. we have 3 children and all we want is a safe vehicle and ford can not give that to us. we are very disappointed with ford over this whole thing.

Tl* the contact owns a 2015 ford explorer. while driving at an unknown speed, an abnormal odor emitted inside the vehicle through the ventilation system. the vehicle was taken to the dealer where the technician informed the contact that the ventilation cabins needed to be resealed and the vents needed to be cleaned. the vehicle was repaired. the manufacturer was notified of the failure. the failure mileage was 10,000.

Tl* the contact owns a 2015 ford explorer. while driving various speeds, the contact applied the accelerator pedal with force and smelled an exhaust odor. the vehicle was taken to the dealer (bill utter ford located at 4901 s interstate 35 e, denton, tx 76210; (940) 321-7400) where it was diagnosed and repaired. the repair specifics were not available. the failure recurred several other times. the manufacturer was contacted at 800-392-3673 and stated that there was no issue. the failure mileage was 24,000.

I purchased a brand new 2015 ford explorer xlt, 3.5 v6, in november 2014. at approximately 7,000 miles (beginning in april 2015) i started to notice a rotten egg odor inside the vehicle during acceleration, while entering the freeway. the smell would occur especially during a hard acceleration. the smell was noticeable while the a/c system was on "vent" and "recirculate" mode. on 7/6/2015 i took the explorer to my ford dealership and they acknowledged the complaint and stated there was a service bulletin 14-130 to correct the problem. their description on the fix, was that a special air-filter located inside the rear bumper area needed to be replace. they stated that the smell is coming from my evap-canister. i left the explorer there for the repair and it took them almost two days. they said, it was at least a full days labor to fix the problem because they had to remove the whole rear bumper and other parts, etc. after the repair was made, a week later, i was able to take the explorer on the freeway and still noticed the rotten egg odor during acceleration. this time the odor is only noticeable during "vent" mode when the a/c is turned on. i am contacting my dealer today about this. i am very concerned about this issue with other ford owners because these "fumes" in the cabin area most likely are affecting your health and other passengers. updated 12/06/2017*cn

Tl* the contact owns a 2015 ford explorer. the contact stated that there was an abnormal odor in the vehicle while driving approximately 45-65 mph. the failure happened without warning. the failure recurred on multiple occasions. the vehicle was taken to the dealer where it was diagnosed that there were approximately 20 holes that needed to be resealed. prior to the failure, the vehicle was taken to the dealer where it was diagnosed that the ventilation cabin needed to be resealed. the vehicle was repaired; however, the failure recurred. the manufacturer was not notified of the failure. the failure mileage was approximately 1,000. updated 08/30/16*lj; updated 5/9/18*jb *cn

Driving home up a hill with a newly purchased 2015 ford explorer my wife and i noticed a bad smell like exhaust fumes; we put this down to the new engine/exhaust burning off any factory grease etc. subsequent trips with all of my family in the suv we all experienced a foul exhaust and sulfur smell when going up a hill or accelerating above 3k rpm; there were no other vehicles in front of us to blame for the odor. we have taken the suv to the dealer 4 times now and they in conjuction with ford technical support cannot find the root cause. they have replaced/ installed: egr valve cover (tech bulletin), both exhaust down pipes, front transfer case. the dealer has no test equipment to find the problem or confirm we are smelling engine exhaust containing toxic gases including co.

I purchased the 2015 ford explorer in late march 2015. although the smell was there from the beginning it was progressively getting worse. it seems to happen whenever it feels like it. it occurs with the a/c off, while driving at a steady speed, and upon acceleration. i have taken it to brandon ford for several attempts to fix the problem, which they had no idea it even existed. after several attempts to fix the exhaust/carbon monoxide ford is telling me they have a report that a field engineer has deemed the fumes/poison entering the cab "a normal occurrence" and they will no longer put it in service. *tr

I have noticed this smell some since i purchased the vehicle, but it has progressively gotten worse. upon heavy acceleration (such as merging onto the highway), there is a very strong burning smell that takes over the inside of the vehicle. the smell seems to be exhaust coming into the vehicle. i have noticed an increase in "sleepy driving", or getting sleepy even if it is just on my way home from work. in july 2016 i took the vehicle in to be fixed, however, the fix did not work. this morning i took it back to the dealership for more repairs. i have a young child, and these fumes coming into the vehicle is not acceptable and needs to be taken care of immediately. ford needs to do something, or provide a major discount towards a new version that doesn't have this defect. i finally got the vehicle i wanted, and i can't drive it because of this issue. please make ford fix this problem. 7 years of this being an issue with ford vehicles is way to long!!!

You can smell the exhaust inside the cabin while driving. it is noticeable when you have to hit the gas to speed up to go around a vehicle or getting onto the interstate. after hearing on the news about the police having the same issue, i wanted to make sure that my complaint has been noted. i will be purchasing a co2 detector and placing it inside my vehicle where my 3 year old and 7 month old sit. there safety is top priority and hope a recall is coming soon. i noticed the smell when i purchased the vehicle new in march of 2015

I have noticed since the car was purchased new a strong odor coming from the air conditioning system when you depress the accelerator to max when passing a car or entering an on ramp. i have tried with both the fresh air on and recirculate on, the same effect is noticed. finally after dealing with this for about a year i brought it up to my dealer when the vehicle was in for its routine service. the service advisor informed me he has a 2016 explorer with the same problem and that ford came back with something about vents not opening quick enough at the rear of the vehicle. to his knowledge, there was no fix from ford as of yet. the smell does get quite strong and routinely the windows need to be lowered to prevent the strong odors from lingering. i am concerned as to what the odor is, possibly harmful emissions that could affect myself and my passengers? under normal driving conditions the smelled will appear when the accelerator is depressed more than half way, far too often in my opinion. i did notice more of the smell during the warmer months of the year and not as much when it was cooler/cold (we live in florida so never freezing).

We have also encountered exhaust fumes in the vehicle. on long trips we have also experienced fatigue dizziness and nausea. when we go on the trips we have a sheltie which comes with us, and he has not looked good at times also. so on a trip today 7-7-2015 we brought along a co detector, on the way down for the hr trip the level was @ 81. that's with the ac on with temps outside @ 82. on the way back from are hr trip with temps still in the 80's the co level was @ 183. if you look at the cpsc.gov website you can see that @ the levels of 150-220 it will cause disorientation / unconsciousness & death!!!!!!!!!!!! so @ this point in our lives in our 50's we do not want to die. we will be asking ford to take our explore xlt limited back before we die. it only has 4200 k on it. i'm only hoping ford will take this matter seriously.we will be contacting ford tomorrow 7-8-2015 to file a formal complaint to address this problem, so others don' t have to deal with the co.

Tl* the contact owns a 2015 ford explorer. while driving and accelerating the vehicle, an exhaust odor entered the vehicle. the vehicle was taken to a dealer where it was diagnosed that the hvac module and air extractor needed to be replaced. the vehicle was repaired; however, the failure recurred. the manufacturer was not notified of the failure. the approximate failure mileage was 19,200. the vin was not provided.

I just have become aware the growing concern about ford explorer exhaust/rotten egg smell. my 2015 experiences this condition on a daily basis. i have asked the ford dealerships on numerous occasions to look into this but they have always told me "no problem found". my son came home tonight and told us a neighbor having the same complaints and now that i have researched it on the internet it appears to be a wide spread problem. it does get so bad that i have to roll windows down because of headaches.

Tl* the contact owns a 2015 ford explorer. while operating the vehicle, exhaust fumes were present inside the vehicle and caused the occupants to become drowsy. while using a carbon monoxide detector, the reading indicated that the carbon monoxide levels reached 60 parts per million. the contact indicated that the failure was most noticeable when the air conditioner unit was operated or while driving up an incline. the vehicle was taken to the dealer on several different occasions and the extractor, molding, valve asy auto drain, power take off asy, and the transfer case were replaced; but, the failure continued. the manufacturer was notified of the failures. the failure mileage was 100. the vin was not available. ..updated 09/20/16 *bf..updated 12/20/16 *bf *tr

Under hard acceleration there is an exhaust smell inside the cabin. dealer claims that this does not happen and no one else has complained about the smell. dealer is wrong there is a smell when accelerating full throttle.

During moderate to heavy acceleration, sulfur-like exhaust fumes enter the cabin through the a/c vents causing an unbearable smell. tsbs have been performed, including a new exhaust system, with no positive results. problem still exists. i am convinced it is directly associated with a/c control unit and the 3.5l engine. eco-boosts do not produce the smell. i even asked a police officer about his unit, and no complaints. they drive eco-boost engines.

Tl* the contact owns a 2015 ford explorer. during acceleration, an exhaust odor emitted from the vehicle without warning. the vehicle was taken to the dealer where it was diagnosed that the air outer vent assembly and valve assembly auto drain needed to be replaced. the vehicle was repaired; however, the failure recurred. the vehicle was taken back to the dealer where the technician stated that the vehicle was unable to be remedied. the contact was also advised to refrain from using the rear vents and hard acceleration. the manufacturer was notified of the failures. the failure mileage was 26,482. updated 09/29/16*lj *cn

2015 ford explorer -- smelling exhaust odors inside the car when accelerating over 3,000rpm, usually when merging thru interstate highways or expressways, driving over 75mph or going uphill. it happens with the a/c mode in "recirculation" or not. i bought the car brand new on july 2014. i reported the issue at least four (4) to six (6) with the dealership's service department, and they attempted with the help of ford engineers to fix it with instructions from tsb 14-0130 but it doesn't seem to help. on two (2) separate occasions, they had to give me a rental car for two (2) weeks because they were troubleshooting and attempting to fix it. i have also attached a letter from the dealership stating their interest in purchasing the car but i don't know if it has something to do with the defects but i find it very interesting.

I can smell gas fumes in the interior of the car when driving. sometimes the odor is more when i accelerate. the smell isn't there all the time, but is pretty strong when it is present. this has happened several times -- ever since we bought the car. we bought the car in 2014.

Leased vehicle new on october 18, 2014. problem began immediately at approximately 200 miles. when passing another vehicle or accelerating from stop, exhaust fumes fill the cabin through the a/c vents. occurs to the extent that all windows and sunroof must be opened in order to clear fumes. has made driver and passenger(s) light-headed, upper respiratory irritation has happened, as well. generally occurs when windows are up and a/c is operating. reported to dealer, was told "there is no tsb for this problem based on your vin" (though all prior year explorers 2011-2014 have this problem and it has not yet been resolved by ford, and there is a class action suit in fl which was given class action standing by a judge in october, 2014. my vehicle is not "yet" lemon law eligible because the number of repair attempts has been limited by health problems. ford should offer to buy effected vehicles back without need to go through lemon law, as this is a carbon monoxide and "breathing exhaust fumes" health hazard which occurs almost every time the vehicle is driven.

Smell of exhaust fumes and/or sulfur-type odors coming through air conditioning system under heavy acceleration, passing on highway, or when engine is under a load. fumes/smell get so bad that i have to roll down all windows and open sunroof to ventilate the passenger compartment. tolerated the headaches, nausea, and light-headedness while driving until situation became intolerable and had begun to avoid driving the explorer. first serviced in 10/2015, dealer had vehicle for 4 or 5 days. i was told that a tsb was performed which included removing the rear bumper and using sealant, but that did not correct the problem. fumes in passenger compartment persisted. on 9/26/2016 took vehicle back to dealer for further diagnostics and repair attempts for same problem. dealer had vehicle through 10/4/16, and called to tell me to come pick-up vehicle as it was "fixed" by cleaning a/c evaporator, and also "speaking with ford engineers". went for test drive with service manager. after approx. 4-5 miles on highway, under varying acceleration conditions, cabin began to smell like fumes again, coming through the a/c vents. then i began to feel light-headed and informed service manager of same. could not ventillate vehicle due to heavy rains, but taking a/c off of "recirculate air" helped only a little, and changed nature of odor slightly. dealership was using a meter to measure what was supposed to be carbon monoxide. was consistently told throughout that measurements were "low" at 900ppm to max 1500ppm. when driving with same meter, it alarmed multiple times, but i was told it was because meter responds to breathing in the car. i determined that meter was for carbon dioxide not carbon monoxide. returned vehicle to service, was told ford is having regional rep examine vehicle on 10/11/16. i have filed a lemon law complaint with bbb.

Purchased a brand new 2015 ford explorer. almost immediately began smelling exhaust fumes. concerned that this wasn't "new car break-in", i purchased a carbon monoxide detector with memory. over a couple of weeks of driving the detector registered 97 ppm at peak. after checking on the internet, i found others that have had a similar problem. *tr
