When accelerating vehicle with the ac on, and in internal air mode, there is a smell like burnt rubber, or fumes that fill the entire car. I have to avoid accelerating too fast, or turn off the ac before hand to prevent fumes from entering car. This has been happening since I purchased the car in 2013. I thought it was just cause it was new, but as it's still happening, and others are having this same problem, I am reporting it.

When the Explorer is stopped or in park with the engine on and the heat on you can smell a sulfur/rotten egg smell inside the cabin. Looks to be a exhaust leak. I know this issue is already being investigated and have read up about the technical bulletins related to this issue and most reviews come back to say the bulletins did not fix the issue. This is a serious problem concerning the safety and health of my family of not knowing what kind of gas we are breathing in. Could be carbon monoxide or something else. A recall needs to happen for these vehicles.

I bought my 2014 Ford Explorer in November of 2015. I noticed a rotten egg/ exhaust smell as the weather became warmer. Anytime I would accelerate up a hill or accelerate on a flat stretch of road during the summer months was when the smell is the worst. I have to roll down all of the windows. I no longer allow my children to ride in the third row because they would complain on the longer car rides of having a headache. I have taken this to the dealership on 3 occasions now. They have told me they have tried to reproduce my complaint, and have failed to do so. I am currently going to that the service manager on a ride tomorrow to reproduce this smell. The smell has been so bad at times that I personally have felt like I was going to be sick. There is something seriously wrong with the Explorer having this smell. Something needs to be done. I am at the point that I do not put my kids in my car anymore then I have to. I have had to apologize on several occasions to my friends about the smell. Ford needs to figure this out!!

When the vehicle is accelerated, a very strong odor of exhaust comes from the air conditioner. I had a representative with me and they noticed the odor too. This happens no matter what road you are driving on.

In June 6/2016, my was was going 35mph, approaching an intersection when the wrench light followed by the "terrain management fault" warning came on. The vehicle lost all power. Traffic coming from her right received the green light and she was nearly killed by a driver who drove through the light, timing it for when it turned green. The vehicle spent 14.5 days at the palm bay Ford dealership in palm bay Florida were it was purchased new. Ford diagnosed the problem as a defective throttle body. I went online and saw the number of these throttle body failures and contacted the Ford customer service hotline. I explained to them I felt the vehicle was unsafe, that I had no confidence in the vehicle, and that if there had been no design change to the throttle body it would happen again. I was given a case number (which has now been closed), and notes of my concerns were made on the case. On 10/11/2016 I at 1530 edt, I was pulling out of a gas station turning right, with traffic approaching from my left. The wrench light came on followed by the "terrain management system fault" alert. The vehicle lost all power (throttle response) and the approaching traffic had to lock up their brakes to avoid a broadside collision!. I had my wife, 10yr old daughter and 12yr old son in the vehicle with me. Had a collision occurred my son would have been seriously injured. The vehicle went back to the palm bay Ford service department 10/12/2016 at 0900 edt. The throttle body had failed again as predicted, the vehicle is still there. I have contacted the Ford customer service hotline and received two case numbers now. 1: cas-10814941-Q8T7Z5, 2: cas-10830198. I tried to get Ford to take the car back and trade in on a new one as this is an "unsafe"vehicle. They will not help us and this throttle body issue is an epidemic! I am sure there has been lose of life from these "unsafe" vehicles?

Strong odor of exhaust fumes entering the cabin when accelerating. Very concerned with diver and passengers safety. This has been occurring since it was new. I took it to the dealer over a year ago and they performed a repair that did not resolve the issue. They then told me Ford was working on a fix and someone would contact me. I have yet to be contact and very concerned with constant exposure to the exhaust fumes. The need to take this seriously and give it a priority to fix this problem as I see there is a lot of people complaining of the same issue.

There is an overbearing almost intoxicating sulfur/rotten egg smell coming in the cabin of the car any time accelerating. I got this vehicle new in 2014 and it has been doing it since day one. At first I wrote it off as new car or possibly the turbo. But now after reading the thousands others with same problem I am extremely concerned for my family's well being. I have been driving my infant in this car for two years and I am very upset that I could have put her health at risk.

We have a 2014 Ford Explorer that has a smell inside while accelerating. We have taken it to the dealer to have the problem corrected. Our concern is that exhaust has been coming into the vehicle. We aren't sure if the current solutions in place to fix the vehicle are enough. Well knowing and our family is getting sick from this current issue we just aren't sure what we're breathing inside the vehicle is safe. The smell comes when you accelerate hard either towing or merging onto the highway or even from a red light. The smell is a sulfur smell or rotten egg smell that seems to dissipate quickly but is noticeable.

Exhaust smell in main cabin when rpms exceed 3200. Happens most commonly when climbing a steep grade or accelerating onto a freeway to merge with traffic. This has been occurring for past two years or so, it can smell like exhaust, burning hair, etc. Complaints to dealer are given a cursory explanation of excess fuel, it is normal and nothing can be done. I've owned many vehicles over the years and never experienced this. This happens every time there is a higher level of acceleration or rpms exceeding 3200.

- Phoenix, AZ, USA

I have frequently experienced a strong smell of exhaust and/or burning oil in the passenger compartment. This often occurs when the A/C is running and/or under heavy acceleration or climbing steep grades. I had mentioned this a few times to 2 local Ford dealerships and was advised by one that they are aware of possible issues involving a chemical or "propane" smell, but not exhaust fumes. The other had no knowledge that this was a frequent occurrence.

- Aurora, IL, USA

When accelerating to pass another vehicle, the cab of my vehicle fills with exhaust fumes. This vehicle has been brought to the dealership for service regarding this issue. The dealership was unable to solve the problem. They also claim that Ford does not know how to solve this problem. I was only told to keep checking back with them to see if a solution to this issue has become available.
