Within the first, original, 2000 miles of driving my new 2015 Ford Explorer my family and I have been subjected to an oder that is similar to melting plastic, burning hair or engine exhaust fumes in row passenger cabin while driving. This is especially noticeable after high RPM acceleration or during highway driving. In relation to this smell is are symptoms of headache, tiredness, and or nausea. I have brought vehicle to multiple Ford dealerships, the last time the dealership had the car for over 4 weeks! we have been told that necessary repairs have been made. But the vehicle and my family are still experiencing the same problems. Vehicle now has just over 23000 miles on it. Since buying vehicle I have had a number emergency room visits that were not conclusive and after reading findings by this Agency and others now believe that there is a connection to my Ford Explorer, and we are suffering from prolonged carbon monoxide poisoning!

There is a strong smell of what I could only at first describe as natural gas or propane (rotten eggs) entering the cabin. It was compounded when I put turned the cabin heat on. With winter upon us the smell enters the heating ducts making it nearly unbearable. Furthermore while driving under normal acceleration on a minor road there was an audible pop (as if a hose beneath the engine came off) and a fluttering noise with loss of power. I am assuming a turbo or waste gate hose came off on its own. Once the hose popped off the smell was undeniably singed motor oil. After 30 years of doing oil changes I can assure you it is the smell of burning motor oil. I have seen many such odor complaints on the 3.5 litre eco boost turbo. There is definitely a problem affecting many if not all turbo eco boost engines. Please investigate this dangerous noxious singed oil odor. I purchased this vehicle in May 2017 as a certified used car, it is currently in the dealership for repair. I am available to assist in any way to help with the investigation. I am an owner of a vehicle with the takata recall, this condition and nauseating smell is far far worse. Please help.

There is a bad exhaust smell inside the cabin of the vehicle. Mostly when the HVAC is on defrost. Upon inspection, there seems to be a cracked exhaust manifold. This smell happens the strongest when it's colder out, at idle, and while driving.

Purchased my vehicle in July 2017. Due to an unrelated power issue that occurred under full throttle, I had to drive my car on a lot of full throttle runs at highway speed to help the dealership diagnose the issue. This went on for weeks, trying to get the dealership to duplicate the problem. After they allegedly finally fixed the problem. I continued to drive my Explorer vigorously on the highway to make sure the power issue was corrected, (that issue is not my complaint as it appears to be fixed). However during all these weeks of frequently driving at high rpms, I had headaches almost every time I got to my destination. I seldom get headaches and certainly not almost daily. During certain times, depending on how long my trip was, I also smelled what seemed to be strong fumes, even when there were no vehicles nearby or in front of me. I recently learned that there were other Explorer owners having issues. To my shock, I saw that a lot of owners were stating that they were noticing the fumes when the car was driven hard, which is the kind of driving I had been doing when I noticed the fumes, and normally would not have. I have gotten to where I have to feather the pedal during driving to minimize the odor of fumes. I also have a pregnant wife who I won't allow in the vehicle anymore and surely will not be able to place my newborn child in this Explorer to be exposed to fumes of this amount. This is the most money I ever spent on a vehicle and I'm at a complete loss. I am very fearful of putting my family in this vehicle, especially a newborn.

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.

Ford Explorer carbon monoxide issue. The cabin of my 2015 Ford Explorer fills with carbon monoxide anytime I have the windows open and I accelerate. I have a co monitor in the car and can watch it as it goes up within seconds of acceleration. I have had the car into two different Ford dealers and had the current tsb performed as well as the latest reprogramming of the HVAC system which did reduce the co from inside the cabin while the windows are up, however as soon as a window is cracked the carbon monoxide levels rise. With any amount of acceleration they tend to range between 21- 33ppm in the cabin.

My 2015 Ford Explorer limited started having problems 2 days after pulling out of the dealer. They have not stopped. Unfortunately, I waited too long for a lemon law claim. Most important problem: The smell of exhaust in my cabin under heavy acceleration, since day 1. it has been in 10 times since August 2015. The exhaust has been taken apart multiple times 1."trans roll restrictor rubber hanging against exhaust pipe" was found. Replaced roll restrictor. Did something with tsb. 2. returned for same smell: Reprogram HVAC module, replaced left rear air extractor, applied seem sealer to areas in tsb. Replaced grille and valve assembly. 3. two months later, same thing - replaced grille and valve asy, reprogrammed HVAC module, replaced air extractor 4. one month later: Installed muffler asy; rvc code for tsb 1; replaced wheel lip molding, valve asy, dual rate air extractor still have the smell, but am always told they don't smell it. I had two people get sick and vomit in my truck because of the fumes in stop and go traffic. Additional problems: 1. rear running lights did not work - twice at dealer to get repaired 2. air bag light on constantly - wire assembly - tsb 16 was spliced 3. AWD off & ABS lights constantly on - cost me $582 for them to take everything apart and check "pin fit" at all terminals. At which point the codes went away. 4. driver-side outside door handle just broke off when I went to open the door - $149 5. when vehicle is put in park I get an error message vehicle not in park. I need a shift module, $395 plus tax and fees 6. multiple other small problems. Vents not staying open, plastic covers coming off everywhere, speaker replaced twice my Explorer has been in the shop more times than I can count and Ford does not give loaner cars. I've been without a car for days at a time.

I purchased a new 2015 Ford Explorer. Within a couple of months I noticed a smell in the car when accelerating or going up hills. I took it into the dealership and they confirmed there was a carbon monoxide leak and repaired it. The repair was not effective as the leak was still there. I took it in for a second repair from the released tbs but it still emits the cm in the cabin when the vehicle exceeds 3K rmps or the ac is on full blast.

- Meridian, ID, USA

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.

Exhaust smell in cabin after wide open throttle (wot) period onto highway. Exhaust smell in cabin in general during vehicle operation with heavy throttle. This is even after having the aformentioned repairs per Ford with the liftgate and rear seals area. See attached picture. I believe some of the leak may be due to lack of exhaust manifold bolts
