Loss of power: While driving my 2015 Ford Explorer XLT with 3.5L V-6 engine on the highway (10/04/18), the wrench light came on and the car started to shudder and lose speed. Pushing down on the accelerator had no affect and the car rapidly decelerated. The engine was running very rough with heavy vibration. This was a terrifying and nearly fatal experience as faster moving traffic started passing me on both sides as I tried to move off the highway. I was able to move the car to the side of the highway and limped off the nearest exit. Once off the exit I shut the car off and sat for 20 minutes while I re-gained my composure and called my husband. When he arrived he started the Explorer and the wrench light was cleared. My husband drive the car home using only back roads while I followed in his car. We called our local Ford dealer and scheduled an appointment. We started researching this issue and found this to be a well known problem with the throttle body on Ford's V6 engines which are used on multiple SUV's, crossovers and sedans. The research I've seen shows this issue has affected more than 10,000 owners. However, it's not clear if the throttle body is faulty due to a manufacturing or design defect. It's also not clear if replacing the throttle body is a permanent fix. I'm terrified to drive the car on the highway and since this happened we've only used it for shorter trips around town. The Ford dealer checked the car today (10/08/18) but since the wrench light was cleared they found nothing wrong. I pleaded with the service advisor to no avail. We've been a Ford family for more than 15 years but this fault and even worse the Ford service advisor's response is completely unacceptable. This is a serious and dangerous problem and only a matter of time before someone and their family are killed. Please investigate and force Ford to issue a recall.

I was driving on the interstate at 70 mph and I heard a loud clunk and my engine lost acceleration. I could not increase my speed and the car would not go. I had to pull off the road and the car was running rough and when I pushed on the accelerator pedal the car barely moved. I was almost rear end by a truck but luckily I was able to pull over safely. The wrench icon came on my dash and said to take to dealer. When I got home I took it to the Ford dealer and they did a diagnostic test and it showed a P2111 fault code. The throttle body was faulty and had to be replaced. This malfunction put me in a very dangerous position.

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.

2015 Ford Explorer Sport exhaust in the cabin I began smelling raw exhaust when I would first start my car, the air blowing though my vents. I would roll my windows down because it made me immediately nauseous, as I drove the smell would go away and roll my windows back up. The smell only went away for a few minutes as the cabin resaturated with exhaust smell. I started troubleshooting and found when I turned on recirculation while driving the smell subsided. This only worked while driving and using less than half throttle. I would smell a rotten egg smell when I would use part to full throttle anywhere I was traveling. I contacted my dealer and they performed the exhaust complaint repair. After driving the car the last few days from getting it back there has been no difference. As the weather heats up I am using air conditioning more and have been starting to get headaches, nauseous and lose of energy. My coworker rode with me today and complained within the first minute of driving that exhaust smell was present in the car and was getting a headache. I rolled down the windows and have not used the climate control. I will not be using the climate control until this is fixed, I do not want to be another victim of a serious injury accident or death.

Cabin is filling with extremely intense smell of carbon monoxide. It is impossible to drive as you can not stay in it for more than a few minutes. It doesn't matter if your just driving around town (5-10 miles per hour) or if you try to go on a highway (40-60 mph). It just gets worse. After a brief time you get lightheaded and nauseated. I had the vehicle to a Ford dealer a few months ago to supposedly fix the problem. Whatever they did certainly didn't work as it has now gotten to this point.

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.
