Started noticing smell of rotten eggs this past summer while driving, dealership said it was probably just sealant used around windshield getting overheated. Always had headaches after driving even for 15 minutes at a time. Smell went away this winter but headaches and funny feeling after driving have still been a concern. Now am learning it has something to do with exhaust leaking into rear of vehicle.

I have noticed a distinct exhaust smell within the cabin of my 2013 Ford Explorer while driving. It has gotten increasingly worse over the past few months. At first, I though it was coming from vehicles in front of me, therefore I changed the heating or A/C to circulation mode but the smell did not go away. I noticed it happening even when I was the only one on the road with no vehicles near me. My 10 year old son and I have both been experiencing nausea and headaches when riding in the vehicle for more than a few minutes and I feel that I have finally narrowed it down to the exhaust fumes inside the car. My son complains of feeling sick almost every time we drive any distance in the car. I assumed it was car sickness but I too am experiencing the same problems along with headaches and dizziness. I have had to consistently roll down the windows in the dead of winter just to try to get rid of the exhaust smell in the car. I feel that this is definitely a safety concern and I no longer feel safe for myself or any of my passengers to travel more than a few miles. This happens when the car is in motion, stationary or idling and with and without the heat and A/C in use. The dealer can find no holes or damage to my exhaust system. There are currently no recalls on this problem but while searching for similar complaints for this problem online, I am overwhelmed with the amount of information from other Explorer owners experiencing the same problem. This is dangerous and needs to be resolved before someone loses their life or they or their children are hospitalized from carbon monoxide poisoning from the poisonous cabin air.

The exhaust smell in cabin of vehicle is unbearable. We have had our car in for repair of this problem 4 times and once before the fix. They had our car for over a month after the last "fix" was sent out. When driving the car with the air on recirc and you go into passing gear the cabin fills with exhaust smell. This problem is ongoing so for the "when did this happen?" below the answer is always. Since June of 2012 we have had this issue and is still present to this date,

Car has sulfur smell when using air conditioning. I have had my car for 2 years and have complained about problem and apparently I am not the only one.

When under heavy acceleration which is rare or when climbing any incline which is quite often where I live, the car has a horrible smell inside. Its worse when you have the heat on it seems. I have replaced the cabin air filter but it nearly seams worse now.

When my car is in park and running, it fills with exhaust fumes

- Hannacroix, NY, USA

We experience noxious fumes in the cabin when either the heater or air conditioner are on. It smells like exhaust or industrial chemicals or rotten eggs (hard to describe). Our local Ford dealership claimed it came from a leaking water pump (which they replaced under warranty) that saturated the under engine cover due to a leaking water pump. Driving in the winter actually requires we crack several windows and sometimes only use the butt warmers as it's too toxic smelling. The local dealership even acknowledged the smell, but again attributed to the leaking coolant. It's particularly worse when the system is in the recirculating mode. Sitting idle at a light or waiting for someone with the system on is probably the worst, particularly when in recirculating mode.

Air system, exhaust. I have been complaining to my dealership for over a year about the horrible air that is coming into my car when we use the A/C or heater. We have resorted to not using it because we can't stand the smell. I get my car serviced regularly at the Ford dealership where I bought it. They state since there is no recall there is nothing they can do to fix it. It is anytime the air is turned on and specifically the air for the back passengers.

There is an exhaust smell (like burnt hair) inside the cabin when the car accelerates, especially a hard acceleration and often when the air conditioning is on. Certified dealer cannot identify cause of issue or how it occurs.

Exhaust coming into the cab while accelerating.

- Mccordsville, IN, USA

The car has rotten egg bad/smell inside the car since the early of the car ownership. We brought to car to the dealer 2 years ago trying to figure it out the source of the smell, but was told it was due to the mildew. Currently, the car still have rotten egg smell coming from the air outlet. The smell is strong when it is idling. I am worry about the safety of my family.

When accelerating we get a very strong sulfur smell in the cabin. Most of the time it is so strong that we have to roll down the windows.

- Owasso, OK, USA

When accelerating rapidly a strong exhaust odor enters the cabin of the vehicle. Odor results in headache and at times nausea. However, odor is not as prominent if the car accelerates gradually only if accelerating quickly ie...merging onto the highway. This has been a problem since I purchased my vehicle May 10, 2012. I have inquired about this issue multiple times when the vehicle has been in to the purchasing dealer for service and was told each time that "no problem could be found or duplicated".

Carbon monoxide smell is coming out of vents when A/C is used. It usually starts happening after the car is warmed up. The smell is so strong I often have to turn off air conditioning and roll down the windows to allow the air to be cleared out. Often get headaches from this smell.

- San Clemente, CA, USA

During heavy acceleration... for example when I'm entering a highway... really strong smell of engine fumes enter the cabin... every time. I have a 2013 Ford Explorer XLT - very happy with my Ford otherwise.

- Zionsville, PA, USA

There is carbon monoxide in the cabin while stationary and in motion.

- Reno, NV, USA

I have 2013 Explorer Sport.. I have exhaust fumes entering the cabin through the vents(HVAC). Well know issues that seems to have no resolve according to Ford. Although they did issue a service bulletin back in 2014. From what I have read it doesn't seem to solve the problem. Many people still have fumes after the "fix".@$700-$850. Warranty does not cover the cost. A classs action law suit has been filed and awaiting for settlement decisions. Carbon monoxide is not something I want to expose my family to on a daily basis. Ford needs to find a fix or a recall need to happen. My dealer is cooperating and will be assessing the issue. But from what I read only one person has had a positive outcome from Ford. I hope this complaint will help push Ford to make a better effort to resolve this major issue.
