Exhaust fume leaks into passenger cabin - problem since purchasing this vehicle new this spring; anytime when accelerating to merge into highway traffic with recirculating ac on a burning oil or acrid odor leaks into the cabin. In an attempt to fix the problem the local Ford dealer 'resealed" the undercarriage, however the problem persist. On a recent 400 mile road trip with recirculating ac on passenger and driver got very drowsy, windows had to be opened, recirculating ac turned off and stops made to shake off the effects. My previous 2013 Ford Explorer had the same exhaust problem but never like this. When I purchased this new model I took it on faith the "problem" wouldn't affect the 2017S. Ford has had a long time to figure this out and correct whatever manufacturing or design defect is causing this. I will contact the local dealer who has been very accommodating to advise I have filed this complaint. I just want a SUV that doesn't have this issue since 80% of my trips are 40+ miles of highway driving at higher speeds. All I want is a Ford Explorer that doesn't put my health at risk.

Since buying my Explorer I have noticed any time I accelerate I begin to notice an awful smell. If we do not roll windows down, everyone in the vehicle gets nauseous or dizzy. Today while accelerating on the interstate I had to quickly stop to throw up. It has never gotten to that point until today. After bringing it to nearest Ford dealership it was confirmed that it is a carbon monoxide leak and I would have to take it back to where I purchased it to have it repaired.

When driving vehicle I suffer from burning eyes, headache, nasea, feeling ill, vehicle was at dealer for CO2 leak, vehicle was out of service for approximately 60 days, I picked it up, drove home approximately 30 minutes and became ill, same as before it was supposedly repaired. I returned it to dealer the same day so they can try to figure why repair didn't correct the problem, I was told a district technician would need to come inspect the vehicle, this has been a problem since the first day we drove it home from the dealer. Vehicle has less than 3,000 miles on it. This repair was supposed to be the "recall repair" for CO2 leaking into vehicle, this repair did not resolve my issue, so not sure if Ford really has this figured out yet.

When accelerating past 2,500 rpms, exhaust comes into the car. It smells and has since I bought it. The dealership said it would burn off, I'm now at over 5,000 miles and it still does it. I keep telling the dealership. It is dangerous to myself and my daughter. Makes me light headed.

There is a burning smell/ strong odor of exhaust fumes entering the vehicle when driving. It seems to occur more often or become stronger when accelerating up hills or when accelerating onto the highway, but can occur when driving at any time. My wife, myself, family members and friends who have ridden in or driven the vehicle have smelled it. The smell can be stronger to passengers in the rear seating areas. This has occurred on numerous occasions since my wife has leased the vehicle on 01/20/17 and has been to the dealer twice to be checked, but they cannot find anything wrong. The vehicle will be returning to the dealer this week (09/06/17) again to be checked.

Exhaust smell comes into the cabin when car is accelerating. Seems worst when the ac is in re-circulation mode. You can smell the exhaust fumes right after the engine/transmission has downshifted to accelerate.

Gas odor leak inside the car while driving that caused me to have sxs of dizziness, nausea and vomiting. It happened in multiple occasions.

- Anaheim, CA, USA

We have taken our Explorer into a Ford dealership twice now. When you accelerate on the highway there is a really bad exhaust smell in the cabin from time to time. They claim to fix it every time and then the problem occurs again. I am very worried because I am 22 weeks pregnant now and I had been placed on bed rest due to spotting I was having. I am not sure if the two are linked. I am not on bed rest anymore. The car continues to have the same issue. This has been an ongoing issue. I will choose a date below, but it is ongoing.

C0 detector went off on a 3hr drive on 08-18-17 with ac and air recirculation on. After opening the windows the detector stopped beeping. The detector is a glui cigarette-lighter powered device w/ two usb ports (https://www.amazon.com/gp/product/B01G2yj3zu) and has been installed in the center console cigarette lighter (facing the second row seats) since mid May. No other time has this alarm went off. At the time of the alarm the detector was partially covered with some fabric from a bag and the detector was warm to the touch. We were camping in a place with no cell service so we did not get a chance to contact Ford/NHTSA. We drove home w/ the windows open. After coming back home I tried intentionally setting off the co alarm with a can of co. After warming up the detector by letting the car run I sprayed co into the detector but I was unable to get the alarm to go off again. It is unclear to me whether this was a false alarm from the detector or a legitimate issue with C0 emissions in the vehicle. There are not many active co alarms on amazon for cars, the glui one is the most reasonable one I've found. Any advice would be appreciated; I'll be contacting Ford today as well.

When I accelerate with the air conditioning unit on, the smell of exhaust is entering my cabin. I have to roll down the windows to let the smell out. According to the dealership, there is nothing wrong with our vehicle. I am concerned about my safety and that of my children when inhaling this smell.

My 2017 Ford Explorer XLT has exhaust smell coming through the vents throughout the vehicle. This is not a new car smell but rather exhaust odor and only is apparent when the ac system or fan system is in the on position. I purchased this vehicle on June 13, 2017 and was hospitalized on July 1, 2017 for three days. The doctors were unable to provide a diagnosis although I was experiencing headaches, dizziness and trouble with my vision. Every time I drive my Explorer and turn the ac or fans on I notice a exhaust odor. I develop a headache, dizziness feel sick. I called Ford and they told me that there is no recall on my vehicle and to take it to a dealer for a possible carbon monoxide leak or other issue that maybe causing the problem. Ford also stated that the problems were only on the police interceptor vehicles even though all exploreres come off same production line. Note: I have had this vehicle for almost two months. The new car smell is gone and there is no odor with the vehicle's engine is not in the on position. The toxic odor is only noticeable when the vents/ac/fans are running.
