Whenever you accelerate quickly or put the engine under strain (such as going up a hill) and the air conditioning is on and recycle mode is engaged you get a strong exhaust odor into the cabin. The vehicle has been back to the dealership to fix this problem but the fix has not worked.

The seal around my windshield flaps when it is warm outside. It causes a horribly loud noise/vibration.

Exhaust fumes enter cabin thru air vents when the car is in heavy acceleration and air is on recirculate.

Along with many other Explorer owners I am having an issue with smells in my 2016 Explorer. When accelerating I get the occasional rotten egg/sulfur smell coming from the vents. I also get on occasion a smell of burnt exhaust in the car when idling or parked for a short period of time. I also get a strong antifreeze smell after driving for a while (no visible leaks). The dealership had the car for an entire day and (as usual) could not duplicate the problems. Ford needs to admit they have a problem that is widespread and it needs to be figured out now. This is my first Ford since 1993 and I'm not very pleased with my purchase.

Exhaust fumes while in motion - egg smell like- burned hair - mostly when accelerating I have noticed since w purchased dealer had me change all of the fillters going in for a second try on April 25th

- Miami, FL, USA

Exhaust fumes fill the cabin when accelerating and rpms are above 3000. It is worse in the back of the vehicle. One Ford dealership has already told me they cant fix the problem after multiple attempts. Ford Motor Company has now told me I need to take it to another dealership and see if they can fix the issue. The issue first appeared after the vehicle had about 13-15K miles and is still an ongoing issue at 20K miles.

There is an exhaust smell that comes into the vehicle sometimes. I have 2 children and do not want them getting sick from it. It started when I bought the vehicle new. I emailed the salesman and he said its probably just the motor because it was a new vehicle and once I got more mile on it the smell would fade. It did get better but it still does it.

On Monday, March 13, 2017, while in my son's driveway (20225 woodbine, detroit, mi 48219);I started the ignition and just as the engine leveled out, the rear lift gate glass "exploded." No foreign objects were found in or around the vehicle. Being parked between two homes, I found it odd that such an event would occur. I took my vehicle to bill brown Ford for repair, and advise them of the situation. Once I was home, I contacted Ford Motor Company, and spoke with a person named "maggie, " who gave me a reference number (cas11880598) and said that the dealership would do an investigation as to what occurred. On March 15, 2017, I picked up my vehicle. However, prior to leaving I advised mary of the body shop that Ford issued me the above reference number, and that they (dealership) would do an investigation as to what happen. On Monday, March 20, 2017, bill brown Ford stated that the Ford Motor Company would not reimburse my expenditure and considered the matter closed. I have read that this has happen before on the 2016 models. I would hate for this to happen on any other window on my vehicle while in operation on any public roadway. I was fortunate it happen in a driveway. Please view this matter as a "safety concern."

Strong exhaust fume smell in cabin after short, rapid, acceleration or when the car drives up an incline.

- Broomfield, CO, USA

Recently while traveling on the highway we experienced the smell of exhaust inside the vehicle. The windows were closed, ac was on and recirculating inside the vehicle. There were no other vehicles around us when we smelled the exhaust fumes. Also, my wife has complained of feeling nauseous while riding in this vehicle. We have not taken vehicle yet to the Ford dealer but based on what we have read about the Explorer, this is happening to a lot of people and Ford is unable to rectify the issue.

I purchased a new 2016 Ford Explorer Sport. I have had the vehicle for about a year now. We have had repeatedly noticed a gas / exhaust odor in the vehicle cabin. It's seems to be coming from the vents and becomes stronger when in idle or on an incline. I have twice taken the vehicle to a Ford dealership service center and both times had it dismissed and was told they could not smell the odor. The first time I left the vehicle with them for the day and the second time I drove over when the odor was clearly present but results were the same. However guests in my vehicle and other non- Ford technicians have been able to smell the odor. I feel this is a safety concern for this vehicle and needs to be addressed.

Noticed a month after purchase of new car, cabin filled up with gas smell entering freeway. Spoke to car salesman.(had just filled car with gas & w/capless system I connected the dots, thought that's why it happened & spoke to salesman. Then next time I had to rev the engine to accelerate/pass, it happened with 1/4 tank gas. Sent a ps to salesman 11/29/16 thru email. He said it takes the car 3K-5K mi. To break in. I just tried not to get on freeway, only drove it around town. We used my hubby's truck for freeway. This weekend, went to nephew's bb game on 2 lane 42 mile rd. Had to pass slow car in front of me--car had such a gas smell, I got a sore throat from it and had to roll down windows to breathe. I was shocked it happened again. Looked up on internet what I could find and was horrified at the pgs. And pgs. Of comments regarding this issue and class action lawsuit as well for 2011-2015's. I have a new 2016 with 4200 mi. My heart aches for all these hundreds of families with sm. Kids while co and carcinogenic gases are coming thru the vents and no one is doing anything about it. I saved for a long time to buy this vehicle. My ex and I have bought 10 Ford's. I'm devastated that this expensive car (for me) is slowly killing me. Look at the classaction.org, tons of comments. Look at carproblemszoo.com, tons of comments. They had so many they needed a part 1 and part 2. if you go to 2016 Ford owner comments, they are there too. I downloaded approx. 50 pages of owners' comments with the same prob. The vast majority had no resolution. I'm so sad. Somebody needs to take care of these problems. I don't understand why there hasn't been a recall. Someone is dropping the ball. I guy started to pass out while he was driving but managed to pull over. Service mgr. Called-- scheduling my car tomorrow-6 pgs. Of tsb to go thru. We'll see.

While driving at 30 mph on a city street a carbon monoxide detector that I have placed in the third row sounded. I installed the detector after learning that Ford was having problems with the Explorer. I opened my windows, parked, and checked the detector which was working. I returned home and called the Ford dealer and scheduled an appointment for next Tuesday morning.

- Santa Fe, NM, USA

Carbon monoxide leaking into the car cabin: The car was being driven at 75mph on a highway, climate in the car 71 degrees, and recirculating air was on. Car was driven for about 2-3 minutes before carbon monoxide detector started sensing carbon monoxide. Digital carbon monoxide detector alarm sounded when it hit 35ppm, then the levels climbed all the way to 49 ppm. No smell was present at the time of the test. No cars surrounding the vehicle. At this time, when levels hit 49ppm the windows were rolled down for fresh air to gain safety for the driver. We were able to document video and images of this event. Ford field service engineer states to his knowledge the 2016 Explorer has been redesigned and the concern had only been documented on the earlier models.

- Rancho Santa Margarita, CA, USA

Exhaust/odor in cabin. After vehicle is warm, not necessarily at high rate of excelleration or speed. Concentration is high enough for headache, watery eyes and urgency to seek fresh air. Odor is very noticeable from the exterior as well during episode.

Carbon monoxide: I have been smelling an exhaust like smell in my car since I purchased it brand new. For awhile, I assumed it was new car chemicals burning off from the engine etc. However, over time I still was presented with this odor. My husband and I bought a carbon monoxide detector to see if any dangerous fumes were presenting inside the car. Upon my quick 6-7 minute drive to church the carbon monoxide levels read 6ppm. When driven later by my husband for about 15 minutes at a slightly faster speed, it climbed to 12ppm! we had the air conditioner on and the recirculating air on. When we held the carbon monoxide detector up to the air conditioner, the numbers climbed faster. I have a photo of the 6ppm, but my husband didn't have his phone and couldn't take a picture of the 12ppm at the time. He will try to get a one soon. This car is the primary vehicle for my three and one year old children. We will no longer be using this vehicle risking their safety.

While driving the car on the freeway and under acelleration there is a horrible exhaust smell that makes my kids and myself nautious. It also gives me constant headaches. I didn't realize what was happening until my husband got in the car for the first time and noticed the exhaust smell

- Canyon Country, CA, USA

Exhaust smell when running the rear air conditioning system. Seems to occur when at higher rates of speed, 60+ mph with RPM 3K+. exhaust smell is isolated to the rear ac system when recycled air is turned on. The last test we did was on a highway, going uphill.

- Costa Mesa, CA, USA

I already submitted one complaint today about the cabin filling with exhaust fumes while accelerating but then I was reading other issues people were having and wanted to ensure you were aware of mine as well. I had to have the cooling fans replaced because they would come to a screeching halt when you would shut the motor off. I had to have the inside of the power lift gate repainted where the motor and shock are located because the paint was cracking. The center caps on the wheels are falling in so those are going to be replaced. It is now rusting on the back of my car by the rear tail light. The hood vibrates really bad when going over 65 mph. I haven't taken it in for that yet because I can't get it to do it all of the time. It has to be windy for it to happen to me. The front door black trim pieces on the outside started to bubble so those had to be replaced. The only safety concern is the hood vibrating. The rest are just fyi's as they seem to be common problems. I bought this car brand new in November 2015 and it has had problems since the 1st month.
