I may have already complained, but this can update that. When pulling a long grade and the vehicle has downshifted,3500 or more RPM and about 65 mph under load, I smell sulfur in the cabin. It seems to be worse when the covers for my moon roof and sun roof are retracted. It has been in to a dealer 4 times now, so I have lost a month of use. The last return was on Friday 1 July. I have not had a chance to take it to a local mountain that makes it smell. Ford keeps working on the back end, the exhaust there has almost no smell. I told the dealer the sulfur smell comes form exhaust that is escaping from the engine up to the back of the catalytic converters. There are two turbos on this vehicle and I believe two separate exhaust paths. Somewhere up front there is a leak that stinks. Thank you

The exhaust seems to be entering the cabin through the ac vents. We took this back to Ford as we bought it new and they stated at first it was just stickers burning off. Then I took it back again and made a manager to ride with me. He stated it was not normal and we left it there. They stated they replaced some parts a rerouted something. Seemed to be very confused on what they did. The smell never really went away and not that it has 20,000 miles seems to be getting worst. My wife is pregnant now and its her daily driver. I would just take it back and trade it in but I will lose so much in trade!! I just think this is very dangerous and I am worried for my wife and future baby.

Upon acceleration exhaust enters the vehicle cabin. Sometimes exhaust enters the vehicle cabin without acceleration. I thought I had reported this before.

My 2014 Ford Explorer was purchased off the show room floor with no test drive. My normal daily drive consist of 2 lane side roads. On the weekend my family and I will take the interstate routes. In early March as we began our trip and I accelerated onto the interstate there was a very heavy exhaust odor. The odor was thick enough that we had to lower each of our windows. We thought it was strange but perhaps just a one time occurrence but that wasn't the case. The problem is occurring during heavy acceleration only, with no air, with the air conditioning or with the heat on. I have taken my vehicle to Ford 3 times since August 2014 for a total of 26 days in the shop in hopes of getting this repaired with no luck. I did have a case open with Ford case# [xxx] and was told last week (11/13/14) by customer service person "[xxx]" that my case had been closed, reason; "the odor I am experiencing is normal" I was not notified by Ford that the case was being closed nor was the dealer where I purchased the vehicle. I placed a carbon monoxide detector in my vehicle and after 3 to 4 days on 11/01/14 received a warning to move to clean air! my vehicle is under full warranty however that is useless at this point. On 11/15/14 I had to take a 6 hour round trip with my mother, step father and mother-in-law we had to lower with window no less than 8 times during the travel and my mother had a very sick headache after the trip. This problem is real and I hope you will give it the time and attention needed to make sure other people like myself aren't just brushed off by Ford. Ford has my money paid in full for a vehicle I am forced to drive daily because I have no other transportation. And you ask do I also have headaches yes and they are very real.

I have experienced a burning smell entering the cabin area when accelerating to pass a vehicle and when climbing a hill. Also have had a "sour" smell like soured clothing from ac when I start my vehicle. I did ask a service manager about the "sour" smell and he said he never heard of it, not a big help.

During hard acceleration, a "smell" enters the interior of the car. The "smell" is of sulfur or rotten eggs. The smell is definitely coming from the exhaust. Ford acknowledged the problem and performed a tsb to fix. The tsb did not fix the problem, and the dealership says they have to wait for an engineer. Service manager says there is only 1 Ford engineer for all of South Texas.

Test drove brand new 2014 Explorer with 3.5L ecoboost turbo engine. Upon hard acceleration, the vehicle cabin experiences a strong exhaust smell that is irritating to the eyes and lungs. I decided against purchasing the vehicle for this reason.

I rented a nearly new Ford Explorer limited AWD in milwaukee, wi. I had been considering purchasing this model so I was pleased to be able to drive one for a few days. Every time I accelerated hard (wot) the cabin would fill with exhaust fumes. This occurred even with the ac in recirculate mode and without any other vehicles nearby that would have produced the odor. It was strong enough that we opened the windows to get fresh air. After the 2nd time of this occurring, I did not accelerate hard again as to avoid the problem. I also test drove a brand new 2014 ecoboost AWD model this weekend and it did the same thing. I will not be purchasing this model but wanted to add my experience to the database as I feel that Ford needs to fix this problem for owners of these vehicles. It is a shame, it was a nice vehicle otherwise.

When accelerating or doing freeway speeds the smell of exhaust circulates throughout the car. It is so bad that we have to roll down all the windows. This has caused drowsiness, headaches and our young granddaughter to have an asthma attack. The vehicle has been taken to 2 different dealerships numerous times and they both say that there is nothing wrong with the vehicle and that the smell is not abnormal. They claim that the car is not broken in yet and that the catalytic converter needs to burn off.

Bad odor in vehicle during acceleration. Smells like rotten eggs. This is a brand new auto. Very disappointed. Smelled it during test drive but salesman said that it was catalytic converter and the smell would go away. It has not.

Strong exhaust smell anytime engine accelerates, such as downshifting when going over an overpass on an interstate highway. Not "hard" acceleration really. I have researched, and know this a common problem, and has been since the "5th gen" Explorer came out. I know it has been brought to the attention of NHTSA, and I am just registering my complaint hoping you can get the problem resolved. Thank you.

Exhaust fumes enter the cabin through the A/C vents intermittently. The A/C controls must be turned on and the vehicle must be accelerating or climbing a hill. It loads the cabin heavily at times with exhaust fumes, but appears to clear quickly when normal operation resumes.

Was accelerating on the interstate and a very foul odor, like exhaust entered the cabin of the vehicle. This has happened on many occasions, with the windows up and down, ac off and on, heat off and on, going 10mph and going 60mph, during hard acceleration and during moderate acceleration.

Upon consistent moderate to heavy throttle, the cabin fills with fumes/odor which smells like a mix of exhaust and burning/smoldering plastic or epoxy. It is strong, easily repeatable and happens all the time while traveling up long consistent grades etc. Does not happen in easy city driving, merging onto an express way, it happens nearly 100% of the time.

Exhaust fumes enter the cabin area regularly when the sir conditioner is in re-circulation mode. This is a safety hazard for our baby who was born prematurely but has had to breathe in exhaust fumes when riding with us in our brand new Ford Explorer.

Explorer 6-cyl

  • 10,000 miles
The Explorer Sport (V6 twin turbo ecoboost) started leaking sulfurous smelling vehicle exhaust fumes (possibly cyanotic ) into the car which made the occupants feel unwell. Ford have a fix that they do not advise customers about so the fume issue is known to them ( tsb 12-12-4 ). this fix has been performed yet the odor persists in certain circumstances. We have little confidence that the problem has been properly resolved and we have little confidence in driving a car with this type of fault. It is disturbing that oxides of sulfur and hydrogen sulfide can only be smelled within certain concentration limits and that the "nose" becomes insensitive to them at higher concentrations. Other people are suffering the same problem and I think it S only a matter of time before a driver becomes incapacitated and has a serious accident. If this has not already happened. Many other reports of this problem on various websites.
