2017 Ford Explorer Sport. Consumer writes in regards to carbon monoxide leak issue.

- West Hollywood, CA, USA

Exhaust still entering cabin following Ford corrective measures. This vehicle has been serviced for this seemingly ongoing issue using the corrective measures specified on the most recent technical service bulletin (17no3); however, the carcinogens and carbon monoxide produced by the exhaust are still entering the cabin following acceleration. As with other serious complaints involving this vehicle, the odor is a delayed response to acceleration, but very evident. As NHTSA is the consumer's avenue for assistance in protecting their health and safety, this ongoing open investigation should result in creating provisions that demand this company take ethical measures in preventing toxic substances from entering their vehicles. The open NHTSA investigation has already concluded, "Ford has issued multiple tsbs related to the exhaust odor issue, and in some cases revised those documents multiple times...". if the manufacturer is continuously generating new technical bulletins, but complaints are still being raised with models as old as 2011, the end result is that the manufacturer is not taking these incidences seriously enough. Ford needs to be forced into correcting a disastrous design in their exhaust system as the technical service bulletins are obviously not producing results needed to protect consumers. Practices such as reprogramming the air handling system to allow for more "fresh air" to come into the cabin when accelerating is counterintuitive to preventing exhaust from entering the cabin. Measures to protect consumers from these toxins should be the only NHTSA conclusion. The fact that this has been ongoing since 2011, with no corrective change in the exhaust's design is also clear indicator that the manufacturer is not interested in taking this seriously. For now, rolling windows down during acceleration is the only measure to protect against these toxins.

Oil leak around turbo at exhaust. Could be related to the NHTSA vehicle safety recall # 16V925000 as the vehicle has the same 3.5L gtdi engine and seems to have been manufactured during the time frame of the 2017 Ford Explorer police interceptor vehicles effected.

Engine oil leaking between oil filter and filter adapter assy. The vehicle was taken to oc welch Ford on Dec. 28th 2018 for repair for first time. The filter then began to slow leak oil and the vehicle again was taken to oc welch Ford on Jan.18th 2019. The problem appears to be the adapter assy has either a hairline crack or was machined out of specs. Oc welch Ford ordered the adapter assy. Currently pending notification from the dealer when repair is complete.

I was traveling on a highway in the right lane at 55 mph, with tractor trailers to my left and behind me. I changed the radio station and a warning suddenly appeared on the dashboard stating "transmission not in park". I felt the car becoming sluggish and I lost power steering and power brakes. I was able to pull off the road, but had no turn signal to warn the truck behind me. He narrowly missed me as I pulled off. When I came to a stop I realized the car was turned off, as if I had hit the ignition switch. I put the car in park and switched on the ignition. I could not believe I had inadvertently turned the car off, but assumed I must have, while changing the radio. Yesterday, Jan 32, 2018, my vehicle lost a serpentine belt and I lost power. The tow truck driver asked if I saw a warning that said "transmission not in park" before I lost power. He said he had been hearing that from many Ford Explorer drivers lately - that their vehicle suddenly stops running, especially when they are using the radio. I will follow up with my local Ford dealer, but I believe this is a major safety concern, as I am now finding others reporting the same issue in online Ford forums.

Took Explorer to the dealership. For the rotten eggs smell for the second time as well as another issue. They did not address the exhaust smell and when question a second time they stated it was driven and the could not smell it. I was told to drive the Explorer until it got worse and then bring it back in. This is unacceptable. Ford is knowingly allowing dealerships to place defective Explorer back on the street. People are getting hurt with this exhaust problem. Something needs to be done since I need to drive it until it gets worse, or pass-out and wreck the Explorer

2017 Ford Explorer Sport AWD had the courtesy service for the exhaust bulletin done. I don't know what they fixed because the car still smells of exhaust when I accelerate hard. Trying to merge onto the highway on ramps comes to mind. Or if accelerate hard from a stop light in the city. Pretty much have to lower the windows. Dealers are useless they just claim the vehicles are safe. Have had this issue since purchased new.

As I was reversing I placed the vehicle from reverse to drive and it became very hard to turn the steering wheel. On several different ocassions the exhaust has blown smoke and the vehicle smells like fumes after turning it on.

Our first road trip in this vehicle was November 23, 2017. We drove about 300 miles South to galveston, tx. On the way back home, I was driving, when we got to about houston, I told my husband I needed to pull over and let him drive, as I didn't feel good and felt like I was going to pass out. He drove the rest of the way back home. I was thinking maybe I was getting sick or coming down with some kind of bug. I just felt always dizzy and light headed. I started to get a strange feeling my head, a strange tightness'I then got concerned. I went to my doctor on December 27 to find out what he thought it may be. I just felt so weird and funny. I continue to go throughout January and my doctor telling me I needed to get a mri on my brain because I couldn't shake whatever I had. The strange feeling of dizziness was always there. I took off many days from work as I would start to drive into work about an hour away and kept feeling so dizzy that I couldn't drive. I kept telling my doctor when I was in my car driving that I felt the worse. I thought perhaps it was some kind of motion type of sickness like vertigo. He tested me for many things like that and after my mri came back fine'I still was having issues. After many tests, medicines and all and never finding anything that would make it better, I didn't know what else to do. I just knew I had felt weird and dizzy since our road trip to galveston. I had never thought about carbon monoxide until a friend of mine and I was talking about this weird feeling I kept having. She told me that I needed to take my car into the dealership and have it tested. Myself and my family have been smelling a smell every time I would drive. I took my car in May 8th, 2018 to the dealership and guess what'..it has a Ford customer service program 17N03 on the carbon monoxide! they say they want to fix the issue that really isn't an issue?!

Vehicle stalls when driving and is more pronounced when making turns. After stalling it starts bucking and I have to press gas pedal to the floor to get a response.

Ford Explorer exhaust---- we continue to have nausea, dizziness, headaches and at times extreme sleepiness. A few months ago Ford sent us a safety notice, stating they would reprogram the air conditioner. They stated this would fix exhaust gases entering the vehicle. This re-programing has not fixed the problem. We continue to have exhaust smells in the vehicle, especially on acceleration. We continue to have nausea, dizziness, headaches, sleepiness, and sometimes periods of confusion.

Family has been having neurological symptoms after smelling severe exhaust in the cab of our vehicle.

My Explorer Sport with turbo has a recurring oil leak that the dealership has attempted to repair a few times. I can smell oil burning within minutes of driving the vehicle and there are oil stains on our garage floor. My concern is that oil may be leaking onto hot engine components creating a fire hazard. The dealership has had the vehicle for over 2 weeks cumulatively and I believe this is part of a bigger problem. The GM told me today that he believes this is a freak occurrence, but in speaking with a friend of mine whose husband is a mechanic on Ford, he said the Ford knows this is an issue, but hasn't issued a recall for this model, yet. I'm not sure what to do at this point. I just know that I'm paying for a vehicle that I can't drive and the dealership doesn't know how to repair it which is very concerning.
