7 Engine Exhaust System problem

Failure Date: 06/07/2021

Exhaust fumes inside interior-this seems to only occur on road trips where fast and hard acceleration is needed for highway driving which is not something we normally due. Since we have owned the vehicle, on every occasion of strong hard acceleration there is a strong exhaust / spent fuel smell being brought into the cars interior. We have reached out to the local Ford dealer several times but without satisfactory results. The exhaust fumes continue to exist in the cars interior upon hard and fast acceleration. My wife just returned from a interstate road trip with signs of exhaust fume poisoning with an extreme headache and very lethargic. What is it going to take for Ford to fix this problem or for a recall to be issued. Will it take fatalities or long term respiratory issues before anything is done to solace this issue. Besides the huge concern about the car owners safety and health; what about the potential diminished resale value of the vehicle due to Ford’s negligence to truly fix this exhaust issue.

8 Engine Exhaust System problem

Failure Date: 09/01/2020

While driving the 2015 Ford Explorer I can smell exhaust entering the cabin of the vehicle, especially under acceleration. I found this to be an issue in the 2016-2017 models,via a TSB 17-0044, but not the 2015. I am experiencing the same issue. I have contacted Ford and they seem unaware of the issue and requested that I take it in at my expense to diagnose and "possibly" find the issue on a per hour rate. I believe that this is causing my 6 year to get car sick, only in this vehicle, and my wife to feel tired and have body pains as she is the one who drives it the most.

Purchased the vehicle 4 March, was gone for 10 days. In the days since then, I have experienced exhaust smells in the vehicle multiple times, to the point that I have become light-headed. Usually, the smells only happen when the vehicle is relatively stationary (I. E. Stop sign, parked but engine still running immediately fter getting home, during acceleration from a stop, regardless of the setting on the hvac system. I'm attempting to return the vehicle at this time after researching multiple lawsuits against for for the faulty design. Due to the elusive nature of the problem, I can't provide photographic evidence. Also, on-going shipping problems in America (due to covid 19 problems) have led me to not being able to sources parts to prove there is also carbon monoxide in addition to the normal aroma of car exhaust.

18 Engine Exhaust System problem

Failure Date: 06/07/2018

2015 Ford Explorer sport exhaust in the cabin I began smelling raw exhaust when I would first start my car, the air blowing though my vents. I would roll my windows down because it made me immediately nauseous, as I drove the smell would go away and roll my windows back up. The smell only went away for a few minutes as the cabin resaturated with exhaust smell. I started troubleshooting and found when I turned on recirculation while driving the smell subsided. This only worked while driving and using less than half throttle. I would smell a rotten egg smell when I would use part to full throttle anywhere I was traveling. I contacted my dealer and they performed the exhaust complaint repair. After driving the car the last few days from getting it back there has been no difference. As the weather heats up I am using air conditioning more and have been starting to get headaches, nauseous and lose of energy. My coworker rode with me today and complained within the first minute of driving that exhaust smell was present in the car and was getting a headache. I rolled down the windows and have not used the climate control. I will not be using the climate control until this is fixed, I do not want to be another victim of a serious injury accident or death.

29 Engine Exhaust System problem

Failure Date: 08/02/2017

In June 2016, I took my Ford explore to gurley leep kia Ford in south bend indiana due to a rotten egg smell in the cabin area. They replace the exhaust system and sealed the rear telling me that exhaust was leaking into the cabinet area and that was the exclamation for the rotten egg smell. At that point I had only had my vehicle less than seven months. On August 2, 2017 we took my Ford Explorer back to gurley leep kia Ford and south bend indiana with the same complaints as well as the main driver myself experiencing nausea headaches trouble concentration vomiting and blurred vision. I have been attending college and working full-time with his required increased driving in myself being in the vehicle which would explain the intermittent headaches and nausea as well as the flareup of symptoms after being in my vehicle for approximately 4 1/2 hours. Diagnostic testing was done and it was confirmed that again exhaust was leaking into the cabin area the repairs were the same replace the exhaust and reseal the back, however this time they stated that Ford would not cover the cost of these repairs as it is no longer under Fords warranty and we were advised the cost of repairs would be near $3000. There are two TSB's out on this issue I feel that should've been covered by Ford at this point they should replace my vehicle it is been proven twice and documented that carbon monoxide/exhaust is leaking into the cabin area. I do have an extended warranty called route 66 they will not cover this as well. We also were advised that Ford Explorers are known for having a front strut mount issue both of mine we were advised were bad and it would cost approximately $500 to have a place to my knowledge there are no TSB's but the dealer seemed pretty aware of this and not surprised.

30 Engine Exhaust System problem

Failure Date: 08/01/2017

Exhaust fumes fill cabin under hard acceleration. It has happened many times over the past few years, we purchased car new in ~ may 2015. Typically we can limit by accelerating slower than desired, which can be unsafe when entering the highway. After hard acceleration has ended and you maintain steady speed the fumes no longer seem to enter the cabin. Fumes can be very strong and rolling down windows is the only way to clear. It seems to mostly happen with rear air conditioning in turned on, but not sure. I put todays date below, but this happens often. I have read online and spoken to dealers in the past and no fix seems to be available so we have done are best to avoid with slow acceleration, but we can not be certain that no fumes are entering car. Both my wife and I seem to get more head aches than in the past and this could be the cause.

31 Engine Exhaust System problem

Failure Date: 08/01/2017

32 Engine Exhaust System problem

Failure Date: 07/17/2017

I purchased the 2015 Ford Explorer used from a local dealership around July, 2016. My family noticed an odor (of exhaust fumes) in the cabin of the vehicle. It happened every time I accelerated quickly. More specifically, I was at a complete stop and then took off quickly to get onto a highway. I took the vehicle to the dealership from which I purchased it. They tested it and confirmed my complaint. They contacted the engineers at Ford to see how to fix the problem. I was told that my car was going to be a guinea pig. They replaced a seal and did something that required them to remove the rear end of the vehicle. The dealership did not charge me for the service. They also provided me with another vehicle to drive. When I got my vehicle back, I could still smell the odor. Again, I noticed it when I accelerated quickly. This time, I could smell it about 1 minute after the quick acceleration. During the acceleration, my air conditioning defaulted to an "off" position temporarily. I was concerned, so I brought the vehicle back to the same dealership. My car has been at the dealership for over a week this time. I have not gotten it back yet. They told me that they ordered a new exhaust system. I asked specifically if it was different from the previous one. They told me it was different. Again, they are not going to charge me for the repairs. I don't think the dealership should have to pay for the repairs either though. I think Ford should cover all repairs for this exhaust problem. To make matters worse, the Explorer they put me in while mine was in the shop had the same exhaust odor in the cabin. I reported it to the dealership, and they provided me a flex to drive. How can Ford expect their sales team to sell these vehicles knowing that there could be poisonous gasses going into their cabin?.
