Carbon monoxide leak. When I accelerate as I get into an expressway ramp, a strong odor comes into the car like rotten egg. Very concerning, specially since I took the car to a Ford dealer to get it fixed and is still an issue.

Beginning in February 2017, my 2016 Ford Explorer began to smell like sulfur or mold whenever I start the car. I suspected it was an ac coil issue, but there was no problems with this. I would like to submit my complaint as part of the ongoing exhaust investigation into the Ford Explorer carbon monoxide issue.

Loss of consciousness while driving the vehicle. I saw a news report that NHTSA was looking into the issue and it could be related. The vehicle was in motion with the A/C on and windows up while driving on a city street.

Exhaust smell in cabin upon hard acceleration or hill climbing. Problem occurs any time rpms exceed 3000-3500 for more than a few seconds. Wide open throttle is not required, just moderate engine strain in normal driving conditions. Exhaust smell seems to come through A/C vents and is worse with system on recirculate, but is definitely present when system is set to fresh air as well. Rear A/C system does not have to be on in order to get the smell. Exhaust smell is bad enough to burn your throat if not vented by rolling down windows quickly. Persons in back seat commonly complain of headaches when riding in the vehicle. Vehicle has been to the dealer a total of 5 times for repairs. None have corrected the issue. Tsbs 14-0130 has been performed, mufflers have been replaced, HVAC module has been updated, but problem still persists as bad or worse than ever. Vehicle was purchased brand new. Problem began around 1,500 miles. There have been no after-market modifications to the vehicle.

Carbon monoxide and gasoline smell in cabin

- Mansfield, OH, USA

I believe C0 is leaking into my car and while driving I have become dizzy and get headaches on a regular basis. I also become quite tired. I drive for a living and did not understand what was happening. This usually happens while driving on the highway with my windows closed. I never drive with my windows open but need to open them to get rid of the dizzy and tired feeling.

Exhaust fumes enter the interior of the vehicle upon acceleration. The dealer states that there is no part to rectify this problem. I am suffering with chronic headaches. Please help!! my next step is to install a carbon monoxide detector in my vehicle.

Vehicle emits odor like sulphur or rotten eggs, possibly carbon monoxide, when accelerating rapidly or unexpectdly. It always happens when accelerating, pressing gas to merge onto highways or to pass cars on highways. I took my Explorer to dealership purchased from several months after purchasing, but was told nothing was wrong. Netween Feb and May 2016 is when I made appointment at dealer for them to take a look. The problem still exists to this day. I roll the window down to let the smell out when it happens.
