Gas smell and electronic issues. I bought my vehicle brand new. I first noticed smelling gasoline after the first oil change, so I had driven several months.the dealership blamed it on my undercoating stating that's what I'm smelling.it's gas definitely.I asked them to drive it a week since the smell comes and goes.they refused.it still does it and I have given up trying to get the dealership to find the issue.they did state the flex is the same base as the police vehicle that has the gas emission leak.2nd problem is "no key detected" light comes on when driving.just yesterday my back up cam stayed on while driving.it was distracting and I felt a hazzard.I tried turning the vehicle off and on and that didn't work.after parking for an hour and trying again things went back to normal.when th

I am getting a "Transmission Not In Park" error that will also sometimes flash "Door Ajar" while driving. Door appears to be closed - not sure if it's latched, transmission is obviously NOT in park because the car is moving. I'm concerned that this shouldn't be driven and is a safety issue.

My 2016 Ford Flex’s reverse camera has been shorting out, blinking off and on. If the camera does come on the picture is upside down. This has been happening for over a month and I have not had it looked at. This is similar to the most recent back up camera recall for other Ford vehicles for this year range.

11/26/2018 32,000 mi ODI #11154082.0

"takata recall" my engine light went on 2000 miles before my manufactures warranty expired. I have a Ford shop here, but they are rated so low and I hear nothing but bad stuff about them, so I called the next closest 95 miles away in spearfish, sd. I explained to the guy what code the engine threw, but my light is now off. He said not to come in, until my engine light came back on. Meanwhile my engine still hisses and the exhaust odor is so strong inside and outside of the vehicle. I have 36,879 miles on my 2016 and either have an exhaust leak from the headers or the manifold. The engine light won't come back on and noone will check the vehicle without it on. There is no reason for my "newer" vehicle to have an exhaust leak to this extent.
