After having the takata airbag recall taken care of by franklin ford lincoln the engine oil light was on and the battery kept draining and had to be replaced today. Ford claims that they did nothing incorrect in the recall but prior to taking my car to ford the battery and 02 sensor were in fine working order. After the recall they were not. After replacing the battery today the car still hesitates to start and the AC system keeps making a clicking noise. This was not happening before the recall was performed. I don't think that my car will ever be the same and it is all due to ford lincoln of franklin replacing the airbags.

For the last year experiencing progressively worsening drivability issues. The most concerning is steadily increasing throttle lag (time between applying more pressure to accelerator and vehicle responding), which I view as a safety issue. The vehicle does not respond appropriately when applying throttle, which may increase risk of accident b/c vehicle may not accelerate properly when needed either placing me at risk because it leaves me in the path of another vehicle or prevents my vehicle from expeditiously responding to avoid another vehicle.. Secondarily vehicle now operating almost exclusively in gas power mode (worsening mpg efficiency) but also causing jerking/hesitation when transitioning between gas/EV modes. This powertrain was not designed to work in gas only but as a partnership between gas/EV, therefore in gas alone is not working properly. Internet search reveals many other owners experience same problem. To dealer service x 3 - 1st 2 dealer said nothing wrong. Finally given a ford service bulletin (attached) that ford is aware for at least 4 months and forbids service to the car! Thus I have an unsafe vehicle that ford has no solution for repair for at least 4 months, and no indication of when this will be addressed.

I just purchased this vehicle used from a local dealer on 05/16/2019. I noticed an occasional hesitation when I accelerated sometimes. Conversely, it seemed as though the vehicle suddenly lurched ahead when I was barely engaging the accelerator. This odd occurrence has become more frequent the more I've driven the car. To the point that I looked for paperwork to take the vehicle for possible transmission service. Over the past couple of weeks, I've begun to hear of issues with the ford focus and ford fiesta that sound exactly what I'm experiencing. I use today's date as when it happened, but it has been happening with increasing frequency as I've driven the car.

Whenever we accelerate our vehicle hesitates and then jumps into gear. It has already cut off once and we are worried about our safety.

Driving on highway 24/27 my car just shut off. No warning. Then sputtered. I cruised over to shoulder. The tool light was (wrench) on. I cut off the car and then restarted the car. Very scary. At first I was advised I had bad gas in the car, then I was advised I need a new fuel injection system. Then after cutting off 6 times in the space of one exit to another, I refused to drive the car anymore. The mechanic stated I need a new throttle body and it was replaced. My car still hesitates and accelerates at times.

Driving at 35 MPH lost acceleration, engine idles but when gas peddle is pushed to the floor no power. Called dealership and without hesitation I was told it was the throttle body and that it was a very common problem. Cant believe this is not a safety recall. Very dangerous and scary!!!! And of course car is no longer under warranty. I truly hope this does not happen to someone driving down a highway in heavy traffic. Ford really, really needs to consider a recall, put money on it there will be multiple incidents in the very near future. I have also heard that ford is aware of the problem and changed the part number but are not recalling the original part.
