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.
