Took my car for an airbag recall today, took pretty long, but that s not what I m complaining about. Got my car back and notice grease/oil stains inside on the ceiling where they removed the panel to access the side airbags in the rear. Kinda messed up that I have to clean up after a professional. Also, airbag light is still on after the fix and I m already at home. I knew that if I waited for them to get to it, it would ve taken even longer since by the time I got my car back, it was during their peak time. Another thing to note was that they checked my battery and said it was bad and needed to be replaced. I ve had it checked at another place and the battery passed all test.
