Good morning CKENDZIORA,

I completely understand that you're looking for a way to take care of this yourself. I just wanted to offer my assistance if needed (checking into recall/warranty information on your vehicle, documenting a complaint about a dealership, assisting in working with your current dealer or helping you find a new one).

All the best,
Sarah
