Glad to hear you got it fixed. It is so frustrating, when a garage tells you they don't see a problem. It's almost like the vehicles know when they are being watched.
I had a co-worker that pursued "Lemon Law" She wasn't able to accept, because it was too expensive. She had driven vehicle for about 5 months & had accumulated 6,000 miles.
Dealer had possession of vehicle for 35 days of the six months. The dealership was requiring her to pay, for every mile driven & also pay the $4,000 rebate, she had received as price discount.
