Purchased a truck from Gateway Ford about 6 months...

Purchased a truck from Gateway Ford about 6 months ago. First off I was sold the vehicle with gas indicator on empty, and I let them know in a survey about this, but received no response from dealer. Not super expensive for gas so not a huge deal. Since then I had to replace break pads, blinker light, and blue tooth is working intermittently. I get that blue tooth and blinker light wouldn't be caught in an inspection before sale, but the break pads should have been caught before putting on a lot. I had the break pads replaced 2 months ago or 4 months after purchase with less than 3k additional miles driven. The breaks started squealing much earlier than that, but I had just put down a significant down pmt with dealer, so I could not go right to a shop for inspection. I did not inform the dealer till recently because they didn't even respond to an empty gas tank, how would they respond to new break pads. Anyways, they reached out to me recently for referrals and I told them of my situation along with providing proof of my invoice of new break pads from a reputable mechanic. I have asked for reimbursement for the break pads since it was clearly sold with poor break pads, but they refuse even with proof. Buyer beware
