BBB is useless. Get it fixed by a knowledgeable repair facility. Send Autonation time-bound letters certified mail, return receipt requested, summarizing the situation and asking for reimbursement. If no resolution after a couple of attempts, sue them in small claims court in your county for breach of contract, material misrepresentation and failure of duty of reasonable care. Look up the theories online. Tie the problem to what they did/promised. The filing fee is small, and they may respond to/resolve with you prior to your court date, but be prepared to state your case to recover repair and filing costs.
