Idaho Code § 48-913: Dealer liability.

Nothing in this chapter imposes liability on a dealer or creates an additional cause of action by a consumer against a dealer, except for written express warranties made by the dealer apart from the manufacturer’s warranties. The manufacturer shall not charge back or require reimbursement by the dealer for any costs, including, but not limited to, any refunds or vehicle replacements, incurred by the manufacturer arising out of this chapter, unless there is evidence that the related repairs had not been carried out by the dealer in a timely manner or in a manner substantially consistent with the manufacturer’s published instructions.
