What must a dealer do if they discover a vehicle defect after sale?

Disclosing the vehicle defect immediately and following up with the buyer is essential for maintaining transparency and trust in the dealer-customer relationship. When a dealer becomes aware of a defect after the sale, they have a legal and ethical obligation to inform the buyer. This fosters good customer relations and can protect the dealership from potential legal repercussions.

Taking this action allows the dealer to demonstrate accountability and to assist the buyer in addressing the issue, whether it involves repairs or other forms of rectification. The dealership’s proactive approach can also mitigate dissatisfaction and help in managing the customer's experience positively, which can ultimately lead to better customer loyalty in the long run.

Other options suggest either inaction or insufficient responses to the defect, which could lead to dissatisfaction or legal issues for the dealer.
