Which of the following is considered a deceptive trade practice?

Failing to provide a written warranty is a significant issue in the context of deceptive trade practices, as it can mislead consumers about their rights and the protections available for their purchase. When a dealer advertises a vehicle, customers often expect some form of warranty or assurance regarding the vehicle’s condition and performance. Not providing this written warranty can lead buyers to assume they have more security and recourse than they actually do, which fails the standard of transparency and fair dealing expected in vehicle sales.

On the other hand, the other options highlight practices that more directly mislead consumers regarding the specifics of the vehicle itself, such as misrepresenting mileage or exaggerating its condition. While these are also considered deceptive practices, the failure to provide a warranty represents a fundamental issue of consumer rights that carries significant implications for trust in the sales process. Thus, it’s viewed as a particularly egregious example of deceptive trade practice.
