No, a dealer cannot force you to buy an extended warranty. In most countries, including the United States, the decision to purchase an extended warranty is entirely voluntary. It is illegal for a dealer to coerce or pressure a customer into buying an extended warranty or any other product or service.
When you buy a product, such as a car, the dealer may offer you an extended warranty as an additional option for an extra cost. It is up to you to decide whether you want to purchase the extended warranty or not. You have the right to decline the offer without any consequences or negative impact on the primary purchase.
If a dealer attempts to pressure you into buying an extended warranty or engages in unethical sales practices, you should be cautious and consider seeking assistance from a higher authority or reporting the issue to relevant consumer protection agencies. Remember that as a consumer, you have the right to make an informed and independent decision when it comes to additional products and services offered by a dealer.
