Lemon laws are American state laws that provide a remedy for purchasers of cars and other consumer goods in order to compensate for products that
repeatedly fail to meet standards of quality and performance. Lemon laws vary from state to state. Most state lemon laws specify that a manufacturer must provide a refund or replacement for a defective new vehicle when a substantial defect cannot be fixed in four attempts, a safety defect within two attempts or if the vehicle is out of service for 30 days within the first 12,000 to 18,000 miles or 12 to 24 months.
Your vehicle is NOT designed to use premium gas. Just know that all you're doing by using it is wasting money.
