The vehicle must have been taken in for a reasonable number of attempts to repair the defect(s). It is already presumed that your vehicle has undergone a reasonable number of attempts in the following situations:
Via certified U.S. mail, return receipt requested, you need to provide written notification to the manufacturer (not your dealer) describing the vehicle, the defect(s), and all previous attempts to correct the defect. In this notification, you need to request that the manufacturer make a final attempt to repair the condition. Be sure to include your name, address, day and evening contact information, the license number and model type of your vehicle, and the date and location purchased.
The manufacturer then has 7 calendar days from receipt of your notice to notify you of a reasonably accessible repair facility, and then 14 calendar days after delivery of your vehicle to the repair facility to make this repair.
