Thank you for your reply.Please be assured that we certainly do not like to see our guests experience the frustration and inconvenience that are associated with unexpected repairs. It is the desire of Lexus Canada to provide sound, durable and reliable vehicles which will require a minimum of service and not only meet, but exceed our guests' expectations. However, there remain instances, such as you have encountered, where difficulties will arise.The Lexus Extra Care Protection (ECP) agreement you purchased covers the costs of repairing your vehicle when a difficulty arises as the result of a manufacturing defect experienced within the parameters of the agreement. Our commitment to you is to repair your vehicle according to the terms of your ECP agreement.Having said that, there are limitations, in terms of what is covered by the ECP.We would like to refer you to the ECP agreement that was mailed to you after purchase. As per the section "Obligations", sub-section "Repairs", coverage is for a repair that is required as a direct result of a defect in workmanship or material of a covered component that caused a malfunction of the vehicle. We would like to take this opportunity to explain that re-calibration of a component is not considered a manufacturing defect.Again in your ECP agreement, as per the section "What Is Not Covered", please note that diagnostic fees are not covered.We thank you again for taking the time to contact us and for allowing us the opportunity to comment. A copy of your correspondence has been forwarded to the appropriate departments within Lexus Canada for their information.
