INFINITI of Clarendon Hills responded

Thank you for taking the time to share your feedback. We truly value every customer’s experience, and we understand how frustrating unexpected repairs can be. After carefully reviewing your vehicle’s full history, we would like to provide additional clarity. Your INFINITI was originally sold new by our dealership and received all factory-recommended services during the original owner’s term. When you purchased the vehicle nearly four years ago with approximately 59,000 miles, it met all INFINITI Certified Pre-Owned standards and passed inspection at that time. During your ownership, you drove approximately 60,000 miles, and the maintenance costs you incurred over four years were well within the normal range for any luxury vehicle and more in-tune with a Honda or Toyota. With regard to your INFINITI CPO warranty, the manufacturer provides this coverage at no cost to you, and it remains active as long as required maintenance is performed at the intervals outlined in the owner’s manual. When your engine concern was recently evaluated, INFINITI determined that sludge was present. Unfortunately, engine sludge can only form when the required maintenance intervals—time or mileage—are exceeded. Because of this finding, the manufacturer elected to cancel the powertrain portion of the policy. This decision is made solely by INFINITI, not the dealership, and we do not have the authority to override a manufacturer’s determination once evidence of improper maintenance is documented. We are genuinely sorry for the frustration this has caused. Our goal is always to be transparent, helpful, and supportive throughout ownership. While we cannot reverse the manufacturer’s policy decision, we are more than willing to review your repair options. Please contact our management team directly so we can discuss next steps and try to find a solution that helps you moving forward.
