*** IMPORTANT SAFETY RECALL *** NHTSA Recall No. 22E-063 August 2, 2022 Terex Advance Mixer 7727 Freedom Way Ft. Wayne, IN 46818 Dear Cummins OEM Customer: We are writing to inform you that Cummins Inc. has determined that a safety-related defect exists among a population of certain X15, X12, L9 and B6.7 engines that were manufactured between May 13, 2022 and June 28, 2022. Accordingly, Cummins submitted a Part 573 Defect Notification to the National Highway Traffic Safety Administration (NHTSA) on July 28, 2022 covering potentially affected engines. A copy of Cummins’ initial report is enclosed. Our records indicate that some of these engines have been shipped to you. As more fully described in the Defect Notification, some of the Engine Control Modules installed in this engine population may develop an internal electrical short, possibly resulting in an engine stall without warning, which may lead to an increased risk of a crash. Enclosed is a list of Engine Serial Numbers for potentially affected engines that our records indicate were shipped to your plants. For engines installed in vehicles that have left your control, we encourage you to make a safety defect determination in accordance with 49 USC 30118 et seq. and, as appropriate, to submit a Defect Notification to NHTSA in accordance with 49 CFR Part 573. At your request, Cummins will conduct the recall, including notifying owners pursuant to 49 CFR Part 577, performing the remedy, and submitting quarterly status reports to NHTSA. To facilitate owner notification, Cummins requests that you provide the associated vehicle model identification, VINs and owner contact information. Please work with your Cummins account team leader to ensure that the requested information is provided to Cummins as soon as possible. As a supplier of original equipment, Cummins has no obligation to submit a defect notification to Transport Canada. However, Cummins does, as a courtesy, notify Transport Canada when Cummins submits a defect notification to NHTSA, advising that some OEMs may have affected vehicles. If you have an obligation to report the defect to Transport Canada, we ask that you please provide us with the Transport Canada recall number assigned to your vehicle recall. Cummins cannot mail owner letters compliant with Transport Canada regulations with respect to your recalled vehicles without the recall number assigned by Transport Canada. Cummins will provide the applicable data to you after our mailings are completed so that you can submit the required notification reports to Transport Canada, as well as provide you the completion rate data so that you can submit the required quarterly completion reports to Transport Canada. For engines/vehicles that are still in your inventory, please contact the Customer Quality Assurance representative at the producing engine plant to arrange for repairs. Cummins apologizes for this inconvenience, but we are initiating this action in the interest of our customers’ safety and satisfaction with our products. Thank you for your assistance. Please confirm receipt of this communication. Sincerely, Dave Getz Enclosures: 1. Cummins Part 573 Defect Notification 2. Engine Serial Number list
