BACKGROUND Acura is announcing a STOP SALE and safety recall for certain model year 2016–2020 MDX and 2015–2020 TLX V6 vehicles which may have engines containing internal damage at the connecting rod bearings, possibly leading to engine failure. If an engine fails, the vehicle may lose motive power, increasing the risk of crash, fire and resulting injury. During engine manufacturing, some crankshafts may have been built with improper connecting rod journal dimensions, resulting in increased friction between the journals and their bearings. This increased friction could lead to accelerated engine deterioration and possible failure due to a lack of lubrication and excessive heat. If this temporary placeholder bulletin appears during an iN VIN status inquiry, the vehicle is subject to a safety recall. Any affected vehicles in your dealer inventory are on STOP SALE until further notice. Refrain from calling Tech Line for updates. The following suggested text should be included on any repair order for an already sold affected vehicle that comes in for service. This information should be printed out completely and provided to the client any time service is conducted on an affected vehicle, and the recall repair has not yet been completed. Once parts and repair information are available, the normal procedures under Dealer Operations Manual (DOM) 7.2.1 will apply for this recall. Suggested verbiage to be included on the repair order: Client was advised that: The vehicle may be subject to a recall affecting the engine connecting rod bearings. The parts necessary to complete the recall repair are not yet available. Once parts repair kits are available, the registered owner of the vehicle will receive a notice to bring the vehicle in for inspection and possible replacement of the components. Please be advised that clients will still be able to register their vehicles with their respective Department of Motor Vehicles at this time. For any questions or concerns clients may have, you may have them contact American Honda’s Customer Support & Campaign Center at 1-888-234-2138. This bulletin will be updated once the parts information is available.
