Acura issued a #XG1 2015-20 acura connecting rod bearing stop sale in October 2022 due to concerns about the durability of the connecting rod bearings. This stop sale affects all 2015-20 Acura TLX, TLX-L, and MDX models equipped with the 3.5-liter V6 engine.
According to Acura, the problem is caused by a manufacturing defect that can cause the connecting rod bearings to fail prematurely. This can lead to catastrophic engine damage and could result in a loss of power while driving. Acura has not released any specific details about the defect, but it is believed to be related to the bearing material or the machining process.
The stop sale order means that no affected vehicles can be sold or leased until the problem has been fixed. Acura is currently working on a fix for the problem, and it is expected to be available in early 2023.
If you own an affected vehicle, you should contact your local Acura dealer to schedule an appointment for the repair. The repair will be covered under the Acura warranty.
