Look like Ford has a software fix to detect a failure before it occurs and to stop a breach from happening.How do they identify which ones are problem engines is indeed the rub. In the absence of a scientific method to propose while sitting across the table from the NHTSA lawyers, the government is most likely to say, "You just need to replace all of them them to satisfy this issue for us." We will see.
But to my point, if they have to replace a couple hundred thousand engines that will indeed be a PR issue.

When the software detects the issue it will stop the breach from happening.May – November 2023: Ford’s Internal Combustion Powertrain and Powertrain Controls Engineering teams tested several engines and analyzed historical calibration data to characterize connecting rod bearing failures for all cylinders. The team used these findings to develop a connecting rod bearing failure detection algorithm which will limit engine speed/load after detecting a bearing that is in the process of failing, and provide notification to the driver. Once the software was developed, the engineering teams tested its effectiveness through dynamometer and vehicle testing. The results of the testing indicate that this algorithm will detect a connecting rod bearing failure and protect the engine from a block breach.
On December 15, 2023, Ford’s Field Review Committee approved the remedy for the 23S27 field action.
Ford does need to fully cover anyone who gets the warning with a new engine.
