What's wrong?
The connecting rod bearing sits between the connecting rod and crankshaft inside the engine. It lets the rod move smoothly as the crankshaft turns, while engine oil keeps metal surfaces from grinding against each other. The bearing has to hold the right oil film and fit the crankshaft surface correctly.
On affected 2015-2020 Acura Tlx, Mdx, Pilot, Ridgeline, and Odyssey vehicles, crankshaft manufacturing equipment was set improperly. The crank pin was ground with a crown, or convex shape, outside specification. That shape puts the connecting rod bearing under the wrong load. The bearing wears, seizes, and damages the engine.
The warning signs are abnormal engine noise, engine stalling, decreased engine output, or a check engine light. If those show up, the engine is already showing symptoms of the bearing problem.
