What owners report

2026-06-02, Engine
The first time I heard the engine noise was on [XXX]. I brought the vehicle to the Schaumburg Muller Acura dealership and dropped it off on May 20. On May 21, the dealership performed an initial inspection and informed me that they needed authorization to further disassemble the engine in order to determine the cause of the problem. I provided that authorization, and by May 22 the engine had been torn down to the point where the failure could be identified. On May 22, I spoke with my service advisor, Ken, who informed me that the connecting rod bearings were worn and that the engine would need to be replaced. I was sent photographs, a video, and an estimate for the repair totaling $12,943.8
