The vehicle intermittently failed to start. The dealer was unable to duplicate the failure or determine the cause of the failure. The vehicle was not repaired. The vehicle was taken to another dealer, Atlantic Coast Acura ([address], Jacksonville, [ZIP]); who was unable to diagnose the vehicle.
The first time I heard the engine noise was on [XXX]. I brought the vehicle to the [dealer] 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.
