The contact owns a 2021 Ford Explorer. The contact stated while driving approximately 30 MPH, the contact heard an abnormal sound coming from under the floorboards. The contact slowed the vehicle to listen for the sound, when the contact depressed the accelerator pedal to move forward, he heard the abnormal sound and described it as the sound of a motorcycle exhaust. The contact stated that he drove forward for a few minutes more when the abnormal noise from under the vehicle was louder and he felt that some object was trapped underneath the vehicle and was hitting the underside causing a loud banging noise. The contact stopped the vehicle and looked underneath the vehicle and observed that the passenger-??s side exhaust pipe had detached from the catalytic converter. The contact then checked the driver's side and saw that a crack had opened approximately one inch from where the exhaust pipe was connected to the catalytic convert. The contact stated no warning light was illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the damage appeared to have been made during an attempt to steal the catalytic converter and referred the contact to a muffler specialist. The vehicle was not repaired. The contact took the vehicle to a muffler repair shop where it was diagnosed that the exhaust pipes had rusted, and the passenger-??s side exhaust pipe had detached from the vehicle. The contact did not believe that the rust was the cause in the fracturing of the exhaust pipe from the catalytic converter. The contact researched online and related the failure to manufacturer Customer Satisfaction Program Number: 21E11 Emission Recall (Engine). The manufacturer was informed of the failure. The failure mileage was 58,691.
