2013 Volvo S60

I am submitting this report to formally document a severe safety-related failure involving my 2013 Volvo S60, VIN # [XXX] . This vehicle is part of the Volvo brand, widely recognized and marketed as among the safest in the world. Incident Summary: On [XXX], at approximately [XXX] in Norwalk, Connecticut, the vehicle experienced a catastrophic mechanical failure while in operation. The auxiliary (serpentine) belt suddenly failed, shredded itself, and wrapped around the timing pulley. Debris from the failed belt entered the timing belt housing — a supposedly sealed and protected compartment — causing the timing belt to jump. This resulted in an immediate loss of engine power while driving, placing me in a highly vulnerable position. Fortunately, I was not on a multi-lane highway or in fast-moving traffic. Had I been traveling on a busier route, the sudden loss of power could have led to a serious crash and potential injury. This failure represented a genuine threat to my safety. Further inspection revealed that: The lower crankshaft sprocket had skipped three teeth due to the intrusion of the auxiliary belt. The timing belt, although not broken, was off track. A new timing belt was installed in an attempt to restart the engine. The engine would crank but failed to start. A compression test revealed zero compression in all cylinders. The valve train was severely damaged (bent valves), and the engine sustained internal mechanical failure beyond repair. Conclusion and Context: This is not an isolated incident. Upon further research, I discovered that this failure — specifically the auxiliary belt disintegrating and compromising the timing belt system — is a known and well-documented problem in vehicles equipped with the B5254T12 Turbo engine. Volvo has been previously alerted to similar cases before. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
