The vehicle experienced repeated catastrophic engine failures, including failure of a replacement engine. Approximately six months after purchase and at around 80,000 miles, the engine failed and required a complete engine replacement through Volkswagen and the MaxCare service contract. Approximately one to one and a half years later, at around 120,000 miles, the replacement engine also failed. The vehicle developed rough idle conditions, check engine light warnings, timing chain and camshaft-related issues, lubrication-related concerns, and severe engine performance problems. Volkswagen later recommended another complete engine rebuild or replacement along with additional engine-related repairs. The vehicle became non-operable and could no longer be safely or reliably driven. The repeated failure of both the original engine and replacement engine suggests an ongoing defect-related condition rather than normal wear or an isolated mechanical failure. The problems were confirmed and documented by Volkswagen service personnel. Similar engine-related concerns involving oil consumption, lubrication issues, timing system concerns, and engine performance problems are also reflected in Volkswagen Technical Service Bulletins involving this type of engine.

I am reporting a recurring engine defect in a 2014 Volkswagen Passat that has resulted in repeated engine failure and loss of power while driving. Approximately six months after purchase, the vehicle required a complete engine replacement. One to two years after the replacement, the vehicle began exhibiting the same engine-related failures and has since become inoperable again. Manufacturer-issued Technical Service Bulletins addressing these engine defects were issued prior to the sale of the vehicle, indicating the condition was known. The repeated engine failures create unsafe driving conditions, including the risk of sudden loss of power during vehicle operation.
