2014 Volkswagen Passat engine problems

“The contact owns a 2014 Volkswagen Passat. The contact stated that while driving 35 MPH, the Check Engine warning light illuminated, and there was no heat coming from the front passenger’s or driver’s side air vents. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed. The contact was informed that the engine heater core had failed and needed to be replaced. The contact stated that the failure had occurred on three different occasions. The engine heater core was replaced four times. The manufacturer was notified of the failure and informed the contact that no assistance was available due to the mileage on the vehicle. The approximate failure mileage was 130,000.”

“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…”

“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.”

“There has been an excessive oil consumption in this vehicle , and reading other reports there maybe an issue, also this vehicle has been part of several recalls previously and I am concerned and I don’t feel safe to drive it . I would like for VW to inspect the car free of charge for this particular issue.”

“Heater core has clogged after replacement in less than 12 months. This is the 4th occurrence of this failure on this vehicle. Failure has the risk to overheat engine. VW Technical Service Bulletin has been modified multiple times, but still doesn't fully resolve the issue.”
