2014 Volkswagen Passat fuel/propulsion system problems

“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…”

“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.”

“Car started to stall, the spark plugs, injectors, sensors all replaced. I go to pickup the car on three different occasions and it won't go 1/10 of a mile without stalling and refuses to start. The garage I was dealing with refuses to work on it any more. I think this seems to be a common problem with the 2014 Passats, but I don't see where anyone's has been fixed. The stalling has happened on multiple dates. Now it's at a garage and can't even get it to dealer and have already spent over 1000.00”

“To Whom It May Concern. Good afternoon. I really need your help on this. This particular vehicle has a defective DEF emission system that renders the car inoperable when the DEF sensors start acting up. Between 2022-2023, I took this vehicle to the Volkswagen dealership on numerous times, over ten different times. This vehicle was still protected under a factory emissions DEF extended warranty. The engine mounted diesel injection pump was changed by me when the Volkswagen dealer refused to honor the defective diesel injection pump. The DEF emissions systems has had numerous issues including shutting off on the freeway due to defective DEF sensors. Between 2022-2023 I was forced to keep the vehicle on for up to 96 hours costing me considerable expenses in fuel, and abnormally high mechanical wear and tear on my vehicle because I was unable to turn the vehicle off due to a Volkswagen diesel no-restart emissions issue that can only be repaired at the Volkswagen dealership. VWOA has acted in extremely bad faith causing unnecessary hardship on their customers that erroneously purchased a Volkswagen Passat diesel with the DEF emission system. Volkswagen ripped me off…”

“High pressure fuel pump failed contaminating entire fuel system. Causing about $4,000 in damage. Have 108,000 miles. Passats up to 2012 are warrantied up to 120,000 miles.”
