The contact owns a 2021 Volkswagen Passat. The contact stated that while driving, the check engine warning light remained illuminated. The vehicle was taken to a local dealer, where it was diagnosed with torque converter failure. The contact stated that the breather box was previously replaced by a local independent service center. The manufacturer was made aware of the failure. The failure mileage was approximately 80,000.

The vehicle was brought to Bill Jacobs Volkswagen in Naperville, IL to have three open, mandatory federal campaigns and emissions modifications completed. The dealership is actively practicing illegal 'recall steering' by holding the vehicle hostage. The service department refuses to perform the free federal campaigns unless the owner first authorizes between $2,500 and $3,000 in unrelated diagnostic and repair fees out of pocket. The dealership falsely claims that the vehicle must be 'brough to specification' at...

My car consumes an over abundant amount of oil about 1 quart every 1000 to 1500 miles. There is a civil lawsuit right now about the piston rings having low tension and my car has every symptom of this. This could lead to turbo issues, and several thousands of dollars in repair costs. I've already had to replace my oil pan, timing cover, and pcv and the car only has 80,000 miles on it.

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.

A major engineering and material design failure occurred involving internal fluid containment seals, resulting in a severe electrical safety hazard. Pressurized engine coolant breached an internal component seal and began migrating internally directly through the vehicle's engine wiring harness via capillary/siphoning action. The fluid used the sealed wiring loom as a literal pipeline, traveling inside the wire insulation to bypass all outer weather seals and completely flood the Engine Control Module (ECM) pin...

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,...

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.

The contact owns a 2017 Volkswagen Passat. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power, with the check engine warning light and an unknown warning light illuminated. The contact was able to restart the vehicle; however, the failure recurred, causing the vehicle to intermittently start and stop.

After recall 20AE (Fuel Pump Control Module) was completed at Performance Volkswagen in Lyndhurst, NJ, my vehicle began shutting off while idling and displayed code P0087 - Fuel Rail/System Pressure Too Low.
