What owners report

I keep adding oil and the dealership says there's nothing wrong. For electric problems the speakers have static noise and the screen goes black and turns on hours later. I took in my recently they said there wasn't any problems with the car but I literally deal with it everyday. I told them my car shakes when I brake on high speed they said they checked car but found no issues I personally do not feel safe driving my car at all.

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.

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 connectors. The vehicle's dealership service department documented extensive galvanic corrosion and shorting inside the primary vehicle computer pins due to this blue-green fluid pooling. …

The contact owns a 2017 Volkswagen Passat.

The Passat stalls when traveling at low speed and/or from a stop, battery light turns on and loses all engine power, and will not restart for a period of time (10mins to 2 hours). This has happened on a residental street and on the highway when merging onto an on-ramp. There is no loss of electrical power and the starter attempts to turn the engine over but the car will not start. After multiple starting attempts the cars ECP light will turn on. My safety was put at risk when this occured on the highway and I needed to be push the car to the shoulder. The car has been towed to the VW dealership three times and not been reproduced at the dealership. The dealership replaced the car's oxygen sensor and cam shaft position sensor and this did not fix the stalling issue. Dealership has told me no faults have been recorded.
