NHTSA Complaint #11591787 — 2018 VOLKSWAGEN ATLAS

Our 2018 V6 SEL Volkswagen Atlas is the recipient of a defective fuel injection system. Through discussion with VW service and maintenance staff, as well as research in online VW specific forums, there is defective fuel injectors found in various VW Atlas year and differing engine vehicles. Our particular vehicle had a malfunctioning, defective fuel injector (fuel injector for Cylinder 6) which resulted in massive carbon build up. There is no real detection system for a faulty, leaky fuel injector according to VW service. The carbon build up began with misfiring check engine and ECP error codes. Upon taking it to the dealer, we were made aware that the carbon build up also resulted in mechanical failure of components within Cylinder 6. This would affect drivability of the vehicle while on the road, resulting in severe power or ability to drive loss. Other additional factors aside from the faulty fuel injection system, is the valve gasket was also leaking oil through to spark plugs 2-4, which could result in vehicle fire. We are not sure if the faulty gasket is a result of the faulty fuel injector system. The 2018 VW Atlas was a first year model release, and would not be surprised if significant design flaws and defects are a risk with this vehicle.
