NHTSA Complaint #11686222 — 2022 VOLKSWAGEN ATLAS

My Volkswagen Atlas has a recurring check engine light and start/stop error light. The LD pump and valve have been replaced multiple times, but the issue persists. Volkswagen now says the problem is the carbon canister, which is covered by TSB VWP-23-04 (NHTSA ID MC-10235143-0001) extending warranty to 15 years/150,000 miles. The bigger concern is safety: the vehicle has stalled multiple times while driving, including once in an intersection where I completely lost steering and control until the car was towed. This creates a major safety hazard for myself and others on the road. Despite the TSB coverage, Cardinale Volkswagen in Salinas, CA is refusing to replace the carbon canister under warranty. They also charged me a $240 diagnostic fee, even though the issue diagnosed was later found to be warranty-related. My understanding is that diagnosis and repair of warranty defects should be performed at no cost. This is a clear safety defect: sudden stalling in traffic, loss of steering, and repeated failures of emission-related parts. I am requesting that NHTSA investigate these incidents and Volkswagen’s handling of warranty claims, as drivers are being put at risk of accidents, injury, or worse.
