2018 Subaru Wrx

Shortly after purchase (within 1 month), a strong raw gasoline vapor odor began entering the passenger cabin, strongest near the driver’s side rear seat and rear wheel well area. The odor intensifies at idle and after short periods of driving, filling the interior cabin with fuel fumes. The smell is so strong that it causes dizziness and headaches when operating the vehicle. This is not an isolated occurrence — Subaru’s own service technicians were able to replicate the issue and confirmed the smell, but reported that smoke and pressure testing showed “no leaks.” Despite replacing the evaporative canister, purge valve, and fuel check valve, the problem persists. The dealership has admitted they cannot determine the source of the vapors. Safety Concern: This condition presents a serious safety hazard because: •Fuel vapors are toxic and pose an immediate health risk to occupants breathing them inside a closed cabin. •Gasoline vapors are highly flammable, creating a potential fire/explosion risk if vapors accumulate near ignition sources. •Subaru has suggested the condition is “normal under certain circumstances” and advised me to alter my driving habits (avoid idling, use engine braking). This is not an acceptable or safe resolution. Attempts to Remedy: •Vehicle has been at the Subaru dealership for over two weeks. •Multiple components in the evaporative emission system were replaced (canister, check valve, purge vent). •Subaru engineers have been contacted but no permanent fix has been provided. •Dealership admitted another customer reported a similar issue in a newer model, but stated it was “normal.” Summary: This is not normal vehicle operation. A car cabin filling with raw fuel vapor represents a defect affecting safety. Subaru has failed to remedy the issue despite multiple repair attempts, and is minimizing it rather than acknowledging it as a defect.

I have been experiencing a strong fuel odor both inside and outside the cabin when starting the engine. After several months of experiencing this issue, I recently had my vehicle fully inspected by an authorized Subaru dealership, and they confirmed a critical fuel leak issue. The dealership discovered that the high-pressure fuel pipe is leaking, as confirmed by a camera inspection of the engine bay. They have deemed the vehicle unsafe to drive and have strongly advised against further use due to the potential fire hazard. It is important to note that my vehicle has never been involved in an accident, and no prior mechanical work has been performed in the affected area, which suggests this may be a manufacturing defect.
