Fuel pump failure dominates these complaints. Owners describe sudden engine shutdown on highways with zero warning—no dashboard lights, no shaking, just dead. One owner narrowly avoided a crash when the car quit in rush-hour traffic on I-84 in Connecticut; another had to dive for the breakdown lane. Dealers confirm the pump is the culprit and charge around $550 to replace it. The problem surfaces at 30K to 102K miles, with one dealer noting failures spike in summer heat. VW has issued no recall for the 2005; a 2003 recall exists, but 2005 owners get no coverage despite identical symptoms. One vehicle had a 2004 all-wheel-drive pump incorrectly installed at the factory.
Fuel tank structural failure is the second major issue. At least one owner woke to gasoline fumes filling his home and found a puddle under the car—the tank was splitting at the seams. A dealer reported seeing six such cases in Boise, Idaho in a single year. Repair cost: $2,500.
Fuel line fractures are documented too, with gasoline spraying onto hot exhaust and igniting one vehicle. NHTSA Campaign 08V156000 covers this, but one owner's VIN mysteriously fell outside the recall, and another had a post-repair leak and burning plastic smell that VW refused to address under warranty.
Fuel tank rusting and repeated check engine light failures round out the reported issues.
Failure modes owners describe
Fuel pump failure
Fuel pump stops delivering fuel to engine, causing sudden stall with no warning lights or dashboard indication.
When: Occurs at varying mileages; narratives mention 30K, 50K, 102K miles. Dealers report failures increase during summer heat.
Symptoms owners cite: Engine dies suddenly while driving; No warning lights on dashboard; No preliminary shaking or noise; Vehicle will not restart after stall
Repairs/costs cited: Fuel pump replacement reported at $550. Narrative #1 found a 2004 all-wheel drive pump had been installed on a 2005 front-wheel drive car.
Recalls/TSBs owners mention: VW stated 'this happens' but offered no explanation. Recall issued for 2003 model year only; 2005 not covered despite similar failures.
Fuel tank splitting/structural failure
Fuel tank develops cracks or splits at seams, allowing gasoline to leak into the vehicle and surrounding areas.
When: No specific mileage given. One dealer reported seeing six similar cases in Boise, ID in one year.
Symptoms owners cite: Strong smell of gasoline fumes in home/garage; Gasoline pooling beneath vehicle; Visible puddle of gasoline on floor
Repairs/costs cited: Fuel tank replacement cost reported at $2,500. No recall issued per dealer statement in narrative #4.
Recalls/TSBs owners mention: No recall issued according to dealer statement. VW did not acknowledge defect.
Fuel line fracture and heat shield contact
Fuel line cracks or fractures, spraying gasoline onto hot exhaust components, creating fire hazard.
When: Failure mileage not specified. Incidents relate to NHTSA Campaign 08V156000.
Symptoms owners cite: Gasoline spraying out of fuel line; Fuel dripping on hot exhaust; Fuel gauge reading suddenly drops from half-full to empty; Vehicle catches fire
Codes mentioned: NHTSA Campaign ID 08V156000
Repairs/costs cited: Narrative #6 involved total vehicle loss by fire. Dealer stated heat shield did not cause fracture in narrative #5. Replacement cost context not provided.
Recalls/TSBs owners mention: NHTSA Campaign 08V156000 (Fuel System, Gasoline: Delivery) issued. However, narrative #5 describes a vehicle VIN not covered by recall despite appearing to qualify. Narrative #6 received settlement of $2,700 for inadequate repair under same campaign.
Post-recall fuel leak and burning plastic smell
After recall repair for fuel system delivery (08V156000), vehicle develops new fuel leak and odor of burning plastic.
When: Occurred after recall repair was performed; failure mileage approximately 58,000.
Symptoms owners cite: Smell of plastic burning; Fuel leak present
Codes mentioned: NHTSA Campaign ID 08V156000
Repairs/costs cited: Vehicle was not repaired after post-recall failure.
Recalls/TSBs owners mention: Manufacturer stated vehicle was previously repaired under recall and any further repairs would not be free, refusing warranty coverage.
Fuel tank internal rusting
Interior of fuel tank develops rust, creating contaminated fuel that may damage engine components.
When: Not specified; appears to be design/material issue present in used/aged vehicles.
Symptoms owners cite: Visible rusting inside fuel tank; Rusty liquid in fuel system
Repairs/costs cited: None provided; owner seeking replacement.
Recalls/TSBs owners mention: Dealer and VW refuse replacement, claiming not a warranty issue despite owner contention of manufacturer defect.

Check engine light illuminates multiple times since vehicle was new, with no permanent resolution despite repeated dealer service visits.
When: Recurring issue since vehicle purchased new in June 2005.
Symptoms owners cite: Malfunction indicator lamp (MIL) comes on suddenly; Recurrent failures despite repairs
Repairs/costs cited: Dealer repairs MIL issues at customer cost each occurrence; no lasting fix identified.
Recalls/TSBs owners mention: VW did not address root cause despite customer complaints during service visits.
