There is a gas leak by rear tire. The mechanics that changed my tires said it was water. Went for an oil change, and they refused to do it because it's a gas leak. They can't tell where it's coming from.

When does it fail?
Of the 12 electrical complaints filed for the 2010 Volkswagen Passat, here's the actual mileage breakdown — failures cluster heaviest at 0-25,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
No new NHTSA electrical complaint has been filed on this vehicle in over 5 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: 2010 Passat owners report recurring electrical failures—battery drain, stalling, fuel pump issues, and wiring shorts—with some creating highway safety hazards. Multiple owners faced expensive repairs or refusals by dealers to acknowledge design defects; one experienced fuel pump control module failure even after recall repair.
Owners describe a pattern of electrical and fuel system failures that spans the 2010 Passat's lifetime. The most serious involve sudden engine stall—parking brake lights come on, acceleration cuts out, and the vehicle shuts down on highways. One owner had this happen twice, once during recall repair and again immediately after, nearly causing accidents.
Battery drain is chronic and widespread. Multiple owners replaced batteries repeatedly, with diagnostics pointing to a defective radio head unit drawing power even when the car sits off. The radio itself fails outright: display blacks out, speakers die, Bluetooth cuts. When offered a fix, one owner faced an $800 replacement cost after paying $125 for diagnosis.
Wiring in the trunk frays and shorts from repeated opening and closing, killing the rear camera, license plate lights, and trunk release. Tail light wiring shorts cause repeated bulb burn-outs that require physical tapping to work temporarily. One owner got pulled over multiple times for non-functional lights.
Fuel system issues include a cracked fuel manifold under the rear seat spewing fuel onto electrical connections—a fire hazard—and recurring fuel pump cracks attributed to pressure buildup. One owner replaced the pump three times.
Door locks and power windows fail electrically. One owner paid $2200 for a window and lock repair, then faced another $1000+ estimate for a stuck driver-side door. Dealerships sometimes deflect from these failures or claim customers are liable for diagnostics and towing.

Symptoms owners cite: Engine stalls without warning; Check engine light illuminates; Burning smell from backseat; Engine will not restart; Visible melting of fuel control module
Codes mentioned: NHTSA 17V509
Repairs/costs cited: Dealership performed recall repair; however, same failure recurred within 1 mile of completion. Owner suspects collateral damage to fuel system wiring or continued module defect.
Recalls/TSBs owners mention: NHTSA recall 17V509 issued; dealership repair performed but did not resolve underlying issue. Dealership claimed post-repair failure may be unrelated to recall and customer may be liable for diagnostics and towing.
Chronic battery drain
Vehicle constantly drains battery despite replacement; owner has purchased three batteries. Diagnostics confirmed dead radio unit draws power even when vehicle is off. Battery drains accumulate over days when car sits.
When: Intermittent; occurs even when vehicle is parked and turned off
Symptoms owners cite: Battery dies repeatedly; Radio head unit nonfunctional; Vehicle loses power while driving
Repairs/costs cited: Owner replaced battery three times. Auto shop diagnostics identified defective radio as drain source. Radio replacement quoted at $800 by VW dealership.
Radio/infotainment head unit failure
Center console radio head unit stops working suddenly and remains nonfunctional for extended periods (two years reported). Display blacks out, speakers silent, Bluetooth disabled. Unit draws parasitic power from battery.
When: Sudden failure during highway driving; persistent over multiple years
Symptoms owners cite: Radio display blacks out; Speakers produce no sound; Backlighting goes dark; Bluetooth connectivity lost; Battery drain from defective unit
Repairs/costs cited: Owner refused $800 replacement offered by dealership; $125 diagnostic fee also charged. Problem remains unresolved.
Intermittent stalling and loss of power during acceleration
Vehicle loses ability to accelerate and shuts down unexpectedly while driving, sometimes triggered by parking brake indicator light. Creates immediate highway hazards.
When: During highway driving
Symptoms owners cite: Parking brake indicator light illuminates; Loss of acceleration capability; Complete engine shutdown; Engine will not restart
Repairs/costs cited: Vehicle required towing to dealership. Dealership service manager acknowledged issue is known but not fully recalled.
Recalls/TSBs owners mention: Dealership indicated VW is aware of the issue but has not issued full recall. Letters were issued to 2009 customers. Owner requested buyback; VW refused.
Fuel manifold cracking and fuel leakage onto electrical harness
Fuel manifold located under rear seat cracks from pressure and wiring harness placement, causing fuel to spray onto electrical connections. Presents fire and explosion hazard.
When: Not specified; related to structural pressure from backseat occupancy
Symptoms owners cite: Fuel manifold cracks; High-volume fuel spill onto electrical connections; Visible fuel leakage
Repairs/costs cited: Owner identified poor engineering and wiring harness placement as cause; fuel sprayed directly onto electrical fuel pump connections.
Trunk wiring harness wear and shorts
Wiring in trunk area wears, frays, and shorts as trunk hatch opens and closes repeatedly. Affects multiple electrical systems including rear camera, license plate lights, and trunk release mechanism.
When: Progressive failure with repeated trunk operation
Symptoms owners cite: Rear view camera becomes nonfunctional; License plate light cuts out; Trunk electrical handle becomes disconnected; Trunk cannot be opened from rear of vehicle
Tail light wiring shorts and multiple light failures
Short in tail light wiring also affects trunk wiring due to design. Wiring bends and wears from trunk opening/closing, causing shorts in tail lights, reverse lights, fog lights, and trunk release.
When: Progressive with trunk operation cycles
Symptoms owners cite: Tail light burns out repeatedly (requires tapping to activate intermittently); Reverse light failure; Fog light failure; Trunk release malfunction; Requires physical tapping of light cover to temporarily restore function
Repairs/costs cited: Owner taps light cover to restore temporary function; owner pulled over multiple times for nonfunctional lights.
Engine misfires and fuel pump electrical problems
Vehicle experiences multiple misfires and fuel pump electrical faults creating hazardous driving conditions. Speed thermometer jumps erratically, affecting throttle response.
When: During highway driving
Symptoms owners cite: Engine misfires; Speed thermometer gauge fluctuates; Loss of throttle response; Engine requires repeated restarts during driving
Clock spring failure and horn/steering wheel button malfunction
Clock spring fails; horn and steering wheel button controls stop functioning. Dealership quoted $731 for replacement but owner suspects VW is deflecting from the actual recall issue.
When: Not specified; issue present when brought for airbag diagnosis
Symptoms owners cite: Horn inoperative; Steering wheel button controls nonfunctional
Repairs/costs cited: Dealership quoted $731 for clock spring replacement.
Recalls/TSBs owners mention: Dealership attributed to clock spring failure; owner suspects this is deflection from actual recall issue.
