What stands out
Owners have filed 38 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This is a notice for software changes with the ODIS diagnostic program to correct the communication during vehicle programming function: A software fix is needed to correct a test that is not reading any information from the battery data module (BDM) and will output:

The failure pattern owners describe
Clockspring failure dominates this cluster. Owners report clicking or ticking noises from the steering column, followed by airbag warning lights, dead horns, and non-functional steering-wheel controls. One customer's part was on backorder for five months; another had the clockspring replaced three times with repeated failures. VW issued recalls for this defect on 2010–2014 models but not the 2015.
Ignition switch and key insertion issues plague these vehicles. Keys won't go in, get stuck in the ignition roughly one in four times when in park, and the vehicle won't start. One dealership acknowledged this as common across all Volkswagens that year but said an extended warranty existed for most models except the Passat.
Window motors overheat and fail. Dealers state this is widespread across all VWs with no fix.
Electrical gremlins span warning light clusters lighting up together—ABS, airbag, steering, check engine, EPC, ESP, alternator, TPMS—sometimes with speedometer dropout and unexpected power loss. Engine stalls occur at highway speeds with battery and check engine lights. Rodents chew through soy-based wiring insulation and fuel lines. Heater cores fail to warm the passenger side. Tail lights and cluster illumination fail repeatedly.
One owner discovered a safety recall scenario: a previous owner disabled the airbag warning light bulb to hide a deployed airbag system.
---
Buyer takeaway: Steer clear of 2015 Passats with electrical history or high mileage. Clockspring failure is common and parts are hard to find; ignition problems, window motor overheating, and rodent wire damage are documented defects with limited manufacturer support.

Failure modes owners describe
Clockspring failure
The clockspring assembly in the steering column fails, disabling the airbag system, horn, and all steering-wheel-mounted controls simultaneously. Multiple owners report a clicking or ticking noise from the steering column before failure, followed by airbag warning light illumination and complete loss of steering-wheel functionality.
When: 35,000–167,000 miles; one failure at 47,000 miles noted
Symptoms owners cite: Clicking or ticking noise from steering column when turning; Airbag warning light illuminates; Horn inoperative; Steering wheel controls (audio, phone, cruise control) stop working; Loud pop from steering wheel during turn; Stiffness or crunch felt in steering wheel
Repairs/costs cited: Clockspring replacement required; cost cited as nearly $700. Multiple reports of backorder availability; one owner reports dealership had part on backorder for 5 months with no ETA. One owner reports clockspring replaced 3 times with recurring failure.
Recalls/TSBs owners mention: VW issued recalls for clockspring issues on 2010–2014 Passat models but not 2015. One owner contacted manufacturer; case was opened but no ETA provided for parts.
Ignition switch/key insertion failure
The ignition switch becomes stuck or won't accept the key, preventing the vehicle from starting or being driven. Key gets stuck in the ignition approximately 1 in 4 times when put into park. One dealer diagnosed a faulty key; another diagnosed the ignition switch needing replacement.
When: 45,000–64,000 miles
Symptoms owners cite: Key will not insert into ignition; Key gets stuck in ignition when in park; Vehicle unable to start
Repairs/costs cited: One repair involved replacement of the key. Another required ignition switch replacement (not performed due to warranty expiration). Owner reports this is a known issue with all Volkswagens of that year, and an extended warranty has been issued by VW for most models except the Passat.
Window motor overheating and failure
Front driver-side window motor fails due to overheating. Dealer stated this is a common issue among all Volkswagens with no remedy available.
When: 43,900 miles
Symptoms owners cite: Front driver-side window fails to function
Repairs/costs cited: Window motor failed due to overheating. Not repaired; warranty had expired.
Recalls/TSBs owners mention: Dealer stated this is a common issue among all Volkswagens and nothing could be done. Manufacturer stated nothing could be done because warranty ended.
Multiple warning lights illumination with performance loss
Instrument cluster displays multiple simultaneous warning lights (ABS, airbag, steering system, check engine, EPC, ESP/ASR, alternator, TPMS) along with loss of speedometer function and intermittent loss of power during acceleration.
When: <UNKNOWN>
Symptoms owners cite: ABS light steadily illuminated; Airbag light steadily illuminated; Speedometer shows 0 (non-functional); Steering system indicator light steadily illuminated; Check engine light intermittent; Electric Power Control (EPC) indicator intermittent; ESP/ASR light steadily illuminated; Alternator indicator light intermittent; Tire Pressure Monitoring light steadily illuminated; Fuel gauge fluctuates wildly; Acceleration drops off intermittently, especially in traffic and at highway speeds
Repairs/costs cited: Owner made no modifications except regular maintenance and new tires. Dealership technical advisor speculated wheel speed sensor at fault but owner lacked confidence in diagnosis.
Infotainment system failure and battery drain
Infotainment system fails to power off when vehicle is turned off, displaying 'download' message and causing complete battery drain.
When: 45,000 miles
Symptoms owners cite: Infotainment system does not turn off when vehicle is shut off; 'Download' message displayed on screen; Battery drain
Repairs/costs cited: Infotainment system replacement required; not repaired.
Recalls/TSBs owners mention: Manufacturer informed contact that vehicle was not covered under warranty.

Repairs/costs cited: Vehicle not repaired due to repair cost.
Rodent damage to wiring and fuel lines
Rodents and mice chew through electrical wires, vacuum lines, and fuel lines due to VW's use of soy-based insulation materials. Soy coating attracts rodents. Vehicles have been disabled by chewed wiring; one owner experienced diesel fuel leak from damaged fuel lines.
When: <UNKNOWN>
Symptoms owners cite: Chewed electrical wires; Chewed vacuum lines; Chewed diesel fuel lines (tank to engine and return lines); Vehicle becomes non-operational; Diesel fuel leak from damaged fuel lines
Repairs/costs cited: All repairs and parts ordered and conducted at local VW dealership; records on Carfax and VWoA servers.

Common questions
How serious is the electrical problem on the 2015 Volkswagen Passat?
It's a meaningful issue. 38 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $850.
At what mileage does the electrical typically fail?
Across the 25 complaints that reported odometer mileage, most electrical failures cluster between 44,000 and 67,000 miles, with the median around 55,000. A quarter of owners report trouble before 44,000; a quarter make it past 67,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $850 for electrical repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to electrical?
No active recalls currently cover electrical issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
