What stands out
Owners have filed 30 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.
Electrical accounts for 29% of all owner complaints filed against this vehicle, across 8 categories tracked.
The failure pattern owners describe
Ignition switch failure is the most serious and common complaint. The switch intermittently pops to the OFF position while driving at any speed, shutting down the engine and cutting power to steering and brakes—exactly what happened when one driver crashed into a median at 55 mph, airbags didn't deploy, and the driver broke both feet and got a concussion. Owners report stalls at 10 mph, 25 mph, 50 mph, and 70 mph, often requiring multiple restart attempts. Some vehicles stall six times or more. The key can be removed from the ignition while the vehicle is moving. Cadillac issued recall NHTSA 14V355000 (Electrical System), but the fix was just enlarging the key hole—dealers told owners this does nothing to stop the switch from popping off. A complete switch replacement costs $1,090. Repair parts were unavailable for months during the recall period, leaving owners stranded.
Rear window regulators fail regularly, leaving windows stuck down. Dealers quote over $500 per window. Multiple 2002–2005 models have the same problem, and owners report seeing many of these cars with back windows taped shut because people can't afford the repair.
A few owners experienced complete electrical system failure after hitting a road bump—all lights, gauges, and controls went dead. One driver lost headlights, turn signals, interior lights, speedometer, and window controls during highway driving and had to navigate by streetlights. One heated steering wheel caught fire and smoked. Another owner's A/C and headlights won't stop running on their own.
Failure modes owners describe
Ignition switch failure and stalling
The ignition switch intermittently shuts off while driving or fails to keep the engine running, resulting in complete engine stall. Owners report the switch pops to OFF, the key can be removed while driving, and the vehicle stalls at various speeds. In severe cases, the loss of power causes loss of power steering and braking, creating dangerous conditions. Multiple restart attempts are often required to get the engine going again.
When: 25,000–173,000 miles; occurs during normal driving at speeds ranging from 10 to 70 mph
Symptoms owners cite: Engine stalls without warning while driving; Ignition switch pops to OFF position; Key can be removed from ignition while vehicle is in motion; Vehicle fails to start intermittently or requires multiple restart attempts; Loss of power steering and braking during stall events; All electrical systems shut off during failure
Repairs/costs cited: Dealer recall NHTSA 14V355000 addressed by widening the ignition key hole, but owners report this does nothing to prevent the switch from popping off. Complete ignition switch replacement costs $1,090. Replacement parts were unavailable for extended periods during recall service period. Some owners replaced the switch multiple times with recurring failures.
Recalls/TSBs owners mention: Recall NHTSA 14V355000 (Electrical System); manufacturer stated the recall fix (key hole enlargement) does not address the faulty switch itself. Replacement switch available only at owner expense after recall completion.
Electrical system cascade failure
Following a road bump or impact, the entire electrical system appears to fail progressively. Warning chimes alert the driver to ABS, suspension, and airbag inactivity. Speedometer stops working, all interior and exterior lights go dark, turn signals and headlamps become inoperative, and windows cannot be opened. The vehicle becomes essentially dead-stick and requires towing.
When: Mileage and exact timing not specified in narratives; occurs during highway driving
Symptoms owners cite: ABS and suspension system indicators inactive; Airbag system failure warning; Electrical charge low warning; All warning lights illuminate; Speedometer failure; Headlamps, turn signals, interior lights inoperative; Window motors inoperative; OnStar unable to connect
Repairs/costs cited: Vehicle towed to dealer; no repair details provided in narrative
Power window regulator failure (rear windows)
Rear window regulators fail, leaving windows stuck in the down position. The motor runs but the regulator mechanism is broken, so the window cannot be raised. This is a widespread issue across 2002–2005 Deville model years. Multiple windows in the same vehicle can fail sequentially.
When: Model years 2002–2005; no specific mileage stated
Symptoms owners cite: Rear window stuck in down position; Motor power present but regulator mechanism broken; Window will not raise
Repairs/costs cited: Dealer quoted over $500 per window regulator replacement. No parts or brand specified.
Heated steering wheel electrical fire hazard
When the heated steering wheel feature is activated, the heating element overheats, causing visible smoke and burning sensation on the driver's fingers. The owner immediately switched off the feature and has not used it since.
When: Winter driving; no mileage stated
Symptoms owners cite: Smoke visible from heated steering wheel cover; Burning sensation in driver's fingers during use
Repairs/costs cited: Not repaired; feature disabled by owner
Recalls/TSBs owners mention: No recalls found by owner
A/C and headlight electrical control malfunction
A/C compressor cycles on and off by itself while the vehicle is stationary and in motion. Headlights turn on automatically whenever the vehicle is placed in Drive, regardless of the headlight switch position. The A/C control display shows both the fan and auto icons simultaneously, and the auto icon cannot be turned off.
When: Began July 6, 2017; increasing frequency
Symptoms owners cite: A/C runs intermittently without operator input; Headlights illuminate automatically in Drive; A/C display shows fan and auto icons simultaneously; Auto icon will not deactivate; Problem occurring multiple times per day
Repairs/costs cited: Alternator replaced (May 2016); battery replaced (May 2016); both checked and confirmed good (July 18, 2017). Online searching revealed many owners reporting the same issue with no solutions.
