What stands out
Electrical accounts for 42% of every owner complaint on file for this vehicle — the dominant problem area across 3 categories tracked.
No new NHTSA electrical complaint has been filed on this vehicle in over 7 years — the issue may be aging out of the active population.
General Motors LLC (GM) is recalling certain model year 2011-2012 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles
If stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags may not deploy, increasing the risk of occupant injury.
Fix: GM will notify owners, and dealers will inspect and replace the ignition lock housing, as necessary, free of charge. The recall began on February 12, 2015. Owners may contact GM customer service at 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14696 for the original equipment, and 14912 for the service replacement parts.
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.
Service Bulletin15-06-03-001FMar 2025
This service bulletin provides information to diagnose batteries that have set for a long period of time and/or cold weather climates and testing those batteries.
This bulletin advises the dealers to maintain the vehicle stock on hand by doing a full inspection on the vehicles before being sold (prepping) to the customer.
This Preliminary Information communicates to the dealer the process for downloading or updating operating software for the Tire Pressure Monitor, Active Fuel Injector tester, multi media tester, PICO Scope, GR8 starting/charging tester and Vehicle Data Recorder tools, giving website address and step by step instructions to complete the update.

The failure pattern owners describe
Owners consistently report cascading electrical failures—usually starting with one symptom (door lock cycling, dash light flickering) but snowballing into multiple simultaneous system malfunctions. During these episodes, doors lock and unlock on their own, dashboard lights blink erratically, the radio cycles on and off, seat heaters activate without input, and the climate control goes haywire. Some owners experience engine revving or hesitation; others lose power entirely at highway speeds.
The most dangerous failures involve braking and engine control. One owner reported the brake pedal sinking into the floorboard and the truck accelerating instead of stopping—they crashed into a tree at 9,000 miles. On a hybrid model, a bad battery cell produced the same brake failure at 47,000 miles. A second group of owners report the engine cutting off mid-drive or entering a limp-home mode; one owner had the PCM replaced, found the oil pressure sensor faulty, and suspects the real culprit is camshaft bearing wear.
The recurring lock/unlock problem appears across multiple vehicles. Dealerships cannot replicate it, and Cadillac's customer service denies it exists. One service manager told an owner that Cadillac technical support acknowledges the issue but has no fix. Episodes typically last from one mile to ten miles before systems return to normal, leaving owners stranded with unpredictable, unrepaired safety hazards.

Failure modes owners describe
Random door lock/unlock cycling
Doors lock and unlock without operator input while the vehicle is parked or moving. Multiple owners report this occurs randomly and cannot be replicated at the dealer for diagnosis.
When: Intermittent; occurs while parked and while driving
Symptoms owners cite: Doors lock and unlock randomly; Occurs without warning; Cannot be replicated by dealer; Unsafe when vehicle unlocks while moving
Repairs/costs cited: No successful repairs reported; dealers unable to diagnose. Vehicle spent 45 days at dealership in one case with no resolution.
Recalls/TSBs owners mention: Cadillac Customer Assistance Center denies the problem exists because it cannot be replicated. Service manager reports this is not isolated and Cadillac technical support is aware of similar complaints.
Electrical system malfunction with cascade effects
Simultaneous failures across multiple electrical and electronic systems including door locks, climate control, dashboard displays, and engine control. Often accompanied by drivability issues.
When: Intermittent; episodes last 1 mile to 10+ miles before clearing
Symptoms owners cite: Doors lock and unlock; AC and heating cycle on; Seat heaters activate on their own; Clock blinks; Navigation screen blinks on and off; All dash lights illuminate; Radio cycles on and off; Engine revs or hesitates; Engine loses power then restores power
Codes mentioned:C0900
Repairs/costs cited: No successful repairs reported in narratives provided.
Engine stalling with loss of electrical power
Complete loss of electrical power while driving on the highway. Engine upshifts without operator input, lights and door locks fail, then power intermittently returns.
When: While traveling on highway; mileage not specified
Symptoms owners cite: Complete loss of electrical power; All lights go out; Door locks fail; Engine upshifts into 2nd or 3rd gear on its own; Engine refuses to accelerate; Power cycles on and off repeatedly
Brake system electrical failure
Brake pedal loses pressure and vehicle accelerates instead of stopping when brakes applied. Occurs during inclement weather. Results in loss of vehicle control and collision.
When: At approximately 9,000 miles
Symptoms owners cite: Brake pedal sank into floorboard; Vehicle accelerated instead of stopping when brakes applied; Complete loss of braking ability
Repairs/costs cited: Brake sensors replaced, central computer recalibrated at dealer
Recalls/TSBs owners mention: Manufacturer contacted after repair
Hybrid battery cell failure causing brake electrical loss
Bad cell in hybrid battery leads to loss of electrical power in brake system. All warning lights illuminate and brake pedal sinks into floorboard without stopping ability.
When: At 47,000 miles
Symptoms owners cite: All warning lights illuminated; Brake pedal sank into floorboard; Vehicle failed to stop; Failure recurred twice
Repairs/costs cited: Hybrid battery replaced
Electrical system malfunction causing stalling and flickering
Interior and exterior lighting flickers and vehicle stalls. Vehicle restarts independently.
Repairs/costs cited: Vehicle towed to residence, not diagnosed or repaired
Recalls/TSBs owners mention: Manufacturer made aware of failure
Engine control module and fuel system electrical failure
Engine cuts off or enters low power mode. Replaced with new PCM but issue persisted. Subsequently diagnosed as oil pressure sensor and possibly camshaft actuator starvation.
When: Under 80,000 miles
Symptoms owners cite: Engine cuts off while running; Low power mode activation; Engine shuts down while running; Low oil pressure warning light
Repairs/costs cited: PCM board replaced; issue remained. Oil pressure sensor replaced; problem recurred. Owner suspects camshaft actuator and bearings are bad due to oil starvation.
Ignition switch electrical failure
Key can be removed from ignition switch while vehicle is in operation, which should not be possible.
When: At approximately 66,000 miles
Symptoms owners cite: Key removable from ignition while vehicle is operating
Repairs/costs cited: Not diagnosed or repaired

While traveling on the highway the vehicle randomly lost electrical power, lights, door locks, everything and the engine upshifted into second or third gear completely on its own, then refused to accelerate. The electrics would come back on and then go off again. The electronic went completely berserk and presented a huge safety issue for my wife, children and I.
