What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
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.
The intent of this service bulletin is to identify aftermarket ALDL or DLC interface devices as potential sources for causing multiple customer concerns that do not have other diagnostic methods to identify them.

The failure pattern owners describe
Owners describe a cascade of electrical failures in 2014 Tahoes that create real safety risks. The most severe: uncontrolled door locks cycling while interior lights flash, engine stalling mid-drive with complete power loss, and trailer brake systems engaging without cause during acceleration. One police fleet vehicle at 15,000 miles suffered erratic idle, acceleration hesitation taking several seconds, and uncontrolled surging—unacceptable in a pursuit vehicle.
Service Trailer Brake warnings appear repeatedly across complaints, often paired with instrument panel flicker, radio spontaneous restarts, and airbag light cycling. Starting failures occur intermittently; when the vehicle does run, multiple warning lights cascade on and off. Dealers tested batteries and alternators as good, yet low-battery warnings persist.
The core problem: GM issued NHTSA Campaign 14V614000 (Electrical System) to address these exact failures, but many owners report their VINs excluded from recall coverage despite identical symptoms. Dealers cite missing part availability, delaying repairs weeks or months. One attempted ECM replacement failed to resolve the issue. Owners resorted to power-cycling vehicles for temporary relief or trading them in for non-GM vehicles.

Failure modes owners describe
Uncontrolled door lock cycling with interior light flashing
Door locks cycle repeatedly up and down in conjunction with interior lights flashing on and off. Occurs during driving and can persist upon vehicle shutdown.
When: Occurs during highway driving, multiple occasions reported across mileage ranges up to 74k
Symptoms owners cite: Door locks cycling up and down rapidly; Interior lights flashing on and off; Rear hatch ajar warning illuminating; All doors unlocking independently
Codes mentioned: ECM failure diagnosis reported
Repairs/costs cited: Electronic Control Module (ECM) replacement performed in at least one case; failure recurred after repair. Complaints suggest negative battery cable as underlying cause in some cases.
Recalls/TSBs owners mention: NHTSA Campaign 14V614000 (Electrical System) issued; multiple VINs reported as not included in recall despite matching failure symptoms.
Engine stall with complete loss of electrical power
Engine unexpectedly shuts off during driving, causing hard stop. Vehicle may restart on its own or fail to restart entirely. Multiple electrical warnings precede complete shutdown.
When: First reported in April 2016, recurring every few months; reported at 39k and 74k miles; one instance at unknown speed
Symptoms owners cite: Engine stalls without warning; Hard stop during driving; Complete loss of electrical power; Service trailer brake warning light illuminates before failure; Interior lights flashing; Low battery warning illuminates and extinguishes
Codes mentioned: Service Trailer Brake Control Module indicator
Repairs/costs cited: Battery replacement attempted in one case; failure recurred. Dealer diagnostics found battery and alternator checked out okay despite symptoms.
Recalls/TSBs owners mention: NHTSA Campaign 14V614000 referenced; some VINs excluded from recall coverage despite identical symptoms. Customers report GM refused repair coverage citing VIN exclusion.
Trailer brake control module false activation
Service Trailer Brake Control warning light illuminates during acceleration or driving without legitimate towing load connected. Engages trailer brake system making vehicle unsafe to continue driving.
When: Multiple occasions during highway and subdivision driving; recurring intermittently; at least one instance at 74k miles
Symptoms owners cite: Trailer brake engages without cause; Service Trailer Brake warning illuminates; Vehicle becomes unsafe to drive
Codes mentioned: Service Trailer Brake Control Module indicator
Repairs/costs cited: Owners report only workaround is to power cycle vehicle off and back on for temporary relief.
Recalls/TSBs owners mention: Campaign 14V614000 addresses electrical system; some owners report GM bulletin 14515B referenced but VIN exclusions prevent coverage.
Idle control instability with stalling
Engine idles erratically with RPM needle fluctuating between 0.7 and 0.6, or stalls completely at idle in Park or Drive with brake applied. Uncontrolled surges occur when engine restarts after stalling.
When: Reported at 15k miles in police fleet vehicle; recurring after multiple engine calibration updates
Symptoms owners cite: Near complete stalling at idle in Park; Stalling at idle in Drive with brake applied; RPM needle erratic movement; Uncontrolled idle surge upon throttle application; Uncontrolled forward lunging
Codes mentioned: Engine calibration updates applied (hot weather surge/sag)
Repairs/costs cited: Multiple engine calibration updates attempted; symptoms persisted within days to weeks of each update.
Acceleration hesitation and lack of power
Engine hesitates or lacks power on both rapid and non-rapid acceleration. Several-second delay during acceleration makes merging into highway traffic unsafe. Reported in police pursuit vehicle where predictable power is critical.
When: Reported at 15k miles in police fleet vehicle; persistent after calibration attempts
Symptoms owners cite: Lack of power during acceleration; Lag response; Several seconds hesitation on rapid acceleration; Several seconds hesitation on non-rapid acceleration; Unsafe for highway merging
Codes mentioned: Engine calibration issues
Repairs/costs cited: Multiple engine calibrations performed without resolving issue.
Random radio restart with dashboard flicker
Radio randomly restarts during driving. Dashboard gauges and instrument panel flicker on and off intermittently.
When: Multiple occasions during driving
Symptoms owners cite: Radio spontaneously restarts; Instrument panel flickers on and off; Dashboard gauges unstable
Repairs/costs cited: Power cycling vehicle provides temporary relief.
Airbag warning light cycling with other electrical failures
Airbag warning light flashes on and off intermittently in conjunction with other electrical system failures, door locks, and warning lights.
When: During driving; intermittent occurrences
Symptoms owners cite: Airbag light flashing on and off
Service Engine warning light intermittent illumination
Service Engine light illuminates multiple times but cannot be replicated by dealer diagnostics.
When: Multiple occasions; failure mileage unavailable
Symptoms owners cite: Service Engine warning light illuminates
Repairs/costs cited: Dealer unable to replicate failure during diagnostic scan.
Recalls/TSBs owners mention: Campaign 14V614000 issued; part availability delayed, preventing timely repair.
Starting failure with multiple warning light cascade
Vehicle fails to start on some occasions. When vehicle does run, multiple warning lights cycle on and off. Battery tested good by dealer.
When: Intermittent occurrences; recurring pattern
Symptoms owners cite: No-start condition; Door locks open and close rapidly when running; Service Trailer Brake warning illuminates; Low Battery warning cycles on and off; Airbag light flashes on and off
Repairs/costs cited: Battery and alternator tested okay by dealer despite low battery warnings. Dealer unable to replicate problem.
Wipers, cruise control, and brake light sensor failures
Multiple accessory and safety-critical systems fail including wipers, cruise control, and brake lights. Sensor failures reported.
When: Timing not specified
Symptoms owners cite: Wiper system malfunction; Cruise control failure; Brake light failures; Sensor issues
Traction control and stability system false activation
Traction stability control illuminates and cycles off intermittently without corresponding wheel slip or traction loss conditions.
When: Intermittent occurrences
Symptoms owners cite: Traction Stability indicator comes on and off
