What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 6 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.

full bulletin at NHTSA ↗This Preliminary Information communication provides information to the technician about vehicles that have an intermittent no crank, no start, or start stall concern with the security light coming on. Technician may find Diagnostic Trouble Codes B3055, B3060, and/or B3935. Technician should not replace any parts for this concern. If unable to duplicate the concern ask if the customer uses any Radio Frequency Identification Devices when the concern is present. Dealer should also direct their customers to the appropriate section in the Owner manuals that references that the device complies.

The failure pattern owners describe
Owners report catastrophic electrical failures happening without warning at highway speeds. The entire electrical system shuts down—engine stalls, power steering quits, brakes lose assist, dashboard goes dark, and every electrical component from door locks to dash lights powers off for 1 to 15 minutes. One owner's vehicle died three times on interstate at 70 mph; another experienced 20+ events over six months.
Multiple owners replaced batteries, battery cables, ignition switches, fuse boxes, and body control modules. Dealer service visits—often 5 or more per vehicle—have failed to identify a cause. GM technicians cannot recreate the problem or pinpoint root cause. Owners note a recall exists for 2015 Tahoe for the same issue, yet the 2010 remains unfixed.
Secondary electrical problems are widespread: doors hold water after rain, corroding speakers and wiring; dashboard pads crack, exposing circuits and wiring near airbags; antenna connections rust and short out. One 2010 arrived with trailer harness wires disconnected at the factory, disabling trailer lights and brakes—warranty was denied.
Owners universally report finding hundreds of others online with identical failure patterns and the same shop-visit frustration.

Failure modes owners describe
Random power loss and electrical system shutdown while driving
Vehicle experiences sudden, complete loss of electrical power while in motion. Dashboard gauges drop to zero, engine stalls, steering becomes hard, brakes become stiff, all electrical components (locks, lights, radio, dash instruments) lose power simultaneously. Vehicle becomes unresponsive for 1 to 15 minutes before power returns. Occurs unpredictably at highway speeds (up to 80 mph) and in low-speed traffic.
When: Throughout vehicle ownership; one owner reported issue recurring every 3-4 months over 3 years; another reported 20+ occurrences over 6 months; 71,212 miles cited in one report
Symptoms owners cite: Complete loss of electrical power while driving; Engine stalls without warning; Dashboard gauges drop to zero or go erratic; Door locks cycle on and off; Radio turns on and off repeatedly; Steering wheel stiffens (loss of power steering); Brakes become stiff (loss of power assist); Warning lights illuminate (ABS, traction control, check engine); Vehicle speed limiter engages—max 5-15 mph until power returns; Transmission jerks or slams into low gear
Codes mentioned: ABS light, Service traction control light, Check engine light, Loss of engine power message
Repairs/costs cited: Owners report replacing battery, battery cables, master fuse, ignition switch, BCM (body control module), and fuse box with no resolution. Multiple service visits (5+ per vehicle) have failed to correct the issue. Mechanics unable to diagnose root cause; GM technicians state they cannot pinpoint the problem or recreate it.
Recalls/TSBs owners mention: Owners report 2015 Tahoe recall exists for this issue but 2010 model not included; service bulletins exist describing exact problem but have not resolved failures. Warranty claim denied in one case (trailer plug wiring). GM has not provided fix despite widespread complaints.
Door water intrusion and electrical corrosion
Water accumulates inside rear door panels after rain, causing rust and electrical damage to speakers, wiring, and door lock mechanisms. One owner reported visible water pooling in doors; another reported water leaking into passenger door causing seat belt dampening.
When: After heavy rain; progressive issue over vehicle ownership
Symptoms owners cite: Water pooling audibly inside rear door panels; Water leaking into passenger door area; Seat belt becomes wet from door water intrusion; Risk of rust formation on internal components
Repairs/costs cited: No repairs described. Owners identify issue themselves after rain events.
Dashboard cracking with exposed wiring
Dashboard pad cracks and splits, exposing internal wiring and circuits to temperature fluctuations and moisture. Cracks documented above speedometer, on passenger side near airbag, and at corner of passenger airbag—creating sharp edges adjacent to airbag deployment zone. Owners report progressive worsening.
When: Occurs during vehicle ownership; described as progressive over time
Symptoms owners cite: Visible cracks in dashboard surface; Exposed wiring and circuits visible through cracks; Progressive crack propagation; Sharp jagged edges at airbag proximity
Repairs/costs cited: GM refused full-cost replacement; owners unable to repair through warranty.
Recalls/TSBs owners mention: GM will not replace dashboard at full cost despite widespread U.S. reports of similar defects.
XM radio antenna and wiring corrosion
XM radio antenna, mounting wires, and antenna box connections behind glove box corrode due to moisture exposure, causing radio short and failure.
When: Time of failure not specified
Symptoms owners cite: XM radio malfunction; Antenna corrosion
Repairs/costs cited: Replacement antenna quoted at $600 by dealer. Owner opted to purchase aftermarket radio and installation from Best Buy instead.
Trailer harness wires disconnected at factory
Vehicle purchased with trailer package; trailer harness wires not connected to fuse box at factory. Trailer lights and brakes inoperative until discovered and corrected. Dealer denied warranty coverage claiming customer should have specified wire connection at purchase.
When: Present from new vehicle delivery
Symptoms owners cite: No power to trailer lights; No power to trailer brakes
Repairs/costs cited: Dealer connected wires at fuse box to restore trailer power.
Recalls/TSBs owners mention: Warranty claim denied; dealer stated wiring connection was customer responsibility despite manual indicating simple plug-in installation.

After heavy rain I noticed that both of my back doors sounded like there was a gallon of water inside of them. I read that this is a very common issue! I can only imagine the amount of rusting happening inside of there as well as electrical damage & risks of having wet speakers & wiring inside the door. Unacceptable. This should be a recall.
