What stands out
No new NHTSA powertrain 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 powertrain 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 bulletin provides information on Policies Applicable to All U.S. Dealers for Engine and Transmission Assembly Replacement Under Warranty, Policy or Customer Enthusiasm and information on Submission of Warranty Transaction in Global Warranty Management.
full bulletin at NHTSA ↗This service bulletin provides information on some vehicles that may rock or move slightly forward or rearward while in Park at start up after cold soak. This condition may be accompanied by a clunk noise. This is a slight movement that is more often seen visually, rather than felt, when viewed from the outside and using the auto-start feature, if equipped.

The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

The failure pattern owners describe
Owners of 2011 GMC Yukons describe serious powertrain failures and electrical chaos. Early on, stalling episodes occur at highway and city speeds with no stored trouble codes; dealerships run diagnostics and find nothing, leaving owners stranded without answers or fixes. Two separate engine failures are reported—one replacement unit already dead by April 2025 with zero compression in a cylinder; another cylinder exploded catastrophically with metal fragmentation after a misfire repair missed the root cause.
Throttle body and TPS problems trigger sudden power loss, violent shaking, and limp mode at highway speeds; dealerships eventually replace the throttle body or TPS, though owners suspect the fix is cosmetic. A transmission quits at 60,000 miles and again during city driving; a dealership pins blame on transmission computer failure causing pump and torque converter breakdown. Electrical gremlins plague another owner for over a year—door locks cycling on their own, gauges jumping, and theft-control lockout preventing starts—battery and alternator replacement doesn't fix it. One owner mentions active class-action litigation against GM for engine failures in this generation.

Failure modes owners describe
Engine stalling and electrical instability
Multiple reports of engine dying at speed or idle with no stored diagnostic codes. Owners report alternator/voltage gauge fluctuations, dashboard pops/clicks, and multiple stall-restart cycles. Dealership diagnostics show no codes or abnormality.
When: Early ownership (reported at 2-14 days after delivery in one case); one case during highway driving at 65 mph; another during city speeds
Symptoms owners cite: Engine shuts off without warning; Multiple stall-restart cycles; Voltage gauge needle bouncing erratically; Pop or click sound in dashboard; No stored diagnostic trouble codes
Repairs/costs cited: Dealership ran full diagnostics and reported 'nothing wrong with vehicle/operating normally'; no repairs performed
Recalls/TSBs owners mention: GM case file opened but minimal assistance offered beyond referral to dealership; dealership suggested owner continue driving until problem recurs
Engine failure and loss of compression
Engine replacement performed in 2022 has already failed by April 2025 with complete loss of compression in cylinder 4. Owner reports this is the second engine failure on the vehicle and suspects the replacement engine was known to be defective before installation.
When: Replacement engine installed 07/2022; failed 04/12/2025 while driving at 65 mph on highway
Symptoms owners cite: Engine failure while driving on highway; No compression in cylinder 4; Vehicle undriveable
Repairs/costs cited: Previous engine replacement cost approximately $7,000 in 2022; second replacement quoted at approximately $8,000
Recalls/TSBs owners mention: Owner references ongoing GM litigation regarding engine failure linked to lifters or cams in this model year
Throttle body / TPS induced power loss with warning codes
Sudden loss of power accompanied by multiple warning lights (Stabilitrac, traction control, check engine). Engine power reduced 16% per DIC readout. Cleared after throttle body or TPS replacement, though owner notes similar issue affects 2010 model variant and reports hundreds of complaints on GM forums.
When: Reported 1/24/2013 service date; one case during highway driving
Symptoms owners cite: Sudden loss of power while driving; Stabilitrac system warning illuminates; Traction control warning illuminates; Engine power reduced 16% (per DIC); Check engine light; Rough engine running after restart; Difficulty exiting highway
Codes mentioned: Check engine light codes (cleared by dealer)
Repairs/costs cited: Dealer replaced throttle body assembly and/or TPS; fuses checked; codes cleared. Owner reports friend's 2010 variant required throttle body replacement for same issue
Recalls/TSBs owners mention: No TSB or recall mentioned; owner expresses concern GM is not fixing root cause
Cylinder misfire progressing to catastrophic engine failure
P0305 code for cylinder 5 misfire replaced with coil pack, but cylinder subsequently exploded with catastrophic engine failure 3 months later, throwing metal chunks and destroying the engine block. Owner cites active class-action lawsuit against GM for 5.3L and 6.2L engine failures.
When: Coil pack replaced 10/20/2020; cylinder 5 exploded 01/17/2021 while stationary in parking lot
Symptoms owners cite: Misfire code P0305 (cylinder 5); Cylinder 5 catastrophic failure with metal fragmentation; Loud noise from engine; Complete engine destruction
Codes mentioned: P0305
Repairs/costs cited: Coil pack on cylinder 5 replaced; no underlying cause addressed. Catastrophic failure rendered engine inoperable
Recalls/TSBs owners mention: Owner references active class-action lawsuit regarding high failure rate on 2010–2014 GM vehicles with 5.3L and 6.2L engines
Electrical system instability and battery/alternator failure
Widespread electrical malfunctions including door locks cycling on/own, gauge fluctuations, dimming and resetting of all electrical systems, engine shutdown, and theft-control limp mode. Owner replaced battery and alternator without resolving the core issue. Problem reported for over one year and worsening.
When: Ongoing for approximately one year, progressively worsening
Symptoms owners cite: Door locks lock/unlock involuntarily while driving; All electrical systems dim and reset repeatedly; Gauges moving erratically; Vehicle turns itself off; Engine wants to turn on by itself while stopped at traffic light; Key sometimes won't turn over when trying to start; Theft control warning appears and prevents engine cranking; Vehicle locks itself when parked
Codes mentioned: Theft control mode
Repairs/costs cited: Battery replaced; alternator replaced. Issue persists despite these components
Stabilitrac and throttle body limp mode during highway driving
Engine light and Stabilitrac warning illuminate during highway driving at speed, power dramatically reduced, violent shaking makes it difficult to safely exit highway. Message directs driver to check throttle body assembly. Same issue reported on owner's second vehicle (2014 GMC Yukon XL).
When: During highway driving at 60 mph
Symptoms owners cite: Engine light illuminates; Stabilitrac message displayed; Power to engine dramatically reduced; Car shakes violently; Difficult to exit highway safely; Secondary message to check throttle body assembly; Nearly struck from behind
Codes mentioned: Check engine light
Transmission defect at moderate mileage
Transmission failure around 60,000 miles with initial symptom of rear-end bump sensation when braking. Dealership minimized issue as normal behavior. Separate report of complete transmission failure requiring tow-in; dealership attributed fault to transmission computer failure causing internal pump failure and torque converter malfunction.
When: At approximately 60,000 miles; another transmission failure during city driving (vehicle stopped at traffic light)
Symptoms owners cite: Bump sensation from rear when coming to stop; Complete transmission failure (no forward/reverse engagement); Vehicle immobile at traffic light
Repairs/costs cited: First report: no repair details provided. Second report: transmission computer failure identified as root cause; internal pump failure and torque converter malfunction noted
Recalls/TSBs owners mention: Dealership attributed transmission computer issue to model/year/engine combination (noted as known fault for this configuration)
Transmission dipstick tube breakage
Transmission dipstick tube breaks easily while vehicle stationary. No further details provided.
When: While vehicle was stationary
Symptoms owners cite: Transmission dipstick tube breaks
