The failure pattern owners describe
The 2024 GMC Yukon is logging a pattern of severe electrical and powertrain failures. At least six owners report complete engine shutdown while driving highway speeds—some at 70+ mph—without warning lights or symptoms beforehand. The vehicle shifts to neutral, power steering and braking disappear, and restart attempts fail or require multiple tries. One owner's engine suffered catastrophic bearing failure with metal contamination throughout the cooling system. Another's engine stalled immediately after a dealer oil change. A post-Recall 25V-274 engine replacement left the vehicle with low ignition voltage codes and BCM communication failure, still stalling at highway speed.
Transmission shifting to neutral without input has stranded owners in traffic and on shoulders; one customer waited eight days at a dealership only to be told "try again and record it." Battery drain kills new batteries within 24 hours on at least one diesel model. Serial gateway communication errors persist daily despite replacement and reprogramming. Infotainment systems are unreliable—navigation screens go blank, radios freeze, false crash warnings trigger repeatedly, and speed limit displays show wrong values. Audio warnings and radio sound cut out intermittently. One owner reports dealership refusing written documentation of a known misfire issue tied to AFM software, suggesting a 2025 model as the fix. Dealerships often cannot reproduce or diagnose problems, leaving owners stranded or with recurring failures.

Failure modes owners describe
Catastrophic engine stalling at highway speeds
Engine shuts down completely without warning while driving, often at highway speeds (55–75 mph). Vehicle shifts to neutral, loses all power steering and power braking, and becomes a coasting hazard. Restart attempts vary—some succeed after multiple tries, others require system reset or tow truck.
When: Between 5,000 and 46,000 miles; one case occurred immediately after dealer oil change
Symptoms owners cite: Engine cuts off mid-drive without audible or visual warning; Automatic shift to neutral; Loss of power steering and power braking; Check engine light (sometimes only after restart); Dashboard goes dark or flickers; Clicking noises from electrical system; Low oil pressure warning (post-stall); Push-start messages appear
Codes mentioned: P2534 (Low Ignition Voltage), U3018 (BCM Communication), U0285, U1345, 12 unknown codes (battery drain case)
Repairs/costs cited: Full engine replacement required in multiple cases; one case involved bottom-end bearing failure, camshaft seizure, flywheel shear, and metal contamination throughout cooling system and radiator. Dealerships unable to reproduce issues in some cases despite history codes present; one customer awaiting engine replacement with estimated 2-week to 3-month lead time.
Recalls/TSBs owners mention: Recall 25V-274 (6.2L L87 engine); post-remedy failure documented with continued stalling and electrical compromise (P2534, U3018 codes); dealership attempting to charge diagnostic fees for failed recall workmanship
Transmission shift failures and loss of drive
Transmission shifts into neutral without driver input while driving, leaving vehicle unresponsive to shift commands. 'Conditions not correct for shift' error messages appear; some cases require battery disconnect/system reset to restore function.
When: Early operation (one case at <9,000 miles); occurs on acceleration or normal driving
Symptoms owners cite: Automatic shift to neutral mid-drive; Unable to shift back into drive after neutral engagement; Engine won't turn over after shift failure; Error message: 'Conditions not correct for shift'; Repeated recurrence after dealer 'repair'
Codes mentioned: Codes related to shift control (not explicitly named in narratives)
Repairs/costs cited: Dealership unable to reproduce issue in at least one case; customer asked to wait until it happens again and record it. One case required tow truck unable to shift vehicle into neutral for transport. Recurred one week after dealer 'repair'.
Serial data gateway / BCM communication failures
Recurring 'lost connection' or communication errors between vehicle control modules without dash warning lights. Multiple replacement attempts and software reprogramming required; issues persist daily.
When: Early ownership (noted within first few months)
Symptoms owners cite: Lost communication codes daily; No warning lights accompanying errors; Vehicle self-leveling when in gear (unintended lowering); Service rear axle warnings intermittent; Brake control issues tied to communication loss
Codes mentioned: Lost communication / serial data gateway codes (unspecified in detail)
Repairs/costs cited: Dealership replaced serial data gateway and reprogrammed; issue recurred. Second customer with same complaint reports dealer attempting reprogramming of brake control monitor; vehicle continues to have lost connection codes.
Battery drain and electrical system malfunction
Battery fails to hold charge despite replacement. Twelve diagnostic codes unable to be resolved. Occurs on diesel model with <2,000 miles.
When: <2,000 miles; new vehicle
Symptoms owners cite: Battery dies with no warning; Rapid drain after replacement; Multiple restart failures; 12 unresolved diagnostic codes
Codes mentioned: 12 codes (not specified)
Repairs/costs cited: Battery replaced twice; second replacement also failed within 24 hours. Dealership unable to diagnose root cause. Customer pursuing buyback.
Mirror and window control electrical faults
Reverse tilt mirror feature malfunctions, preventing mirrors from returning to normal position. Requires software update to repair.
When: Early ownership (noted within first months)
Symptoms owners cite: Mirrors do not return when switching to drive from reverse; Malfunction clears on restart
Repairs/costs cited: Dealership service required software update to resolve.
Misfire and AFM (Active Fuel Management) disability false triggers
Engine misfires and MIL flashing when coasting downhill or on inclines. Dealership claims software disables 5 cylinders intentionally, causing vibration misinterpreted as misfiring. Dealership refuses to document or resolve, offering new 2025 vehicle as alternative.
When: During normal operation (coasting/hills)
Symptoms owners cite: Engine misfire detected when coasting; MIL light flashing; Excessive vibration on hills
Codes mentioned: MIL misfire codes (specific codes not provided)
Repairs/costs cited: Dealership factory field service tech claims AFM software intentionally disables 5 cylinders; they refuse written documentation and refuse repair, suggesting customer purchase 2025 model instead.
Infotainment and driver-assistance system failures
Navigation screen goes blank, radio freezes or becomes unresponsive, signal indicator sound mutes, speed limit display errors, and false frontal crash/object detection alerts trigger repeatedly.
When: Recurring throughout ownership
Symptoms owners cite: Navigation screen blank with no map data; Radio not responding; screen turns black; Signal indicator sound absent when activating turn signal; Speed limit display shows incorrect speed (e.g., 55 instead of 25); Frontal crash warning ('Frontal Crash Not Available') alerts at least monthly without cause; False object detection alerts during driving; Parking assist not functioning reliably; Screen does not toggle between daylight/nighttime mode; Vehicle randomly brakes citing nearby object when nothing present
Repairs/costs cited: Dealership repairs have been temporary; issues recur after updates. One customer reports screen issues return after dealer repair.
Recalls/TSBs owners mention: Software updates attempted at dealership; issues recur
Audio system and warning signal loss
Radio, OnStar indicator sounds, and audible safety warnings (including pedestrian alerts) intermittently cut out or fail to produce sound.
When: Intermittent throughout operation
Symptoms owners cite: Radio sound drops intermittently; OnStar blinker indication sound absent; Audible safety warnings mute; Pedestrian alert sounds absent
Post-recall engine replacement electrical complications
After full engine replacement under Recall 25V-274, vehicle experiences catastrophic electrical compromise including low ignition voltage, BCM communication failure, sudden power loss, exterior turn signal hyper-flash, and AC system disabled by Body Control Module.
When: Post-remedy (after November 2024 engine replacement)
Symptoms owners cite: Sudden loss of power; Engine stalling at highway speeds; Total failure of exterior turn signals (hyper-flash); AC system disabled due to low voltage; Low ignition voltage condition; BCM communication failure
Codes mentioned: P2534 (Low Ignition Voltage), U3018 (BCM Communication)
Repairs/costs cited: Vehicle fits profile of NHTSA Recall Query RQ26-001 and Engineering Analysis EA25-007. Dealership attempting to charge diagnostic fees to investigate failed recall workmanship.
Recalls/TSBs owners mention: Recall 25V-274 remedy failed to restore safe operating condition
