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 service bulletin advises the technician to check if the transmission cooler lines are twisted to correct customer concerns of Harsh Shift, Shudder, Surge, Stall, Transmission Overheating and/or High Transmission Fluid Temperature.

The failure pattern owners describe
Owners of 2023 Cadillac Escalades with the L87 engine report sudden, catastrophic loss of propulsion without warning lights or messages. Most happen on highways at speed. One owner lost all electrical control—brakes, steering, dashboard—while carrying children on I-25 in construction traffic. Another stalled in the middle of the road with a dead battery leaving them stranded for six hours. A third experienced the engine stall after completing the L87 loss-of-propulsion recall service itself.
Before total failure, many owners hear abnormal engine noise: ticking, whistling, knocking, or clanging. One owner's lifters failed at 8,600 miles, then again at 21,000 miles despite repair. Dealership technicians confirm abnormal lifter clatter and active misfires on both cylinder banks.
Transmission problems layer on top: slipping, hard downshifts, inability to exceed 50 mph, unintended 4WD engagement, and inability to shift into Park. One owner received a "transmission needs service" message mid-drive.
Engines are failing well under 50,000 miles. Dealers report backordered replacement engines with no ETA and no loaner vehicles. One dealership claimed it cannot perform the mandatory PicoScope diagnostic under the recall because the engine's mechanical failure interferes with testing, yet refused to authorize the covered engine replacement and teardown despite GM's special coverage mandate for exactly this scenario.
Failure modes owners describe
Sudden loss of propulsion / complete power loss
Engine shuts down completely while driving, often on highway at speed, with no warning lights or minimal warning. Vehicle loses all electrical control including brakes, steering, and ability to restart. Multiple owners report being stranded in traffic lanes unable to move or signal.
When: Between 8,600 and 49,000 miles; one incident on I-25 at highway speed; one on residential highway; one on interstate with construction; one after oil change service.
Symptoms owners cite: Engine shuts down completely; Loss of all electrical power; No brake or steering control; Unable to restart engine; Dashboard screens go black; Music still playing but engine won't turn over; Unable to engage hazard lights; Stranded in traffic lane
Codes mentioned: L87 Engine Loss of Propulsion (recall designation)
Repairs/costs cited: Full engine replacement required. One owner reported dealership initially recommended only oil cap replacement and oil change per recall instead of engine replacement. Multiple owners report engines on backorder with no repair timeline. One dealership claimed engine could not be tested due to internal damage.
Recalls/TSBs owners mention: Recall letter issued (one owner received). GM Special Coverage code cited for engine teardown and replacement at no cost when engine cannot be safely tested due to internal mechanical failure within recall population. One dealership refused to authorize work under this coverage, pressuring owner to pay.
Lifter failure / abnormal engine noise (clatter, ticking, knocking, clanging)
Owners report hearing ticking, whistling, knocking, or clanging sounds from engine before catastrophic failure occurs. One owner experienced lifter failure at 8,600 miles requiring repair, then again at 21,000 miles. Dealer confirmed abnormal lifter clatter on both cylinder banks.
When: 8,600 miles (first lifter failure); 8,750 miles (transmission issue); 10,600 miles (spark plug/rough idle); 17,000 miles (hard downshift); 21,000 miles (lifter failure again). One complaint involves noise with no timeline given.
Symptoms owners cite: Ticking sound from engine; Whistling noise; Knocking sound; Loud clanging noise from engine; Rough idle; Active misfires; Abnormal lifter clatter on both banks; No warning lights accompanying noise
Codes mentioned: Lifter clatter, Active misfires
Repairs/costs cited: Lifter replacement at 8,600 miles and again at 21,000 miles. One dealership service advisor advised lifters need replacement yet again but noted hard downshift issue failed to be fully addressed. One owner reports dealer has several 6.2 V8 engines out back waiting for parts with no ETA.
Recalls/TSBs owners mention: GM upper level advised no remedy could be found until service bulletin resolved; directed dealership to release vehicle to customer as-is until engine replacement available. One owner states GM is forcing them to drive vehicle with failing engine due to insufficient replacement engine stock.
Transmission slipping, hard downshift, torque converter failure, valve body malfunction
Transmission exhibits slipping, inability to exceed certain speeds, unintended 4WD engagement, difficulty shifting into Park, and hard downshift events. One owner received service message that transmission needed servicing while driving.
When: Approximately two weeks after initial dealer recall service (first owner); 8,750 miles (torque converter); 17,000 miles (transmission valve replacement for hard downshift); 21,000 miles (same hard downshift issue recurred).
Symptoms owners cite: Transmission slips; Vehicle will not exceed 50 mph; Automatic engagement of 4WD mode; Vehicle gets stuck in 4WD; Hard downshift events; Unable to put transmission in Park; Parking brake cannot be disengaged; Service message on screen: 'transmission needed to be serviced'
Repairs/costs cited: Torque converter replacement at 8,750 miles. Transmission valve body replacement needed. Service advisor at one dealership stated hard downshift failed to be fully addressed after repair. One owner reports valve body issue still unresolved despite multiple service visits.
Recalls/TSBs owners mention: Dealership initially attributed transmission issues to recall or electrical issue without performing full transmission replacement. GM upper level has not provided remedy.
Catastrophic engine failure requiring full engine replacement
Engine experiences complete internal failure requiring replacement. Failures occur suddenly with minimal or no warning. In one case, low oil pressure light came on immediately before engine blew. Most show no warning lights before failure.
When: Less than 28,000 miles; multiple cases between 8,600 and 49,000 miles; one case around 21,000 miles; one after recall service completion at 6,000+ miles.
Symptoms owners cite: Low oil pressure light (one case); Engine shut down / stalled; Engine will not restart; Whistling noise before failure; Knocking/clanging noise before failure; No check engine light or warning prior to failure in most cases
Repairs/costs cited: Full engine replacement required. Dealer confirms catastrophic engine failure. Multiple owners report engines on backorder with extended wait times. One owner's engine awaited parts for extended period. Dealer repairing one vehicle had 'several' 6.2 V8 engines awaiting replacement parts in the lot.
Recalls/TSBs owners mention: Recall issued (number N252494000 referenced in one complaint). One owner reports recall service completed 9/24/25 but engine failure occurred 4/9/26. No timeline or loaner vehicle provided during repairs.
