Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine 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 provides information on replacing the intake manifold when the engine is replaced after severe internal engine damage.

The failure pattern owners describe
Owners of 2024 Chevrolet Traverses are reporting multiple distinct engine-related failures. Coolant system problems dominate the complaints: radiator hoses (upper and lower) are leaking without warning lights, causing complete coolant loss and overheating on the highway. Several owners note the parts are on backorder with no ETA. One owner's radiator failed at 15,000 miles with no available fix from Chevrolet.
Power loss during normal driving shows up in multiple reports—sudden loss of acceleration at highway speeds and a loss of power when driving through wet conditions. One owner experienced complete engine shutdown at 65 mph on the interstate; after a catalytic converter replacement, the shutdown recurred.
Oil pump failure locked up the engine at 3,333 miles on one vehicle; the engine, oil pump, and turbo were replaced. Two weeks after repair, the replacement engine made shuttering noises and required a second engine replacement at 3,450 miles.
Check engine lights are persistent across reports, with diagnostic codes including P3075 (Engine Cooling System error). One owner brought the vehicle in four times in under a year for check engine light and critical malfunctions, with a 28-day service stay for a loss-of-acceleration issue. Another vehicle failed an emissions test without a diagnosed cause.

Failure modes owners describe
Radiator and coolant hose leaks
Upper and lower radiator hoses and radiator leaking coolant, often with no warning lights. Owners discovering puddles underneath the vehicle or finding coolant reservoir empty. Hoses and radiators failing without visible external damage or connection-point leaks.
When: As early as 3,900 miles; reported at 15,000-18,000 miles; some reports at higher mileage without stated mileage
Symptoms owners cite: Coolant pooling under vehicle; Climbing temperature gauge; Cooling fans running at full speed; Engine overheating; No warning lights or low-coolant alerts; Radiator leaking from top right area
Codes mentioned: P3075
Repairs/costs cited: Upper radiator hose replacement, lower radiator hose replacement, complete radiator replacement, coolant system refill. Parts reported on backorder until late December/January with no ETA in some cases.
Recalls/TSBs owners mention: Owners report on social media that this issue is typical of 2024 model year Gen 3 Chevy Traverse. No recall issued as of complaint dates.
Loss of acceleration and engine shutdown
Vehicle loses acceleration suddenly or shuts down completely while driving, often at highway speeds. Pressing accelerator produces engine rev with no forward motion. Restarting may be required multiple times. Issues recur after repair attempts.
When: Early in vehicle life; 3,900 miles noted in one case; incidents at various mileages without specific odometer readings in others
Symptoms owners cite: Sudden loss of acceleration; Engine shutdown while driving 65 mph on interstate; No forward motion despite engine revving; Check engine light illuminated; Vehicle stranded in roadway; Failure recurred after catalytic converter replacement
Codes mentioned: <UNKNOWN>
Repairs/costs cited: Catalytic converter replaced; repair did not resolve issue. One instance required 28-day shop stay; underlying cause not resolved in multiple cases.
Recalls/TSBs owners mention: Manufacturer opened case after notification. Repair attempts (catalytic converter replacement) failed to resolve recurring shutdown.
Oil pump failure and engine replacement
Oil pump failed and locked up the engine early in vehicle life, requiring complete engine replacement. Replacement engine developed shuttering noises within two weeks, necessitating a second engine replacement.
When: 3,333 miles for initial failure; 3,450 miles for second failure (17 miles after first repair completion)
Symptoms owners cite: Engine locked up; Shuttering noises from replacement engine; Vehicle immobilized requiring tow
Codes mentioned: <UNKNOWN>
Repairs/costs cited: Engine, oil pump, and turbo replaced. Customer waited 4 months for initial repair. Second engine replacement performed after replacement engine made shuttering noises at 3,450 miles.
Coolant system loss without warning
Vehicle loses large quantities of coolant during normal driving (including highway speeds and wet-condition driving) with no warning lights or low-coolant notifications. Owners unaware of problem until noticing high temperature gauge or forced to stop.
When: Various mileages; one instance at early mileage, others not specified
Symptoms owners cite: Rapid coolant loss; No warning lamps; No OnStar notifications of coolant issue (though one OnStar notification came on late); Temperature gauge climbing; Engine overheating risk; Air conditioning shutoff due to overheat protection
Codes mentioned: <UNKNOWN>
Repairs/costs cited: Lower radiator hose and upper radiator hose replacements; parts on backorder.
Check engine light and multiple diagnostic codes
Check engine light illuminates repeatedly across multiple visits. Owners report multiple warning lights and several diagnostic codes detected. Some codes relate to cooling system; others unspecified.

Emissions test failure without diagnosed cause
Vehicle failed DMV emissions test after radiator/coolant repair. Returned to dealer for diagnosis but no cause found and vehicle was not repaired.
When: 18,000 miles

My car is leaking coolant. There is no warning light or anything. Had to be towed to the dealership. Dealership confirms the truck is not driveable and needs an upper radiator hose which is on backorder until January. There aren't any loaner vehicles according to the dealership.
To date, I have brought the vehicle to the service department four times, primarily due to the check engine light and other critical malfunctions. Below is a summary of the incidents: First Visit (approx July 2024): The vehicle suddenly lost acceleration while I was in traffic, leaving me stranded in the roadway.
