The failure pattern owners describe
Buyer takeaway: The 2024 Traverse has serious transmission and brake issues appearing in the first few thousand miles, including fluid leaks, sudden loss of acceleration in traffic, and complete brake failure. Multiple owners report no warning signs before catastrophic failures, creating dangerous situations that could have caused accidents.
The 2024 Traverse shows a pattern of transmission failures occurring very early in ownership. Transmission fluid leaks appear across multiple vehicles starting at 1,017 miles, sometimes with insufficient bolt torque at assembly. Some leaks offer no warning lights before pooling underneath the vehicle.
Sudden loss of acceleration in traffic is the most dangerous complaint. Owners describe engine revving but zero forward motion, with "Reduced Acceleration" warnings appearing during merges and highway exits. One owner at 103 miles got a check engine light and couldn't shift properly; another lost all power while pulling onto a highway. Clutch piston failure can prevent any movement from a stop. Transmission shift jerking and slipping occur intermittently, with dealers dismissing these as normal "learning phases."
Brake failures are equally serious. One owner experienced complete brake loss during rush hour; another reported brake failure alongside ESC, traction control, lane assist, and power steering failures all at once. The reverse automatic braking system unexpectedly slams vehicles into park with no obstruction behind them.
A coolant leak from the upper radiator hose developed on one vehicle with only 18,000 miles. Owners report no advance warning before transmission or brake failures, making these failures particularly hazardous in traffic. Multiple vehicles sit at dealerships waiting for parts on national back order.

Failure modes owners describe
Transmission fluid leaks
Transmission fluid leaking from bolts, seals, or the housing itself. In some cases, bolts were found to be insufficiently torqued at assembly. Fluid loss can be silent with no warning lights initially.
When: 1,017 to 38,000 miles
Symptoms owners cite: Puddles of transmission fluid under vehicle; Reduced acceleration capability; No warning lights in early stages
Repairs/costs cited: Transmission bolts retorqued; full transmission replacement required in some cases
Recalls/TSBs owners mention: Case numbers opened; no assistance offered in some instances; warranty coverage disputed in others
Sudden loss of acceleration / limp mode
Engine and transmission enter a protective limp mode reducing power to near zero, triggered by transmission faults or thermal issues. Occurs suddenly with little or no advance warning. Creates dangerous situations in traffic.
When: 103 miles to 5,200 miles
Symptoms owners cite: Engine revs but vehicle will not accelerate normally; Check engine light and 'Reduced Acceleration. Drive with Care.' message appear; Vehicle speed drops dramatically or ceases; No prior slipping or rough shifts; Loss of acceleration while merging or in traffic
Codes mentioned: P0746
Repairs/costs cited: Transmission repair or replacement under warranty; parts on national back order
Recalls/TSBs owners mention: Service bulletin released May 14 for transmission #N242446290; warranty repair authorized
Clutch piston failure
Clutch piston internal failure prevents normal torque transmission to wheels. Vehicle does not move or moves only very slowly when accelerating from stop. No warning light until after failure occurs.
When: Unknown; early ownership
Symptoms owners cite: Vehicle does not move when accelerating from stop; No warning light initially; service engine light comes on after a few miles; Very slow acceleration after failure; Sudden failure with no prior indication
Repairs/costs cited: Clutch piston replacement required; parts unavailable at time of complaint
Recalls/TSBs owners mention: GM aware of problem per owner documentation; vehicle sold despite known issue; no parts available
Transmission shift jerking and slipping
Transmission exhibits intermittent jerking, rough shifts, or slipping sensation during acceleration or when transitioning between steady speed and acceleration. Dealer attributes to normal 'learning phase,' but owners report this is not typical in their experience.
When: Early ownership
Symptoms owners cite: Big jerk when putting into drive and accelerating; Transmission feels like it is slipping; Loud noise like transmission is 'dropping'; Jerking when re-accelerating after coasting; Intermittent; difficult for dealer to replicate
Repairs/costs cited: Dealer claims no fix available; dismisses as normal learning phase
Inability to shift / transmission locked
Transmission becomes completely unresponsive. Vehicle cannot be shifted out of park, will not move into any gear, or will not downshift. Vehicle becomes immobilized in traffic.
When: Unknown
Symptoms owners cite: Vehicle stops in middle of street; Cannot shift out of park; Cannot engage any gear; Message 'transmission needs service' appears; Vehicle becomes stuck and immobilized
Repairs/costs cited: Tow truck required; repair details not specified
Unexpected downshifting
Transmission downshifts abruptly and without driver input. Can cause sudden speed reduction and audible engine noise.
When: Around 500 miles
Symptoms owners cite: Unexpected downshift at various speeds; No warning prior to event; Abnormal banging sound from engine after downshift; Occurs without driver command
Repairs/costs cited: Front drive axle was replaced but did not resolve issue
Recalls/TSBs owners mention: Case number provided; no further assistance offered
Reverse automatic braking system malfunction
Reverse automatic braking system unexpectedly engages, slamming vehicle into park when there is nothing behind it. Creates sudden and startling jolt to occupants.
When: Early ownership
Symptoms owners cite: Vehicle slams into park while reversing; Occurs when nothing is behind the vehicle; Sudden jolt that startles occupants; Repeats on multiple occasions
Repairs/costs cited: Dealer states no fix available; recommends disabling the feature
Upper radiator hose coolant leak
Upper radiator hose develops a leak, causing coolant loss. Defective original part. Leak can worsen rapidly, leaving vehicle without coolant reserves.
When: After approximately 18 months; under 20,000 miles
Symptoms owners cite: Coolant leaking from upper radiator hose; Puddle of coolant on driveway; Rapid fluid loss within 48 hours
Repairs/costs cited: Hose replacement required; part on back order; owners advised to monitor coolant level
Recalls/TSBs owners mention: Dealer confirms defective part; warranty repair; parts on national back order
Brake master cylinder failure
Brake master cylinder fails, resulting in complete brake failure. Vehicle cannot stop in normal manner. Creates severe safety hazard during traffic situations.
When: Unknown; early ownership
Symptoms owners cite: Complete brake failure during approach to intersection; Vehicle cannot stop normally; Brake failure alert pops up on dashboard; Brakes appear to recover temporarily after engine restart but issue persists
Repairs/costs cited: Brake master cylinder replacement; 30-day wait for parts
Multiple brake and stability control faults
Brake system, electronic stability control, traction control, lane assist, and power steering all fail simultaneously during normal driving, resulting in complete loss of braking ability and vehicle control.
When: 14,872 miles
Symptoms owners cite: Sudden brake failure at 32 mph; ESC fault indicator; Traction and stability control fault; Brake system fault indicator; Lane assist fault; Power steering fault; Air conditioning failure (blowing hot air); Vehicle nearly collided with traffic
Repairs/costs cited: Not specified
Engine banging noise after shutdown
Abnormal banging sound coming from engine compartment immediately after vehicle is turned off. Cause not determined.
When: Around 500 miles

My 2024 Chevy Traverse is leaking coolant within the radiator hose system. While driving on a busy interstate, the vehicle went into protective limp mode reducing acceleration, creating a dangerous situation for myself to manage. A check engine light did come on with the reduced acceleration notice. I am having to add coolant to the vehicle constantly to drive it. Parts on our national back order…
The contact owns a 2024 Chevrolet Traverse. The contact stated while driving at various speeds, the check engine warning light illuminated on the instrument panel. The vehicle was taken to several dealers and the contact was informed that the issue was related to the OnStar feature. The contact called OnStar but was informed that the App was not responsible for the check engine warning light…
With only 1017 miles on vehicle, the transmission leaked all of the fluid out. Incident happened on a side street, thankfully not on the freeway as this would have been even more of a safety concern. Vehicle was sent to local dealership for inspection. NO warning lamps or messages appeared before, during or after the transmission fluid leaked out of the vehicle.
