The failure pattern owners describe
Buyer takeaway: Multiple 2025 Traverse owners report transmission fluid leaks and transmission failures at very low mileage (500–4000 miles), with some customers stranded on highways and vehicles out of service for weeks awaiting parts. Uncontrolled RPM surges, slipping transmission behavior, and inability to shift gears compound safety concerns that may warrant a recall.
Eleven owners of 2025 Chevrolet Traverse models describe powertrain issues, with transmission problems dominating the complaints. Six owners report transmission fluid leaks at very low mileage—between 500 and 4,000 miles. Owner #2 found a large puddle of reddish-pink fluid at 2,200 miles; a dealer identified two pump bolts backing out, with parts unavailable from GM until late February. Owner #6 cites GM Service Bulletin 25-NA-001 (dated 3/13/2025) addressing transmission fluid leaks near the torque converter, requiring 13.7 hours of labor. Owner #10 had multiple transmission pump bolts found loose.
Three owners experienced unintended RPM surges to redline while driving at highway speeds, accompanied by sudden loss of power and inability to shift gears—dangerous situations that could have ended in collisions. Owner #2 and #3 report transmission slipping and erratic shifting. Owner #1 describes severe, resonant booming sounds tied to specific RPM and speed ranges that sound like a semi-truck bearing down. Owner #8's transmission needed a valve body replacement at just 500 miles. Owner #9 dealt with coolant pump failure and overheating. Owner #11 reports vibration when reverse is engaged. Multiple owners note vehicles have been in dealerships for weeks without parts availability or repair completion.

Owner #2 cites bolts backing out of the pump; owner #6 references GM service bulletin 25-NA-001 (Transmission Fluid Leak Near Torque Converter, dated 3/13/2025) and confirms dealer/GM involvement; owner #10 reports trans pump bolts found loose by dealer.
When: Owner #2: 2200 miles; Owner #4: ~3000 miles; Owner #5: 3600 miles; Owner #6: After 100-mile trip; Owner #7: 1700 miles; Owner #10: 4000 miles
Symptoms owners cite: Reddish-pink transmission fluid puddle under vehicle; Fluid sprayed from under car (owner #5); Undercarriage and rear covered in transmission fluid (owner #5); Check engine light illuminated; Reduced speed and traction warnings; Loss of motive power at highway speed; Vehicle cannot shift into drive or reverse
Codes mentioned: Check Engine Light, Reduced Speed and Traction warning, GM Service Bulletin 25-NA-001 (Transmission Fluid Leak Near Torque Converter)
Repairs/costs cited: Owner #2: Two bolts backing out of pump; parts unavailable from GM until late February (as of mid-January); Owner #6: 13.7 hours labor per GM; Owner #10: Multiple transmission pump bolts found loose; Owner #7: New transmission needed. Vehicles have been in shops for weeks without parts availability.
Recalls/TSBs owners mention: GM Service Bulletin 25-NA-001 issued 3/13/2025 addressing transmission fluid leak near torque converter (per owner #6). Multiple owners note parts on backorder from GM.
Transmission slipping and erratic shifting
Owners #2 and #3 report transmission slipping and erratic gear behavior. Owner #2 describes acceleration feeling like tires slipping on ice followed by jerks. Owner #3 reports erratic shifting, gear hesitation, and sporadic power loss. These occur at low mileage on nearly new vehicles.
When: Owner #2: 2200 miles; Owner #3: 2–3 months after purchase
Symptoms owners cite: Acceleration feels like tires slipping on ice; Jerks during acceleration; Erratic shifting; Gear hesitation; Sporadic power loss while driving; Delayed acceleration when merging into traffic; Unexpected gear disengagement at speed
Repairs/costs cited: Owner #2: Transmission leak also found; repair pending parts. Owner #3: Vehicle at dealership for nearly three weeks with no updates or diagnosis completed.
Uncontrolled RPM surge and loss of power at highway speeds
Owners #4, #7, and #10 report sudden, unintended engine RPM spikes to redline while driving at highway speed, accompanied by loss of motive power. Owner #4's RPM revved to red zone at 70 mph without pedal input. Owner #7 experienced RPM spike to 6000 at 70 mph with 1700 miles on odometer. Owner #10 had sudden loss of power at highway speed with transmission unable to engage. All three situations created dangerous traffic conditions.
When: Owner #4: ~3000 miles; Owner #7: 1700 miles; Owner #10: 4000 miles
Symptoms owners cite: Unintended RPM surge to red zone / 6000 RPM; No accelerator pedal input at time of failure; Loss of motive power at highway speed; Vehicle cannot engage drive or reverse gear after event; Check engine light illuminated; Reduced speed and traction warning
Codes mentioned: Check Engine Light, Reduced Speed and Traction warning
Repairs/costs cited: Owner #4: Vehicle not yet diagnosed or repaired at time of report; transmission fluid puddle found. Owner #7: Transmission failure; new transmission needed; transmission fluid under car. Owner #10: Transmission fluid leak and multiple transmission pump bolts found loose; repair took almost 3 weeks.
Resonant booming / whomping noise under load at specific speeds / RPM
Owner #1 reports a severe resonant booming or whomping sound that occurs at specific highway speeds and RPM ranges, tied to transmission gear and RPM. Sound is described as extremely loud, panic-inducing, and seemingly emanating from chassis or powertrain. Does not occur at lower speeds. Owner notes all windows up, AC on, no obvious loose items. Suggests possible design flaw in chassis or powertrain.
When: Owner #1: 19500 miles on rental vehicle; occurs at 54 mph, 60 mph, and 72–77 mph depending on RPM and transmission gear
Symptoms owners cite: Loud whomping/booming resonant sound; Sound frequency tied to specific RPM and transmission gear; Sound increases in intensity at highway speeds; Occurs at 54 mph, 60 mph, and 72–77 mph; Sound subsides when vehicle slows down or changes RPM/gear; No obvious loose parts found after inspection
Repairs/costs cited: Owner performed visual inspection of tires, undercarriage, engine bay; found nothing obviously loose or hanging. Issue persisted across multiple acceleration attempts.
Transmission valve body failure and reverse-gear lockout
Owner #8 reports check engine light and warning message indicating vehicle cannot be put in reverse due to unsafe condition after only 13 days of ownership and 500 miles. Dealership diagnosed a faulty valve body requiring replacement.
When: Owner #8: 500 miles, 13 days of ownership
Symptoms owners cite: Check engine light; Warning message: vehicle cannot be put in reverse due to unsafe vehicle condition; Vehicle cannot shift into reverse
Codes mentioned: Check Engine Light
