What stands out
No new NHTSA cruise control complaint has been filed on this vehicle in over 8 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering cruise control 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 Preliminary information communicates direction and examples when diagnosing multiple DTCs, one of which includes U**** Byte 71 DTC.

The failure pattern owners describe
Owners of 2015 Chevrolet Traverses describe two primary failure patterns: unintended acceleration and unexplained power loss.
Unintended acceleration incidents range from sudden full-throttle surges during low-speed parking maneuvers to progressive acceleration during highway driving. In one case, cruise control refused to disengage despite the driver pressing the button and braking multiple times; a third hard brake finally worked. Another owner accelerated from 5–10 mph to full speed in a parking lot from barely touching the gas pedal, crashing into a building. A third lost control from 2 mph and hit a barn. In a separate incident, the vehicle bucked violently from a traffic light, then accelerated to 50–60 mph; the brake pedal slowed it only temporarily before the vehicle surged back to speed.
Power loss events occur during normal driving at various speeds. The engine suddenly drops power, accompanied by check engine lights, stability control warnings, and traction control messages. Some vehicles enter limp mode. One owner experienced this three times; each incident cleared itself overnight. Repairs have included purge valve replacement, spark plugs, coils, and accelerator pedal sensor replacement, yet failures recurred. One independent mechanic attributed the issue to carbon buildup in the throttle body, calling it a flawed system, though dealers denied this and could not reproduce the failures.

Failure modes owners describe
Unintended acceleration with cruise control malfunction
Vehicle accelerates on its own while cruise control is engaged; brake pedal and cruise control button fail to disengage the system on first attempts. Owner must apply hard braking multiple times to regain control.
When: 60 mph on interstate entrance ramp
Symptoms owners cite: vehicle accelerates despite foot off gas pedal; shuddering when braking; cruise control button does not disengage on first attempt; continued acceleration after initial braking
Sudden full-throttle acceleration from low speed
Vehicle revs up and accelerates at full speed from a gentle pedal input, causing loss of control and collision. Occurs during low-speed maneuvering in parking lots.
When: parking lot at 5-10 mph; 39,700 miles
Symptoms owners cite: vehicle accelerates to full speed from light pedal pressure; brake pedal fails to engage properly; violent acceleration; total loss of control
Repairs/costs cited: cosmetic repairs performed by independent mechanic
Power loss and unintended deceleration with warning lights
Engine power drops suddenly during highway and city driving; vehicle may decelerate to 25 mph or stall; check engine light, stability control, and traction control warnings display. Issue recurs even after repairs.
When: various speeds; as early as 12k miles (leased vehicle); up to 67,206 miles
Symptoms owners cite: sudden power loss while driving; engine speed drops; vehicle jarred forward then loses power; popping sound from engine; check engine light illuminates; stability trac warning; traction control off message; engine power reduce message; limp mode activation; vehicle shaking
Codes mentioned: purge valve error code (replaced but did not resolve)
Repairs/costs cited: purge valve replaced; spark plugs and coils replaced; accelerator pedal sensor replaced on multiple occasions by independent mechanic; independent mechanic cited carbon buildup in throttle body as cause
Recalls/TSBs owners mention: dealer unable to reproduce failure; no codes found on subsequent diagnostics; manufacturer notified once but no assistance offered; dealer denied carbon buildup issue
Bucking and shaking with subsequent uncontrolled acceleration
Vehicle bucks and shakes during acceleration from standstill, then accelerates rapidly to 50-60 mph with loss of throttle control. Braking initially slows vehicle but it surges back to speed.
When: from traffic light at low speed
Symptoms owners cite: bucking and shaking from takeoff; excessive rapid acceleration follows bucking; loss of throttle control; brakes slow vehicle temporarily then vehicle surges back up; dashboard lights flashing
Sudden unintended acceleration from near-stop
Vehicle accelerates rapidly on its own from near-zero speed (2 mph), resulting in collision. Total loss of vehicle; no diagnostic follow-up performed.
When: 2 mph; 18,000 miles
Symptoms owners cite: rapid unintended acceleration from near-stop; complete loss of control
Repairs/costs cited: vehicle towed and destroyed

What owners are reporting 1 most recent
I was originally in a parking lot, stopped completely, then proceeded to gently turn left in to a parking space. I barely pushed the gas pedal and the car revved up and took off full speed ahead making me crash in to a hill. The hill is a small landscape space that divides the parking lot and a busy 6 lane street. The front of the car was damaged. I was completely shocked yet thankful this did…

At what mileage does the cruise control typically fail?
Across the 8 complaints that reported odometer mileage, most cruise control failures cluster between 34,500 and 66,500 miles, with the median around 48,130. A quarter of owners report trouble before 34,500; a quarter make it past 66,500. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $600 for cruise control repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to cruise control?
No active recalls currently cover cruise control issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
