2025 Chevrolet Traverse Problems: 4 Known Issues

On the 2024-2026 Chevrolet Traverse 2.5L Turbo I4 LK0, gM issued Preliminary Information bulletin PIP6102 in February 2026 (revised to PIP6102A in March 2026) covering unexpected engine stalling on 2024-2026 Traverse, Acadia and Enclave models built with the turbocharged 2.5L LK0 four-cylinder paired to the MF8 eight-speed automatic. A Preliminary Information bulletin is not a recall — GM states the cause is still under investigation by engineering and is suspected to be related to the torque converter, which means owners bringing a stalling third-generation Traverse to a dealer may be told nothing is wrong if the specific conditions are not reproduced. The bulletin describes a stall after a remote start or after the engine has idled to warm up, on the first shift into drive or reverse, in ambient temperatures below 32°F (0°C), with no DTCs stored, which makes the condition hard to duplicate on a test drive.

On the 2024-2026 Chevrolet Traverse, third-generation Traverse owners report the forward collision system alerting and the automatic emergency braking system applying the brakes with no obstacle present — on open highway, over bridge joints, and past roadside objects. One NHTSA complainant documented more than sixty phantom collision warnings and roughly ten self-braking events. The rear automatic braking system produces the same behavior in reverse, which GM acknowledges in information bulletin 24-NA-048 as design sensitivity of the rear virtual bumper, with no calibration fix. Related driver-assist faults (Super Cruise and adaptive cruise dropping out) are acknowledged in GM preliminary information with no released fix. A vehicle that brakes itself in traffic is a rear-end collision risk, which is why this pattern is drawing both NHTSA complaint volume and plaintiff-firm attention.

On the 2024-2026 Chevrolet Traverse 2.5L Turbo I4 LK0, the third-generation Traverse's 2.5L turbocharged four-cylinder LK0 uses plastic quick-connect fittings at the radiator hoses instead of conventional clamps. Owners report the connector at the upper radiator inlet hose weeping and then losing coolant well inside the warranty period — a class action filed in 2026 covering 2024-2026 Traverse, 2024-2026 Acadia and 2025-2026 Enclave with the LK0 alleges the fittings fail prematurely and let the engine run without adequate coolant. Documented consequences run from a low-coolant lamp and a P3075 code through reduced power/limp mode to overheating damage. GM has since extended special warranty coverage on the radiator inlet hose quick connect. This is a third-generation-only issue and shares nothing with the V6 water pump leaks of earlier Traverses.

On the 2009-2025 Chevrolet Traverse, the Traverse power liftgate struts lose gas pressure over time, causing the liftgate to drop slowly when opened or slam shut unexpectedly. On models with power liftgate, the electric motor can also fail, leaving the liftgate inoperative via the button. The struts typically fail between 5-8 years, with cold weather accelerating the failure as the gas charge loses pressure faster at low temperatures. A dropping liftgate is a safety concern, especially when loading cargo or with children nearby.
