    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.

    This issue also affects: Buick Encore GX, GMC Canyon

    Common Symptoms

    • Low coolant warning message
    • Coolant smell or residue at the upper radiator hose
    • Coolant puddle under the front of the vehicle
    • Check engine light
    • Reduced engine power / limp mode
    • Rising temperature gauge

    How to Fix

    Treat any low-coolant message on an LK0 Traverse as a leak, not evaporation — pressure test the system cold and inspect the upper radiator inlet hose quick connect specifically, where the residue is usually visible as dried coolant around the collar. The repair is replacement of the hose and quick-connect assembly with the updated part. GM's special coverage runs five years/60,000 miles from the original in-service date and transfers with the vehicle, so check the VIN before paying. If the engine has already been operated hot, have the cylinder head and gasket evaluated before assuming the hose fix ended the matter.

    On the 2024-2026 Chevrolet Traverse 2.5L Turbo I4 LK0, gM issued Preliminary Information bulletin PIP6102 in February 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 fix — it is GM instructing dealers to capture data because the root cause is not yet identified, which means owners bringing a stalling third-generation Traverse to a dealer may be told nothing is wrong. Reports describe stalls at low speed, during deceleration and at stops, with the engine restarting normally afterward, which makes the condition hard to duplicate on a test drive.

    Common Symptoms

    • Engine stalls at low speed or when coming to a stop
    • Stall on deceleration
    • Engine restarts normally after stalling
    • Loss of power steering and brake assist during the stall
    • No stored codes / dealer unable to duplicate

    How to Fix

    There is no released repair at the time of writing. The correct step is to have the dealer open a case under PIP6102 so the vehicle's data is captured and submitted to GM engineering — this both protects the owner's warranty record and contributes to the eventual remedy. Before accepting 'no trouble found', ask the technician to pull and preserve freeze-frame data and any history codes, and to confirm the vehicle has current ECM/TCM calibrations, since stall complaints on this powertrain are also being addressed through software. Owners with repeated stalls should document each occurrence in writing; in states with lemon statutes a repeated unrepaired stall is a strong claim.

    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 addressed with a calibration bulletin. 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.

    Common Symptoms

    • Brakes apply on their own with no obstacle present
    • Forward collision alert with nothing ahead
    • Sudden deceleration on the highway
    • False rear automatic braking when reversing
    • Adaptive cruise or Super Cruise disengaging unexpectedly

    How to Fix

    Have the dealer verify the front camera and radar are correctly aimed and calibrated — a windshield replacement or minor front-end repair without recalibration is a common trigger and is worth ruling out first. For false triggers while reversing, request the rear automatic braking calibration update in TSB 24-NA-048. Keep the sensor apertures in the grille and windshield clean and free of aftermarket film or badges. If phantom braking continues after calibration, file a complaint at nhtsa.gov/report-a-safety-problem with dates and locations — complaint volume is what drives an investigation on a system with no current remedy. Forward collision sensitivity can be reduced or the system switched off in vehicle settings as an interim measure.

    On the 2018-2024 Chevrolet Traverse, the moonroof feeds rainwater into a rain tray above the headliner that drains through tubes routed down the pillars. Debris clogs the tubes (and tray outlets), so the tray overflows and water runs down the inside of the headliner, dripping from the overhead console, dome/map light area, or near the rearview mirror. Second-generation (2018-2024) and earlier owners report soaked headliners, wet front floors, and damaged overhead electronics. Some cars also have poorly seated/kinked or leaking quick-connect drain hoses that leak even after the tubes are cleared.

    Common Symptoms

    • Water dripping from headliner or overhead console
    • Wet front carpet / floor mats
    • Water near rearview mirror or dome light
    • Musty/mildew smell
    • Fogged interior glass

    How to Fix

    Clear the moonroof drain tubes with low-pressure air/water from the top (avoid high pressure that can pop hoses off). Verify hose routing and reseat/replace kinked or disconnected drain hoses and leaking quick-connect couplings; in severe cases the sunroof drain assembly is serviced. Dry the headliner to prevent mold.

    Typical repair cost:$150 - $1,700

    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.

    This issue also affects: GMC Yukon XL

    Common Symptoms

    • Liftgate drops slowly when opened
    • Liftgate slams shut unexpectedly
    • Have to hold liftgate up manually
    • Power liftgate button does not work
    • Liftgate opens only partway in cold weather

    How to Fix

    Replace both liftgate struts as a pair ($50-$120 for a pair of gas struts). This is a simple DIY repair — the struts have ball-socket ends that pop off with a small pry tool (15-minute job). For power liftgate models, if the electric motor has failed, the motor assembly costs $200-$500 and requires 1-2 hours of labor to replace. StrongArm and Sachs/Stabilus are quality aftermarket strut brands. Always replace both struts at the same time — they wear at the same rate.

    On the 2018-2025 Chevrolet Traverse, the second-generation Traverse (2018+) uses the GM 9T65 9-speed automatic transmission that suffers from a shudder during light acceleration in the 25-50 mph range. The torque converter clutch chatters during lockup, producing a vibration that feels like driving on a rumble strip. The 9-speed also exhibits harsh downshifts, hunting between gears on hills, and delayed engagement from Park. GM has released multiple TCM software updates to address the shifting behavior, but the underlying torque converter weakness remains.

    This issue also affects: Buick Enclave, Buick Encore GX, Buick Regal

    Common Symptoms

    • Shudder or vibration at 25-50 mph under light throttle
    • Harsh downshifts when coasting
    • Transmission hunting between gears on hills
    • Delayed engagement from Park to Drive
    • Hesitation on acceleration from low speeds

    How to Fix

    Start with a dealer visit for the latest TCM software calibration — GM has released numerous updates that improve 9-speed behavior. A full transmission fluid exchange with Mobil 1 LV ATF HP (DEXRON HP specification) can significantly reduce or eliminate the shudder. If both steps fail, the torque converter needs replacement ($1,500-$2,500 including labor). Some owners have had success with a complete transmission replacement under warranty. Change the 9T65 fluid every 45,000 miles as preventive maintenance.
