Chevrolet Traverse owners are flooding social media with reports of cooling-system troubles: crossovers are developing coolant leaks, low-level warnings are lighting up on the dash, and repairs often drag on because parts are hard to come by. Most complaints focus on the 2024 Traverse, the first model year of the third generation, though 2025 and 2026 vehicles also come up.Customers say waits for radiators and hoses can stretch for weeks or even months. Some describe repeat failures: one owner said a dealer replaced a hose after nearly two months off the road, only for the part to fail again almost immediately; they also claimed the vehicle wasn’t taken on a test drive after the repair. Taken together, these stories paint a picture of a fix-and-wait cycle that erodes patience and trust.There is no official service bulletin yet, but General Motors stated it is already working with its dealer network to identify the causes of the “cooling system issue” affecting some 2024–2026 Traverse models. GM notes that dealers can carry out necessary repairs now, while the company is preparing a new bulletin and, in parallel, promises to improve parts availability. That mix of in-progress guidance and pledges to free up components suggests the root cause isn’t fully nailed down, but momentum is building.It’s notable that similar complaints have barely surfaced about the GMC Acadia and Buick Enclave, which are closely related to the Traverse, though that doesn’t rule out comparable cases. For owners waiting on components or dealing with repeat leaks, the key takeaway is that formal repair instructions are on the way and parts supply should accelerate. For a fresh generation, early cooling-system gremlins aren’t unusual; the real measure will be how quickly dealerships turn assurances into consistent fixes.
