The Chevrolet Traverse is a three-row family crossover that competes with the Ford Explorer and Honda Pilot. It’s a popular choice for Oklahoma families needing space and capability in a mid-size package. Like any vehicle, the Traverse has specific known issues that vary by generation. At Norm’s Auto Clinic in Coweta, we’ve serviced many Traverses and can help owners understand what to watch for and when to service it.

First Generation Traverse (2009–2017) — Known Issues

- 3.6L V6 timing chain failure: The first-gen Traverse used the GM 3.6L DOHC V6, which has a complex timing chain system that is highly sensitive to oil changes. With extended drain intervals, the chain guides and tensioners wear, causing a rattling sound on startup and eventually jumping timing. Full timing chain replacement on the 3.6L is a major job — ,200–,000. Prevention: full synthetic oil, change every 5,000–6,000 miles religiously.
- Transmission cooler line failure: The transmission cooler lines on 2009–2012 Traverses can develop cracks at the connection points, causing ATF leaks and eventual transmission damage. Watch for red fluid spots under the vehicle near the front.
- Catalytic converter failure: The rear catalytic converters on first-gen Traverse tend to fail at 80,000–120,000 miles, triggering a P0430 code. The front cats last longer.
- Water pump failure: Like the Equinox 2.4L, some Traverse models had issues with internal water pump seals leaking into the engine oil. The 3.6L uses an external water pump that fails more conventionally — watch for coolant loss.
Second Generation Traverse (2018–Present) — Known Issues
- 3.6L V6 timing chain (same concern): The 2018+ Traverse uses the Gen V 3.6L — still timing chain sensitive. Oil change discipline is the same: full synthetic 0W-20, every 6,000–7,000 miles.
- 9-speed automatic transmission: The second-gen Traverse uses a 9T50 9-speed automatic. Shift hunting between gears and occasional rough shifts have been reported. Software calibration updates and fluid quality both affect shift behavior.
- AC compressor failure: In Oklahoma’s summer heat, the Traverse AC compressor can fail prematurely — often around 80,000–100,000 miles. Annual AC system inspection before summer helps catch low refrigerant and compressor wear early.

Traverse Maintenance Schedule
- Every 5,000–7,000 miles: Oil and filter change (full synthetic 0W-20); tire rotation
- Every 20,000–30,000 miles: Air filter; cabin filter; brake inspection; check all fluid levels
- Every 45,000–60,000 miles: Transmission fluid; coolant condition check; spark plugs (60,000-mile iridium plugs)
- Every 100,000 miles: Coolant flush; full suspension inspection; oxygen sensor assessment; timing chain inspection
