2018 Chevrolet Traverse problems: what's documented, what to check
No widespread, year-specific problem is documented for the 2018 Chevrolet Traverse. That makes the individual car's history — not the model year — the thing to judge.
Known Chevrolet Traverse issues to ask about
- 2009–2012 3.6L V6: timing chain stretch; listen for cold-start rattle and check for codes P0008/P0017
- 2009–2013 6-speed automatic: 3-5-reverse wave plate failure, often appearing first as delayed or lost reverse
- 2018–2020: start/stop system complaints, low-speed shudder reports, and infotainment glitches; mostly software-addressable
- All years: verify transmission fluid was actually serviced; many never were
Verify these on the specific car
- Cold start listen for chain rattle (first generation)
- Reverse engagement from cold and warm
- Transmission fluid service history
- Check engine light history and stored codes
Treat first-generation Traverses as guilty until proven documented. The 2018+ trucks, and especially 2021+, turn the Traverse into the value play it always promised to be.
