- What to inspect
- Shift into Drive, then firmly back into Park. Turn off the ignition and check the dash for the warning. Wiggle the shifter knob to see if the message clears.
Engine / ValvetrainHigh
Distinct metallic rattling noise from the engine bay upon cold start, indicating timing chain wear or tensioner slack.
- Typically appears
- 70,000-100,000 miles
- What to inspect
- Ensure the engine is completely cold. Open the bonnet, start the engine, and listen closely to the front timing cover area for a sharp metallic rattle before oil pressure builds.
Body / InteriorMedium
Water ingress causing damp carpets, stained headliners, or a musty cabin odour due to leaking roof rail mounts or sunroof drains.
- Typically appears
- 3-5 years
- What to inspect
- Press the front and rear footwell carpets firmly to check for dampness. Inspect the headliner edges around the sunroof and roof rail mounting points for water tide marks.
Body / TailgateLow
Power boot lid opens partially and falls back down, or groans loudly during operation due to failing gas struts or motor issues.
- Typically appears
- 40,000-70,000 miles
- What to inspect
- Operate the power tailgate using the key fob. Watch for smooth operation to the top of its travel. Apply slight downward pressure to ensure the struts hold the weight.

Build my inspection planFrequently asked questions
Is the Traverse reliable?
Average — the 9-speed automatic and electrical gremlins are the main concerns.
What are common Traverse problems?
Transmission shudder, Stabilitrak warnings and AC faults.
Is the 3.6 V6 strong?
It's capable; earlier GM 3.6 engines had timing-chain wear, so check service history.
Does the second-generation Traverse suffer from the same timing chain issues as older models?
The 3.6-litre LFY V6 in the second-generation Traverse features an updated timing chain design, making it far more robust than the notoriously fragile first-generation units. However, chain stretch can still occur if previous owners neglected routine servicing. Always check the service history for regular, high-quality oil changes to ensure longevity.
What should I look out for regarding the all-wheel-drive system?
The Traverse uses a twin-clutch AWD system that requires specific fluid maintenance. During a test drive, listen for whining from the rear differential and feel for binding or juddering during tight, low-speed manoeuvres. If the rear differential fluid has not been changed at correct intervals, the clutch packs degrade prematurely.
Are there any specific interior wear points to check before retailing?
The infotainment screen can suffer from delamination or phantom touches, so test all touchscreen corners thoroughly. Additionally, inspect the second-row captain's chairs; the sliding mechanisms frequently jam due to debris in the runners. Ensure both seats slide and fold flat smoothly, as repairs often require complete runner replacement.
