🎯 Negotiation ammo — walk in knowing this
Free. The seller won’t volunteer any of it.
- 💸 Budget for this: 2.4L Ecotec (LE9/LEA/LTG) timing chain stretch/failure — chain, guides, and tensioners wear prematurely, sometimes snapping outright and destroying the engine — $1,500–$6,000 if it goes. Check it on the test drive; if it’s near due, negotiate it down.
- 🧾 Your opening line: “2016 GMC Terrains have known issues around this mileage — here’s my number.” Milo’s full report hands you the market price and a line-by-line offer script.

Which one to get — and which to avoid
✅ The one to get
A 2016 Terrain SLT-2 or Denali with the 3.6L V6 (RPO LFX), AWD, and full dealer service records — the V6 sidesteps the timing chain/oil consumption saga entirely and the extra trim level usually means a more pampered previous owner.
🚫 Avoid
Any 2.4L 4-cylinder Terrain with spotty maintenance records or unknown oil-change history — this is exactly the combination that shows up in the timing chain failure complaints.
