🎯 Negotiation ammo — walk in knowing this
Free. The seller won’t volunteer any of it.
- ✅ Verify this recall: Airbag bracket recall (side curtain airbag fasteners) — check recall completion. Make the seller prove it’s been done — an open recall is money off the price.
- 💸 Budget for this: Full transmission failure — won't engage reverse, stuck in gear, pressure control solenoid codes (P0846/P0776 common) — $3,500–$5,500 if it goes. Check it on the test drive; if it’s near due, negotiate it down.
- 🧾 Your opening line: “2018 Chevrolet Traverses 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
2019 Traverse RS or High Country (post-first-model-year running changes, updated TCM software from the factory) with the 3.6L V6 and full service records showing a transmission fluid/filter change — avoid the very first 2018 build run if possible.
🚫 Avoid
An early-build 2018 base LS/LT with no service history and no evidence of a TCM software update — highest concentration of unresolved 9-speed shudder complaints.
