Buick Enclave (2008–2012): what actually fails

The documented failure patterns on used Buick Enclaves — the mileage window where each shows up, and what the repair typically costs at an independent shop. This is the same data NoLemon's Brief checks against every VIN.

2008–2012 TYPICAL 80k–160k MI $2,000–$3,800

Transmission wave-plate & timing chain (shared platform)

The Enclave shares the Acadia/Traverse platform and inherits both headline failures: the 6T75 wave plate (lost reverse) and 3.6 chain stretch. Verify both in records; a one-owner example with dealer history is worth paying up for.

BEFORE YOU BUY
Ask for repair records covering this item. If it hasn't been addressed and the car is in or near the mileage window, price the $2,000–$3,800 repair into your offer — or make it the seller's problem.
