Buick FAQ

Do you service the Buick Enclave?

Yes — all Buick models including all generations of Enclave for all maintenance and repairs.

What maintenance does a Buick Enclave need?

Oil change every 5,000–7,500 miles, transmission fluid every 45,000 miles, and timing chain inspection at 100,000+ miles — the 3.6L V6 is known for timing chain issues at higher mileage.

Why is my Buick making a rattling noise?

Rattling on cold start on the 3.6L V6 Enclave or LaCrosse usually indicates timing chain tensioner wear. This is a known issue and should be inspected before further engine damage occurs.

Do you service Buick turbocharged engines?

Yes. We service all Buick engines including the 1.5T and 2.0T turbocharged four-cylinders in the Encore GX and Envision.
