“I’ve been having issues with my transmission sensors. Service of my car was great; they listened to my concerns, the symptoms of my car, and were able to confirm the issue and get it finished within the 24-48 hour diagnostic period. Very communicative, kind, personable, and knowledgeable! Mr. Sproat was my point of contact while my car was being serviced here. He was extremely kind and patient! He definitely made my experience great.”

Frequently Asked Questions

Service FAQ


Common questions about scheduling, what’s included, and what to expect during your visit.

What’s the difference between Quick Lane and the Main Service Line?
+

Quick Lane handles fast, routine maintenance — oil changes, tire rotations, brake inspections, batteries, alignments, wiper blades, and similar express services. Walk-ins are welcome and most visits take an hour or less.

The Main Service Line is for everything else: diagnostics, repairs, recalls, GM warranty work, transmission service, electrical issues, and anything that needs a certified GMC technician with deeper diagnostic time.

Do I need an appointment for Quick Lane service?
+

No appointment is required for Quick Lane — walk-ins are always welcome. That said, scheduling above lets us prep your service ticket, pull parts ahead of time, and get you out the door faster, especially during peak hours.

Do you offer loaner vehicles?
+

Yes — for qualifying repairs and warranty work on the Main Service Line, we can arrange a loaner vehicle. Availability depends on the type of service and timing, so let your service consultant know when you book that you may need one.

Will you honor my GM factory warranty?
+

Absolutely. As an authorized GMC and Buick dealer, we handle all GM factory warranty work, recalls, and certified pre-owned coverage. Bring your VIN and we’ll verify your coverage on the spot.

Can you service vehicles other than GMC and Buick?
+

Yes. While we specialize in GMC and Buick, our Quick Lane and Main Service technicians service all makes and models for routine maintenance and most repairs. Bring in your Chevy, Ford, Toyota, Honda, or anything else — we’ll take care of it.

How will I know when my vehicle is ready?
+

Your dedicated service consultant will keep you updated by text or phone throughout the day. You’ll get a call or text once your vehicle has been inspected, when work is complete, and again when it’s washed and ready for pickup.
