GMC Service FAQs

How do I schedule a GMC service appointment online?

You're already there. Just fill out the appointment form on this page with your vehicle details (year, make, model, and VIN if available), select your preferred date and time, and choose the service(s) you need: oil change, tire rotation, brake inspection, etc. You'll get a confirmation once it's submitted. If you don't see a time that works, call our service department directly at (888) 310-1453.

How long does an oil change take at Moss Bros. GMC?

Most oil changes take 30 to 60 minutes if you're waiting, though wait times can be longer during busy periods or if we identify additional maintenance your vehicle needs. We recommend scheduling an appointment for the fastest service.

Do you offer a shuttle service while my car is being serviced?

Yes. If your service is going to take a while, just let your service advisor know when you check in and we'll arrange a shuttle to take you home or to work, and pick you back up when your vehicle is ready.

What are your service department hours?

Our service department is open Monday through Friday from 7:00 AM to 5:30 PM and Saturday from 7:00 AM to 5:00 PM. Sundays, we are closed.

Do I need an appointment, or do you accept walk-ins?

We accept walk-ins for most services, but scheduling ahead helps us have your technician and any needed parts ready, so your visit takes less time.

How much does an oil change cost at a GMC dealership?

With a current service coupon from our GMC Service Specials page, oil changes can start around $79.99 for a 6-quart ACDelco GM Dexos 1 full synthetic oil change. Pricing may vary depending on your vehicle and current specials, so check our Service Specials page or call us for the most up-to-date pricing.

Do you use genuine GM/GMC parts for repairs?

Yes. Our GM-certified technicians use genuine GM/GMC OEM parts for all repairs and maintenance. OEM parts are engineered specifically for your vehicle's make and model, which means a proper fit, consistent performance, and no risk of voiding your factory warranty. This is different from many independent shops, which often use aftermarket parts to cut costs.

How often should I rotate my tires or replace brake pads on a GMC truck/SUV?

We recommend rotating your tires every 5,000 to 7,500 miles, or at every other oil change. This promotes even tread wear and can extend tire life significantly. Brake pad life varies more by driving style and conditions, but most GMC trucks and SUVs need front pads replaced every 30,000 to 40,000 miles and rear pads every 40,000 to 60,000 miles. Towing, frequent stop-and-go driving, or hilly terrain will wear them faster. Your exact intervals may vary based on your specific GMC model and how you drive, so check your owner's manual for manufacturer-recommended intervals, or schedule a free brake inspection with us and we'll let you know exactly where you stand.

What should I do if my check engine light comes on?

First, check whether the light is steady or flashing. A flashing check engine light means a serious issue, like a misfire, that could damage your engine or catalytic converter if you keep driving. Pull over safely and have your vehicle towed or serviced as soon as possible. A steady check engine light is less urgent, but it still means your vehicle's computer has detected a problem, ranging from something minor like a loose gas cap to something more significant like a failing sensor. It's safe to keep driving in most cases, but you should schedule a diagnostic appointment soon rather than ignoring it. Our GM-certified technicians can run a full diagnostic scan to pinpoint the exact cause and give you an accurate repair estimate before any work begins.

Do you offer any current service coupons or specials?

Yes. You can check out our current service coupons at our GMC Service Specials Page. We have coupons for tire rotations, cooling system refreshing, brake installation, oil changes, and more. Our coupons do change every couple of months, so check back frequently to see which specials we're offering.

Can I get my vehicle serviced under warranty here even if I didn't buy it from Moss Bros.?

Yes. Your GM factory warranty is valid at any authorized GM dealership, not just the one where you purchased your vehicle. Whether you bought your GMC truck or SUV from us, another dealer, or even a private seller, our GM-certified service department can perform warranty repairs and maintenance as long as your vehicle is still within its coverage period. Bring in your vehicle's VIN and any prior service records, and we'll verify your warranty status and get you scheduled.
