If you’re shopping for an SUV, reliability is probably near the top of your priority list. GMC is often seen as a more premium alternative to Chevy, but are GMC SUVs reliable?
The short answer: Yes. From the compact Terrain to the full-size Yukon, GMC has built a strong reputation for quality and durability. Below, we dive into expert reliability ratings, long-term ownership experiences, and what real GMC drivers have to say.
Reliability Ratings: What the Experts Say
Third-party reviewers like J.D. Power and Consumer Reports regularly evaluate automakers for dependability, and GMC consistently holds its own. Here’s how each SUV performs:
GMC Terrain
- Compact SUV with solid reliability marks.
- J.D. Power often gives it above-average scores for quality and dependability.
- Owners report few major mechanical issues with newer models, especially post-2020.
GMC Acadia
- Midsize SUV known for versatility and comfort.
- Early generations (pre-2017) had transmission issues, but those concerns have been largely resolved.
- Later models, especially Denali trims, score well in long-term reliability and owner satisfaction surveys.
GMC Yukon
- Full-size SUV that’s built to last.
- One of GMC’s most reliable and longest-lasting models.
- High marks from experts for durability, especially in Denali trim with more refined engineering.
Expert Verdict:
GMC SUVs generally receive strong ratings, with the Yukon standing out as a benchmark for long-term durability. While some earlier models had hiccups, current-generation GMCs are considered dependable by most industry standards.
Long-Term Ownership: Do GMC SUVs Last?
Reliability isn’t just about avoiding issues in the first year—it’s about how a vehicle holds up over time. GMC owners frequently report high mileage achievements with minimal major repairs.
How Many Miles Do GMC SUVs Last?
With proper maintenance, most GMC SUVs can surpass 200,000 miles. That’s especially true for the Yukon and Acadia, which are built on proven GM platforms shared with Chevy Suburban and Traverse models.
Maintenance and Cost of Ownership
GMC SUVs are relatively affordable to maintain. According to RepairPal, average annual repair costs for GMC SUVs fall in the midrange—not the cheapest, but definitely not high for a premium brand.
- Terrain: ~$500/year
- Acadia: ~$550/year
- Yukon: ~$600–700/year
These costs are reasonable for vehicles of their size and class and reflect well on GMC’s build quality.
Key Features That Boost Reliability
GMC doesn’t just rely on brand reputation—it integrates real features that enhance long-term reliability and driver confidence.
GMC Pro Safety
Included as standard on most newer models, this suite of driver-assist features includes:
- Automatic Emergency Braking
- Forward Collision Alert
- Lane Keep Assist
- Following Distance Indicator
These technologies help reduce accidents and wear-and-tear, ultimately improving a vehicle’s lifespan.
Engine & Drivetrain Engineering
GMC shares powertrains with Chevrolet—engines that have been extensively tested and proven across millions of vehicles. This means:
- Fewer early mechanical failures
- Consistent part availability
- Experienced service centers familiar with the platforms
Build Quality
Owners and reviewers often praise GMC for:
- Minimal cabin noise
- Fewer squeaks and rattles over time
- High-quality materials, especially in Denali trims
These details don’t just make for a better ride—they indicate a more durable and well-assembled vehicle.
What Real Owners Say
Beyond expert ratings and specs, the most telling insights come from real GMC SUV owners.
Common Praise Across Models:
- Comfortable, quiet rides: Especially in the Acadia and Yukon
- Dependable performance: Many drivers report little to no issues over years of ownership
- Strong towing capability: Particularly appreciated in the Yukon and Acadia
- Resale value: Denali trims hold value well, thanks to their premium reputation
Example Owner Reviews:
Terrain Owner, 2021:
“We’ve had ours for three years now—absolutely no issues. It drives smooth, and we feel safe in it.”
Acadia Owner, 2020:
“Transmission shifts great, rides super smooth. Better than the Honda Pilot we had before.”
Yukon Denali Owner, 2018:
“It tows like a beast and still rides like a luxury car. Closing in on 150K miles and still going strong.”
Common Concerns (and What’s Been Fixed)
No vehicle is perfect, and GMC has had its share of issues—mostly with earlier models.
- Pre-2017 Acadia: Known for transmission problems, now resolved in newer redesigns.
- Infotainment bugs: Some users have reported software glitches, typically fixed with updates.
- Fuel economy: Full-size SUVs like the Yukon are not the most efficient, but that’s expected in the segment.
Fortunately, most complaints are isolated to older models or base trims. Newer GMC SUVs, especially Denali and AT4 variants, tend to have excellent reliability scores.
Are GMC SUVs Reliable?
Yes—GMC SUVs are reliable, durable, and designed to last. Whether you’re looking at a Terrain, Acadia, or Yukon, you can expect long-term value, low maintenance stress, and a smooth, capable drive.
When properly maintained, GMC SUVs routinely reach 200,000+ miles with minimal major issues. With strong resale value, refined interiors, and proven powertrains, GMC is a smart choice for families, commuters, and adventurers alike.
