What Year is The Most Reliable GMC Acadia?

If you’re searching for the most reliable GMC Acadia for your family, you’ve come to the right place. As an owner of a 2013 Acadia for the past five years, I’ve been thrilled with the dependability and trouble-free operation it has provided. This three-row SUV has been perfect for our needs, giving us plenty of passenger and cargo space but without the high repair bills or headaches that often come with less reliable vehicles.


The Most Reliable GMC Acadia

The first generation GMC Acadia debuted in the 2007 model year. As one of the earliest models, the 2007-2009 Acadia had some typical issues that come with being in the first model generation. Common problems included transmission failures, engine problems, and electrical issues.

While not completely unreliable, these early models had more reported issues than later years. If you’re looking at one of these first generation Acadias, it would be best to have a mechanic thoroughly inspect it before purchasing. Overall, the 2007-2009 model years are not considered the most reliable GMC Acadia.

The 2010 model year was the first full redesign of the Acadia. Many of the bugs from the initial 2007-2009 generation had been worked out. Reliability improved, but there were still some issues to watch out for. The 3.6L V6 engine that was used in these model years had a timing chain guide problem that could lead to engine failure if not addressed.

The transmission, while improved, still saw some failures. Other problems included faulty wheel bearings, leaking sunroofs, and electrical gremlins. While better than the first generation, the 2010-2012 Acadia still faced some long-term reliability question marks. Overall, they were moving in the right direction reliability-wise, but had some problems that keep them from being the most reliable GMC Acadia.


The 2013 model year brought the second major redesign of the Acadia. With this redesign came vastly improved reliability. The 3.6L V6 engine was refined and the transmission issues from previous years seemed to be resolved. Common problems became almost non-existent. A few minor issues included brake caliper seizures, sunroof leaks, and faulty cooling fans.

However, these were relatively inexpensive and easy fixes that did not cause long-term reliability concerns. Consumer complaint levels and repair rates dropped significantly compared to earlier model years. Overall owner satisfaction was very high. With few major problems, easy fixes for minor issues, high owner satisfaction, and proven long-term durability, the 2013-2016 GMC Acadia is widely considered to be the most reliable GMC Acadia model years.


The third generation Acadia debuted for the 2017 model year and brought more refinement. Reliability remained very strong, building on the excellent reputation from the previous generation. A new 3.6L V6 and 9-speed automatic transmission were smooth and trouble-free. A new 2.5L 4-cylinder was also an option and had no widespread issues either.

A few minor complaints included faulty third row seats, buggy infotainment systems, and faulty windshield wiper motors. However, these were generally low-cost fixes that did not threaten the long-term dependability of the vehicle. Repair rates remained very low through the 2017-2019 model years. With continued excellent reliability, the third generation Acadias are also considered some of the most reliable GMC Acadia years.

The current, fourth generation Acadia debuted for the 2020 model year. It remains too early to judge long-term reliability. However, initial reports are very positive. The carryover 3.6L V6 and 2.5L 4-cylinder engines, now with new 10-speed automatic transmissions, have proven track records. Early owner feedback has been excellent with few reported issues.

Preventative maintenance will be important as these are new generations of engines and transmissions, but all signs point to the 2020 and up Acadias continuing GMC’s streak of building the most reliable GMC Acadia in recent years. Only long-term ownership will fully prove their dependability, but they seem to be off to a great start.

Final Thought

If you’re looking for the most reliable GMC Acadia, the 2013-2016 model years stand out as having the best track record based on extensive owner experiences and repair history data. They experienced few major issues, easy fixes for minor niggles, and have proven their long-term durability.

The 2017-2019 years are also very strong in the reliability department with an excellent reputation carrying over. And early reports on the 2020+ models suggest they also have potential to be segment leaders in dependability. Overall, any Acadia from the 2013 model year onward should provide years of trouble-free operation and be a solid choice if a no-nonsense, reliable SUV is high on the priority list.


What’s the difference between the 3.6L V6 and 2.5L 4-cylinder engines?

The 3.6L V6 provides more power well-suited for towing, with a strong reputation for longevity often exceeding 200k miles. The 2.5L 4-cyl is more fuel efficient but with slightly less power. Both engines have proven very reliable.

What years had transmission problems and were they serious issues?

Some early models experienced more failures typically related to solenoids or wear. GM addressed this starting in 2013 with transmission improvements. Reports since then have been very positive.

How many miles can I expect to get out of a well-cared for Acadia?

With proper maintenance like in the owner’s manual, the Acadia should last 150k miles or more before major repairs are needed. The 3.6L V6 especially has shown great durability routinely making it past 200k miles.

What major services are recommended and around what mileages?

Follow the manual’s recommendations for tune-ups every 30k miles, timing belt replacement at 90k miles, and fluid changes for transmission at 60k miles and coolant at 100k miles.

What warning signs indicate it’s time to move on from an older Acadia?

Excessive repairs, visible rust, or a slipping transmission may indicate it’s nearing the end. Annual repair bills exceeding $1,000-2,000 also suggest it’s not cost effective to sink more money into an aging high-mileage vehicle.
