Full-size SUVs are among the most expensive family vehicles one can own. With so much riding on these important vehicles, reliability is always a top priority. It also plays a big role in determining our list of the best SUVs.
Many owners use these brutes to tow long-distance, haul materials, and in their business. Breakdowns and time out of service can be a big problem.

Who Provided the Data for This List?
Our evaluation of the largest SUVs on the market uses two primary sources of reliability data.
First, we check out RepairPal. They do a very exacting breakdown of reliability by model and model year that we find helpful. In our rankings, we average the past few years’ ratings to come up with a number between one and five, with higher being better.
Next, we look at the J.D. Power Vehicle Dependability Study. This study evaluates the reliability of three-year-old models by asking owners how many problems they have had in that time. A lower score here is better.
Last, we take a peek at CarComplaints, just to be sure no new, high-volume failures are starting to emerge.
Most Reliable Full-Size SUV Comparison
| Model | RepairPal Score | J.D. Power Score Dependability |
| Lexus LX | ||
| Toyota Sequoia | ||
| Chevrolet Suburban/Tahoe | ||
| GMC Yukon | ||
| Cadillac Escalade | ||
| Ford Expedition | ||
| Nissan Armada |
*Limited data available due to low volume.
1. Lexus LX & Toyota Land Cruiser
The Lexus LX is the premium version of the Toyota Land Cruiser. While the brand sells relatively few of these vehicles, they are known by owners as indestructible.
By comparison to some of its peers, the LX isn’t exactly a trendsetter with cutting-edge technology. Perhaps that’s one reason it doesn’t break?

Our hands are starting to hurt from tapping out the praises of Toyota’s many reliable models.
Let’s say that the Sequoia is a version of the two vehicles above and call that good.

3. GM - Suburban, Tahoe, Yukon, Escalade
Built in the same plant from mostly the same parts, the full-size behemoths from GM all slot in nicely between the highly-reliable Toyota/Lexus family and the also-rans. The Suburban, Tahoe, and Yukon have slightly better scores than the Escalade earns.
These beefy GM machines make up a substantial portion of the full-size SUV market. The Arlington Texas plant has been building these SUVs for decades, and GM knows how important reliability is to these high-profit machines. Look closely, and you will see that the few problems reported are minor.

4. Ford Expedition
The Explorer is so good and so big, it’s hard to believe that Ford needs a bigger model. For those blue-oval fans who do want their SUV super-sized, the Expedition is the answer.
The Expedition earns a reliability score of 3, which is far from impressive, but not the worst case scenario. With Ford’s J.D. Power score being well below the industry average, we placed Ford in fourth.
If money is not a concern and you want an Expedition with slightly better ratings, check out the Lincoln Navigator.
Current Ford Expedition Deals & Incentives
| Year | Make | Model | Cash Incentives (up to) | Best Avail. APR | Lease Offers | Expiration |

| 2024 | Ford | Expedition | $5,000 | 1.90% | $709/month for 36 months, $7,209 due at signing | 1/2/25 |

5. Nissan Armada & Infiniti QX80
Like most brands here, Nissan and Lincoln sell two vehicles via different brands that are basically the same vehicle. We like the Nissan Armada and Infiniti QX80 most among the large SUVs available today, but we have to follow the reliability data, and that puts these vehicles last.
If you are looking for a vehicle on this list, perhaps the Ford Explorer, Hyundai Palisade, or Kia Telluride, please check out our list of the most reliable midsize SUVs. There is no firm line in the sand where midsize ends and full-size begins, and we grouped those vehicles with the midsize SUVs.

What Is the Most Reliable Full-Size SUV?
The top three models and brands in this segment all earn respectable scores for reliability. However, the Lexus LX rises to the top of all the data sources we check. GM’s family of three brands and four models also deserves a mention.
