Thinking about buying a Chevy Tahoe but worried about reliability? You’re smart to do your homework. The Tahoe is a staple on American roads, but its reliability record isn’t straightforward. This full-size SUV offers impressive space, strong towing capacity, and undeniable road presence—but how dependable is it really?
According to RepairPal, the Tahoe earns a 3.5 out of 5.0 reliability rating, ranking 21st out of 26 full-size SUVs. That’s slightly better than average for its class, but the story gets more complicated when you look at specific model years and common issues.
Let’s dive into what makes some Tahoes reliable workhorses that cruise past 200,000 miles, while others might leave you stranded with expensive repair bills.
Tahoe Reliability: The Big Picture
What the Experts Say
The Chevy Tahoe receives mixed reviews from major automotive authorities. RepairPal’s 3.5/5 rating reflects moderate reliability, while J.D. Power scores have remained relatively stable over recent years (82/100 for 2018, 81 for 2021, and 83 for 2024).
Consumer Reports takes a more cautious stance, particularly with newer models. They predict the 2025 Tahoe will likely experience below-average reliability compared to other new vehicles, based on data from recent model years and overall Chevrolet brand performance.
Ownership Costs: What to Expect
Be prepared for higher-than-average maintenance expenses if you’re buying a Tahoe. The average annual repair cost is $744—significantly more than both the midsize SUV average ($573) and the all-vehicle average ($652).
Over a 10-year ownership period, Tahoe owners typically spend around $10,028 on maintenance and repairs—$1,820 more than the industry average of $8,208.
There is some good news, though. Tahoes tend to need unscheduled repairs less frequently than other vehicles (0.3 times per year versus the industry average of 0.4). The catch? When problems do occur, they’re more likely to be serious—with a 16% probability of major repairs compared to 12% for all vehicles.
