The Chevy Tahoe is a heavy-duty body-on-frame SUV with proven LS-family V8s. The best used years are 2017-2019 when the K2XX platform was fully sorted before the 2021 redesign brought 10-speed teething problems.

The L83 V8 with the post-update 8-speed automatic is the most reliable combination of the K2XX generation. AFM lifter risk remains but is manageable with regular oil changes and an AFM disabler.
More on this issue →Active Fuel Management lifters collapse and damage the camshaft. Symptoms: ticking on startup, P0300/P0307 misfires. AFM disabler module is the proven preventative.
More on this issue →Shift shudder and harsh 1-2 shifts. GM Bulletin 18-NA-355 covers a fluid flush with Mobil 1 ATF. Most cases resolve after the flush.
More on this issue →Clicking sound from dashboard and temperature stuck on one side. Replacement of the actuator behind the glove box. Aftermarket part is about $30.
More on this issue →Liftgate sags or fails to hold up. Strut replacement is straightforward.

The 2017-2019 Tahoes are the best used years. The K2XX platform was mature, the 8-speed calibration was sorted, and complaint volume is the lowest of the modern era.
Yes, it is the most reliable modern Tahoe. AFM remains a known risk but with an AFM disabler the L83 V8 is bulletproof.
It is the riskiest recent year. The all-new T1XX platform brought 10-speed shudder, infotainment crashes, and independent rear suspension recalls. Wait for 2022-2023.
A maintained Tahoe with the L83 5.3L V8 commonly reaches 250,000 miles. AFM lifter condition is the primary lifespan limit.
Active Fuel Management deactivates cylinders for fuel economy. It is the root cause of lifter collapse on 5.3L Vortec engines. An AFM disabler module ($150-250) is cheap insurance.
Yes. NHTSA 19V-863 (brake booster vacuum pump) and 22V-021 (steering column) are open on some 2017-2021 trucks. Check VIN at nhtsa.gov.
