Specs side by side
What owners say
Yukon
Overall
Sentiment is sharply divided by generation and model year, with a clear distinction between older and newer vehicles. Feedback on older generations (circa 1995-2014) is overwhelmingly positive regarding long-term durability and mechanical simplicity, with many owners reporting vehicles exceeding 200,000-400,000 miles with minimal major issues. These are frequently described as "beasts that just won't die" with cheap, readily available parts.
Best version to buy
For older models (pre-AFM, circa 2000-2006), the 5.3L V8 (LM7) is highly praised for being "bulletproof." For newer models, the consensus is to avoid the first model year of a redesign (specifically 2021). The 2018-2020 generation is cited as a "sweet spot" where earlier reliability issues were worked out, making it preferable over the 2021+ models.
Known issues
- ⚠Catastrophic engine failure (6.2L V8): Engine seizure and total failure requiring full replacement, specifically noted in 2025 models despite assurances issues were fixed. Frequency: very frequent.
- ⚠Active Fuel Management (AFM/DOD) system failure: Lifter failure leading to destroyed camshafts and engine damage in 5.3L and 6.2L V8s (2015-2024+ models). Frequency: very frequent.
- ⚠Drivetrain shuddering/vibration: Persistent shaking, especially around 15-50 mph (24-80 km/h), unresolved by multiple dealer visits involving tire, wheel, motor mount, and differential replacements. Frequency: very frequent.
Discovery
Overall
Sentiment is sharply divided and heavily dependent on the specific generation and powertrain. Long-term owner reports express deep affection for the vehicle's unique character, unparalleled off-road capability, luxurious comfort, and commanding driving position. Many describe it as a favorite vehicle that is a delight to drive, with exceptional ride quality that isolates occupants from road imperfections.
Best version to buy
Insufficient owner data available to declare a single "best" version across all generations. For the Discovery II (1998-2004), the Td5 diesel engine is frequently mentioned as a reliable and capable choice, especially with a manual transmission for towing.
Known issues
- ⚠Catastrophic crankshaft failure (TDV6/SDV6 diesel engines): Sudden engine seizure, described as a widespread manufacturing defect and critical safety issue. Frequency: very frequent.
- ⚠General poor reliability / frequent breakdowns: Multiple, varied failures requiring recovery, including timing chains, brake lines, radiator hoses, and coolant systems, often at low mileage. Frequency: very frequent.
- ⚠Electrical gremlins: Persistent minor electrical faults, warning lights, and system malfunctions that are expensive to diagnose. Frequency: recurrent.
