Overall
Sentiment is mixed and heavily dependent on model year and powertrain. For older models (circa 2000-2019) equipped with the 6.0L gasoline V8 and corresponding transmissions (e.g., 6L90), owner feedback is overwhelmingly positive regarding long-term reliability, simplicity, and durability, especially when compared to problematic systems like Active Fuel Management (AFM) in lighter-duty trucks. These trucks are described as workhorses capable of high mileage with proper maintenance.
Best version to buy
Based on consensus, the best version is an older model (approximately 2015-2019) 2500HD or 3500HD equipped with the 6.0L gasoline V8 and the 6L90 transmission. This combination is repeatedly praised for its lack of complex cylinder deactivation technology (AFM/DFM), proven reliability, mechanical simplicity, abundant parts availability, and ease of repair.
Known issues
Overall
Sentiment is sharply divided by generation. For the second-generation Tundra (approximately 2007-2021), particularly those equipped with the 5.7L V8, sentiment is overwhelmingly positive, characterized by extremely high praise for reliability, longevity, and robust towing capability. These trucks are frequently described as "bulletproof," with owners reporting trouble-free ownership over many years and high mileage.
Best version to buy
For the second generation, the CrewMax cab is very frequently recommended for its exceptionally spacious and comfortable interior, deemed perfect for families. The 5.7L V8 is the unequivocally preferred engine.
