Specs side by side
What owners say
Acadia
Overall
Sentiment is sharply divided by generation and is heavily influenced by powertrain reliability. For the 2024+ redesign (2025-2026 model years), owner sentiment is cautiously positive, praising its spacious interior, comfortable ride, modern features (especially Super Cruise and advanced tech on Denali trims), and improved third-row space. However, this is tempered by recurrent reports of significant reliability issues in early production units, including transmission problems and oil leaks.
Best version to buy
For the 2024+ generation, the Denali trim is frequently mentioned as the preferred version for maximizing feature content, including Super Cruise, a digital rearview mirror, heads-up display, massage seats, and advanced parking assist. However, there is no strong consensus recommending lower trims for better value, as the high feature content is a primary draw.
Known issues
- **Engine failures (3.6L V6): ** Catastrophic failure due to oil pickup tube clogging and cam failures, particularly in 2010-2015 models around 80,000-100,000 miles. Frequency: very frequent for older generations.
- **Transmission failures: ** Complete transmission failure reported around 100,000 miles on a 2017 model; transmission issues and "known transmission problems" cited as a deal-breaker for 2017-2023 models; early reliability issues with the 2…
- **Oil leaks/cooler failures: ** Recurrent issue described as the vehicle "weeping oil like BP in the Gulf"; oil cooler failure leading to coolant contamination and overheating in a 2024+ model. Frequency: recurrent.
Telluride
Overall
Mixed to positive sentiment overall, with a clear generational divide. The Telluride is widely praised for its spacious and functional third row, high-quality interior materials, boxy and attractive exterior styling, strong value proposition, and comprehensive standard features. The naturally aspirated 3.8L V6 engine is frequently cited as a mature, reliable, and simple powertrain, especially when compared to newer turbocharged or hybrid alternatives.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim. Discussions mention various trims (SX, EX, Calligraphy) without a clear, repeated preference for one over another.
Known issues
- Engine oil consumption: reports of excessive oil consumption requiring top-ups between changes and, in isolated cases, engine replacement. Frequency: recurrent.
- Underpowered 3.8L V6 engine: described as lethargic, slow, lacking responsiveness, and struggling with acceleration compared to turbocharged rivals. Frequency: very frequent.
- Dealer/service department problems: poor customer service, difficulty getting warranty repairs approved, lack of respect for customers, and general service quality concerns. Frequency: very frequent.
