Recalls & safety
Recall history hasn't been loaded for this model year yet.
Whether a recall is still open on a specific car depends on its VIN. Check it free at NHTSA's VIN lookup (nhtsa.gov/recalls), or ask the seller for proof the repair was done.
Pros & cons
Pros
- Engaging, car-like handling and sharp steering that make it feel smaller and more agile than its size.
- Upscale, near-luxury cabin with materials and design a class above most mainstream three-row SUVs.
- Strong low-end torque from the 2.5L turbo (up to 310 lb-ft) for confident merging and passing.
- Above-average reliability rating and a low rate of severe repairs for the segment.
- Handsome styling and strong value compared with luxury-badged three-row crossovers.
Cons
- No hybrid option and only middling fuel economy versus newer three-row rivals.
- Cracked-cylinder-head / coolant-loss engine failures are a real risk, especially on 2016-2018 cars.
- Third row is best left to children and cargo space behind it is tight for the class.
- Early models use a rotary-knob infotainment controller rather than a touchscreen, which some find awkward.
