Pros & cons

Rear-wheel-drive balance with available all-wheel drive on four-cylinder and V6 models.
Upscale, well-built interior with more standard features for the money than German rivals.
Strong, refined engines including a 420-hp 3.6L twin-turbo V-Sport that reaches 60 mph in under 5 seconds.

Cons

Tight rear seat and a small trunk for the midsize-luxury class.
Rear-differential reliability concerns and expensive out-of-warranty repairs.
CUE infotainment is unintuitive and laggy, with reported screen delamination and a class-action complaint.
