Recalls & safety

Pros & cons
Pros
- Good fuel economy for a luxury SUV (around 26 mpg combined), helped by the 48V mild-hybrid from 2020.
- Quiet, upscale, well-finished cabin that feels a class above many rivals.
- Smooth, punchy 2.0L turbo four with strong real-world acceleration.
- Comfortable, composed ride with confident handling.
- Strong brand desirability and resale value.
Cons
- Some early cars suffer brake squeal.
- Requires premium fuel and carries high insurance costs (roughly 2,400 dollars a year).
- Mercedes brand reliability is below average, and repair costs run high (around 1,039 dollars a year, well above the luxury-midsize-SUV average).
- The 2020-2021 M264 mild-hybrid engine has documented cylinder-head and valve-seat failures, sometimes at low mileage.
- Reports of the panoramic sunroof spontaneously shattering.
- Early-year infotainment is dated and fiddly (no touchscreen before 2020, COMAND learning curve).
