Like all GM vehicles, the Cruze has no head restraint in 2C – making it unsuitable for adults or kids in backless boosters due to the risk for severe whiplash injuries. There is a significant bump at the seat crease in 2C – and a less prominent one in 2D & 2P – which will make proper installation of many car seats (especially rear-facing infant seat bases) and booster seats impossible as they won’t rest properly against the back of the vehicle seat.
