Starting in 2016, the Malibu is available as a Hybrid (as well as the 100% gas model).
The VERY large bump at the bight, coupled with seat belts and seat belt buckles that are located significantly forward of the bight will interfere with a proper installation of many car seats. It is likely that most infant seat bases will not install securely as the very large bump at the bight will prevent the base from making contact with the back of the vehicle seat, as it needs to do for a secure installation. Backless boosters will also be problematic in this vehicle as there is a gap of several inches between the back of the vehicle seat and the start of the booster – which will create an awkward seating surface for the child and make them more likely to slouch (and slouching is dangerous as it puts the lap belt on the belly, not on the strong hip bones.
2013 saw a change to the lower anchors where 2D and 2C share a lower anchor – again, the vehicle is best thought of as having functional lower anchors for 2D and 2P only.
2004 saw the introduction of a shoulder belt for 2C and 6 lower anchors instead of 4… but because of how they are overlapping with one another in 2D and 2C this vehicle functions as having just 4 lower anchors (a pair for 2D and a pair for 2P).
2002 saw the introduction of lower anchors. This model year range has only a lap belt for 2C.
