The 2026 NX 350h scores a B on everything except LATCH, and the recurring reason is space. Cars.com had to move the front passenger seat forward for the infant seat, leaving a 5-foot-8-inch passenger with legroom described as just barely sufficient. The booster buckles sit flush with the cushion, so kids will struggle to buckle themselves. It does not fit three car seats.

Three car seats across: no. Room for two. Cars.com tested the all-wheel-drive F Sport Handling trim.
Where the anchors are
Lower anchors. Two sets, easy to find and use.
Top tethers. Three midway down the seatbacks, well labeled but sitting under the seatback upholstery, so they take a bit of digging.
NHTSA recommends always using the top tether with a forward-facing car seat, whether it is installed with the lower anchors or the seat belt, as long as both the car seat manufacturer and the vehicle manufacturer permit it. Check both manuals for your specific combination, and check your car seat's tether weight limit: NHTSA directs you to stop using the tether once your child exceeds it, even while they still fit the seat. Our car seat safety guide covers how to use it.
Infant car seats
Easy to install, but the front passenger seat had to move forward slightly. Legroom for the 5-foot-8-inch front passenger was just barely sufficient, and Cars.com noted taller passengers will need more.
That matters more than it sounds. In a lot of compact vehicles a rear-facing seat pushes the front passenger forward until the front row is unusable. Browse the infant car seats we carry, and if you are weighing whether a rotating base is worth it, see our comparison of rotating versus standard infant seats.
Convertible car seats
Rear-facing. Easy at the Level 2 recline angle, but again the front passenger could use more space.
Forward-facing. A B. Cars.com found installation easy and the convertible fit well.
Some vehicles need the head restraint removed or raised to seat a car seat flush against the seatback, and some have fixed restraints that cannot be moved at all. Check your vehicle manual before forcing anything, and note that where a fixed restraint holds the seat off the seatback, that is a fit problem rather than something you can work around. See our convertible seats.
Boosters
The buckles are on short stalks that sit flush with the seat bottom cushion, so kids will likely have a problem buckling up independently.
Will your stroller fit?
Cars.com's Car Seat Check does not measure cargo volume, so the stroller guidance below is ours rather than theirs.
Cubic feet is the wrong number to shop on anyway. What decides whether a stroller fits is its folded footprint against the width between your wheel wells and the height to your cargo cover. A trunk can have generous volume and still refuse a wide fold.
Measure the space you will actually load into, whatever shape it is: how deep it is, its narrowest width (usually between the wheel arches, or between the bed rails on a pickup), and the height of the opening you have to lift over. Then compare against the folded dimensions of whatever you are considering. If the numbers are close, a compact fold like the Cybex Beezy leaves room for everything else; if you have space to spare, a full-size frame like the UPPAbaby Vista V3 earns it back in storage and expandability. Browse all strollers.
Lexus NX 350h takeaway
A useful reminder that a premium badge does not buy you car seat space. This is a compact SUV and it behaves like one. Cars.com's front passenger for this check was 5-foot-8; if yours is that height or taller and you are rear-facing, cross-shop something longer rather than something more expensive.

How a car seat fits and installs depends on your exact vehicle (its model year, trim, and seating configuration) and your exact car seat model. The instructions that came with your car seat and your vehicle owner’s manual always control. If anything in this article ever conflicts with those instructions, or with current guidance from the National Highway Traffic Safety Administration (NHTSA), follow the manufacturer instructions, your vehicle manual, and NHTSA, not this article.
Our fit findings are compiled from third-party sources, including independent car seat fit testing performed by Certified Child Passenger Safety Technicians and manufacturer specifications, that we believe to be reliable, and we provide all of it “as is.” Specifications, model years, and vehicle configurations change, and we do not guarantee the accuracy, completeness, or current status of any of it. This article does not replace a hands-on check by a Certified Child Passenger Safety Technician (CPST). If you are near Sumner, Washington, our in-store CPST check is free with every infant seat we sell, and we encourage you to use it or to find a certified technician near you.
