How Do Car Seats Fit in a 2018 Infiniti QX80?

Infiniti's full-size SUV combines luxury and utility on a large scale, and for 2018 the QX80 gets an update with fresh styling, an upgraded cabin and some new convenience features, like a rearview camera mirror. As with last year's model, certain car seats did better than others and tricky-to-access Latch anchors complicated installation.

Last time we tested a QX80, it was with captain's chairs in the second row. This time, our model had a bench seat, and there was just enough room to accommodate three car seats across using our parameters: We install the infant seat in the second row's middle spot with the booster and convertible in the outboard seats. A child sitting in the booster seat must be able to reach the seat belt buckle, and all three seats need to be at proper angles for safety — no wedging them in.

So-So

  • Latch, Grade C: There are two sets of Latch anchors in the second row; they sit in slits in the leather and are positioned up high, so accessing the anchor with both the chunky connectors and skinny ones requires twisting and some muscle. There are three tether anchors all the way down the seatback; the outboard ones are marked but the middle one is hidden under a flap. In the third row, there are no lower anchors and only one top tether anchor.
  • Infant seat, Grade B: There was ample room for this seat, but connecting the seat's skinny, hooklike connectors to the anchors took some work.
  • Rear-facing convertible, Grade B: There was ample room for this seat, but we also needed some muscle to install it with its chunky connectors.
  • Forward-facing convertible, Grade B: After removing the head restraint, this seat fit well, but installation was again complicated by the Latch anchors' placement.
  • Booster, Grade B: After removing the head restraint, the booster fit well. The buckle stalks sink into the cushions, however, making them tough for kids to use.
  • Third-row access, Grade C: The second-row seats tumble forward with ease, but the tall step-in height will be tough for smaller kids to manage independently. Also, the second-row seats don't slide, limiting their flexibility.
  • Third-row booster, Grade B: After removing the head restraint, the booster fit well. The buckle stalks are on floppy bases, however, making them tough for kids to use.
  • Third-row forward-facing convertible, Grade B: We again removed the head restraint to get a good fit. Since there are no lower Latch anchors in the third row, we used the seat belt to install the convertible, which was easy. There's only one top tether anchor for the third row, and it's positioned awkwardly in the lip of the cargo area. When it's in use, it cuts into cargo space. Connection is awkward because you have to remove the cargo net and mat to access it.

Grading Scale

Solid indicates an A grade for optimum ease of use and fit. So-So indicates B or C grades for one to two ease-of-use or fit issues. Skip It indicates D or F grades.

A: Plenty of room for the car seat and the child; doesn't impact driver or front-passenger legroom. Easy to find and connect to Latch and tether anchors. No fit issues involving head restraint or seat contouring. Easy access to the third row.

B: One room, fit or connection issue. Some problems accessing third row when available.

C: Marginal room plus one fit or connection issue. Difficult to access third row when available.

D: Insufficient room, plus multiple fit or connection issues.

F: Does not fit or is unsafe.

About Cars.com's Car Seat Checks

Editors Jennifer Geiger, Jennifer Newman and Matt Schmitz are certified child safety seat installation technicians.

For the Car Seat Check, we use a Graco SnugRide Classic Connect 30 infant-safety seat, a Britax Marathon convertible seat and Graco TurboBooster seat. The front seats are adjusted for a 6-foot driver and a shorter passenger. The three child seats are installed in the second row. The booster seat sits behind the driver's seat, and the infant and convertible seats are installed behind the front passenger seat.

We also install the forward-facing convertible in the second row's middle seat with the booster and infant seat in the outboard seats to see if three car seats will fit; a child sitting in the booster seat must be able to reach the seat belt buckle. If there's a third row, we install the booster seat and a forward-facing convertible. Learn more about how we conduct our Car Seat Checks.

Parents should also remember that they can use the Latch system or a seat belt to install a car seat, and that Latch anchors have a weight limit of 65 pounds, including the weight of the child and the weight of the seat itself.
