Hummer EV SUV car seats

The 2024 GMC Hummer EV SUV represents a radical reinvention - transforming from gas-guzzling icon to silent electric powerhouse. But how does this 9,000-pound electric vehicle perform when tasked with protecting your most precious cargo? Our certified child safety technicians put it through rigorous testing to find out.

Bottom Line: The Hummer EV SUV accommodates three car seats simultaneously with mostly excellent results, though non-removable head restraints create some installation challenges for forward-facing configurations.

Latch System Evaluation: Grade A

A

Exceptional Accessibility

The Hummer EV SUV shines with its well-designed Latch system:

  • Lower Anchors: Two sets of clearly exposed anchors for easy connection
  • Tether Anchors: Three easily identifiable anchors on seatbacks
  • Installation Ease: No digging through seat cushions required

This is among the best Latch implementations we've seen in large SUVs, electric or otherwise.

Car Seat Compatibility Breakdown

A

Infant Seat (Chicco KeyFit 30)

  • Effortless installation using lower anchors
  • 5'6" front passenger maintained generous legroom
  • No interference from non-removable head restraints
  • Cavernous rear seat accommodates even large infant seats

A

Rear-Facing Convertible (Graco Contender 65)

  • Secure installation with no movement
  • Front passenger space remains uncompromised
  • Easy access to Latch anchors despite large seat size
  • Angle adjuster not needed for proper recline
B

Forward-Facing Convertible (Graco Contender 65)

  • Secure installation but with fit challenges
  • Non-removable head restraints prevent flush seatback contact
  • Note: Head restraints are removable in Hummer EV truck version
  • Safety not compromised but installation less than ideal
C

Booster Seat (Graco TurboBooster)

  • Head restraint again causes fitment issues
  • Seat cannot sit flush against vehicle seatback
  • Buckle stalks are long but elasticized - may challenge small hands
  • Older children may manage but not ideal for newly transitioned boostered kids

Three Car Seats: Yes, With Caveats

The Hummer EV SUV successfully accommodates three across in its second row:

Configuration Result
Infant + Convertible + Booster Fits but booster child must reach across for buckle
Forward-Facing in Center Works but head restraint issue persists
Access to Buckles Manageable but requires some flexibility

Pro Tip: Consider using seat belts instead of Latch for center installations to maximize outboard space when doing three-across configurations.

Important Safety Notes for Parents

Latch Weight Limits

Remember that Latch anchors have a 65-pound combined weight limit (child + seat). For heavier children:

  • Switch to seat belt installation when limit is reached
  • Always check your specific car seat's weight limits
  • Top tethers can still be used with seat belt installations

Head Restraint Solutions

For forward-facing seats affected by non-removable head restraints:

  • Contact GMC about potential aftermarket solutions
  • Ensure at least 80% of car seat contacts vehicle seat
  • Consult a CPST if unsure about proper installation

How the Hummer EV SUV Compares

Versus other large electric SUVs we've tested:

Feature Hummer EV SUV Rivian R1S Tesla Model X
Latch Ease A B+ A-
Three-Across Fit B A- C+
Booster Friendliness C B B-
Head Restraint Design Non-removable Removable Adjustable

Final Verdict

The 2024 GMC Hummer EV SUV delivers surprisingly good family functionality for such a massive vehicle. While the non-removable head restraints present some challenges for forward-facing configurations, the excellent Latch system and spacious interior make it a viable option for families transitioning to electric vehicles.

Best For: Families with mostly rear-facing children or those willing to work around the head restraint limitations. The Hummer EV SUV particularly shines for parents who frequently install and remove infant seats.

Consider Alternatives If: You primarily use booster seats or need maximum flexibility for forward-facing convertible installations.
