2023 GMC Hummer EV
Limited data: few reports on file, read the verdict loosely
Too few owner complaints are on file to affirm this car. Treat it as unproven, not endorsed, and lean hard on a professional pre-purchase inspection.

Only 1 owner complaint on file for this exact model year, too few to judge long-term reliability. Treat this as unproven, not endorsed, and lean on a professional inspection.
Score breakdown, by factor
Full methodology →How it crashes
NHTSA’s own crash tests, separate from the reliability score above.
NHTSA hasn’t published a crash-test rating for this model year. That’s common for lower-volume or older models. It doesn’t mean the car is unsafe, just that this program hasn’t tested it.
Source: nhtsa.gov/ratings. Star ratings compare vehicles within the same class and size, not across every car on the road.

Questions to ask the seller
Questions worth asking any seller before you hand over money:
- Has this car been in any accident or had any structural, airbag, or flood-related repair? Do you have a clean title and a recent history report (Carfax / AutoCheck)?
- How many owners has it had, do you have the maintenance records, and why are you selling it?
- Are you open to me having an independent mechanic inspect it before we settle on a price?
