Automated assessment, not a hands-on review. Reliability proxies do not predict breakdowns; running economics excludes purchase price and depreciation.

What these numbers mean for this model

This assessment uses the 2024 GMC Hummer EV SUV 2M20 (Automatic (A1)) specification row: 303 miles rated range, 1.67 mi/kWh, and 212 kWh usable battery. It does not average every trim or model year. Its efficiency score is 46/100 within SUV peers. Changing the available peer set can change its relative score.

Fuel comparison: GMC Yukon, 18 MPG, in the same SUV body class. Modeled annual fuel savings are $948; negative means the gas rival is cheaper to fuel. This is not an exact trim or purchase-price match. Local rates and charging habits can change the result; use the ownership calculator before making a purchase decision.

Evidence gaps

  • Recall records span available model-family records, not verified fleet exposure or complete year coverage. Check your VIN separately; zero stored recalls does not mean none exist.
  • No model-specific issue checklist is available; this metric receives a neutral score.
  • Battery estimate: 2.0% per year, based on an assumed default, scored neutrally. The underlying curve is not independently verified here.
  • Charging speed is modeled from peak power; weather, battery temperature, and the charging curve can produce a different result.
  • This assessment remains usable but is excluded from search indexing until model-specific issue and battery evidence and an adequate same-class cohort are available.

What drives the score

Reliability proxies — 60/100

Recorded recall campaigns0 campaigns 60

0 campaigns across 1 model years with records. Coverage and fleet exposure are unverified, so this metric is neutral (60), not a breakdown-rate estimate. Zero records does not establish reliability.

Documented owner issuesNot yet curated 60

No curated issue list yet — scored neutrally rather than assumed clean.

Battery degradation2.0% / yr 60

Assumed 2.0%/yr — no model-specific curve; scored neutrally (60).

Efficiency — 46/100

EPA efficiency1.67 mi/kWh 21

Miles per kWh vs other SUVs. Drives every cost figure on this site.

EPA range303 mi 75

Rated combined range. Expect 20-30% less in freezing weather.

Fast-charge speed70 mi / 10 min 66

Modeled from peak 350 kW using a 72% taper assumption; not a measured charging test.

Economics — 35/100

Energy cost per mile13.9¢/mi 21

Scenario assumptions: 80% home at 17¢/kWh, 20% public DC at 48¢/kWh; not live rates.

Fuel savings vs gas rival$948/yr 45

Against the GMC Yukon (18 MPG) at $3.92/gal, 12,000 mi/yr.

Modeled capacity-loss allowance$560/yr 60

Illustrative lost capacity × $132/kWh. Not a repair bill, replacement quote, resale loss, or probability of failure.

Road-trip charging cost$28.71 / 100 mi 21

Cost of 100 miles bought entirely at public DC fast chargers.
