GMC Hummer EV review

Verdict: the most spectacular vehicle here and the least rational purchase. Buy used at the $75,000 discount, never new — and only if you have a second car and a patient electrician.

Nothing prepares you for the GMC Hummer EV in person. It is nine thousand pounds of electric theater: CrabWalk four-wheel steering, removable roof panels, air suspension, and up to a reported 1,160 horsepower in the Carbon Fiber Edition, good for a 2.8-second 0–60 time in something the size of a studio apartment. The 2026 range runs $99,095 (2X) to $107,195+ (3X), with 316–363 miles of pickup range and up to 10,600 lb of towing. It is, by every objective measure, an absurd and magnificent object. It is also, by every reliability measure available, a first-generation product with a service network that is not ready for it.

The complaint catalog is the longest in this cluster, so let's organize it. Powertrain and battery: "Service Lithium-Ion Battery" warnings at low mileage, charging-system failures, water intrusion into the battery pack, and three active NHTSA recall areas on the 2024s — battery fire risk (remedy still under development), sudden drive-power loss from rear drive-unit wiring, and seat-belt fastener torque. Body and hardware: the power swing tailgate fails so regularly it tops every forum complaint list; charging-door mechanisms feel flimsy and fail to latch; roof leaks are common enough for a TSB — one 2025 owner's factory-misinstalled roof I-bars caused leaks and interior damage on the way to a lawsuit. Electronics: SuperCruise "Service Driver Assist" failures are so common owners call it a "well known problem"; infotainment freezes; OTA updates effectively stopped in late 2023, so don't expect Tesla-grade continuous improvement. Suspension: air-spring leaks, particularly on trucks that actually go off-road — the hardware isn't as durable as the marketing.

Then there's the force multiplier: the dealers. Most GMC dealers have near-zero Hummer EV experience — this isn't an exaggeration, it's the consistent owner report. Horror stories abound of trucks sitting in service bays for weeks while technicians wait for guidance from GM, and specialized Ultium parts take weeks to months. Documented service stays run 30 to 131 days. One Edmunds reviewer with an Edition 1 SUV waited three weeks just for an appointment, then watched the truck sit at the dealer for over a month with a transmission-fluid leak. A 2025 owner in the TorqueNews saga had roof leaks, a full axle failure that stranded them eight hours with no brakes, steering, or acceleration, a tailgate GM admitted it can't fix — and bought a separate gas car for long trips while suing GM. That is one voice, but it's a detailed one, and the pattern around it is consistent.

The hidden cost is the one nobody budgets for: insurance and electricity. A Facebook owner vented that higher insurance premiums and charging costs wiped out the expected fuel savings — the total-cost-of-ownership shock unique to a 9,000-lb EV. This thing can overwhelm a basic home charging install; owners discuss upgraded electrical service the way normal EV owners discuss wall connectors. Towing collapses the range. Seventy-five-mph cruising collapses the range. Physics does not care about the badge.

So why does anyone buy it? Because nothing else does what it does, and the used market has now priced the pain. Used 2024s average around $75,800 nationally — $20,000 to $40,000 under original MSRP, with low-mileage examples in the mid-$60,000s. That is a staggering discount on a two-year-old $100,000+ vehicle, and it reframes the proposition: at $75,000, the Hummer EV is an exotic toy at a used-Cayenne price. The battery and motors themselves show minimal degradation at 20,000–30,000 miles per independent analysis — the expensive core is sound; it's everything bolted around it that fails. The 8-year/100,000-mile battery warranty covers the component you'd actually fear.

Who should skip it: anyone who needs one vehicle to be dependable — this cannot be your only car. Anyone without a second vehicle and a high tolerance for service sagas. Anyone expecting fuel savings; the insurance alone may erase them. Anyone buying new at $99,000+ when the used market offers the same truck at a $30,000 discount. Anyone far from a GMC dealer with actual EV technicians — verify the service department's Hummer EV experience before you buy, not after. And anyone who tows heavy regularly; the range collapse is real and the charging stops are long.

Sweet spot: a used 2024 2X at around $73,000–$76,000 — maximum depreciation already taken by someone else, battery warranty intact, all recalls addressable. Years to avoid: 2022, the Edition 1 first-year chaos (water intrusion, software, build quality); treat 2023 with the same suspicion unless fully documented.

The Hummer EV is the best argument in this group for buying used: let the first owner take the depreciation, the recalls, and the 131-day service stays, and you get the spectacle at a working person's price. Just keep the second car. You'll need it.
