EV technology is wild.

Case in point, the 2024 GMC Hummer EV weighs more than 2.5 Corvettes, and yet it catapults from zero to 60 at nearly the same speed (3.3 vs 2.8 seconds). The designers of the Hummer seem well aware of this fact, given that you have to put the vehicle in Watts to Freedom mode for maximum acceleration.

The Hummer EV also comes with a hefty price tag, starting at $98,845 for the base trim and well over $150,000 for the highest addition. That makes it far more expensive than the Rivian R1T ($69,990) or Tesla Cybertruck ($81,895), although some would say it's worth it given the Hummer’s superior size, imposing looks or niche appeal.

If you’re on Team Hummer, you might be considering a certified pre-owned (CPO) model to save on buying new. But how does the parent company GMC handle CPO on Hummer EVs? Is there anything special to consider over GMC’s regular CPO program? How much extra are dealers charging for CPO Hummer EVs, and is it worth it?


Key insights

Like other CPO GMC vehicles, CPO Hummer EVs come with a one-year extension to both the factory bumper-to-bumper and powertrain warranties, as well as some other benefits like a pair of free tune-ups and roadside assistance.

Dealers charge around $12,500, or 12% extra, for CPO Hummers EVs compared with regular used ones. For one extra year of warranty protection and a small handful of benefits, that’s probably not worth it, especially given the limited selection of CPO Hummer EVs.

As an alternative to buying CPO, you can schedule an EV-specific pre-purchase inspection on a used Hummer EV (approximately $300) and purchase a separate two-year extended warranty from GMC (approximately $3,255).

How long is the CPO warranty on a Hummer EV?

All brand-new Hummer EVs come with the following factory warranty:

  • Three years/36,000 miles of bumper-to-bumper coverage
  • Five years/60,000 miles of powertrain coverage (including the EV drive unit)
  • Eight years/100,000 miles of EV coverage (including the battery and other miscellaneous “electric propulsion” components)

It’s also worth noting that, like most factory warranties, the coverage follows the vehicle, not the owner, so if you buy a used Hummer EV, you may inherit some coverage. For example, a one-year-old model with 10,000 miles will still have two years/26,000 miles of bumper-to-bumper coverage left on it.

Now, when you purchase a CPO Hummer EV, you’ll get one of two CPO warranties, depending on which GM-sponsored CPO program the dealer used to certify the vehicle:

  • For CarBravo Certified, you get six months/6,000 miles of additional bumper-to-bumper protection.
  • For GM Certified, you get one year/12,000 miles of additional bumper-to-bumper protection and a six-year/100,000-mile powertrain warranty (which essentially boosts your factory warranty by one additional year/40,000 miles).

Neither CPO warranty will extend your eight-year/100,000-mile battery warranty, but at least you’ll get some added protection for the electric motor (which is covered under the powertrain warranty).

How does Hummer EV’s CPO warranty compare?

Hummer’s CPO warranty is slightly below average compared with its closest competitors.

Rivian doesn’t officially have a CPO program yet, but the R1S – arguably the Hummer EV’s closest competitor on the market – comes with a four-year/50,000-mile bumper-to-bumper warranty from the factory (five-year/60,000 for quad-motor setups) and an eight-year/150,000-mile battery warranty. So you may get better superior warranty coverage from a used Rivian than from a CPO Hummer EV.

Tesla also doesn’t have an official CPO program yet, but all used Model X vehicles sold by Tesla itself come with a one-year/10,000-mile extension to the four-year/50,000-mile factory warranty.

Genesis and Porsche also offer longer warranties with their CPO EVs. The only competitor that can’t outpace a GMC Hummer is Ford since its EVs also come with a three-year/36,000-mile warranty from the factory and a one-year/12,000-mile CPO extension. Hummer actually has a small let up on Ford, since it includes one extra year of powertrain protection.

But overall, if you’re looking for an electric luxury SUV with maximum warranty protection out the gate, you might want to consider a quad-motor Rivian or a Tesla. Thankfully, you can still buy separate extended warranty protection for a Hummer EV, which we’ll discuss in a later section.

How much does a certified pre-owned Hummer EV cost?

The average asking price for a certified pre-owned Hummer EV is $123,799.

GM Certified Hummer EVs come with similar benefits to any other certified GMC vehicles, with only minor tweaks specific to EVs:

  • 24/7 roadside assistance, including lockout services, flat tire change (with your spare), battery jump-starts and towing to the nearest licensed GMC dealer or charging station.
  • Courtesy transportation including loaner vehicles or rental car assistance if none is available.
  • A three-day/150-mile exchange policy which allows you to exchange your Hummer EV for a different Chevrolet, Buick or GMC on the lot.
  • Two scheduled maintenance visits that would normally include oil changes, but for a Hummer EV, “it typically includes a multi-point inspection, fluid top off and diagnostics of the computer system” a GMC dealer told us.
  • Miscellaneous extras, including an OnStar trial, SiriusXM trial and vehicle history report.

Overall these are decent benefits for a CPO program. It’s also worth noting that Tesla has reported a general shortage of loaner vehicles nationwide, so Hummer EV owners are probably more likely to get a loaner vehicle than Cybertruck and Model X owners.

Is a CPO Hummer EV worth it?

For starters, let’s look at the average gap in price between CPO and pre-owned Hummer EVs.

According to Edmunds, an online auto marketplace, at the time of writing, there are 134 used Hummer EVs for sale nationwide with an average asking price of $110,951. Out of just four available CPO vehicles, the average asking price is $123,799.

That’s an extremely small sample size, but it does seem to suggest that dealers are asking roughly 12% more for CPO Hummers than used ones. For context, the industry average CPO upcharge is 6%.

On top of that, two of the CPO Hummers listed in Edmunds were CarBravo Certified, not GM Certified. That means the warranty is cut in half (12 to six months), and you get fewer benefits.

But even for the fully GM Certified Hummer EVs, paying 12% or roughly $12,500 extra probably isn’t worth it. There are companies now that can do a pre-purchase inspection on an EV for around $300, which includes a diagnostic test and a battery health check, and a roadside assistance plan from Allstate starts at just $89 per year.

Plus, GM itself will sell you an extended warranty on your Hummer EV that’s far more cost-effective than paying $12,500 for a single extra year (or less). So if you’re truly keen on buying a Hummer EV, let’s look at your extended warranty options and pricing before wrapping up.

    CPO vs. extended warranties for Hummers

    Two years into production, CPO Hummer EVs are both rare and expensive. That may change when three-year leases run out next year, but for now, you’ll find better deals and a better selection by looking at regular pre-owned models instead.

    GM will also sell you an extended warranty that costs far less than $12,500 for a single year of coverage. According to one dealer we spoke with, GM will add one year/12,000 miles to your Hummer’s factory coverage for $2,175 or two years/24,000 miles for $3,255.

    Extended warranties are also negotiable since dealers often bake hidden commissions into the price. To try negotiating a lower out-the-door cost for your warranty (and your Hummer EV in general), check out step eight of our guide to buying a used car.

    All things considered, buying a pre-owned Hummer EV with a separate inspection and extended warranty seems to be the more cost-effective option than buying it CPO.
