The GMC Hummer EV is not just a vehicle; it’s a show of force, a high-voltage tank dressed in LED armor and rolling on 35-inch tires.
With 1,000 horsepower, torque-vectoring wizardry, and CrabWalk steering that seems more like a Marvel stunt than a real-world feature, the Hummer EV is GM’s biggest swing yet in the electric space, and by and large, it’s connecting.
But as any experienced test driver or grizzled engineer will tell you, it’s often not the big things that come undone. Sometimes, it's a misaligned piece of roof hardware that turns a revolutionary machine into a warranty folder growing thicker by the month.
One person went to the GMC Hummer EV Facebook Group to see if anyone else had the same issues he was having.
“Hi, everyone! I’ve been a proud (and originally excited) owner of a 2025 Hummer EV, and I wanted to share my experience with fellow owners, and prospective owners, and would love feedback from other owners who have had issues...
Since purchasing the vehicle, I’ve experienced a long series of repairs that have seriously shaken my confidence in the reliability and safety. I’ve had roof leaks, a full axle failure that left me stranded for 8 hours and caused loss of power at an intersection with no brakes, steering, or acceleration, rattling from the rear suspension, a malfunctioning tailgate GM admitted they can’t fix, multiple EV loaners that also failed, and most recently...a charging system noise that now sounds like a fan with broken chain ticking.
Some of the issues were so severe I’ve had to buy a separate gas-powered vehicle just to travel long distances safely...
After multiple visits to the dealership, probably 3 to 4 times a month, I’ve now collected a comprehensive and long list of repair orders and have entered a lawsuit with General Motors. I cannot comment specifically on this lawsuit, but just know that for every day that goes by, I add another defect to my case, and it's growing. Just these past weeks, technicians confirmed that some parts, like the I-Bars near the roof (including the rear one you can't take out yourself...), were installed incorrectly at the factory, causing water leaks and interior damage.
I understand EVs are new and evolving, and I really wanted this truck to work out. But it’s been an incredibly stressful journey. I’ve loved the design, features, and performance, but I can’t ignore what this has cost me in time and peace of mind. This is not an EVs are better/worse than gas cars post. This is simply my experience with this and other GM EVs (remember how I mentioned all their EV loaners failed in some way). I know people with other brand EVs that have had nothing but good experiences. *I am making it very clear I have no preference over gas or electric, and this is not political*
I just wanted to share my experience! Thank you, everyone.”
That’s not your typical griping on social media. That’s a consumer under pressure, trying to stay rational while documenting a saga of dealership visits and defects that would make most owners scream. But here’s the key: it’s one voice.
2025 GMC Hummer EV Specs: Power, Size, Range & Pricing
- Available in dual-motor “2X” and tri-motor “3X” configurations, delivering up to 1,000 horsepower and 11,500 lb-ft of torque. The 2X model produces 570 hp, while the 3X hits the full 1,000 hp mark
- Measures approximately 216.8 in (length) × 86.7 in (width) × 79.1 in (height), with a 135.6-in wheelbase, weighing in around 9,640 lb (4.5 tons), making it one of the heaviest consumer EVs on the road
- Offers an EPA-estimated range between ~311 miles (2X) and up to 367 miles (3X trim, GM estimated), with support for 800V, 350 kW DC fast charging
- Base MSRP starts around $99,000 for the 2X, rising to $107,000+ for the 3X trim. Production began in November 2021, with ~14,039 units built across pickup and SUV as of October 2024; US annual sales climbed from 854 in 2022 to about 13,993 units in 2024
A strong one, yes, but not representative of the Hummer EV tribe at large. Doug Parr, another owner, brings some balance to the discussion.
“I’ve had a few annoying issues, but nothing like yours… I have owned close to 30 different vehicles, and this is by far my favorite.”
He mentions some common teething problems, charge port doors, and windshield wiper shenanigans, but nothing that derailed his enthusiasm. Doug’s perspective echoes across much of the owner community: the Hummer EV has quirks, but for most, it’s still the most exciting machine they’ve ever owned.
General Motors isn’t asleep at the wheel. The Ultium platform underpinning the Hummer EV is already anchoring other models like the Cadillac Lyriq and Chevrolet Blazer EV. It’s modular, scalable, and designed for mass production. And even while navigating parts shortages and post-pandemic growing pains, GM has pushed ahead with real volume. The Hummer EV is no vaporware dream; it’s on the road, and in growing numbers. Most of them are functioning exactly as intended, proving the platform’s strength. But the margin for error in a vehicle this ambitious is razor-thin.
Hummer EV Owner Faces Service Delays & Steering Issues
Take Junior Smith, another commenter, who’s also experiencing long-term service delays and issues with power steering and high-voltage components. “What’s worse,” he adds, “is now another Hummer we bought under our company is starting to have issues.” It’s frustrating. But again, Junior’s tone, like Lewless-Clark’s, isn’t angry for the sake of being angry. He’s giving the system time. Hoping for a buyback. Trying to do it the right way. These aren’t social media warriors looking for clout. They’re early adopters trying to help fix a machine they still admire.
Why Drivers Adore the GMC Hummer EV Despite Quality Quirks
And admiration is the undercurrent here. For every horror story, there are a dozen posts praising the Hummer’s off-road chops, its space-age UI, or the joy of rolling silently through snow in a truck that looks like it was designed in a bunker by Tony Stark. The technology is radical. And yes, sometimes radical breaks. Especially when built at scale, on a timeline, with human hands. That doesn’t excuse poor quality control, but it does explain how something like misaligned I-Bars makes it out the door and into a six-figure truck. It's not ideal. But it's also not the full story.
GMC Brand History: From 1911 Trucks to 2025 Hummer EV
- Founded in 1911 from early truck companies, GMC became a major wartime supplier, producing over 600,000 trucks during World War II and achieving coast‑to‑coast expeditions that spurred early automotive innovation
- Over the decades, GMC differentiated itself from Chevrolet by emphasizing higher-end trims (like Denali) and commercial-grade durability, allowing it to command premium pricing for essentially mechanically similar models
- Riding the wave of SUVs and crossovers, GMC saw explosive growth in the 1980s and 2000s with vehicles like Jimmy, Yukon, Acadia, and Terrain. In recent years, it entered new markets like South Korea (2022) and China (2025).
- With the launch of the Hummer EV sub‑brand in 2021, GMC pivoted into EVs. U.S. sales reached ~583,300 in 2021 (best since 2017), followed by another record performance in 2023 with retail sales up ~6.5% year-over-year
One seasoned voice, Mark Smiley, reminded the group: “Just make sure and ask the dealership if they would like to buy the vehicle back as a result of all of these issues… I was fully reimbursed both times.” Smiley’s calm, lemon-law-savvy advice underlines a vital truth: even when things go wrong, the path to resolution doesn’t have to be scorched earth. GM has channels. They may not be perfect, but they exist, and many owners have successfully navigated them.
Lewless-Clark’s story matters. But it also proves something else: the Hummer EV is a platform worth fighting for. It’s not just a truck, it’s GM staking a claim on the electric frontier. And like any pioneer expedition, there will be missteps. But make no mistake, the overall trajectory here is forward. Lewless-Clark’s unfortunate experience shouldn’t overshadow the thousands of trouble-free miles owners like Doug, Mark, and many others are logging every month.
That’s the gamble of innovation. Sometimes it doesn’t pay off for everyone at the same time. But the Hummer EV? It’s real. It’s spectacular. And for most who own one, it's still worth every kilowatt.
What would you do in this situation? Would you look to trade in your Hummer EV?
