Video: I bought a $115,000 GMC Hummer EV and it IMMEDIATELY dumped me!


Not the kind of experience we expected with our all-new $115,000 GMC Hummer EV.

Without dithering around the issue, let’s cut to the chase: TFL’s all-new GMC Hummer EV broke down on a busy highway within a day of owning it. We just traded in our long-term Ford F-150 Lightning for this truck and we’re planning all the coverage we want to bring you over the next few months. The premise is simple: how successful or unsuccessful is GMC’s all-electric truck?

Then, during the filming of these videos, Roman got stuck on a busy highway when the Hummer EV refused to restart using the ignition button. Its electric shifter also didn’t move the truck out of park, even to allow for “limp mode.” The truck just didn’t move, leaving Roman to bring in the team (and a tow truck) to help.

It all started when the truck threw up another steering related fault and said it needed to go to the dealership for service. But the story ended up getting much more complicated from there.

GMC Hummer EV - stationary state parked

As you imagine it is not the kind of place to crash. Luckily, a police officer quickly arrived to help clear traffic away from the Hummer, while Roman coordinated the rescue operation. However, even though we brought a truck, we faced two major issues in moving the GMC out of harm’s way. It’s stuck in park, so you can’t hook up to recovery points to tow it flat (side note: GM insists you don’t tow that flatbed truck), because it won’t move. Even if it was in neutral, however, you’re still trying to pull a whopping 9,400 pounds – so you’ll need to bring a vehicle that can move that kind of weight.

What about calling OnStar?

“Of course, I called OnStar. They directed me to 14 different people, kept asking me for my phone number. They said I needed premium service, and finally they said the soonest they could get a tow truck here was in an hour,” Roman said of his experience doing the first thing most GM owners would likely do in the event of a breakdown. background on this, OnStar asked for his phone number in case he got disconnected, and the carrier also (strangely) asked for the truck’s VIN.

When the Hummer EV finally did some sort of power cycle, the instrument cluster displayed a message: “Start vehicle to view app.” Unfortunately, this means the truck has not under tension, even with Roman’s foot on the brake, and still refused to budge. The incident also prevented Roman from opening the trunk by normal means, either the button inside the truck or the key fob.

So what is the fix?

In the end, with Tommy’s help, Roman was able to hard reboot the Hummer EV, disconnecting the battery once they were able to open the front trunk. Pro tip: If you need to manually open the GMC Hummer EV’s frunk, there’s a small pull cable built in deep under the dash to do so. In our situation, the hard button under the grille to open the trunk did not work, nor did the interior electronic switch or the key fob.

After reconnecting the battery, there is a restart procedure to disengage the gear lever:

  • Press the brake for 20 seconds;
  • Open then close the driver window;
  • Open and then close the passenger window;
  • Open then close the left rear screen;
  • Open then close the right rear window;
  • Cycle passenger window (again);
  • Press the brake for 20 seconds

Yes, you have to go through all these prompts to unlock the shifter. Luckily, Tommy and Roman were able to get the vehicle back to the dealership after getting the Hummer EV out of this sticky situation.

What happens next?

As of this writing, technicians at our local GMC dealerships are working to diagnose and fix the problem. When we have an update on this we will let you know.

While this is a frustrating situation, we show an unfortunate real-world situation that we faced almost immediately after our GMC Hummer EV was delivered. Depending on where this might occur, it could lead to dangerous circumstances for a Hummer EV driver or surrounding motorists.

To recap this truck’s life so far, here’s where we are. GM’s Factory Zero (Hamtramck) plant built the truck in March 2022. From there, several months passed before the truck finally arrived this month. We don’t know for sure where the truck was or how it was stored/shipped for the intervening months, but the GMC Hummer EV arrived here in Boulder, Colorado with delivery mileage.

Obviously, if you were to spend $115,000 on a brand new electric truck and faced these issues, you would rightly be upset and demand answers. This is what we’re working on, so stay tuned for more updates as the story develops.
