Video: GMC Hummer EV Breaks Down While Off-RoadingTFLoffroad - YouTube

Theoretically, electric vehicles are supposed to be more reliable than their gas-burning counterparts. There are fewer moving parts, which means fewer variables when it comes to things that could break. But EVs aren't totally immune to breaking down, as the TFLoffroad YouTube channel found out while on a trip through Moab with its GMC Hummer EV.

The channel was out driving the big Hummer down a rocky hill through Utah's incredible off-road park when the truck began to throw error messages. The first was a "one-pedal drive unavailable" message, followed by a "4WD unavailable, schedule service" message. Shortly after, the truck loses drive entirely, giving a "reduced acceleration, drive with care" message.


Interestingly, this isn't the first time TFLoffroad has dealt with this specific Hummer losing all drive. In a previous video, the car stops responding to the accelerator pedal in a similar manner, except back then, it was on the road at a busy intersection. The channel ended up having to pull the battery and plug it back in to get the Hummer moving again. Thankfully, all it took this time was a simple restart to get the accelerator to respond, though the error messages and the loss of 4WD persisted for the rest of the day.

It was only when the channel's host received an email the next day from the Hummer itself warning of a "critical issue with the electric drive unit" did everything reset back to normal. We hope it stays that way for the foreseeable future, for their case.

GMC did not respond to Road & Track's request for comment on this story.
