General Motors has released a Service Update for select units of the 2022-2023 BrightDrop electric vans for a series of software updates. Service Update number N252502390 applies to certain units of the 2022-2023 BrightDrop that may require software updates that improve the customer experience and optimize future over-the-air (OTA) updates. This should take certified GM technicians approximately one hour to perform.
Examples in dealer possession can’t be sold or released until the software update is performed. At this time, it’s unclear how many electric vans are affected by the service update.
This service update only applies to the 2022 and 2023 model years of the BrightDrop. That means it applies to the BrightDrop EV600 and BrightDrop Zevo 600, which are essentially the same, but with different names. Some parts of the NHTSA documentation refer to the van as a Chevrolet, but it wasn’t sold under the Chevy banner until the 2025 model year.
GM issued a similar service update in March of 2024 for the 2023 BrightDrop Zevo 600. It pertained to a software defect in the battery energy control model in certain units. The solution was to reprogram the battery energy control module.
The updates specified in the documentation for this new service update include reprogramming the battery energy control module and reprogramming the radio. In much the same way modern computers and smart devices get frequent software updates for general enhancements and bug fixes, that’s likely what this service update is about.
The BrightDrop EV600 and Zevo 600 are propelled by Ultium Drive motors, which are supplied with electricity by Ultium batteries. The van in these model years is a FWD EV able to develop 240 horsepower and 300 pound-feet of torque, or 300 horsepower and 390 pound-feet of torque with optional AWD.
With regard to the BrightDrop van’s charging characteristics, it supports 200 kW max DC fast charging in addition to AC Level 2 11.5 kW or optional 19.2 kW charging capabilities. Peak recharging rate is 160 miles of range per hour of charging.
Now available as a Chevrolet, the Chevy BrightDrop is available as the short 400 model or the long 600 model, and its max range rating is 272 miles.
Comments
“Needs another software update” is GMs slogan these days.
How about, “We’re never finished building your car!”
Perhaps you should have one story that states early model Ultium vehicles require a comprehensive software update, rather than a model-by-model approach. Given that the Brightdrop, Hummer, and Lyriq share a lot of Ultium components, it makes sense that they would all need a similar update.
As many Bright drops that are stored unsold they may have another environmental use. Submerged where coastal erosion is a problem.
This should account for a couple dozen recalls!
They’re very easy to find as they parked like cord wood in Flint and Pontiac!
2002tii,
Maybe Oprah could give them away; “You get a car, you get a car, you get a car, you get a car, you get a car, EVERYBODY gets a car”.
My stove bolt 52 pickup doesn’t need a soft ware update. Nor does it need a new engine because some engineer thought 0-20W oil was sufficient.
How often does your I-phone need a software update?
