When your vehicle changes overnight: how fleets can manage OTA updates

Association of Fleet Professionals has raised concerns about over-the-air (OTA) updates reducing vehicle performance – but for fleets, the bigger issue is control.

The issue was discussed at a recent AFP Megafleets Committee meeting, where operators reported instances of vehicle capabilities changing after updates. No specific makes or models were named, but the concern was consistent: vehicles are being altered after they’ve been bought or leased, sometimes without warning.

In some cases, fleets say EV charging speeds have been reduced, turning a planned 30-minute stop into 45 minutes. Across multiple vehicles, that can quickly affect route planning, downtime and service delivery.

As AFP chair Paul Hollick put it:
“Manufacturers are no doubt making these changes for good reasons such as improved battery life or even safety, but they are also reducing the capabilities of a vehicle long after the fleet has decided to buy or lease it, and that simply doesn’t seem right. It may even potentially be a breach of contract.”

For fleet managers, this creates three practical challenges:

  • Planning risk – routes and downtime assumptions can shift
  • Compliance risk – system changes may affect safety features
  • Control gaps – limited visibility of what’s changed and why

In response, fleets may need to treat software updates as part of routine management. That means keeping records of software versions, encouraging drivers to report changes, and building flexibility into schedules where possible.

Fleet platforms can also help. Tools from providers such as Chevin and Lightfoot give visibility over vehicle use and performance, helping fleets spot changes more quickly.

Vehicles are no longer static assets. As software becomes a bigger part of how they operate, managing updates is becoming part of the job.
