AWS IoT FleetWise will no longer be open to new customers as of April 30, 2026. Existing AWS IoT FleetWise customers can continue using the service. The [Guidance for Connected Mobility on AWS](https://aws.amazon.com/solutions/guidance/connected-mobility-on-aws/) provides guidance on how to develop and deploy modular services for connected mobility solutions that can be used to achieve equivalent capabilities as AWS IoT FleetWise.

# Update multiple AWS IoT FleetWise vehicles
<a name="update-vehicles-cli"></a>

You can use the [BatchUpdateVehicle](https://docs.aws.amazon.com/iot-fleetwise/latest/APIReference/API_BatchUpdateVehicle.html) API operation to update multiple existing vehicles at one time. The following example uses the AWS CLI.

To update multiple vehicles, run the following command.

Replace *file-name* with the name of the .json file that contains the configurations of multiple vehicles.

```
aws iotfleetwise batch-update-vehicle --cli-input-json file://file-name.json
```

**Example – vehicle configurations**  

```
{
   "vehicles": [ 
      { 
         "vehicleName": "vehicle-name",
         "modelManifestArn": "model-manifest-arn",         
         "decoderManifestArn": "decoder-manifest-arn",         
         "mergeAttributes": true,         
         "attributes": {                    
         "key": "value"
         }     
      }, 
      { 
         "vehicleName": "vehicle-name",         
         "modelManifestArn": "model-manifest-arn",         
         "decoderManifestArn": "decoder-manifest-arn",         
         "mergeAttributes": true,         
         "attributes": {                     
         "key": "value"
         }     
      }
   ]
}
```

You can update up to 10 vehicles for each batch operation. For more information about the configuration of each vehicle, see [Update an AWS IoT FleetWise vehicle](update-vehicle-cli.md).

If you [enabled encryption](key-management.md) using a customer managed AWS KMS key, include the following policy statement so that your role can invoke the `BatchUpdateVehicle` API operation.
