Can you try redeploying the car app again. For that first do following

1. Delete the .car application from /repository/deployment/server/carbonapps
2. Delete any existing streams defs (related to APIM stats) by login to DAS management console and going to Manage > Event > Streams
3. Re deploy car app by putting it in /repository/deployment/server/carbonapps

If everything goes well you would see two scripts in Manage > Batch Analytics > Scripts section. Try to execute each script and see if there is any error.
