You cannot instantiate an abstract class, Jackson neither. You should give Jackson information on how to instantiate MyAbstractClass with a concrete type.

See this answer on stackoverflow: Jackson JSON library: how to instantiate a class that contains abstract fields

And maybe also see Jackson Polymorphic Deserialization

This exception :

InvalidDefinitionException: Cannot construct instance of com.vehicle.datatransferobject.VehicleDTO (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator)

means that Jackson didn't find a way to instantiate VehicleDTO that is the default constructor (no arg constructor) or a JsonCreator.
As you use a builder pattern you will configure the VehicleDTO class to make Jackson to instantiate VehicleDTO with the VehicleDTOBuilder such as :

@JsonDeserialize(builder = VehicleDTO.VehicleDTOBuilder.class)
public class VehicleDTO {
      ...         
}

And annotate your builder with JsonPOJOBuilder as :

@JsonPOJOBuilder(buildMethodName = "createVehicleDTO", withPrefix = "set")
public static class VehicleDTOBuilder{ 
   ...
}

According to the javadoc, JsonPOJOBuilder is :

used to configure details of a Builder class: instances of which are used as Builders for deserialized POJO values, instead of POJOs being instantiated using constructors or factory methods. Note that this annotation is NOT used to define what is the Builder class for a POJO: rather, this is determined by JsonDeserialize.builder() property of JsonDeserialize.

I was able to parse a JSON where Instant field is "2019-08-28T15:15:44.183Z"

First of all, ensure you have a dependency. E.g. in build.gradle

implementation 'com.fasterxml.jackson.datatype:jackson-datatype-jsr310'

Then configure ObjectMapper to use this dependency and not (de)serialize Instant as timestamps that it does by default. I setup my ObjectMapper as:

ObjectMapper mapper  = new ObjectMapper()
        .findAndRegisterModules()
        .disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
