AI in the Showroom: What BMW’s ChatGPT Configurator Tells Us About Data Protection Risk
A Data Protection Officer’s perspective on AI, automotive retail and accountable risk management
BMW’s decision to make its vehicle configurator available through ChatGPT shows how quickly generative AI is moving from experimentation into customer-facing services.
A customer can describe the vehicle they need in ordinary language. The AI-assisted tool can then interpret those requirements and direct the customer towards suitable models, specifications or available stock.
That may improve the customer journey. It may also create material data protection risk if the system is deployed without proper governance.
The question is not whether AI should be used. It is whether the organisation can show that it understands the processing, has assessed the risks to individuals and has put proportionate controls in place.
Conversational AI Is Entering the Vehicle Market
BMW is not operating in isolation. Mercedes-Benz has trialled ChatGPT functionality within its MBUX voice assistant using Azure OpenAI Service. The stated aim was to support more natural dialogue, follow-up questions and broader information retrieval.
Volkswagen has also integrated ChatGPT into its IDA voice assistant through Cerence Chat Pro. Volkswagen has stated that ChatGPT does not gain access to vehicle information and that relevant queries are handled through an automotive-grade integration layer.
The use cases are not identical. BMW’s example centres on retail configuration and product recommendation. Mercedes-Benz and Volkswagen have focused more on in-car assistance, voice-enabled controls and information retrieval.
However, the underlying data protection issues are closely aligned. They include natural language input, personalisation, inferred preferences, third-party AI infrastructure, transparency, security, accuracy and accountability.
Why Does This Matter Under UK Data Protection Law?
The UK GDPR and the Data Protection Act 2018 do not prohibit the use of AI. They do require personal data to be processed lawfully, fairly and transparently. Organisations must also follow the principles of collecting only necessary data, keeping information accurate, protecting it securely and being able to demonstrate compliance.
The ICO’s guidance on AI and data protection applies established data protection principles to AI systems. It places strong emphasis on governance, fairness, transparency and Data Protection Impact Assessments.
A Data Protection Impact Assessment, or DPIA, is a structured process for identifying and reducing risks to people’s rights before high-risk processing begins.
The ICO’s AI and data protection risk toolkit also gives organisations a practical structure for identifying and reducing risks created by their own AI systems.
The European Data Protection Board’s opinion on AI models is relevant too. It considers legitimate interests, anonymisation and the use of personal data during the development and deployment of AI models.
For an AI car configurator, the critical issue is not simply the presence of a chatbot. It is the processing context.
- What information is collected?
- How are customer prompts interpreted?
- Is the information combined with account, location, finance, dealership or stock data?
- Could the output influence a customer’s purchasing decision?
- Has the customer received a meaningful explanation of what is happening?
What Are the Core Data Protection Risks?
1. Lawfulness, Fairness and Reasonable Expectations
A customer may think they are only asking for a practical recommendation.
“I need an SUV with room for three children, low running costs and enough boot space for a wheelchair.”
That prompt may reveal family composition, mobility needs, financial priorities and lifestyle information. Some of that information may be sensitive in context, even if the organisation did not ask for it directly.
Fairness requires more than identifying a lawful basis. Organisations should assess whether the processing is within the customer’s reasonable expectations. They should also consider whether the system could influence customers in unexpected ways or have a disproportionate effect on vulnerable people.
2. Transparency and Explainability
Conversational tools can feel informal, but they may sit on top of complex processing chains.
Customers should receive clear information about:
- Whether they are interacting with an AI system
- What personal data is being used
- Whether their prompts are retained
- Whether the information is used to improve the service
- Which third parties are involved
- How recommendations are produced at a meaningful level
The ICO’s work on transparency and explaining AI-assisted decisions is especially relevant where an output may affect a person’s choices.
3. Accuracy and Inappropriate Reliance
Generative AI can produce confident but inaccurate outputs. This is often called an AI hallucination.
In a car configurator, the system could misstate a model’s availability, running costs, environmental performance, finance options, safety features or suitability for a particular use.
The accuracy principle still applies. Grounding the system in a controlled and verified product knowledge base can reduce the risk. If it relies on broader or uncontrolled content, the risk changes.
Organisations should not present generative outputs as authoritative unless they have been appropriately limited, tested and monitored.
4. Collecting Only Necessary Data
Natural language systems can encourage people to disclose more information than is needed.
A well-designed configurator should not invite customers to provide unnecessary personal data. Clear prompt design, input filters, warnings shown at the right time and carefully chosen examples can help reduce that risk.
Organisations must also be able to justify how long conversational logs are kept. They should understand whether those logs are linked to customer accounts, used for analytics, used to improve the service or used during model development.
5. Supplier and Data-Flow Accountability
Automotive AI systems may involve a vehicle manufacturer, dealership network, cloud provider, AI model provider, voice technology provider, analytics supplier and finance or insurance partners.
A controller decides why and how personal data is used. A processor handles personal data on the controller’s behalf. These roles should be clearly analysed, documented and reflected in contracts and governance records.
The organisation deploying the service must understand:
- Where personal data flows
- Which additional suppliers are involved
- Whether international transfers take place
- What security measures apply
- Whether customer data may be used to train or improve AI models
A supplier’s reputation or a high-level assurance statement is not enough.
6. Profiling, Automated Decisions and Consumer Vulnerability
Profiling means using personal data to evaluate or predict aspects of a person, such as their preferences, behaviour or financial position.
A configurator may not make a decision with a legal or similarly significant effect on its own. The risk increases if it profiles customers, ranks products by inferred affordability, directs people towards finance options or personalises offers in a way that materially influences their choices.
Organisations should assess what the system actually does rather than relying on the marketing label attached to it. If the system evaluates personal aspects of an individual and produces recommendations that significantly affect them, further safeguards and an assessment of automated decision-making rules may be required.
What Does Good AI Governance Look Like?
A conversational AI configurator should be treated as an AI-enabled processing activity that requires structured governance.
Before launch, I would expect to see controls such as:
- A Data Protection Impact Assessment: Cover the AI lifecycle, user prompts, model outputs, third-party processing, international transfers, retention, people’s rights and risks to vulnerable customers.
- A documented lawful basis: Complete a legitimate interests assessment where the organisation relies on legitimate interests. This assessment checks whether the processing is necessary and balanced against people’s rights.
- Clear customer information: Explain the AI interaction, how information is used, how long it is kept and how a person can ask for help.
- Prompt and output controls: Reduce unnecessary collection of personal data and limit inaccurate or unsupported answers.
- Human oversight: Provide escalation where recommendations relate to finance, safety, accessibility needs or other higher-risk matters.
- Verified knowledge sources: Base recommendations on controlled manufacturer data rather than uncontrolled online content.
- Testing and monitoring: Check accuracy, bias, security, inappropriate personalisation and model drift, which means the system’s performance changing over time.
- Supplier checks: Review contracts, security assurances, additional suppliers, audit rights and international data transfers.
- Retention and deletion controls: Set clear rules for prompts, logs, analytics information and any data used to improve the system.
- Incident response plans: Prepare for data leakage, misuse, inaccurate recommendations and security incidents.
These are not tick-box activities. They provide the evidence needed to demonstrate accountability.
Innovation Is Not the Risk. Unmanaged Deployment Is.
There is nothing inherently unlawful about using generative AI to support vehicle configuration, product discovery or in-car assistance.
Used well, conversational AI can improve accessibility, reduce friction and help customers navigate complex choices.
The answer is not to resist innovation. It is to support innovation with governance that is practical, evidenced and capable of being tested.
Organisations should maintain a live risk assessment, test the system with realistic prompts, scrutinise supplier claims, monitor outputs and give customers clear information and meaningful control.
BMW’s ChatGPT configurator is more than a digital sales channel. It is a reminder that AI risk management sits at the intersection of data protection, consumer trust, product governance and operational resilience.
For Data Protection Officers, or DPOs, the objective is not to block AI. It is to make sure AI is explainable, fair, proportionate and accountable.

Does UK Data Protection Law Prevent Organisations From Using AI?
No. Organisations can use AI, but any use of personal data must be lawful, fair, transparent, accurate, secure and accountable.
What Should an Organisation Do Before Launching Customer-Facing AI?
It should understand what data the system uses, document its lawful basis, assess the risks, give people clear information, review suppliers, test outputs and provide appropriate human oversight. A Data Protection Impact Assessment may be required where the processing is likely to create a high risk to people.
How Data Protection Made Easy Can Help
Data Protection People supports organisations that want to use data, technology and AI responsibly while meeting their duties under UK GDPR and related law.
Through Data Protection Made Easy, organisations can access practical data protection advice, support for ad-hoc queries, policy and governance work, training, supplier assurance and risk-based reviews.
Where work crosses into wider security assurance, organisations may also need support with information security management, ISO 27001 readiness, PCI DSS considerations or Cyber Essentials certification. Not every framework will be relevant to every AI project.
The principle remains the same. Effective AI governance depends on understanding the data, the technology, the suppliers and the risks, then putting controls in place that can be demonstrated.
