Understanding Your Legal Obligations When a Complaint Arrives
When a customer complains about a vehicle purchased from your dealership, the Consumer Rights Act 2015 imposes specific obligations on how you must respond. You are legally required to acknowledge the complaint promptly, investigate the claim thoroughly, and provide a substantive response within a reasonable timeframe, typically 14 days. Failure to respond appropriately can escalate a manageable complaint into a formal dispute, court action, or reputational damage through online reviews and trading standards involvement.
The CRA 2015 grants customers statutory rights that override any exclusion clauses in your terms and conditions. Vehicles must be of satisfactory quality, fit for purpose, and as described at the point of sale. When a customer alleges a breach of these rights, your response must address the specific statutory grounds they are invoking, not simply offer goodwill gestures or deflect responsibility. Professional complaint handling protects your business legally and commercially.
Most complaints fall into predictable categories: alleged faults present at sale, vehicles not matching their description, or issues arising shortly after purchase. Each category triggers different statutory remedies and burden-of-proof rules. Understanding which remedy the customer is entitled to, and when, determines how you should structure your response. A complaint about a fault discovered within 30 days requires a fundamentally different response to one raised after six months.
Step 1: Acknowledge Receipt and Gather Information Immediately
As soon as you receive a complaint, whether by email, letter, phone, or in person, acknowledge it within 24 hours. A prompt acknowledgement demonstrates professionalism and prevents the customer feeling ignored, which often escalates hostility. Your acknowledgement should confirm you have received the complaint, provide a reference number, and state when the customer can expect a substantive response.
During this initial contact, gather essential information: the customer's full name and contact details, vehicle registration and VIN, purchase date and mileage at sale, exact nature of the complaint, when the issue was first noticed, and whether the vehicle is still driveable. Ask the customer to provide photographs, independent inspection reports, or repair estimates if they have them. Document everything in writing, even if the initial complaint was verbal.
Retrieve your sales file immediately. You need the original advert, any pre-sale correspondence, the sales invoice, finance agreement if applicable, any warranty documents, and crucially, your pre-delivery inspection report and any vehicle history checks you conducted before sale. If you used comprehensive vehicle provenance data during your pre-sale checks, this documentation becomes vital evidence. Missing paperwork weakens your position significantly.
Check whether the complaint falls within the critical 30-day short-term right to reject period. If the customer purchased the vehicle fewer than 30 days ago and is alleging a fault present at sale, they have an automatic right to reject the vehicle and receive a full refund with minimal deductions. This timeline is strict and non-negotiable. Complaints received between 30 days and six months trigger different remedies, while those after six months shift the burden of proof to the customer.
Step 2: Investigate the Complaint Objectively and Thoroughly
Conduct an objective investigation before formulating your response. If the customer alleges a mechanical fault, arrange for a qualified technician to inspect the vehicle. This inspection must be genuinely diagnostic, not a search for reasons to reject the claim. Document the inspection findings with photographs, diagnostic printouts, and a written report. If the fault is intermittent or not immediately apparent, say so honestly rather than claiming no fault exists.
For complaints about vehicle description, compare the customer's allegations against your original advertisement, any verbal representations made during the sale, and the vehicle's actual specification. Factory build sheets and OEM data can prove what equipment was fitted as standard versus optional extras. If you described a vehicle as having manufacturer service history but it does not, or claimed it had never been in an accident when it had, you have mis-described it regardless of whether you knew the information was incorrect.
Consider whether the alleged fault could reasonably have been present at the point of sale. A major engine failure three days after purchase almost certainly existed at sale, even if symptoms were not obvious. A worn clutch that fails after 5,000 miles of heavy use may not have been. The six-month presumption rule is critical here: for faults appearing within six months of purchase, the law presumes the fault existed at sale unless you can prove otherwise. After six months, the customer must prove the fault was present when they bought the vehicle.
Review your pre-sale due diligence. Did you conduct adequate checks before offering the vehicle for sale? If you sold a vehicle with outstanding finance without checking, or missed a recorded insurance write-off, your position is weak regardless of whether the customer knew. If you conducted thorough checks using multiple data sources and the issue was genuinely undetectable, document this. Your pre-sale diligence affects both your legal liability and your moral standing.
Step 3: Determine the Appropriate Statutory Remedy
Once you understand the complaint and have investigated it, determine which statutory remedy applies under CRA 2015. The Act provides a tiered system of remedies that depends on timing and the nature of the breach. Getting this wrong in your response demonstrates either ignorance of the law or bad faith, both of which undermine your credibility.
If the complaint arrives within 30 days of purchase and the vehicle has a qualifying fault, the customer has the short-term right to reject. You must accept the return and provide a full refund, minus a reasonable deduction for use if the vehicle has covered significant mileage. Attempting to insist on repair instead of refund during this period breaches the customer's statutory rights. The only valid defences are that no fault exists, the fault was caused by the customer, or the fault was specifically drawn to the customer's attention before sale.
Between 30 days and six months, customers lose the automatic right to reject but gain the right to one opportunity for repair or replacement. You can choose whether to repair or replace the vehicle, provided your choice is not disproportionately costly compared to the alternative. The repair must be completed within a reasonable time and without significant inconvenience to the customer. Only if the repair fails or is impossible does the right to reject or claim a price reduction arise.
After six months, the burden of proof shifts. The customer must demonstrate that the fault existed at the point of sale, which usually requires an independent engineer's report. Your response should address whether their evidence meets this standard. Even if a fault exists, if it arose from wear and tear, misuse, or an event after sale, you are not liable. Understanding the burden of proof timeline is essential for structuring defensible responses to later complaints.
Step 4: Structure Your Written Response Professionally
Your written response should be clear, specific, and evidence-based. Open by acknowledging the customer's concerns and confirming you have investigated the complaint thoroughly. Avoid dismissive or defensive language. Even if you believe the complaint is unfounded, maintain a professional tone throughout. Aggressive or condescending responses frequently appear as evidence in court and reflect poorly on your business.
State your findings clearly. If your investigation identified a fault, explain what it is, what likely caused it, and when it probably arose. If you found no fault, describe what you checked and why you believe the vehicle is satisfactory. If the issue is intermittent, acknowledge this rather than implying the customer is mistaken. Provide copies of inspection reports, diagnostic results, or technical assessments that support your position.
Explain which remedy you are offering and why, with explicit reference to the relevant CRA 2015 provisions. If you are accepting a rejection claim, confirm the refund amount and deductions. If you are offering repair, specify what will be repaired, the expected timeframe, and what happens if the repair fails. If you are declining the complaint, explain your legal reasoning in plain English. Vague statements like "we do not accept liability" without explanation are professionally inadequate.
Include next steps and deadlines. If you are offering a remedy, state how long the offer remains open and what the customer needs to do to accept it. If you are declining the complaint, explain the customer's options: obtaining an independent inspection, seeking advice from Citizens Advice or Trading Standards, or pursuing alternative dispute resolution. Providing this information is not weakness; it demonstrates you understand the process and are operating transparently.
Step 5: Document Everything and Follow Through
Create a complete file of all complaint-related correspondence, inspection reports, photographs, and internal notes. If the complaint escalates to court or alternative dispute resolution, this documentation forms your defence. Courts expect dealers to maintain professional records. Missing documentation or inconsistent accounts damage your credibility significantly, even if your substantive position is correct.
If you have agreed to repair the vehicle, ensure the work is completed to a high standard within the promised timeframe. Provide the customer with a detailed invoice showing what was done, even if you are not charging them. Poor-quality repairs or repeated failures to fix the same fault strengthen the customer's case for rejection or price reduction. One opportunity to repair means exactly that under CRA 2015.
If you have agreed to a refund or rejection, process it promptly. Delays in returning money after accepting a rejection claim can lead to additional claims for consequential losses, such as hire car costs or finance interest. Calculate any use deduction transparently, showing your working. Arbitrary or excessive deductions frequently trigger disputes even when the rejection itself was accepted.
Follow up after resolution to confirm the customer is satisfied. A brief email or call checking that a repair has held or that a refund was received demonstrates professionalism and often prevents negative reviews. Many customers who complain are not inherently hostile; they simply want the problem fixed. Handling disputes professionally often converts a complainant into a neutral or even positive reviewer.
Common Mistakes That Escalate Complaints
Ignoring complaints or responding slowly is the most common error. Customers interpret silence as indifference or guilt. Even if you need time to investigate, acknowledge receipt immediately and provide regular updates. A complaint left unanswered for two weeks will almost certainly escalate to Trading Standards or online reviews.
Offering goodwill gestures instead of statutory remedies when a legal right exists is another frequent mistake. If a customer has a valid rejection right, offering a free service or minor repair instead is legally inadequate and often offensive. It suggests you are hoping they do not understand their rights. Always address the statutory position first, then consider goodwill if appropriate.
Blaming the customer without evidence damages your position. Claiming a fault was caused by misuse when you have no proof, or suggesting the customer is lying about when a problem appeared, creates hostility and looks defensive in court. If you genuinely believe customer misuse caused the issue, obtain expert evidence to support this before making the allegation.
Using warranty terms to avoid CRA 2015 obligations is both common and unlawful. Statutory rights under CRA 2015 cannot be excluded or limited by warranty terms, finance agreements, or sales conditions. Telling a customer their complaint is not covered by warranty when they have a statutory right to repair or rejection demonstrates either ignorance or dishonesty. Warranties supplement statutory rights; they do not replace them.
When to Seek Legal Advice or Expert Assessment
Some complaints require specialist input. If a customer alleges a serious safety defect, obtain an independent engineer's report immediately. Safety issues carry reputational and potential criminal liability beyond the civil dispute. If the alleged defect could affect other vehicles in your stock, investigate whether it is a batch issue.
When the facts are disputed and the financial exposure is significant, consider instructing a solicitor before responding. Legal advice is particularly valuable for complaints involving alleged misrepresentation, where what was said during the sale is contested, or complex technical issues where causation is unclear. A poorly worded response can constitute an admission or create additional liability.
If the customer has already obtained a legal opinion or independent inspection report, take it seriously. Dismissing expert evidence without obtaining your own expert rebuttal is rarely successful. Even if you disagree with the customer's expert, your response should engage with their specific findings rather than simply asserting they are wrong.
For high-value disputes or those involving unusual legal issues, the cost of legal advice is usually justified. Courts award costs against losing parties in many cases. Spending £500 on legal advice that helps you avoid a £5,000 judgment is sound business. Conversely, defending an indefensible position because you dislike the customer's tone is expensive pride.
Maintaining Professional Standards Throughout the Process
Your response to complaints reflects your business standards. Even if you ultimately disagree with the customer, a professional, evidence-based response demonstrates competence and good faith. Courts, trading standards officers, and online reviewers all assess how you handled the complaint, not just the outcome.
Train your staff on complaint handling procedures and CRA 2015 basics. The person who answers the phone or opens the email should know how to log the complaint properly and who to escalate it to. Inconsistent messages from different staff members undermine your credibility and frustrate customers.
Consider implementing a formal complaint handling procedure that documents each step, assigns responsibility, and tracks deadlines. Larger dealer groups often use case management systems; smaller dealers can achieve the same with a simple spreadsheet or dedicated email folder. The key is ensuring nothing falls through gaps and every complaint receives a timely, considered response.
View complaints as an opportunity to identify weaknesses in your processes. If you receive repeated complaints about vehicles with undisclosed faults, your pre-sale checking process is inadequate. If customers regularly allege verbal misrepresentations, your sales team needs training on accurate descriptions and the importance of documenting what was said. Patterns in complaints reveal systemic issues that damage your business if left unaddressed.
