If your Mercedes has developed major faults, you have rights under UK consumer law to reject the vehicle and obtain a refund or unwind your finance. Our dedicated team at Stormcatcher Law specialises in Mercedes rejection claims, with a strong history of achieving successful resolutions for a host of models, from the GLS and EQB to the Mercedes S-Class and C-Class Saloon.
Specialist Legal Support for Mercedes Complaints
Mercedes-Benz has built its reputation on luxury, engineering precision, and technological innovation. However, when reliability issues arise, owners often find these problems uniquely complex and expensive to address. Mercedes rejection claims require a specialist legal approach due to the technical sophistication of these vehicles and the intricate relationship between buyer, dealer, and finance company.
We regularly see cases involving persistent or hard-to-diagnose faults, from engines and gearboxes to advanced driver-assistance technology. Even authorised Mercedes workshops can struggle to identify intermittent or software-related defects sometimes, and repair costs can quickly escalate as a result. Our services cover vehicles purchased from official Mercedes-Benz retailers or independent dealers, as well as those acquired through finance or leasing. Whether the issue has appeared within the first few months or after repeated unsuccessful repair attempts, we can assist.
Your Legal Rights and Grounds for Rejection
Under the Consumer Rights Act 2015, any vehicle sold must be of satisfactory quality, fit for purpose, and accurately described. If that’s not been the case for you, you have the strongest right to reject the vehicle within the first 30 days of purchase. If a fault appears between 30 days and six months, the law presumes it existed at the time of sale unless the dealer can prove otherwise. After six months, rejection is still possible but may require stronger evidence that the issue was present or developing when you bought the car.
In the case of serious or recurring faults that affect the safety, performance, or value of the car, especially if they’ve been expensive to repair or unresolved after several attempts, you’ll have even stronger grounds for rejection. When a rejection is upheld, the finance agreement is “unwound.” The finance company must refund your deposit and all payments made, while you return the car. You are further protected under the Consumer Protection from Unfair Trading Regulations 2008, which safeguard buyers from misleading or unfair dealer practices.
What Our Customers Are Saying
Common Mercedes Faults
Our experience with Mercedes rejection cases shows consistent fault trends across multiple models and generations. Engine and gearbox issues are among the most severe, particularly timing chain problems, excessive oil consumption, and gearbox hesitation or failure.
Diesel engines:
Diesel engines frequently suffer from DPF (Diesel Particulate Filter) and EGR system faults, leading to warning lights, loss of power, or limp mode, and Mercedes vehicles are no exception.
Electrical faults:
Electrical and software malfunctions are also widespread, often affecting infotainment, safety sensors, and driver-assist features like adaptive cruise control and lane-keeping systems.
Other reported issues:
Other reported defects include air suspension failures, steering column noises, malfunctioning parking sensors, and premature corrosion or paint defects. Each of these issues undermines the vehicle’s reliability and can justify a legal rejection claim.

How the Process Works
We begin by carrying out a detailed case review, assessing your vehicle’s history, documentation, and fault evidence. Once you instruct us, we issue a formal rejection notice setting out your legal position, the identified defects, and the reasons these amount to breaches under the Consumer Rights Act.
If necessary, we may also commission an independent engineer’s report from a Mercedes-trained specialist to support your claim. Most cases reach a successful settlement through negotiation, though we can escalate to the Financial Ombudsman Service or County Court where required.
Essential evidence includes your purchase or finance documents, service and repair records, diagnostic reports, MOT certificates, photos or videos of faults, and all communication with the dealership.
While some claims conclude within weeks, more complex cases, particularly those involving finance, can take several months. For cash purchases, you can claim a full refund of the purchase price. In the case of a finance agreement, you’ll be able to recover all payments, deposits, interest, and fees, as well as the cost of repairs or alternative transport. Dealers sometimes propose deductions for vehicle use, but we’ll challenge excessive claims, especially when faults existed from the outset.
