Good evening, everyone.


I recently acquired a 2014 E220 to drive a few miles. The vehicle appeared to be mechanically sound and was in excellent condition, particularly considering its 124,000 mileage.

I had my vehicle evaluated by my normal technician. As anticipated, a few standard consumables need attention; nevertheless, he indicated that the rear subframe is severely damaged, advising that it should only be driven if sent to Mercedes for repairs.

He advised presenting it to them, as he has encountered several clients with the same problem, one of whom received a complimentary replacement merely months prior.

I visited Sytner Northampton, where the staff were exceedingly accommodating and consented to conduct an examination a few days later, therefore I entrusted them with the vehicle.

Upon inspection, they provided a video indicating that the subframe was severely rusted with perforations and required replacement.

A few days later, they informed me that Mercedes had declined to fund any of the repairs due to the absence of warranty coverage.

I received an email for them and contacted their support directly, who ultimately consented to a 50% 'goodwill gesture' contingent upon a waiver of liability and a confidentiality agreement, despite my objections that this constitutes a clear manufacturing defect, resulting in a hazardous vehicle and components that have deteriorated prematurely.

Their assertion is that the decision is conclusive, and my sole option is to engage with the Motor Ombudsman. Can anyone advise on the appropriate approach or suggest a more advantageous line of action?


Thank you very much

Was this noted in prior MOT examinations?

A check of the forum will yield numerous instances of subframe corrosion necessitating replacement. Mercedes has agreed to replace several items at no cost or to contribute to the expenses; nevertheless, it is crucial to recognise that this does not constitute a guarantee and is solely an act of goodwill on their behalf.


An offer to subsidise fifty percent of the expense is likely the most favourable proposal available, as Mercedes has recently been less accommodating in this regard.

They might convincingly assert that the car is over 11 years old and that they bear no responsibility for any components of that age.

Did you purchase privately or from a dealer? If the latter is the case, you possess certain legal recourse.

Taunton During my auto inspection last year, Mercedes informed me that if the vehicle had exhibited rust, they would replace it at no cost. It appears that the outcome is contingent upon the service provider, suggesting an element of chance.

The car was acquired privately and lacks any reference to this on prior MOT records; yet, it is my understanding that it is not uncommon for such damage to remain undetected until it manifests significant problems.

Although I acknowledge the absence of warranty or liability on their part, the pervasive nature of this issue over a certain range of models indicates a definitive manufacturing flaw. Therefore, I want guidance on the most effective approach to capitalise on this scenario.


I have reviewed posts on multiple platforms indicating that MB has become less forthcoming with complete replacements recently, but I understand that it still occurs in certain instances.

Is there merit in raising this matter to an Ombudsman? Has anyone before attempted this, and if so, what was the outcome?

While I comprehend your frustration, discussing manufacturing faults is unlikely to be beneficial. No recall exists, allowing MB to contend that the problem may stem from the vehicle's prior maintenance, as not all cars experience this issue. In the absence of a government recall, I fail to discern the appropriate avenue for a claim to the ombudsman.

Obtain a quotation from an independent provider for replacement, as non-Mercedes subframes are available. This option is likely to be more economical, and you will have the satisfaction of not compensating Mercedes.

When was the car last subjected to a MOT inspection?

Greetings, Purchased a 2010 E350 CDI estate last February, accompanied by a complete Mercedes service history. It failed its MOT a few weeks ago due to the sub-frame, and the independent Mercedes dealer promptly stated it will be addressed free of charge. They ought to produce a 2014 model without hesitation. Contact many primary dealers until you identify one ready to undertake the task.

If you have just purchased it from a dealer, you own a claim against the seller, as it is unable to serve its intended function as a vehicle. Review the Consumer Rights Act.
