Complaints: What, Where, and By When
You may submit complaints exclusively through the complaint form in your CarOnSale account. If you pick up the vehicle yourself, you have 9 business days from the date of purchase; if the vehicle is delivered by a carrier, you have 3 business days from the date of delivery. You may file a complaint regarding damage that is not listed in the condition report, is not normal wear and tear, and costs more than €300 (net) to repair.
By when do I have to file a complaint?
All deadlines are counted in business days, meaning Monday through Friday, excluding public holidays in Berlin.
For deliveries, the form will open as soon as the shipping carrier marks the vehicle as delivered in your account. Once the deadline has passed, we can no longer process claims. Therefore, please inspect the vehicle immediately upon pickup or delivery.
When making a purchase, you can extend the return period for €29 per auction. You'll find this option in the auction details; the extended period will be displayed when you place your order.
List of Damages: What Types of Damages Can Be Claimed?
These examples are not exhaustive.
Everything you need to know at a glance.
Where do I file a complaint?
In your CarOnSale account, under “My Purchases,” you’ll find your completed purchases. Vehicles for which you can still file a complaint have their own button there. Any complaints you’ve started but haven’t yet submitted can be found under “Complaints.” We cannot process complaints submitted via email, phone, or through “My Inquiries.”
What can I file a complaint about?
- Damage that is not listed in the condition report and is not normal wear and tear, provided the repair costs more than €300 net. This limit applies to each instance of damage; multiple minor instances of damage are not added together.
- Incorrect vehicle information in the listing: date of first registration, number of previous owners, odometer reading, VIN, fuel type, transmission type, emissions class, and whether a vehicle inspection report and service manual are available.
If the vehicle's registration details—such as the date of first registration, previous owners, mileage, or transmission type—do not match, you do not need to pick up the vehicle first. Please contact us immediately via "My Inquiries."
What can't I file a complaint about?
- Normal signs of wear and tear consistent with the vehicle's age and mileage
- Damage with repair costs of up to €300 net (minor damage)
- Wear parts such as tires, brakes, and the clutch
- Technology not covered by the COSCheck: engine and turbocharger; batteries in electric and hybrid vehicles; multimedia, navigation, and driver-assistance systems
- Missing accessories such as a warning triangle, first-aid kit, floor mats, or onboard tools
- Equipment information sourced from the DAT database
- Discrepancies that were already apparent from the photos of the vehicle documents in the ad
The COSCheck is a visual inspection that does not include a test drive. The vehicles are sold without the statutory warranty. Claims filed through CarOnSale apply only to damage not listed in the condition report.
What information do I need to file a complaint?
- Type of damage, such as a scratch or dent
- Expressive photos and a video
- A photo of the odometer reading
- A brief description of the damage
- For shipments by carrier: a copy of the CMR waybill
- If required for the inspection: a copy of the vehicle registration documents, if you already have them
If there is any visible damage or missing accessories upon delivery, note this directly on the waybill. Do not have the damage repaired until CarOnSale has given its approval.
What happens after I submit my application?
We process complaints in writing; you can check the status under “My Inquiries.” If the complaint is valid, CarOnSale will decide whether to repair the damage, provide an appropriate reduction in the purchase price, or rescind the sale. The team often offers a credit that will be applied to your next auction fee.
