How do I return an item?

Parts Warranties
For all warranty returns, malfunction of the part in question must be verified by ReInvent The Wheel, or documentation provided by a licensed professional and verified by RTW.

New Genuine Mercedes-Benz Parts come with a two-year manufacturer's warranty. Mercedes warranties the part only, not the labor (unless it is performed at a Mercedes dealership). If the part malfunctions, you will need proof of defect from a licensed professional. You will be responsible for sending the part back to us, and we will confer with Mercedes on your behalf.

Used Electrical Parts: 30-day Warranty
We offer a standard 30-day warranty on all electrically-operated parts, beginning the date of delivery. This covers all electrically-operated items from failure and from defects that were not described in the item description. Customer is responsible for returning the item to us. Upon receipt of tracking information we will ship an equivalent replacement item or, if a replacement is not available, refund the full cost of the item and shipping costs.


 Used Mechanical Parts: 60-day Warranty
We offer a standard 60-day warranty on all items, beginning the date of delivery. This covers all mechanically-operated items from failure and from defects that were not described in the item description. Customer is responsible for returning the item to us. Upon receipt of tracking information we will ship an equivalent replacement item or, if a replacement is not available, refund the full cost of the item and shipping costs.

Used Engines & Transmissions: 90-day Warranty
All engines & Transmissions, unless noted otherwise in the item description, include a 90-day warranty. This covers all mechanical and electrical components of the engine or transmission but does not include accessory systems (air conditioning, cruise control, etc.). Customer must be able to verify proper installation and maintenance of the item up until date of the claim. Upon malfunction we will send an equivalent replacement component as soon as available; if a replacement component is not available within 30 days we will send a partial refund equivalent to replace that component. The cost of labor is not included in this warranty. Please also note that reduced performance is not included in this warranty, as you are purchasing used parts and they will perform as such.

Rebuilt Parts: 180-day Warranty
Unless a longer warranty is explicit in the item's description, all rebuilt parts include a 180-day warranty, with terms as above.

Rebuilt Motors: One-Year Warranty
ReInvent the Wheel warrants our rebuilt motors for one year, commencing on the date of delivery, subject to the following terms and conditions.
Under the terms of this warranty ReInvent The Wheel will repair or replace the motor and/or its components without charge to the original owner. We reserve the right to determine whether a repair or replacement is necessary. We shall not be liable for the cost of labor for removal or installation of the motor unless performed at our facility, nor for any service not explicitly covered by this warranty policy.
Customer must be able to verify proper installation and maintenance of the item up until date of the claim, including proof that proper maintenance was performed during the break-in period. We will provide guidelines for the proper maintenance and break-in that are based on those set by Mercedes-Benz. The customer is responsible for reviewing and following these guidelines as well as documentation of the break-in and maintenance. Upon malfunction of any individual component, we will send an equivalent replacement component as soon as available; if a replacement component is not available within 60 days we will send a partial refund equivalent to replace that component.
Motor damage caused by any of the following shall void this warranty:
-failure of accessory components not included with the rebuilt motor.
-performance modifcations to the fuel system or turbocharger.
-disassembly or separation of the longblock.
-failure to change fluids at appropriate intervals, maintain proper fluid levels, or any other action that does not comply with our recommended guidelines.
