Last updated: August 18, 2026

This policy applies to all products and services purchased from MAKS Enterprises, including those sold through MAKS TIPM Rebuilders, MAKS ECM Rebuilders, and affiliate marketplaces.

1. Warranty coverage

Every product we sell — new, rebuilt, pre-owned, and repair services — carries a 1-year limited warranty against defects in MAKS materials and workmanship. Coverage begins on the date your order is delivered and runs for one year. Extended coverage of up to 3 years total is available for purchase at checkout.

Within the warranty period, MAKS will repair or replace a defective item as set out in this policy. The warranty covers integral failures of the item we supplied.

The warranty is non-transferable. It covers the original purchaser and the vehicle the unit was first installed in. It does not pass to a subsequent owner if the vehicle is sold, and it does not follow the unit into a different vehicle.

We do not offer lifetime coverage.

2. Choice of remedy

Within the warranty period, MAKS will assess your unit and repair or replace it.

• During the first 90 days after delivery, if a defect is found, the choice is yours: MAKS will repair the item, or — if you would rather have a replacement — we will send a compatible rebuilt unit as an advance replacement under section 7 (or, for a pre-owned purchase, a compatible pre-owned unit).
• After the first 90 days, MAKS will evaluate the item and, at our discretion, either repair it or supply a compatible replacement unit.

The 90-day point does not shorten or end your warranty. Your coverage is one full year from delivery either way. The only thing that changes at 90 days is who selects between the two remedies — you, or MAKS.

Repeat issues. Your first warranty replacement is covered. If a further issue arises within the warranty period, MAKS will continue to repair or replace the unit under this section; advance replacement is limited to one per module per vehicle, so a subsequent claim is handled as a standard replacement (section 7).

Replacement warranty. If a product is replaced under warranty, the replacement is covered for 90 days from the date of exchange, or for the remainder of the original warranty period, whichever is longer.

3. What is not covered

This warranty does not cover:

• Improper installation, or use outside the manufacturer’s specification
• Accidents, misuse, neglect, or unintended use
• Modifications, unauthorized repair, or removal and reinstallation into another vehicle
• Electrical shorts, corrosion, or water intrusion
• Damage caused by external systems or components not supplied by MAKS — sensors, harnesses, grounds, batteries, or other vehicle-side faults
• Wear of peripheral parts not serviced by MAKS
• Powersports, off-road, or racing applications where the part was not intended for that use
• Environmental conditions, including natural disasters

MAKS is not liable for indirect, special, incidental, or consequential damages. Labor, diagnostic charges, towing, rental-car costs, and other incidental expenses are the customer’s responsibility and are not reimbursed. No other warranties, express or implied, are made, including implied warranties of merchantability or fitness for a particular purpose.

4. Starting a claim or a return

For every return other than a core, you must contact customer service first to obtain a return authorization. Returns sent without an authorization cannot be processed and may be refused or returned at the sender’s expense.

Have your original order number ready. We will confirm eligibility, issue the authorization, and send return instructions. Returns must ship within 14 days of the authorization being issued, and no later than the deadline stated in your authorization.

For electrical complaints, we will ask you to complete a short troubleshooting checklist before we authorize a warranty replacement — a hard and soft reset, battery voltage, harness and ground inspection. This is not required for a physically damaged unit.

5. Returns and refunds

Return window. Eligible products may be returned within 30 days of delivery, subject to the exclusions in this policy.

A unit becomes used the moment it is installed. An installed unit does not qualify for a standard return — it is handled under the rental terms in section 6.

Unopened and never installed. A unit that is verified unopened and uninstalled may be returned, including after the 30-day window at our discretion. Mark the box “NEVER INSTALLED” with your order or ticket number.

Unwanted, incorrect, or non-defective returns. Where the unit is not defective, the refund is the purchase price less round-trip shipping. If you refused delivery, you receive a full refund with no shipping deduction.

Cancellations. You may cancel for a full refund at any time before your order ships.

Testing with no fault found. MAKS tests every unit returned for warranty service. If testing finds no defect related to the issue you reported, the unit is returned to you and we refund your cost less a $110 diagnostic fee. Where no fault is found, round-trip shipping is the customer’s responsibility.

Physical damage. A unit that has been installed and returned with physical damage — a defaced or cracked housing, broken tabs, damaged connectors — is not eligible for a full refund, regardless of how the damage occurred. We will inspect it and offer repair or replacement where the fault is ours. Where a courtesy refund is granted, documented repair and replacement-part costs are deducted following teardown.

Cash refunds are provided where neither a repair nor a replacement is possible, and in the specific circumstances set out in this policy.

Refund timing. Approved refunds are issued to the original payment method within 5 business days of inspection and approval. Core and warranty-return refunds generally complete within 7–9 business days. Where a refund to the original card is not possible, we will issue a check.

Repair fees are refundable only where: a unit was submitted for testing or diagnosis and no repair was performed (refund less the $110 diagnostic fee); a repair we performed has failed twice on re-repair; or we are unable to complete the repair.

6. Rental returns — converting a purchase

You have 30 days from delivery to convert a purchase into a rental and send the module back in its original box. This is how an installed unit is returned. After 30 days the rental route is closed and warranty service under section 2 is the remedy.

The rental period begins on the date the module is delivered to you and ends on the date you ship it back, per carrier tracking.

Rates

	Covers the first 10 days	Each additional day
Rebuilt units	$120 one-time fee	$12 per day
New units	25% of the module’s value	$18 per day

The rental period is capped at 30 days maximum, and the total charge will never exceed the module’s full retail price. The rental fee is deducted from your refund.

• Return shipping is the customer’s responsibility, as is providing the return tracking number.
• The module must come back in the condition it was received. It is inspected on return, and additional charges may apply for damage or missing components.
• If the module is not returned within the agreed period, MAKS may charge its full retail value, less any rental fees already paid.
• Rental conversion is subject to MAKS approval based on the unit’s condition, timing, and usage.

Rental refund exception. The rental cost is refunded in full if you provide either a receipt from a repair shop or dealership showing that replacing the unit resolved your vehicle’s issue, or documentation that the unit was diagnosed as defective, or proof that you purchased a replacement from a dealership. Documentation is required; we cannot waive the rental charge on a verbal account alone.

7. Warranty replacement types

Advance replacement (rebuilt units only). We ship a replacement before your original unit arrives.

• Limited to one per module per vehicle. Subsequent claims are handled as a standard replacement.
• On marketplace orders, a $1 pre-authorization is required to initiate the request.
• Your original unit must be returned within 30 days. If it is not, the payment method on file will be charged the full retail value of the unit we sent.

Your core is separate. A warranty replacement does not cancel the core you owe from your original purchase. These are two different modules — the original unit from your vehicle, and the MAKS unit we are replacing — and both are due back to us. Returning one does not settle the other.

Standard replacement (new and rebuilt units). You send your unit in first. We test it on receipt and repair or replace it as needed. If no fault is found, shipping both ways is your responsibility.

8. Exchanges

Where an exchange is authorized, we ship the correct part.

• Where a unit has already been sent to you, it must be returned within 30 days. If it is not, the payment method on file will be charged the full retail value of your original order — not the difference in price between the two parts.
• Where you request the exchange before your original order has shipped, no unit has been sent to you, so only your core is due back.
• Where the exchange is due to a customer ordering error, shipping is the customer’s responsibility.
• If the correct part costs more, the difference is charged. If it costs less, the difference is refunded.

Your core is separate. An exchange does not cancel the core you owe from your original purchase. It remains due back under section 9.

9. Core returns

Core charges are covered by our Core Return Policy. In short: there is no upfront core charge and no buyback. Return your old module within 30 days using the prepaid label and there is nothing further to pay. If it is not returned in time, the payment method on file is charged the core fee for that module type. Cores are accepted in any condition.

International orders. We do not charge a core fee on an order shipped outside the United States unless we have arranged a return route with you in advance. Where return shipping is practical we may provide a prepaid label and ask for the core back; where it is not, the core is waived and nothing further is owed. We will never charge an international customer a core fee without first providing a workable way to return it.

10. Shipping

• Standard shipping within the United States is free. Expedited shipping is available for an additional fee.
• On an in-warranty defect, MAKS pays shipping both ways. A prepaid return label is provided on request for continental US customers.
• Where testing finds no fault, shipping both ways is the customer’s responsibility.
• International customers are responsible for all shipping costs, duties, and fees.
• MAKS is not liable for delivered packages that are subsequently lost or stolen. If a package arrives damaged, send us photographs and we will file the carrier claim on your behalf and replace or refund.

11. Purchases made through eBay, AutoZone, and other marketplaces

Your 1-year warranty is the same regardless of where you bought the unit. However, returns for marketplace purchases must follow that marketplace’s own return process and cannot be processed through the direct-site process described here. Contact us and we will point you to the right route.

12. Changes to this policy

This return policy is subject to change; however, the version in effect at the time of your purchase will apply to your order.
