OEMTRONIC AUTO PARTS

Limited Warranty Policy

Effective Date: 1st January 2026

OEMtrONIC Auto Parts ("OEMtronic," "we," "us," or "our") sells quality-tested used and recycled automotive parts, including engines, transmissions, and other vehicle components.

Because used automotive parts have previously been installed and operated in vehicles, all warranty coverage is subject to the terms, conditions, installation requirements, and exclusions contained in this Warranty Policy.

By purchasing a part from OEMtronic, the original purchaser acknowledges that they have read and agreed to this Warranty Policy.

---

STANDARD LIMITED WARRANTY

Unless a different warranty period is specifically stated on the customer's invoice or purchased as an extended warranty, OEMtronic provides a 90-day limited warranty beginning on the date the part is delivered to the customer.

The warranty applies only to the original purchaser and is not transferable.

The warranty is limited to defects covered by this policy and does not constitute a guarantee that a used part will be free from normal wear, cosmetic imperfections, or differences associated with previously used automotive components.

If a covered defect is confirmed, OEMtronic's remedy may include, at OEMtronic's discretion:

• Repair of the defective component;

• Replacement with a comparable part;

• Replacement of the defective component or assembly; or

• Refund of the purchase price when repair or replacement is not reasonably available.

OEMtronic will determine the appropriate remedy after reviewing the warranty claim and any required diagnostic or inspection information.

---

WHAT THE WARRANTY COVERS

Subject to the conditions and exclusions in this policy, the warranty generally covers a covered mechanical failure of the primary used component sold by OEMtronic.

For engines, warranty coverage generally applies to the internal engine assembly and covered mechanical defects.

For transmissions, warranty coverage generally applies to the transmission assembly and its ability to operate and shift properly.

For other parts, coverage is limited to the specific component and warranty terms stated on the applicable invoice or product listing.

The warranty does not guarantee cosmetic condition.

Surface rust, scratches, dents, discoloration, paint differences, normal wear, or other cosmetic imperfections that do not prevent the part from performing its intended function are not considered warranty defects.

---

ENGINE WARRANTY

Unless otherwise stated on the invoice, used engines are covered for 90 days from the delivery date.

Warranty coverage for an engine is generally limited to covered internal mechanical failure of the engine assembly.

Covered conditions may include, where applicable:

• Internal mechanical failure;

• Rod knock;

• Cracked engine block;

• Excessive internal mechanical failure;

• Excessive smoking resulting from a covered internal defect.

OEMtronic does not warrant cosmetic condition or the condition of accessories attached to the engine.

The engine may have been sold with accessories for convenience or to facilitate installation. Accessories and external components are generally not covered unless specifically identified as covered on the invoice.

Examples of components that may not be covered include:

• Alternators;

• Starters;

• Compressors;

• Power steering pumps;

• Fuel injection components;

• Carburetors;

• Intake and exhaust manifolds;

• Sensors and switches;

• Wiring and electrical components;

• Distributors;

• Throttle bodies;

• Turbochargers and intercoolers;

• Water pumps;

• Oil pans;

• Timing covers;

• Pulleys;

• Belts;

• Tensioners;

• Idlers;

• Flexplates;

• Flywheels;

• Emissions equipment; and

• Other external accessories or components.

The customer or installer is responsible for determining which original components should be transferred to the replacement engine.

---

ENGINE INSTALLATION REQUIREMENTS

To maintain warranty eligibility, the replacement engine must be installed correctly by a qualified professional automotive repair facility.

---

TRANSMISSION WARRANTY

Unless otherwise stated on the invoice, used transmissions are covered for 90 days from the delivery date.

The transmission warranty generally covers proper operation and shifting of the transmission under normal use.

The warranty does not cover failure resulting from improper installation, abuse, incorrect fluid, inadequate maintenance, overheating, modification, or failure of related vehicle systems.

Customers must not ship a warranty part to OEMtronic without authorization.

Unauthorized shipments may be refused or returned at the customer's expense.

---

---

HEAT TABS AND TAMPERING

Where a heat tab or other tamper-evident device has been installed on an engine or other component, it must remain intact.

A melted, removed, damaged, or intentionally altered heat tab may be evidence of overheating or tampering and may result in denial of the warranty claim.

OEMtronic reserves the right to inspect the component and determine whether overheating or tampering contributed to the failure.

---

• Transmission fluid;

• Transmission filters;

• Coolant;

• Belts;

• Hoses;

Customers are responsible for providing accurate information, including:

• VIN;

• Year;

• Make;

• Model;

• Engine size;

• Transmission type;

• Drive configuration;

• Part number, where applicable; and

• Other requested vehicle information.

OEMtronic is not responsible for fitment problems resulting from inaccurate, incomplete, or incorrect information supplied by the customer.

Where OEMtronic confirms fitment based on the correct VIN and vehicle information supplied by the customer, the applicable fitment terms on the order will apply.

---

EMISSIONS AND SMOG REQUIREMENTS

OEMtronic does not guarantee that a used engine, transmission, or other automotive component will comply with the emissions, smog, inspection, or environmental requirements of every state or jurisdiction.

Customers are responsible for determining whether a replacement part is legal and suitable for use in their jurisdiction.

The customer should verify applicable state and local emissions requirements before purchasing or installing a replacement component.

---

USED PART CONDITION

All used and recycled automotive parts are previously used components.

The part received may have:

• Surface rust;

• Scratches;

• Dents;

• Paint differences;

• Signs of previous use;

• Minor cosmetic imperfections; or

• Other characteristics associated with recycled automotive parts.

These conditions do not automatically constitute a warranty defect.

Warranty coverage concerns the functional and mechanical condition of the covered component as specified in this policy.

---

WARRANTY REPLACEMENTS

If OEMtronic approves a warranty replacement, the replacement part will generally be of comparable type and function.

Because used parts are dependent upon inventory availability, the replacement may not be identical in:

• Mileage;

• Appearance;

• Color;

• Manufacturing date;

• Accessory configuration; or

• Other non-functional characteristics.

OEMtronic may provide a comparable replacement when the original part is unavailable.

Only the defective covered component is subject to replacement unless OEMtronic determines that replacement of the complete assembly is appropriate.

---

RETURN OF DEFECTIVE PART

When OEMtronic authorizes a warranty replacement, the original part may be required to be returned.

The customer must:

• Follow OEMtronic's return instructions;

• Use the assigned authorization or RMA number;

• Return the part within the specified period;

• Keep the part complete;

• Avoid further disassembly or modification; and

• Package the part appropriately for shipment.

Failure to return a required warranty part may result in cancellation of the warranty replacement or other charges permitted by the applicable order terms.

---

REFUNDS

A refund is not automatically available for every warranty claim.

OEMtronic's primary warranty remedy is repair or replacement of the covered defective part.

If repair or replacement is not reasonably available, OEMtronic may issue a refund in accordance with the applicable order and warranty terms.

Refunds generally apply to the purchase price of the covered part and do not include labor, installation, diagnostic, towing, rental, storage, or other incidental expenses unless expressly agreed in writing.

---

EXTENDED WARRANTIES

Certain products may qualify for an extended warranty.

If an extended warranty is purchased, the applicable warranty period and coverage will be stated on the product listing, checkout page, invoice, or warranty documentation.

An extended warranty generally extends the duration of coverage and does not automatically expand the types of failures covered by the standard warranty.

Unless specifically stated otherwise, all standard warranty exclusions and installation requirements continue to apply during the extended warranty period.

---

LABOR WARRANTY

A labor warranty is separate from the standard parts warranty.

If a labor warranty is purchased, its:

• Coverage period;

• Mileage limitations;

• Labor rate;

• Maximum reimbursement;

• Eligible repair facility requirements;

• Claim procedures; and

• Other limitations

will be determined by the labor warranty purchased and shown on the applicable invoice or warranty documentation.

A labor warranty does not apply unless it was specifically purchased or otherwise provided in writing by OEMtronic.

---

COMMERCIAL, FLEET AND SPECIAL USE

Commercial, fleet, industrial, high-mileage, heavy-duty, racing, performance, towing, or other special applications may have different warranty requirements.

OEMtronic may impose additional requirements or limitations for these applications.

Customers should obtain written confirmation of applicable warranty coverage before purchase when a part will be used for a special application.

---

CORE POLICY

If a core charge applies to an order, the core must be returned in accordance with the terms stated on the customer's invoice or order confirmation.

Core returns must generally be complete and reasonably comparable to the core for which the charge was assessed.

The customer may be responsible for shipping or other costs associated with returning a core unless otherwise stated in writing.

---

NO COVERAGE FOR CONSEQUENTIAL DAMAGES

To the maximum extent permitted by applicable law, OEMtronic's responsibility under this limited warranty is restricted to the remedies specifically described in this policy.

OEMtronic is not responsible for indirect, incidental, special, or consequential losses arising from the failure or use of a purchased part, including, where legally permissible:

• Loss of use;

• Lost income;

• Lost profits;

• Business interruption;

• Towing;

• Rental vehicles;

• Transportation;

• Diagnostic expenses;

• Installation expenses; or

• Other incidental costs.

Nothing in this Warranty Policy is intended to exclude or limit any rights or remedies that cannot legally be excluded or limited under applicable law.

---

WARRANTY IS LIMITED TO THE ORIGINAL PURCHASER

Unless otherwise required by applicable law or expressly stated in writing, the warranty applies only to the original purchaser named on the invoice.

The warranty may not be transferred, resold, assigned, or transferred to another vehicle or owner without written authorization from OEMtronic.

---

CHARGEBACKS AND PAYMENT DISPUTES

If a customer initiates a payment dispute or chargeback relating to a transaction, OEMtronic may suspend warranty processing, returns, replacements, or refunds associated with that transaction until the payment dispute is resolved.

Customers should contact OEMtronic directly before initiating a payment dispute whenever possible so that OEMtronic has an opportunity to investigate and resolve the issue.

This provision does not limit any rights the customer may have under applicable law.

---

INSPECTION RIGHTS

OEMtronic reserves the right to inspect a part before approving a warranty claim.

Inspection may include:

• Visual inspection;

• Mechanical inspection;

• Diagnostic testing;

• Disassembly by an authorized party;

• Review of installation records;

• Review of maintenance records; or

• Inspection by a qualified technician.

A warranty claim may be denied if inspection establishes that the failure resulted from an excluded condition.

---

WARRANTY CLAIM DECISION

OEMtronic will review submitted documentation and determine whether the claimed failure appears to fall within warranty coverage.

OEMtronic may request additional documentation or inspection before making a final determination.

Submitting a warranty claim does not guarantee approval.

If a claim is denied, OEMtronic may provide the reason for the denial based on the information available at the time of review.

---

CUSTOMER RESPONSIBILITY AFTER A FAILURE

If a vehicle develops a serious mechanical problem, warning light, overheating condition, loss of oil pressure, loss of transmission fluid, unusual knocking, grinding, or other significant symptom, the customer should stop operating the vehicle when reasonably safe to do so.

Continuing to operate a vehicle after a serious mechanical warning may cause additional damage that is not covered by this warranty.

---

PARTS SOLD "AS IS"

Parts specifically identified on the invoice or product listing as being sold "AS IS," with no warranty, are not covered by this Limited Warranty unless otherwise required by applicable law.

Any specific warranty stated on the customer's invoice or order confirmation will control where it expressly differs from this general policy.

---

OEMtronic is an independent automotive parts seller.

Vehicle manufacturer names, trademarks, logos, model names, and other marks displayed on OEMtronic.com are used for identification, compatibility, and informational purposes.

OEMtronic is not affiliated with, sponsored by, or endorsed by the vehicle manufacturers whose products may be referenced on the website unless expressly stated otherwise.

---

OEMtronic may update or revise this Warranty Policy from time to time.

The warranty terms applicable to a particular purchase will generally be determined by the warranty terms in effect and provided to the customer for that transaction, subject to applicable law.
