Retail Lifetime Warranty
Eligible CGSULIT TPMS sensors purchased by retail consumers directly from CGSULIT US LLC are covered by a lifetime warranty against manufacturing defects, subject to the conditions and exclusions set out in this policy.

The lifetime warranty applies for as long as the original retail purchaser owns the product and uses it in the vehicle for which it was originally programmed, provided the defect is a genuine manufacturing fault present at the time of manufacture.

The lifetime warranty is available only to the original purchaser and is not transferable to a subsequent owner of the vehicle or the product. It does not cover the product for the life of any particular vehicle, nor does it guarantee that the sensor will remain compatible with future vehicle software updates, ECU firmware changes, or changes in regulatory TPMS frequency requirements.

Wholesale and Trade Warranty
The CGSULIT TPMS sensors supplied to wholesale accounts, trade customers, resellers, automotive workshops, tyre retailers, and bulk purchasers are covered by a 2-year warranty against manufacturing defects from the date of purchase, unless a written trade agreement, formal invoice, or product page clearly specifies a different warranty period for that specific supply arrangement. If you are a trade customer and are uncertain whether your account is classified as a wholesale or retail arrangement, please contact sales@cgsulit.com before placing your first order.

What Is Covered Under This Warranty
Our warranty covers eligible products against manufacturing defects — meaning faults that originated during the design, component selection, or production process and were present in the product at the time it left our warehouse. A manufacturing defect is a condition that causes the product to fail to function as described under normal use, and which is not attributable to any action, inaction, or circumstance arising after the product left our possession.

Covered — TPMS Sensors
1. Internal sensor electronics failure: 

Failure of the internal pressure transducer, temperature sensor, signal transmitter, or processing chip that causes the sensor to stop transmitting data or to transmit inaccurate data, where no external physical damage is present, and the sensor has been correctly installed and programmed.

2. Battery failure within expected service life: 

Premature and unexpected depletion of the internal battery within the warranted period, provided the vehicle has been driven under normal conditions, and the battery depletion is not attributable to extended storage in extreme temperature conditions or improper programming cycles.

3. Defective housing or seal integrity:

Failure of the sensor body caused by defective moulding, bonding, or sealing at the time of manufacture that results in moisture ingress or structural failure of the casing, provided the sensor has not been subject to impact, tyre removal equipment damage, or improper valve torque.

4. TPMS protocol transmission faults: 

Failure of the sensor to transmit on its designated radio frequency protocol as specified on the product listing, confirmed after independent inspection by our technical team, where the fault is attributable to a manufacturing-stage component fault rather than a vehicle-side receiver or ECU issue.

5. Sensor verified faulty after inspection: 

Any sensor fault confirmed as a manufacturing defect by our technical team following physical inspection or diagnostic testing, regardless of whether the specific failure mode is listed above, provided it does not fall within the exclusions stated in Section 04 of this policy.

Warranty Remedy
If your warranty claim is assessed and approved by our technical team, CGSULIT US LLC will, at our reasonable discretion and in accordance with the A,erican Consumer Protection Law, provide one of the following remedies:

1. Replacement: 

We will supply a replacement product of the same or equivalent specification at no cost to you. Replacement products will be dispatched via standard shipping at no charge to the customers. 

2. Repair:

Where practical, we may arrange repair of the defective product. This option is more commonly applicable to programming tools than to sensors, where replacement is typically faster and more practical.

3. Refund: 

In circumstances where neither repair nor replacement is reasonably available within a reasonable timeframe, we will offer a full or partial refund depending on the nature and extent of the failure.

Our warranty remedies are offered in addition to, and do not limit, your rights under the American Consumer Protection Law. If your product has a major failure, you are entitled under the ACPL to choose between a replacement, refund, or compensation for the reduction in value — and we will honour that entitlement fully.

What Is Not Covered — Warranty Exclusions

The following circumstances, conditions, and causes of failure are excluded from warranty coverage. These exclusions do not affect your statutory rights under the American Consumer Protection Law in cases where a product has a major failure or fails to be of acceptable quality regardless of cause. However, where the cause of the fault can be clearly attributed to one of the following circumstances, no voluntary warranty remedy will be provided.

Important: These exclusions apply only to our voluntary warranty. They do not override your non-excludable rights under the American Consumer Protection Law or equivalent consumer protection legislation. If you believe a statutory consumer guarantee applies to your situation regardless of the exclusions below, please contact us to discuss your specific circumstances.

How to Make a Warranty Claim — Step-by-Step Process
We have made our warranty claim process as straightforward as possible. Please follow the steps below to submit your claim efficiently. Providing complete and accurate information at the outset allows us to assess your claim promptly and avoid unnecessary delays.

All warranty claims must be submitted directly to CGSULIT US LLC — we do not accept claims submitted through third-party workshops or resellers on behalf of the original purchaser without prior written authorisation.

1. Gather Your Proof of Purchase
Locate your original order confirmation email, tax invoice, or receipt issued by CGSULIT US LLC. Your order number is located on all correspondence from us and begins with a unique reference code. If you cannot locate your original invoice, contact us with the email address used to place the order, and we can retrieve your purchase history.

2. Document the Fault with Photos or Video
Before removing or returning the sensor, take clear photographs of the installed sensor, the valve stem, the wheel, and any visible damage or indication of the fault. If the fault is an intermittent TPMS warning light on the vehicle's dashboard, a photograph or short video showing the warning light will also assist our assessment. Photos should be taken before any further workshop work is carried out on the wheel.

3. Contact Our Warranty Team by Email
Send your warranty claim to support@cgsulit.com with the subject line "Warranty Claim – [Your Order Number]". Include your full name, contact phone number, order number, the product part number (found on sensor body), your vehicle make, model, build year, and VIN (where available), a description of the fault and when it first appeared, and all photographs or video documentation of the issue. For diagnostic tool claims, also include the tool's serial number and the current firmware version displayed on the tool.

4. Warranty Assessment by Our Technical Team
Once we receive your claim, our technical team will assess the information provided within 2–5 business days. In some cases, we may request that you return the defective product to our warehouse for physical inspection before a warranty remedy is confirmed. We will provide a prepaid return label for the customer in cases where the claim is assessed as likely valid. For minor or straightforward claims where the fault is clearly evident from the documentation, we may be able to approve the claim without requiring the product's return.

5. Receive Your Warranty Remedy
Once your claim is approved, we will arrange a refund or dispatch a replacement product via express shipping at no additional cost to you. We will send a dispatch confirmation and tracking number to your registered email address. If a replacement is not available (for example, if the specific model has been superseded), we will contact you to discuss an equivalent alternative or a refund.

6. Warranty Claim Requirements — Information Checklist
To allow our team to assess your warranty claim as efficiently as possible, please ensure you include all of the following information in your initial warranty email. Incomplete claims will require follow-up correspondence, which may extend the overall processing time. The more detail you provide upfront, the faster we can resolve your claim.

Required Information for All Warranty Claims
- Your full name and contact phone number

- Your order number or original invoice from CGSULIT US LLC.

- Your vehicle make, model, year of manufacture, and VIN (Vehicle Identification Number) where applicable

- A clear description of the fault — what the product is doing or not doing, when the issue first occurred, and whether it is persistent or intermittent

- Photographs of the sensor, valve, and wheel — including any visible damage or unusual conditions

Additional Requirements for Programming Tool Claims
- The serial number of the tool (found on the back of the device or in the tool's settings menu)

- The current firmware version displayed on the tool at the time the fault was identified

- A description of the specific function or feature that has failed and the steps you took that led to the failure

- Whether the tool has been updated, reset, or connected to any third-party device or software since purchase.

Returning Products for Warranty Assessment
Not all warranty claims require the physical return of the defective product. In many cases — particularly for straightforward sensor faults supported by clear photographic evidence — our technical team can approve a warranty remedy without requiring you to return the product.

However, in cases where the fault is not clearly evident from documentation alone, or where we need to conduct a physical inspection to determine whether the defect is a manufacturing fault or an installation or usage issue, we will request that you return the product to us.

Return Authorisation Process
Do not return any product without first receiving written authorisation from our team. Unrequested returns may cause delays in processing and may be returned to you at your cost. Once our team has assessed your claim and determined that a physical return is required, we will provide you with a prepaid return shipping label. 

Vehicle Compatibility, Programming, and Installation — Warranty Responsibilities

Correct vehicle compatibility, proper installation, and correct programming are all essential requirements for TPMS sensors to function as intended and for warranty coverage to apply. CGSULIT US LLC provides detailed vehicle compatibility information upon customers' request and direct technical support via phone and email.

Customers are strongly encouraged to verify compatibility before purchasing and to seek confirmation from our team if they have any doubt.

Installer Responsibility
If your sensors are installed by a third-party workshop, tyre fitter, or automotive service centre, that installer is responsible for ensuring correct fitment procedures are followed. CGSULIT US LLC is not liable for damage caused by incorrect tyre fitting practices, over-torquing, valve damage, or programming errors made by third-party installers.

If you experience a TPMS fault following a professional installation, we recommend first asking your installer to verify their installation procedure and programming steps before lodging a warranty claim with us.

Programming Verification Before Claiming
Before submitting a warranty claim for a sensor that is not communicating with your vehicle, please verify the following steps have been completed, as incorrect programming is the most common cause of sensor communication failures and is not covered by warranty:

The correct TPMS relearn, or OBD programming procedure has been completed for your specific vehicle make, model, and year using the procedure of the relearn guide.

The sensor has been programmed to the correct frequency (315 MHz or 433 MHz) and protocol for your vehicle's TPMS receiver

All four sensors have been installed, and the vehicle has been driven for at least 15 minutes above 25 km/h to allow the TPMS system to complete its initialisation cycle.

The TPMS warning light has not simply been triggered by a low tyre pressure condition rather than a sensor fault — inflate all tyres to the manufacturer's recommended pressure and drive for 15 minutes to check whether the warning clears.

Our dealers listed on our website are trusted TPMS installation centres that provide free sensor programming, cloning, installation, and relearning. Our technical team is also available to walk you through the correct programming and relearning procedure for your specific vehicle before you proceed with a warranty claim.

Many TPMS warning light issues can be resolved with guidance rather than a product replacement. Please email support@cgsulit.com before assuming a warranty fault exists.

Product Quality Assurance and Testing Standards

All CGSULIT TPMS sensors supplied by CGSULIT US LLC are manufactured to OE-equivalent quality standards and are required to meet the following performance and compliance benchmarks before being stocked and offered for sale. Our commitment to product quality underpins our confidence in offering a lifetime retail warranty on our TPMS range.

Compliance and Testing Standards
- Radio frequency compliance:

All CGSULIT sensors operating at 315 MHz and 433 MHz are manufactured and tested to comply with applicable radio frequency regulations in the markets in which they are intended for use, including radio communications regulations and equivalent standards in the relevant destination markets.

- Pressure and temperature accuracy: 

Sensors are factory-calibrated and tested to ensure that pressure readings are accurate to within the specification stated on the product listing under standard operating conditions, and that temperature reporting is consistent with the vehicle's expected tyre operating temperature range.

- Sealing and ingress protection: 

All CGSULIT sensor housings are sealed and tested for resistance to moisture, dust, and tyre operating fluid environments, ensuring reliable operation over the sensor's rated service life under normal driving conditions.

- Battery service life testing: 

Internal batteries used in CGSULIT sensors are selected for consistent, long-duration performance. Each sensor model's expected battery service life is tested and stated on the product specification, giving customers a clear understanding of the replacement cycle they can expect.

- Ongoing Quality Monitoring
CGSULIT US LLC monitors warranty claim data across all product lines on an ongoing basis. Where we identify a higher-than-expected rate of claims on a specific batch or product variant, we will investigate the cause and — if a systemic manufacturing issue is identified — we will proactively contact affected customers to offer remedies, regardless of whether those customers have already submitted a formal claim. This proactive approach reflects our genuine commitment to product quality and customer confidence.

Warranty Interaction with Returns and Refund Policy
Our Warranty Policy and our Returns and Refund Policy are separate documents with different purposes, but they work together to protect your rights as a customer. The relationship between the two is as follows:

Returns Policy:

Governs the circumstances in which you may return a product for a refund, exchange, or store credit — including change-of-mind returns (subject to the conditions stated in that policy), incorrect orders, and products that are incompatible with your vehicle.

Warranty Policy (this document):

Governs claims for product defects, manufacturing faults, and failures under normal use — situations where the product itself has a problem, rather than a change of mind or an ordering error.

Consumer Guarantees:

Operate as a separate, non-excludable layer of rights that sit above both our voluntary warranty and our returns policy. These statutory rights entitle you to a remedy from us regardless of what our voluntary policies say, provided the statutory conditions for a remedy are met.

If you are unsure whether your situation is best addressed under our Returns Policy or this Warranty Policy, please contact our team, and we will direct you to the most appropriate process. You will never be sent in a circle between policies — our team will make a clear determination and provide you with a straightforward path to resolution.

You do not need to identify the specific policy that applies to your situation before contacting us. Simply describe your issue clearly, and our team will identify the correct process and remedy that applies to your circumstances under both our voluntary policies and your statutory rights.
