EXCHANGE AND WARRANTY POLICY — CTS (CAR TUNING STAR)

Last updated: September 29, 2026

SUMMARY

  • 30 days: it works or we exchange it. If the part fails, or if we confirmed it was compatible and it isn't, we exchange it for the same part or the right one.
  • If you ordered the wrong part on your own, there is no exchange or return: that's why we confirm compatibility for free before you buy.
  • 12-month warranty against manufacturing defects.
  • We do exchanges, not money refunds (except where the law requires it).

1. 30-DAY GUARANTEE: IT WORKS OR WE EXCHANGE IT

It applies to every CTS product: harnesses, bench cables and adapters. If within 30 days of delivery the product:

  • doesn't work because of a defect, or
  • isn't compatible with the truck, engine or computer (ECM), when CTS confirmed compatibility before the purchase based on the information you gave us,

we exchange it for an identical unit or for the right model for your vehicle. If the right model has a different price, we quote the difference before making the exchange.

To qualify, the product must come back:

  • with no cuts, splices or modifications;
  • with its label or serial number;
  • complete and properly packed.

2. WHO PAYS SHIPPING FOR THE EXCHANGE

  • If the fault is CTS's (manufacturing defect, or compatibility we confirmed that turned out wrong): CTS pays the return shipping with a prepaid label and the shipping of the new unit.

Part ordered by customer error: if you bought without checking with us, or gave us the wrong information (VIN, engine serial number, ECM label), and the part doesn't fit your truck, there is no exchange or return.

That's why we recommend checking compatibility before you buy: send us a photo of the ECM label or the engine serial number on WhatsApp (+1 346-340-4684). It's free, no strings attached.

3. 12-MONTH WARRANTY AGAINST MANUFACTURING DEFECTS

All our products carry a 12-month warranty against manufacturing defects, counted from the ship date. If within that period the product has a failure caused by its manufacturing (continuity, crimping, terminals, materials), we replace it with a new or repaired unit of the same specification at no cost to you.

4. PRODUCT RECEIVED DEFECTIVE OR DAMAGED IN TRANSIT

Check your order when it arrives. If it arrives defective or damaged in transit, let us know within the first 48 hours with your order number, the serial number or SKU marked on the product, and photos of the product and the packaging. We replace it at no cost once the case is verified.

5. WHAT IT DOESN'T COVER

  • Change of mind when the product works and is compatible
  • Parts ordered by customer error: without confirming compatibility with CTS, or with the wrong information
  • Damage from incorrect installation or connections outside the supplied diagram
  • Modifications, cuts or splices made to the product by third parties
  • Damage caused by external failures: defective ECM, sensors, vehicle short circuits, overvoltage or reversed polarity
  • Wear from undeclared extreme operating conditions
  • Products bought outside official CTS channels

6. HOW TO REQUEST AN EXCHANGE OR WARRANTY

  1. Message us on WhatsApp (+1 346-340-4684) or email info@cartuningstar.com with your order number, the serial number and what's happening, with photos or a video.
  2. Our technical team reviews the case. We may ask for extra checks, such as continuity measurements or photos of the installation.
  3. If it qualifies, we tell you how to send the part back and ship you the new or the right unit.

7. CONSUMER RIGHTS

This policy does not limit any non-waivable rights the law of your country or state gives you as a consumer.
