Warranty Coverage

Every Omniflash PCM is backed by a 5-year warranty starting the day your unit is delivered. No registration. No paperwork. Your order number is all we need.

• Manufacturing defects
• Programming errors on our end
• Internal component failures under normal operation
• Communication failures with the vehicle
• VIN-matching issues caused by us

• Damage from improper installation
• Water, fluid, or moisture damage
• Physical damage from impact, dropping, or tampering
• Issues caused by underlying vehicle problems (failed sensors, wiring shorts, alternator failures, etc.)
• Modifications or repair attempts by anyone other than Omniflash
• VIN errors caused by incorrect information provided at order

If your PCM fails within 5 years, we'll replace it. Fast.

1. Have a certified mechanic diagnose the issue
2. Reach out to our warranty team via email or chat with your order number and the diagnostic findings
3. We respond within 1 business day
4. Approved claims ship a replacement within 1 to 2 business days
5. Return the defective unit using the prepaid label included with your replacement (within 30 days)

Warranty claims result in replacement units, not refunds. The original 5-year warranty period continues. Replacements do not restart the clock.

Warranty is non-transferable and applies only to the original purchaser.

Defective units must be returned within 30 days of replacement delivery using the prepaid label we provide. Failure to return may result in charges equal to the replacement value.

All warranty claims require a certified mechanic's diagnosis confirming the PCM as the failure point. This protects you from unnecessary part swaps and protects us from claims caused by other vehicle issues.

Common misdiagnoses we see:

Failed crank sensors, faulty ignition coils, bad ground connections, dying batteries. A proper diagnostic catches these before you order a replacement.
