Warranty
Fleet warranty claims: stop paying for repairs that were covered
Most fleets pay for some repairs that a warranty would have covered. Not because the claim was refused, but because nobody knew the part was still under warranty when the invoice was paid. Recovering that money is a record-keeping job: know what is covered, until when, and on which vehicle.
Two kinds of warranty to track
| Vehicle warranties | Component (fitted part) warranties | |
|---|---|---|
| Examples | Base vehicle, powertrain, engine, transmission, emissions system, body | Replacement alternators, starters, turbochargers, batteries, tires, remanufactured units |
| Who stands behind it | The vehicle or major component manufacturer, often through its dealer network | The part maker or the supplier who sold it |
| Where the terms live | The warranty booklet delivered with the vehicle, and any extended coverage bought later | The invoice, the box, or the supplier's published terms |
| Why it gets lost | Coverage is split across several makers with different limits | The part moves with the vehicle, but the paperwork stays in a parts file, if anywhere |
Component warranties are the ones fleets lose most easily. A replacement part fitted eight months ago may still be covered when it fails again, but only if someone can connect the failure to that part, that invoice and that vehicle.
Coverage ends by time, distance or hours: whichever comes first
Commercial vehicle warranties commonly end at a date, a mileage or engine-hours limit, or whichever of these comes first. The terms differ by maker and by component, so read each warranty rather than assuming. To know whether a repair is covered you need three facts on the day of the failure:
- The start date of the coverage (often the in-service or delivery date, not the purchase date).
- The vehicle's odometer or engine-hour reading at the start, for a part fitted after delivery.
- The vehicle's current reading.
Without current readings, a distance limit cannot be checked, which is one more reason to record them regularly; see preventive maintenance schedules.
Why claims are missed
- The repair is done before anyone checks. A busy shop fixes the vehicle and gets it back on the road; the warranty question comes up later, if ever.
- The failed part was thrown away. Many claims require the failed part to be kept or returned.
- The work was done by the wrong shop. Some warranties require repairs at an authorized dealer or with the maker's approval first.
- Maintenance cannot be proven. A maker may ask for service records showing the vehicle was maintained to its schedule. Gaps in the maintenance file weaken the claim.
- The deadline passed. Claims often have to be filed within a set time of the failure or the repair. Check each warranty for its own deadline.
What to record when a part or vehicle is covered
| Field | Why it matters |
|---|---|
| Vehicle (unit number and VIN) | Ties the coverage to the vehicle it travels with |
| Part description, part number and serial number | Proves the failed part is the one that was covered |
| Supplier or maker, and where the terms are | Tells you who to claim from and under what rules |
| Start date and start reading | The base for time and distance limits |
| End date and distance or hour limit | So a repair can be checked against coverage in seconds |
| Original invoice | Proof of purchase, usually required |
A claim checklist
- Before the repair: check whether the vehicle or the failed part is under warranty, and whether the maker requires authorization or an authorized shop.
- Keep the failed part, tagged with the vehicle, date and work order, until the claim is settled.
- Record the failure: the symptom, the reading at failure, photos, and any fault codes.
- Attach the original purchase invoice and the repair invoice.
- Attach maintenance records that show the vehicle was serviced to schedule.
- File within the warranty's deadline and note the supplier's claim reference.
- Record the outcome: accepted with the amount recovered, rejected with the reason, or withdrawn.
Measure what you recover
Track every claim to its outcome. The total recovered over a year, and the reasons for rejected claims, show whether the process works. Repeated rejections for missing maintenance records point to the records, not the supplier. Recovered amounts should also reduce the repair cost you report for that vehicle; see maintenance cost per mile.
Cargovate records warranties on vehicles and on the serialized parts fitted to them, flags work orders that may be covered, and records each claim with its outcome; you send the claim to the supplier yourself. For the terms used here, see the glossary.
