A warranty is only worth what you can prove. A final drive fails at hour 4,200, well inside the coverage window on paper, and the claim still gets denied because nobody can produce the last three service records. The most critical piece of documentation is arguably the detailed maintenance log that includes dates, machine hours, specific work performed, and the types of fluids and parts used, and without it, an OEM has every reason to argue the failure was neglect instead of a defect.
Tracking warranty coverage means logging in-service dates, service intervals, and repair documentation for every machine so claims can be filed inside the OEM's window with the right evidence attached. OEMs reject claims on missing evidence more often than on actual ineligibility. Sign up for FleetRabbit to track warranty status across your fleet automatically, or book a demo to see how it prevents missed claims.
Why Warranty Claims Get Denied
Most denials have nothing to do with whether the part actually failed. They come down to documentation and timing.
Incomplete Maintenance Records
If you cannot prove you followed the recommended service intervals, the manufacturer can argue the failure was due to neglect, even when the part failed on its own.
Missed Pre-Authorization
Most heavy-duty OEMs require pre-authorization for repairs above a dollar threshold, and performing the repair first and seeking reimbursement later usually results in a denied claim.
Filed Outside the Window
Claims typically must be filed through the OEM's portal within a prescribed window, usually 30 days from repair completion and sometimes as short as 7.
Operating Outside Specifications
Using a machine outside its rated operational envelope, like hammering concrete with an excavator built for soil excavation, is treated as misuse rather than a covered defect.

What You Need on File to Win a Claim
Approval usually comes down to whether the paperwork tells a clean, complete story from purchase to failure.
Purchase and Installation Records
Original purchase receipts and installation records establish exactly when coverage began.
Complete Maintenance Logs
Every oil change, filter swap, and greasing interval, dated and tied to machine hours at the time of service.
Failure Documentation
Photographs of the failed component in place and recorded fault codes from the diagnostic scan at the time of failure.
Odometer or Hour-Meter Reading
The in-service date and last preventive maintenance interval, recorded at the moment of the claim.
The Claim Window: Timing Is Everything
Get Pre-Authorization Before Repair Begins
Pre-authorization confirms the OEM's approved parts list and labor time allowance before the technician starts work.
Capture Evidence at the Work Order Level
Digital capture at the work order level, rather than retrospective document hunting, converts most marginal claims into approved ones.
File Inside the OEM's Deadline
Submit through the manufacturer's portal well before the 7 to 30 day window closes, since a late filing is treated the same as no claim at all.
Appeal With Evidence If Denied
If maintenance logs contradict a neglect claim, that documentation can be submitted as counter-evidence in a formal appeal.
Not All Coverage Is the Same
| Coverage Type | What It Includes | What to Watch For |
|---|---|---|
| Parts-Only | Cost of the replacement part itself | Labor is often excluded and should never be assumed to be included |
| Parts and Labor | Part cost plus technician time | May be capped at a set number of hours or hourly rate |
| Rebuilt Component Warranty | Coverage on professionally rebuilt parts | Terms may differ from new-part coverage even with proper testing and quality control |
| Transferable Warranty | Coverage that carries over to a new owner | Depends entirely on the specific warranty policy, so confirm before resale |
