What the 3 Cs are — and why reviewers live by them
Every line on an RV warranty, arrival (DAF) or PDI claim is built on the same three parts. Some manufacturers call the first one the Concern instead of the Complaint; the logic is identical.
The reviewer reads them in order and asks one question at each step. Complaint: is this a real, specific problem? Cause: is it a defect in factory materials or workmanship — something the manufacturer owns? Correction: is the requested repair the right fix, at a fair amount of time? A clear yes three times is an approval. A shrug at any step is a cut, a request for information, or a denial.
The Cause is where most lines live or die, because it is where coverage gets decided. A line that never says why the failure is the manufacturer’s responsibility has quietly asked the reviewer to assume the worst.
How to write each C
Specific, factual, and in the reviewer’s language.
Complaint: the symptom, exactly as observed
Where, what and when. “Water leaks out at the bottom of the wall when the water pump runs” beats “plumbing leak.” Location plus behavior plus the condition that triggers it.
Cause: the factory defect behind it
Name the failed part or process and tie it to materials or workmanship: “supply fitting behind faucet not tightened at factory,” “sealant missing at upper corner of window frame.” Never leave it blank, and never write “unknown” if the tech found it.
Correction: the repair you need authorized
The specific steps and the verification: “access rear of faucet, tighten supply fitting, pressurize system, verify no leak.” Include parts with part numbers, and request the time the job actually takes.
Write it as an authorization request, not a finished job
Manufacturers treat warranty and arrival claims as pre-authorization requests: you are asking permission to make a repair at their expense. Lines written in the past tense — “replaced,” “resealed,” “fixed” — read as work done without authorization, and that alone can sink them.
Write the Complaint and Cause as what was detected, and the Correction as the repair requested: “Request authorization to reseal…”, “Replace jack (P/N …) — authorization requested.” Same facts, wording the reviewer can approve.
Before and after: two real lines
Anonymized from actual dealer claims. Same repair, very different odds.
Simple line — weak version
Complaint: shower leaking. Cause: — . Correction: fixed leak, 1 hr. → No location, no cause, past tense. Expect a request for information or a denial.
Simple line — version that gets paid
Complaint: Shower faucet leaks from the back when the water system is pressurized. Cause: Supply fitting at rear of faucet not tightened at factory (workmanship). Correction: Access rear of faucet, tighten supply fitting, pressurize system and verify no leak — authorization requested, 1.0 hr. Photos: water at wall base (wide), fitting location (close-up).
Complex line — weak version
Complaint: water in slide. Cause: seals. Correction: redo slide floor, 80 hrs. → A big number with nothing under it. Expect it cut or denied.
Complex line — version that gets paid
Complaint: Water entering at all four corners of the bedroom slide-out; slide-out floor soft when walked on. Cause: Corner seals and sealant not adequately applied at factory, allowing water into the slide-out floor structure (moisture readings and corner photos attached). Correction: Remove slide-out room, replace water-damaged floor decking, reinstall, replace corner seals and sealant, water-test — authorization requested; labor breakdown by step attached.
Words that hand the reviewer a denial
Accurate on the shop floor, dangerous on a claim. Describe the defect and its factory cause instead.
“Rotted,” “rusted,” “corroded,” “worn”
These describe time and environment, not manufacturing. On a young unit they invite a maintenance or exposure denial. Describe the defect (“seal not bonded at corner”) and the resulting damage separately.
“Broken,” “damaged,” “cracked” with no cause
Without a factory cause, these read as impact or misuse. Say what failed and why: “bracket weld incomplete,” “panel not fastened at top edge.”
“Customer says,” “customer states”
Fine as the source of a Complaint, never as the evidence for a Cause. The Cause must come from the tech’s inspection.
“Unknown,” “TBD,” or blank
A blank Cause is an open invitation to deny. If diagnosis is still needed, request diagnostic time as its own line.
Match the depth to the problem
Not every line deserves an essay. A bubbling decal, a loose cabinet back or a door out of adjustment needs two clean sentences and a before photo — anything longer slows the reviewer down and buries the facts.
Water intrusion, structural, slide-out and roof lines are different. They carry the biggest dollars and the most scrutiny, so they get the full story: what was found, how it was confirmed, why it is a factory defect, and a step-by-step labor breakdown that justifies the time requested.
If your shop writes repair notes in French (or any language other than the manufacturer’s), translate the meaning, not the words. A tech’s shorthand like “tout mangé” translated literally becomes “eaten” or “corroded” — which reads as wear. Rewrite it as the defect it actually is.
Rule of thumb from our claim files: if a reviewer who has never seen the unit can read the three sentences, look at the photos, and understand what is wrong, why it is the factory’s problem and what fixing it takes, the line gets paid.

Complaint, Cause, Correction — FAQ
What are the 3 Cs of a warranty claim?
Complaint (or Concern), Cause and Correction. The Complaint describes the symptom, the Cause identifies the factory defect behind it, and the Correction describes the repair being requested. Each claim line needs all three.
Is it Complaint or Concern?
Both are used — some manufacturers and shops say Concern, others Complaint. They mean the same thing: the problem as observed or reported.
How long should a Complaint, Cause, Correction be?
As long as the issue requires and no longer. Simple cosmetic or hardware lines can be one sentence each. Water intrusion, structural and slide-out lines need a full narrative and a labor breakdown.
Should I write the correction in the past tense?
No. Manufacturers generally treat claims as pre-authorization requests, so write the Correction as the repair you are requesting authorization for, not as work already completed.
Why was my labor time cut?
Usually because the Correction did not justify it. List the actual steps the repair requires — removal, access, replacement, reinstall, testing — and support them with photos. A bare number is easy to cut.
