Registry statistics describe submitted records and do not establish manufacturer-wide incidence or failure rates. In production these figures bind to sanitized database aggregates.

WHY THE REGISTRY EXISTS

Individual complaints disappear. Documented records accumulate.

An evaporator failure is diagnosed one owner at a time, paid for one invoice at a time, and dismissed one service visit at a time. The Registry preserves each case as verifiable evidence — dated, documented and hashed — so the pattern becomes measurable.

Records are gathered to a standard useful to regulators, researchers, journalists and — should one form — qualified counsel in a future proceeding.

HOW RECORDS ARE VERIFIED →
THE FAILURE PATTERN

How HVAC evaporator failure typically presents

01
Uneven cooling
Driver side cools while the passenger side blows warm — the most frequently reported first sign.
02
Progressive capacity loss
Cooling weakens over weeks or months rather than failing at once.
03
Repeated recharges
R-1234yf recharges restore cooling temporarily; the refrigerant escapes again.
04
Leak traced to the evaporator
Dye or electronic detection locates the leak at the evaporator core, sealed inside the HVAC box behind the dashboard.
05
Dashboard-out replacement quote
Reaching the core requires removing the dashboard — labor dominates a four-to-five-figure estimate.

THE RECHARGE CYCLE

A recharge restores cooling for a season. The leak remains.

Keep every recharge invoice — repeat service visits are part of the documentary record.

THE COST OF A DASHBOARD-OUT REPAIR

A component the size of a briefcase. A repair priced like an engine.

Because the evaporator sits at the center of the HVAC assembly, replacement requires dashboard removal. Founder-case figures, from dealer documents on file:

How records are verified

FULL METHODOLOGY →
A
Document-verified

Repair orders, invoices or diagnostic reports on file. Files are hashed on upload; originals preserved unaltered; published copies are redacted derivatives.

B
Partially documented

Some documentary support — photos, partial invoices or correspondence — with remaining details owner-attested.

C
Owner-attested

Reported without documents. Counted separately and never blended into verified statistics.
