8.5.5.1/8.5.5.2IATF 16949:2016

Service feedback & service agreements (IATF only)

Plain-language summary

Information from service must flow back into manufacturing and design (including analysis where the customer requires), and where you have a service agreement with the customer, its centres must meet the agreed requirements.

What the clause is really asking

Ensure a process for communicating service-concern information to manufacturing, engineering and design activities — service failures are design and process data. With customer service agreements: verify the relevant service centres comply.

What auditors look for

Auditors ask how field/service issues reach your FMEA and control plan reviews, sample a recent field concern through the loop, and where service agreements exist, check the verification of service centre compliance.

Typical evidence

Field concern reports flowing to engineering; FMEA updates from service data; service agreement compliance checks.

How to comply — recommendations

Route every field concern through the same intake as customer complaints, with one extra mandatory field: 'FMEA/control plan reviewed?'. The loop, evidenced.

Common nonconformities

Service issues handled commercially with no technical feedback; FMEAs never updated from field data; service agreement obligations unverified.
