NUVIO Kaizen Label
The NUVIO Kaizen Label method
A private label with a public method. NUVIO audits the Car Assist partner garages on 7 areas and 100 points, then checks every improvement: that is the Kaizen spirit, continuous improvement.
Audited. Transparent. Improving every day.

Customer satisfaction
Ratings are collected only by NUVIO, on WhatsApp or by phone, from customers referred by Car Assist, a few days after the repair. A rating is always tied to a real referral. The mean is published from 10 ratings over 12 months. Comments are never published.
Continuous improvement
The garage fixes a point, sends its evidence to the NUVIO Garage Hotline on WhatsApp, a NUVIO technician checks it, and the garage's page is updated. Validated improvements stay visible with their date.
Independence
The level depends only on verified evidence. It cannot be bought: NUVIO never requires buying equipment, training or parts, including from its partners, to progress. When equipment is recommended, at least two market options are named. A network brand shown on a page is a verified fact, not a partnership with NUVIO.
Validity and checks
The label is valid for 12 months and is renewed by an annual on-site audit. NUVIO may run spot checks and mystery-shopper visits. The garage has a 7-day right of reply on any finding; a second NUVIO technical profile decides.
Method versions
Method v1 (October 2026): grid v1 of the Car Assist partner programme. Any change creates a new version shown on every garage page. (Method v1)
Private NUVIO label; it does not replace a regulatory certification. The valid status is the one shown online.
NUVIO checks organisation, equipment and transparency criteria on a given date; the garage alone is responsible for the work it does.
Frequently asked questions
Is the NUVIO Kaizen Label an official certification?
No. It is a private NUVIO label that does not replace any regulatory certification. Its method is public and every result is dated.
Can a garage pay for a better level?
No. The level depends only on evidence checked by NUVIO. No purchase is required to progress.
What does « To improve » mean?
A point the garage can still improve. It is not a failure: the label values verified progress.
How can I check that a certificate is genuine?
Scan the QR code of the certificate displayed in the garage's office, or type its number (NUV-LK-…) on the check page.
