Limited data — recalls on file
NHTSA has just 0 complaints on file for the 1977 Audi 100 — too few to judge reliability from owner reports alone — but one recall campaign applies to this year, so any used example should have its VIN checked for completed recall work.

NCAP overall
1 NHTSA recall campaign on file. Recall repairs are free at franchised dealers.
Defect
THE INVOLVED VEHICLES MAY NOT COMPLY WITH FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 105, "HYDRAULIC BRAKE SYSTEMS". LABELS INSTALLED ON BRAKE FLUID RESERVOIRS MAY NOT CONTAIN THE REQUIRED BRAKE FLUID WARNING TEXT. LACK OF THIS INFORMATION MAY LEAD TO THE USE OF IMPROPER BRAKE FLUID WHEN THE BRAKE SYSTEM IS SERVICED.
Remedy
OWNER WILL BE SENT THE CORRECT LABEL FOR SELF-INSTALLATION OR, IF PREFERRED, INSTALLATION BY THE DEALER.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 1 recall should be verified as completed.
Yes — NHTSA lists 1 recall campaign affecting the 1977 Audi 100. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
Based on NHTSA ODI data through June 2026. Complaints are consumer-reported and unverified. Updated July 5, 2026.
