Limited data — recalls on file
NHTSA has just 0 complaints on file for the 1977 Porsche 911 — too few to judge reliability from owner reports alone — but 2 recall campaigns apply to this year, so any used example should have its VIN checked for completed recall work.

NCAP overall
2 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
ON THE INVOLVED VEHICLES, THE IDENTIFICATION OF THE FUNCTIONS OF THE AUTOMATIC SPEED CONTROL SYSTEM WAS OMITTED. THIS FAILS TO COMPLY WITH FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 101, "CONTROLS AND DISPLAYS".
Remedy
A PLASTIC IDENTIFICATION LABEL WILL BE PERMANENTLY AFFIXED TO THE INSTRUMENT PANEL.
Defect
THE INSTALLATION OF THE VPC AIR CONDITIONER REQUIRES REPLACEMENT OF THE STANDARD HEATER HOSE WITH A SPECIAL HOSE. THIS HOSE MAY HAVE BEEN PUSHED TOO FAR INTO THE HEAT EXCHANGER AND MAY COME INTO CONTACT WITH THE EXHAUST PIPE.
Remedy
DEALER WILL REPLACE THE ALUMINUM-PAPER-ALUMINUM HOSE WITH AN ALL-ALUMINUM HOSE WITHOUT CHARGE TO OWNER.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 2 recalls should be verified as completed.
