Limited data — recalls on file
NHTSA has just 3 complaints on file for the 1978 BMW 320i — too few to judge reliability from owner reports alone — but 4 recall campaigns apply to this year, so any used example should have its VIN checked for completed recall work.

4 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
WHEN SUBJECTED TO THE EXTREMELY HIGH TEMPERATURES THAT CAN OCCUR IN THE ENGINE COMPARTMENT, THE DAMPER SLEEVES WHICH COVER THE RETURN SPRINGS OF THE ACCELERATOR CONTROL SYSTEM CAN DEFORM AND PREVENT THEIR RETURNING THE THROTTLE TO IDLE POSITION AFTER RELEASE OF THE ACCELERATOR PEDAL.
Remedy
DEALER WILL REPLACE THE THROTTLE RETURN DAMPER SLEEVES WITH NEW SLEEVES OF HIGH TEMPERATURE-RESISTANT PLASTIC MATERIAL.
Defect
THE HEX HEAD BOLT THAT CONNECTS THE MAIN WIRING HARNESS TO TERMINAL #30 MAY NOT HAVE BEEN TIGHTENED TO THE PROPER TORQUE.
Remedy
THE DEALER WILL REMOVE THE FUSE PANEL AND RETIGHTEN THE 5-MM HEX HEAD BOLT IN THE MAIN POWER TERMINAL UNDERNEATH THE FUSE PANEL, WITHOUT CHARGE TO OWNER.
Defect
DUE TO THE HIGH FUEL FLOW RATE IN THE FUEL SYSTEM, CONDITIONS OF EXTREME ALTITUDE, TEMPERATURES, OR FUEL CONTAMINATION, MAY LEAD TO THE FORMATION OF FUEL VAPOR BUBBLES.
Remedy
THE DEALER WILL INSTALL AN ADDITIONAL FUEL PUMP IN THE RIGHT SIDE OF THE FUEL TANK AT NO CHARGE TO OWNER.
Defect
DUE TO A MATERIAL STUCTURAL DEFECT, THE RUBBER SEAL BETWEEN THE METAL VALVE STEM AND RIM ALLOWS SLOW SEEPAGE OF AIR AROUND THE VALVE BASE.
Remedy
THE DEALER WILL REPLACE DEFECTIVE METAL TIRE VALVE STEMS AND RUBBER SEALS WITH NEW ONES, AT NO COST TO THE CUSTOMER.
