The 1979 Datsun 510 has 3 recalls, the most serious being a front seatbelt retractor that can jam, leaving front passengers unable to buckle their seatbelts at all.
The retractor's plastic damper can disengage from the emergency locking mechanism, causing the belt to seize in place rather than extend and latch. On hatchback models, the tail and brake lamp sockets may not be firmly pressed into their plastic housings, which can break the ground circuit and cause the brake lights or taillights to go dark, making the car harder for following drivers to see. The third recall is a compliance matter: certain vehicles left the factory with weight rating labels showing load limits in pounds rather than the kilograms required under Canadian regulations.
