The 1978 Porsche 928 has 3 recalls, the most serious involving several chassis and brake defects that can affect vehicle control, including cracked front suspension adjusters that cause wheel misalignment and rear brake hoses that can twist, chafe, and leak.
The front suspension issue is worth taking seriously: if the caster and camber adjusters crack and loosen, the wheel alignment shifts in ways the driver may not notice until handling feels vague or uneven. The rear brake hoses can also suffer damage from chafing against nearby components, which can lead to brake fluid loss and reduced stopping power. A separate concern involves the emergency brake cable, which may have been routed incorrectly and can wear through from rubbing. The cruise control switch can also stick and render the speed control system inoperative. On the steering side, the universal joint connecting the steering shaft to the rack may be improperly positioned, and extended driving on rough roads can work it loose, producing excessive free play in the steering wheel. The third recall is a compliance issue: certain vehicles carry certification labels that are missing the required production date under Canadian safety regulations.
