1 recall across 1 model year
The Pontiac J2000 has 1 recall affecting the 1983 model year, where a brake proportioner valve can break away from the master cylinder during braking, allowing brake fluid to escape and reducing braking ability at the affected wheels.
When the valve separates, the loss of fluid means the brake circuit it serves loses hydraulic pressure, leaving the driver with reduced stopping power at a moment when full braking is needed.
