The 2000 Pontiac Bonneville has two recalls, the more serious involving a fuel pressure regulator on 3800 V6 engines that can leak fuel into the intake manifold, causing a backfire that ruptures the manifold, displaces a fuel line, and can result in an engine fire.
The second recall involves an internal fluid leak inside the brake hydraulic control unit. When the anti-lock brakes, traction control, or stability control activates, the system may not function as intended, reducing the vehicle's ability to manage braking in demanding situations.
At a glance
What can fail
The fuel pressure regulator leaks fuel at a higher than normal rate. Leaked fuel can enter the intake manifold through a vacuum line, potentially causing engine backfires during starting.
What the fix does
Dealers will replace the fuel pressure regulator with a new one that has an improved diaphragm to prevent leaks.
