The 1998 GMC Jimmy has two recalls, both serious: a rear brake line that can crack and slowly leak fluid until the pedal goes soft, and a front lower control arm that can separate from the frame.
On the brake side, a fatigue fracture in the right rear brake pipe allows fluid to seep out gradually, reducing braking force at the moment full stopping power is needed. On the suspension side, this recall affects 4-wheel drive and all-wheel-drive models: one or both mounting nuts on the right front lower control arm may not be tightened to the correct torque, allowing the bolt to loosen and eventually break. If the control arm separates from the frame, steering and handling control can be lost.

What can fail
The attaching nuts on the right-hand lower control arm may not be tightened enough, allowing the bolt to loosen and break. This could cause the lower control arm to separate from the frame.
What the fix does
Dealers will inspect the right-hand lower control arm nuts and retighten them to the correct specification.

At a glance
What can fail
The rear axle right-hand brake pipe can develop a fatigue fracture, causing brake fluid to leak slowly. If the pipe breaks completely, the brake pedal drops and rear brakes lose effectiveness.
What the fix does
Dealers will inspect the brake pipe and replace it.
