Speed control / throttle Vehicle recall #03V133000 · 2003 · 3,291 vehicles
What's wrong: On certain sport utility vehicles, the throttle can stick intermittently during its operation. The exact point of sticking is not predictable and can result in a higher engine speed than expected.
Why it matters: In the case where a throttle fails to return to idle, particularly after a high degree of engine throttle application, the driver will experience difficulty in bringing the vehicle to rest, increasing the risk of a crash.
The fix: Dealers will replace the throttle body.
