One problem related to cruise control has been reported for the 2003 Subaru Impreza Wrx. The most recently reported issues are listed below.
The cruise control unit on my car will cause the throttle to remain open, even if the cruise is turned off. This can result in anything from higher than normal idle to random instances of wide open, uncontrolled acceleration. The car has been to 2 different Subaru dealers for a total of 7 times over the course of 5 years, and the problem has yet to be resolved. All applicable TSB's and recalls have been performed, but problem still occurs.
