Two problems related to cruise control have been reported for the 1999 Subaru Outback. The most recently reported issues are listed below.
While driving on highway traveling at 70mph with cruise control on, had to apply brakes because of a slow moving vehicle in front. Vehicle locked and the rpms shot up high, and shifted into a lower gear. Shut off the cruise control at this time, and it was still locked into that mode.
Whenever brakes are applied there is sudden acceleration. (cruise control was not used). Dealer was not notified.
