JonLGT Posted September 22, 2008 Share Posted September 22, 2008 I have had this Issue since I have owned the car, although its not really a big deal I was wondering if anyone else was experiencing this. Most of the time when I am around 50-60 in 5th gear with the cruise control engaged, every once in a while (not even every time I drive the car) the car will hesitate for a second and then keep going. It isn't a very rough hesitation, but you can feel it, almost like tapping the brakes. Link to comment Share on other sites More sharing options...
GTkansan Posted September 22, 2008 Share Posted September 22, 2008 I have something similar when i use the cruise control accelerate switch. It start forward well, then almost stops for a second, then goes HARD. Its very weird Link to comment Share on other sites More sharing options...
SilverSeraphim Posted September 23, 2008 Share Posted September 23, 2008 Jon, maybe the road has a slight down grade and the cruise is cutting just a second to maintain correct speed? I notice that when i reach the bottom of a hill and start the next upward slope I can feel the cruise "kick in" again. Not violently or anything but it is noticeable when it starts to open the throttle to maintain speed. Kansan I've only noticed that hard jump if I bump the control lever up a couple times and then hold it up. I think it gets confused between increasing by ~1mph several times and then going straight acceleration. Link to comment Share on other sites More sharing options...
CMull123 Posted September 24, 2008 Share Posted September 24, 2008 I get this same feeling, never had it in cruise though, only in 5th when I'm just cruisin along. I never thought much of it other than a change in the road grade and the throttle was compensating. But I have noticed it and wondered why the hell it does it.

GTkansan Posted September 24, 2008 Share Posted September 24, 2008 Mine is manual, in 5th, it does it no matter what the grade is. It goes immediately upon holding the cruise switch, then bogs down a second later, then comes on with a fury. Link to comment Share on other sites More sharing options...
SBT Posted September 24, 2008 Share Posted September 24, 2008 Mine is manual, in 5th, it does it no matter what the grade is. It goes immediately upon holding the cruise switch, then bogs down a second later, then comes on with a fury. The gas "pedal" is electronic and the cruise control "lever/switch" is too, so it's more a function of the electronic throttle interface with the cruise control IMO on a turbo motor. The bogging is likely just the typical Subaru throttle response (turbo lag) to WOT, which is what you're doing when you hold the hold the cruise switch in the accelerate position. The stumble while in cruise, not sure how to troubleshoot that. It could be any number of variables, i.e., gasoline, low oil (which affects valve timing), intermittent ignition coil issue, fouled injector, etc. But if it does it consistently, seems like something that should should up with a Subaru Select Monitor check or even with a dealer tech drive. - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...
Opie Posted September 24, 2008 Share Posted September 24, 2008 I'll bet it's a touchy nuetral safety switch...common problem that sometimes causes a CEL. Link to comment Share on other sites More sharing options...
