outbacknover Posted September 18, 2012 Share Posted September 18, 2012 My cruise control works but when engaged it surges and does not capture the set speed. Engaged and going down a hill it really goes crazy and can't find that happy medium. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted September 19, 2012 Share Posted September 19, 2012 Do you have a check engine light on by chance? Those cars are drive by wire and have an electronic throttle. How does the car drive/behave when just driving normally without the cruise on? Quote Link to comment Share on other sites More sharing options...
brus brother Posted September 19, 2012 Share Posted September 19, 2012 I recall there was tsb concerning cruise lunging in this year. Quote Link to comment Share on other sites More sharing options...
outbacknover Posted September 20, 2012 Author Share Posted September 20, 2012 No check engine light and no lunging without the cruise on. Brus... Any chance you have a link to the TSB? Quote Link to comment Share on other sites More sharing options...
brus brother Posted September 21, 2012 Share Posted September 21, 2012 googling around found this little tidbit: http://www.cargurus.com/Cars/Discussion-t17299_ds469549 I know there are issues with hills and 2005's cruise control. See here: http://legacygt.com/forums/showthread.php/cruise-control-surges-jerks-downhill-10725.html?t=10725 I don't have the tsb but google 2005 Subaru cruise control problem and you will find some fun reading. Ignore the threads that include issues of check engine light as their problem is unrelated to yours. Cruise stops working if there is a CEL. Not your problem.

outbacknover Posted September 22, 2012 Author Share Posted September 22, 2012 Thanks, BB. Emailing the dealer service manager. Quote Link to comment Share on other sites More sharing options...
outbacknover Posted October 10, 2012 Author Share Posted October 10, 2012 Yeah, so dealer service manager gave me the dealer, "Bring it in and we'll take a look at it." So, I'm not ready to spend the $ for a dealer opinion. Any other ideas? I did replace the rear wheel hubs and the left front hub recently, O'Reilly's says they were OEM.

wtdash Posted October 10, 2012 Share Posted October 10, 2012 I'd only suspect the replaced parts if you have a CEL, ABS or other light on. You searched/asked over on the SubaruOutback.org site? I just read thru the LGT thread offered up by Brus and it stated that some people had success w/the ECU reflash. You could fudge and state your CC is stopping when asking the dealer for a reflash, which seems to be the more common or @ least more readily fixed by the reflash. If you don't get anywhere asking specifically for this w/the local service mgr, I'd put in a call/email to SoA and 'nicely' push for getting the reflash....it may cost you $85 or if you're regular customer (maintenance or otherwise) they may split the cost w/you. I'd also be calling other dealers (gotta be more than 1 in St. Louis??). What trans? If yours is the MT, I'd replace your Neutral sensor, too, as noted. Also, have you tried to reset your ECU? Read on here/line how to do that....if you have an alarm or security code on your stereo/head unit, you'll want to get info on resetting those b4 'pulling the plug'. After the reset, see if the cruise is any better initially. GL, TD Quote Link to comment Share on other sites More sharing options...
ShawnW Posted October 10, 2012 Share Posted October 10, 2012 My moms 2006 Outback does this and it started after I replaced all of her wheel bearings. I found a sensor I had cracked and replaced that and had the reflash done. It got a little better but still haven't gotten to the bottom of it.

outbacknover Posted November 12, 2012 Author Share Posted November 12, 2012 Alright, alright... Replaced the left front hub yesterday, again. I missed my cruise control. Lo and behold replacing the O'Reilly's OEM (made in China) with a factory (made in the USA) hub solved the lunging issue. I went to O'Reilly's with hub in hand and explained and accepted it as a warranty return. I inspected the hubs prior to installing, nothing really to note. The Chinese hub does have a heavier casting, its thicker and conically shaped adjacent to the hub. The factory hub, definitely less girth and more symmetrical adjacent to the hub.
