Got5onIt Posted January 4, 2012 Report Share Posted January 4, 2012 The speedo TSB on 2010's should've all been updated in 2012's I would think. Anyway, today while driving on the freeway my speedo all of a sudden started reading ~25mph less than it should have. I was doing 65-70mph at the time. Just like the 2010 TSB 10-18-7 stated, I had to turn the car off in order to reset it. The speedometer began reading correctly. Anyone with a car built after 3/25/10 have this issue? I'm hoping this is just an isolated incident. 1800 miles on the clock with 2 minor hiccups so far... Link to comment Share on other sites More sharing options...
EcoBrick Bob Posted January 4, 2012 Report Share Posted January 4, 2012 Assume this is a Swiffer Motor issue... or a ground problem. Link to comment Share on other sites More sharing options...

EcoBrick Bob Posted January 4, 2012 Report Share Posted January 4, 2012 A Swiffer motor is the electric device(s) that turns all of the gauges. GM had a big issue with these in their Large Pickups and SUV's. My Denali did this off and on... and finally about the time I was going to get them fixed... GM came thru with a recall (2008). Believe they work off of voltage increases/drops. As for the ground issue... My 2004 GTO had erratic gauges and speedometer. Turned out to be a wire that was grounding out intermittently where it passed thru the firewall. Link to comment Share on other sites More sharing options...
Got5onIt Posted January 4, 2012 Author Report Share Posted January 4, 2012 Thanks for the info, but are you sure you don't mean Stepper Motor? I hope it's not an intermittent grounding issue. I've yet to see any other issues on my cluster, but I've only put 1800 miles on it. I'll just have to cross my fingers... At first I thought you meant to type Stepper Motor and the notorious spell correction came up and auto-corrected in your phone or something. :RpS_w00t: Link to comment Share on other sites More sharing options...
PDXSHO Posted July 25, 2012 Report Share Posted July 25, 2012 [ATTACH=CONFIG]879[/ATTACH] This explains why my car said I was doing 95 in a 35 zone with traffic last night. Hmmmmmm Link to comment Share on other sites More sharing options...
bpd1151 Posted July 25, 2012 Report Share Posted July 25, 2012 Well? Even though it may be a posted 35mph zone, were you travelling at 95?? Hahaha. Sent from my DROID3 using Tapatalk 2 Link to comment Share on other sites More sharing options...

mjhpadi Posted July 26, 2012 Report Share Posted July 26, 2012 More often than I'd care to count.... Like trying to count the times I've heard: "I'm only here because my someone ratted me out!" And the always good: "I didn't do anything wrong!" Link to comment Share on other sites More sharing options...
vernonator Posted July 26, 2012 Report Share Posted July 26, 2012 I have seen this exactly once in my 2012 - guage read exactly double what I was really doing. Turned it off and then restarted and have never seen it since. That was when it was less than a month old so 8-9 mos ago. Link to comment Share on other sites More sharing options...
