I am having this traction control problem with my '09. Starting from stopped the traction control kicks in and the light comes on. I have been disabling it for the last couple weeks and have have no problems starting from stopped. Please post what was done that fixes the problem since I have no warranty and want to know what I am going to be looking at for price.
 
It sounds like my 13 imp is also doing a "scraping noise" ..........I realize that the strut works with the wheel, so that it can't be a clearance problem......

But i did find that the rubber/plastic cover in the lower strut dish had plastic rivets with long plastic keepers on the underside of the dish, that could have come in contact with a tire when turned sharply.........i cut them off thinking that i had the problem solved...........

that did solve the one scraping noise, that i heard when the car was coming off the sidewalk with strut up position and wheel turned fully either way........


but now i have been noticing this noise when making a right turn 'like a 90 degree corner', at slow speed, from stop......i will check the wiring problem mentioned above, and try to remember to shut down the trac control for a few days........

It sounds to me like we are all experiencing the same problem........what worries me is whether or not it could turn into a safety issue :dunno:
 
sooooo i thought there was a GM rep. here every now and again:dunno:

.......this sounds like a problem that is pretty worrisome to a lot of people here......
 
ABS issue - may be a simple fix!

For 3 years I got intermittent TRACTION / ABS warning light errors which would come sporadically. I had both front hubs replaced at a cost of over $750 and they would just keep coming back. Seemed like whenever I backed out of the driveway or turned a sharp corner or hit bumps... one shop told me it was the ABS controller and that would cost $1400 alone just for the part. I finally checked You Tube and forums and dissected a wiring harness of a wrecked Impala and concluded it MUST be a connection. There is a TSB out there for wiring harnesses to rub against the AC dryer unit and eventually short out but mine wasn't doing that. It got so bad that the ABS motor would sporadically come on even when driving down the road. The ABS computer threw 3 codes at me - C1225, C1226 (ABS sensors both sides) and C1216(ECBM issue). And it happened on every bump. So I knew it must be wiring. I finally got my daughter to sit at the wheel with the car running, and I started wiggling wiring and connections. You know what it turned out to be??? A simple connection! The connector where the ABS wheel sensor plugs into the main wiring harness for the car! I pulled it apart and it was corroded green inside. Salt must have gotten in and corroded the terminal. I also noticed that the harness had little slack and when you cranked the wheel all the one way, it almost pulled apart. So I hit the connections with penetrating oil and rust preventor oil (Krown) and pulled some slack from the main wiring so the wheel could turn but not pull apart the connector. No more problems. A simple rusty connection was causing the computer to throw 3 codes, and cause all this annoyance! It makes sense you know - cause they would replace a whole hub, and 3-6 months later it was acting up again. Why? Because when they disconnected the old one and plugged the new one in, it took that long to get corroded again. So its a bad connector design. I took some silicone and sealed the holes on the top end of the connector harness, so as to prevent salt water from draining in again. I would check the front two connectors and see if they are simply white/green corroded and go from there.
 
As for the guys earlier in this post talking about intermittent slipping upon startups , I don't know but it sounds like a transmission PCS solenoid issue - had this on both my 2004 and 2010 Impalas. Started on both around 150,000 km. it happens intermittently at first but slowly gets more often. Both have a 4T65E transmission. You step on the gas and it hesitates for a second then lurches forward. If this is what yours does, let me know.
 
I just started to get that scraping rubbing noise on my 08 SS. When turning to the left gently under acceleration like leaving the front of the house or pulling up into the driveway,
that could be one of your splash guards for the engine came loose, when the tire turns right or left it contacts the splash guard that has popped out.
 
Just got my 2013 LT back from the shop. I had the ABS/traction control going off from a stop when turning left, like a couple others had mentioned. The dealer found that there was water intrusion into the RF speed sensor harness. They replaced the harness. I haven't tried to make it act up again but it did it often enough that I should know it that was the problem.
 
I usually just turn off traction control, to prevent it from coming on if the tire slips.

I have the same problem with a 2013 LTZ. When I turn the traction control off, it does not happen. Only with TC on does it occur. I agree that it is a safety hazzard when you are trying to accelerate to make a left turn across traffic. It sounds just like the ABS does when you are braking on slippery surface and it cuts the breaking to allow the wheel not to lock-up. This has to be a common malfunction if so many are experiencing the exact same thing.

Has anyone found anything that will fix it?
 
A set of new tires helped me with this problem..........but it is still there.....I may be wrong, but it seems that the weather has some effect, during the winter the problem seems more prevalent than in the warmer months.......that tells me that a wire or connection could be contracting enough to move enough to break connection or short thru somewhere.....

My imp is in the garage most of the winter, so i can't be 100% sure about this theory...??....I will be checking it out more closely when it quits snowing.......

This issue seems hit or miss. For example, with my 2012, the way that my garage is setup, I turn the wheels "lock to lock" multiple times when entering/exiting my garage - and I've never had an issue with the wiring harnesses on mine - but others have the issue even though they don't turn the wheels all of the way back and forth as often.

I think it all has to do with exactly how the wiring was installed at the factory - some cars have the wiring so tight that it causes issues and some don't.

At least that is my theory! :)

Is your garage heated??........Only asking to investigate another angle to my theory.....my garage is not heated and detached......I have a blazer to do all the dirty work......i use the imp so rarely that i wonder if i should put a bat tender on it.......so it's hard to diagnose .......when it sits ;-)

I really would also like to figure this one out.........GM sure hasn't helped anybody with the problem.........

No, my garage is not heated, but it is attached - so it doesn't get quite as cold as outside temps.

My understanding is that the issue is a known problem with the way they "secure" the wires running to the hubs. If secured too tightly, it pinches the wire (and eventually breaks it) when turning the wheel all of the way. Once the wire breaks, the Traction Control message is displayed on the DIC sometimes when turning the wheels (sometimes the broken wires make contact and sometimes they don't). Again, that's my understanding of the problem. As to why if affects some and not others, I'm thinking that it might be related to how tightly the wiring is "secured" - some being tighter than others?

That and wire length may play a part. Let's say the length at lock is 5 inches, well someone had the bright idea to make the wire length 5 inches +/- .1 inch. So you could be getting wires that are a tad short (4.90 inch) to begin with or you could be getting wires that are up to 5.1 inch. Not much I know, but maybe enough to cause an issue. Then like JT said and well now you have a major issue on your hands.


This was a guess on the tolerance, because I don't know exactly what it is. 1/8 inch is .125 for those of us that don't like math.
 
Wife nearly got cut in half this morning making a left turn into her work. This traction control issue should have Chevy shaking in their boots. If 1 of my family members gets hurt with this common problem that Chevy has not recalled and fixed, I will spend my last penny to inform the public of their lack of action. This is definitely a recall situation.Their waiting till people get killed to act. Its no wonder people are fed up with Chevy. It will definitely be my last Chevy.
