Wife's car was doing the metallic crunch/Traction Control light thing, too. Shop diagnosed it as a loose wheel bearing. (in ours, it was causing the problem backing out of paring spots and then again when going back into drive)
Apparently, once that bearing gets sloppy, it can't/won't hold the ABS sensor ring in the right position. The sensor sends an incorrect/unexpected signal to the computer, and the computer activates the Traction Control as you're trying to drive.

I've watched YouTube videos on how to do it, and it doesn't look that difficult. But by the time I spend $100+ on the bearing, and buy the tools I'd need to do it, even if nothing went wrong during the job, I'm not entirely sure I'd be money ahead doing it myself. If we had a third vehicle to drive, I might be a little more apt to attempt it, but not in the situation we're in now.

Guess & GO!®

We’re sorry to hear you’ve been experiencing this grinding noise in your Impala, steveinvt. We certainly understand how frustrating this could be. While we see that you may have already visited the dealership to have this looked at, please know that we’d be happy to offer an additional layer of assistance if you would like it. Feel free to follow up with a private message if this is of interest.

I too have a grinding noise in the front end of my newly bought 2012 Impala. Of course it didn't make the noise at the dealer while test driving it.


I can't recreate it on demand but here's what I found. Usually happens while in a parking lot going very slow. Few times it happened while going around the block 5-15mph. Initially thought it was during a left turn but happens while going straight as well. When I come to a stop or am stopped then slowly accelerate going straight or making a left turn I sometimes hear a grinding noise in the center of the front of the car. One time it was in the left front. One time it felt like the front was dipping down. I'm a former mechanic (while back). Checked both front bearings & no play at all. Dont' see any rubbing anywhere. Maybe it's something with the ABS or TCS.


If you can't recreate it, a dealer probably won't be able to fix it unless they've had this problem before.


Stinks just getting a new/used car and has a grinding noise.

Got the grinding noise 3 times today. I had the TRS turned off from the beginning. First was backing out of the driveway then when accelerating going straight, grinding noise in the middle of the front end. Leaving Walmart parking lot. Drove length of the lot then slowed down to turn on to road. After the turn then when starting to accelerate, grinding noise. Later in another parking lot, went about 100 feet, made a left turn then when going straight got the grinding noise. Seems it happens more after making a left turn then accelerating. Wish this was a common or known problem so I could just replace a part. This sounds like it may cost a ton to fix but only after we can make it happen on demand so it can get diagnosed instead of dumping parts on it.

If it is happening with just one direction turn, look at the opposite wheel bearing. IE if it makes the noise turning right- left side wheel bearing.

Can you tell if it's a traction-control-type noise (not sure if you are familiar with traction-control and what it sounds/feels like when it kicks in)?

Personally, I think I'd start by replacing the front-right speed sensor harness. I just replaced the front-left one on my 2012 Impala because at certain sharp right turn bends (after straightening the wheels back out after the sharp bend), my traction-control would kick in repeatedly and it was had to get teh car to accelerate when it happened.

I replaced the front-left (drivers side) ABS wheel speed-sensor pigtail because this is a well-known, very common issue with these cars. The wiring breaks (or at least gets damaged) over time from all of the wheel-turning (and because of the short factory wiring).

Yu can get a set of 2 pigtails on ebay for $22 shipped. If the issue normally happens during (or after) right-hand turns, you replace the left and vice-versa.

Definitely seems to have solved the issue for me. Before I replaced it, I also tested the wiring resistance while messing with the wire and sure enough, when I bent the wire a certain way, the resistance went crazy - so the wire was definitely damaged somewhere under the wiring insulation. There are thread about this issue all over the forums.

Again, this is assuming that the noise you are hearing is, in fact, the traction-control kicking it...

RF wheel bearing perhaps.

Some things are better left unsaid, which I generally realize right after I have said them.

Great question. My last car was pre-traction control but did have ABS. So I'm not experienced with the sound of Traction Control.

I had a major change in the grinding noise situation. I was spending tons of hours researching this problem. I found a parts store harness review with 20-30 postings of the harness being bad and fixing the problem. I was about to attempt to fix it myself when the dealer offered to upgrade me to a better car, a 2014 Impala. Lower mileage, remaining drive train warranty so I took it. Could still end up with the problem in the future as it's still the 2013 body style with same harnesses. Maybe GM fixed the problem near the end of the run after all they were getting pounded with the key problem for the other cars around the same time.


I documented all this in case the problem arises with the '14 I now have.


Thanks

I have the same problem with my 2013. My son and I just replaced the wheel bearing assembly, and it didn't cure it. My mechanics can't solve my problem either. I think the only thing left to replace is the CV joint.

^^Might just be the wiring the connects to the hub. I had to replace it on mine - but it completely solved the issue. You have to cut the wiring and then splice in a new pigtail. Not hard at all - and like I mentioned earlier, the pigtails are very inexpensive (~$10).

You won't be able to see anything wrong with the wire, but the wire itself breaks underneath the insulation. In my case, it was intermittent - and when I messed with the wire (before replacing it) with a multimeter connected, I could see that the multimeter went crazy when I bent the wire in a certain spot. Common issue on these cars.

Try backing up slowly and to the right, then turn wheel all the way to the left and start forward. Mine repeats almost every time. I replaced the wheel bearing assembly and it didn't look very good, but it didn't cure the problem totally. They only thing left that rotates, is the CV joint. I can't replace this my self, and hate to spend the money and find out it didn't fix the problem. GM should recall these cars.

^^I do that every time I back out of my garage. Never had the issue when backing up though. Might be talking about different issues. The issue I'm taking about is that the traction control/stabilitrak would kick in when going around bends at times (again, because of the wheel speed sensor wiring).

I had it happen backing out of my driveway then when starting to go straight on the 2012 I had for a short time.

Did a lot of research on this and found more people have a bad cable than hub. Several mechanics that posted ratings of the cables mention their shops stock several cables it's such a common problem. The only video I found talking about the problem actually getting fixed was the cable after the guy replaced the hub and that didn't fix it. Too bad he didn't show actually replacing the cable as you don't replace the entire cable. You splice the new one into the old one. He did mention how to test the cable with an ohm meter. The wires near the plug break and when bending on a turn, the sensor goes weird.

If this happens to my 2014, I'd try the cable before the hub. Maybe they fixed the cables before the 2014's came out. Don't see many people saying the '14 have it.
