Great post ! Mine also was just starting to rub. Taking it in this morning to have them take care of it and at least have it on record. My thought is this will become a huge recall. Thanks again.

The second pic, the pink drawing shows how this route helps to pull the cabling back towards the motor.

Very good catch. I think your assessment is spot on. Mine looks more like pic #1. I think to correct this, just unplug the connector with the red/gray wires, route it as shown in pic #2, and plug it back in.

Thanks again to the OP. Dealership addressed my concerns and obviously agreed. They inspected the wires under the protective sheathing and found no damage what so ever. Zip tied the wire loom back and out of the way. All good

I am glad I could help thanks for providing additional pictures and information on the topic. I will keep you guys updated when/if I hear back from the GM.

I looked at my wiring harness last night, no weird bending, looks good-to-go. Nov '16 build.

I though back to reading this thread from yesterday and how my car acted after it happened..told him to go look at the harness, what do you know... FRAYED WIRES. He has a 17 1LE as well.

This must be a build problem during that month. Not sure of the scope yet. Maybe ask a mod to add a poll for this.

ETA: he already commented on this thread nevermind

wow, yours also had such low mileage. In my case it started happening at around 2k miles. The new 1LE in the showroom had only 9 miles on it !!

Went to look at mine, you do not need to remove the intake to inspect it just look infront of it.

My car was build 3/17 and looks like there is extra tape around these wires already.

You may still wanna put a zip tie around it and pull it back a tad bit more...just to be safe.

I agree. Unless the angle/perspective makes me think that way, it seems a bit close to A/C belt to my eyes also

I zip tied the section that loops around to the main harness (toward the closed end of the loop). There's much more clearance now, but I will keep an eye on it to make sure there continues to be adequate clearance with this initial solution.

Thanks again! You saved some of us a potential trip to the dealer.

This is really a crappy routing design for the harness for it to potentially be that close to the belt. GM should fix this ASAP before they end up with a ton of warranty claims and unhappy customers!!

The zip tie gave me ~1" of minimum clearance after everything settled (checked a week later). I still didn't like that. I ended up removing the zip tie and routing it the same a pic2 in this post and now have a few inches of clearance:

I unplugged the the connector with the gray/red wires and routed it behind the other portion of harness and plugged it back in. That has to be the way it was designed to be from the beginning. It didn't feel like there was any excessive tension anywhere that I could tell after rerouting it.

Big thanks to glamcem, DenverTaco07, and everyone else that helped figure this one out!!!

Thanks for the post. I am a fortunate one. Plenty of clearance at 22k miles so far. Never hurts to check though.

I ran into the same issue after my second track day. I initially thought that I had bad fuel and since I couldn't reset my ECM (apparently not easy task on these cars), I was under the impression that the ECM cannot recover itself from the bad/low octane map or pulling timing or something (as it did with previous Gen Camaros).

I've scheduled an appointment with my dealer for this Wednesday to do that. It's also a bit hard to replicate the issue on rainy, cold days since it requires a WOT and can only be done (safely) in traffic on 2nd gear.

I was scratching my head because it happened to a 17 Camaro SS owner, a brand new 1LE at the dealer showroom(!), to my 17 1LE and a 17 ZL1 owner. I would understand the SS cars but ZL1 has a completely different motor and a tune of course. Forum member "geaux_tigerss" says that the dealer replaced the camshaft solenoid and ECM but still didn't fix the issue . It turns out that the A/C belt -under high load- was rubbing against the wiring harness right below it, and stripping two wires and causing that surging issue at around 5500 RPM. It didn't reach to a point where it displays a CEL in my experience but he had both CEL and the issue was existent all the time.

I checked mine and as expected I was dealing with the same exact issue. I took some pictures showing how it's stripped. It looks like a manufacturing defect and somehow they didn't pay attention to that clearance between the wiring harness and the A/C belt. I would be surprised if the clearance is different on other cars unless they changed the method of putting the wiring harnesses all together. I would highly advise to check yours and if you don't see any rubbing/stripped wire, consider yourself lucky and simply put a zip tie to make some space between those two (wires and A/C belt above it)

I put the below pieces aside for an easy access:


Notice the two completely stripped wires touching each other in the below picture.. right next to the purple wire:



I used some electrical tape to insulate those two wires (simply pushed some tape with a thin, flathead in between) then wrap around it with another electrical tape and zip tied it with the connector wire so that it would pust it away from the belt and give some space.
Note: Needle nose pliers helps a lot if you have big hands like me

I took it for a quick ride to test it and the hesitation is gone now. Phew! what I relieve ..

What is your build date? My 12/16 build doesn't have any electrical harnesses or wiring near where this could happen. By the way, your flywheel/harmonic balancer (whatever GM calls it) looks great. My has rust spots already being here in Florida.

It is 11/16

Thanks for posting this. Just checked mine, 11/16 date, and appears to have a few inches of clearance, although I only have about 600 miles. Hope it stays that way.
