Hope they'll figure it out and warranty it if its not related to things you done to it. Did you pull out your tune?

The only visible mod on the car right now is the headers. The dealership can't read the tune. They can however see if it has been tuned and how many times. Returning the tune to stock wouldn't have done anything. It would have just added another marker to the CVN.

The electrical issue had nothing to do with any of the mods so they will have to fix that. Not sure if they could void the rear either. I guess they could try to deny the converter but it is a known problem. Just like the rear. We will see.

Very curious about this one fingers crossed for you keep us posted!

Thanks. I am thinking it is an online fuse somewhere I couldn't find. Or the BCM took a crap.

I vote BCM took a crap because of the radio.

I have no back up camera, radio stays on, no dash gages, no DIC info, mode selector doesn't work, no TC control, and one or two other things. But the car drives fine.

Dealer didn't get back to you by end of day?

You know I'm with you on this, I'm keeping my fingers crossed. I asked my service manager about the converter since mine has had some vibration and if they only had to read the tranny tune I wouldn't have an issue or the rear since mine has already been flushed early on since it was having issues. If they did ask them to pull the engine tune they could void the converter and drive train warranty also.

So it looks like the combination of direct injection, Low timing and cramped engine bay space will be causing multiple header cars to have this problem.

The passenger side Header runs dangerously close to a wiring harness that runs parallel to the frame rail. The excessive heat generated by these headers can cause this harness to melt. We sell and recommend installing a barrier wall between the harness and the header. We also sell a fire sleeve and fire blanket that can be installed to the wiring harness prior to final install of the header on this side. Driver side is fine except for the plastic cover on the steering shaft.

The harness in question is one that sends multiple signals from the ecm to the body control module as well as the ac system,and many more things inside your car.

The repair of these melted wires are not covered by your GM Powertrain warranty as the cause was not GM fault.

In my opinion the Header Manufacturer is at fault for not doing proper testing and data collection with both thermal test as well as video of how much heat is present in these areas prior to headers and with headers.

So be prepared to have a bill of $1300-$1800 come time to pick up your car, the dealers love fixing other peoples mistakes.

On a side note I could be completely wrong, it may just be a programming upgrade as there seems to be a lot of dash going blank issues with these cars.

Good Luck.

HUH, that is interesting. But you may be right since he just installed the headers and the first pass with them the dash took a shit. Pray, good luck.

If this is the case coated headers should help prevent this. I got my kooks coated. May still want a barrier for extra insurance if this is in fact the problem

Not a peep. So either they are fixing it or formulating a plan to hit me with today. They did have to trans line recall deal and another recall to do on the car so I am sure those took some time as well.

I paid out of my own pocket at 1,500 miles to have to trans and rear flushed since I was starting to have some issues. I hadn't read it was a problem yet and figured an ounce of prevention was worth a pound of cure. I told the service guy about the three flush deal that GM will recommend and he said that in his mind they had already done that and the problem came back. So why would they do it again and not just replace the parts. We will see. I am not sure how they could tie an ECM tune to a known issue in hundreds of bone stock cars. But I am sure if GM can wiggle out of warrantee work they will. I will find out today.

Very good information and I am glad you guys offer a solution. Where were you a week ago. LOL. I did see the harness you are speaking of but it appeared to have plenty of room. It also already has heat shield around it. Are the wires melting inside of the loom? I rechecked everything under the car and around the headers and did not find anything burned or melted. But if it is happening internally then that could be the case. The one wire that does concern me is the knock sensor wire on the drivers side. The heat shield for that one does just about rest on the header tube. I only had the headers on for a day and a half and about 200 miles but to much heat can cause things to go bad fast. That would be one of the fastest fails in history. But the timing does coincide. I am wondering if AFM mode compounds the issue. Even less timing and no fuel for extended periods of time.

I guess I will do a search on the dash going out unless you were being facetious with your last comment. It seems to be a new one on this forum.

As far as the bill goes, I only signed for them to look at the issues I described. I obligated myself to pay a $85 diagnostic fee. They have that no hidden fees guarantee. I am sure there is a bunch of fine print in there but if they went ahead and did a bunch of repairs without price authorization from me like all the other times then we are going to have some issues. I am not sure if there is a legal leg I have to stand on but that is GM's policy, not mine. Like stated above. They may be researching the issues and fixes and waiting to hear back from GM before they hit me with a price. That is fully acceptable in my book. You play, you pay. I understand that and won't say a thing about it.

I will hit you guys up later today about your heat protection parts.
