Just a heads up wire's and battery have been replaced 2 times on mine has not fixed the issue but the wires and battery did actually need replacement.

 

Wanted to follow-up here and provide a few pics. Have had a few folks contact me privately asking for pics.

Since my fix (see above post) all is well! Total cost was less than $100.00. Far cheaper than all of the dealership invoices over the years!

Here is a pic of the additional ground wire on the battery side...



Here is a pic of the new ground wire on the alternator side. The other end of this wire is connected to the alternator mount (and NOT the positive terminal on the alternator).



These upgrades were done in addition to the factory wiring. No original wiring was touched so the dealership cannot say that I caused any new problems.

Also, I used this video as a reference.. Makes this a simple upgrade...
Hope this helps!

Are you saying that the factory ground is causing there to be to much ressistance and needs a upgrade to function properly ??

 

Hi Ric,

In my case... and in many other's cases... .inadequate grounding was the cause here.

If the grounds are inadequate, the electricity will take the path of least resistance and "find ground" through other circuits. These nearly all run through the various computers and therefore will cause stress on the electronics within.

Hope this helps.

Did they told you what was wrong? What did they change?

I had the same issue and change the battery but I believe will not be enough[

QUOTE=shuvl;291321]Wanted to follow-up on my earlier post…..

A few days after my last post I received a frantic call from my wife who had again been left stranded.

Taking the advice of my father-in-law, I called a different Chevy dealership here in Atlanta. My father-in-law had been using them for years to service his work fleet with good success.

The service writer immediately gave me the GM service phone # to call for a wrecker. A wrecker was there within the hour. Two hours later I received an e-mail from the service writer confirming receipt of the vehicle.

They too were challenged in recreating the issues. So, I told them to take it for a long ride. They gave the keys to one of their mechanics and told him to hit the road. About 20 mins later the problems returned. Radio turned off and on then the dash error lights started flashing.

A few days later we were called to come pick up the Captiva. They had replaced the Body Control Unit (BCM). All was good…. Well sort of…

Within days the problems returned. So, back to the dealership we went. Only this time it would be different....

The service writer/dealership offered us a loaner to drive.

A service ticket was opened up with the GM engineering team.

With the help of GM engineering, the service techs were able to diagnose the problem as being low voltage in both positive and negative battery cables. The complete assembly was replaced.

Once the new cables were installed the service writer asked if they could drive it over the weekend to monitor it further. Absolutely, we said.

The following Monday we were asked if they could keep the car for a few more days. A GM district manager was coming in to see the car and to review the case. Absolutely x 2, we said.

When all was said and done….

It’s been over two month’s since we picked up my wife’s Captiva. It has since been running like a top. Not one “Bleep” or flashing error dash light. We even took the car on a 1500 mile trip over the Thanksgiving holiday and experienced no issues.

Our experience with this new (to us) dealership was nothing less than fabulous. Our service writers, Danon and Vladimir were top notch! They understood our frustration. Their communication of the issues and their plan to resolve them were spot on.

When / if my Chevy Tahoe does finally decide to give it up (300k+ miles and counting), I will be coming back to these guys for my next new Tahoe.

Hope all of this helps others…[/QUOTE]

 

I had the same things done to ours wasn't so easy for me to get our swalrdealeto do it but anyway, when they replaced the back and wire harness to battery it did solve the issue for a few months we thought we had finally got it fixed as this suv has been a nightmare. Unfortunately it did return back to square one. How ever I did up grade engine to chassis ground, alternator ground, batttey ground, and alternator to chassis ground. I got the idea from shuvl and took it even further. So far it's working fine only been a couple days tho I will keep everyone posted if it is a true fix. Best luck to anyone who has a junk captiva.

 

 

Give the grounding issue a shot. That shuvl posted I gave done this as well so far so good no hurt in trying thus is by far the cheapest way to try to fix this. I went over board an used a piece of 99.9percent ofc copper wire heat shrinked it after soderin terminal on each end an used a cable cover over that. Make Shure it's secured to battery well but most importantly make sure the other end of u're wire has a really really good grounding point and has bare metal I ran mine directly to the frame and wire wheeled it clean attached it with a brass nut and bold bolt and sprayed clear coat over it so there would be no issue of rust or corrosion. Good luck let us know of those works for you as well!

 

 

This was early on in the process. Please see my updates that came later. For this issues... I used my CarMax warranty to pay for the fix (bcm replacement etc.)

Responses from others also show Chevy is not footing the bill for any of these fixes. Footing the bill would insinuate that there is a problem in the first place. That's why I tracked down the guy that provided the resolution for my problem.

Hope this helps.
