05 Z51 MN6. 14 mos old. 5300 miles. Dead for the first time! I crawled thru the hatch, opened the hood, and checked the battery voltage. 2.4volts! Yes.......2.4! Battery is charging and I'll see if it starts tomorrow. The dealer was warned and I've printed some threads from the archives where GM admits it has a problem and a team has been assigned to look for the cause. That should eliminate the "gee we've never heard of that before" response. It looks like there is a Priority Start in my future.

I have a couple of questions:

1. When you pull the door release in the hatch area, how do you get the door opened AND closed since the window won't index without power?

2. When the Priority Start kicks in, how do you get in the car to reset it?

3. When you reset it, is it necessary to re-program all of your radio settings, personal preferences in the DIC and so forth?

For the record, yes it was in reverse, parking brake on and was not driven for 4 days, which is nowhere near as long as it has sat in the past without driving. Was stored this winter with a Battery Tender and fired right up 6 weeks ago and every time since then. 14 mos without a problem and today BAM........DBS!

To those who have had the problem, I sympathize. To those who have not, just because you never have does not mean you never will. For your sake I hope your ride runs perfect and lasts longer than you do.

Good luck.

P. S. I #@*$ing love this car and there is no substitute!!!!!!!!!!!!!

 

Don't close the doors with the windows indexed up. You'll have to lower them and re-index them after you recharge the battery.
You can reset the prioritystart module by pressing in the cigarette lighter.
As I recall, most personal settings stayed put with my DBS episodes. It's been over a year without DBS and my mind's slipping! I never did get the prioritystart module, but I think the memory settings are retained after a reset.

 

Had my Vette six months and had let it sit during the winter for up to two and a half weeks with no problem. The in March 2006 after car was not driven for three day DBS hit. I charged my battery and it reach a level that let me start the car in about 10 minutes with a 10 amp charge. I got a priority start and it has been great. I have had to manually enter the car two times since I put on the priority start.

To answer your questions:

1. When you pull the manual lever in the hatch area, the door will pop open. You can then get in the car, but the window will not index so if they are up, you cannot close the door.

2. To restart the car, merely push in the cigar lighter and the car will power up. In a few seconds, you will be able to start the car.

3. All you settings will be retained. They are not lost. Your windows will have to be re-indexed, but I found the two times priority start kicked in, my windows re-indexed when the car was started.

I hate this situation because the life of your battery is reduced after it goes dead. The priority start has been a life saver and I hope that GM figures this out, but I am not holding my breath.

Good luck to you.

 

 

Like they said above but you can close the doors if you do it slowly and carefully, hasn't been a problem for me after activating the Priority Start.

 

After my DBS, the only way I could close the door was to remove the top. I now have a Priority Start installed, but it's never been tripped since my 11/2005 battery drain. I had 13 months of perfect starts in all kinds of sub zero weather...no problems..until it finally caught up with me. No trouble since then.

 

Thanks for the response. To clarify, when I pulled the door release in the hatch area, the door released but the window was still up into the
door seal. I tugged on it lightly and it would not open. Do you have to put some muscle into it and give it a strong yank?

 

You'd kinda figure that GM would come up with a priority start devise and install them on all Vettes, until they can figure out the problem. You'd think that 60K for a car it should start anytime you try it....... JMHO

 

When mine died I left the door cracked open while the battery recharged, a good pull or a good slam my break the window.....

 

I only paid $50K for mine...maybe that's why I had DBS. Maybe DBS is related to the price we paid for our cars...hmmmmm.

 

I have PS on my C6. Door pops open with the battery dead when you pull the cable in the trunk. I can also close it quite easily, despite the windows not indexing, with the battery "dead". Window did not break the 4 or 5 times I did it -- not that I'd suggest pushing your luck.

All the personalized settings are retained.
The only things you have to reset after you start the car with Priority Start are

• reset your clock
• re-index the windows

that's it - no other hassles.
I really love Priority start. I left the car in neutral (MN6) and / or left headlights on about 12 times after I got the module -- just to test the gadget out . it's great to have.

 

The same thing happened to me after my first DBS episode; I couldn't open the door because the window was up into the seal, or so I thought. Installed PriorityStart and got into the habit of lowering the window an inch or so when I parked in the garage. Sure enough it happened again - car is dead, but this time PriorityStart save me from DBS. Pull the door release; go to open the door, wtf, the door won't open just like the first time. Now I know it's not the window stuck into the seal because the window is down an inch. I reach into the hatch while standing by the door, pull and hold the release with the right hand, open the door with left hand. No more problem.

PriorityStart works well. I haven't lost my memory settings, but you do have to re-index the windows and the tire pressure readings on the DIC may show 0 until you drive it for a bit. Pita though, if you have the hood open for a while the underhood light causes enough drain on the battery to trigger the PriorityStart.

 

I feel for you, maybe GM will fix this issue one of these days. In 13 months I have not had DBS but I am sure my day is coming. At that time I will install PS. Good luck at the dealer. Let us know the outcome.

 

Once you have the charger hooked up you can lower the windows slightly and then you'll be able to close the door while the battery finishes charging up.

 

Thanks again to all for the responses. I'll probably take the car to the dealer next week, but I expect little from them because they look for a TSB and since nobody has found the fix, there won't be one. I suspect that with all of the wireless devices in use today, something is causing the car to wake up and cause the drain. Does anyone have a theory on why the battery saver feature that would shut off lights that are left on does not sense the same DBS drain and power down the car? That would make too much sense!
With all of the cars that are now on the market with keyless start, I wonder if any other makes have encountered the same problems, and discovered a fix that might translate to finding a fix for the C6. To all affected, keep pressure on GM to find the fix. I't ain't over until we win!!!!!!!!!!!!

 

If you shut down the car without meeting the reverse requirement, the 10 minute timer obviously does not kick in and turn things off. That's for sure!
My theory of a defective reverse sensor causing DBS explains the similarity of DBS and owner error. With DBS you are unintentionally shutting down without meeting the reverse requirement. So the timer doesn't work.

My theory post #6, probably needs revision:

Where is the best place to buy a priority start and which one of the two is best?
