More times than not, my C6 will not turn over when I first push the start button.

I just let it up and push it a second time and it always starts right up.

I just thought this was normal since it has happened since new and it is consistent in the manner in which it reacts.

I had my crank pulley fixed. I'm still waiting to figure out why my car goes into pseudo-neutral in a hard turn. You guys have electrical problems. Are we supposed to just accept the fact that these things are normal???? This is my first American car since my 1992 vette. Every car in between was flawless and now my C6 has plenty to gripe about as did the '92.

What gives??? American quality?

 

Well the sage continues with yet more "Service Column Lock" errors. I took to another dealer who, like the first, tried to say its' a FOB issue, but after some assertive pushing, they threw the computer on it and found over 14 codes posted. They checked all the wiring, but nothing jumped out at them, so now they are going to call Bowling Green for help in the morning-wish me and Black Beauty luck

 

This is a follow up to my earlier post. Today this happened 2 times. Clutch in all way, in reverse, push button...nothing. Let up on it and push again...nothing. Let up again...take-off.

Go figure.

 

Happened to me today, too. I just got the car Saturday!!!!!!!!!!!!!!!!
The engine light came on, too. I just stopped everything and waited a bit and it started. For the price, I want that baby to start.

 

Happens to me sometimes. I can put my foot on the brake and it will crank or I can take it out of reverse and put it back in and it will start. Happens maybe once ever two weeks. Cannot seem to find the reason. I follow the same procedure when turning off car every time. Oh well at least it starts.

 

Saga Day 3,

All the codes that were thrown were software based, and Bowling Green had a hell of a time clearing the codes. To non-Techies, software codes differ in that they are a response to inputs (normally values out of ranges expected by the software or inputs the software never received,) rather then a failure of an end part such as a water pump or MAF. Right now the dealership and BG are trying to force the car to reproduce the fault condition, but I suspect that is a loser idea since it is likely the error occurs long before the code is thrown and they won't know any more then than now even if they throw a code.

In any case, Black Beauty comes home Friday afternoon fixed or not.

 

 

Saga Day 4-not much happening at the dealership or with Bowling Green's crack team of electrical weenies. They were just starting to run some test on the BCM voltages both in and out, but the dealership person really didn't know much more. In any case, I think they are in the right area now, but I would also stress test all the relays, the personal/retained memory management system, and the security system. Most of my bugs seem to come right after I lock the steering wheel getting out of the car.

 

Saga Day 4 Continued

Dealership called saying that Flint and Bowling Green are saying that the condition is probability 99% sure from a bad reverse solenoid. Does anyone have an idea where the thing is located as I can imagine 2 different places, and my hope is that they don't have to crack the case to get to it-am I lucky or what????

 

Sage Day 4 Final

Well Black Beauty is back at home now. With 3 engineers, one in California, one in Michigan, and one in Kentucky, and after the one in Michigan with a Z51 6sp on the rack applying the test findings on that mule, they decided that the 2nd Reverse Solenoid switch was not closing all the time (thereby not shutting down the computer/electric systems properly) was the cause. The fix, they feel, is to switch was to change the wiring of switch 2 to switch position 1. The old switch one tells the PCM its' in reverse while old switch 2 told the BCM it was in reverse and to shut the system down. The switches are engaged with a paw/lever and the engineers feel the paw would sometimes fail to fully reach or close old switch 2 thus the system would never shut down or worse, crash the BCM. The two switches are the same so it was a matter of moving wires. While the shop supervisor and I are rather doubtful, we both have to admit the first few codes thrown are coming from the transmission. The only change I will see that if #2 is not closed the DIC will report that I need to place it reverse. In any case I have agreed to share my findings of whether the fixed worked or not to the engineers. Since I make my money in programming and technical support, this request by them doesn't faze me as I rather be part of the solution then just suffering the problem.

The other reason I have gone in to such detail here is that I notice others reporting their problems in the forums, but never really bothering to post what their solution was-assuming a fix was ever found.

 

Details are good. Hate guessing endings.

 

Sage Day 5

Well the fix did not work, if fact it was so bad that I had to disconnect the negative battery cable to reset the system so that it would start. I was not in an area I wanted to be hanging around for a tow truck as the sun set. Main same error "Service Column Lock"-normally I can get the car to start by opening the doors etc etc

 

So, how did it end up ? Did the engineers find the root cause or are they still just takeing stuff apart and spouting wags?

 

Anyone else with starting problems or electrical Gremlins? TTT

 

I had the same problem the other day."Service Column Lock". Would not start. Tried several times, after about 15 minutes of intering and exiting the car it finally started. Electronics are nice, but can also be a nightmare.

 

Well just talked with the main service rep who actually is working on the car himself, BG and Flint feel there is either a damaged wire in the dash or its' the BCM. Apparently the dash & center console is apart and they are tracing the wiring to see if there is a loose connection or a pierced wire. It's not likely tho that Black Beauty is coming home for the weekend unless they find something to fix. He also stated I had more codes showing pointing all over the place-brake pedal position, my LED 3rd brake light, my door locks etc etc . Who Knows! We are both getting tired of the problem. No end in sight!

 

Wow.....what a mess! Keep us posted on the outcome.......i think it's close to 'buy back" time!

 

Saga Day 15

The Service Rep called today, stating one or more Bowling Green Electrical Engineer(s) are coming down to look at the car since the wire chase produced no results. Besides experiencing our wonderful spring weather we are currently blessed with, hopefully they can shed some light on what is happening to my baby. As a test mule; however, I must admit that my impatience is beginning to show. Be that as it may, if they don't find the problem, it looks like soon I am going to raise the Lemon Flag. Now before anyone says something bad about the dealership, understand that they have traced 99% of the wiring and are doing all they can from their level-my hat is off to them.

 

Autocutter:

Just so you know, my C6 behaves exactly the same when I go to start it.

Rarely does it start on the first push of the button.

I usually have to let up and depress it a secoend time before it begins turning over.

Please let me know you find!
