Went to GM to get fobs reprogrammed, car started acting funny as soon as I left there. none of the personal options worked at all and by the next day the car was completely dead. the battery was drained nothing worked at all. I put a new battery in it and still nothing. It will not communicate with tech 2 GM put a new pcm in it and still nothing The guy at GM was trying to program my third fob to read metric instead of MPH he cleared them all 4 times and reprogrammed them again and then said it could not be done NEED HELP WITH THIS SOON!!

 

So it is still at the dealer?

 

its been there for two wweks

 

its been there for 2 weeks and they don't have a clue

 

The dealer has had it for 2 weeks and it is totally unresolved? They have no clues? What the heck are they doing? I would be talking to someone higher up the chain than the dealership if you have not done so.

 

I've had my 2005 C6 at the dealer four times in the last four weeks!!
Towed three of the four!

First week, wouldn't crank - they said it was a bogus error code and just deleted the code. It started then did the same thing the next week.

Next week (Tue - Thur) - replaced the PCM and ECM

Next week (Tue - Fri) - "steering column locked" replaced both FOBs

Same week (Fri) - picked it up from the dealership, drove to the nail salon, had it towed back to the dealership.

Saturday told me it was a dead battery and they were charging it but would keep it until Monday to be sure.

Monday called me and told me it was holding a charge just fine and no error codes. (I wouldn't come get it).

Tuesday I said I would come get it... Get to the dealership and it wouldn't start for them.

The tech and service guys are saying my car is possessed and they have no clue why it's doing this.

Sound familiar???


Any suggestions as a "higher up" to speak to and I am all over it!

 

Ask for the "Zone" Service manager for your area...

 

Just replace the BCM. Common problem, unfortunately on C5 and C6. Sh*tty Delco electronics.

 

Oh! Sorry... Just looked at the paperwork... They replaced the PCM, ECM, and BCM.

Maybe it'll work for Pasquale.

 

Its pasquale here(pat). Just got a call from the dealer, they disconnected my stereo system and car fired right up. They say it's a faulty radio, the system i have in the car is the touch screen with nav. system. keep you posted

 

hey 2525 is your car ok now??

 

Nope... Still in the shop - They really have no clue what is wrong with it.

Stay tuned!

 

Hey SLW2525,
What dealership is your car at? Better yet, Do you live in Florida? Because I know of a yellow corvette with the same problems down here in Florida.

 

I am in SoCal, Lake Forest, CA to be exact. Can you get the guy in Florida in touch with me through the Forum. I'd love to discuss this with him. (I believe Pasquale is in Canada and I'm sure he'd be interested too.)

Has your buddy resolved the issue or is he going through it right now too?

Oh! Just for a bit more info... I am at 33,300 miles and it's a 6-speed coupe.

 

Just got word that they believe it to be a faulty Cylinder Lock Module. They are ordering it and it should be in on Monday.

I'll keep you posted!

 

Did you take it in to the dealer because you were unable to re-program the car to recognize a new fob yourself (you just couldn't get it to work right)? Normally, re-programming for a new fob is something you do yourself.

If the dealership said they replaced the PCM (and charged you for a PCM in addition to an ECM) you might want to inquire about that. I know GM still makes references to a PCM but I believe there is no PCM, per se, in the C6. I believe the functions of the 'PCM' are incorporated within the ECM.

If you had no trouble prior to taking it in to the dealer...they obviously screwed something up. If they persist in saying they don't have a clue, I'd ask them about having another dealership look at the car. Saying 'we don't have a clue' is not acceptable...there is a solution. Maybe that would light a fire under them to trouble-shoot the problem.

Good luck.

PS A faulty cylinder lock...you'd think that would be the first thing they checked.

 

Its Pasquale [Pat] from Canada my dealer called yesterday and told me they disconnected the cable that goes into the radio and they hit the starter and it fired right up. First time in three weeks I guess alot of the computer works with the radio. If something is wrong with the radio the car will not run. Its in the manual. Will be in touch with 2525 Friday

 

Three weeks is a bit absurd. Regardless of the outcome I would find a new dealer to work on my car. Good luck!

 

 

For my situation, here is the whole story:

On a Wed. a few months ago, I was leaving work for the day, went to my car and pressed the start button. Nothing. Continued pressing the start button... Electronics would turn on, the battery gauge said 12.5, but the engine wouldn't crank (no error message displayed). I had it towed to my usual dealership (20 miles away, so I had a $91 tow bill.) They looked at it the next day and the error code that was generated didn't match anything in the tech's manuals. They called "engineering". The code didn't mean anything to them either so they instructed the tech to delete the line of code and see if it started. It did. They called me to pick up my car.

One week later, I left the office at lunch, stopped at a copy shop around the corner to have some copies made. Went back to the car, no start... Just like the week before (still no error displayed). Called AAA, requested another flat bed and had it towed to the dealership within my 7-mile range. They replaced the PCM, BCM, and ECM (if any of them are combined, then maybe the tech was talking over my head).

The next week, I drove to mom's house to take her to dinner. When I pressed the starter button, nothing. Pressed it again, nothing. One more time "Steering Column Locked" appeared but the car started. I called my normal dealership to ask what that meant and he stated, "Please bring me your car. We need to look at it as soon as possible. You may have a computer that is failing." I drove it up to them. After doing their diagnostics they asked for the second FOB to be brought to them because they felt there was an issue with the FOBs.

They called me to come pick it up... I drove off, went three blocks away to have my nails done and meet a friend for coffee (hour and a half). Got back in the car, pressed the start button... I wouldn't crank over. I called the dealership and said "don't go home yet, I'm having it towed back." (it was closing time.) In the amount of time that I was on the phone with the dealer (3 mins max) everything went dead. I was stuck in the car - I had to use the emergency release on the side of the seat to get the door open.

The next day, they called me and said it was just a dead battery but they would keep it over the weekend just to be on the safe side. On Monday (this week), they wanted me to come get it and I asked them to keep it one more day and just keep trying to start it. By Tuesday, they were convinced that it was not going to give me any more trouble so I agreed to come get it. So, get to the dealership, they go to get my car... Voila! It acted up for them!!!! (I knew if I left it there long enough it would do it again!!!!) They couldn't believe it. It did the several pushes to get it started then when it did, it gave them the "steering column locked" error.

So... after taking another day to look at it, they called yesterday to say that they were replacing the Cylinder Lock Module and it's on order, expected in on Monday.

The more I read about the steering lock issues from the C5, and that only the 2005 C6 has something similar, I'm sort of hoping this will be the end of the issue.

BTW~ Sorry this was sooo long! This is a wonderful forum!
