Default 92-93 Ecm Alert!

I have been waiting now for over a month for a warranty replacement (I had to wait over a month earlier this year also, and had to get 2 to get a good one - but it wasn't that good). My shop ordered thru a local dealer. They're not available. Now he's told that it'll be 3+ months until any are available!
I just filed a complaint with Chev Customer Service. They just confirmed that there won't be any available until MARCH 2007!!! I now have Richard Wagner's address and will be sending him a little love-letter regarding how well he supports the division's flagship car.
I had to pay $100 to get it home, then over $200 to have it towed to the shop. I've had to rent a car. Should I have to pay for all this because Chevy won't support my 14 year old car? That isn't very old in the grand scheme of things, if you ask me.
I had been planning on a C5 upgrade, but not no mo.

Most manufacturers won't support a car more than ten years old. That means all C4's are no longer cared about by GM.

I thought Corvette Central or Eckler's was supposed to have a good stash of ecms????? Maybe that's what depleted the supply?

Default Rebuilds are available

At least you can get the car running in the meanwhile with a rebuilt unit.

Default Where are the rebuilt ECMs?

My shop said they'd called all over the country and couldn't find any. And getting one thru GM means a rebuild also, since you have a core charge that's refunded when you return the defective. Right?
If you know where there's a reputable source for good rebuilds please advise.

Not "most manufacturers."

I had never heard of such customer abandonment until I bought the vette. I've owned or worked on most foreign brands, and you can get parts many decades after cars are discontinued.

For instance, when I was working on a 69 E-type around 1992 I could get parts from the Jag dealer.

I just checked an online Honda dealer, and they still carry a very extensive list of parts for a 73 Civic.

I've owned my '64 coupe since 1968, and some parts were dropped early by GM, but others are still available today from a GM parts department.
I think it depends on several factors -- example, how many vehicles were produced. I would think a low productioin vehicle might see parts dropped earlier.

I think most LT4 parts will disappear sooner.

Default '92 ECM Update

As noted a week ago I lodged a formal complaint with GM Customer Service about the lack of ECMs. Since then we've been looking for alternatives. Last nite I put the final touches onto a letter to Rick Wagoner - CEO of GM. I put it into the outbox at work this AM. This afternoon Brad called me and said he'd just received an ECM. I was able to retrieve the letter. I'll probably rephrase my concerns after I see how well the car runs.

Thanks to Brad at Brad's Custom Auto in Seattle, and Phil at Lee Johnson Chevrolet in Kirkland, I should have my wheels back next week.

That's probably because Jaguar hadn't upgraded anything in 25 years.
