Default Help - Starter Issues

I'm installing my 3rd starter in a "08 Z51 6MT with 22,000 miles on the clock.
That's 7K miles per starter motor.
Is this a known issue?

Not a known issue that I'm aware of.

Have you made any attempt to diagnose the cause of the failures? Is the starter motor failing or the solenoid?

One option that came to mind is an aftermarket high torque unit. May be something to consider if you can't diagnose your problem.

Thanks for the reply.
GM keeps the old starters as core returns. However, there is an audible "thunk" (followed by nothing) which I believe is the solenoid engaging. The dealer thinks I may have gotten one or more poor rebuilds.
I have changed out the battery in the past to a yellow top - I had thought maybe that was the problem - maybe I was starving the starter for volts and over-amping the starter and a higher voltage "cold start" battery might be the fix but hearing the solenoid engage suggests that isn't the case.
I have asked the dealer's service manager if we can get the starter on the bench to determine where the fault is.

I would suggest to your dealer that if he thinks you may have gotten two bad starters, that he step up to the plate, refund your money for at least one and give you another starter.

Just my 2 cents.

Hey MiamiZ51,

I apologize for the inconvenience with your Vette’s starter. I understand this is the third time you have had to replace it; are you working with a dealership or have you been working on these yourself (I’ve read how savvy some of our forum members are!)? I will help to the best of my abilities, let me know if I can check into anything for you.

The dealer (Tropical Chev.) has stepped up to the plate and will discount the replacement by 75%.
The service tech noted that the new starter/solenoid had a different configuration from the one being replaced which itself differed from the original.
Of course, still gnaws at me that I can't figure out why this is happening.

I had heat issues with my starter solenoid. The nut for the +12 post was loose, though I don't know whether that was a symptom of heat. When I tried to tighten the nut, the + 12 post broke off. The plastic around the solenoid had melted. My thought is all of this was caused by my new headers (stainless with no ceramic coating, and I run it hard sometimes minutes before parking). Some say the loose nut is the cause of electrical heat on the solenoid, leading to the melting.

I recently wrapped my new starter, including the plastic around the solenoid, in heat shield material. Hopefully I won't have more issues.
