I'd suggest a phone call. Tell them you suspect the starter is not pulling away properly after releasing, and ask if there's any way they can rectify it.
A skilled mechanic, with some luck available, might be able to shim the starter to eliminate the noise.
Worst case, another starter. Somebody needs to cover the labor.
I have to go back in the morning to get the core charge refund, and thought I could have them listen to the starter then.
The rest of it will depend on how they feel about senior citizens, great-grandmothers and disabled individuals. If the response to any of the above is negative, I will email the company, follow up with a phone call and if necessary, write a letter. My last resort will be calling a local TV station for “intervention.”
I am not without “Plans A thru Z,” but I hate to use any of the ones beyond “A” if I don’t need to. I prefer to have them “suggest” a solution, and if it doesn’t agree with what I know so far, then I will do what I need to do.
I was a military wife for 30 years, a military mom and widow for another 20, and that brings me close to today. I can’t “do everything,” but I’m not dependent on someone else to do what needs to be done. Most of all, I know where to go for the information I need.
