Revival as I just did this on TWO Grp27s for my non-profit's '02 CTD. I had purchased them (MAXX) 3/30/23 and they were both testing bad approx 12/8/25 -- obviously being in parallel, one bad apple may have destroyed both.
I had my receipt and went into the Auto Ctr.
The woman told me I no longer needed that because it's all recorded by the serial # --
I know this but still save receipts to minimize any possible arguments of denial and/or speed the process.
They said they needed to test them and to allow 30 minutes. I expected as much. After 30 minutes he had one tested and confirmed it was bad. He quickly tested the second and confirmed it was bad.
I then went inside to the Auto Ctr register and
every employee had ghosted. After about 20 minutes we tracked down a mgr who can actually do the swap, who happened to be the very woman who told me I no longer needed my receipt.
She now seemed to indicate I absolutely had to have my receipt, but I try to just say as little as possible and handed it to her.
It took her a good ten minutes to ring me out and figure out how to waive the core charges. Again, I just stand there and smile -- laugh or cry is my mentality.
In the end, it worked out but allow a minimum of two hours for the experience. And hope they have replacements on the shelf. I was extremely lucky that they had two -- and only two -- Grp 27s in stock. I can only imagine the nightmare if they had to order something.
Here's my illustrious Auto Ctr -- for some reason I'm amused by all the protection for an old Hyundai. I'm sure corporate requires it, but it still makes me chuckle ('tis good to be easily amused)
