Customer service from Mercedes was great. The car was crap, and I'd expect the company that invented the automobile in the first place to have it figured out after 150 years. But a transmission starting to go at 90,000 miles, on a diesel no less, and then completely gone before 110,000 - when the service interval is 150,000 miles - is pretty pathetic, ESPECIALLY when you pay a premium for a diesel because diesels are generally more robust. And because the transmission is integrated into the anti-theft, Mercedes does not have to support the aftermarket. As such, the cost to repair exceeded the value of the car. Nevermind that to change the battery, you have to take out the seat, which wouldn't be a big deal except that that triggers teh airbag fault warning, which can ONLY be fixed by a Mercedes scan tool.
But yeah, customer service was great. Best thing about the Tesla is I can trade in the Mercedes, now. FWIW, I put in a used transmission. Wouldn't run. Talked to an indy shop who told me I was stupid for trying to do that, because the PCM wouldn't let teh car run if it didn't identify the transmission coded to the car (well, can't you recode it so it then looks for the new one? "No! I can't believe you bought a used trasnsmssion. I can't believe a place even sold you one. You just wasted your money"). So I took the computer out of the old (bad) transmission, put it in the new/used transmission............the PCM has no idea it isn't the original transmission, and the car runs fine, now. Granted, I would have be better off selling it as scrap when the transmission went bad than spending what I spent back then.
Anyway, counter-antidote aside, it has sounded for the past few weeks in the other thread that you have been very impatient with the dealer - I was surprised you even took delivery in the first place. Which I get, new car anticipation, etc. and all that. But be patient. And listen to them. For example, I was told from the get-go that the referral thing would take a while to get sorted. And my rep said it may be a pain, but she thought she could. So when I asked her if I should cancel the order and re-order through the link she advised me to wait, if I could hold off and let the credit come in up to a couple of weeks after delivery. Checked with her a few days ago.....still teh same thing.
Like I had said before, they have to get the referral thing sorted out. And a few other things. But this whole high volume thing is a whole new world. Think about it, they have increased their volume nearly an order of magnitude. "Production Hell" as Musk called it......and now it is "Logistics Hell." Tesla's customer service before the 3 came out, from my experience, was FANTASTIC. You can't have the volume increase that they've had without some growing pains. I, for one, am pretty darn impressed that the whole thing didn't implode. Tesla may be a decade old, but that is as a boutique manufacturer. They've only been a high volume manuufacturer for a couple of quarters.
