I’ve identified at least five GLC63’s on autotrader that have a classification of “Branded Tile: Buyback/Lemon”.
Since my wife totaled (fender bender) our GLC43, I was looking to replace it with the V8. Can someone tell me what’s going on...that’s a lot of red flags.

Try pulling the history on those specific cars and looking at repair attempts. I'd bet it's due to the crabbing/tire skipping issue, which isn't really an issue but people cry and get the car bought back, and since it will fit the lemon laws in some states, they get branded.

I had that problem with my GLC43...I didn’t like it but as long as I was assured that it wasn’t defective, I was content. I loved the car. It was my wife who insisted that we pursue a remedy but she crashed the car before the dust settled on that point. She’s been “demoted” to a 2014 E550. Now I want the V8 (all mine). Trouble is I’ve now discovered even more Buybacks on Autotrader. Count ‘em 9! I’m surprised that, that hasn’t sparked more debate here. I am new to the forum however so maybe more research is needed.

One of the posted lemon cars claimed that a problem with the ECU had been solved and that it was still under factory warranty. I need more feedback here...I was expecting more people to chime in.

Nine Lemons out of 43 cars queried for 2018-2019? Where’s the forum on this?

I never even thought of looking at a used car in this way. I would buy like that all day long.

Funny story...one day I was walking out of the gym and walked upon a car almost identical to mine. I told the guy I loved his car(I was in my Audi) and he stated that he hated it, as the front tires slid all over the place when he turns in the parking lot.

I didn't really know what to say so I just said..."good luck puss..." and I walked away...

I would really like to see a breakdown of MB lemon/buybacks by model over the last couple of years. I have to think the GLE and GLC are at the top of the list.

In my research for a 63 (before I ultimately caved and bought a 43 to "hold me over") I too was coming across A LOT of the same. I was using AutoTempest (FYI - if you haven't tried it, I encourage you to - it aggregates cars.com, autotrader etc. in one place - brilliant) and found specifically one dealer in NJ who had an incredible selection of Mercedes models, to include a few 63's, almost ALL of which were MB "buy backs". The one catch - every single one had documentation and the full explanation of services and reason for the buy back. Overwhelmingly - it sounded like ridiculous things. All things that the dealer was able to identify and resolve but they bought the car back anyway. Seemed like a lot of ornery customers who refused to bothered and stomped their feet. It's a catch 22 for me. On the one hand, I can understand insisting on perfection from a 90k vehicle that claims "The Best or Nothing". On the other, what a bunch of B.S. to go through just to get in a new vehicle. Either way, I would still feel more comfortable in my purchase peace of mind buying a CPO car and sleeping better at night. Despite them still being under warranty, just not the same. That's my .02 and opinion only. I love being able to search CPO stuff on MB direct site. I spend a LOT of free time day dreaming on there...E63's, C63's and GLC63's dancing...

I don’t doubt for a moment that most Buybacks are reaquired for trivial reasons. You can get a sense of that from the reports. BUT, a friend of mine bought a G Wagon (buyback), hedging that the risk was minimal. He got burned and when he tried to sell the car he couldn’t give it away. So he kept it and ultimately spent thousands to fix it (I’ll spare you the details).
My main concern is if there’s a legitimate flaw in the model range that I should be aware of.

Based on his experience, and I'm glad you shared that, it sounds like a hell of a roll of the dice. If for no other reason than the resale issue. I've been pouring over the threads on here and can't find anything obvious that jumps out as a specific flaw or issue with the M177. I was actually shopping for a 63 when my wife and I picked up our 43, hence my similar experience in looking through the classifieds. Every time I get to drive my 43 "spirited" I end up asking myself, aside from glorious music it makes, why I need a 63? I honestly can't make use of 50% of the 43's capabilities as it is. I run out of road or close on traffic too fast as it is. Anyway, side track, off topic. I'm genuinely curious how your journey turns out. Please do keep sharing

So these vehicles are good enough for the "ornery customers" but not for you. "Ridiculous things" but you don't feel comfortable, so CPO only for you. Higher bar for you right? Since it's other people money and not yours, easy statement to make. Unless we have first hand knowledge, easy to sit on the sidelines and assume what is ridiculous and isn't. Go spend six figures, have reoccurring issues, and then come back and tell us how trivial they are after spending much of your time visiting your dealer.

That was literally my point; I could absolutely understand the frustration after the investment and insisting on better. Apologies if that read wrong. My wife and I had to lemon law a new car of ours a few years ago - it was a nightmare. I don't wish that on anyone. My experience though was with a 12k mile motor that had a rod loose it's bolts and the piston made it to the ground by way of a fist size hole in the block. They had the car for 60 days and that was a wrap. As to these 63's - it really is quite the interesting thing: There is one at Deluxe that states: "Please note that in May 2020 Mercedes-Benz USA reacquired this vehicle due to a customer complaint concerning Engine Function.Mercedes-Benz fully resolved this matter under warranty by simply Replaced Wiring Harness, the Vehicle Meets Acceptable Operating Standards. In the interest of customer satisfaction, Mercedes-Benz agreed to repurchase the vehicle." That sounds sketchy and expensive as hell. Then there is a MB dealer in IL who has no less than 7 of them in stock, all used, all super low miles, all super affordable. But none are CPO...why? No mention of buy backs so at a MB dealer but not CPO, that's worthy of concern, no? Personally, our 43 is our first MB purchase and just for the peace of mind we felt CPO was worth it to us. But again, that's just my perspective viewed through my lenses and with my checkbook. I wish I had the disposable funds to play in 63 land
