Buyer Beware!!!! Defective Car - Bad Care

Dissatisfied in Tennessee, 11/11/2018
2018 Mercedes-Benz S-Class S 560 2dr Convertible (4.0L 8cyl Turbo 9A)

I bought this car new in September from a Sonic dealership. Gorgeous car. By the first week of October, it was in the shop. The convertible top started to raise, then froze with the boot open. The top could not be raised or lowered. After 8 days, service manager of dealer called to explain that it could not be repaired, that this was a problem with 2018 S class cabriolets. He says that production has been canceled and that MBUSA had just bought about 10-12 of the cars back. I asked about a loaner and was promised one -- three separate times. I never got one -- apparently they know this will be a long process. Service manager advised that Mercedes wanted me in any other car ... just not an S class cabriolet. I researched and made a selection. At one point, my sales person even sent me a link to the proposed replacement car, at another Sonic dealer. After a couple of weeks, I called and asked where the car was. Difficulty dealer trading for it, I was told. Furious, I called MBUSA, who denied knowing anything. Then my dealer sales person texted that MBUSA was going to buy me out, and it would be an "ordeal." MBUSA denied when I called, said they had issues with the dealer, and said they would be back in touch. Days go by before I hear back (despite a promise to call me the next day). Eventually, I am told that they are recommending a buyout, but it will be 2-4 weeks for regional "approval." Fortunately, after pitching a fit, I hear the next day that I will be bought out, but it the process will be turned over to a third party logistics firm to handle. I got all documents to them within 24 hours, and have yet to hear anything; they advised process will take up to 4 weeks. In sum, I bought a new Mercedes flagship vehicle; it was operated over about 2.5 weeks before it ceased to function; my dealer tells me it's defective and promises a new, slightly more expensive and different car (but never responds to requests for a loaner); I call MBUSA; dealer and manufacturer point fingers at each other; eventually I am promised a buyout (MBUSA never answers directly the question of whether this is a recurring defect for S class cabriolets); and I am still waiting on my money, paying insurance since I still own the car, more than 5 weeks after the car left my possession and almost four weeks to the day I was promised a new car. I've owned a Porsche, a Range Rovers, BMW M3, 2 Audi A8Ls, an early Infinity Q45, and two Hondas in my life. All great cars. This has been the single worst customer experience for any product, let alone the most expensive car I've ever bought.

HATE THIS CAR, HATE DEALER SUPPORT EVEN MORE

I bought this car new and since the day I drove it off the lot it's knocked in the front left suspension and no one will attempt to repair it. They tell me they "can't just throw parts in the car" without replicating the sound. Well a technician heard the noises and said it's not the tires. Two dealerships recommended I change the tires to All-Season tires which I do not want on my high performance car. So they think I should be the one to "just throw parts on the car" to see if it fixed the problem? Are you kidding me?! Look, if they just made a reasonable attempt to resolve it, I'd be OK. But it's sad that I spent $170,000 on this thing with prepaid service and taxes, and they won't even attempt to solve it by changing out a shock absorber, bushing, or strut; even when the tech heard the noise and said "yep, it's not the tires". HATE IT! Probably going back to BMW. I have to be honest, if I wasn't having this issue for over a year now, the rating may be a 4 or maybe even a 5.

2017 Mercedes S550 Coupe

PhoenixGuy, 06/04/2021
2017 Mercedes-Benz S-Class S 550 4MATIC 2dr Coupe AWD (4.7L 8cyl Turbo 7A)

Interesting car category. It is not just an S Class Mercedes 550 Sedan with 2 fewer doors on it. It is very sporty, easy to drive, easy to enter and exit, and it is very sporty. I told my wife i was purchasing it and she was disinterested and negative that we needed it but when it arrived, she claimed it instantly. Not a high production car and you will not see it often. Could be classified as a dysfunctional car but we/my wife enjoys it.

My S550 convertible's transmission blew up (literally) on the way home from the dealer. With a new tranny, I drove 48000 miles and it is still running. Until recently nothing went wrong. Now the CD player (which I have never used) needed to be replaced and the remote trunk switch on the driver's door fell apart. The car is still under warranty but I have a bad premonition that the thing will get expensive. It is a shame since it is a powerful, comfortable and very impressive car and comparables (Bentley Continental?) cost much more. The depreciation is enormous - I paid 150,000 for it August 2016 and my dealer keeps on offering a current model with a trade in offer for 65,000 dollars. Update May 2021 - COVID sure put an end to cross country jaunts. I only have 55,000 miles on the car. It is running very well, no problems to report. Since it will not be produced after this year, I will hang on to it for the near future. One good thing about it is that Mercedes has a way of providing parts and service for their cars - of course they cost an arm and a leg, but still cheaper than one of the replacement models. November 2022 - l have just arrived at 69000 miles. New tires were needed, the second set - Michelin Pilot AS3 - lasted 30000. In the meantime, we took the car for a new cross country trip. I am doing the oil/filter changes myself but an air filter and new spark plugs are overdue and will be fiendishly expensive. Blowing the fuses for the electric outlets (my fault) was educational. One has to literally take apart the entire trunk to get to the fuse box (or the battery). Price of three fuses - 6 dollars. Labor at Mercedes would probably have been 4-500 dollars. Oh well. Otherwise literally nothing went wrong in 6 years. Trade in value? Probably $45,000 - an expensive indulgence, a Kia Rio would have been cheaper to have.
