GTR 2020 broke down after 200 miles
The rear steering module failed and i got more than 13 faults.
Asking the dealer to unwind the deal since for 203,000$ car these things shouldn't happen. The service advisor did told me that they see more of these coming lately with various issues.
I've purchased the car from Fletcher Jones in Fremont California (Authorized Mercedes Dealership).
They refused to unwind the deal.
That car depreciation curve is insane so selling it right not will be horrific. Bad feeling, MB should learn how to build better cars especially with such high price tag.
I owned several Porsche's and never had ANY issues, wanted to give a try since the car drive awesome but seems to fail short.
I had previously own GTR 2018 that failed miserably with AC compressor twice, i traded it for the new one which turned to be another shame.
They look great, i would suggest to wait and stay away for now.
MB bad quality.

Price has little to do with reliability. If anything, more expensive vehicles tend to be more complicated and lower production volume, so they have more issues typically. Porsches are not immune to issues either, and they build an order of magnitude more cars on the 911/718 platform than Mercedes does on the SLS/AMG GT platform.
My own AMG GT S was pretty reliable without any significantly issues.




Since your problem occurred when the car basically had no mileage on it, and usage is determined by dividing the mileage where the problem occurred by 120,000, you will eventually get your full purchase price plus taxes and license back if the car turns out to be a lemon.
Do check out and see if they can fix it, and you'll have Cali lemon law protecting you.

The majority of the GT Rs are going to be very hassle free, and for those that aren't, they should all still be under warranty.

That being said, I would let the dealer fix it, this could be a one-off and you would never need to worry again.
Expensive cars have more technology, exotic materials, and more to go wrong.
I cannot comment on Porsches specifically but I can promise you there is nothing reliable about BMWs, Ferraris, Lamboghinis, very less so with McLarens and Aston Martins.
I think the GTR is a phenomenal machine and you should give it a chance.
BTW, Mercedes after sales service at the right delaership is legendary.
They have fixed cars outside of warranty on goodwill.
And I had a full extra year of warranty added for free on my car when something went wrong and a part was on back order for 2.5 weeks
Stay safe

Hope you dont end it up like this.
but looks like you are not the only one




Things being faulty from the factory can happen. That's what the warranty is for, and as mentioned above if you got the short end of the stick and purchased a lemon, that's what the lemon law is for. Chances are they will fix your rear steering module and that's the last you'll have to deal with it. Pretty much every car I've purchased new had some issues from the factory. All dealt with under warranty and I moved on enjoying the car. One of the benefits of AMGs is that many of the components are shared across many of the models. The engine is largely the same in all V8 models for example, so it gets a lot of real world testing and is rather bulletproofed. So are other complex systems like the rear locking differential etc. The rear wheel steering is less widespread at the moment, so probably more prone to unknown issues, but again, that's why you have a 4 year/50k warranty.

thanks, the fault is the steering rack according to the service advisor. They are waiting for parts.
i understand that it can happen to any car (Including Porsche As you have mentioned with the GT3 2014 - 2015 finger problem where Porsche gave 10y of warranty to the engine).
‘’however I owned 6 911 including one 2015 gt3 that had the finger issue and was fixed. With the GTR I owned one 2018 that had recurrent issue with the ac compressor from day one and this 2020 which started seriously bad. That’s 100% fault over 2 cars , silly me for trying it fort the 2020, need to swallow the frog and let them fix it.
im defiantly started to monitor and document and will go for the lemon if will be needed.




One recent case, this poor guy's car has been sitting at a dealer's repair bay since the 7th. The car is so new, the dealer tech cannot figure it out and cannot even get GM's tech hotline to answer the phone....it happens!

got the car out , so far so good . Going to get some miles today to see how it goes.
With regard to the GTR context, the service advisor told me that they never saw rear steering problem however it’s new to mb so it’s not surprising, still annoying.
If you accept long service time you accept mediocrity.

on my 5th lambo (brand new evo rwd) after performante, lp570, Superleggera 08 and Gallardo Se06
i did over like 40k miles combined on all
road trips all over us in my Superleggera never once had to go to shop, any of the cars for a repair, ever since 2012
they are the most reliable super cars/cars I’ve ever owned (over Porsche Ferrari lambo) and mercedes
mercedes for me have been pretty rock solid, I did have some nagging battery faults in gtr which got sorted after a few times but never a mechanical/stranded failure and it’s driven hard hard
my gts never an issue, s550 cab, gle glk etc etc never a repair ever
you just have horrible luck of the draw and I’m sorry for that however all of these mechanical cars can have issues and you just never know which side you fall on, unfortunately
try to have it fixed and hopefully you can enjoy it, it’s an amazing machine as you know !! I was behind frustrated with the battery issues however I stayed calm worked with amg tech and service few times and we got it sorted
all the best
