AMG GT C coupe reliability
Hello,
I am looking at the 2019 AMG GT C coupe as a possible addition and would like some insight into reliability of the model in general.
I have researched it as best I can but have found nothing consistent to look out for (other than the usual creeks and rattles) which brings me here.
Any major engine/transmission/suspension issues?
All my previous cars have been Porsches (911s and Caymans).
Thanks.

Daily’d and tracked my pro for 12 months now 17,000km.
No issues except the replacement of a leaking strut. 100% my fault from the track or driving it in the snow.
Also, I drive mine in the snow with Alpins on.

On my 2nd now
I too daily mine 24/7 365. Snows are going on tomorrow. I do a bit of track prep (brake fluid etc) but that’s it. Never had any real issues with it. She’s solid as a rock.
You should be prepared for people staring, and most every time you get on the highway someone will be looking to go- this car gets baited like nothing else. Enjoy the car!

Mine has had several issues! They replaced 6 injectors, the brake rotors both front and rear, the high end stereo had wiring issues that caused it to howl at full volume, it rattles from all over, and now the car makes a tickling noise when turning right that it is going in for this week! It has spent a total of 35 days in service of the two years since new. I guess I got a bad example. I am not happy with the quality but I love the car.

My 2017 GT S was solid mechanically when I had it. Sadly traded it for a Porsche 718 Spyder a couple months ago, but the AMG was awesome and I would have kept it if I could afford to keep both cars.
I had the centre console replaced because the cup holder cover was sticking, and had a rattle from the hood hinge fixed with some grease. Under the first owner, it had an exhaust flap rattle fixed, again with some grease. All of these minor issues were covered under warranty. Never had any real mechanical issues.

There is probably not anyone else on this board with my experiences with cars, and while my 2016 has had it issues (The steering rack went with under 10k miles which would have been a 7K bill if MB had not paid more than half) both in and out of warranty. I am keeping mine, not because of its reliability (things like that are not factors for me), but because it is a unique machine that serves the purpose I have for it. I have owned 62 MB's and yes some were more reliable than others (my 2015 S class never had a single issue), and I would advise anyone with a monetary concern about repair bills to think hard before buying one out of warranty. Or look into aftermarket (or if you buy at a MB dealer extending the warranty) warranty companies.

My problem with my 18 GTC Roadster is pretty unique. I believe one other 2018 GTR had a similar issue but was found due to wiring and a GTS rental in Germany had the same issue happen, but no followup on the car was mentioned.
Differential lock would fail at highway speeds. The car would shift into neutral, not shift into drive, and thereby lose all power. This became pretty unpredictable as it would happen 5 miles or even 45 miles of constant driving. Each subsequent episode would happen with increased frequency. The car was in the shop 3x and the last attempt was to replace the Powertrain Control Unit (PTCU). Long story short, the process took several months and at the end it was settled with a buyback and replacement with a 2020 GTR.

You came out well, but kudos for you pointing out the car for sale with no mention of repair or lemon. Seems to me, that if this car was to get into an accident as a result of the differential lock error Shutting the car down at highway speed, would be a huge liability for Benz. It is remarkable that they would take this risk.

It is astonishing to me. If it was something minor like the car not shifting into drive - every other time - while stationary, I wouldn't be as bothered. But this issue almost got me into a wreck as I was changing lanes in front of a semi when it happened once. Interestingly the car is being sold as a CPO. Didn't think they sold GTs with that coverage.

Occasionally, I get weird electrical gremlins. Usually some system says its de-activated, once my drive mode selector went dark and I couldn't switch from C to I. I just turn the car off and re-start, and it's fine. This happens maybe 2 or 3 times a year. Not a big deal.
I often get the oil overfill warning, especially after a change - and it slowly gets less frequent as I burn off some oil. Both the dipstick and the electronic measurement are fine. This sensor issue seems to be common with these cars.

So far I have had the cup holder cover replaced, the center console lid replaced, and the stupid misfire about 10 times now ... I am bringing it to the dealership next week as the misfire is happening way to often now. I had brought it to them already and all they did was clear it and said it was normal for a car that is not used regularly. I drive it about once every couple weeks. I also had the stupid oil level to full warning ... very common.
The only real major issue I had was the dreaded drain holes blockage (convertible) causing rain water to get into the car ... that was fix by the dealership and cost someone well over 9K to fix.
