Initial Quality or Build Problems With New E Class Coupes and Cabriolets

As we all start to receive our new E Class Coupes and Cabriolets there are bound to be problems. Hopefully any issues are minor.

The first problem I noticed with my E53 Coupe is that one of the rear seatbelt buckles is missing. Actually, it’s really not missing, it’s stuck inside the housing. It looks like the car was assembled with the buckle inside the housing and some disassembly will be required to get it out. I hope there aren’t any ather assembly issues that might be more critical. I rarely use the back seat. I accidentally found that the buckle was missing as I was covering the seat to transport my sons dog. In the car the dog wears a harness that we can attach to the seatbelt.

A minor inconveinence, but it will take a trip to the dealer to remedy.

What issues have other new owners found?

I might have said the same except, the first time I gassed up my E53AMG, I closed the lid and the electronics went dead, 100% dead. Eventually MB Roadside came out, jumped it, tested it, said there may be problems with the new battery, and towed it to the dealer. Later it was determined the battery cable was loose. That's all. Otherwise perfect.

On my E450 Cab, I’ve had two issues

1. Had the battery warning light come on. Dealer looked at it and determined that code needed to be re-loaded into one of the computers (?). Problem went away

2. Passenger’s front window was loose in the door and always caused rattling when driving and especially when closing the door. Dealer found glass wasn’t properly tightened in its holder. Fixed.

I’ve had my E400 Coupe since September, 2017. Other than noisy windshield wipers, which the dealer replaced at no cost, the car has been trouble-free.

Sometimes when setting off I get an on-screen indication that the rear seat belts are not fastened.... There's nobody even sat in the back...

My Easy Entry/Exit feature seems to not operate properly. I have it set to move the both the steering wheel and the seat in vehicle settings. The steering wheel moves as expected, but the seat doesn’t slide backwards to make entry and exit easier. The seat back moves up to a neutral position, but the seat doesn’t slide back. My dealer checked it out and said it is set to default settings. They asked me to bring it back with both keys so the feature can be set individually to both keys. I haven’t read that it could be set to respond in a different way to different keys. I’ll bring it in and give it a try.

The Easy Entry/Exit feature only moves the steering wheel up when you start/stop the engine. Unfortunately, it doesn’t slide the seat backwards, like the systems in many other cars.

Apparently not true for the 2019s. My steering wheel moves as does the seat back. The setup menu allows you to choose between only having the steering wheel move or both the seat and steering wheel. You can also turn the feature off. The owners manual clearly describes the seat moving. It mentions that it won’t move if it was already at the furthest rearward setting.

I have the same issue. Have the setting to both but the seat won’t slide back - and I know it’s not at the back-most position.

My driver vanity mirror light work intermittently, I'll have that checked at the 10K service, thought I had it fixed but started doing it again, must be a loose connection.

Same for me.

I have it configured for both but only the steering wheel moves.

Does the seat back (reclining) move? While my seat doesn't slide back, but the seat back moves up from my normal, slightly reclined position to a more neutral position.

Nope, the seat doesn't move at all.

My wife who is smaller than me says that both the steering wheel and the seat move for her.

So, either the car is sexist or it determines that my seat is far enough back already (although it can still go back much further).

I was always told that the C Class seats don’t move for Easy Entry/Exit so as not to crush rear seat passengers. The E Coupes have a sensor to stop the seat from moving back if there is resistance, so safety shouldn’t be an issue.

My dealer told me the Easy Entry/Exit feature is dependent on which key is being used to start and enter the car. I’m skeptical. I’ve never read anything suggesting this. I’m not sure if they fully understand what the feature is supposed to do. They told me to bring the car in with both keys and they would make the adjustment. I will try this weekend.

Yes, please let us know if thet’s realiy true... I was also under the impression that different keys don’t mean a thing to the car.

The car can recognize different keys and settings pertaining to that particular key. I'm not sure which settings are programable. It may differ from model range to model range. This feature has been available for a while. I don't know the programing process but I believe it is contained in the owners manual. Good luck.

I just used the other key and neither one will cause the drivers chair to go back upon exiting. The chair is not st the rearward most position. I double checked the setting in COMAND is correct.

I just got back from my dealer. The service tech and I spent a lot of time playing with the Easy Exit/Entry feature. The tech didn’t have any answers, but he did confirm my observation that the seat does not slide back as it should and that the seat back moves up from a reclined position when the car is turned off and the doror is opened, which he has never seen before. The seat back moving up from a reclined position may be an expected feature. It makes some sense that moving the seat back up from a reclined position would make it easier to exit the car. He is going escalate the issue and do so more research. Hopefully there will be an answer.
