Major Repair for 2020 GLE350
Hello, I'm new to the forum and actually joined to provide a heads up to anyone who owns a 2020 GLE350.
Long story short, the line that feeds washer fluid to the rear wiper started leaking. We noticed a blue stain on the headliner on the drivers side just above the rear seat. It was dropped off at the dealer last Friday. They still have it. Not because the parts were not available, but because the ENTIRE interior of the vehicle had to be removed. All seats, carpet, interior body panels, head-liner, and center console. Everything, the service writer advised, but the dash. Even the brake booster and part of the brake system under the hood had to be disassembled in order to run the new line to the rear wiper. WOW! What an engineering feat. To replace a washer hose, the entire interior and brake system needs to be removed. I expressed my concerns to service department and they agreed that it was an engineering disaster to design it that way.
My service writer also stated that he hopes ours was a fluke, and that they don't see any more of these issues, due to the immense undertaking it requires to repair.
I contacted MBUSA Customer Service to express my concerns that our brand new $65k MB SUV with 6k miles on it had to be, in a sense, disassembled to repair a washer hose. My concern was met with attitude and brush off. The CS rep went as far as to advise me to take up my concerns with the service department. The CS Rep asked "what do you want us to do about it? It's getting repaired". She further stated that there was nothing she could do about how the vehicle was designed, which I understand, however a little compassion for an upset customer would've been sufficient. Apparently she doesn't appreciated spending what we spent on such a "marvel of engineering" only to have it torn apart by a MB mechanic at a dealership.
Our concern is that the vehicle won't be assembled as it would be at the factory. Our concern is that our vehicle interior was assembled by a mechanic and not factory technicians. Maybe our concerns are misplaced, but having the entire interior removed and replaced on a vehicle barely 6 months old is greatly alarming to us.
I went by the dealer today and saw the carnage first hand. The service writer advised that after several calls to Mercedes it was determined that a repair to the hose vs replacement would have been a better option. Mercedes advised since no such repair parts were available, the tear down and replacement hose was the only option. He said repairing the hose and splicing in a new peice would've taken an hour and would have meant only dropping down the rear of the headliner.
Furthermore, I informed the service writer that I should've been contacted and informed ahead of the tear down. Something as involved as removing the entire interior should've warranted informing the owner. Not after the fact.
Still no follow up from MB USA as I requested. Our first Mercedes experience is not going well.

The work done as dictated by Mercedes US is what needs to be done in their opinion to get the "job done right" - and you're right to assume this was a fluke deal with that rear washer hose since I have not heard this happening on this forum (I could have missed something) from W164's on up..
The interiors when assembled at Vance are done with primarily labor/airtool - unlike body panels which are done by "Kuka's" - and interiors aren't engines either - with proper tech shop time your interior can be reinstalled 100% to factory spec - this isn't rocket science - it's a question of tech labor time.
If you want to go for Lemon Law - best to keep records of the down time - and records when you get it back - and get attorney's opinion/assistance - "Lemon Law Replacement" is NOT something any manufacturer does willingly - and in this case your issues is not a safety issue ..
Inconvenient, but not unusual.

We have been promised the vehicle would be ready on Tuesday. A 12 day repair for a rubber washer hose. The service writer advised that a repair of the hose would have taken an hour. Apparently, MB has a repair kit forthcoming. So there may be others out there. The repair kit, per MB is not ready for release yet.
Edit: I just saw your pictures and if this was me I'd be so fawking pissed off I wouldn't be able to see straight!!!

For someone to say it is a "typical headliner removal" is unbelievable, wonder how they would feel if it was their car and in my opinion 6000 miles is a new car.
Neither the headliner removal procedure, nor the routing of the rear washer tube, are unusual. 20 year old Toyota SUVs have the same headliner removal procedure and rear washer tube routing.
This is a very inconvenient situation, for sure.
Did you mention if the service associate gave you a definitive root cause of the washer fluid leak? It could have been a pinched or cut washer fluid hose. Such a thing can happen during the assembly process, uncommonly and unfortunately. It can also happen when the component supplier ships to M-B a damaged fluid hose or headliner+fluid hose assembly.
The decision by M-B to field repair by splicing a hose section, vs installing a new hose, can be called into question. A new replacement part is always the better option. A field repair can fail in unexpected ways.
From reading this section of the site, it seems the V167 is having new platform teething pains.

It's not a simple headliner removal. I would not have an issue with the headliner removal. It's the removal of the entire interior PLUS portions of the braking system that are the issue.

And in my opinion, a car purchased in April of this year (6 months ago) is indeed still a new car. Maybe not by Kelly Blue Book standards but to the one making the payments on it, it most certainly is.

It's a low mileage, nearly new, car with a warranty repair that is time intensive to correct. Very annoying and inconvenient.
The work to rectify the defect is typical, and not unusual, for vehicles of this type in the modern era. Again, very annoying and inconvenient.

I view lease payments as a subscription service for transportation with the ability to travel when and where I want. I just have to add in maintenance fees as well.
