My vehicle was due for A9 service at 70K miles. I have the 7 year 100K extended warranty. The service rep just advised me that my Engine and Transmission mounts have reached the point of where they are considered collapsed. It’s covered under warranty however parts not available in USA at the moment. Also my side mirrors would sometimes squeak when folding. They are replacing those under warranty too. I’m glad I bought the extended warranty but I’m scared owning this vehicle. MB quality and reliability has gone out the window. Ive had the vehicle since new, 4 years now. Vehicle is garage kept, 15K mike’s per year. Don’t understand how can the engine and transmission mounts to collapse. I would understand if it was a well used old vehicle but cmon now.

 

Sorry to hear. Engine mount failures seem relatively common posts on this site.

 

My E55 eats motor mounts every 25k miles but my GL450 is still on the original engine mounts with over 250k miles.

 

Are the engine mounts expensive to replace ? Is it a big job ? I wonder blue much it costs , if I don’t have extended warranty
Most likely to cost a lot more now on a GLE350

1998 SLK2502 different mechanics told me I had collapsed motor mounts and I noticed that I could feel the motor vibration, especially in reverse and when shutting off the engine. So I purchased a new pair online for $90 and the transmission mount for $18. Without the proper jacks to change them myself, I took it to Vaughn Motorwerks for repair. Labor was $200 (2.5hrs) and the car feels much smoother now. In case anybody is curious what collapsed mounts look like I've attched photos. Notice the oil that has leaked out of one of them. It was really smelly.”””””

 

In all reality, for a luxury vehicle, that is really cheap. The X166 is a great platform and affordable to own. Can't say the same about any of the premium MB's I've owned. Anything with ABC has been a nightmare and not just from the suspension. In my opinion, the X166 chassis is probably MB's most reliable and cheapest to own long term vehicle.

 

I certainly hope MB isn't unreliable- overall. I've heard "well you own a luxury vehicle, what do you expect?", and the answer is simple- it's quality and reliability. Who wouldn't want to pay Ford or Chevy prices for repairs if what they bought was frequently in the shop for repairs or expected to have reasonably priced oil changes. While owning a MB being a luxury vehicle is true, it shouldn't translate to "you're an idiot if you do own a luxury vehicle." Knock on wood, I'm seeing good reliability with my W166 GLE350 and hope I see continued reliability.

 

I've always thought that was a BS excuse for poor reliability. My 164GL has been great with over 250k miles as has been my three other X166's, 2 - 350's and 63. The two E's I've owned/own are/were super reliable but, as stated previously, the S classes have been very high maintenance and expensive to own. I'm a huge fan of the gas powered 166's. There is no reason an MB should be less reliable than a Hyundai or Kia.

 

- absolutely correct. That’s why I get “ are you crazy to own a luxury vehicle and pay exuberant prices for maintenance””. “”Get rid of it, it’s a money pit””
im starting to think it’s true. If I’m laying high pieces, the vehicle should be good quality and reliable. Unfortunately it isn’t. For me it’s a mute point. I’m seriously considering trading it for the Hyundai Palisade. Car and Driver review said that the Palisade is luxury compared to Mercedes. And it has better reliability and comes with 10 year powertrain warranty

 

You think the car isn't reliable because the mirrors squeak and the engine mounts are collapsed at 70k miles? The engine mounts are hydraulic.. it's a trade off. These should be viewed as consumables on these cars.

A Palisade will be a fine car, but a Mercedes it is not.

 

- no, it’s because I’ve had a lot of “cracking and pipping” sounds which turned out to be lose carriage bolts. 0 quality control. Now every year my wife GLC300 and my GLE350 gets a new battery, because Mercedes puts in defective batteries. Everyone dealership tests them, finds bad cells. What a rip off. I told the dealer there’s no way in hell, I’m paying for having defective MB batteries put in our vehicles. Don’t get me going with the AC mildew mould smell calls action law suit settlement, that MB denies, but quietly agrees to pay for services to those who are part of the law suit. Mercedes should learn from Hyundai how to make vehicles. If they do believe in quality and reliability, please MB , offer us a bumper to bumper 10 year warranty. I’ll buy two more Mercedes vehicles tomorrow. It will never happen because if MB did that they would go bankrupt, overnight.

 

Engine mounts are rubber, and a wear item just like your tires. 70k miles/5 years is about right for replacement. If you're too cheap to maintain a Mercedes, ask yourself if the few hundred dollars is worth your safety. I'd trust MB over Hyundai in a heavy collision.
We own 5 MB's in the family. My '08 ML350 has the highest mileage at 173k. It's been very reliable, and guess what, I put new engine mounts in it last year. It rides like a dream. Your W166 is just as good if not better. My friends Hyundai blew the engine at 108k and it's not even worth fixing. They are disposable cars.
Do you use the eco stop a lot? That may be why you're having battery problems. The oem MB batteries can last up to 7 years in cars without the eco function, which I personally cannot stand.

The U.S. Reaches $1.5 Billion Settlement with Daimler AG Over Emissions Cheating in Mercedes-Benz Diesel Vehicles

[size=16px]Daimler AG to Conduct Nationwide Recall and Repair of Mercedes-Benz Diesel Vehicles, Pay over $945,000,000 in Penalties, Perform Projects to Mitigate Pollution, and Revamp Internal Audit Procedures[/size]

- Mercedes-Benz agrees to massive settlement after mold found growing in HVAC system
Mercedes HVAC Settlement Website Sep 11, 2020
The Settlement provides two benefits to Class Members: (1) cash reimbursement for costs paid for repairs related to a customer complaint of moldy, mildew-y, or similar odor emanating from the vehicle’s HVAC system including cleaning the evaporator and replacing the filter, and (2) coverage for those repairs in the future. The percentage of reimbursement or coverage is on a sliding scale based on the age of the vehicle.

OK, so we have some with a stinky AC system. Easily resolved/cleaned but, admittedly, not up to par with standards. Not sure how massive the settlement is since I currently have two X166's and it hasn't been an issue on mine nor have I been notified.

On the OM642 diesel, they didn't go far enough on that engine. Check my posts since I've been very critical of the engine for over a decade and have warned all to stay away. MB's are not perfect and do have issues but not like we've seen in other vehicles. Honestly, if you want ultra reliable, get a Toyota Camry.

The issues you posted are not that of reliability problems but do I feel the diesel is not reliable. Goes to show that Hyundai has serious quality control issues and seemingly uses inferior engine parts based on the recall. Cars catching on fire due to engine failure at a rate high enough to force the NHTSA to recall is very very bad. Hyundai and Kia have come a long way and I generally like their vehicles but I'm not sure I want to go that route for long term reliability or safety. The 164 & 166 do extremely well in crashes and that's from personal experience. The previous generation X164 GL never had a death from an automobile accident reported. There are other safe cars but MB is at the top of the spectrum. Mercedez Benz GL-class - Deadliest (and safest) cars on the road - CBS News I remember that one of the deaths in the ML was from a person driving in front of a train and, if I recall correctly, was not wearing a seatbelt.

I don't hate on Hyundai/Kia. We've owned cars from them and they have all be great. I actually adore the Gen2 Kia Soul.

All of our cars have had AC mildew issues except the E-class, oddly enough. The Porsche had it. Our Toyota had it, so did our Lexus, and our Hyundai and Kias. The Benz is running a Mann Frecious Plus cabin filter which may be what is keeping it smelling so fresh.

The point is that this gasoline powered 166 chassis vehicle is reliable, but Mercedes is simply more maintenance intensive than most of the Asian rivals.

 

At this point Roni07 is just trolling, because he bought a Mercedes that he can't afford, like so many do, and he's not getting the answers here that he wants. You'll find him trolling the Hyundai forums in a few years when he's too cheap to keep that one going also. Perhaps public transportation is your best option Roni. I'm sorry I've wasted my valuable time and experienced opinions trying to help. You are a cheapskate and a thief of other people's time. Your mechanical ineptitude is also readily apparent. My last and final suggestion is to get those terrycloth towel seat covers for your Hyundai. I'd bet they'll fit your personality just perfectly, and it will protect your seats when you go to jiffy lube with your 10% off coupon.

 

What does the service rep know anyway?

 

I wasn't going to post any more, but I want Roni the troll to see this. Maybe it will save his life:

- My wife had the 2013 SLK 3 year lease and loved it. She loved to drive it. Turned it in, after lease expired.
- I came back from the dealer with a $2,880 warranty work performed on the vehicle. Thank God I bought the extended warranty. This vehicle is a money pit.
- engine mounts replaced
- tranny mount replaced
- L side mirror mechanism replaced
- R side mirror mechanism replaced
- A/ C Evaporator Mould issue

the service advisor told me, they are seeing a lot of the GLE 2020 2021 caking back with lots of Tech issues. she says they are trying to be like Tesla on technology but failing so far.

Now, my wife’s GLC300 started shaking when she turns the engine on. 36K miles and I guess it needs to have the engine mounts replaced too.
Mercedes quality is sliding downhill fast.

 

I agree, the 2020+ GLE's have been a nightmare!

 

167's in general. Roughest roll-out for MB that I can remember.

 

Tesla balks at touch screen recall, US agency takes action - ABC News (go.com)

Interesting that the screens are designed only to last 5 to 6 years? Really? Glad the NHTSA stepped in and forced the recall.

 

Motor mounts collapsed. Diagnosed by dealer. They want $3,844.19 . 2017 with 55k miles. This is not a "consumable" item at this kind of cost..

 

For my diesel MM is $180 a piece, so your model has to have them gold plated to make it $3800 ?
