GLE350 4MATIC ownership report




Vehicle: 2017 W166 GLE350 4MATIC with P2 package, trailer hitch, LED lights, and Parktronic, standard steel spring suspension with 20" 5 spoke wheels. Black exterior and black MB-Tex interior. I purchased the vehicle pre-owned with 3,000 miles on it, and it has been dealer serviced during my ownership. It is now coming up on 30,000 miles.
Overall, I really enjoy this vehicle. I came out of a 2011 VW TDI Touareg that I put 238k miles on. I use a vehicle for highway cruising, both for work and for family trips, so comfort at speed and luggage capacity are priorities. Towing is another priority, because I pull a 3,000lb boat a few times each year. I have run several vehicles beyond 200k miles, and am familiar with what it takes to achieve high mileage, and I choose vehicles based on the potential to achieve high mileage. I prefer the German design ethos in vehicles, and have several German brands in the family fleet.
The GLE350 is a comfortable highway cruiser; it swallows up luggage, and tows a boat well. Suspension and seats are excellent for long 700 mile trips at 70mph-80mph. The climate control and infotainment systems do their jobs well. Towing is a very stable and secure experience, with capable steering and plenty of power. The Mercedes exterior appearance, while subjective, is a positive for me. Quality of materials and interior design are excellent, and body rigidity is very good. MB-Tex seating surfaces are rugged, comfortable, attractive and easy to clean. Subtle details like placement, direction and intensity of interior lighting are pleasant surprises. Use of interior dome and reading lights by passengers is possible, without detracting from the driver's night vision. This vehicle seem like it will be reliable, based on only one warranty claim so far - for a cracked wood door trim panel.
One of my favorite features of the vehicle is the harman kardon audio system - it rocks.
A few characteristics are, for me, neutral and unimpressive. The M276 3.5L naturally aspirated V6 gets 22mpg on the freeway, in the best of conditions. This is not impressive. I use 93 octane fuel, exclusively. Braking power when towing leaves something to be desired. The 7G-Tronic can be clunky in certain situations. 20" wheels and tires are not comfortable on poor surfaces, I know of no other way to say this. The Conti Cross Contact LX Sport tires have mediocre, at best, tire wear.
In summary, I am a generally satisfied owner, and see that this vehicle can run beyond 200k miles, with the necessary maintenance that all vehicles require.

Next year I believe I will replace both for just one - and the likely candidates will be (all used) a Cayenne (non-turbo), Toureg Executive, or a GLE 400.
i like the idea of the GLE400 as it checks all the boxes for me in my mind that combine the two cars. Turbo, cargo, smooth, classy, comfortable. I really do enjoy what a turbo does to a torque curve. I need the ability to use for Home Depot duty sometimes, and need the ability to haul around a bunch of arrogant bankers in downtown DC too (note, I’m one of them, ha!).
Any major flaws with the 400 motor or GLE design? On the E sedan - it’s bent rims and a laggy transmission mostly.




The 3.0L V6 turbo is on the M276 architecture, a sound engine that has been around for a while. The unique induction and turbo system is used several vehicles. There don't seem to be widespread problems reported on this site relative to this engine.
The GLE400 uses the 9G-Tronic transmission, used for a number of years on several M-B vehicles. Average or better M-B reliability.
Major flaws? I would say no.




The tires are near the end of life, with 30k miles. They are pretty noisy and slappy now, they are the factory Conti LX Sports. I will probably replace them with the same tire at about 35k miles, or 40k miles if I can wring out that many miles. I run 45psi cold inflation pressure on all four tires. It results in 48psi-50psi warm pressure, depending on ambient conditions. I run the pressure because the far too low M-B specification was resulting in uneven tread wear.
Brakes are nearing the end of life. I can feel pedal travel and fade increasing.
We did experience a cracked windshield, from a seemingly small stone impact. I am in the middle of a painfully inefficient three way discussion between State Farm, the M-B dealer and a third party glass installer. I am insisting on OEM M-B glass, and this is causing headaches, mainly for me. I will report back when it's resolved.
30k service appointment on Monday at the dealer. I am in the market for another three-pack of prepaid maintenance, and most likely will not purchase an extended limited warranty.

I know it is not a GLE but ML. Surprised you run the 48 plus psi in tires. I have 2015 ML 350 with over 64,000 miles and have always run 36 PSI. Got 41653 off first set of tires and still on original brakes and pads ( no brake warning light yet. I know many owners are confused on the psi stickers, ie the one in the fuel door which state max psi vs the ones in the door jam I kinda split the difference.
It has been a trouble free vehicle so far car, ride is a little bouncy. Expect to keep it for at least another couple of years. Only wish it had park sensors and all around view camera.




After inflating to 45psi cold, wear has evened out. I measured 5/32" tread depth today on all four tires, measured at multiple points on each tire, in each tread groove.
I will run them to at least 3/32" and, if the tires make it through the winter, to 2/32" in the spring. They are noisy and slappy now; quite noticeable that it's almost time to replace the tires.

I drove a 2020 GLE350 as a loaner, overall it is a nice update to the platform but doesn't give me the desire to go out and get one. I like the W166 a lot.
Positives of the V167 2020 GLE350:
- MBUX is great, specifically the display screens, content and mouse/trackpad. It is now on par with BMW iDrive and the latest VW system.
- headlamp styling/motif is nice
- forward visibility seems improved
- center console cupholder seems larger
Neutral or negative:
- ride seems squishier and less direct
- seats are less bolstered, base seats in W166 vs V167
- center console hand grips obstruct view and access to the cupholder
- interior door handle is moved rearward, making it more awkward for my body size (6' tall) and seating position
- 9G-Tronic holds gear far too long after throttle lift in aggressive driving, both in comfort and sport modes. My view is that M-B should leave all aspects of transmissions to ZF and Aisin who are the world leaders in that technology.
Later this week the windshield will be replaced because of a crack suffered last week. The glass shop assures me it is a dealer ordered Mercedes OEM item. We will see.

The Best of Mercedes & AMG




Temps were in the upper 40s all day, and it appeared the work was done in a heated shop. The vehicle was parked outside when I picked it up late in the day.
The G. Daimler decal is in the lower right, and part number information in the lower left. When I have more time I will read the service write up in detail and post the part number used.
How long does it take for the urethane "bedding" to cure?
I am really getting to like the base MB-Tex seats. I drove my wife's G01 X3 with sports seats today, and earlier this week I drove a V167 GLE. My two year old base MB-Tex seats felt like a comfortable pair of jeans, when I left those vehicles for mine.

- State Farm, the entity that holds my policy
- Link, a company to whom State Farm outsources glass claim processing
- local glass installer who did the work
- local M-B dealer who says they "don't do windows", but did calibrate the adaptive hi beam camera and rain sensor for the glass installer.
I don't have active speed limit assist.




Repair kit 0009894905
Xentry calibration of device A40/11 mono multifunction camera
Options on my vehicle:

Not present on my vehicle:

513 speed limit assist
628 adaptive high beam assist plus
What does 628 do?
I'm concerned about reliability with the car. I am just at 27k miles and when I turn on the car I always hear that the suspension is creaking a little. It concerns me but I will have to take it to the dealer to get it checked out. I can see this car getting to 40k or 50k, but I feel like there will be a lot of costly repairs after that mark is passed. Thoughts???
The 7G-tronic transmission is not as refined as it should be, especially for vehicles that cost $50k+!!! You can really feel the shifts if you drive fast, and they kind of throw you back into your seat. Not as luxurious as I had hoped.
I don't think it handles bumps as well as other luxury SUVs, but still handles them well.
Handling is what you would expect from an SUV that weighs as much as this car does that isn't a Tesla haha.
Gas mileage is absolute garbage but that's not why I got the car haha. Really cool that you use 93 octane fuel though! I use the 91 because that's all we have in Los Angeles, but even if it were available, I would use 91 because of the gas prices here. Is there any reason that you use 93? Do you notice a difference between 91 and 93?
The tires really suck! I just took my car to the dealer for an issue, and the tire specialist measured the tread on my tires. It is really really low! When I got the car I was told that the tires should last up to 50k miles, but it's only been 27k miles and I might have to get them replaced. It is a lease and I wish to return in (lease ends in June), but I don't want to have to buy a set of 4 new tires for a car that I'm not going to keep! One of my continental tires had an issue with the sidewall, so I bought another tire that still fits the car (for the right rear wheel). I don't remember the brand or when I got the exactly (will update if I can get that information) but they have worn pretty terribly, too. I come to find out that Mercedes **APPARENTLY** does not rotate your tires when you get the vehicle serviced and that you have to pay a fee to get them rotated (which I think is insanity). Not sure if I made an error somewhere along, but I though that the tires were being rotated every single time I took it in for service (every 10k miles, about once a year). My tread on one wheel pretty bad, and I'm a little worried when I drive the car. The tire specialist told me that they only thing that should be affected is the braking distance and that the traction is not as concerning right now. Anybody else been in this experience or have any comments/advice?
Thank you! I really appreciate it!
This is now the situation with majority of today's autos. Brought about by cost cutting and the ever increasing speed of vehicle assembly lines.
We saw the need therefore to re instate from the early 90's once again full, precise adjustment. Essential front Camber and Caster "allowing to adjust tire contact angles". Catering for other than showroom's height conditions.
Day to day commuting encountering high cambered roads. Wheel squat through load carrying or lowering, fitting wide profile tires/wheels, curb knocks. Correctly resolving steering pull.
No more going trips from one dealer or alignment shop to the next or constantly changing tire brands in the mistaken belief that is the cause.
Investment of $380 for front kit prevents costly, premature edge tire wear by providing precise (ongoing) adjustment of both Camber and Caster (up to 1.5 extra degrees Positive or Negative).
This (P/N 504016-3 J) kit simply replaces the upper/inner wishbone mounts (bush extraction tool included allowing kit to be fitted without arm removal). For the rear, there is adjustment OEM KMAC rear kit "doubles" the existing rear adjustment range. Also at same time replacing the highest wearing bushings and is precise single wrench adjustable. Bush extraction tool also included. P/N 504026 K $480
Another KMAC kit manufactured is front Camber and Caster kit that replaces not upper, but lower arm bushings (4). Advantage here is that also replaces at same time the rear inner bushes which are the highest wearing and OEM are expensive to replace! Also includes bush extraction tools P/N 504016 M $595

Tire wear is interesting. I was experiencing shoulder wear on both inner and outer shoulders on all four tires, until I increased inflation pressure to 45psi cold. The uneven wear went away. I have 31k miles on the tires now, and should be able to get approx 40k miles out of them. They are noisy now. I pay the dealer to rotate my tires at every service.
What options do you have on your vehicle? 20" and 21" wheels are noticeably less comfortable than smaller wheels. Air suspension may help with this. I have a non-air suspension, and ride is harsh over cracked pavement.
Another factor affecting tire wear is assist systems such as active lane keeping and cruise control (both standard and Distronic). These systems use the brakes and can have an affect on both tire wear and brake wear. The only assist system I have is standard cruise control, which employs the brakes when the set speed is lower than the current vehicle speed. I set cruise control when the vehicle is near the set speed, to avoid unnecessary brake pad usage.
After 14 months of owernship, a report is submitted herewith. I will update this over time.

Why do I do this? Because 93 is every brand's premium gas (at least on the East coast), in which the gas companies include their best additives.
I have been using strictly 93 octane gas in every vehicle I have owned for the past 30 years. (I also always change my oil with synthetic oil for all my cars.) During that time I have had literally zero engine problems with any of my cars. And I don't buy new cars all that often. Some cars I keep for 12 years or more and put 150K-200K miles on them -- and I don't baby the car when I drive it.
If all you ever do is put premium gas in your car and change the oil regularly with synthetic oil, you may never have an engine problem again. That's my rule of thumb anyway. Cheers!

My goal is long tread life, and cost is a secondary objective. How is the ride comfort, noise and handling with LX 25 tires?

My goal is long tread life, and cost is a secondary objective. How is the ride comfort, noise and handling with LX 25 tires?
A question I have is, do I need to go with a "MO" labeled tire?
I'm not sure why the dealer was so hung up on that and wonder if it's just something to be concerned about while under warranty or if that designation has significance to handling and/or the safety features.
***UPDATE***
This is just one viewpoint which I happened upon trying to dig into the matter.
From the Discount Tire.com website:
"OE TIRE CONS
Here's the other side of the coin. If you've put some mileage on your vehicle and you're looking for a little something more out of your car or truck, tires are a great way to pretty drastically alter its handling, road noise, comfort and fuel-saving characteristics.And before you reconsider the tires your vehicle came with, be sure to check them with a tire recall search tool so you know you're getting the safest and most recent version.
The moral of the story is that you should by no means feel pressured or compelled to replace the tires your vehicle came with for the exact same ones. So long as the new tires have the correct width, aspect ratio, rim size, speed rating and load carrying capacity you’ll be fine."

The only reference I can find in my 2015 ML owners manual to MO is MOExtended tires(.On page 292 )of my ML350 This MOextended is for runflates. I have no experience with them but many people do not replace runflats with runflats and go back to the normal tire. Not sure what came on yours. But if they are not runlets, just go with a tire that meets those noted in door frame and owners manual. The owners manual give you an idea of other size tires ie rim size that comes on your car.
