hey guys,

what is considered high mileage for these cars? i have a 2016 C450 that just broke 50k miles, and curious what i can expect to run the car to until i start seeing major component failures.
i come from a toyota truck background, and obviously i dont think luxury cars can be compared to long lasting toyotas that seem to never have issues after hundreds of thousands of miles.

can i expect to at least get to 100k with this car before it starts becoming expensive to keep alive?
what are your experiences with mercedes, what do you think?

@Skim450 Interesting the comment about Toyota trucks. I ran a 2005 4Runner to 205k miles and sold it for cash in 24 hours for what I thought was a strong asking price. I guess it wasn’t strong enough!

Mercedes and Toyota have nothing in common regarding achieving high mileage, unfortunately. MB seems to be designed to just get through the first 36 month lease period, then things get expensive quickly. Yes, an exaggeration, but far more common than one would expect.

100k miles should be possible, but MB does have many examples of major and expensive failures before 100k miles. These instances span across models and model years.

Rather than give a long list of specific and common failure for MB vehicles, I will say the M276 60 degree V6 is probably the most reliable MB has produced since the mid-2010s. And in typical MB fashion the M276 is now discontinued. Nothing like the Toyota 1GR-FE workhorse.

You have the 3.0L twin turbo V6, correct?

Keep the maintenance up to snuff is the best recommendation to achieve “high” mileage in MB terms.

 

thank you for chiming in Chassis.

and yes, this is correct. i have been doing all the recommended maintenance changes through MB since i took ownership of the car.

curious (and hoping) to hear positive stories of higher mileages.... lol.

 

Start doing some easy preventive maintenance like spark plugs. Check rubber hoses and belt for cracks and deterioration. If you haven't changed brake fluid, now is the time. Benz recommend every 2 years but that's in high humid location and some brake fluids lasts longer. If you can diy even better.

I have heard of several 90+k mile C400/450s with minimal issues. Typical W205 complaints are air suspension failures, pano roof failure and interior rattles. Nothing with the motor that i am aware of.
The M276 (both the 3.5L and 3.0TT) have been very reliable, and i believe the latest 722.9 trans has been proven for a lot of year across many models.

 

Just hit 66k on a 2019 C43 any thing I should look out for, all input is appreciated, diff oil already done, engine oil every 5k and I use 300V by motul sine day 1 and I only use 94 octane strictly and the transmission fluid changed at 60k

 

Dayummmm! That's some runnin' on a '19! Just about to roll 50k problem-free miles on my '17.

 

@RichardCranium i daily this ***** I’m probably the only facelift owner w this many/most kilometres, so il update everyone when the engine blows up, tryna rebuild it after I blow up it 🤪😂, the tranny however on these cars are ****ing strong 💪🏼

 

here's to hoping it doesnt blow quite yet.... cheers.

 

I have similar hopes, as well as similar experience with Japanese cars. We "re-homed" a 2002 4Runner with 180K miles and a 2001 LS430 with 157K miles when we purchased the 2015 E400 and GLK350. Both of the Japanese cars were absolutely bullet proof. The E400 is now at about 40K miles, while the garage queen (GLK350) is at 31K. Our usual formula is to buy nice cars and keep them a long time. When the annual repair cost (excluding fuel, oil changes, etc.) exceeds 50% of the actual cash value of the car, it is time to go.

We do have the MB ELW on both of these, so they are under factory warranty for 7 years from in-service date. After that is anybody's guess.

For me, the sad thing is that many of the cars I might choose to replace the E400 are now out of production. I do not want to drive a 4-cylinder car (not even a 4-cyl turbo), period. If I want to down-size, as I might, then there are very few 6-cyl cars to choose from. Other than AMG, no MB fits the slot. Lack of a desirable replacement might cause me to re-think the replacement formula.

 

@SteveE400 I like the replacement formula. That is approximately where we were when I sold the 2005 4Runner. It was solid as a rock and had many thousands of miles left, but required care and feeding to achieve it.

There is alot of plastic under the skin of a Mercedes, and some of it is "bio-degradable" and minimal (thin and lightweight) to begin with. Main examples are front underhood structure parts and wiring insulation.

Mercedes is a definitely cost-reduced product vs an early 2000s Toyota. Shame about the Mercedes price premium, one would think the product cost would be the other way around.

 

I have 65,000 miles on my C450 now, and overall, mechanically, I haven't had any issues (that weren't the direct result of a collision or some kind of physical impact). If you're going to be out of warranty, definitely don't open your panoramic roof, though...

As far as the rest, see the following (note, this excludes any kinds of rattles, creaks, etc):

43k miles:

• Auxiliary Battery Malfunction -- replaced (not an actual battery, it's a voltage converter/control module)
• Lane Keep Assist/Distronic malfunction -- control unit replaced (with the multifunction cameras)

46.6k miles:

• High beam assist malfunction -- fixed with software update in Front SAM

58k miles:

• Driver's door handle LED out

 

66K on a 2019! Lol that is insane.
i have about 9400 and probably 4000 miles were just driving for pleasure alone, no where to go in particular.

 

@AhEmGee had to get a baby amg Benz for the snowy weather as my daily or I would’ve bought the 63 Lmfaoo Canada ain’t kind w the snow bud

 

Wow. For once I'm not the outlier. 43k on the C43, 2019. I've been lucky, no real problems....one boost sensor, under warranty, and two blackout exhaust tips that were shedding the blackout. The runflats caused bent wheels which had to be trued-and I have Michelin AS/3 now...a world of difference. That's a runflat issue, probably not a "benz' issue.

The only issue I've had is the center display (between the dials) will very occasionally stall and re-boot. The SA claims I have four failures in the computer, but MB requires 10 to do anything....of course it won't do it when they have the car.

I bought an oil vacuum and did the 40k service recently, easiest oil change ever-new air filters too, they are kind of small for the amount of air, I'd replace them every 30k at the most....they were much dirtier than expected.

Pre covid I drove 30k per year, and bought the car....I'm optimistic overall....I did buy the benz extended warranty to 100k, just in case.

I had a 2003 BMW 330i manual that I got to 334k miles before rust won. Toward the end I was fighting dying plastic and rubber more than anything else, after poking around with the AF replacement, I expect that this car will be the same.....although I don't think keeping the C43 going will be a driveway project for me with a simple code reader, unlike the BMW M54 straight six, there is a LOT more going on with the Benz.....

 

What did you buy? Have link?

 

mityvac 7201 ? The one with the external pump. All in $140, probably overpaid, but I avoid Amazon. Grainger was the vendor.

 

@speedlaw Well done on the 300k+ mileage! How many years did it take to achieve, and did you put all the miles on the car? I’m going to achieve somewhere near 200k miles on my GLE, we shall see.

 

Wondering on the update on your car Mines is 2018 c43 with 20k miles any thing I should be looking out for ?

 

I am the second owner of a 2019 C43 currently at 69,000kms and I have encountered the following but replaced under warranty:

boost pressure solenoid valve duck sound issue - easy diy fix and the part was around $100
pano roof issues - replaced the front pano roof panel and it helped a bit
front valve cover leaking oil - replaced the valve cover silicon and that stopped the leak
condensation in taillight - replaced taillight
exhaust tip paint chipping - replaced exhaust tips

All I have done so far is oil changes and rear pads because the sensor was trigged but I will be replacing all rotors and the pads soon.

 

i have 1 2016 c450 with a JB4 running 91k until now with no issues at all.

 

2015 CLS400 4matic 107,000 miles
Issues
auxiliary battery malfunction- replaced
lane keep assist malfunction- vibrating motor in steering wheel stopped working
Rear axle seal leak- seal replaced
There was another oil leak towards the front MB fixed by replacing seal.
Coolant thermostat - replaced
Condenser has a small leak currently that I haven’t bothered to fix yet.
Car is tuned to 403whp. I run it pretty hard on some days and have had no major mechanical issues as of yet. Car has had all recommended services done at MB every 8-10k.

 

My wife's C400 has 122k miles, no major issues, but some stuff has started to show it's age.

List of major wear items replaced:
Motor mounts, trans mounts, front and rear drive shaft flex plates, re-seal of the cam timing covers.

The only MAJOR (ish) problem has been that the keyless entry and start function has stopped working.

The interior panel around the driver side seat belt looks pretty ragged, and the driver's seat leather is shot (no matter how much high end leather treatment I cared for it with).

Car was purchased as a CPO in 2017 with 2800 miles on it.

 

That is a lot of miles, hmmm I wonder why the keyless go stopped working, nothing showed up when you plug a scanner in?

not interference?

 

Yes, my wife had a 60 mile roundtrip commute for nearly 6 years so that really piled on the miles, plus many weekend trips
I'm not really sure what's wrong with the keyless go, I've checked both the fob batteries and the fobs transmit just fine when pressing the buttons.

I haven't scanned it since no warnings come up on the dash.
