bmw really? The v8's have been atrocious - to your point google n63/tu/tu2 or s63 engine issues, injector issues, the dreaded CCP campaign and DTM drive train malfunction

 

@PeterUbers Great, that's good info. Goes to show most German brands can't field a good V8. The last V8 I owned was a boat anchor 6.0L Ford PSD. It could pull stumps out of the ground but had a laundry list of problems over 100k miles.

What's your view of the Porsche V8 in the Panamera or Cayenne GTS and Turbo models?

Every recent MB V8 has a history of grenading at low or moderate mileage. There isn't a clean one in the bunch. Maybe the M273, but that is on the edge of the "recent" descriptor.

 

porsche seems to hold the candle for reliability... Audi has been more reliability as well engine wise but the trans can grenade.

 

Another ME here except I work in/on SW.

Really sad to hear that the newer AMG’s are ticking time bombs. Or at least that this is the perception out there. Thought that was only a BMW thing. Which is partially why I went with an AMG vs an M6GC. Want to one day move into a newer AMG (GT63s &#128525.

I would assume the percentage of these failures would be pretty small. It’s like bad reviews for a business. I don’t always leave a review for a company/product (good or bad), but I would say I’d be more likely to type up a review if I was PO’d about something. Similar with forums, I would think a good percentage of the people who come here are either facing an issue and looking for help….ie something breaks and google issue xyz and it directs them to a forum where they post a question/comment related to said issue. This may give a perception that certain issues are very common. In no way am I saying there is no such thing as common issues with various products.

Crap happens with the mass production of anything and MB I’m sure has all the processes in place to minimize this as all manufacturers do. There is only so much any manufacturer can do with all the different constraints they have, especially when dealing with such complicated high performance machines. Do I wish there was a better solution from MB for these catastrophic failures tho, of course. Especially when you’ve done everything right (maintenance-wise). I do feel that slight fear of “what if something goes wrong” all the time and hate it (maybe I should see what all those extended warranty calls are all about lol).

Only way around all this i guess is to buy new-ish and sell once the warranty ends(too rich for my blood). But this would apply to any vehicle.

 

a red 2015 Wagon (Garbage) with 32K miles just sold for 90 + 5% commision on BAT today. If these motors were going BOOM right and left as the thread seems to make it look like, I doubt that wagon would have gone past 40

These are great cars and sometimes things happens. These 2 are the only ones that I have seen out of thousands sold that had engine going bad. One was tuned and the other one bought used so who knows what it went through.

There are many many E63s that are tuned and have done well and people continue to tune them.

 

There's also the chance that if something was better engineered to last longer and to be more reliable that the acquisition price of the new and used product would be significantly higher.... $0.02

 

Good discussions:

I have had great experiences over my life with MB.

But what I read scares me.
When OWNERS say it is OK for engines to grenade as it is OK and everyone else has failures too.

To me it is not all right for the engine too fail unless it has over 200K miles or abuse or just plain bad luck and not a common issue.

When owners do not ask for better nor care for better why would MB make it better?

MB seems to be doing too much CUSTOMER ENGINEERING like Chevy/Ford in the past.

These issues seem to skate by the leases and really only hit the used buyers or long term owners which - do not move as much $$$ into MB coffers as LEASORS.

 

good discussion indeed!

some owners are saying it's normal for a small percentage of engines to fail and that's likely within a better smaller percentage than other like manufacturers. Again we don't have actual empiric evidence/data.

is there a way for the following - and how?
a) Benz to make money
b) produce a good quality product according to your standards
c) maintain current or better prices

 

Peter,

How many failed V8-AMG engines have you come across surfing various forums in the past say 3 years? Honest question/

 

define "failed" and circumstances leading up to it for me

 

Failed as an engine failure needing a new engine. Tuned not tuned, bought used or new and the mileage the engine failed.

 

4 to 5

 

Do we have any common points among those failed engine? Tuning/Mileage/owners etc Without having more input hard to say if these engines are POS units or not?

 

I will say about the same for me as well (M157s only)

 

maybe 3-4

I also am an optimistic guy so I don't focus on the bashing threads as I used to. I may have missed some blown engines... most threads I gravitate to find a reasonable solution for m157 repair

Failures usually post 80,000 miles

 

Tuned, I'd say?

 

Yes and purchased with multiple owners on carfax... ymmv

I'm one of the few on here that bought this 2014 new ... and tuned after the b2b warranty was up

 

Yup- I had a S63 X5M that popped it's engine via spun bearings- warranty approved the fix though! Sold and bought a facelift w212 e63s...

 

truth.

 

This is all way overblown. There are exponentially more of these vehicles on the road than owners on forums. Engine failure is not the norm with MB vehicles. Forums have a habit of skewing and speeding falsehoods.

And the guy saying BMW, Audi, Porsche make better V8 engines has no clue what he's talking about.
-Every modern BMW engine in recent production sans the B46, so far, is an oil burning, oil leaking, weak rod bearing, timing chain stretching, turbo blowing piece of ****.
-Porsche V8's scuff the cylinders and burn oil, necessitating a new engine
-Audi V8's carbon up and need expensive "cleaning" procedures

Guarantee if you search forums as your source of info you'll find far more cases of the above than actual MB engine failure that isn't aftermarket/maintenance related.

 

+1000

my point exactly

 

Lol @ BMW

I came from an F10 M5 talked to a few shop owners about rebuilding my S63TU down the road and they both told me the motors blow so often than can't keep long blocks in stock.

Once my warranty was up I sold that car.

Haven't heard of too many unmodified m157 cars blowing up, unfortunately the OP is the exception.

 

Failures are overblown say the supporters. Where is the data to support the claim? Answer: it doesn't exist except inside MBUSA and Daimler.

Posters post issues and complain about the experience. Zealots respond by saying it's an anomaly, a fluke, and demand data to support the claim.

C'mon folks it can't be both ways. No one knows how widespread cylinder scuffing, or piston cracking, or 48V system failures are, unless you care to take the mask off and disclose your MBUSA or Daimler credentials, and post the warranty reports for all to see.

My view is much of the supporter reaction to reports of failures is driven by fear and remorse of having purchased a potentially very expensive mistake. Very understandable.

 

we also presume each person has the same threshold for what is "overblown"

everyone's metric may be a bit different.

 

Since you are so sure and confident of Mercedes being a Garbage marque, can you provide any data where the mercedes engines are exploding in normal driving? You must have some information to back up your claim, don't you?

I frequent many forums, BMW. Porsche, Audi to name few and it's the first time I am hearing the M157 engine is a tickling time bomb ready to expolde under 40K miles.

Please enlighten us with your data, no pun intended.
