Looking to purchase a 650, is it a can of worms?

[MBMW]

Currently looking at a used MY 14 650 with 48k km good condition inside and out with attractive price point.

Took it for an inspection all was good apart from body vibration at certain speed/ condition. Since the car was under watery (14 month remaining) the used car lot took it to the dealer who in turn raised a case with Germany. BMW authorized cylinder head job valve stems etc.!

I've been driving Bmws for a good part of my life never seen an engine issue at all not at this mileage. This is may 13 production car so N63tu which is supposed to have solved all issues with N63.

Question to all 650 owners in fact all N63tu equipped vehicle if I go ahead and buy it am I opening a can of worms? Will it continue to give me troubles and spend most of time in the dealer getting fixed rather than the road? I just got rid of an Audi S7 did exactly that transmission failed at 68k km and engine at 78k km bone stock.

Can't speak to your specific car, as there are always problem vehicles in any lineup, but the 2014+ N63TU motor has been solid so far with no commonly reported issues.

You don't want a 2013, though.

The 2013 has the same N63TU engine as the 2014.

yes, and there are a cluster of reported problems with it. Not so with 14's on.

There a thread full of reported problems, almost all 2013’s. Let me see if I can find it.

read the thread. There are 4 years of issues by at least a dozen people. It's not every 2013 to be certain, many (most?) are as reliable as the years that follow. I see you have a 2013 - I presume yours is one of the good ones. But as a consumer with a choice to buy a car that could have an issue, or to buy one year newer and have a lesser chance of an issue, its kind of a no brainer.

its kind of a no brainer.

Newer is 'almost' always better but the "brainer" part comes in when talking about individual cars and price.

With the depreciation on these cars, there is little difference in price at this point between 2013's and 2014's. 2014's have the added benefit of still being able to be CPO'd, whereas I believe the 2013's are past that, unless you are making a private purchase of a previously CPO'd car.

Lots of reasons to prefer the 2014 over the 2013. Only reason to prefer a 2013 is purchase price, which could end up being a very small part of your total cost of ownership.

[Giggs11]

You are right about the depreciation, and I will agree year younger car is always better than your older I guess but I was just trying to make a statement I purchased my new and after 52,000 miles just a regular maintenance I never had any issue whatsoever, hope it stays that way LOL, I know that M sport package and X Drive has nothing to do with reliability I just don't understand that the 2013 is worst then 2014 or 15 , in 2016 BMW did make some improvements as I'm readingEngine Wise and can't even remember the 2013 came with Customer care, but once again I could be mistaken my is late 2013 Production maybe that has to do with something ,One things for sure I have been driving BMW"s all my life And they were never known for being super reliable cars fast, sexy yes but super reliable no

Customer care was for the N63 motor, not the N63TU. You are right that your late year build may have something to do with it. Its been floated around that BMW may have been using some hold over parts from the N63 motor in the early build 2013's, since the symptoms were similar to the N63 problems (leaky injectors, bad coils, causing spark plugs to go bad). Luckily, the N63TU is NOT having timing chain issues. I wish they could find a permanent solution to the vacuum lines cracking, though!

Wishing you many more miles of happy motoring. I just cracked 75K on mine.

[Giggs11]

You are very correct BMW has a tendency to use older model parts on newer vehicles, so that could b the chase , in any chase is a beautiful car

[ezmaass]

I've now owned two BMWs with the N63TU - a 2014 550xi that I owned for 3 years, and now a 2017 650xi GC that I'm coming up on a year with in February. I've had zero mechanical issues with either car - granted, they don't get driven much.

I would feel comfortable getting an N63TUx powered car, but certainly stay away from the original N63... it was a basket case.

[ShakeDaddy]

2013 Model Year V8's do have the N63TU engine, with build dates beginning 7/2012.

I have an early ordered N63TU with a build date of 8/2012. Especially with my mods and BMS Stage 1 turned up to the 9 setting the car has been rock solid and very reliable. With the bumped HP, recently replaced with Bosch plugs and did a differential fluid change.

As mentioned in the attached Southey thread top tier gas with detergents is highly recommended. Also run a tank with Techron through every 2500 since day one with great results. 60+ months now of original ownership the car has been more than impressive.

So to the OP, with great past maintenance, the N63TU is No Time Bomb waiting to happen.

I hate that thread. It should be deleted, or at least locked.

[pepsih]

I just don't want to make another thread guys, But I'm in the same boat looking for a 6GC or convertible, 2014 and up since there was an update at that time, anyway, the car I'm interested in is a 2014 650gc with 62k miles on it. my main concern is obviously the lack of warranty(even if the dealer is offering me a 3k miles powertrain warranty at no cos)
You guys think it will be a good choice for someone who will DD the car and make roughly 15k miles a year in it?
Im planning on keeping it around 3 years or little less should I expect major maintenance (not talking about the regular ones like spark plugs, coils or fluids) or repair?

I wont beat the sh.. out of this car but occasionally i will press full throttle, I feel like the n55 engine would be enough for me but it seems that it is easier to find a well optioned 650 than 640.

anyway im looking forward for your input.
thanks

I wouldn't hesitate - just make sure you review all the maintenance records to ensure there hasn't been a history of problems with the car.

You may want to consider purchasing an extended warranty. It's a good idea on a car as complicated and expensive to work on as a 6 series.

The car that I am interested in was a CPO (was because as far as i know the CPO is not transferable if bought from a non BMW Dealer).
the car has been sold in 2016 CPO with 59k miles and now has 66k
So I believe if the car was able to be CPOed 7k miles ago it shouldn't be anything wrong with it am i right?

depends on what happened in those 7K miles, right?

You may want to broaden your search radius. There are a bunch of 2014's on and coming on the market as leases end. Most will have a lot lower miles than the one you are looking at.

I have early build 7/12, 2013 650 with 29K mi. Second owner, and CPO till August of 2018. No problems other than seat warmer element going out. We don't drive it much, something like 5K miles in last 2yr. When CPO runs out I'm on the fence about getting extended warranty what with all you read about the '13's. Probably cost at least $6K for another 4yr or so. In 4yr might have another 20K mi on it. Our BMW service rep is kinda saying paying $6K is not worth it with the problems he's seen on 650's coming in and the miles we drive. But what you read on internet says NEVER own one of these cars without a warranty. Trouble is 3rd party warranties have absolutely worthless reviews across the board.

In meantime I've put in Techron couple times now, I don't do hard acceleration that might foul an injector or plug and only drive it no more than 50 mi away from the dealer in case something happens. . . . kidding on that last one!!
