Hey Everyone-

I bought a new 2024 C400GT from my local BMW Motorrad dealers about 1 a month and a half ago. Within 2 weeks of buying it, the scooter started leaking oil. The dealer repaired it under warranty. Then I noticed intermittent stalling on start up and oil leaking again. So, I put those issues on the list for the 600 mile servicing. Now, the dealer says that they can't fix the oil leak and that BMW wants them to replace the entire engine (under warranty). They ordered the engine from Germany, but they have no idea how long it will take for the engine to come in.

They offered to let me pick up the scooter and ride it with the leaking oil. But I decided that they should keep the scooter until they replace the engine. Just hoping that if and when I get the bike back, all will be well.

1) I'm sorry to hear that.

2) In case, as a new member, you haven't come across this yet, I wrote a couple of very long posts about a similar incident, two years ago: www.bmw-scooters.com/threads/bmw-swapped-out-my-used-22-c-400-gt-for-a-brand-new-23-c-400-gt-free-part-i-of-ii.2932/

The short form of this is:

- My '22 C 400 GT developed an engine problem -- drastic loss of power -- in May 2023, at which point I rode it home and didn't try to ride it again.

- Local dealer picked up bike in June 2023.

- August 2023, BMW NA or dealer or both agree to give me a brand new '23, apparently instead of trying to fix my '22.

- October 2023, I pick up my new bike.

One of the local techs said he thought a valve-keeper spring had failed, but that was sort of second hand.

3) I'm aware of only one other C 400 owner with an engine problem; see www.bmw-scooters.com/threads/engine-problem.3115/post-26845

4) I wish you good luck.
 
I have a 2013 BMW K1600 motorcycle besides my C650 scooter and there are many reports of catastrophic K1600 (6 cylinder, 1,600 cc) engine failures where BMW have had to replace those engines under warranty.

The C600/650 scooter engines have a common fault where the timing chain can 'skip' and destroy the engine due to a faulty chain tensioner design. The design was finally improved sometime in 2016.

FWIW I also own a 1969 Mercedes convertible SL and back in the day, Mercedes had to replace a relatively high % of engines under warranty, mostly due to excessive premature wear.

well, that sucks......
so, what is the dealer saying is the cause/reason it needs to be replaced for an oil leak???

They didn't say. Just that they are not satisfied with the repair and BMW decided to have them replace the engine. They ordered the engine from Germany but have no ETA for when it will get here.

Thanks for the info. I think my DH had read that thread. He thinks I will get a new scooter under the lemon law. Too bad that our state specifically excludes motorcycles under 750cc.

Thanks for the info. When I bought a BMW, I thought I was getting a high quality scooter. Now I am not so sure since they keep having engine troubles.

I don't think BMW produces bikes of particularly better or particularly worse quality than anyone else. In the absence of surveys such as the ones that Consumer Reports shows on autos, with tens (hundreds?) of thousand inputs, we may never know.

As I reported three years ago (www.bmw-scooters.com/threads/new-c400gt-owner-albany-ny-area-may-2022.2460/#post-21794 ), my buying a '22 C 400 GT (since replaced by a '23) had nothing to do with quality (perceived or real). My wife liked the ergos, I liked the pep and handling, and I was in the market for a new scooter with a generally competent local dealer and that was significantly lighter than a 650 Burgman.

That was pretty much it. Really nothing to do with quality.

I owned an R 850 R for three years ('97 - '00), and have followed BMW ever since, am a member of a couple of the non-scooter Beemer forums, etc.

In terms of quality issues, I had read for years about final-drive issues with RTs and GSes, for instance. And boxer-engine surging has been a prominent topic over the years, too. In much more recent times, I've read about gobs of problems -- perhaps more often than not -- with adaptive cruise on the top-of-the-line variants of those.

And then there's the issue of what I call "BMW being BMW," i.e., doing things just because they can, or just to be different, or just to show off, that sort of thing. I'm talking about such things as -- years ago, and only for a short time -- their implementing power brakes on some bike models; that made moving a turned-off bike around the garage an adventure. These days, you have what I think is a jackass move: the sideways Schrader valve positioning, something that I believe no other bike manufacturer does.

So, to my mind, BMW tries advanced technology more than most manufacturers, and offers a lot of features (with the exception of the C 400, anyway), but that's about it.

In terms of quality, advanced tech is more prone to failure, but that has nothing to do with drive shafts, for instance (and I believe that it was just within the last year that BMW agreed to periodically replace those on latter-year RTs).

Perhaps several decades ago BMW would have fared better than most moto manufacturers in a quality survey. Now, I don't see why it would. Our C 400s are made in a Chinese factory, as are chunks of their other models, many of which are no longer assembled in Germany, for instance. And this is true from Honda all the way down to, say, Benelli.

And we've all seen recalls on pretty much all brands, right? I mean, even Ducati for awhile couldn't make a gas tank that wouldn't warp with ethanol in it.

The other thing BMW is supposedly known for is cost ("Bring My Wallet" and so forth). In terms of initial cost, the bikes with advanced tech are certainly up there, but so are top-of-the-line Harleys, with just more chrome and special paint (and maybe a slightly bigger engine).

In terms of service, adhering my humble Royal Enfield Meteor 350 to its maintenance schedule costs about the same as my C 400 GT, even though the former cost about half the initial price of the latter. (I have a very competent RE dealer four miles away. At 77 now, I've farmed out any and all maintenance tasks on both bikes to their respective dealerships.)

So, in my opinion BMW's extra cost, like extra quality, is a myth, too, perhaps rooted in days of yore.

Corporate BMW itself, however, may still believe in these things. Otherwise, I don't understand how they expect to sell any of the C 400s in Europe and Asia when Voge and Zontes, for instance, offer pretty much the same or beefier scoots in the 350 - 400cc range, with more features (with the exception of a second disc up front), and at thousands of euros less.

In any case, those are my thoughts on this. I think BMW is not significantly better or significantly worse in terms of quality and cost than most other moto manufacturers, and if they have some particular offering that appeals to a buyer -- say, a C 400 GT in North America -- then that's reason enough to get one, just as would be the case for any other bike brand.

I would call corp and ask for a warranty extension since you are on hold for them and without machine… or at least get the request on- record now 🤔

That strikes me as a good idea: whether @missphy6 actually gets a warranty extension (which I think is doubtful) or not, at least she will be on record as being concerned about the problem, getting the problem officially noted on corporate's records, etc.

But I think a better way to start that process of getting things on record would be to send them an email, as that is a bit more "permanent" than, say, a jotted note about a phone call. The email in question, the one I used early on during my '22-replaced-by-a-'23 saga, is:

agree (y)
 
I was told that the 2025MY was put on hold in midsummer due to tariffs with China. I had to have my bike shipped from a "Sister Dealer" in Indianapolis to Minnesota. The 2025 was that hard to find. Not sure if much has changed in the last few months (doubt it), but I only bring it up because if they were to Lemon Law your scooter, you would likely be getting a brand new 2024 that has been sitting in inventory, which for you wouldn't be a trade down since you already own that model year. I wonder if a new 2024 is now low in inventory and why they are pushing to replace your engine instead of a whole new scooter. Worst case scenario, you could force the dealership to buy the bike back from you and they can make the repair and sell it used. You can then take you money and put it somewhere else. Just my two cents.

there is NO REASON to accept a lesser model year being there are plenty avail for shipment to the states.... now if you accept the lesser that is on you and YES they are different.... now you will have to wait a bit due to shipping but if that is not okay than bmw would be liable to replace your scot with cash/credit due to their terms.... the 25 was NOT on hold due to tarrifs it WAS on hold due to POOR sales AND the fact that they already knew there was to be NO 2026's sent to the states, so what was here was going to be it, and dealers knew it too but they of course did what dealers do and LIE to folks and say they are waiting on the order system to open up??? as mentioned, sales of these type machine are NOT what any manf wants so they are almost out of the US market completely, u can't blame them, why spend 10k+ on a scooter when you have ALL the m/c options that are avail for the same if not less cost(s)???
 
Its been a while since I posted. They installed the new engine for me and it runs great. I even went and got a custom seat for it so I can be more comfortable. :)
