I know there’s a million threads out there about these issues.

But I Have a 50e… got the drivetrain issue.
Dealer is willing to work with me to get me into a 40i or m60 since they can’t figure out the issue and it’s my 4th CEL in 6 months of ownership.

I’ve seen some posts of the m60 also having the issue of drivetrain malfunction and some gear selector challenges?. Very few on the 40i.

At this point I just want a vehicle that works. The 50e has been such a let down. 10/10 when it works, but hard to continually just have it at the dealership every month.

Would prefer the v8…. But if we are seeing these issues, then rather go with the 40i and have a vehicle I can have in my possession more often then not.

M60 owners… how has the experience been?

Unless the dealership is giving you back all your money (which I'm sure they won't), I would be very leary of what they are offering you. Getting out of a vehicle so soon can be extremely costly in terms of depreciation.

I have the 40i and came from an M850i which had the V8. I'm more than happy with the 40i and don't miss the V8 at all.

Where in Canada are you?

A dealership worked very hard to get me out of a plagued G30 540i back in 2017 which included very little on their end. Wait for their numbers before getting your heart set on this.

My M60 has been flawless. I don't agree with some of the programming but that would be across the board. As for the car itself, it's been great.

Historically the 6 cylinder is the most trouble free engine choice. Though I don't think the 8 is too finicky anymore.

B58 (the engine in 40i) is bullet proof and super reliable. I would go with 40i tbh

I’ve had my M60i for 7 months and have ~11,000 miles on it, haven’t had a single issue. We’ve taken a few long distance road trips and loved every mile driven. IMO if you want the fuel efficiency of the 50e go with the 40i, if you want the acceleration/performance of the 50e, go with the M60i. Another thing to think about is the packages available - if you had the Executive Package and CCP in your 50e, it’s hit or miss to get in the 40i, but you can definitely spec it in the M60i. Plus carbon fiber trim is available on the M60i

Both vehicles aren't known to be suffering from any chronic issues like the 50e. As you've likely noticed, modern vehicles have electronic and software issues far more often than mechanical ones.

If you want the M60, go for it. Nobody ever regrets getting a more powerful and more fun car. It's just a question of if the financial side of it works out.

In Calgary

Pretty much what they’re offering me is

10k below what I paid - However the new car is being discounted 6,500 + covering the Lux tax. I have 6,500km on it, so all in all, even if I have a crap car and BMW agrees to buy it back, I don’t think they’d give me much more.

While the plan was to keep the 50e for a while, the fear has taken over on it. Even though it’s under warranty, I need a reliable car as we have a new born. Their loaners are no longer from the dealership, they sent me to a rental place which usually has crappy options as well lol

[FastMarkA]

All cars have the potential to be lemons, even the 40i and M60i.

Make sure what your dealer is doing truly is a buyback, and not just taking your 50e on "trade" so you can take something off their lot.

If it's a buyback, you should be offered the same 50e as a replacement, with no additional cost to you. If the car suits your needs best, it's worth taking another chance unless you don't view the 40i/M60i as a compromise.

No issues so far on my M60. The V8 is awesome and should be very reliable. It’s a full on M engine now. Detuned from what the full X5/X6M comp has so engine is not being strained at all.

[tooloud10]

It’s not that I’ve heard of major problems with the V8, but if the concern is that the current vehicle hasn’t been reliable, I’d choose the 40i with the B58 all day long.

BMW does not have a storied history with their V8s.

To be fair, they don't have a storied history with any of their motors. The B58, we are to believe, is the first reliable BMW motor because of Toyota's influence during its design and testing.

Outside.of.that, the only other really reliable BMW motor was the Tritech in the first gen Mini, it was designed for 3rd world trucks and could use gravel for oil in a pinch, lol.

Agree, the S68 M60i engine is derated by 15% or so from the same one on the X5 M, so given proper maintenance and no tuning, it should last a looong time.

Unless of corse that the 48V MH system fails, but that's the same with the 40i.

Any other specific M60 week points?

Have never seen anything about that, do you have a source on that?

[LDT]

Seven trouble free months and 7300 miles on my M60i.....both the 40 and 60 are fine vehicles..

I've never seen anything concrete, but a lot of talk about Toyota press releases that's said they took the B58 and made chamges to it to make sure it would meet their reliability requirements for supra. Some people even claimed it failed their testing and they made BMW go back andake changes to fix the issues.

How much of it is true vs just convenient marketing by being paired with Toyota that's known for reliability is of course, up for debate.

Okay, I looked around and wasn't able to find anything other than referencing it as a BMW designed engine. Given it was out four years before Toyota started using it I would think that may just be an urban myth.

None other than it wastes more fuel than the B58 🙂

I loved my 2021 40i and it was a joy to drive. With HP, and particularly in SUVs, once you starting getting close to 400 hp, additional HP has a diminishing return. But HP envy is real and for some, it's overpowering.

Yeah, I dunno. They certainly weren't part of the fundamentals design, but maybe they were part of some continual improvement efforts, maybe the technical update? Or maybe it's just all marketing because people associated BMW with unreliable and Toyota with reliable, so they made up some stories about it? Maybe it wasn't even marketing that did it and instead was just people on the Internet? Who knows? Time will tell how robust they are as they start to get a bit older.

It's only wasted if you don't enjoy it. If you enjoy your use of it, then it is fuel well used.

For what it’s worth I have a ‘24 M60i that’s been in the shop four times since I purchased it in July for drivetrain malfunctions. I think I’ve got a little more than 3k miles on the odometer.

That said, I would take whatever you hear or read in forums - positive or negative - with a grain of salt. The subset of owners who participate in these types of platforms are not a representative enough sample to extrapolate trends to inform or guide your own purchasing decisions. The only people with meaningful insights on your reliability outlook on a 40i or M60i are within BMW.

From my partner’s experience working for a different German luxury brand, it’s probably safe to assume - even if there are actually widespread issues that are resulting in vehicle buybacks, costly extensive warranty repairs or putting the company in significant litigious jeopardy - it’ll take up to a year to fully resolve the matter at an organization-wide level (across research and development, production, service). Your specific car’s issues may have been resolved through trial and error long before then and is essentially serving as a data source. For 2024 models, as my Service Advisor said so kindly, we’re kind of the guinea pigs. Having enough data on the engines, drivetrains, electronic hardware and software, product components, manufacturing and quality control to pinpoint non-obvious causal issues takes time. Generally speaking these cars went through extensive testing prior to release while in development, what’s going wrong (if there are widespread issues) is typically not obvious, quickly resolved or of trivial cost to their business.

I’m really fortunate to work remotely most days and to have access to our ‘23 M550i when I do need to commute to the office. I’ve basically told my Service Advisor to take however long they need with BMW to actually fix the car as opposed to trying to just rush it back to me without getting to the root cause. If they offered me a different car, I don’t know that I’d take it since mine was a BMW Individual order and frankly I’m not willing to give up on a $104k few month old car.

If you want details on my M60i issues:

My issues are reminiscent of those experienced by others since the 48v mild hybrid system rolled out a few years ago. Three of the four times drivability wasn’t affected - but one of the times while driving home the vehicle began making a pronounced high pitched noise while idling. This persisted for several minutes and then I then received the iDrive message "Check Control: Power Supply. Stop carefully. Do not continue driving. Continued driving will lead to malfunction of safety relevant functions. Battery cannot be recharged. Call Roadside Assistance." The vehicle became extremely difficult to steer and subsequently made more unusual mechanical noises.

[JoeAyalaM]

So... the 40i does not seem so slow now.
