Was there an update from the dealer on this??
We had a similar issue with our 2016 BMW XDrive 40e Hybrid. Our son was at a stop sign, in electric mode i'm assuming since it was stopped, then he accelerated normally maybe up to 15-20mph and turned on Sport Mode. The vehicle immediately had a Drivetrain Malfunction and jolted and shuddered. He was able to get home on the Electric only. We had to have it towed to BMW and after waiting for 3 months (they ordered a new engine as they thought it was seized - we did too after researching our engines models class action lawsuit about premature engine chain guide failure) they finally pulled the engine and found major damage to the transmission and parts. The Torsional Vibration Damper was destroyed and bowed out. BMW said they had never seen anything like it before. The also had to replace the Crankshaft as well as a bunch of little connecting parts. Total was over $6000. My question is why did this happen? Was it because sport mode was pressed while driving in E-mode?? I know you can press sport mode while driving but what about on the Hybrids? Thx |

Same thing happened to me.
Brand new, less than 50 miles on odometer. First drivetrain malfunction, then a few days later: check engine. Then while headed to service, engine overheated warning on highway, car refuses to accelerate. Car limped at 10 mph, had to pull over in shoulder on busy highway way to let engine cool. After 15 mins, tried to exit highway, still overheated, then got towed. Did anyone find out cause of their issue? Hardware vs software? |

Literally just had this happen to me, on the way home. didn't get the chance to charge the battery last night, so it was near empty. Zero driving issues, however, and it came on during ICE running, a few miles from home. 9000 miles on the car, and have had zero issues with the car, though it recently did a SW update, so I'm a bit curious. I was planning on taking it on a roadtrip in three weeks from the PNW to Southern California, but I might be rethinking that plan.
Any updates on root causes? I saw the bad battery sensor issue someone posted earlier. Quote:

Sorry, which check control messages?
I brought it home, charged it for maybe 30 mins (was out of juice), then was able to find one of the local dealers with a little bit of time this afternoon. Ran it over there (was totally fine -- error cleared itself and wasn't even there when I started the car to leave). Drove completely fine, etc. Service manager used the key fob and pulled a report from it (super cool!), using a key fob scanner, and we saw the errors, but said that sometimes happens when the battery is empty. Said ok to drive, so I drove it home, and the car acted normally again, with no other errors. |

as I mentioned earlier, they are known to appear after a software update and usually clear by themselves (you likely didn't have to take it the dealer so soon). FYI, it's even mentioned in the release notes of the software update that check control messages may appear |

Because this post is a year old, he joined specifically to post about this and then left.
IMO, I just read the initial post and there was way too much drama. If the dealer says "car is safe to drive" and you attempt to drive and the car is "gasping for breath" and not driving normally....don't f***ing keep driving until it dies! Pull over while it's still safe and call for a tow. WTF. |

I took delivery of my 45e here in the UK on 1st March last week. Had only driven it twice and 120 mile in total, then get "Drivetrain Error" and "Unable to Charge Error" it was recovered to the Dealership who confirm it was a Battery "Safety Box" issue which needs replacing. only feedback being "parts ordered and should be here by the end of the month"
Dont suppose any other UK owners have had the same, any idea on realistic ETA of parts?? |

I have a 2021 X5 45e, now with about 24,000 miles. Very similar issues back at end of May: - Several days worth of "Unable to Charge" errors. In most cases I could pull the plug out, wait a second, plug back in, and charge would start - Driving to work one morning and started getting Drivetrain errors. Everything shifted to ICE, and I was able to continue driving and make it all the way to dealer shop. - Dealer took 3 days to diagnose the problem, with delays due to having to contact BMW engineering and get guidance on what to do about certain error codes (unfortunately I don't have any details on that part) - Told me they needed to replace Safety Box, and some of the associated connectors that connect it to the high voltage battery. Initial estimate (after I pushed on dealer) was 3 weeks to get the parts. At the end of the 3 weeks I pushed again, and was told it would take ANOTHER 6 weeks - 'til the middle of August. Actual delivery was middle of July - and about another day to install everything and do some test driving. I got car back from dealer on July 15 - almost 7 weeks after I first took it in. Dealer complained every time I talked to them about parts delivery from BMW and the whole litany of supply chain problems you hear about in the news these days. They said I was not only one stuck waiting for parts. I'm happy to have my car back now, but that was a long 7 weeks. Everything seems fine now - I haven't had any problems for past 2 days, and I've driven enough to go through full discharge and re-charge cycle now. I gotta say - I'm a little concerned at the number of other reports I'm seeing for similar problems with these electric drivetrain parts. It leaves me wondering if it's going to make it another year without having another similar problem. That said - I otherwise love the car. Great ride, great fuel mileage (averaging about 60 mpg over past year). Great small SUV type of car that let's me do all the things I want with it. |

Same error
Just last night at 10pm driving into the grocery store I got the first yellow message, Drivetrain Malfunction, which said I could continue driving. Then I got the red error Power Supply (stop carefully, contact roadside assistance).
I called BMW Roadside assistance which were helpful. But I'm surprised it took 2 hours for a tow truck. I am under the assumption the local BMW will accept it after hours as a drop off. Then we'll see. This is my 3rd Warranty error. First was a dead car after an OTA update. Then the battery pack recall. Now this... AFter reading the thread, I'm worried this will be weeks If that's the case, I'll be calling a lawyer and checking the Lemon Laws for Nevada (although I bought this in CA.) Not happy. cheers UPDATE: today I got a call from the BMW SA, he said they got lots of battery related codes. They are calling in a battery expert to look at this tomorrow, and he said it looks like it could the computer that controls the battery, which I guess he means the Safety Box everyone is talking about. We'll see. Last edited by leightos; 08-17-2022 at 05:39 PM.. |

Reading posts re: 2021 X5 45e Drive Train Malfunction. This too happened to me. My car has 36,000 miles. 100 degree day, after driving 5 minutes, Car begins to accelerate on own. I start braking, and upon incline up hill, car stops accelerating. I push gas and it does not accelerate. Triangle in red color appears in dash: Drive Train Malfunction. Car is not safe to drive. Pull over. Turn ignition off. Press emergency brake. Dash says air shutting down. Car completely shuts down. Windows are down. Car will not allow you to start at all. Each time you put foot on brake to start, pedal kicks back. Towed to BMW dealership. They state that it is a faulty battery. 3 days exactly after getting car back from dealer . . . 100 degree day, car display states Drive Train Malfunction. I pull over, turn car off- tow it to dealership again. It’s been there since 8/2/22 this time. BMW of America involved. Not confident at all with this situation. P.S. both times were very dangerous traffic situations, rush hour and no pull offs. Crazy! I see other posts similar and really hope this gets resolved. I drive way too much to have these breakdown issues.

My update is that they said it will take another est 4 weeks to fix. (ordering circuit boards from Germany) That's if I'm lucky. Car has been in the shop already almost 30 days in a year on various issues including repair to recalled HV battery modules. SA here said no one has seen this type of serious error from a 45e. That gives me hope, but I might swap it for a M50i if they let me. We'll see because I noticed there are NO 45e's or M50i here in Vegas, and very few in Cali. None avail w/ my high spec car. |

Drivetrain Malfunction '22 X5 45e
I too just had a drivetrain error message while in hybrid on my '22 X5 45e that I received in April and have 2,000 miles. Drove to dealership the next day. After a few days the dealer, after conferring with Germany , decided to "drop" the battery and investigate.
BMW needs to replace the high voltage accumulator wiring harness and high voltage accumulator control unit and "about 100 other small parts, nuts and bolts". Not at all what I wanted to hear, or have my new car torn apart. Will have to wait 10-15 biz days for the parts to arrive, and who know how long the replacement will take. Other annoying issue is the lack of a wireless charging pad in a $70k car. Thought it was a standard feature as this was not an option when I ordered the car. Seems due to the chip shortage earlier this year, the option was not available as it is now. I have asked BMW to add and I will pay the option fee. First world problems I know...but come on. |

I would strongly recommend calling the BMWNA Customer Service line and get them to assign a Representative to your case and follow the progress. This is a major repair, and I'm not saying your repair will go wonky, but I'd want to make sure it is fully documented w/ a set of eyes at BMWNA. They will most likely review the case, the troubleshooting and the solution. cheers.. good luck and I'll post again when my parts arrive. Last edited by leightos; 09-01-2022 at 07:26 PM.. |
