I guess I will learn more and hopefully I do not see the high voltage fault again.

I’ve had high voltage and drivetrain faults and have been charging at 32 amps with a Charge Point Home Flex.

Welcome to the forum. You can ignore what your dealer is telling you. It is just an excuse they use.

As a result, an equivalent replacement vehicle is going to cost me thousands more. This doesn't seem fair.

If I go the Lemon Law route to try and be made whole, is BMW forced to see that process out or can they just settle with me before the vehicle is declared a Lemon? In other words, is there any benefit to them in trying to make me happy now?

I am not an attorney but I suspect BMW would much rather settle this w/out declaring the car a “Lemon”. As soon as the car is tagged a lemon it’s resale value will be greatly diminished. I would be prepared to force the lemon issue and make BMW give you a better deal, it’s in their best interest.

Another X5 50e with High Voltage Battery & Drivetrain error codes. December 2023 build.

First time came up soon after taking delivery at ~300miles, was told to ignore it. Second time both codes came back @1200 miles but cleared after car restart. I still took it to dealer to get checked out. Dealer told me that these codes kicked in at least 15-20 times in the last month without CEL. They are now talking to BMWNA to figure this out . I never expected this from my first BMW, questioning now the decision to move from Japanese cars!

Was someone given this response that the code kicked in the background at least 15-20 times without throwing CEL or Wrench sign? It looks not possible to me.

Dealer informed me they are replacing the SME when it comes in tomorrow and hope to have it by the end of the week but I will believe it when I actually see it.

What I find odd is are they saying the car wants 6 amps(user setting) so when I feed it 32 amps it is not happy?? I can say and others will have had same experience, since the upgrade to 240V and the corresponding BMW connector, charge time is about 3-4 hrs compared to the 20 with the 120V. Simply not understanding the error code and the explanation. I pick it up tomorrow so maybe I will get some clarification.

I’m curious…for the folks with the check engine issues, what kind of charger are you using? It shouldn’t make a difference, but does it? I use a Tesla Gen 3, no issues to date. Nov build.

I’m using a Pulsar Wallbox. I hope BMW doesn’t start blaming these issues on the chargers so they can pass the buck.

If all they did was move that slider up to 32A, then I suspect you'll be back in a few weeks with another High Voltage/Drivetrain error.

I don't think BMW will but we have had a few dealers try and blame it on the charger. Obviously it isn't the charger causing the problem but dealers will say anything at times to get out of trying to track down an issue. Which in this case they likely will not be able to do anyways.

I can confirm that they have...

At one point, my dealer blamed my multiple CELs on my Juicebox 40, stating “the charger isn’t responding to the car when it wants to slow the charge speed as the battery approaches full”.

There wasn’t much substance to their response when I asked them to specifically explain this phenomenon or how one might be expected to be able to charge at a random charger if only certain types of chargers “responded” to the car.

They didn’t have any answers. It’s misdirection while they rebuild modules and update software/parts.

My replacement 50e will be arriving later this summer via a trade assist after 7 visits to the shop.

It’s not the charger. I know because I swapped my Juicebox for a ChargePoint and still had plenty of funky issues.

Kind of what I was thinking.

I don't see why te car would throw a fault by reducing the charging speed. Sounds like the usual BS from the dealers.

It doesn't. I've had the same charger (Emporia) on two different 50e's. The first one went back to BMW, many faults, the second one so far flawless.

[kmell822]

Ok car is back. invoice say: "Checked fault memory and found fc 031b93 load charging error, 224581 AC charging not available, performed test plan of stored faults, found faults not present at this time. Verified correct charging of vehicle with shop charger for high voltage system. Checked and adjusted vehicle charging settings to recommended settings, no cause could be determined at this time. Possible customer charger or infrastructure caused fault. Vehicle operation checks ok at this time."

I use the supplied BMW charger running off of a 240 volt outlet. They did not say anything when I picked up the car. They handed me the paperwork/keys and that was it. I found that a bit unusual. We will see if the error code comes back. Thx for the various comments.

[DXS]

The actual chargers are in the car. The wall unit everyone calls a charger has very limited operation. Basically it communicates with the car to tell it when the connection to the car is active and what the maximum current is that it can supply. Once all is good, the car sends a signal back to the wall unit to close heavy duty contacts (contactor) to allow power to flow from house to car. The car itself controls the amperage/charge rate (in most cars you can modify this in one of the menus). See this video:

So generally the wall unit does not modify the 240 volt AC power to the car. It basically just turns power on and off after ensuring all conditions are met for safe charging.

If the BMW service guys are blaming a CEL on the wall unit, unless the wall unit just fails by refusing to turn on 240VAC, then I'd be disinclined to believe them.

What are the four Check Control messages?

[leightos]

just fyi, I had a 2021 45e that failed with drivetrain malfunction and BMWNA bought it back.

Now I have a 2024 XM (also a hybrid) that has thrown the CEL 3 times now in the first 3 weeks of ownership and BMWNA is now involved again. I know this is wrong forum, but that CEL related to an expansion valve for the battery AC system seems to be similar for both the 50e and the XM. Just following along here as well.

TurtleBoy has always been a great help.

I didn’t realize that the XM shares the same battery pack. Ouch! That is an expensive ride for this problem.

yes, it's a big money hit. As for the battery pack, it seems the battery capacity on the XM most closely follows the 45e, as it's a 30 mile range. I know there are technical specs here I can ref related to battery modules, but I'm lazy this Sunday morning to find and print. But I am seeing similarities in the cause of the repeated CELs (expansion valves for battery AC sys). I think BMWNA knows this , and I am guessing if someone does get a lawyer and goes to court, BMWNA will have to produce documents about how pervasive this is - in other words, they would have to reveal what they knew and when they knew it. Could be damaging to them. Just pure speculation at this point. But I am getting a little angry now, 2 out of 3 hybrids I purchased (not leased) are faulty.
