Powertrain Malfunction/Reduced Power

[4Bentley]

This is the third time I received this warning. After 2 days the warning goes away. The most recent is a few days after receiving the HVBJB service. Should I be concerned, and would the dealership be able to diagnose anything if the error is not there?

Hi there! Would you send us a private message with your VIN and dealership name and location? I’d like to look into this concern on my end.

Did you receive my VIN number? If not please provide additional instructions on how to send it.

I am experiencing this exact same situation. No issues for two years. Took in for HVBJB recall and now getting the warning. Pulled the codes and it says stalled transmission fluid pump. So, I am guessing dealer missed some steps during the recall.

Do you still have the warning? Mine goes away after a day or two. I am wondering if the codes are still there to diagnose something. I can't get a straight answer. Would I waste my time taking it to the dealer if the fault no longer exists?

The transmission fluid pump is a separate issue from the HVBJB. There have been a number of these reported. It should be repaired under warranty. Your car is likely limited to <88 mph. ??

Yep understood. I was just giving the background because prior to having the HVBJB replaced my car never had a single warning in 2 years and suddenly I get the same issue as others on here are reporting - i.e. the fluid pump.

On this post, someone suggests there are steps they didn't do after replacing the HVBJB. ?‍

It goes away after I leave the car off for a while but always reappears about 30 seconds into driving again. I've now had to borrow a friend's Tesla because I'm too scared to drive my MachE until the dealer can fit me in to have it looked at. I heard it can badly damage the transmission if you drive with this warning (and specifically the code which says it's a stalled transmission fluid pump).

Yes, @Mach-Lee ran the codes on that car. One relates to the cooling system not having been purged correctly after the battery pack was reinstalled (cooling fans) and the other is the transmission fluid pump which is not normally associated with the HVBJB replacement. ??
