That sounds like our experience. We take it in (while under warranty) making the sound and they say it's fine, then after it's out of warranty and the sound appears louder they say it needs the $14k replacement.

$4k was the estimate I received over email from QC Charge, after checking the speed sensor and there isn't a leak we have decided to just drive it until the rebuild becomes mandatory.

How is your car now? I'm assuming the whirring noise is completely gone now? Congrats on getting the work done.

I heard the whining getting slightly louder over a few months. At the beginning I took the car to the local dealer for servicing, and after $1k they said all is well. Over the next few months the sound got more noticeable, and when I took it back they said it would cost $14k to replace the drive unit. All this while asking if I wanted the $800 serv8ce which is coming up in a few months.

I shipped the car from Florida to QC Charge in California to have the bearing replaced. $4k was the bill. The bearing kit sells for $400, but the labor is the kicker. I may have attempted the repair, but for that bill I felt better off having them do it.

If your B250e suffered the coolant leak issue in the US, please consider filing a report with the National Highway Traffic Safety Administration. They have the authority to force MB to recall and repair the issue. https://www.nhtsa.gov/report-a-safety-problem#vehicle

Thanks for the reminder, I'd also suggest everyone else with this issue due the same.

I've PM'd around 20 people from this forum who have suffered the travails of a failed drive unit, and asked them to reach out to me if they would like to add their voice as we collectively approach MB, or litigation, if necessary, to try to get MB to address this safety and cost issue. I am also taking the same approach on Facebook. If you have suffered a failed drive unit, even if you no longer have the car, please PM me and tell me your story. We are infinitely stronger as a group.

If your b250e was repaired under warranty or at your expense, please consider reporting the original issue to NHTSA.

MERCEDES WILL BE FORCED TO REIMBURSE THOSE WHO HAD TO PAY FOR THE REPAIR in the event of a recall.

This has happened too often for NHTSA to ignore, but they will only act if everyone who had the coolant issue/catastrophic failure actually reports it.

ALL CAPS. That always gets attention.

Seriously though, I enjoyed my time with the B. Sad to see a few of us have motor issues but by and large we know the majority of B250e's that were sold were trouble free (like mine). Long story but I went from ordering a Tesla Model Y, hating that experience that included a Y that arrived with a hood that wouldn't close. I ended up with a Lexus UX250h because I didn't want to deal with a 50% less range in winter, and the rest of the car's quality actually mattered to me (I'm looking at YOU Elon). Let's face it: Good effort, Mercedes but we all know the B250e was a compliance car from the beginning,. By today's standards, it's an extinct dinosaur. But hey, who doesn't like dinosaurs? The new Jurassic Park movie is proof.
