    Motor whining, needs replacement

    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...

    B250e shaking in drive

    Any progress on this? I'm guessing you need a new motor. Mine was doing the same thing, and is now in shop. They are saying new drive unit at a cost of $21k.

    Another Bad Motor-Class Action

    Here we go again. I have two 2014 BEDs. In 2017 both of them had the drive motors replaced under warranty due to the whining problem, at around 18K miles. Now one of those is getting a "Without starting return to workshop" error, and is a bit jerky when driving. Dealership says it is the...

    Dangerous Brake Failure

    I also get the lurching sometimes immediately after stopping. Shop said this was normal behavior. Yeah, normal maybe, but still ain't right. When the braking has failed, it has been on smooth dry surface. I've had this car in the shop for non-scheduled maintenance 13 times since I bought it...

    Dangerous Brake Failure

    Hi all, I wanted to check to see if anyone has experienced a brake issue I occasionally have in my 2014 BED. A couple of years ago, I was exiting the highway, foot lightly on brake, car in regen braking mode. All of a sudden, the car went into the thrust mode (arrow indicating charge direction...

    Motor whining, needs replacement

    We have two 2014 BEDs. As mentioned above, one of them suffered from a buzzy motor, which was replaced. Update to the story is that not long after that, the other BED started to make the same buzzing noise, which got louder over time. After a month at MB, that car has now come home with a new...

    Motor whining, needs replacement

    They had mine for pretty close to 4 months to replace to the motor for the milling noise. Just got it back a couple weeks ago, and it is *so* quiet. Also had a problem with the center console USB charger not having any power. They ended up having to replace the entire COMAND unit. All in...

    Motor whining, needs replacement

    One of my 2014's went in with a whiny noise. Similar to others, it is first noticeable accelerating through about 20 mph, especially next to a wall or parked cars. It gets louder over time. The sound is more grating on your hearing than the usual high pitch motor whine; hard to describe...

    Without restarting, consult workshop

    My car just came out after a week and a half in the shop for a 12V battery issue. I got the visit workshop-do not drive message, except that it had a picture of the 12V battery. In the manual, it says for that icon, do not drive the car, and do not tow the car. I guess one is supposed to just...

    Brake Issue

    Well, they were unable to duplicate the issue, but MB did instruct the tech to do a software update to the regenerative braking module. So far, so good. It will also be interesting to see whether this update fixes the ever-present secondary jerk after stopping.

    Brake Issue

    2014 with 8K. They have a couple of fault codes, but they are not specific. They're test driving for a couple days.

    Brake Issue

    Last week, when coming off the highway, the regen indicator suddenly went from recharging to zero, and the regen braking stopped. I quickly hit the brake, and it was rock hard, and had almost no braking action. Two or three seconds later, regen and braking starting working normally. Thought...

    Malfunction Visit Workshop

    Our B-ED gave us this week both the "Malfunction-Visit Workshop" error and the "Do Not Shift-Visit Workshop" error. Took it in to MB; all software was up to date. They did a calibration of the Parking Paw, per instructions from MB. So far, seems to have solved the issue.

    Oil leak?

    The official entry was: "During inspection, found oil leaking from transmission at left and right front axle half radial seals. Replace left and right radial seals. Correct oil level on trans 780."

    Oil leak?

    It sounds like they only replaced seals. Was supposed to be done today, but now they've moved on to several software updates. Having a repair like this so early doesn't auger well for the the longer life of the car.

    Oil leak?

    Yep, one thing I never thought I would see with an electric car. My BED with only 6,000 miles was in for its annual battery certification. The technician noted oil leaking from around the axle shaft seals. I do not have the car back yet, so not sure exactly what is being replaced, but...

    Unlocking In-motion functions

    I installed the DVDinMotion unlock over the weekend. It worked beautifully. It's pricey at $200, but it unlocks all in-motion functions that are normally blocked when the car is in motion (DVD playback, map editing, reading texts, etc). Mine is a 2014, with the multi-media package. It is...

    Check if RECALL applies to your MBe

    The recall is not public, and has not officially started yet. I would try calling your dealership service department, giving them your VIN, and asking whether there are any campaigns that show up under that VIN. If they say no, you'll just have to wait until they push it out publicly late...

    Thump! Complete Loss of Power on Freeway. Went into Neutral
