Motor whining, needs replacement

[IKcedar]

I took my 2015 B Class into the dealer to have it looked at because of a whining noise when I accelerate. They just notified me that they will be replacing the electric motor drive unit. My warranty on the car is up in another month and does anyone know what the warranty is on the new electric drive unit is?

I had mine replaced under warranty at 47k miles in July'18. MB would never answer that question for me as I was about to have no warranty on the vehicle. They basically said I have the remainder of the 4yr/50k. The also wouldn't sell us an extended warranty as we weren't the original owner. MB had the car for 10 weeks, as we had 3 GLC loaners over that period. Since getting the car back we've put 10k miles on it and it has been performing great. We are hoping it lasts long enough to get a Tesla Model Y when they become available. Good luck, and please post an answer if MB answers

I just got the punch to the gut that I need a new motor. $11,000 !!?? After a few days of the whining noise I took the car in and found it is out of warranty and no help from MB on warranty.

I am extremely disappointed and considering just scrapping the car once it fails. There should be some sort of help given the vehicle only has 40,000 miles on it.

I'm scheduled to have the car in an EV car show this Saturday and will highlight the fact that the total cost of ownership is much higher per mile than an IC engine! 28¢/mile just for reserve maintenance. If I add in the reserve maintenance for the battery it gets more ridiculous.

If the vehicle only has 40,000 miles on it, it should still in warranty.

What is your invoice said? Is it the same "01 242-340-42-01-80 REMAN ELECTRIC DRIVE" ?

Thanks

SolarDell,

This is bad news. This is a real risk with our cars, both the motor and less often the battery. Anyone buying a used car outside the original warranty period of 4 years is at risk. The battery has a longer term but there is a stipulation that there must be an annual battery check by MB. As yours is a 2014, clearly not covered for motor even if you bought the standard extended warranty which excludes the motor and battery.

When I was contemplating buying my leased 2017 off the lease next year, this risk factored into my purchase price calculation. If what happens to you happened to me, I would consider the car totaled for insurance purposes and try to recover under my auto insurance as a total loss and take anything not covered as a casualty loss for 2019 taxes.

Very sorry to hear.

This board saved my ass! My 2016 B250e has 35k miles and sure enough I tested it and heard that whine sound upon accelerating . Took it to Benz of Las Vegas today and needed a replacement. My Warranty Expires next month. Talk about luck! I agree Benz Dealership needs to look out for this issue. Funny, when I got the car used I took it to Benz and they said all was ok last year! Haha,

FUCCP,

Hm, interesting initials but I digress. YES, you are a lucky man. Be sure to get a one-year warranty on the refurbished motor they are putting into your beloved B250e. Study the posts to get all of what you deserve.

Enjoy the ride!

Resurrecting this as I am considering getting a 2017 B250e - out of warranty and not Certified.

Data points from this thread seem to point to 2014-2016 cars having issues w/ defective motor, are the 2017s safe from this perspective? Hate to buy a $16K car to have to plunk $10K for a new motor!

hyap463,

First, welcome to the forum. It was a fun car for 6 years, first a 2014, then a 2017.

Second, don't know where you are but $16k sounds negotiable to me. Be sure to have the car checked out by a MB dealer before you buy to see if all required service was done and to let you know how much degradation of the battery pack has occurred. I miss the car.

Just leased a GLC300 to bridge to a future MB EV. Almost bite on a 2021 GLC350e last year but couldn't pull the trigger during covid when I wasn't driving much. The EQC is not sold in the US or I would be driving that. Yeah, the Burmeister is nice. I listened today for my 3 hour drive by myself. Very nice indeed.
