I absolutely love my 2016 E400, it rides super and the comfort features are over the top.

I haven't faced issues with my car so far, while the minor issues I had were serviced under warranty (over 40-60MPH a whistling noise could be heard from the front, it turns out the front grille needed foam padding between the grille and the post. One other issue was with Bluetooth music connection, which was sorted out with a firmware update).

Given you have mentioned 2014, it is out of factory warranty (4yrs or 50,000 Miles whichever is earlier) unless the previous guy purchased an extended warranty. I am sure you will have it thoroughly inspected before putting your money down.

Do post more info or pictures of the car, I am sure others will be able to give you suggestions based on the info.

Good Luck!

 

Thank you Mjain.
It's good to know that no major issues have arisen with your car.
Dealership offers a limited 90 days warranty but otherwise is out of manufacturer's warranty.
According to dealership car has been driven 22,000 kilometers (14,000 miles) so should be in good shape.

Additional info:

• It's the RWD version
• 330 HP v6 biturbo gasoline engine.

I haven't seen it personally but I'm planning to go very soon, I have done some research online and haven't found big issues with this model so your feedback reinforces this theory.

Thank you

 

Pay attention to how it accelerates with partial throttle through 2nd 3rd and 4th. My car has pretty bad torque converter shudder and I've been told I'm not the only one on this car. It makes the acceleration feel lumpy, almost like a misfire.

 

^ That could be down to the electronic transmission "hunting" between which gear it should be using. If it's okay when you try pushing the pedal through the floor, it's probably okay. Also, I would recommend trying the car up a steep hill.

 

In my case it's a shuddering issue, not a hunting issue. Like I said, there are reported issues on some of these transmissions with the E400's. Even though the same trans is used in the E350, the engine differences create different behavior with the torque converter.

 

The torque converter on my R350 has started to "shudder", the transmission shop says it's down to mileage and fair wear and tear (210K miles). If new E400s are suffering from it, however, it may be that they've over-estimated the torque capacity of the 350's torque converter and not rated it for the extra torque from the 400. BTW the E400 is really a turbocharged 3-liter producing 354 ft.lb of torque, whereas the E350 is a real non-turbocharged 3.5 liter but produces only 273 ft.lb. The give or take 25% increase in torque might be the problem if they haven't uprated the torque converter to match.

 

You nailed it exactly and that is what the transmission specialist told me. Don't get me wrong, I love having the 400. It is a completely different animal than the 350 and when you put the pedal down, it is a blast. I just wish I didn't happen to get one with this issue. I bought it with 39k but I was one month out of the 4 years of warranty. So I am still within mileage but not time; my car now has 45k on it. I've had it to the dealer once and they gave me a line about "normal operation" regarding torque converter lockup and said they didn't have anything else on the lot to compare to. A 2016 car that had a build sheet totaling almost $80 grand should not have lumpy, jerky acceleration under normal driving behavior. I am hoping that enough E400's are affected that eventually MB will issue a fix.

 

Thank you for such good information. Im crossing fingers I dont get ome with the issue.

How has your experience been with the car?
