Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“After about 1-2 mikes of driving my 2017 mb E300 started jerking and engine light came on when I drove toward the first lane for a left turn on a busy highway intersection. I also found the gear was changed to neutral. I tried to change the gear to drive while waiting for the traffic light but I couldn't. I stopped the engine to restart but couldn't restart at all. I pressed the mb roadside assistance button. They said a tow truck would be there within 20 mins. In the meantime someone helped push the car to move it to the side but the gear didn't stay on neutral. It kept going back to park. …”
NHTSA complaint #11111487, filed 2018-07, 17,000 miles“While in motion, engine starts vibrating and the check engine light comes up. Took it to the mechanic and its a broken piston. This is the third time this is happening on the same engine”

Recall date- 2017-02-07 Recall no. 17V078000”
NHTSA complaint #11732941, filed 2026-04“PCV regulator valve failure at69,000 miles on my 2017 Mercedes E300.. I understand this is common before 100,000 miles with the four cylinder turbo, I feel there should be a recall and be replace at Mercedes dealers cost. (to replace cost is around $2,000 about 7 hours labor I was told)”
NHTSA complaint #11628826, filed 2024-12“Having a Mercedes was my dream since I was a kid and I’m completely heartbroken to have to file this complaint. I’ve been working literally my whole life to finally be able to afford my 2017 E300. I purchased it from Autobahn Motors in Belmont, California in August 2020. My car has ~48,000 miles on it and I still own approximately $14,000 on the car as of today (5/20/2023). When I was driving on the highway my car engine light came on, started to violently shake, and I thought it was going to stall out. …”
