Owner report 11558119 · 2023-12-02 (December 2, 2023)
My 2023 Mercedes 450E car was purchased on June 11, 2023 and has 1,750 miles. On 2 to 3 different occasions, I was stopped at a light waiting to make a left turn, fortunately my light was red and not a green permitting turning, which would have meant I would have pulled up and into the cross section to prepare to turn; I pushed the gas in the drive position and large red malfunction letters displayed across the dashboard and the car just revved. I put it in park and then drive postion a few times and had the same result. Finally, I turned the c…

Owner report 11592511 · 2024-06-04 (June 4, 2024)
This has happened once before and I reported it then. This time I was stopped at a stop light and when I pressed the accelerator to go when the light turned green, the engine was off and would not go. The screen only said "malfunction" and no error codes (as before). I pressed the start button to turn the car off and then restarted it. It was fine after that. I have left a message with my service agent at my Mercedes dealership. I had previously told them that this had happened before. I am concerned about the safety of a car the stalls like t…

I was unable to maneuver the vehicle off the road, creating a…

I purchased an E450 Mercedes before reaching my first service appointment while driving my two daughters home from school the car began to shake uncontrollably, lost power, and then the engine light and oil lights came on. The car was towed to the manufacturer dealership for repair. It was determined that the piston number four was broken and the engine needed to be completely replaced. Less than two months after having the entire engine replaced the car broke down again with a similar shaking. This time one of my children and their friend were…

Owner report 11614216 · 2024-09-12 (September 12, 2024)
The fuel pump on my vehicle failed multiple times, including coming off start / stop at traffic lights, as well as when being started. When at a stop light turning from red to green, my car did not respond, putting me in danger of being hit from behind. The vehicle is being repaired under warranty at a manufacturer dealership. It appears this is a known issue under NHTSA recall 23V445000, although my vehicle is not currently included in the recall after a VIN search of the NHTSA check for recalls page. My vehicle exhibited the same signs as…

Owner report 11628074 · 2024-11-30 (November 30, 2024)
While driving, malfunction warning flashed on dash, followed by 48v malfunction warning, then engine coolant overheat warning. The car then went into limp mode and finally stopped completely. Luckily this occurred on a residential street and not on a high speed freeway - the car gave very little warning before drastically reduced speed and shutting down systems. A 48 volt battery problem should have a redundant system to prevent the engine from overheating and not shutting down the vehicle at speed. Very dangerous!
