    The car did not give any warning before this issue came about. A matter of fact when I took it to the mechanic they were unable to do a diagnostic test because there were no error messages and check engine light never came on. After taking it to the dealership they were able to check the history and saw that the error code P061b00 shows that the clutch position switch module needs to be replaced. While driving in traffic the car went into N (neutral) and wouldn’t not go back in D (drive). It took several minutes of me trying to change gears but it eventually went into P (park). The vehicle is unable to change gears sometimes and this is unsettling because the safety of myself, my children and others is affected if I’m driving and the car goes into neutral all of a sudden with no warning or goes into park and is unable to move. This occurred several times within a two week span while my children were in the car and this could have ended very differently. I took it to a certified mechanic who provided an explanation based on the error code received and stated that this was a huge safety issues that needed to be addressed.

    In April 2022, I purchased a 2018 Mercedes-Benz E300 4MATIC from CarMax in Tinley Park, Illinois. After the purchase, I discovered several unresolved issues that compromised the vehicle's safety and reliability. Key components, including the battery and alternator, were defective. Mercedes-Benz confirmed the battery had not been replaced since 2018, despite CarMax’s assurance that it was new. This defect contributed to electrical system malfunctions, affecting the vehicle’s performance. Additionally, CarMax conducted substandard repainting on the backseat. The peeling paint transferred to my clothing while driving, causing financial losses and embarrassment. Issues with the rims were also mishandled, further compromising the vehicle's quality. CarMax failed to disclose unresolved safety recalls affecting critical vehicle systems, and their inadequate repairs and omissions put my safety at risk. These defects have caused significant inconvenience, financial loss, and concerns about the vehicle’s reliability. Despite requests, CarMax has not adequately addressed these issues. CarMax acquired the vehicle in 2021 from its first owner, who had purchased it in 2018. At the time of acquisition, the vehicle had been driven 45,069 miles. When I purchased it in 2022, the odometer read 57,925 miles, indicating that CarMax operated the vehicle for 12,856 miles. This period of use was later discovered to involve its usage as a loaner vehicle, a fact not disclosed during the transaction. Upon taking possession of the vehicle, I became aware of several safety issues that were not disclosed, including unresolved recalls affecting key components of the vehicle. Despite the critical nature of these recalls, CarMax sold the vehicle without addressing these defects or informing me of their existence. Omission of Material Safety Information: CarMax failed to disclose the vehicle’s use as a loaner car and any associated wear and tear, which likely exacerbated the safety risks.

    added information: the issue is the piston, it went off due to a bad part. Mercedes Benz knew about the issue with the type of engine M247. there is a class action lawsuit pending. But I'm reporting this because i didn't know and it happened to me just a month out of warranty. Now, the dealership is asking me to pay for the labor. the dealership is House Of Imports in Buena Park. This has to do with the piston failure.

    Vehicle went into limp mode at 83,000 miles and it was due to the electronic valve body failing within the transmission. Dealership mentioned it shouldn’t happen in a vehicles lifetime, this includes maintenance at the right interval (60,000 miles), which mine was. I was quoted roughly $3,800 by the dealership but after speaking with corporate it was brought down to $2,600.

    The back-up camera failed while in the middle of reversing. Screen went completely black and unresponsive. Putting the car in Park then back to Reverse didn't work, screen still black. Tried turning off the car and turning it back on, screen still black and no back-up camera when I put the car in Reverse. I tried turning on / off the infotainment system and no change, screen still black. Later in the day when I got back in the car, the screen came up MUCH slower than usual, but did eventually come back up.

    yellow check engine light came on and a few days later the car stalled on the road potentially causing an accident. took it to a shop and it has a p052e (crankcase valve issue), then took it to mercedes and theyve confirmed that oil has been leaking and it needs a new cvp ($3000) AND oil has leaked into the engine harness ($4000) but a few other indie shops have mentioned that id probably also have to replace the thermostat because thats usually damaged as well. You can google this issue and see that its insanely common, dangerous, and a huge financial burden on mercedes owners. There should be an immediate recall.

    Recurrent crankshaft ventilation valve failures. Replaced 14 months ago and has failed again. This is a common and known issue with vehicles in E class from 2017 through 2019 and Mercedes has not issued a recall. Perhaps because it costs $3500 to replace it if out of warranty. Entire system replaced Feb 17, 2022 and has failed again (April 6th, 2023)

    While the vehicle was parked, at approximately 6:15 pm on June 11, 2022 while I was retrieving my iPod that was on the cupholder of my wife’s car, I got cut on the back of my right hand by the chrome plating lining the top part of the cupholder. The cut was painful and was one centimeter long. After I got cut I noticed that the chrome plating around the cupholder was peeling off and was sharp to the touch. The peeling off was mainly on the middle to the left-hand side of the center console cupholder, it is razor sharp and very dangerous. Please warn other drivers about this danger. It would be especially dangerous if someone gets cut while driving the car. It seems other Mercedes Benz owners have had this issue too: Here - https://mbworld.org/forums/c-class-w205/724605-interior-chrome-trim-flaking.html And here - https://mbworld.org/forums/w213-amg/810641-ashtray-cup-holder-trim.html This problem is similar to one I had experienced years ago on the door handle of a Hyundai Sonata I used to own, with peeling sharp chrome edge on interior drivers door handle - https://www.autoblog.com/amp/2009/05/26/hyundai-recalling-over-91-000-sonata-sedans-due-to-sharp-chro/
