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.

Complaint Repeat workshop visit for vehicle vibration while braking from 60MPH. NOTE: Although the symptom is similar to a tire or wheel vibration, it is usually readily noticeable that it is distinctly different if it happens at all times or only while braking. Cause Although the cause of the vibration is most likely due to excessive lateral runout on the rotor or hub/wheel bearing, the system as a whole needs to be checked for other possible contributors. 1. Prior collision damage. 2. Excessive vehicle sitting times without rotating components. 3. Wheel bearing/hub lateral runout. 4. Wheel mating interface has been overtightened (did not follow WIS torque procedures). 5. Mating interfaces have been excessively modified (painted, gouged, bent, etc...).
