SEAT BELTS
Passenger seatbelt does not latch to the buckle. Therefore I am unable to have passengers in my vehicle. And when I do it becomes a huge safety issue. No mechanic can seem to figure out what is wrong with it.

SEATS, WHEELS, ELECTRICAL SYSTEM
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.

ENGINE
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.

SERVICE BRAKES
Rear brake lines have rusted out causing a safety concern. Mercedes will not extend the warranty to repair the recognized inferior parts as they did for the rear subframe. The rusty rear brake lines are related to the rusted subframe which was repaired under extended warranty by Mercedes at no cost. The same should apply to the rear brake lines. I am currently having the rear brake lines replaced due to this rust and safety issue. Please require Mercedes to extend the warranty and related repair to the rear brake lines as it is systemic to these cars.

FUEL/PROPULSION SYSTEM
Recently, I have noticed a strong gas smell emanating from the rear driver’s side of the vehicle. Upon further research, I discovered that there was an open recall affecting Mercedes E-Class vehicles of the same year for a similar issue. However,my vehicle’s VIN is not included in this recall. Given that my vehicle is experiencing the same problem described in the recall, I am concerned about the safety implications and believe this matter warrants immediate attention. I would like clarification on why my vehicle is excluded from the recall despite exhibiting the same issue. Additionally, I would like to know if I am expected to pay out of pocket for repairs related to what appears to be a manufacturing defect acknowledged by Mercedes-Benz for other vehicles of the same year and model. I kindly request that this matter be escalated for review, and I look forward to your prompt response. My goal is to ensure the safety of my vehicle without incurring unfair expenses for a known issue.

ENGINE
The vehicle is getting stuck in parking and can not shift out of park. The issue first happened at the dealership when looking into an auxillary battery issue which has since been resolved. After over 30 minutes of trying to resolved the dealer was able to get the vehicle off the lift and switch the gear back into drive. Since then two days later the batteries were replaced and the same issue happen again (stuck in park) and now I see a transmission light on as well. I am not sure if the dealership noticed this when they had the issue in the shop. There was a previous transmission recall on the vehicle, which Mercedes said was previously addressed. My concern is that this can happen while driving which would be an extreme safety risks to myself and others. I don't believe I had any gear shift repairs since I owned the vehicle and the recall for my specific VIN may have been missed or not fully addressed. As of now I am unable to operate the vehicle and would like a recall reissued to resolve the problem. Thank you in advance for your assistance.

ELECTRICAL SYSTEM, POWER TRAIN
Twice within a year a "48 voltage battery malfunction" warning appeared on my dashboard. Then a red warning light appears and I had about 30 seconds to find a safe place to pull over as loss of power causes deceleration of the vehicle . The cause, according to the diagnostic test performed by 2 different Mercedes dealerships, is that a software update is needed. A know of no situation where the machine crashes first then you're told to update its software. I am concerned that this will unexpectedly happen again and possibly on a road where pulling over to a shoulder may not be possible in the little time given before power failure.

FIRE FIRE FIRE Information light came on just saying 12 Volt Battery. I sat in the car letting it idle for about 3 minutes. It began to smoke and then burst into flames. I called 911 got the fire department here but by the time they were here there was not much left. The car essentially burned to the ground and insurance has declared it a total loss. Car was in my driveway, was certainly a danger to me, to my house and to my neighbor's cars and house.
