What component or system failed or malfunctioned, and is it available for inspection upon request? The instrument cluster display intermittently failed, either showing incorrect information or going completely blank while driving. Yes, the component is still installed in the vehicle and available for inspection upon request. How was your safety or the safety of others put at risk? When the display failed, I was unable to view critical information such as vehicle speed, warning lights, and engine performance data. This posed a significant safety risk, especially while navigating traffic. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was reproduced and confirmed by a independent service center. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first ap

Component or System That Failed or Malfunctioned: The component that failed was the partial-load ventilation valve, which is part of the engine’s crankcase ventilation system. This valve is responsible for regulating airflow and pressure within the crankcase during partial engine loads. A malfunction in this valve can lead to increased engine pressure, oil leaks, and potential damage to engine components. The component is still available for inspection upon request. Safety Risk: The failure of the partial-load ventilation valve put my safety, and that of others, at risk in the following ways: •Engine stalling or reduced power while driving, especially during acceleration, which increases the risk of an accident. •In some cases, oil leakage caused by excess crankcase pressure could lead to engine compartment smoke or a potential fire hazard. •If the engine performance is compromised, it may suddenly lose power on highways or intersections, posing a serious risk.

Approximately 6 months I noticed my vehicle began to emit an odor and is not responsive immediately when I press on the gas. During this time period a yellow check engine light appeared on my dashboard. My local mechanic recommended Christopher Motors in Warwick Rhode Island and German Motors in Providence, Rhode Island, who specializes in Mercedes. I scheduled an appointment and took the vehicle to Christophers Motors to get a diagnostics check for $130. Christopher motors did a diagnostic check and revealed that the car needs a crank shift ventilator that will cost approximately $1500-$1800 and could not guarantee if the service engine light would be removed. During this time I received a Vehicle Registration Suspension notification for the State of RI for a failed safety inspection. I was extremely stressed receiving this notification as I recently purchased this vehicle, and I am being told by the State of RI my car is unsafe to drive and my transportation for work is being remov

Hello, My 2017 CLA Mercedes was recalled April 1 2021. They said its a hole in the steering shaft and it can lead to noises and crash! Its been over 3 months and the manufacturer has not fixed my car. Everytime I call they don't have an update on when it's going to be fixed. I have my family who I drive around in this car and I'm worried the steering might cause harm to us. We need assistance in getting this resolved. Thanks

The Panoramic Sunroof Glass front cover has detached three times from my 2017 CLA 250 (VIN#[XXX]). The first time that it detached was with the previous owner and was repaired at a Mercedes dealership in Tampa Florida. It has since detached twice with ME and I have only owned it for 12 months. The first time that it detached with me, I was driving approximately 60 MPH on I-85 in Montgomery. AL. It blew off and could have definitely caused a VERY SERIOUS accident, but luckily no vehicles were behind me at the time 4/29/21. So I went to the local Montgomery, AL. Mercedes dealership, Jack Ingram, and they said that there was No RECALL and there was nothing that they could do. So I had to purchase my own replacement glass from Mercedes and have an auto glass repair co. install it. Fast-forward to 6/18/21, the newly installed roof glass blew off again as I was driving down S.R. 115 in Montgomery, AL. I was going 55 at the time. This time it blew off and several cars had to swerve t
