I was driving about 30 mph and getting on to the highway. Once I got on a beep came on from the car and every single warning light came on the car. Check engine all warnings including emergency brake collision warning the list goes on and on. I immediately got off the highway and once I got to a complete stop the car was barely accelerating. I wasn’t able to shift gears from drive I was stuck in drive. Couldn’t park the car reverse or anything. I had to turn the car off. The car didn’t turn on and then after 5 minutes it turned back on. This is 1 week after me receiving the car back for the same issue. This was the 2nd occurrence of this and when I dropped it off at the dealer they had it for 2 weeks and they “fixed” the issue. There is obviously something wrong with the car and has several problems.

The primary failure involved the electrical system and speed control, which posed a significant safety risk to myself and other drivers. The issue first presented itself when I noticed intermittent warning lights and error messages flashing on the dashboard, including indicators for the electronic stability program (ESP), steering assist, and lane tracking features. These malfunctions created erratic driving conditions, including unexpected acceleration delays and inconsistent cruise control behavior. Approximately one week before the vehicle was repossessed, I reported the issue to the dealership and requested inspection. However, I was not provided a definitive diagnosis or service record confirming evaluation or remediation. The vehicle was subsequently remotely disabled without proper notice or opportunity to repair, placing me at risk by stranding me in an unsafe location without functional transportation. This vehicle may have also been equipped with over-the-air control features or aftermarket immobilizers unknown to me at the time of financing. To date, I have not been able to inspect the system because the vehicle was taken from my possession under a disputed contract. I believe the problem has not been properly addressed or documented by Mercedes-Benz, and the vehicle is not currently available for inspection as it remains in the control of the finance company. Prior to this incident, no physical warning lamps were persistent, though the vehicle intermittently displayed electronic system errors, especially during startup or inclement weather. This complaint is being submitted due to serious concerns about vehicle safety, electronic control vulnerabilities, and potential manufacturer negligence. I request that NHTSA initiate a review of the E-Class E450A systems involved in driver assistance, electrical integration, and potential remote immobilization tied to finance enforcement.

Central digital driver cluster and lighting behind all speedo/tachometer randomly turns off while driving unexpectedly then fades back on. - can not see control indicators for adaptive cruise control when display fades out - can not see what gear the transmission is in when display fades out - at night can not see speedo, tach, or any items on the display when it fades out Dealership said they could not duplicate and didn't want to replace the cluster, because they have to send the part back to mercedes engineering and if the part wasn't faulty, the dealership would have to absorb the cost of repair. This happens every time I drive the car. Contacted Mercedes USA customer service and they have not been responsive.
