While traveling at highway speeds with adaptive cruise control safety systems engaged, the vehicle failed to detect a hazard immediately ahead in its lane. The Forward Collision Warning failed to alert the driver, and the Automatic Emergency Braking (AEB) failed to initiate automated emergency deceleration. Manual emergency braking was attempted by the driver in the final milliseconds, but the vehicle's braking system failed to sufficiently decelerate the vehicle, resulting in a high-energy frontal collision. Despite severe structural deformation concentrated entirely on the front fascia and crumple zones, the Supplemental Restraint System (SRS) completely failed and no airbags deployed. The driver sustained injuries to the neck, back, and ribs. The vehicle has been declared a total loss by insurance and is available for inspection at a salvage facility. The manufacturer was notified over a month ago (Case #21986205) but has failed to pull the Event Data Recorder (EDR) telemetry or provide an engineering review timeline. No prior warning lamps or system malfunction messages were present before the incident.

What 2019 Mercedes-Benz E 450 owners say
Most recent owner complaints, unedited.
Backgroud: Recall #26V216 recalls classes of Mercedes vehicles for U-Joint failures. My vehicle - 2019 E460 4Matic Wagon is included in this class under the notice (Vehicle #6 [XXX] ) Issue: I took my vehicle to the dealer on Monday, 5/11 because of a hard knocking sound when I de/accelerate. Dealer inspected and noted that my Ujoint has failed. The estimate is $8100 for repairs. MB and dealer have both indicated that my VIN is not covered by the recall but have not explained why. My car is currently unsafe to drive and therefore non-operational. I have not approved repairs because of the substantial cost and resolution of whether covered by Recall warranty. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I parked the vehicle in a parking lot. I walked away and it immediately started smoking. Shortly after that, flames appeared coming from the hood. Shortly after that, the entire vehicle was engulfed in flames.
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 the federal safety agency initiate a review of the E-Class E450A systems involved in driver assistance, electrical integration, and potential remote immobilization tied to finance enforcement.
The contact owns a 2019 Mercedes-Benz E450. The contact stated that while reversing, the rearview camera failed to display an image of the rear of the vehicle, compromising the back over prevention system. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the rearview camera display. The vehicle was repaired. After investigating the failure, the contact related the failure to the federal safety agency Campaign Number: 22V232000 (Back Over Prevention), but the VIN was not included. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 10,300.
Rear camera door doesn't open to allow camera to work
My tempered glass sunroof exploded while driving at 70 MPH on a clear, sunny, 86 degree afternoon sending the glass shards throughout the interior of the car. No warning or damage to the vehicle roof preceded the explosion. There was a very loud noise followed by the safety glass raining down on myself and my wife. It occurred while driving on the expressway and no other vehicles were involved. There are only glass fragments for inspection and I will take it to the dealer in the morning. I have pictures of the aftermath if requested.
The driver and passenger seat belts do not retract at all.
The car will apply electronic parking brake when put into park. If the brake is wet due to rain and the car sits overnight or for 12 hours or more, the brake sticks to the rotor. The brake will not release unless you press down on the accelerator creating a safety hazard as the car will jerk forward or in reverse. I've raised this with the MB dealer and service technician and they confirm the this Amy happen and that there is no fix. This situation creates a serious hazard.
