What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
On the date of purchase, while driving approximately 50 mph, the vehicleâs hood opened unexpectedly, obstructing my visibility and causing the vehicle to leave the roadway and enter a ditch. State Police responded, and the vehicle was towed immediately. This incident presents a serious safety defect.
CRITICAL SAFETY DEFECT: Recurring automated ADAS sensor failure causing maximum-force phantom braking without warning or driver input. VEHICLE IDENTIFICATION: 2023 Mercedes-Benz EQS 450 4MATIC SUV (VIN: [XXX]). CHRONOLOGY OF LATEST INCIDENT: On Wednesday, XXX, at approximately 7:20 a.m.
When the screen is blank the rearview backup camera is unavailable. Selecting reverse produces no image at all. The rear camera image appears only on that center screen, so the failure removes the rear visibility required by FMVSS 111 and leaves the driver reversing with no camera view in parking garages, driveways…
Odometer Fraud. The contact leased a 2023 Mercedes-Benz EQS 450 X4. The vehicle was a dealer sale. After returning the lease vehicle to the dealer, he was informed the odometer closure was not available during the drop-off and it would be emailed.
Several times, the car's "panic braking" has randomly slammed the brakes and tightened the seat belt. After the first few times, I took it to Mercedes and they re-uploaded software which was hard for them for some reason. It fixed the problem. Luckily, I had always been on small streets.
The charging connector overheated and thermally fused (welded) to the vehicle's high-voltage charging inlet. The connector could not be released by the vehicle or the station. A technician dispatched by the charging network was unable to remove the connector using standard release protocols.
My panoramic sunroof shattered with no warning and no apparent impact. It exploded outward, while traveling at a high speed on the highway. It was late and there were no other vehicles on the road at the time. I was not near an overpass.
