This page covers 12 recalls and 16 owner complaints for the 2019 Mercedes-Benz E 450.
Complaints for the 2019 Mercedes-Benz E 450 are spread across a small number of reports, with the powertrain drawing the most attention. Owners describe a knocking noise under acceleration and deceleration that was traced to a failed U-joint, and at least one report describes a vehicle that became nearly unresponsive while accelerating onto a highway, accompanied by a cascade of warning lights across the instrument cluster. Electrical system complaints include intermittent warning lights tied to the stability control, steering assist, and lane-keeping systems activating together, as well as a rearview camera that stopped displaying an image when reversing. One isolated report describes a parked vehicle catching fire under the hood. With only 16 total complaints on file, no single system shows a high-volume pattern, but powertrain and electrical warnings are the most consistently mentioned themes.

By System
The 2019 Mercedes-Benz E 450 has 12 recalls, the most serious being a software defect that can stall the engine without warning and a steering rack issue on rear-wheel-drive models where the rack can fail and prevent proper steering control.
Two recalls address the seatbelt and crash restraint system: pretensioners and the pre-crash belt-tensioning system may not activate in a crash, and on coupe and cabriolet trims, the belt tensioners may similarly fail to tighten in an impact. On certain wagons, the tailgate spoiler is not properly secured and can detach at speed, becoming a hazard for other vehicles. The automatic emergency braking radar can also fail to apply braking as expected in a potential collision. Rearview camera software can produce a blank screen when reversing, reducing rear visibility. Two related recalls cover the emergency call system: one version of the defect routes a crash notification to the wrong location, while another disables the system entirely, preventing any contact with emergency services after a crash. On coupe and cabriolet trims, tires are marked with an incorrect maximum inflation pressure and may lack the strength to handle the stated pressure, raising the risk of tire failure. Vehicles that have had the instrument cluster replaced may be missing the audible and visual reminder to buckle seatbelts.
