4 recalls across 4 model years
The Mercedes-Benz 450 has 4 recalls spanning the 1972–1977 production run, the most serious being a transmission control pressure linkage defect on 1976–1977 models where a plastic bushing can deform and prevent the throttle from returning to idle, leaving the driver unable to reduce engine power and risking loss of vehicle control.
The 1973 model year has a cruise control actuator mounted on the wheel well that can corrode to the point where the cruise control no longer responds predictably, either holding speed when the driver intends to cancel it or failing to engage. The remedy involved relocating the actuator to a less exposed position. The earliest production year, 1972, has a structural concern where welds on the left front frame members may not have been completed correctly, which could compromise the integrity of that section of the chassis.
