The Problem: The company opened an investigation in early September after receiving reports of three vehicle fires, all occurring with just a few dozen miles on the odometer. In each case, the vehicles were executing parking maneuvers before igniting.
Within days engineers narrowed the likely culprit down to a power steering fluid leak. Further analysis found that the leak likely originated from an improperly placed hose clamp, which can result in complete detachment of the low-pressure return hose and a large volume leak.
Two more failures in November in China resulted in less damage, confirming hose clamp misplacement as the root cause.
The Fix: Service technicians will inspect the hose assembly and reposition the clamp if necessary to prevent failure. The campaign affects approximately 60,000 vehicles sold in the US market. Visit the National Highway Traffic Safety Administration for more info.
The Problem: The company in November received notification from its DSC hydraulic unit supplier of a possible manufacturing error. The problem is said to restrict movement of the hydraulic pistons, negatively affecting DSC performance.
“Impaired DSC functionality may negatively impact vehicle handling and braking and increase the risk of a crash,” the recall documents warn.
BMW initially believed any hydraulic problems would be identified during routine pump-circuit checks at the assembly plant, however an investigation and driving tests apparently confirmed that the defect could be present in production vehicles without prior detection.
Injuries/Deaths: “BMW has not received any reports, nor is BMW otherwise aware, of any accidents or injuries related to this issue,” the company says.
The Fix: Service technicians have been instructed to inspect the DSC hydraulic unit and replace the component if necessary. The campaign is limited to just 16 units in the US market. Visit the National Highway Traffic Safety Administration for more info.
