The Problem: The bolts that secure the variable camshaft timing adjustment unit could become loose and may break. This could cause reduced engine power or the engine could stall, increasing the risk of a crash. BMW has not received any reports of accidents or injuries related to this issue, the automaker said in a statement.
The Fix: Dealers will inspect and replace the affected bolts for free.
