RepairPal has identified the most common problems with the 2009 Mercedes-Benz ML320 BLUETEC based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The supplemental restraint system (SRS)/airbag light may illuminate due to damaged wires in the steering column. Any damaged wires should to be repaired and protected as necessary from further damage.
The transmission drive selector module may fail resulting in the loss of gear selection capability. This condition can leave the vehicle stranded, and will require replacement of the drive selector module.
The rear bulb warning message may be displayed even if the rear bulbs appear to be functioning correctly. This can be caused by a poor connection between the bulb housing and the socket. Our technicians recommend to "hard wire" the socket to the housing, eliminating the contacts as an issue.
