I have a 2002 ML320, the radio is out and the hole clamp used to secure the power steering fluid does not provide sufficient clamping causing a leak, esp/bas stays on causing low traction and the door lock. These items were recalled on the M-class 320, what happened to thes recalls.

My 2002 ML320 cluster display lights on my dash all light up, the check engine light comes on, the speedometer stops working actually goes to zero. Once the car comes to a complete stop it accelerates very slowly and will not shift out of first gear. This is very frightening for someone in traffic and this happens without warning. Please investigate this issue before someone is rear ended and dies.

I was driving at 40-45 mph when I noticed an orange glow under the passenger side mirror. Within a few seconds the light turned yellow, and suddenly I noticed flames are shooting out of the side mirror along with thick black smoke. I immediately turned into a gas station and put off the fire with water hose. I was afraid of the fire to get inside the car.

Vehicle's drive authorization system fails to recognize key resulting in a 'start error' displaying on dash and vehicle will not start. This item can only be replaced by the dealer and is a known defect by Mercedes Benz. The dash control unit is part # A163 545 28 32 and is replaced by a modified version A163 545 07 06. Mercedes requires owners to bear full financial responsibility for this repair, even though it is a known defect which can result in stalls and no start situation, potentially putting the driver and passengers in danger. The cost of this repair is approx. $800 to $1000. A technical service bulletin was issued by Mercedes Benz and that bulletin is T-B-80.57/32 and was issued on February 7, 2005. It covers all M class models from 2000 to 2005 model year.

  • 22,000 miles
The contact owns a 2002 Mercedes Benz ML320. While driving 25 mph, the instrument panel lights illuminated without warning. As a result, the brake pedal extended to the floor when depressed. The dealer stated that a blown fuse caused the failure and they made the replacement. The failure recurred approximately one week later. The dealer stated that there was another blown fuse and made the replacement again. The contact stated that the dealer has inspected the vehicle approximately 27 times for the same failure, but they have been unable to diagnose the cause of the failure. As of August 4, 2008, the dealer had not repaired the vehicle. The failure mileage was 22,000 and current mileage was 56,000.

  • 20,500 miles
The contact owns a 2002 Mercedes Benz ML320. A month after purchasing the vehicle, the contact experienced dashboard failure. The hazard lights began flashing on and off. She took the vehicle to the dealer and they discovered a defect in the electrical component. They replaced a fuse, which corrected the failure for approximately a month, but the failure eventually recurred. When all of the lights illuminated again, they remained lit and locked the gears. The vehicle was unable to be driven and even stalled while driving 10 mph. The contact has taken the vehicle back to the dealer at least once per month and they replaced the fuse each time, or attempted to reprogram the system; however, the remedy was never permanent. The VIN was unknown. The failure mileage was 20,500 and current mileage was 56,000.

Numerous problems with exterior and interior lighting. Most importantly the left turn signal continually goes out without notice. Sometime the interior left turn lights up and sometimes it doesn't. other times the interior left turn light goes completely out placing me and my children in great danger. Also I made a left turn and the steering went out just as I entered the beltway and was unable steer the vehicle.

This vehicle has numerous defects, and has been in for service countless amounts of times. Mb promised to replace the vehicle if their factory representative could verify my complaints. They absolutely found numerous, redundant defects and now only want to fix the vehicle, rather that replace the vehicle. What a bunch of liars. The vehicle has issues with the steering system, the wheel rubs and the power steering fades out, the radio and cd changer malfunction constantly, fumes from the ventilation system, and when you hit a bump, the car almost goes out of control, even the esp light comes on.
