The car brakes suddenly by itself just after the ESB/ABS lights come on along with an exclamation point (!). This has happened randomly at least 4 times since we purchased the car. Once at high speeds on the highway. It appears this problem is common with other owners of Mercedes 2001-2002 ML's. According to the forums below, the problem seems to be a "YAW RATE SENSOR" malfunction or defect. My Mercedes mechanic saw no error codes for this component and it seem extremely expensive (forum states part is $3000) to replace.

"Takats recall" 1ST issue I noticed IS when I gave someone a jump off a dead car battery. As I was driven I noticed my car battery light came on meaning my battery was decreasing power and it did I was on my way home driven I noticed my car losing power in the car shut completely off so I pulled to the side and I called someone to give me a jump the car started back up drove about 3, blocks and the car shut completely off again so I purchased a brand new battery replacing the old battery with an new one. Got another jump to give the the battery some extra juice. After I received the jump I'm back on the road. In the ancient occur again so I called someone to give me a jump. This time the car didn't start. So I had to get it tow home. Got home did some research in found out it was the alternator. replace the old alternator with a new one. 2ND issue I noticed after I replaced the old alternator with the new one I noticed my two fans blower will continuously run for hours when I take my car keys out of the ignition. And due to that that cause my drained my battery causing me to lose power and my car won't be able to start when I put my key in the ignition I don't kno if they connected a wire to keep running if so he was to supposed to tell me that which he didn't. 3RD issue I noticed I recently added new front pads and rotor's new rear pads and rotors 1 new rear passsger side brake caliper. My brake lights still appeared to pop up I told the merchant he told me it could be a sensor failure and get check out at a mercedes benz dealer. 4TH issue the triangle light located in the center of dash flashes occasionally causing under certain circumstances, tapping the brake pedal may not automatically disengage cruise control as expected in certain model year recall subject: suspension: front control arm upper arm .recall: 6/service bulletins: 2

I was driving on a busy intersection in my 2002 mercedes benz ml320 when driving the yellow triangle in the speedometer starts to flash and all the breaks lock up, this IS followed by a stall, thankfully I was able to pull off to the side of the road without being hit. After doing some research I discovered that many mercedes ml320 owners were having this same problem. Specifically the yaw rate sensor. This IS a serious life threatening issue that can injure or worse yet kill someone. You guys need to do a recall before someone dies!

I was pulling away from the curb, steering wheel started making whining noises and harder to turn. I continued on city streets then to a freeway where my car began to overheat. I pulled over at a gas station opened the hood and could see fluid all over right lower driver side. It seemed to be coming from a hose by the power steering cap and the right side of the radiator. Under the car same spot right passenger side I could see power steering and radiator coolant leaking from that area.

On numerous occasions occurring in different conditions regarding speed, weather, road conditions, etc., I have had the vehicle pull hard to the right while engaging the front brakes, both while turning the vehicle and on straightaways. when this occurs, the triangle hazard light and esp lights start flashing. most often I have been able to pull off to the side of the road, thankfully safely, or on one occasion stop in the middle of the road as the car wouldn't allow me to continue driving which was incredibly dangerous and scary. I have taken it to the dealership who replaced the front brake sensors, which didn't fix the problem, and returned to have them again diagnose the issue and declined their recommendations such as replacing the back brake sensors, until I came upon the repeated issues of the stability sensors failing (specifically the yaw sensor). I can't believe that, to date, this has not been a recall issue and no one has been seriously injured or killed due to this problem (i filed a previous claim, but the website went under maintenance and closed my complaint as I was filing and was given ID #10923983, but there IS no information filed in association that I could find hence the re-filing). *tr

On multiple occasions and numerous different speeds, weather, both driving on a straightaway or turning, and other road conditions, the front brakes have locked up on the car causing it to veer right while engaging the brakes. most often I have had to pull over, thankfully safely, or on one occasion, stop in the middle of the road to turn the car off to be able to continue driving which IS incredibly dangerous and scary. I've taken it to the dealership and they had me replace the brake sensors which were obviously not the problem and then recommended other replacements, since the problem continued, that I declined until I found that this was a common problem with the stability sensors in this vehicle (specifically the yaw sensor). I'm amazed this IS not a recall situation and that no one has been seriously injured or killed due to this problem. *tr

Brakes applied on their own without pedal pressure while car was moving at highway speed. front brakes were smoking by the time I found a safe place to stop off the 4-lane road on a side road. rear brakes seemed hot, but not smoking. No warning lights came on. immediately before this highway event, car had just been traveling around 35 mph on hilly side roads with steep ascents and descents. This IS the fourth time brakes have self-applied in a similar manner. after second event, dealer examined car but could not reproduce the problem or find any faults on computer diagnostics. when brakes cool, car restarts without brakes coming on. brake pads and sensors were replaced 6,000 miles earlier; significant brake drag was present for around two hundred miles after that repair; dealer said brakes were self-adjusting and declined to examine car at that time. it was about 4,000 miles after brake pad/sensor replacement that the self-braking problem started.

While driving on the highway at 60mph the vehicle started shaking violently. The brakes started engaging on their own pulling the car to the left and right and nearly bringing the car to a sudden stop. It took a lot of effort to keep the vehicle from pulling into the other lanes and causing an accident. The bas/esp light came on the dash and has stayed on now. This all lasted for about 10 seconds. I was in the 3RD lane of a 4 lane highway during moderate traffic. I was almost rear ended by two different vehicles. I have been researching this issue and found many other drivers with the same thing. This IS a dangerous defect and needs to be addressed. It doesn't take much for a sudden change in direction and speed to cause a severe accident when driving on the highway, and knowing that this vehicle IS capable and know for doing this makes it very dangerous. It makes me wonder how many fatal accidents have occurred due to this problem, but no one knew because it was just assumed the to be driver error. *tr

Driving home on a local street at about 30 miles per hour, approaching intersection, trying to turn, all the sudden, steering wheel became very hard to turn, with no assisting power, car run over to the other side of the road, almost crash into curb. it IS very lucky, there IS no incoming cars, would have crash head on otherwise. car towed to dealer, found steering hose from radiator to steering rack broken off, steering fluid splatting all over engine. dealer stated no recall for steering hose coming out of radiator, but there was recall on steering hose coming out of pump. so this defect was not covered. I urge nhtsa to investigate this dangerous defect immediately, and issue recall to save lives. *tr

ODI opened the investigation based on reports that the subject vehicle brake lamp switch (switch) failure caused 1) inoperative brake lamps (stay on or fail to illuminate), and/or 2) shift interlock failure (shifter locked in park), and/or 3) the cruise control to fail to cancel with brake application.Consumers also reported the illumination of a warning lamp on the instrument panel.The switch contains three sets of electrical contacts and a (normally extended) spring loaded plunger that actuates the contacts as it moves.As installed in the vehicle, the plunger contacts the brake pedal arm and is pushed into the switch; as the driver applies the pedal the plunger extends.One set of contacts (BLS) operates the stop lamps, a second set (EWM) controls the shift interlock system, and a third set (BS) is used by an on-board diagnostic (OBD) system to monitor switch operation.The cruise control monitors the BLS signal to determine when the brake is applied, the primary way the system is disabled when set.The relative timing of contact actuation in response to plunger movement allows the OBD system to detect a switch fault.When a fault is detected a malfunction indication lamp (MIL) is illuminated (driver alert), a diagnostic trouble code (DTC) is stored (for the service technician), and cruise control operation is inhibited (as a failsafe).In its response to ODI's January 2011 information request letter, MB explained its assessment of switch failures which was based primarily on evaluation of field return failures.MB identified both 1) electrical contact and 2) mechanical switch failure mechanisms.According to MB's analysis, electrical contact failure is the predominate failure type and the failure consequence depends on which contact fails.For instance MB claims that BLS contact failures are momentary in nature and do not affect brake light operation but are nonetheless detected by the OBD system, resulting in a DTC and subsequent replacement.Electrical contact failures of the BS and EWM contacts result in a DTC also, and EWM contact failures result in the shifter being stuck in the park (which can be overridden by the consumer).Accordingly MB maintains that electrical contact failures of the switch have no safety consequence since the brake lamps remain operational and the cruise control is always disabled.MB determined that mechanical failures of the switch, which are rare in their assessment, can result from internal wear and/or increased switch operating temperatures.High temperatures occur due to overheating of the BLS contacts and can cause the internal plastic components to melt.In one scenario overheated BLS contacts may melt to the extended plunger and are damaged when the brake pedal is released resulting in the brake lights staying on.In another scenario the increased temperatures and/or internal wear can cause the plunger to stick in the fully depressed position.In this case the cruise may not cancel when the brake is applied and the driver may have to use high brake pedal forces or other means (shifting to neutral or using the cruise master switch) to disengage the cruise.Additionally the vacuum assist can be depleted if the driver pumps the brakes resulting in reduced braking effectiveness and even higher pedal forces.In its March 31, 2011 defect notification, MB stated that to remediate the potential need for excessive brake force it would conduct a safety recall (11V-208) to replace the switch with a more robustly designed component.The recall includes 136,751 model year 2000 - 2002 M-Class and model year 2000 - 2004 M-Class AMG vehicles.Owner notification letters will be mailed

- 11007974Complaint Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy In advance, observe LI82.10-P-078301 "Headlamps or Front Fog Lamps Leaking or Fogged". 1. Prepare headlamp/check for external damage: For headlamps with a closed system 1. Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. 2. If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system 1. Check the headlamps for any external damage and seal off the vent then make sure the cover caps are latched correctly into place. 2. If the headlamp exhibits any external damage, replace the headlamp. Note: A headlamp with external damage is not a warranty or goodwill case. 2. Leak test of headlamp with overpressure: Connect test adapter to pressure tester. (Figure 1) Check test adapter for leak tightness. To do so, connect plug and coupling (picture 2) and apply a maximum overpressure of 30 mbar. The pressure must remain constant. If the pressure does not remain constant, use a new adapter. Seal all the outlet openings using sealing compound and the given diaphragm with the plunger (picture 3). (Picture 4) Make allowance for the different headlamp variants here (there are different outlet openings). Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. Plug the adapter onto the diagnostic socket on the headlamp housing. (Picture 5). Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged. If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is not leaky and the problem is down to natural physical fogging. If a pressure drop of more than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. Replace any leaky headlamps. Note: Desiccant packs can be installed for headlamps that are not leaky. See: LI82.10-P-064766 Fogged headlamp, desiccant pack installed - open ventilation system LI82.10-P-078304 Fogged headlamp, desiccant pack installed - closed ventilation system
- 11007753Complaint Headlamp or front fog lamp leaky or fogged Cause Fogging of the headlamps is a natural phenomenon, which can occur under certain climatic conditions. It does not lead to any technical impairment of the headlamp. Headlamps comply with all applicable standards. If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". Remedy Headlamp: Remedy 1 Clearing fogged/condensed LED headlamps and LED rear lamps: 1. Drive vehicle into workshop (temperature higher than +18 C/+64.4 F) and connect the exhaust extraction. Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood or trunk. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 C/+64.4F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine. 3. Open the hood. 4. Switch off the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Note: If there is no visible reduction in the formation of condensation, check the headlamp for a defect. (See Remedy 2) It is not physically possible to defog the headlamps completely. Fogging does not impair the operation or the service life of the headlamp. Remedy 2 A Damaged headlamp can be identified as follows: 1. Check the headlamp for external damage and that the cover caps and the diaphragm are correctly seated. 2. Check the electrical connectors of the plugs and pins. 3. Check for leak tightness in accordance with LI82.10-P-078307. The test can only be conducted on headlamps. 4. If the headlamp or the rear lamp has any external damage, replace the component part in accordance with the WIS instructions. Note: External damage to the headlamp/rear lamp or faulty seating of the cover caps does not present a warranty or goodwill case. With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. Open ventilation system: LI82.10-P-064766. Closed ventilation system LI82.10-P-078304
