2002 Mercedes Benz ML500 problems

SERVICE BRAKES

There is a serious defect in the YAW rate sensors in these Mercedes ML W163's. Thank God I was driving down a secluded road and nobody was behind me, but my vehicles brakes locked up, on their own, even with my foot on the accelerator pedal, with no warning lights or warning signals. I have no error codes, and my vehicle is well maintained. There are many many people that are having the same issue with their Mercedes ML's. Some people have experienced this happening to them at freeway speeds. The YAW rate sensors are at fault, and send a signal to the ABS pump which in turn locks up the brakes without even touching the brake pedal! This is EXTREMELY DANGEROUS to everyone in the vehicle, and to ANY other vehicle in the area. People can DIE! Again.. This is a terrible defective function of a sensor that will spontaneously apply the brakes fully to lock up automatically with no persuasion from the driver. It is extremely dangerous and can cause fatal injuries. This has been researched thru many Mercedes forums including benzworld.org, mbworld.org, Mercedesforum.com, and ml w163 Facebook forum, all of which many ML owners have experienced the braking system lockup, and in some cases accidents have occurred. Another unfortunate issue in this happening, is that the brake lights do not light up when this sudden braking happens due to the YAW rate sensor malfunction. If there is a vehicle behind a Mercedes ML when this sudden braking occurs, there is NO WARNING LIGHTS, and can cause a serious accident and injury or death! Many people, including myself, do not feel safe behind the wheel of our Mercedes ML's for fear of the brakes locking up in their own because of this poorly programmed default function of a possible faulty YAW rate sensor. This is the worst default function to ever have a vehicle do. I now steer clear of other Mercedes ML's in the road knowing they can automatically lock their brakes for no apparent reason. Please research this and take action!

ELECTRONIC STABILITY CONTROL (ESC)

THIS WAS THE 3RD TIME IT HAPPENED, THIS TIME ON THE FREEWAY IN CALIFORNIA AND LASTED UNTIL THE CAR CAME TO A STOP.

STEERING

IN MARCH OF 2003 MERCEDES INITIATED A RECALL FOR MY VEHICLE FOR A PROBLEM WITH THE POWER STEERING HOSE, THE CAR WAS TAKEN IN FOR SERVICING AND THE PROBLEM SUPPOSEDLY FIXED. ON APRIL 2ND OF 2008 I TOOK THE CAR TO MERCEDES BECAUSE IT WAS MAKING A REALLY LOUD SOUND I WAS TOLD THAT THE POWER STEERING HOSE WAS LEAKING A $665 FIX. I HAD THE WORK DONE. ON APRIL 15TH OF 2008 THE CHECK ENGINE LIGHT CAME ON TOOK THE CAR BACK TO MERCEDES AND WAS TOLD THE POWER STEERING PUMP NEEDED TO BE REPLACED A $1211 FIX. I WAS FURIOUS AT THIS POINT. IN SEPTEMBER OF 2008 THE NHTSA ISSUED A RECALL ON THE MODEL FOR A PROBLEM WITH THE CLAMP FOR THE POWER STEERING HOSE. I CONTACTED MERCEDES WHEN I BECAME AWARE OF THIS RECALL EARLIER THIS WEEK. I WAS TOLD THAT THE HOSE THAT WAS REPLACED ON MY CAR'S POWER STEERING SYSTEM IS NOT THE ONE BEING RECALLED. I DO NOT QUALIFY FOR THE RECALL BECAUSE MY CAR'S VIN NUMBER WAS NOT A PART OF THE SPECIFIC CARS THAT WERE RECALLED EVEN THOUGH IT WAS INCLUDED IN THE 2003 RECALL. I ARGUED THAT MY POWER STEERING PUMP WENT BAD BECAUSE OF MERCEDES NEGLIGENCE WITH THE HOSE ISSUE AND I HAVE GOTTEN NOWHERE WITH THEM. THE DEALER WILL NOT HELP ME AND MB USA WILL NOT HELP ME BECAUSE MY VIN IS NOT ON THAT RECALL EVEN THOUGH I AM STILL HAVING THE ISSUE AND YES MY CAR IS STILL LEAKING FLUID ALL OVER MY GARAGE.

STEERING

THIS CAR WAS PURCHASED IN SACRAMENTO CA IN AUG OF 06, AT THIS TIME WE ALSO PURCHASED AN EXTENDED 2 YEAR WARRANTY WHICH WE UNDERSTOOD TO BE EXPIRING IN AUG OF 08. THE CAR WORKED FINE WITH NO ISSUES UNTIL SEPT OF 07. I STARTED THE CAR AT 4 AM TO HEAD TO WORK AND IT MAKE A REALLY LOUD NOISE, IT GOT WORSE WHEN I TURNED THE STEERING WHEEL. I CONTACTED THE MB DEALER AND WAS TOLD TO BRING THE CAR INTO THE DEALERSHIP. I EXPRESSED CONCERN ABOUT NOT WANTING TO DRIVE THE CAR MAKING THAT SOUND, HE ASSURED ME THAT IT WAS FINE. I BROUGHT THE CAR INTO THE DEALERSHIP AND WAS TOLD IT JUST NEEDED POWER STEERING FLUID SO THEY WILL TOP IT OFF FOR ME AT NO CHARGE AND IT WILL BE FINE. TOOK MY CAR AND LEFT. TWO MONTHS LATER ON NOV1ST, SAME ISSUE, TOOK THE CAR IN AGAIN, WAS TOLD WE WILL JUST TOP IT OFF FOR YOU AT NO CHARGE, TOOK MY CAR AND LEFT AGAIN. ON NOV 15TH I HAD MY CAR TRANSFERRED TO ATLANTA BY MOVING TRUCK SINCE I WAS MOVING BUT DID NOT WANT TO PUT THE MILEAGE ON IT. TOOK IT TO MB FOR ITS REGULAR SERVICING 1 WEEK LATER NO PROBLEMS WERE FOUND AT THAT TIME."" ON APR 5TH 08 THE NOISE CAME BACK, I TOOK THE CAR TO THE DEALERSHIP AND WAS TOLD WE WOULD JUST TOP IT OFF FOR YOU BUT WE NOTICED THAT THERE ARE SOME LEAKS SO YOU MAY WANT TO BRING IT IN TO GET THAT CHECKED OUT. I DID THIS 2 DAYS LATER AND WAS TOLD IT WAS THE POWER STEERING HOSE AN $800 FIX THAT WAS NOT COVERED BY MY WARRANTY. I HAD THE WORK DONE. ON APR 20TH MY CHECK ENGINE LIGHT CAME ON, I WENT BACK TO THE DEALERSHIP HAD TO PAY AGAIN FOR THE DIAGNOSTIC TO BE DONE, EVEN THOUGH ONE WAS SUPPOSEDLY DONE 2 WEEKS PRIOR. NOW IT WAS THE POWER STEERING PUMP AT A $1400 FIX. I WAS PISSED. HOW DID THEY MISS THIS 2 WEEKS PRIOR? HOW DID I EVEN KNOW IT WAS THE HOSE AT FIRST AND NOT THE PUMP? HOW WAS THIS FOUND CONVENIENTLY AFTER MY WARRANTY IS NO GOOD WHEN THE NOISE WAS THERE BEFORE? A COMPLIMENTARY DIAGNOSTIC WAS DONE BY THE SERVICE MGR ON AUG 29TH AND NOW I AM BEING ASKED TO PAY $2100 FOR FIX THE PROBLEMS FOUND. THE WARRANTY SHOULD BE HONORED.

VISIBILITY:WINDSHIELD WIPER/WASHER

WHILE DRIVING, ML500 BEGAN TO BRAKE RANDOMLY . ALSO ABS TURNED ON WHILE STOPPING AND ACCELERATING. ALSO BRAKES WERE CONSTANTLY SCREECHING. WARNING LIGHTS FOR ABS, BAS, AND WASHER FLUID. FLUID LEVEL WAS FINE. I TOLD DEALER ABOUT THESE PROBLEMS BEFORE WARRANTY HAD EXPIRED. THEY RAN A DIAGNOSTICS TEST AND FOUND NOTHING WAS WRONG. THEY ADVISED ME TO BRING THE VEHICLE IN SHOULD THE SAME EVENTS OCCUR. (THE RANDOM BREAKING BEGAN TO OCCUR AFTER WARRANTY EXPIRED). THE PROBLEM CONTINUED TO PERSIST AND WITH THE FAILURE OF ABS SYSTEM, I BROUGHT THE ML500 BACK TO THE SERVICE CENTER. AFTER TWO DAYS, I RETRIEVED THE VEHICLE AND THE COST TO REPAIR WAS $1100.00. "CONVENIENTLY" THEY FOUND THE SAME PROBLEMS I SPOKE OF BEFORE AFTER THE WARRANTY WAS UP. WE HAD NO CHOICE BUT TO PAY TO RESTORE FUNCTION TO THE VEHICLE. AFTER TAKING IT HOME WE NOTICED THAT THE THERE WAS NO SOUND IN THE VEHICLE. THE SOUND AND NAVIGATION VOICE WORKED PERFECTLY BEFORE GETTING SERVICE. AND AFTERWARDS IT DID NOT. WE CALLED THE SERVICE CENTER, AND THEY SAID TO BRING IT BACK AT OUR EARLIEST CONVENIENCE, AND THEY WILL FIX THE PROBLEM. I ASSUME THAT THIS WAS A MISTAKE ON THEIR PART. WHEN I RETURNED TO RESTORE THE SOUND THEY APPROACHED ME AND TOLD ME THAT A "VOICE MODULATION UNIT" BENEATH THE DRIVER'S SEAT HAD GONE OUT, AND THAT IT WOULD COST $750.00 PARTS AND LABOR TO REPAIR. THEY TRIED TO EXPLAIN TO ME THAT THIS WAS JUST A COINCIDENCE, AND THAT THE UNIT WAS IN NO WAY RELATED OR CIRCUIT LINKED TO THE SENSORS THEY REPLACED. I BELIEVE THAT THEY MUST HAVE MISTAKENLY SHORTED IT. WE HAVE SPENT ALMOST $10,000.00 IN THE PAST YEAR FOR REPAIRS TO THIS VEHICLE AND ONE OTHER MERCEDES. THEY DID NOT GOOD WILL CREDIT THE WORK SO I DID NOT ACCEPT THE REPAIR SERVICE. THERE IS NO SUCH THING AS A $750.00 COINCIDENCE. THE SOUND WORKED FOR ALMOST 80,000 MILES BEFORE SERVICE AND NOW RIGHT AFTER IT FAILED... I DON'T THINK SO. THE MERCEDES SERVICE CENTER REFUSED TO DO ANY WORK FOR WHAT WE BELIEVE TO BE THEIR RESPONSIBILITY.
