Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.

On Mercedes GL350, the trunk/ hatch door will not open from outside. It just stopped working. Therefore, I tried to open it from inside, but there is no manual latch inside to open the trunk/ hatch door. It is a safety issue. The dealer, Mercedes Benz of Richmond, 8225 West Broad Street, charged $235 to open the hatch door. The dealership billed total $1322.48 (after 10% discount $1219.66) to replace the latch and its motor. Kindly help the GL350 owner to have latch installed inside open the door in case of emergency.
Took to South Bay Mercedes dealer in Torrance because of engine light on. Cause: "Obsolete CDI Control Unit Software" Repair: "Updated to latest software version" Charge: $224.99 because "not covered by Emissions Warranty Extension" Do not understand how Mercedes Benz does not provide a critical software upgrade for free or under a recall? Modifications to the diesel engine and its software done less than a year ago.
WHILE THE VEHICLE IS TURNED ON BUT STATIONARY (E.G. STOPPED AT A RED LIGHT IN LIGHT TRAFFIC) I BEGAN TO SMELL DIESEL EXHAUST IN THE CABIN OF THE VEHICLE. THE ODOR WAS VERY STRONG AND I HAD TO LOWER THE WINDOWS IN ORDER TO BREATHE. THE MECHANIC INFORMED ME THAT THERE WAS AN OIL LEAK NEAR THE TURBO. I HAD TO REPLACE THE FUEL INJECTOR AND LEAK LINE, IN ADDITION TO ALL PIPE SEALS AT TURBO.

A BLANKET OF SNOW/ICE FORMED ON MY ROOF DURING THE MORNING. IT WAS NOT REMOVABLE DUE TO FREEZING AND BONDING TO THE ROOF. AS THE CAR HEATED UP INSIDE, THAT BLANKET BECAME LOOSE. WHEN I HIT MY BRAKES ON THE ROAD, THE BLANKET CAME DOWN THE FRONT WINDSHIELD BLOCKING MY VIEW OF THE ROAD. THE WIPERS STOPPED AND WOULD NOT WORK BECAUSE WHEN THEY DO NOT RETURN TO THE PARK POSITION, THEY DO NOT REPEAT THEIR WIPING MOTION. ALSO, THE LIP AT THE REAR OF THE HOOD CAUGHT AND KEPT THE BLANKET OF SNOW IN PLACE AS I BROUGHT THE CAR TO A STOP. MORE CONCRETELY, THE WIPERS ARE FLIMSY RUBBER AND DO NOT WIPE IF ANY OBSTRUCTION PREVENTS THEM FROM COMING TO THEIR DOWNWARD POSITION AT THE BASE OF THE WINDSHIELD. TURNING THE WIPER ON-OFF SWITCH HAS NO EFFECT. THIS PROBLEM CAN CAUSE CRASHES WHEN THE DRIVER'S VIEW IS OBSTRUCTED AND THE WIPERS DO NOT REMOVE THE OBSTRUCTION. I HAD TO EXIT THE CAR IN THE MIDDLE OF THE ROAD AND WIPE THE SNOW AWAY WITH MY HAND AS CARS WERE GOING PAST ME SPLASHING ME. I ALSO NOTI
