Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

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.

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.

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 NOTICED THAT BOTH FRONT WIPERS WERE CAKED WITH ICE. THIS MEANS THAT WHEN I REMOVED THE SNOW FROM THE WINDSHIELD, THE WIPERS ONLY SMEARED ICE AND SALT ALL OVER THE WINDSHIELD AND I COULD NOT SEE THE ROAD CLEARLY. THE FIX IS EASY AS TO STALLED WIPERS. THE SYSTEM MUST BE REPROGRAMMED SO THE WIPERS CONTINUE TO WIPE EVEN IF THE WIPERS DO NOT RETURN TO THE PARK POSITION (BECAUSE OF ACCUMULATED SNOW, FOR EXAMPLE). AS TO ICED-OVER WIPERS, THE MANUFACTURER MUST INSTALL HEATING ELEMENTS IN THE BASE OF THE WINDSHIELD OR INSIDE THE WIPERS OR PROVIDE FOR DUCTED HEAT (FROM THE MOTOR). I AM WRITING THIS REPORT BECAUSE THE CAR IS AN ALL WHEEL DRIVE DIESEL TRUCK INTENDED FOR HEAVY DUTY USE IN ALL ENVIRONMENTS AROUND THE GLOBE. HOWEVER, I CANNOT SEE THROUGH THE FRONT GLASS IN A MINOR SNOW STORM IN NEW YORK CITY. WHAT IF I CRASH AND CAUSE A FATALITY? AM I TO BLAME BECAUSE I COULD NOT DEAL WITH THE SNOW? *TR
