A flash from the right headlight had occured. I thought it was the bulb, but turns out the ballist was shorted out. I removed the assembly from the vehicle to change the ballist and because I want to also change the lens on the assembly. When I got the old lens off, I found most of the wiring has heat distress, causing the casings to flake off. I have photos of this issue. The headlights are a high energy assembly and this unsafe condition can lead to a vehicle fire if not taken care of immediately.

Last Wednesday Morning June 06, 2023 I started vehicle up to move it closer to my apartment. Once I shifted into "Drive", immediately the engine revved up and vehicle accelerated in high rate of speed across the parking lot, I was applying the brakes, but they were not stopping the vehicle, it then slammed into wooded area and crashed head first into creek beyond the wooded area. I was dazed and bleeding from cut beneath my nose, I climbed out of vehicle and back up the incline the vehicle crashed downward into. Baltimore County Police responded and I explained to Officer what had happened. He advised me to contact my Insurance Carrier and wrote the Incident Report #. During the time while awaiting my vehicle's retrieval from the wooded area, I then photographed and video recorded the damages once retrieved. The air bags did not deploy when the vehicle crashed yet the complete front grill and hood of the vehicle was smashed in, front tire blown.

SINCE DEC 2017 THE CAR PRESENTED STEERING PROBLEMS AT SLOW SPEEDS, LOSS OF POWER AND HARD TO TURN. TOOK IT TO THE DEALERSHIP THAT INFORMED ME THAT THERE WERE NO ISSUES. I DID FIND IN THE GLOVE COMPARTMENT A RECEIPT FROM A PREVIOUS OWNER IN WHICH THEY REPLACED THE POWER STEERING COMPONENTS IN LATE 2016. IT SEEMS THAT THIS IS A RECURRING ISSUE WITH THE CAR BASED ON THE MANY REPORTED INSTANCES ON THIS WEBSITE.

ME AND MY WIFE OWN A 2008 MERCEDES-BENZ GL-450. IT STARTED GENERATED POWER STEERING PROBLEM ON US SINCE JULY 2017. DURING ANY DRIVING TIME, WHEN WE STEP THE BRAKE TO SLOW DOWN SPEED, THE POWER STEER BECOMES VERY HARD TO TURN REGARDLESS ITS ON FREEWAY OR LOCAL STREET. THE STEER TAKES TREMENDOUS EFFORT TO CONTROL ON LOWER SPEED AND MAKES IT SPECIALLY HARD TO PARK. WE TOOK THE CAR TO A LOCAL MECHANIC FOR A CHECK UP SINCE THE WARRANTY HAS EXPIRED. THE POWER STEERING FLUID LEVEL WAS FINE AND IT MIGHT ENCOUNTER A POWER STEERING PUMP FAILURE ACCORDING TO THE MECHANIC. DUE TO THE MECHANIC'S RESEARCH LATER ON, HE DISCOVERED THAT THERE WERE A HUGE NUMBERS OF RECALL FOR THE SAME POWER STEERING PROBLEMS ON THE SAME MODEL, SAME YEAR OF OUR CAR. WITH THE SUGGESTION OF THE MECHANIC, WE CHECKED THE RECALL INFORMATION ON MERCEDES-BENZ OFFICIAL WEBSITE WITH THE VIN. IT CAME OUT OUR CAR IS NOT ON THE RECALL LIST. THEN ON FEB 6, 2018, I CALLED MERCEDES-BENZ RECALL HOT LINE. THE PERSON WHO I SPOKE TO REFUSED TO GIVE ME ANY INFORMATION BUT A "NO" ANSWER. THE SAME DAY WHEN I SPOKE TO MERCEDES-BENZ CUSTOMER SERVICE, THE GENTLEMAN NAMED "WILL"(IF I REMEMBERED RIGHT) WAS VERY NICE. HE TOLD ME THAT HE WILL WRITE A REPORT OF MY COMPLAINT BUT HE WAS NOT ABLE TO GUARANTEE ME ANYTHING. WE ARE WRITING TO YOUR DEPARTMENT TO FIND OUT IF WE STILL HAVE ANY JUSTIFIABLE LEGAL RIGHT WITH OUR VEHICLE.

Reading this record

NHTSA has issued a do-not-drive warning for a recall on this vehicle.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
