Unknown or Other
Filed Aug 10, 2023LA

Recently discovered that water intrusion in the back of my vehicle is coming from cracks (longitudinal and transverse) on its roof. The roof has no other damage that would have caused the cracks Upon discovery, I took it to my local MB dealership and the attendant that looked at it said he had never seen such cracks and know the cause. I followed up with the Mercedes Benz corporation, who requested for my VIN, and following review of my complaint told me that there was no recall affecting roof cracks for my vehicle. They suggested that I reach out to you (NHTSA online). I am not sure when these cracks developed. I was aware of it earlier this year. The water intrusion, when not dried and depending on what time of the year, could cause mold which can seriously affect the occupants of the vehicle. It would be appreciated if you take a look at this, as well as if there are similar complaints on this GL450 models

Service Brakes

Breaks became unusable due to lost power break fluid caused by corrosion on the lines. Fluid was completely gone and breaks were not effective at all. Dashboard showed RED light with break error. Dealer confirmed that rust build up caused the failure.

Seat Belts
Filed Dec 5, 2022CA

While I was driving the car, with the seat belt fastened, the seat belt suddenly popped out. This was a scary experience! Repeated attempts to fasten the seat belt again did not work. On closer inspection, it appears that something inside the fastening system was probably broken, and the seat belt wasn't getting fastened in there. I immediately took the car to the dealer (Mercedes Benz of El Dorado Hills). After inspecting it, they were able to reproduce the issue (seat belt not getting fastened at all) and advised replacing the seatbelt system on the car. Unfortunately, they did not have the part in stock, so they advised that they would order the part and charge me $800 for this. I can't believe that a fundamental car safety system like this would fail like this. Imagine if there was a car accident and the seat belt just popped out of the fastener, not doing the job it was designed for? Thank you for investigating this issue. It could indeed save a lot of lives, if this is a widespread issue, necessitating a recall campaign from Mercedes.

AFTER PURCHASING THE VEHICLE USED FROM A DEALER (WITH @ 36,000 MILES) I STARTED HAVING TRANSMISSION PROBLEMS WITHIN A YEAR. WHEN I WOULD BE STOPPED ON A HILL/INCLINE AND THEN ACCELERATE THE CAR WOULD VIOLENTLY JERK (AS IF I HAD HIT SOMETHING). IT WOULD NOT GO FORWARD UNTIL AFTER THE SUDDEN JERKING MOTION STOPPED. IT WOULD ALSO BEHAVE THIS WAY WHEN I BACKED UP A HILL OR INCLINE. EVERY YEAR I BROUGHT IT TO THE DEALER TO DIAGNOSE AND FIX IT AND THEY TOLD ME THAT THEY COULDN'T REPRODUCE IT WHEN THEY HAD THE CAR, THEREFORE THEY COULDN'T FIND OUT THE PROBLEM. I ALSO TOLD THEM THAT THE ENGINE LIGHT WOULD COME ON AND OFF INTERMITTENTLY, HOWEVER, THEY WERE UNABLE TO FIGURE OUT THE PROBLEM. EVERY TIME I TOOK IT IN FOR A SERVICE THEY DOCUMENTED THE PROBLEM ON THE ESTIMATE SHEET. HOWEVER, THIS LAST TIME I BROUGHT IT IN THEY WERE ABLE TO DIAGNOSE THE PROBLEM AS A FAULTY TRANSMISSION. IT WOULD SLIP OUT OF GEAR WHEN ON A HILL OR SLIGHT INCLINE WHEN PUT INTO DRIVE OR REVERS FROM A COMPLETE STOP. COME TO FIND OUT WHEN RESEARCHING THESE CARS THAT MERCEDES HAVE HAD THIS PROBLEM WITH THEIR ENGINES FOR A LONG TIME.

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.
