2014 Mercedes-Benz GL-Class Complaint Log

I recently purchased my Mercedes from Auto Boutique in Pearland, Texas (713) 352-0777. 1.The vehicle's air suspension system is constantly grinding, and moving/adjusting while being driven. It feels like the vehicles fame is off balance. 2. The back camera system does not work unless the radio is turned on; which is very alarming not to mention dangerous. 3. All the tires are registering improper inflation errors even though no air has been added or removed. I took the vehicle back to the place of origin; but they are not Mercedes Certified to address the issues. I am terrified to drive the vehicle, and it stays parked in the garage

On this Engine 166 model, I experience noise when Idling and when driving, coming from Engine with no code to indicate what is the problem of the car. This create the heat of the Engine to go up than normal and make the fan to run at high speed. When I call dealer, they told me its common problem on these Engine 166, and I need new Engine. I wanted to get second opinion from different Dealership and I got same answer, its common problems and I need new Engine or to Rebuild. I went online and I ask few people with same car Make, model and year, and the have same problems. My concern is only Dealer knows what is the issue but they don't want to inform Consumer what is the problem, instead they tell Consumer to replace the Engine, We don't how bad it is for safety. The problems it cannot be diagnosed because it doesn't produce any codes to indicate the problem. The noise continue until you turn off the Engine

The contact owns a 2014 Mercedes-Benz GL550. The contact stated that the check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed with leaky exhaust valves. The dealer determined that the exhaust valves needed to be replaced. The vehicle was taken to an independent mechanic, where a similar assessment was made. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the vehicle was not covered under TSB Number: 10233794. The manufacturer referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 104,000.

Leaky exhaust valves

It has makes sound noise and timing chain tension is made very poor not safety , also warming blibd spot frozen not working, display electric poor damage byself tomve fix timing dealer wants 15,000$ to be fix more then value of the suv

The contact owns a 2014 Mercedes-Benz GL450. The contact stated that while driving 65 MPH, the vehicle stalled. The check engine warning light was illuminated. The vehicle was able to be driven to the residence. The vehicle was towed to the dealer, where it was diagnosed and determined that the engine needed to be replaced. The vehicle was then towed to an independent mechanic, who also determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 108,000.

There is a recall on some of the make & models of my truck with different years but, my truck has been having the same issue & I believe that myself & my family may be at risk. The recall states that if the oil level in the ACS reservoir is below the minimum level, the oil may foam & leak out of the vent holes in the reservoir cap. The leaking of oil in the presence of ignition source can increase the risk of fire. I have been having to add two quarts of oil to my car every month for almost a year & there has been no oil in my driveway at all. The oil is going somewhere & I would like for my truck to be put on the recall list & have this issue addressed. My brakes also seem to have an unexplainable issue. Most times they're perfect but, sometimes they vibrate very hard when stopping no matter how fast or slow I'm going at the time. When I get them checked, I'm told that they're fine. I read a recall about the brakes as well.

Car got a check engine for failed turbochargers at 71000 miles. Mercedes refused to acknowledge and get the problem addressed.

Our vehicles computerized self-diagnostic system (OBD) registered faults.

Water has accumulated into the spare wheel well twice causing my ad blue module to be submerged in water, making the system faulty, which then disables the car for use. I have a vehicle that can not start and a repair bill of over 20,000 due to the water accumulation issue. There is a separate recall on other models for this exact problem. This model needs to be included as well.

Tapping noise developed in the engine, after dealership inspection using borescope, scored cylinder walls were found, resulting to engine replacement. Please see: Lena Jamil, et al. v. Mercedes-Benz USA, LLC (Case No: 2:22-cv-08130-FLA-AFM)

There were numerous Engine Oil Leak Recalls by Mercedes-Benz. There was a recent recalls announced in 2023, however, my vehicle 2014 GL450 with now about 50K miles, was not included in the list. Since there have been engine oil leaks problem reported and recalls, I'd like to report my car engine oil leaks problem too. It seems that the engine oil leaks problem is a "design" issue and across many car models and years made by Mercedes-Benz. With that said, it make safety sense to have the recalls extended to those cars with engine oil leaks problem reported. Below is information from dealer diagnostic report on engine oil leaks problem, "Valve Cover Re-seal: FRONT TIMING COVERS RECOMMENDED RESEAL SIPING OIL BOTH SIDES Item Description During a vale cover reseal, the valve cover is scraped and cleaned of any old residue, before a layer of silicone sealant is applied to the cover and then reattached to the head of the engine. Reason If not resealed or replaced, the valve cover will leak oil resulting in a burning smell coming from the vehicle’s engine. A loss of oil over time can result in harmful damage of the engine's internal components."

Front drivers side (Front Left) Aluminum wheel rim is cracked and will not hold tire pressure. We loose about 10 psi per day because of it. Now we have to replace this rim at significant cost. However, that's not the main issue. The main issue is whether this is a manufacturing defect that has put our lives at risk since 2014 (bought it brand new) until now in 2023 - over 9 years. The tire dealer Firestone discovered the crack and let us know. Yes, available for inspection. Yes, safety has been put at risk. Yes, confirmed by local Firestone Tire near us. Insurance may inspect it, we are calling them tomorrow as they are closed now. Tire pressure light went on, and has been on for awhile. But who would have thought to inspect rim, it is steel, and should not have cracked. Friends of mine say that it is possibly an OEM defect as Aluminum cast wheels should not do this. This car has never been in a moderate or serious crash. Fender benders sure, but nothing involving the tires.

The contact owns a 2014 Mercedes-Benz GL350. The contact stated that while inspecting the vehicle, there was oil leaking underneath the vehicle. Additionally, the check engine warning light was illuminated while operating the vehicle. The vehicle was taken to the local mechanic who diagnosed the vehicle and determined that the oil cooler seals were faulty and needed to be replaced. The seals were replaced, and the vehicle was repaired. The vehicle was later taken to the local dealer for transmission failure. The manufacturer was notified of the failure. The failure mileage was 140,000.

The contact owns a 2014 Mercedes-Benz GL550. The contact stated while driving at an undisclosed speed, the steering wheel seized, and the vehicle lost motive power. The check engine and malfunction PP0 warning lights illuminated. The contact was able to steer the vehicle to the shoulder of the roadway. The contact stated that an independent mechanic facility was nearby, so the mechanic and the contact pushed the vehicle into the shop. The vehicle was diagnosed with failed cam shaft gear and lifters. The contact was informed that the cam shaft gear and lifters needed to be replaced. The vehicle was not repaired. The contact stated that the vehicle had been taken to the dealer previously because of an abnormal sound however, the mechanic was unable to duplicate the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.

After picking up children from school, I was driving out of the parking lot down a slow-speed arterial road (35 mph posted speed limit). Roughly 30 seconds after reaching the posted speed limit we heard a loud bang (like a gunshot) and immediately pulled over. The middle section of the panoramic sunroof had shattered. Upon examination on the side of the road there was no apparent impact spot or item in the roadway that would have indicated that particular section of the roof had been struck by anything (no rock, branch, brick, etc), nor were there any other vehicles in the vicinity that might have kicked up an object to hit the roof and nothing else. The sunroof appears to have spontaneously shattered without warning. The temperature outside was moderate (roughly 60 degrees) and the car had been driven earlier in the day without incident. A police report was filed for potential vandalism and I'm currently waiting for the insurance company to contact me to discuss and inspect.

' '['? /The right front headlight was replaced (after receiving a headlight warning) approximately about a year after the warranty expired. The dealership claimed this was due to moisture in the headlight. In August 2021, the left front headlight showed to be having issues with the same error message. Upon further inspection, the mechanic noticed that it was not moisture in the headlight that was causing the short, but an oily substance. The mechanic believes that there might be a bushing in the headlight that might be melting/breaking down due to the heat. This is causing the headlight to short and require a $3500 replacement

Oil leaking and wicking into camshaft position sensors, camshaft magnets, O2 sensors, engine wiring harness and ultimately, the ECU is destroying all electronic components connected to the engine causing misfiring and seizing. The issue is quite prevalent via internet research as potentially thousands of owners with my engine (M278) all experience the same issue. Mercedes Benz advises a $11,000 temporary fix by replacing all engine electronic components but the problem will occur again since the root cause of the oil leak is unknown. Be advised that this is NOT a normal wear and tear issue. This is a design flaw of the engine that placed these components in locations predisposed to contact with engine oil. The root cause of the oil leak is unknown and even Mercedes Benz can not tell why the oil is leaking on these components. If this issue is so prevalent with thousands of owners with the M278 engine in the GL450's, as evidenced by internet searches via Mercedes Benz fan sites, why has no service bulletin or recall been instituted? I am sure your agency can discover numerous examples of this same issue by researching service tickets from Mercedes Benz service centers nation wide. An $11,000 fix is not routine maintenance and Mercedes Benz should be made to fix this prevalent issue via a recall or a service bulletin.

The contact owns a 2014 Mercedes-Benz GL450. The contact stated while the vehicle was stationary, she noticed moisture inside the vehicle. The contact stated that the vehicle filled up with water while it was raining. The contact took the vehicle to an independent mechanic, who stated that the rear hatch was faulty and allowed water to enter the vehicle, but no leaks were found. The independent mechanic had to replace the rubber casing on the rear door hatch, the electrical wiring, and replace the floor carpet. The vehicle was repaired. The contact called the local dealer and made them aware of the failure. The manufacturer had not been informed of the failure. The failure mileage was 124,315.

Oil leaking and wicking into camshaft position sensors, camshaft magnets, O2 sensors, engine wiring harness and ultimately, the ECU is destroying all electronic components connected to the engine causing misfiring and seizing. The issue is quite prevalent via internet research as potentially thousands of owners all experience the same issue. Our local Mercedes Benz dealer indicated this issue "just popped up" immediately outside the warranty period (1 yr) for our used purchase, and would require a replacement of the camshaft, sensors, magnets, and wiring harness to the tune of $14,000. This is a design flaw of the engine that placed these components in locations predisposed to contact with engine oil. The root cause of the oil leak is unknown and even Mercedes Benz can not tell why the oil is leaking on these components. If this issue is so prevalent with thousands of owners with the GL450's, as evidenced by internet searches via Mercedes Benz fan sites, why has no service bulletin or recall been instituted? The overall issue is starting to cause issues with the safety features of the vehicle as well, with alerts (driveline assist, etc) either misfiring or not going off at all.

AS I WAS DRIVING DOWN ON I-27 FROM AMARILLO TO LUBBOCK AT 70 MILES PER HOUR ON 6/22/2020 IN PLEASANT WEATHER AND NO VEHICLES EITHER IN FRONT OF ME OR BESIDE ME, THE MIDDLE PANEL OF THE PANORAMIC SUNROOF SUDDENLY EXPLODED WITH THE GLASS SHATTERING INTO PIECES AND SOME OF THE PIECES DROPPING INTO THE PASSENGER CABIN. THERE WAS NO ROCK STRIKE, HAIL, NOR WAS I TRAVELING THROUGH ANY CONSTRUCTION ZONE. THE AMBIENT TEMPERATURE OUTSIDE WAS 76 F. *TR

1. The power steering wheel is stuck at the top position once in a while. 2. Active curve system pump will fail and leak fluids in 30000-40000 miles.

TL* THE CONTACT OWNS A 2014 MERCEDES BENZ GL450. THE CONTACT STATED THAT THE VEHICLE BOUNCED AND PULLED TO THE LEFT AND RIGHT WHILE DRIVING WITH AN UNKNOWN WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN MERCEDES-BENZ OF CORAL GABLES (300 ALMERIA AVE, CORAL GABLES, FL 33134), AND WAS DIAGNOSED THAT THE FOUR-WHEEL SUSPENSION NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE CONTACT STATED THAT THE FAILURE OCCURRED TWICE. THE FIRST FAILURE WAS REPAIRED AT AN INDEPENDENT MECHANIC. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE BUT, OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 55,000.

TL* THE CONTACT OWNS A 2014 MERCEDES-BENZ GL450. WHILE OPERATING THE VEHICLE, SEVERAL MESSAGES DISPLAYED REGARDING THE PARKING BRAKE RELEASE, TRANSMISSION, AND THE VEHICLE BEING INOPERABLE. ALSO, SEVERAL ELECTRICAL FEATURES MALFUNCTIONED. THE VEHICLE WAS TOWED TO WORLD WIDE MOTORS INC. (3900 EAST 96TH ST, INDIANAPOLIS, IN) WHERE IT WAS DIAGNOSED THAT THE MAIN VEHICLE WIRE HARNESS WAS DAMAGED DUE TO WATER THAT DRAINED FROM THE SUN ROOF INTO THE PANELS OF THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 57,000.

SUNROOF EXPLODED AS I WAS DRIVING DOWN THE FREEWAY. ROADWAY WAS SMOOTH AND THERE WERE NO CARS IN FRONT OF ME SO I'M CERTAIN IT WASN'T A ROCK OR OTHER OBJECT THAT BROKE IT.

THE LANE-KEEPING ASSIST ONLY INTERMITTENTLY WORKS. ON OCCASION IT WILL ALERT AND TAKE CORRECTIVE ACTION, BUT EVEN ON SUNNY DAYS WITH CLEARLY DEMARCATED LANES, IT OFTEN DOES NOTHING. IN RESEARCHING THIS ISSUE, THERE ARE SEVERAL OTHER OWNERS WHO HAVE EXPERIENCED THIS AND HAVE SAID THE MERCEDES SERVICE HAS UNOFFICIALLY ACKNOWLEDGED THERE IS A BATCH OF VIN NUMBERS WHICH HAVE FAULTY SENSORS. WE PURCHASED THIS CAR BECAUSE OF THE SAFETY FEATURES AND MERCEDES NEEDS TO DO SOMETHING TO RECTIFY THIS IN ORDER TO KEEP ITS CUSTOMERS SAFE.

THE CAR RAN OUT OF BRAKE FLUID - THERE WAS AN INDICATOR AND WHEN TAKEN TO SERVICE WE WERE TOLD THE RESERVOIR WAS EMPTY. WHAT IS ALARMING IS THAT THE CAR IS SERVICED VERY FREQUENTLY AND ONE SET OF BRAKES WAS RECENTLY REPLACED (ABOUT 6 MONTHS). MOREOVER THE DEALER STATED THERE WAS NO LEAK. THEY STATED THAT THEY DO NOT REPLENISH THE BRAKE FLUID WHEN REPLACING PADS, IN ESSENCE, BECAUSE THE FLUID SYSTEM IS SO FRAGILE AND THEY ARE AFRAID THEY WILL DO MORE HARM THAN GOOD. IT SEEMS LIKE A STRAIGHTFORWARD PROPOSITION THAT IF THE BRAKES ARE CHECKED AND PADS REPLACED FREQUENTLY, AND THERE IS NO LEAK, THERE SHOULD BE NO POSSIBLE WAY FOR THE FLUID TO GO EMPTY ABSENT A DEFECT IN THE CAR (EXCESS FLUID CONSUMPTION FOR SOME REASON BESIDES A LEAK) OR FAULTY MAINTENANCE PROCEDURES. I BELIEVE THE PRACTICE OF NOT REPLENISHING BRAKE FLUID - DESCRIBED TO ME AS THE NORMAL PRACTICE AT MERCEDES SERVICE, NOT A 1-TIME MISTAKE - IS NEGLIGENT. CONTRIBUTING FACTORS INCLUDE (1) MERCEDES BRAKES ARE KNOWN TO WEAR VERY QUICKLY (ROUGHLY ANNUAL BRAKE PAD CHANGE); (2) THE 2014 MODEL ADAPTIVE CRUISE SYSTEM TENDS TO APPLY THE BRAKES VERY OFTEN, I.E. UNINTELLIGENT ALGORITHM THAT USES BRAKES CONTINUALLY WHILE CRUISING AT 70 MPH ON FREEWAY, NOT SOMETHING A HUMAN WOULD EVER DO

I HAD JUST ARRIVED HOME. THE CAR WAS OFF AND I WAS PARKED IN MY GARAGE. I OPENED THE DOOR BUT IT DIDN'T OPEN ALL THE WAY TO THE FIRST HINGE. MY HAND WAS IN THE DOOR AS IT SLOWLY STARTED TO CLOSE. THE DOOR CAUGHT SLIGHTLY AND THE SOFT CLOSE FEATURE ACTIVATED. MY THUMB WAS CAUGHT IN THE DOOR AND WAS CRUSHED AS THE DOOR SEALED COMPLETELY CLOSED WITH THE SOFT CLOSE FEATURE. I WAS UNABLE TO OPEN THE DOOR DURING THIS TIME. I WAS YANKING ON THE DOOR HANDLE TRYING TO OPEN THE DOOR TO FREE MY THUMB BUT THE DOOR WOULD NOT OPEN UNTIL THE SOFT CLOSE WAS COMPLETE. AS A RESULT MY THUMB WAS CRUSHED. I BELIEVE THAT THIS A DESIGN FAULT WITH THE VEHICLE. THE FACT THAT THERE WAS NO SENSOR TO DETECT SOMETHING IN THE DOOR AS WELL AS NOT BEING ABLE TO OPEN THE DOOR AT ANY POINT DURING THE SELF CLOSE PROCESS PRESENTS MANY SAFETY ISSUES! I REACHED OUT TO MERCEDES DIRECTLY AND THEY SAID AFTER AN EVALUATION THAT THE VEHICLE WORKS THE WAY IT'S DESIGNED AND THAT THE DOOR COULD OPEN DURING ANYTIME OF THE SOFT CLOSE FEATURE. I MADE A SHORT VIDEO SHOWING THAT IN FACT YOU CAN NOT OPEN THE DOOR DURING THE SOFT CLOSE PROCESS. MY FINGER WAS NOT BROKEN BECAUSE I CLOSED THE DOOR ON IT! THE DOOR WASN'T CLOSED ALL THE WAY, IT HAD ONLY JUST SLIGHTLY LATCHED AND WAS THEN CRUSHED BY THE SOFT CLOSE. I EXPLAINED TO MERCEDES THAT THIS WAS VERY DANGEROUS ESPECIALLY WITH MY 3 AND 5 YEAR OLD. IF IT CRUSHED MY THUMB IT WOULD BREAK THEIR HAND!! AFTER I DISPUTED THAT YOU CAN'T OPEN THE DOOR SOMEBODY HIGHER UP AT MERCEDES CALLED ME AND SAID THAT I WAS CORRECT YOU CAN'T OPEN THE DOOR DURING THE SOFT CLOSE AND THAT I WAS RIGHT BUT THAT IS THE WAY THE VEHICLE IS DESIGNED THEREFORE IT'S OPERATING CORRECTLY. WHEN I ASKED WHAT THEY WOULD DO HE SIMPLY ASKED WHY DON'T I JUST GO AND BUY A NEW CAR WITHOUT THE FEATURE!! I EXPLAINED THAT I DIDN'T FELL LIKE SPENDING ANOTHER $100 000.00 WHEN MY CAR IS ONLY 4 YEARS OLD!

DAIMLER AG, (DAG) THE MANUFACTURER OF MERCEDES-BENZ VEHICLES, HAS DETERMINED THAT ON CERTAIN GLE, GLS AND GLE COUP VEHICLES (166, 292 PLATFORM) WITH THE ACTIVE CURVE SYSTEM (ACS), THE OIL IN THE ACS'S OIL RESERVOIR COULD START FOAMING UNDER DYNAMIC DRIVING SITUATIONS IN COMBINATION WITH AN OIL LEVEL BELOW MINIMUM. THE OIL FOAM MIGHT LEAK OUT OF THE OIL RESERVOIR THROUGH THE VENT HOLES IN THE SEALING CAP. DEPENDING ON THE ORIENTATION OF THE VENT HOLES IN THE SEALING CAP, LEAKING OIL COULD SPRAY ONTO HOT SURFACE COMPONENTS OF THE EXHAUST SYSTEM. IN SUCH A CASE THE RISK OF A FIRE CANNOT BE RULED OUT. AS A PRECAUTIONARY MEASURE AN AUTHORIZED MERCEDES-BENZ DEALERSHIP, WILL CORRECT THE OIL LEVEL IF NECESSARY AND REPLACE THE SEALING CAP OF THE OIL RESERVOIR WITH AN OPTIMIZED SEALING CAP TO PREVENT OIL FOAM LEAKAGE. SAFETY RISK: DEPENDING ON THE ORIENTATION OF THE VENT HOLES IN THE SEALING CAP, LEAKING OIL COULD SPRAY ONTO HOT SURFACE COMPONENTS OF THE EXHAUST SYSTEM. IN SUCH A CASE THE RISK OF A FIRE CANNOT BE RULED OUT.

HAVE A MERCEDES GL 350 WITH ONLY 63000 MILES, HAS MADE A SMALL RATTLE SOUND WHEN FIRST PURCHASED THAT I RELATED TO BEING DIESEL, RATTLE HAS GOTTEN WORSE, TOOK IN TO A MECHANIC WHO STATED TIMING CHAIN, I CALLED MY MERCEDES LOCAL DEALERSHIP AND SERVICE MANAGER STATED HE SPOKE WITH AUTO TECHNICIAN WHO "LAUGHED" WHEN HE HAD TOLD HIM MY CONCERN FOR THE TIMING CHAIN AS THE TECH SAID THIS DOESN'T HAPPEN UNTIL VEHICLES ARE VERY HIGH IN MILES LIKE 200000. THEY EXAMINED MY VEHICLE AND THEN STATED IN FACT IT WAS THE TIMING CHAIN AND QUOTED ME 75000. UPON FURTHER RESEARCH THERE HAS BEEN AN ISSUE WITH OTHERS ON THE INTERNET WITH THE GL 350 2014 SPECIFICALLY NEEDING TIMING CHAIN REPLACEMENT WHEN UNDER LOW MILES. CAR RATTLES WHEN STARTED, WORSE WHEN COLD, CONFIRMED TIMING CHAIN BY LOCAL MERCEDES DEALERSHIP.

TO THE BEST OF MY KNOWLEDGE - CERTAIN HIGH END GL MODEL HAVE OPTIONAL EASY THIRD ROW ENTRY. THE SECOND ROW IN SUCH MODELS FOLDS WITH A TOUCH OF A BUTTON. HOWEVER WHEN FULLY DEPLOYED - THE SECOND ROW SEAT'S HEAD REST IN SUCH MODELS PREVENT PROPER INSTALLATION OF KID'S CARSEAT ' SUCH THAT THE UPPER PART OF THE CARSEAT IS PROJECTED FORWARD. I AM 6 FEET AND CAN EASILY PUT THE WHOLE OF MY FORARM BEHIND MY KID'S CARSEAT AFTER INSTALLATION. THE RESULT IS ' A VERY UNCOMFORTABLE FORWARD POSITIONING OF THE KID'S CARSEAT. MY KID HAS REPORTED NECK SPRAIN MULTIPLE TIMES. THE ISSUE DOES NOT RESOLVE WITH USING A BOOSTER ONLY (WITHOUT BACKREST) OR WITH CAR'S HEADREST NOT DEPLOYED ' AS IN ALL SITUATIONS THE CAR'S HEAD REST STILL PUSHES MY KID'S HEAD FORWARD. I BELIEVE THAT IT'S A POTENTIAL SAFETY ISSUE AS WELL. THIS ISSUE HAS BEEN WIDELY REPORTED ONLINE. I GUESS MERCEDES TOOK NOTE OF IT AND AS PER THE LOCAL DEALER - THEY HAVE FIXED IT IN THE NEWER MODELS (2016 ONWARDS). IN ORDER TO FIX MINE - MY FIRST PLAN WAS TO REMOVE THE SECOND ROW HEADREST (THE ONE ON WHICH I INSTALL MY KID'S CARSEAT). DEALER TOLD ME THAT IT'S NOT POSSIBLE - AND INSTEAD RECOMMENDED A RETROFIT. QUOTE WAS $1300. GIVEN THAT IT'S PRIMARILY A MANUFACTURING DEFECT I CALLED MERCEDES USA - THEY REPLIED PROMPTLY. BASICALLY ACKNOWLEDGED THAT THERE IS AN ISSUE AND OFFERED ME $350 IN SERVICE CREDIT, BUT EXPECTED ME TO SHELL OUT THE REMAINING $ 950 OUT OF MY POCKET. WHEN I TOLD THEM THAT IT'S UNFAIR TO DO SO ' AS IT'S PRIMARILY A MANUFACTURING DEFECT ' THE AGENT BASICALLY TOLD ME THAT I SHOULD INSTEAD BE HAPPY THAT THERE'S A REMEDY AVAILABLE AND THAT ALSO AT MY LOCAL MERCEDES DEALER. HE TRIED TO USE MY CURRENT MILEAGE (62K) AS A JUSTIFICATION FOR NOT PICKING UP THE COST - EVEN THOUGH THIS HAS NOTHING TO DO WITH MILEAGE AND MY VEHICLE HAS AN UNLIMITED MILEAGE WARRANTY UNTIL 08/2020.

THE REAR HEADRESTS IN THE MODELS THAT HAVE THE EZ FOLD SYSTEM IN THE 2014 GL550 WILL NOT COME OUT, NOR DO THE HEADRESTS TILT BACK TO A COMFORTABLE POSITION FOR CHILDREN. IN THE MERCEDES FORUMS, THERE ARE DOZENS OF COMMENTS ON THIS AND I HAVE ATTACHED PHOTOS FROM ONE OF THESE THAT MIMICS WHAT MY CHILDREN, 9 & 13 ARE EXPERIENCING - UNABLE TO SIT VERY COMFORTABLY IN THE BACK SEAT, AS THE HEADREST PROTRUDES TOO FAR OUT WHERE THEIR NECKS ARE TOO CRANKED FORWARD, OR HEAD IS NOT IN A GOOD POSITION. I AM SEEKING A FIX WHERE THE HEADREST CAN TILT BACK LIKE THE ONES IN THE VEHICLES WITH MANUAL FOLDING REAR SEATS. TAHNK YOU.

WHILE DRIVING ON THE FREEWAY AT ABOUT 70 MPH THE SUNROOF EXPLODED. WE WERE NOT BEHIND ANOTHER CAR AND DRIVING IN THE MIDDLE OF AN UNPOPULATED AREA ALONG THE !-10 FREEWAY. *TR

YOU NEED TO ORDER A RECALL OF MERCEDES BENZ GL450 (2014) (VIN [XXX]). I HAD TO TAKE THE VEHICLE FOR REPAIR BECAUSE THE BRAKES WERE LOCKING WHEN I DROVE BACK FROM SAN DIEGO AND SEVERAL TIMES I WAS CLOSE TO HIT OTHER VEHICLES. IN ADDITION, THIS WEEK MY BRAKES STARTED SQUEALING AND I HAD TO WAIT UNTIL FRIDAY (5/8/2015) TO HAVE THE VEHICLE INSPECTED. NOW THEY TELL ME THAT AT 16,000 IT IS NORMAL FOR THIS CAR TO BE COMPLETELY OUT OF BRAKES (WORN OUT) AND THAT THE CALIPER DAMAGED THE ROTORS AND THAT THEY WANT ME TO PAY $700 TO REPLACE THE PADS AND ROTORS BECAUSE THEY DO NOT WANT TO HONOR THE WARRANTY. I TOLD THEM THAT THIS CAR WAS FULLY SERVICED A COUPLE OF MONTHS AGO AND THEY SHOULD HAVE REPLACED THE BRAKE PADS IF THEY FELT THAT THEY WOULD BE COMPLETELY WORN OUT. I HAVE CHANGED BRAKE PADS MYSELF IN THE PAST AS A HOBBY AND I KNOW VERY WELL BRAKE PADS LAST BETWEEN 35,000 AND 50,000 MILES BEFORE THE CALIPERS HIT THE ROTORS. I THINK THEY DON'T WANT TO ADMIT THAT EITHER THEY REPLACED MY PADS WITH USED ONES OR THAT THE PADS ARE LIKELY TO CRACK AND THEN THE CALIPER DAMAGED THE ROTORS. THIS TYPE OF VEHICLE IS A SHIP ON A HIGHWAY THAT COULD KILL MANY PEOPLE IF THE BRAKE SYSTEM FAILS WHILE DRIVING AT THE SPEED LIMIT. THIS IS A $90,000 CAR AND IS PROVEN TO BE ONE OF THE UNSAFEST VEHICLES ON THE ROAD. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

TL* THE CONTACT OWNS A 2014 MERCEDES BENZ GL450. THE CONTACT STATED THAT THE TRANSMISSION JERKED AND HESITATED TO SHIFT. THE FAILURE OCCURRED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO THE DEALER SEVERAL TIMES. THE TECHNICIAN REPROGRAMMED THE TRANSMISSION SOFTWARE AND THE MODULE WAS REPLACED; HOWEVER, THE FAILURE PERSISTED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 30.
