2017 Mercedes GLS

I was driving around and my [XXX] daughter was complaining that the seat was getting super hot . I told her to stop playing with the seat warmer she then replied she was not . I kept driving and then she again told me it was burning her so i pulled over and saw that her leg was super red and i saw the seat was pretty melted . I called mercedes care center and they adviced me to take it to my local mercedes dealer . They are quoting me almost 4000 dollars and also replied with this message, “Good afternoon [XXX] we heard back from Mercedes Benz CAC and they have advised us they are not offering any assistance towards the seat repair. Please contact me when you have a moment. Thank you.” INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Crash

The contact owns a 2017 Mercedes-Benz GLS450. The contact heard an abnormal humming sound when the vehicle was started, and the humming sound grew louder over time. The contact believed that the humming sound was coming from the driver's side headlamp. The contact stated that the headlamp was equipped with a small internal fan to dissipate heat. Additionally, other electrical failures were occurring, and the vehicle was taken to a local dealer. The dealer diagnosed the vehicle and determined that the blower motor had failed and needed to be replaced. The vehicle was repaired; however, the humming sound returned. The vehicle was taken to the dealer on two more occasions, and the dealer replaced the timing belt and the alternator, however the failure reoccurred. Recently, while touching the door handle, the contact heard a humming sound that was very loud. The vehicle was taken back to the dealer, and it was determined that the driver's side headlamp assembly needed to be replaced. The vehicle was not repaired. The contact researched online and related the failure to NHTSA Campaign Number: 20V626000 (Electrical System, Steering, Exterior Lighting, Visibility); however, the VIN was not included. The manufacturer was contacted and confirmed that the VIN was not included in the recall. The failure mileage was 135,500.

My 2017 Mercedes-Benz GLS 450 is experiencing serious and unpredictable transmission behavior related to the valve body and shifting mechanism. The transmission sometimes fails to engage Park, shifts on its own without driver input or attempts to engage Reverse unexpectedly. On multiple occasions the vehicle has moved or rolled after being placed in Park and once it appeared to shift itself toward Reverse. This behavior is a clear safety risk as the vehicle can suddenly lose control or move unexpectedly. It happens intermittently, without any dashboard warnings and often resets temporarily after restarting the car. According to multiple owners posting on Mercedes-Benz forums (including MBWorld, BenzWorld, and Mercedes-Benz Owners Club discussions), this issue is common among GLS and other Mercedes models using the same transmission. Many owners report identical symptoms: transmission slipping into Neutral or Reverse, failure to engage Park or erratic shifting caused by a malfunctioning valve body, defective solenoids or Transmission Control Module (TCM) faults. Some have shared diagnostic codes such as P073E and P07B7 that point to reverse and park circuit errors. Mercedes technicians and independent repair specialists who have posted on these forums frequently identify the valve body assembly as the source of the issue. Common explanations include internal hydraulic pressure faults, electrical connector leaks or sensor failures inside the valve body. Owners have been quoted thousands of dollars for valve body replacements as i was billed $2300+. This problem is not isolated to my vehicle and appears to be a recurring design or manufacturing defect that affects multiple model years and platforms sharing this transmission. Because the vehicle can unexpectedly shift or fail to hold Park, it creates an immediate safety concern for both drivers and bystanders. I have video of this dangerous issue

On July 23, 2025, I drove my Mercedes-Benz GLS 450 to a medical appointment. After arriving, I parked near the valet station, turned off the car, and went inside to check in at LabCorp. Within two minutes, witnesses reported black smoke from the hood — followed by a violent explosion that shook the office building and triggered a multi-unit response from local fire and police departments. When I came downstairs, my vehicle was engulfed in flames. The front end was completely destroyed. Mercedes-Benz USA sent an investigator on September 8, 2025 to examine the wreck. Despite numerous follow-ups, I have received no written report, no findings, and no communication from Mercedes-Benz since that inspection detailing any relevant information. Safety Context: In March 2024, Mercedes-Benz issued Recall #24V-207, affecting 2019–2023 GLE and GLS models, citing a defective 48-volt ground connection that could cause a fire. My incident occurred in a GLS 450 model and appears consistent with this recall defect. If confirmed, this could indicate that the recall did not capture all affected VINs or that repairs were not properly executed. This incident was minutes from being fatal — and could easily have occurred on the highway or in my garage or with my 4 children inside. The lack of corporate response for over two months raises serious concerns about consumer safety, recall effectiveness, and corporate transparency.

Vehicle Information: Make: Mercedes-Benz Model: GLS 450 Year: 2017 Component: Visibility/Sunroof/Panoramic Glass Roof VIN: [XXX] Incident Date: [XXX] Complaint Summary: I am filing this complaint regarding a serious and dangerous safety defect in my 2017 Mercedes-Benz GLS 450. Without warning and while driving, the panoramic glass sunroof suddenly shattered and exploded, sending glass shards and debris into the vehicle cabin. My two young children were seated inside at the time, and glass pieces fell directly onto them, causing extreme distress and posing a severe risk of injury. There was no impact or external cause—the sunroof shattered spontaneously. The incident left glass scattered throughout the interior of the vehicle, including on the seats, floor, and children’s car seats. Fortunately, my children were not severely injured, but the potential for serious harm was extremely high. After researching this issue, I discovered that this is not an isolated incident. Numerous complaints have been filed with the NHTSA and other authorities regarding spontaneous sunroof shattering in Mercedes-Benz vehicles, including this model. Additionally, I understand that a federal judge recently approved a class action lawsuit addressing this exact issue, further highlighting the severity and prevalence of the defect. This is a significant safety hazard that must be addressed. I urge the NHTSA to investigate this issue further and take appropriate regulatory or enforcement action to ensure the safety of all vehicle occupants. Additional Details: No recent repairs or modifications to the sunroof or roof area. Vehicle was in motion on a clear day with no overpasses or external objects that could have impacted the roof. The noise was loud, like an explosion, followed by immediate glass breakage. I have retained photos of the damage and can provide them if needed. Requested Action: Please investigate this matter urgently. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Charcoal canister not actuating correctly so was replaced and checked. Gas cap also replaced Several days later Check engine light returns. Code continues to say "Small leak in the EVAP system." Every time the code is cleared it returns and Check Engine light returns. This has been going on for 7 months. Car cannot obtain the required SMOG inspection in California that is required for an annual registration of the vehicle. I believe the vehicle may need to be part of the Emission Service Campaign 2024030005 which has effected 16 other vehicles. Mercedes tells me that an update to the Engine Control Software will not be allowed because my vehicle is not one of the 16 vehicles that are currently effected by this issue. The issue is for the same make, model and year as my vehicle.

Our car, Mercedes GLS 450, caught on fire after pulled into the garage from a short drive on local streets, which resulted a total loss on our house. After pulling into the garage, the home link didn't work when tried to use it to close the garage door. Upon coming out of the car, smoke came out from under the hood and soon after it became flame. We attempted to extinguish the fire with a fire extinguisher as it appeared with hood still closed and fire immediately came back. By the time the firefighters came, there was a full fledged fire. The fire has burned the car beyond recognition and the garage was burned too. The fire and smoke has caused a total loss on our house. There were NO warning lights or warning messages at all before smoke or fire started. Investigators hired by Mercedes Benz inspected the burnt car and concluded the fire was due to a missing oil cap. While questionable the oil cap was the source of the fire, it seems the GLS 450 didn't have a sensor for missing oil cap to trigger a warning light or warning message, which is what some less sophisticated cars have because modern engines have positive crankcase ventilation. If indeed missing oil cap could cause full fledged fire, shouldn't Mercedes put a sensor to warn the customers? There is a recall, see link below, on almost all Mercedes model cars in Jan. 2022 for the reason that the car could catch on fire. Our GLS was built just two months before the starting timeline on the recall and it caught on fire and burned our house. Could it be coincidence or did our car catch on fire due to the exact same reason on this recall?

We had our Mercedes GLS550 2017 with 59,295 overheat and call for immediate shut down on the Massachusetts Turnpike with my wife and child in the car. It was quite a dangerous situation because the failure caused by hose assembly 166-830-15-00 clamp (as described by the dealer as the reason for the loss of fluid and hose failure) caused almost an immediate overheating. The service advisor stated that it is "a quite common failure". I was quite suspicious, because just 11 days prior and 138 miles prior they had performed an Oil Change (Service B9), and thought their mechanic must have damaged the hose fitting they claimed broke. When I looked at the schematic, the fitting is quite close to the Oil Filter Cap, so I assumed that the mechanic accidentally knocked the plastic clamp and broke it. However, they said this was a "normal failure" on these cars. I am a data scientist and have requested failure rates for similar autos in the data cohorts of 50,000, to 60,000 miles and 4 to 5 years old. It woudl be also nice to see if there was data available that included Post B( service visits for the same failures. I was surprised they tracked this data since I was told it was a common failure of this part. Looking at the design of where the host runs, it is certainly exposed to a mechanics tools removing the Oil Filter wrench. If this is common, I would like to help other families with young children being stranded by the side of a busy highway. In this case, I told my wife to drive to the closest safe point even though the engine warning system said to stop immediately. The engine seems to survive fine. I dont know if you record other data on this type of hose assembly failure, but a redesign with non-plastic clamp might be more durable and more appropriate.

WE HAD T DRIVE THE REMAINING 400 MILES WITH THE BROKEN SUNROOF. WHEN WE GOT BACK HOME , WE CONTACTED MERCEDES AND ASKED THEM ABOUT THE SUNROOF. THEY BASICALLY DID NOT ACCEPT ANY RESPONSIBILITY FOR ANYTHING EVEN AFTER WE TOLD THEM THAT AFTER GOOGLING ( MERCEDES EXPLODING SUNROOF) A TON OF ITEMS CAME UP INCLUDING SEVERAL LAWSUITS. MERCEDES DOES NOT SEEM TO WANT TO ACCEPT ANY RESPONSIBILITY FOR THE SUNROOF. MY WIFE AND I COULD HAVE BEEN KILLED.

I PURCHASED A 2017 GLS 550 IN JANUARY 2018 FROM LOEBER MOTORS IN LINCOLNWOOD ILLINOIS. THE STICKER ON THE VEHICLE REPRESENTED THAT THERE WERE 'ALL SEASON' TIRES ON THE VEHICLE. AFTER NUMEROUS GUARANTEES FROM THE SALESMEN, I WAS ASSURED THAT THE VEHICLE WOULD BE 'SAFE' ON THE FACTORY TIRES AS THEY WERE REPRESENTED AS ALL SEASON. IT WAS NOT UNTIL I FOUND MYSELF DRIVING THROUGH A SPRING SNOWSTORM IN WISCONSIN THAT I REALIZED THAT THERE WAS SOMETHING TERRIBLY WRONG WITH THE WAY THE VEHICLE WAS HANDLING IN THE STORM. I WAS CONCERNED THAT THE VEHICLE WAS GOING TO END UP ON THE SIDE OF THE ROAD, OR IN A HORRIBLE ACCIDENT, AS THE VEHICLE WAS ALMOST UNABLE TO CONTROL. ALMOST EVERY OTHER CAR ON THE ROAD SEEMED TO BE UNFAZED BY THIS STORM, YET MY $100,000 VEHICLE WAS DRIVING LIKE A ROLLER SKATE.AFTER MUCH RESEARCH, NUMEROUS CONVERSATIONS WITH THE DEALER AND CONTINENTAL TIRES, IT HAS COME TO LIGHT THAT THE TIRES ON ALMOST ALL GLS 550'S ARE ACTUALLY THE CONTINENTAL CROSS CONTACT UHP'S. CONTINENTAL HAS VERBALLY CONFIRMED(ON A RECORDED LINE) AND THROUGH EVERY BIT OF LITERATURE ONLINE, THAT THE TIRES ARE ACTUALLY SUMMER TIRES AND SHOULD NOT BE DRIVEN IN WINTER/SNOW CONDITIONS.WHILE THE TIRES MAY HAVE AN M AND S ON THE SIDEWALL, THIS WAS A DESIGNATION REQUESTED BY MERCEDES TO DEFINE THESE TIRES AS 'ALL SEASON' AS THEY MEET THE TREAD DESIGN FOR THE MINIMUM STANDARDS FOR ALL SEASON. CONTINENTAL HAS STATED THE EXACT OPPOSITE AND DOES NOT EVEN PROVIDE SAFETY DATA FOR THESE TIRES IN WINTER CONDITIONS, AS THEY ARE SPECIFICALLY DESIGNED AS A SUMMER/PERFORMANCE TIRE.

WHILE DRIVING DOWN THE TURNER TURNPIKE (BETWEEN TULSA AND OKC, AROUND 70-75MPH)THE VEHICLE WITHOUT WARNING HAS SWERVED LEFT AND RIGHT ON THREE DIFFERENT OCCASIONS. THE ACTION FELT AS IF THE HAND OF GOD WAS THROWING US LEFT AND THEN RIGHT. THE CAR HAS A MIND OF ITS OWN. THEN THE LAST TIME THAT I DROVE THE CAR IT SUDDENLY YANKED ME OFF THE ROAD WITHOUT WARNING, LITERALLY TRYING TO KILL US. THIS LAST INCIDENT OCCURRED WHEN THE CAR HAD AROUND 1,750 MILES ON IT. THE THING IS DANGEROUS! I NOW OWN A CAR THAT I CAN'T PUT MY FAMILY IN AND SHOULD NOT BE ALLOWED ON THE ROAD. THE SHAKING ORIGINALLY STARTED OUT AS SOON AS I PUT THE CAR ON THE HIGHWAY FOR THE FIRST TIME, TWO DAYS AFTER PURCHASING IT. BUT THE SHAKING WAS ONLY A SHAKE THAT WOULD BE DESCRIBED AS AN IRRITANT. HOWEVER, IN MBOKC'S EFFORTS TO CORRECT THE PROBLEM THEY MAY HAVE CREATED THE TWO NEW PROBLEMS WHICH ARE FAR MORE TROUBLING. MBOKC REPORTED TO ME THAT AFTER DRIVING THE CAR 600 MILES THEY WERE ONLY ABLE TO EXPERIENCE THE PROBLEM TWICE. THEREFORE, THEY WEREN'T ABLE TO FIX THE CAR UNLESS I CAN GET THE CAR TO PREFORM THAT WAY ALL THE TIME. IT'S ALSO FUNNY (ACCORDING TO THE RECORDING WHICH I HAVE) THAT THEY DROVE THE CAR SEVERAL HUNDRED MILES BEFORE THEY EXPERIENCED THE PROBLEM TWICE . IT ALSO WAITED UNTIL I DROVE IT 1,750 MILES BEFORE IT TRIED TO KILL ME! NOT SURE IF I SHOULD WAIT UNTIL AN ACCIDENT OCCURS TO ACT. PLEASE ADVISE!

VEHICLE IS ONLY 3 WEEKS OLD. A FAULTY ENGINE WIRE HARNESS CAUSED THE VEHICLE TO CEASE OPERATING IN TRAFFIC AND PUT MY FAMILY IN A POTENTIALLY LIFE THREATENING SITUATION. MERCEDES DID NOT REPLACE BUT ONLY "REPAIRED" THE WIRE, WHICH WE WERE TOLD WAS NOT ASSEMBLED CORRECTLY AND WAS PINCHED IN A BRACKET AND SUBSEQUENTLY CHAFED, WHICH CAN POTENTIALLY STILL CAUSE A LIFE THREATENING ENGINE MALFUNCTION DURING NORMAL OPERATION. MERCEDES IS NOT WILLING TO REPLACE THE ENGINE HARNESS WIRE, NOR REPLACE THE VEHICLE. I FEAR FOR THE SAFETY OF MY FAMILY.

SEALS HAVE BEEN REPLACED PRIOR TO ANY ADDITIONAL PROBLEMS WITH THE VEHICLE OR DRIVE TRAIN. DEALER REPLACED SEAL QUICKLY AND PROMPTLY. DEALERSHIP WAS A PLEASURE TO DEAL WITH.
