general problems of the 2015 Mercedes Benz GL450

My 2015 mercedes-benz gle 450 experienced an unexpected vehicle fire on Feb 13th 2026. The vehicle was just parked when I noticed smoke from the engine. The vehicle caught fire within a short period of time, and 911 was called. There was no known external cause for the fire. The incident appeared to originate from the engine compartment. This created a serious safety hazard and posed a risk of injury and property damage. The fire required immediate response from the fire department, and the vehicle was declared a total loss. The vehicle is currently in the possession of the insurance company. This incident raises concerns about a potential mechanical or electrical defect. A vehicle should not catch fire under normal operating or parked conditions. I am requesting that this incident be reviewed as a potential safety defect.

To whom it may concern: I am writing to formally request the national highway traffic safety administration’s assistance regarding a critical safety defect in my 2015 mercedes?benz gl?450 (m278 engine). I purchased this vehicle in October?2024 with 76,000 miles, and it now has about 87,000 miles. Alarmingly, I recently received a quote for $13,000 to repair a camshaft failure and extensive electrical damage. I was unaware of these issues when I purchased this car. I bought it under the illusion that it would be a safe vehicle for me and my children. As a single parent and teacher I invested in this vehicle what I could afford and felt I had purchased a safe, reliable vehicle. I am devasted to have a proposal for repairs in excess of $13,000 from a mercedes dealership who diagnosed the car. This caused me to do some research and I found the Gl450 has a known and widespread defect. I also found, that this causes the cam shaft to need to be repaired and that this is not normal wear-and-tear—it is a systemic design vulnerability common across Gl450 models. This can result in the engine seizing from what I was told and that directly poses a substantial risk when driving. From what I found this is a common issue with this car and I did not know that when I purchased it. This is a design flaw, not a misuse of the vehicle. Finally, a $13,000 repair to make this car safe and road ready is astronomical and is not aligned with a normal maintenance cost- manufacturer accountability is warranted here. I respectfully request that the NHTSA: investigate whether a safety recall or extended warranty program is appropriate for this known defect in the Gl450. Require mercedes?benz to provide a comprehensive repair solution for me and repair this defect in my car's engine under the manufacturer's expense. And finally, for mercedes to make customers affected by this aware of this engine defect and long term risks associated with this issue. Respectfully, alyssa begin.

The contact owned a 2015 mercedes-benz Gl450w4. The contact stated that the vehicle was in the dealer for 12 days for a oil change. The contact son drove the vehicle 2 days later, at an undisclosed speed when the vehicle started smoking from the engine. The contact's son pulled over when the vehicle caught fire completely. The fire marshals came out to extinguish the fire, there were no injuries. No police report was filed. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 110,000.

The rubber sealing around the lift gate failed on the vehicle and water seeped inside the vehicle and entire bottom of the vehicle underneath the floor board thereby damaging the electronic components, engine wire harness and headliner thereby rendering the vehicle was beyond repair. This issue led to mold to grow on the roof liner inside and on the seats which caused breathing issues for me and my family. This put our safety at risk! after talking the vehicle to authorized Mercedes Benz dealer in san jose CA I was told that this is a known defect with the vehicle about which Mercedes Benz inc is well aware for years and has not fixed it or recalled vehicles having this safety issue. I had purchased this vehicle from Mercedes Benz of pleasanton on 6/10/2015 as certified pre owned (cpo) but I was not informed that this safety issue existed. I was informed by Mercedes Benz of san jose that the vehicle could not be repaired as mold would pose a health hazard for the occupants and the vehicle was deemed to be beyond repair and totaled. I had also purchased extended warranty at the time of purchase in 2015 but the dealership did not honor it for repairs.
