Each component in detail
What the reports in each category say, in the owners' own words
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
My car has only 28,392 miles on it, but the yellow check engine light recently came on due to a faulty oil pump solenoid. I took it back to the dealership, and the repair cost was a staggering $7,000; they told me this is a common issue with this Mercedes engine. If this fails to function, engine noise will increase while driving and fuel consumption will rise; there may also be other unknown risks. The issue stems from a manufacturing defect that causes the malfunction indicator light to remain illuminated, preventing the vehicle from passing the annual emissions inspection and rendering it ineligible for legal road use; furthermore, the repair entails removing the front subframe and oil pan, resulting in unreasonably high repair costs.
While driving on I-84 between [XXX] and [XXX] , the vehicle experienced a sudden and complete engine failure with no prior warning. The engine seized, resulting in an immediate loss of power while traveling at highway speed, creating a dangerous situation in active traffic. The driver was fortunate to safely pull the vehicle onto an exit ramp. State police arrived and positioned their vehicle behind it to prevent a potential collision with other vehicles. There were no warning lights or prior symptoms before the failure. The vehicle had approximately 80,000miles and was regularly maintained. The issue has been confirmed by a service center, and the engine may require full replacement. The sudden and unexpected nature of this failure raises serious safety concerns and potential defect issues. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2021 GLE350 - 4JGFB4KB7MA355768 purchased December 30, 2024 with 35,000. miles. Current milage 61,933. There is a critical electrical/software defect in the MBUX system which has completely blacked out. This VIN# has not been placed on recall but it is suffering the same failure as previous models (Including NHTSA campaign #21V354 and #26V281000 and I believe it warrants further investigation. The display failure creates significant safety hazards. Loff of Rear View Camera. Loss of Driver Instruments Warning. Essential driver information, including speed, safety warnings and system alerts while the vehicle is in motion, which creates a safety hazard. I have reached out to Mercedez corporate office, dealership, the issue remains unresolved. I request that NHTSA log this safety complaint and evaluate whether further enforcement or expended recall action is required to ensure Mercedes remedies this defect at no cost to vehicle owners.
I purchased my vehicle 2021 Mercedes-Benz GLE 350 from Mercedes Dealership in Ontario, and had it for only about 4 months before it catching on fire while parked at the doctors office. I purchased it [XXX], and it caught fire on [XXX] while at the doctors. I didn't drive much since I work from home. Primary reason for purchase was to have a working and safe vehicle to transport family to their doctor appointments. Mileage at purchase was 59982. Last mileage 60,292. Insurance currently has the vehicle at Copart in Colton while doing their investigation for the claim I filed. I have the police report and fire report as well. At the time of purchase, I asked if there was anything wrong or if any know issues with vehicle, I was reassured no issues. Reviewing the insurance CCC report, I come to find out the vehicle has 3 recalls with possibility of fire incidents. The carfax provided doesn't say that either recall issue was performed as another recall issue with the fuel pump was performed and disclosed. Beyond devastated that I have no vehicle now and that I expected this one to last much much longer. There was no indication of anything wrong with the vehicle, no warning lights nor check engine. Fire was indicated to start in engine compartment on the passengers side by the fire investigator. This incident affected 3 families. As a teacher, I find everyone's life precious and its sickening to know that my life and other lives were in danger. Had I waited 5 more minutes in the vehicle, I fear that this message may not have existed at all. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
