2025 Mercedes-Benz GLE 450E 4MATIC Engine Problems

“This has happened twice. They “fixed” it and returned it to me and it did it again. I was about to pull out into traffic, once on the interstate and another time on a 2 lane highway… right as I hit the gas to pull out the car lurches forward and dies. Comes to a complete stop. It won’t crank back up, it won’t go into neutral or drive or reverse. The electoral system goes crazy and all lights start going off. One car had to go in the median to avoid colliding with me. I’m waiting on a police report but this was so scary I’m terrified to drive my car. …”

“Coolant hose was rubbing on the drive shaft and at 4,931 miles the coolant hose failed and the vehicle lost all coolant from the system. Fortunately the hose failed after the car was driven into our garage and not on the open highway. We had just returned from a 1,000 mile trip to Nashville, TN from Winston-Salem, NC. This is a PHEV and the coolant also effects the temperature of the EV batteries. This was a improper installation of the coolant hose. I have attached a picture that I took of the hose showing the rubbing on the drives shaft. …”

“GLE 450e Plug In-Hybrid. Car went into ‘Turtle Mode’ on Saturday March 8th for no known reason. Turtle Light and Check Engine warning lights came on and there was a warning message “Significant Reduction in Power”. My understanding this is a vehicle initiated precaution when something triggers the vehicle to go into reduced power mode. This all happened after the car had been driven on the highway for about 2.5 hours. It was running in gas engine mode since the battery power had been off for 1.5hrs. It was also about 30F in VT that day. The turtle mode came on as soon as we exited the highway. …”

“Vehicle goes into Turtle mode with the error that says Performance Extremely Limited. It happens without any warning and has already happened 3 times right now. Last night (December 8th, 2024) it happened as my wife was merging into the freeway. All of a sudden, the power got cut out almost completely. The Check engine light turned on, the Turtle symbol came ON and the message Performance Extremely Limited came on. She was lucky there was no traffic, but this could happen where there is traffic at speed coming and they can easily rear end our vehicle. This condition can't be safe. …”

“The vehicle loses power while driving and flashes Performance Extremely Limited. We have had this happen in intersections and while getting on the highway almost causing an accident on more than one occasion. When this occurs the vehicle decelerates quickly, will not use the batter and basic functions like the air conditioning stop working.”
