Low coolant warning light came on while driving. Parked car in garage and found engine coolant all over garage floor. Contacted dealer, topped off coolant per conversation with service advisor and drove car to dealership. Dealer found that a rock had entered through one of the grille openings and damaged the front radiator. Estimate of repairs was $2,037 which Mercedes offered to cover $1,000 of the repair. Concern is that this may very well happen again due to the design of the grille.

I received the attached Notice of Safety recall on 2/2/24 regarding an increase risk of crash due to a software error in the ESP unit. The letter also states that there is no remedy available yet. When I reached out to dealership who leased me the car they assured me that my car was safe to drive although no further explanation was given as to why they felt it was safe. And , I was further informed that they were prohibited from selling any vehicles in their inventory that were subject to the same recall as my vehicle.

2024 GLE450: This engine has twin turbos. On second day of ownership a "yellow turtle" warning light appeared on dash. This indicated loss of significant engine power (i.e. hence the "turtle mode"). This happened, without warning, multiple times on highway during first few days of ownership. I think this means the turbochargers were "deactivated" or taken "off line" by vehicle's management system. Result was suddenly compromised ability while passing and ability to maintain highway speed to safe exit. Checked vehicle in to MB Service Department (on day five of ownership) for analysis and repairs. Vehicle subsequently in shop for 29 days!; 8/3/23-8/31/23 Repair order is more than two pages, single spaced. Appears dealer Service Dept ultimately "Replaced crank case vapor oil separator on top of valve cover." I tried to upload Service Invoice but wouldn't let me do it.

The glass pane between my windshield and my dual-pane panoramic sunroof exploded while parked in my garage in the middle of the night. This car is not even 2 months old yet, has never been damaged and could have killed me had it randomly exploded while I was driving.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2024 Mercedes-benz GLE Phev verdict →
