2024 Mercedes-Benz GLE 400 E Other or unknown Problems

“While driving on the highway, my new Mercedes GLE450e, it suddenly stalled, and a 'turtle' symbol appeared on the dashboard. This indicated that the vehicle had entered 'limp mode.' At that point, I lost acceleration and had minimal power, making it difficult to maneuver safely.

During the third time in the shop, the dealer completely replaced the power electronics unit and cooler. …”

“On October 7, 2026, while driving my 2024 Mercedes-Benz GLC 450e plug-in hybrid on the freeway (I 280 south between Woodside and Sand Hill Road) the panoramic sunroof suddenly shattered with an extremely loud, explosive sound. We did not see anything strike the vehicle, and there was no car immediately in front of us, so nothing was kicked up from another car. The glass shattered extensively, with much of it breaking away while we continued driving. Fortunately, the interior sunshade was closed and remained intact, preventing shattered glass from entering the passenger compartment. …”
