2026 Mercedes-Benz GLE 580 | ~2,800 miles | Mercedes-Benz of McKinney, McKinney, TX | No warning lamps preceded any failure.  ISSUE 1 â Instrument cluster blacks out while driving The speedometer and tachometer display goes completely black without warning at normal road speeds. The only remedy is stopping, shutting off the engine, waiting 10 minutes, and rebooting. Loss of speed and warning indicator visibility while driving creates immediate safety risk. Dealer is aware; no repair order on file.  ISSUE 2 â Auto stop/start shuts engine off while coasting The stop/start system incorrectly kills the engine at low speed without driver input. On restart, the engine hesitates and idles roughly. Unexpected engine shutdown reduces power steering and braking assist, creating a hazard in traffic. No warning precedes the event. Dealer is aware; no repair order on file.  ISSUE 3 â Transmission valve body failure; hard downshift persists after repair Abnormal transmission behavior required three dealer visits to diagnose. The valve body was replaced. The vehicle still exhibits a hard 5-to-4 downshift after repair. Abrupt downshifts during deceleration reduce predictable vehicle control. Repair orders are on file at Mercedes-Benz of McKinney. Issue remains unresolved.  Vehicle is available for inspection upon request and will be going back in to the dealer for repair services by 6/25/2026
