2022 Mercedes-benz SL-Class Complaints

  • Power Train, engine 05/17/2024

    When driven on the highway, speed drops abruptly down (65 mph to 40 mph) stuck on 4 or 3rd gear in this automatic 9 speed transmission and gear won't shift up causing engine rpm rise over 3000 & gas pedal won't have effect even it was pushed down to floor all the way. Almost rear ended in multiple occasion & it is extremely dangerous to change lane to get off to safety as car does not respond to throtle up or gas pedal to speed up. Dealer was not able to duplicate issue in two service visit & this already happened third time in a raw and car is back in dealership for diagnostic. No warning nor malfunction light at all when this happen
