Powertrain (other)
Filed Nov 21, 2025

The vehicle has an ongoing transmission downshifting malfunction. The powertrain unexpectedly downshifts while driving, causing sudden changes in speed and unstable vehicle behavior. The issue can be inspected at any time, as the defect occurs intermittently and has not been repaired. This malfunction puts my safety and the safety of others at risk because the vehicle can slow down abruptly or shift aggressively without any input from the driver. This can create dangerous situations in traffic, especially at highway speeds or during acceleration. The problem has been reproduced and observed multiple times by the Mercedes-Benz dealership. I have taken the vehicle to the service center repeatedly for this same issue. Most recently, the vehicle remained at the service center for 10 consecutive days, but the defect was not resolved. The vehicle has been inspected by Mercedes-Benz technicians on several occasions. Despite multiple repair attempts, the issue continues to occur. There were no warning lamps or dashboard messages prior to the malfunction. The issue first appeared months ago and has persisted despite repeated service visits and repair attempts.

There wasn't a field for my exact issue but my exact issue along with many others is the lack of power when accelerating in first gear. The car has an extremely numb feeling when starting out in first gear and does not takeoff like it should. There have been many Times where I accelerate and the car hesitates then I get a transmission jolt Or the car just does not accelerate immediately when I push on the gas from a stop. This is causing me to not pull out in front of cars in fear the car will hesitate which is a safety issue. this has been going on ever since we got the car a few months ago. The dealership says the vehicle is "operating as designed however this is a poor excuse" i've had owned dozens of vehicles in the past 28 years and not one of them has had poor acceleration like this. I've owned cars with a quarter of the horsepower of this vehicle that accelerate better from first gear.
