Transmission Not Go Into Gear Problems of Mercedes Benz GL450

My car battery died, roadside assistance jumped my car, mechanic replaced my batteries. The car started without problems, but then a message came up in my dashboard in red saying to drive the car to the workshop without shifting gears; after the mechanic checked the car and did some research he found that the intelligent servo module was bad; the card would not shift into gear. The vehicle was stationary with the engine running in the shop.

(jb - was the dealer contacted or not?) tl the contact owns a 2007 mercedes-benz Gl450. While the vehicle was at a complete stop, it failed to shift gears without warning. The contact was able to pull the vehicle over, shut off and restart the vehicle, and then the gears operated correctly. The vehicle was taken to a local dealer where it was diagnosed that the vehicle went into limp mode and that the speed and pcu sensors failed and needed to be replaced. The vehicle was not repaired. The local dealer and manufacturer were not contacted. The failure mileage was approximately 130,000.

Transmission is getting stuck in a gear and not shifting up or down. The vehicle failed to shift and accelerate to maintain speed on an uphill incline on the highway. This was a scary and dangerous situation on the highway. I have had other failure to shift gear issues with this vehicle before and after this incident. The "fix" is to turn the car off and restart the vehicle. If this failure to shift gears occurs during a turn or other dangerous situation it can result in a fatality. I see numerous reports of this failure online from other '07 Gl450 owners. This has to be addressed.

I was driving at night on a local road when the transmission locked up and would not shift up a gear. I immediately got into the nearest plaza and put the car in park and turned off the engine. I then restarted the car and the transmission was shifting correctly and was not locking into a gear. This has happened to me twice already. It is a major safety concern as I could have been in an accident with the car behind me. I could have also damaged internal components in my SUV.
