Keyless entry problem. July 26, 2022 I placed my 2 small dogs and pursewith key in car. I was unable to enter car on drive's side because the key locked the car from inside. I have since learned from several people they experienced same problem (with infant in rearseat) and that if battery is low on key fob the car will lock with key inside. I attempted to reach MB roadside assistance but after 30 minute wait decision was made to break window to remove the dogs that were in distress. I did see message that same day on dashboard to replace the battery but had NO idea I should immediately do so or only use the "blade" key. I have been diligent about keeping car serviced but apparently battery wasn't replaced during routine service. I would have immediately replaced the battery if I knew key would malfunction thereby locking animals in car. Although I filed complaint with MB they denied my request to reimburse me the cost of replacing the window. I strongly encouraged them to advise service technicians to replace battery at scheduled service (my last service was 5 weeks earlier). I also recommended MB and local dealerships should have better response to calls when it's urgent. The possibility of locking pets or children in car is far more important than the $1900 cost to replace the window so I'm hoping you will take this seriously and advise all MB owners to frequently change batteries at certain intervals and advise service dept personnel to automatically do so. Again, I had no idea it was so important to immediitely do so.

The steering shifter would not change the car into park nor new Ram, from drive. Aff'L, the shifter instead began operating the navigation map cursor. The vehicle was stationary each of the 3 times it happened in one day.

From day one delivery, car technology didn't work. A couple of months, more problems began: Odd security warnings - car wouldn't let me put into park, nor neutral, nor reverse. This occurred 3 times, setting still, in 3 rural locations. Instead the shifter operated the central navigation map directions! two dealers couldn't fix. Investigation into history, the car had undisclosed damage to the steering column shifter. Parts were replaced before being titled to me. Mercedes refused to assist. At my expense I had car towed to the dealer who worked on the column shifter replacement. They determined the car was never set up properly by the dealer, and they also replaced relays for the steering column. Mercedes refused to acknowledge any of this even after the third dealer remedied. The fact they didn't set up security properly, causing potential safety problems unable to shift car transmission and there were no warnings of car not set up on dealer side, is extremely dangerous. They also never disclosed this car for adaquate operation needs to interact with other Mercedes cars. I can see additional features relying I this, but a car should never be inaccessible to the owner who had keys in hand, and owner did set up her profile in the car and with her phone. I was told the failures were faulty software, faulty relays, and the original dealer must set up car for proper security. This is not the first time I've experienced a dealer who didn't set up a car correctly. But the first time it never interfered with the car operation. Overall the car spent more time at the shop than in my possession the 7 months I leased it. Mercedes also wouldn't let me put of the lease and I had to pay substantial money to buy out the car. Mercedes I'm convinced thought I was scamming them to get out of the car. I've never been treated with such disrespect over a dangerous matter.
